<p>I need to search a string and replace all occurrences of <code>%FirstName%</code> and <code>%PolicyAmount%</code> with a value pulled from a database. The problem is the capitalization of FirstName varies. That prevents me from using the <code>String.Replace()</code> method. I've seen web pages on the subject that suggest</p>
<pre><code>Regex.Replace(strInput, strToken, strReplaceWith, RegexOptions.IgnoreCase);
</code></pre>
<p>However for some reason when I try and replace <code>%PolicyAmount%</code> with <code>$0</code>, the replacement never takes place. I assume that it has something to do with the dollar sign being a reserved character in regex. </p>
<p>Is there another method I can use that doesn't involve sanitizing the input to deal with regex special characters?</p>

<p>I'm sure this is a relatively simple question, and there must be a good sensible rails way of doing it, but I'm not sure what it is.</p>
<p>Basically I'm adding books to a database, and I want to store the Author in a separate table. So I have a table called authors which is referenced by the table books.</p>
<p>I want to create a rails form for adding a book, and I'd like it to be just a simple form for Author, Title, Publisher etc, and if it finds the author already in the authors table then it should just reference that record, and if it isn't in the authors table then it should add a new record and reference it.</p>
<p>I'm sure there's an easy way of doing this in rails - but I can't seem to find it.</p>
<p>Cheers,</p>
<p>Robin</p>

<p>I was kind of scratching my head at this a week ago, and now with a little bit more Cocoa experience under my belt I feel like I have an inkling as to what might be going on. </p>
<p>I'm making an application that is driven by a UINavigationController. In the AppDelegate, I create an instance of this class, using "page 1" as the Root View Controller.</p>
<pre><code>UINavigationController *aNavigationController = [[UINavigationController alloc]
initWithRootViewController:page1ViewController];
</code></pre>
<p>Now here's where I'm having the problem. From "page 1" I'd like to use a modal view controller that slides over the interface and then disappears once the user has made an edit. I do that using code like this, inside of Page1ViewController:</p>
<pre><code>[self presentModalViewController:myModalViewController animated:YES];
</code></pre>
<p>When the Modal View Controller is gone, I want a value on "Page 1" to change based on what the user entered in the Modal View Controller. So, I wrote some code like this, which resides in the Modal View Controller: </p>
<pre><code>[self.parentViewController dismissModalViewControllerAnimated:YES];
[self.parentViewController doSomethingPleaseWithSomeData:someData];
</code></pre>
<p>The update to page 1 wasn't happening, and it took me a long time to realize that the "doSomethingPleaseWithSomeData" message was not being sent to Page1ViewController, but the Navigation Controller. </p>
<p>Is this always to be expected when using Navigation Controllers? Did I perhaps configure something improperly? Is there an easy way to get at the View Controller that I want (in this case, Page1ViewController).</p>

<p>This is baffling me, maybe somebody can shine the light of education on my ignorance. This is in a C# windows app. I am accessing the contents of a listbox from a thread. When I try to access it like this<pre><code>prgAll.Maximum = lbFolders.SelectedItems.Count;</code></pre>
I get the error. However, here is the part I don't get. If I comment out that line, the very next line<pre><code>foreach (string dir in lbFolders.SelectedItems)</code></pre>
executes just fine.</p>
<p>Edit:
As usual, my communication skills are lacking. Let me clarify.</p>
<p>I know that accessing GUI items from threads other than the ones they were created on causes problems. I know the right way to access them is via delegate.</p>
<p>My question was mainly this:
Why can I access and iterate through the SelectedItems object just fine, but when I try to get (not set) the Count property of it, it blows up.</p>

<p>I have YAML data that looks sort of like this, but ~150k of it:</p>
<pre><code>---
all:
foo: 1025
bar:
baz: 37628
quux:
a: 179
b: 7
</code></pre>
<p>...or the same thing in JSON:</p>
<pre><code>{"all":{"bar":{"baz":"37628","quux":{"a":"179","b":"7"}},"foo":"1025"}}
</code></pre>
<p>I want to present this content in an expandable JavaScripty HTML tree view (examples: <a href="http://developer.yahoo.com/yui/examples/treeview/default_tree.html" rel="noreferrer">1</a>, <a href="http://www.mattkruse.com/javascript/mktree/" rel="noreferrer">2</a>) to make it easier to explore. How do I do this?</p>
<p>I guess what I really want to figure out is how to take this YAML/JSON data, and automatically display it as a tree (with hash keys sorted alphabetically). So far, I've been tussling with <a href="http://developer.yahoo.com/yui/treeview/" rel="noreferrer">YUI's tree view</a>, but it doesn't accept straight JSON, and my feeble attempts to massage the data into something useful don't seem to be working.</p>
<p>Thanks for any help.</p>

<p>I'm looking at the output from spring being loaded up by tomcat and there's something very strange...Everything is duplicated. What would cause this? Whatever it is, it's causing my application to run in odd ways.</p>
<p><strong>Additional Info:</strong></p>
<p>The application is a web app. All the spring information is loaded using the context loader(?) defined in the web.xml file. My configuration files are split amoung 6 (or so) files.</p>
<p>Example debug output:</p>
<blockquote>
<p>[DEBUG,DefaultFilterInvocationDefinitionSource,main] Added URL pattern: /<code>**</code>; attributes: [REQUIRES_SECURE_CHANNEL]</p>

<p>I've got several developers about to start working on the front end of a jquery-based web application. How can we structure the application so that multiple developers can work on the ui at the same time. The end result for the user will just be one web "page", but I don't all of the client development to occur in one file. There is already another team working on the back end.</p>

<p>I have a medium size Java file. Everytime I make a change to one of my files, BuildTable.java, Git reports it as a massive change, even if is only a line or two. BuildTable.java is about 200 lines and the change in this commit only changed a single line.</p>
<p>git-diff ouputs this:</p>

<p>I am having difficulty refreshing windows forms controls that are using a BindingSource object. We have a CAB/MVP/SCSF client that I (actually “we” since it is a team effort) are developing that will interact with WCF services running on a remote server. (This is our first attempt at this, so we are in a learning mode). One of the calls (from the Presenter) to the service returns a DataSet that contains 3 DataTables, named “Contract”, “Loan” and “Terms”. Each table contains just one row. When the service returns the dataset, we store it in the SmartPart/View in a class member variable, by calling a function in the view called BindData() and passing the dataset in to the view from the presenter class;</p>
<pre><code>private System.Data.DataSet _ds = null;
public void BindData(System.Data.DataSet ds)
{
string sErr = "";
try
{
_ds = ds; // save to private member variable
// more code goes down here
}
}
</code></pre>
<p>We are trying to bind each of the three DataTables to an assortment of Windows Forms TextBoxes, MaskedEditBoxes, and Infragistics UltraComboEditor Dropdown comboboxes We created three BindingSource objects, one for each DataTable using the VS2008 IDE.</p>
<pre><code>private System.Windows.Forms.BindingSource bindsrcContract;
private System.Windows.Forms.BindingSource bindsrcLoan;
private System.Windows.Forms.BindingSource bindsrcTerms;
</code></pre>
<p>We are binding the values like this</p>
<pre><code>if (bindsrcContract.DataSource == null)
{
bindsrcContract.DataSource = _ds;
bindsrcContract.DataMember = “contract”;
txtContract.DataBindings.Add(new Binding("Text", bindsrcContract, "contract_id", true));
txtLateFeeAmt.DataBindings.Add(new Binding("Text", bindsrcContract, "fee_code", true));
txtPrePayPenalty.DataBindings.Add(new Binding("Text", bindsrcContract, "prepay_penalty", true));
txtLateFeeDays.DataBindings.Add(new Binding("Text", bindsrcContract, "late_days", true));
}
if (bindsrcLoan.DataSource == null)
{
bindsrcLoan.DataSource = _ds;
bindsrcLoan.DataMember = “loan”;
mskRecvDate.DataBindings.Add(new Binding("Text", bindsrcLoan, "receive_date", true));
cmboDocsRcvd.DataBindings.Add(new Binding("Value", bindsrcLoan, "docs", true));
}
</code></pre>
<p>This works when we do the first read from the service and get a dataset back. The information is displayed on the form's controls, we can update it using the form, and then “save” it by passing the changed values back to the WCF service.</p>
<p>Here is our problem. If we select a different loan key and make the same call to the service and get a new DataSet, again with 3 tables with one row each, the controls (textboxes, masked edit boxes, etc.) are not being updated with the new information. Note that the smartPart/View is not closed or anything, but remains loaded in between calls to the service. On the second call we are not rebinding the calls, but simply trying to get the data to refresh from the updated DataSet.</p>
<p>We have tried everything we can think of, but clearly we are missing something. This is our first attempt at using the BindingSource control. We have tried</p>
<pre><code>bindsrcContract.ResetBindings(false);
</code></pre>
<p>and </p>
<pre><code>bindsrcContract.ResetBindings(true);
</code></pre>
<p>and </p>
<pre><code>bindsrcContract.RaiseListChangedEvents = true;
</code></pre>
<p>and </p>
<pre><code>for (int i = 0; i < bindsrcContract.Count; i++)
{
bindsrcContract.ResetItem(i);
}
</code></pre>
<p>As well as resetting the DataMember property again.</p>
<pre><code>bindsrcContract.DataMember = ”Contract”;
</code></pre>
<p>We’ve looked at a lot of examples. Many examples make reference to the BindingNavigator but since the DataTables only have one row, we did not think we needed that. There are a lot of examples for grids, but we’re not using one here. Can anyone please point out where we are going wrong, or point us to resources that will provide some more information?</p>
<p>We’re using VisualStudio 2008, C# and .Net 2.0, XP client, W2K3 server.</p>
<p>Thanks in advance</p>
<p>wes</p>

<p>I'm looking for the equivalent in Qt to <code>GetTickCount()</code></p>
<p>Something that will allow me to measure the time it takes for a segment of code to run as in:</p>
<pre><code>uint start = GetTickCount();
// do something..
uint timeItTook = GetTickCount() - start;
</code></pre>
<p>any suggestions?</p>

<p>Sign. My tsql kungfu sucks. I have a fee that is of type small money. When I exported as SQL from MS Access the column that represents the fee was stored as text, for example $3.28 was stored as "00000328". When I imported this into MS SQLServer I changed the data type to smallmoney, but it was stored as 328. How do I make all the values on that column to move the "." two digits over to the left. </p>

<p>I'm looking for an UPDATE statement where it will update a single duplicate row only and remain the rest (duplicate rows) intact
as is, using ROWID or something else or other elements to utilize in Oracle SQL or PL/SQL?</p>
<p>Here is an example duptest table to work with:</p>
<pre><code>CREATE TABLE duptest (ID VARCHAR2(5), NONID VARCHAR2(5));
</code></pre>
<ul>
<li><p>run one <code>INSERT INTO duptest VALUES('1','a');</code> </p></li>
<li><p>run four (4) times <code>INSERT INTO duptest VALUES('2','b');</code> </p></li>
</ul>
<p>Also, the first duplicate row has to be updated (not deleted), always, whereas the other three (3) have to be remained as is!</p>
<p>Thanks a lot,
Val.</p>

<p>Can it be known in general whether or not placing a case within a for loop will result in bad assembly. I'm interested mainly in Delphi, but this is an interesting programming question, both in terms of style and performance. </p>
<p>Here are my codez!</p>
<pre>
case ResultList.CompareType of
TextCompareType:
begin
LastGoodIndex := -1;
for I := 1 to ResultList.Count -1 do
if (LastGoodIndex = -1) and (not ResultList[I].Indeterminate) then
LastGoodIndex := I
else if not ResultList[I].Indeterminate then
begin
if (StrComp(ResultList[LastGoodIndex].ResultAsText,
ResultList[I].ResultAsText) > 0)
and (Result FalseEval) then
Result := TrueEval
else
Result := FalseEval;
LastGoodIndex := I;
end;
end;
end;
NumericCompareType:
begin
//Same as above with a numeric comparison
end;
DateCompareType:
begin
//Same as above with a date comparison
end;
BooleanCompareType:
begin
//Same as above with a boolean comparison
end;
</pre>
<p>alternatively I could write </p>
<pre>
begin
LastGoodIndex := -1;
for I := 1 to ResultList.Count -1 do
if (LastGoodIndex = -1) and (not ResultList[I].Indeterminate) then
LastGoodIndex := I
else if not ResultList[I].Indeterminate then
begin
case ResultList.CompareType of
TextCompareType:
begin
if (StrComp(ResultList[LastGoodIndex].ResultAsText,
ResultList[I].ResultAsText) > 0)
and (Result FalseEval) then
Result := TrueEval
else
Result := FalseEval;
LastGoodIndex := I;
end;
NumericCompareType:
begin
//Same as above with a numeric comparison
end;
DateCompareType:
begin
//Same as above with a date comparison
end;
BooleanCompareType:
begin
//Same as above with a boolean comparison
end;
end;
end;
end;
</pre>
<p>I don't like the second way because I'm asking a question I know the answer to in a for loop and I don't like the first way because I'm repeating the code I use to figure out which of my objects contain valid information. </p>
<p>Perhaps there is a design pattern someone could suggest that would circumvent this all together.</p>

<p>The structures of my Git repositories look like this:</p>
<pre><code>A-B-C-D-E-F # master branch in separate repo1
A-B-C-D-E-G-H # master branch in separate repo2
</code></pre>
<p>A-H are simple commits. As you can see the repositories are related (repo2 is a fork of repo1). I'm trying to combine these two repositories in one.</p>
<p>Afterwards the single repository should have the following structure:</p>
<pre><code>A-B-C-D-E-F # master branch of previous repo1
\
\
G-H # master branch of previous repo2
</code></pre>
<p>I've already spent a lot of time reading the Git User's Guide and so on. However, this (special) case of use doesn't seem to be documented anywhere.</p>

<p>I'm debating the best way to propagate fairly complex permissions from the server to an AJAX application, and I'm not sure the best approach to take.</p>
<p>Essentially, I want my permissions to be defined so I can request a whole set of permissions in one shot, and adjust the UI as appropriate (the UI changes can be as low level as disabling certain context menu items). Of course, I still need to enforce the permissions server side. </p>
<p>So, I was wondering if anyone has any suggestions for the best way to</p>
<ol>
<li>maintain the permissions and use them in server code</li>
<li>have easy access to the permissions in javascript</li>
<li>not have to make a round-trip request to the server for each individual permission</li>
</ol>
<p>Thoughts?</p>

<p>Because I need to display a <a href="http://codeflow.org/ubuntu.png" rel="nofollow noreferrer">huge number of labels</a> that <a href="http://www.youtube.com/watch?v=A_ah-SE-cNY" rel="nofollow noreferrer">move independently</a>, I need to render a label in <a href="http://pyglet.org" rel="nofollow noreferrer">pyglet</a> to a texture (otherwise updating the vertex list for each glyph is too slow).</p>
<p>I have a solution to do this, but my problem is that the texture that contains the glyphs is black, but I'd like it to be red. See the example below:</p>
<pre><code>from pyglet.gl import *
def label2texture(label):
vertex_list = label._vertex_lists[0].vertices[:]
xpos = map(int, vertex_list[::8])
ypos = map(int, vertex_list[1::8])
glyphs = label._get_glyphs()
xstart = xpos[0]
xend = xpos[-1] + glyphs[-1].width
width = xend - xstart
ystart = min(ypos)
yend = max(ystart+glyph.height for glyph in glyphs)
height = yend - ystart
texture = pyglet.image.Texture.create(width, height, pyglet.gl.GL_RGBA)
for glyph, x, y in zip(glyphs, xpos, ypos):
data = glyph.get_image_data()
x = x - xstart
y = height - glyph.height - y + ystart
texture.blit_into(data, x, y, 0)
return texture.get_transform(flip_y=True)
window = pyglet.window.Window()
label = pyglet.text.Label('Hello World!', font_size = 36)
texture = label2texture(label)
@window.event
def on_draw():
hoff = (window.width / 2) - (texture.width / 2)
voff = (window.height / 2) - (texture.height / 2)
glClear(GL_COLOR_BUFFER_BIT)
glEnable(GL_BLEND)
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
glClearColor(0.0, 1.0, 0.0, 1.0)
window.clear()
glEnable(GL_TEXTURE_2D);
glBindTexture(GL_TEXTURE_2D, texture.id)
glColor4f(1.0, 0.0, 0.0, 1.0) #I'd like the font to be red
glBegin(GL_QUADS);
glTexCoord2d(0.0,1.0); glVertex2d(hoff,voff);
glTexCoord2d(1.0,1.0); glVertex2d(hoff+texture.width,voff);
glTexCoord2d(1.0,0.0); glVertex2d(hoff+texture.width,voff+texture.height);
glTexCoord2d(0.0,0.0); glVertex2d(hoff, voff+texture.height);
glEnd();
pyglet.app.run()
</code></pre>
<p>Any idea how I could color this?</p>

<p>I want to setup a CRON that runs a PHP script that in turn moves XML file (holding non-sensitive information) from one server to another. </p>
<p>I have been given the proper username/password, and want to use SFTP protocol. The jobs will run daily. There is the potential that one server is Linux and the other is Windows. Both are on different networks. </p>
<p>What is the best way to move that file?</p>

<p>So this might be really simple, but I haven't been able to find any examples to learn off of yet, so please bear with me. ;) </p>
<p>Here's basically what I want to do:</p>
<pre><code><div>Lots of content! Lots of content! Lots of content! ...</div>
....
$("div").html("Itsy-bitsy bit of content!");
</code></pre>
<p>I want to smoothly animate between the dimensions of the div with lots of content to the dimensions of the div with very little when the new content is injected.</p>
<p>Thoughts?</p>

<p>I'm creating a series of builders to clean up the syntax which creates domain classes for my mocks as part of improving our overall unit tests. My builders essentially populate a domain class (such as a <code>Schedule</code>) with some values determined by invoking the appropriate <code>WithXXX</code> and chaining them together.</p>
<p>I've encountered some commonality amongst my builders and I want to abstract that away into a base class to increase code reuse. Unfortunately what I end up with looks like:</p>
<pre><code>public abstract class BaseBuilder<T,BLDR> where BLDR : BaseBuilder<T,BLDR>
where T : new()
{
public abstract T Build();
protected int Id { get; private set; }
protected abstract BLDR This { get; }
public BLDR WithId(int id)
{
Id = id;
return This;
}
}
</code></pre>
<p>Take special note of the <code>protected abstract BLDR This { get; }</code>.</p>
<p>A sample implementation of a domain class builder is:</p>
<pre><code>public class ScheduleIntervalBuilder :
BaseBuilder<ScheduleInterval,ScheduleIntervalBuilder>
{
private int _scheduleId;
// ...
// UG! here's the problem:
protected override ScheduleIntervalBuilder This
{
get { return this; }
}
public override ScheduleInterval Build()
{
return new ScheduleInterval
{
Id = base.Id,
ScheduleId = _scheduleId
// ...
};
}
public ScheduleIntervalBuilder WithScheduleId(int scheduleId)
{
_scheduleId = scheduleId;
return this;
}
// ...
}
</code></pre>
<p>Because BLDR is not of type BaseBuilder I cannot use <code>return this</code> in the <code>WithId(int)</code> method of <code>BaseBuilder</code>.</p>
<p>Is exposing the child type with the property <code>abstract BLDR This { get; }</code> my only option here, or am I missing some syntax trick?</p>
<p>Update (since I can show why I'm doing this a bit more clearly):</p>
<p>The end result is to have builders that build profiled domain classes that one would expect to retrieve from the database in a [programmer] readable format. There's nothing wrong with...</p>
<pre><code>mock.Expect(m => m.Select(It.IsAny<int>())).Returns(
new Schedule
{
ScheduleId = 1
// ...
}
);
</code></pre>
<p>as that's pretty readable already. The alternative builder syntax is:</p>
<pre><code>mock.Expect(m => m.Select(It.IsAny<int>())).Returns(
new ScheduleBuilder()
.WithId(1)
// ...
.Build()
);
</code></pre>
<p>the advantage I'm looking for out of using builders (and implementing all these <code>WithXXX</code> methods) is to abstract away complex property creation (automatically expand our database lookup values with the correct <code>Lookup.KnownValues</code> without hitting the database obviously) and having the builder provide commonly reusable test profiles for domain classes...</p>
<pre><code>mock.Expect(m => m.Select(It.IsAny<int>())).Returns(
new ScheduleBuilder()
.AsOneDay()
.Build()
);
</code></pre>

<p>I have the following <code>before_filter</code>:</p>
<pre><code> def find_current_membership
respond_to do |wants|
wants.html { @current_membership = @group.memberships.for(@current_user) }
wants.rss {}
wants.js { @current_membership = @group.memberships.for(@current_user) }
end
end
</code></pre>
<p>I would like to share the code for the HTML and JS blocks. Is there a better way than just throwing the code into a method? I was hoping this would work:</p>
<pre><code> def find_current_membership
respond_to do |wants|
wants.rss {}
wants.all { @current_membership = @group.memberships.for(@current_user) }
end
end
</code></pre>
<p>But alas, it did not.</p>

<p>I have a c# site which makes use of a lot of images with embedded english text. </p>
<p>How can I use a standard resource file to swap out images depending on the language?</p>
<p>I have a resx file in my App_GlobalResources directory, but I can't seem to get it plugged into an asp:image control for the imageurl correctly.</p>
<p>Ideas?</p>
<p><strong>UPDATE:</strong> </p>
<p>For some further information, here is the image tag code:</p>
<pre><code><asp:image runat="server" ID="img2" ImageUrl="<%$Resources: Resource, cs_logo %>" />
</code></pre>
<p>The result on the client side is:</p>
<pre><code><img id="img2" src="System.Drawing.Bitmap" style="border-width:0px;" />
</code></pre>
<p>Note that the source is obviously not what I expected...</p>

<p>Simple question really - how do I use <code>text_field_with_auto_complete</code> inside a <code>form_for</code> block?</p>
<p>I've tried doing <code>f.text_field_with_auto_complete</code> but that gives an error, and just using <code>text_field_with_auto_complete</code> by itself doesn't seem to do anything.</p>
<p>Am I missing something here?</p>

<p>For my web service component, I need to generate a relatively large XML (~500 lines) according to many factors. I am facing a few different choices here:
1. StringBuilder
2. XmlWriter class
3. C# object with serialization???</p>
<p>Which one should I use. Is there any other ways that I am not aware of?</p>

<p>I have an existing database with the table Transactions in it. I have added a new table called TransactionSequence where each transaction will ultimately have only one record. We are using the sequence table to count transactions for a given account. I have mapped this as a one-to-one mapping where TransactionSequence has a primary key of TransactionId. </p>
<p>The constraint is that there is an instead of trigger on the transaction table does not allow updates of cancelled or posted transactions. </p>
<p>So, when the sequence is calculated and the transaction is saved, NHibernate tries to send an update on the transaction like 'UPDATE Transaction SET TransactionId = ? WHERE TransactionId = ?'. But this fails because of the trigger. How can I configure my mapping so that NHibernate will not try to update the Transaction table when a new TransactionSequence table is inserted?</p>
<p>Transaction mapping:</p>
<pre><code><class name="Transaction" table="Transaction" dynamic-update="true" select-before-update="true">
<id name="Id" column="ID">
<generator class="native" />
</id>
<property name="TransactionTypeId" access="field.camelcase-underscore" />
<property name="TransactionStatusId" column="DebitDebitStatus" access="field.camelcase-underscore" />
<one-to-one name="Sequence" class="TransactionSequence" fetch="join"
lazy="false" constrained="false">
</one-to-one>
</class>
</code></pre>
<p>And the sequence mapping:</p>
<pre><code><class name="TransactionSequence" table="TransactionSequence" dynamic-update="true">
<id name="TransactionId" column="TransactionID" type="Int32">
<generator class="foreign">
<param name="property">Transaction</param>
</generator>
</id>
<version name="Version" column="Version" unsaved-value="-1" access="field.camelcase-underscore" />
<property name="SequenceNumber" not-null="true" />
<one-to-one name="Transaction"
class="Transaction"
constrained="true"
foreign-key="fk_Transaction_Sequence" />
</class>
</code></pre>
<p>Any help would be greatly appreciated...</p>

<p>I'm stuck with .Net 1.1 application (i.e. I can not use the generics goodies from 2.0 for now), and I was trying to optimize some parts of the code. As it deals a lot with runtime callable wrappers, which need to be released, I ended up to create a utility method which loops until all references are released. The signature of the method is:</p>
<pre><code>void ReleaseObject(object comObject)
</code></pre>
<p>After releasing all comObjects, I call GC.Collect and GC.WaitForPendingFinalizers (don't ask - anybody dealing with Office interop knows).</p>
<p>And ... as usual, I hit a corner case - if I do not assign the corresponding managed reference to null before the GC.Collect call, it does not cleanup properly.</p>
<p>So, my code looks like:</p>
<pre><code>ReleaseObject(myComObject);
myComObject = null;
GC.Collect()
...
</code></pre>
<p>As, there are a bunch of xxx=null, I decided to put this in the util method, but as there is a difference between passing by reference, and passing a reference parameter, obviously I had to change the method to:</p>
<pre><code>void ReleaseObject(out object comObject)
{
//do release
comObject = null;
}
</code></pre>
<p>and edit the caller to:</p>
<pre><code>MyComClass myComObject = xxxx;
ReleaseObject(out myComObject);
</code></pre>
<p>This fails with a message: "Cannot convert from 'out MyComClass' to 'out object'"</p>
<p>While I can think of why it can be a problem (i.e. the reverse cast from object to MyComClass is not implicit, and there is no guarantee what the method will do), I was wondering if there is a workaround, or I need to stay with my hundreds assignments of nulls.</p>
<p>Note: I have a bunch of different COM objects types, thats why I need a "object" parameter, and not a type safe one.</p>

<p>I have a custom webpart that is displaying dynamic list data, it needs to render an image from a Picture Library (or at least provide me the URL so I can encapsulate it with an tag), however, none of the fields in the Picture Library seem to contain the image URL? Is there a 'image utility' (SPImageUtility) or something I can use to pull this out? Or am I simply missing something?</p>

<p>We are re-platforming for a client, and they are concerned about SEO. Their current site supports SEO friendly URLs, and so does the new platform. So for those, we are just going to create the same URL mapping. However, they have a large number of other URLs that are not SEO friendly that they want to permanently redirect. These do not follow a similar pattern, so one regex in an .htaccess won't cut it. What is the best way to handle this on a LAMP stack? The application has a front controller too, so I need to make sure that works along with the hard redirects.</p>

<p>I'm really stumped on this one. I want to output a list and have the tag file take care of commas, singular versus plural, etc. but when I display the list it completely ignores whitespace so everythingrunstogetherlikethis. I tried using the HTML entities "thinsp", "ensp" and "emsp" (I can't use "nbsp", these have to be breaking), but they're all hideously wide on IE except thinsp which is way too skinny on everything else.</p>
<p>Edit:
won't work. The output from the tag has no spaces at all. Although any content in the JSP has normal spacing. Obviously I could just put everything in the JSP but this is code that goes on multiple JSPs, so tag files would make a lot of sense.</p>

<p>I have a protected Excel worksheet, without a password.
What I'd like to do is trap the event that a user unprotects the worksheet, so that I can generate a message (and nag 'em!). I can setup event checking for the application, for when new workbooks are opened, etc., but not for Unprotect.<br>
Does anyone have an idea?</p>

<p>I need to match a string like "one. two. three. four. five. six. seven. eight. nine. ten. eleven" into groups of four sentences. I need a regular expression to break the string into a group after every fourth period. Something like: </p>
<pre><code> string regex = @"(.*.\s){4}";
System.Text.RegularExpressions.Regex exp = new System.Text.RegularExpressions.Regex(regex);
string result = exp.Replace(toTest, ".\n");
</code></pre>
<p>doesn't work because it will replace the text before the periods, not just the periods themselves. How can I count just the periods and replace them with a period and new line character?</p>

<p>I'm writing an application and I'm trying to tie simple AJAX functionality in. It works well in Mozilla Firefox, but there's an interesting bug in Internet Explorer: Each of the links can only be clicked once. The browser must be completely restarted, simply reloading the page won't work. I've written a <a href="http://static.stillinbeta.com/page/" rel="noreferrer">very simple example application</a> that demonstrates this.</p>
<p>Javascript reproduced below:</p>
<pre><code>var xmlHttp = new XMLHttpRequest();
/*
item: the object clicked on
type: the type of action to perform (one of 'image','text' or 'blurb'
*/
function select(item,type)
{
//Deselect the previously selected 'selected' object
if(document.getElementById('selected')!=null)
{
document.getElementById('selected').id = '';
}
//reselect the new selcted object
item.id = 'selected';
//get the appropriate page
if(type=='image')
xmlHttp.open("GET","image.php");
else if (type=='text')
xmlHttp.open("GET","textbox.php");
else if(type=='blurb')
xmlHttp.open("GET","blurb.php");
xmlHttp.send(null);
xmlHttp.onreadystatechange = catchResponse;
return false;
}
function catchResponse()
{
if(xmlHttp.readyState == 4)
{
document.getElementById("page").innerHTML=xmlHttp.responseText;
}
return false;
}
</code></pre>
<p>Any help would be appreciated.</p>

<p>How can I inject the value of an appSettings entry (from app.config or web.config) into a service using the Windsor container? If I wanted to inject the value of a Windsor property into a service, I would do something like this:</p>
<pre><code><properties>
<importantIntegerProperty>666</importantIntegerProperty>
</properties>
<component
id="myComponent"
service="MyApp.IService, MyApp"
type="MyApp.Service, MyApp"
>
<parameters>
<importantInteger>#{importantIntegerProperty}</importantInteger>
</parameters>
</component>
</code></pre>
<p>However, what I'd really like to do is take the value represented by <code>#{importantIntegerProperty}</code> from an app settings variable which might be defined like this:</p>
<pre><code><appSettings>
<add key="importantInteger" value="666"/>
</appSettings>
</code></pre>
<p><strong>EDIT:</strong> To clarify; I realise that this is not natively possible with Windsor and the <a href="http://davidhayden.com/blog/dave/archive/2007/10/04/DependencyInjectionParametersPropertiesCastleWindsor.aspx" rel="nofollow noreferrer">David Hayden article</a> that <a href="https://stackoverflow.com/users/31385/sliderhouserules">sliderhouserules</a> refers to is actually about his own (David Hayden's) IoC container, not Windsor.</p>
<p>I'm surely not the first person to have this problem so what I'd like to know is how have other people solved this issue?</p>

Files are added approximately once a minute and the naming goes like this... image0001.jpg, image0002.jpg, image0003.jpg etc. I need to know when a file has been written to the folder so that my app can access and use it.</p>

<p>I am creating a small web page using PHP that will be accessed as an IFRAME from a couple of sites. I'm wanting to restrict access to this site to work ONLY within the "approved" sites, and not other sites or accessed directly. Does anyone have any suggestions? Is this even possible? The PHP site will be Apache, and the sites iframing the content will probably be .NET.</p>
<p>Just to clarify, any site can view the page, as long as it's iframe'd within an approved site. I want to block people from accessing it directly. I'm thinking cookies might be a solution, but I'm not sure.</p>

<p>I've tried to add the [System.Xml.Serialization.XmlElement(IsNullable=false)] attribute, but I get a runtime serialization exception saying there was a an error reflecting the type, because "IsNullable may not be set to 'false' for a Nullable type. Consider using 'System.Int32' type or removing the IsNullable property from the XmlElement attribute."</p>
<pre><code>[Serializable]
[System.Xml.Serialization.XmlRoot("Score", Namespace = "http://mycomp.com/test/score/v1")]
public class Score
{
private int? iID_m;
...
/// <summary>
///
/// </summary>
public int? ID
{
get
{
return iID_m;
}
set
{
iID_m = value;
}
}
...
}
</code></pre>
<p>The above class will serialize to:</p>
<pre><code><Score xmlns="http://mycomp.com/test/score/v1">
<ID xsi:nil="true" />
</Score>
</code></pre>
<p>But for IDs that are null I don't want the ID element at all, primarily because when I use OPENXML in MSSQL, it returns a 0 instead of null for an element that looks like </p>

<p>Suppose I have the following two strings containing regular expressions. How do I coalesce them? More specifically, I want to have the two expressions as alternatives.</p>
<pre><code>$a = '# /[a-z] #i';
$b = '/ Moo /x';
$c = preg_magic_coalesce('|', $a, $b);
// Desired result should be equivalent to:
// '/ \/[a-zA-Z] |Moo/'
</code></pre>
<p>Of course, doing this as string operations isn't practical because it would involve parsing the expressions, constructing syntax trees, coalescing the trees and then outputting another regular expression equivalent to the tree. I'm completely happy without this last step. Unfortunately, PHP doesn't have a RegExp class (or does it?).</p>
<p>Is there <em>any</em> way to achieve this? Incidentally, does any other language offer a way? Isn't this a pretty normal scenario? Guess not. :-(</p>
<p><strong>Alternatively</strong>, is there a way to check <strong>efficiently</strong> if either of the two expressions matches, and which one matches earlier (and if they match at the same position, which match is longer)? This is what I'm doing at the moment. Unfortunately, I do this on long strings, very often, for more than two patterns. The result is <em>slow</em> (and yes, this is definitely the bottleneck).</p>
<h2>EDIT:</h2>
<p>I should have been more specific – sorry. <code>$a</code> and <code>$b</code> are <em>variables</em>, their content is outside of my control! Otherwise, I would just coalesce them manually. Therefore, I can't make any assumptions about the delimiters or regex modifiers used. Notice, for example, that my first expression uses the <code>i</code> modifier (ignore casing) while the second uses <code>x</code> (extended syntax). Therefore, I can't just concatenate the two because the second expression does <em>not</em> ignore casing and the first doesn't use the extended syntax (and any whitespace therein is significant!</p>

<p>How can it be changed programmatically? Which API-call or registry-setting can be used to change this setting?</p>

<p>...I want to Show the 'delete' button when user is an admin, and show the 'add item' button when user is a contributor:</p>

</asp:TemplateField>
</Columns>
<SelectedRowStyle VerticalAlign="Top" />
<HeaderStyle ForeColor="White" CssClass="TableHeader" BackColor="SteelBlue" />

</code></pre>
<p>The Delete button 'visible' attribute works fine. But, the "add item' hyperlink doesn't. It always shows.
View-source tells me that %# User.IsInRole(@"DOMAIN\CMDB_CONTRIBUTE") %> isn't evaluating to anything. Any idea why this is?</p>

<p>I'm looking for a way to add a close button to a .NET ToolTip object similar to the one the NotifyIcon has. I'm using the tooltip as a message balloon called programatically with the Show() method. That works fine but there is no onclick event or easy way to close the tooltip. You have to call the Hide() method somewhere else in your code and I would rather have the tooltip be able to close itself. I know there are several balloon tooltips around the net that use manage and unmanaged code to perform this with the windows API, but I would rather stay in my comfy .NET world. I have a thrid party application that calls my .NET application and it has crashes when trying to display unmanaged tooltips.</p>

<p>where <code>obj</code> is some object.</p>
<p>The problem is some of the properties I want aren't in <code>obj.GetType()</code> they're in one of the base classes further up. If I stop the debugger and look at obj, the I have to dig through a few "base" entries to see the properties I want to get at. Is there some binding flag I can set to have it return those or do I have to recursively dig through the <code>Type.BaseType</code> hierarchy and do <code>GetProperties</code> on all of them?</p>

<p>Lately I've been using XPathDocument and XNavigator to parse an XML file for a given XPath and attribute. It's been working very well, when I know in advance what the XPath is. </p>
<p>Sometimes though, the XPath will be one of several possible XPath values, and I'd like to be able to test whether or not a given XPath exists. </p>
<p>In case I'm getting the nomenclature wrong, here's what I'm calling an XPath - given this XML blob:</p>
<pre><code><foo>
<bar baz="This is the value of the attribute named baz">
</foo>
</code></pre>
<p>I might be looking for what I'm calling an XPath of "//foo/bar" and then reading the attribute "baz" to get the value. </p>
<p>Example of the code that I use to do this: </p>
<pre><code>XPathDocument document = new XPathDocument(filename);
XPathNavigator navigator = document.CreateNavigator();
XPathNavigator node = navigator.SelectSingleNode("//foo/bar");
if(node.HasAttributes)
{
Console.WriteLine(node.GetAttribute("baz", string.Empty));
}
</code></pre>
<p>Now, if the call to navigator.SelectSingleNode fails, it will return a NullReferenceException or an XPathException. I can catch both of those and refactor the above into a test to see whether or not a given XPath returns an exception, but I was wondering whether there was a better way? </p>
<p>I didn't see anything obvious in the Intellisense. XPathNavigator has .HasAttributes and .HasChildren but short of iterating through the path one node at a time, I don't see anything nicer to use. </p>

<p>I'm making a shell script to find bigrams, which works, sort of.</p>
<pre><code>#tokenise words
tr -sc 'a-zA-z0-9.' '\012' < $1 > out1
#create 2nd list offset by 1 word
tail -n+2 out1 > out2
#paste list together
paste out1 out2
#clean up
rm out1 out2
</code></pre>
<p>The only problem is that it pairs words from the end and start of the previous sentence.</p>
<p>eg for the two sentences 'hello world.' and 'foo bar.' i'll get a line with ' world. foo'. Would it be possible to filter these out with grep or something?</p>
<p>I know i can find all bigrams containing a full stop with grep [.] but that also finds the legitimate bigrams.</p>

<p>Is it possible in .NET to ascertain whether my application is closing due to Windows being given a shutdown command (as opposed to any old application closing) in order to either write out some temporary cache files or even block the shutdown long enough to prompt for user input?</p>
<p>Whilst my current scope involves a Winform app and a windows service, I am interested in understanding this in a generic way if possible</p>

<p>I'm looking for a code library that converts ANSI escape sequences into HTML color, via plain tags or CSS. For example, something that would convert this:</p>
<pre>ESC[00mESC[01;34mbinESC[00m
ESC[01;34mcodeESC[00m
ESC[01;31mdropbox-lnx.x86-0.6.404.tar.gzESC[00m
ESC[00mfooESC[00m</pre>
<p>Into this:</p>
<pre><code><span style="color:blue">bin</span>
<span style="color:blue">code</span>
<span style="color:red">dropbox-lnx.x86-0.6.404.tar.gz</span>
foo
</code></pre>
<p>Converting breaks into <br/> isn't necessary, it's just the escape codes that I don't know. I could hack it together myself, but I'd probably miss something important like underlines or mess up how background colors work. I'd rather just sit on top of someone else's code.</p>
<p>Does such a tool (command line linux) or library (perl, python, or ruby preferably) exist?</p>

<p>I need to set the onload attribute for a newly popped-up window.
The following code works for Firefox:</p>
<pre><code><a onclick="printwindow=window.open('www.google.com');printwindow.document.body.onload=self.print();return false;" href='www.google.com'>
</code></pre>
<p>However, when I try this in IE, I get an error - "printwindow.document.body null or not defined'</p>
<p>The goal is to pop open a new window, and call up the print dialog for that window once it's been opened. </p>
<p>Any clues on how to make this work?
It is important not to use javascript elsewhere on the target page, as I do not have control over it. All functionality must be contained in the link I posted above.</p>

<p>svn:externals can be great for sucking in central libraries or IP into a project, so that they can be kept in one location accessible for all.</p>
<p>But if I'm asking people to external tags of common IP (so it doesn't change on them) it opens the possibility of them inadvertently committing changes to the tag. </p>
<p>How can I make svn:externals read-only? It's acceptable if there is some extra argument or some way of making the external that we can add to the procedure for everyone to follow.</p>

<p>How do I properly convert two columns from SQL (2008) using Linq into a <code>Dictionary</code> (for caching)?</p>
<p>I currently loop through the <code>IQueryable</code> b/c I can't get the <code>ToDictionary</code> method to work. Any ideas?
This works:</p>
<pre><code>var query = from p in db.Table
select p;
Dictionary<string, string> dic = new Dictionary<string, string>();
foreach (var p in query)
{
dic.Add(sub.Key, sub.Value);
}
</code></pre>
<p>What I'd really like to do is something like this, which doesn't seem to work:</p>
<pre><code>var dic = (from p in db.Table
select new {p.Key, p.Value })
.ToDictionary<string, string>(p => p.Key);
</code></pre>
<p>But I get this error:</p>
<blockquote>
<p>Cannot convert from 'System.Linq.IQueryable<AnonymousType#1>' to
'System.Collections.Generic.IEnumerable'</p>
</blockquote>

<p>Etc. which is getting rather ugly as it gets longer and longer ;). Is there a better way to do this ?</p>

<p>How do you go about verifying the type of an uploaded file reliably without using the extension? I'm guessing that you have to examine the header / read some of the bytes, but I really have no idea how to go about it. Im using c# and asp.net.</p>
<p>Thanks for any advice.</p>
<hr>
<p>ok, so from the above links I now know that I am looking for 'ff d8 ff e0' to positively identify a .jpg file for example.</p>
<p>In my code I can read the first twenty bytes no problem:</p>
<pre><code> FileStream fs = File.Open(filePath, FileMode.Open);
Byte[] b = new byte[20];
fs.Read(b, 0, 20);
</code></pre>
<p>so (and please excuse my total inexperience here) but how do I check whether the byte array contains 'ff d8 ff e0'?</p>

<p>When are objects or something else said to be "first-class" in a given programming language, and why? In what way do they differ from languages where they are not?</p>
<p>When one says "everything is an object" (like in Python), do they indeed mean that "everything is first-class"?</p>

<p>Is there a pure-Java equivalent to <jsp:forward page="..." /> that I can use within a <% ... %> block?</p>
<p>For example, I currently have a JSP page something like this:</p>
<pre><code><%
String errorMessage = SomeClass.getInstance().doSomething();
if (errorMessage != null) {
session.setAttribute("error", errorMessage);
%>
<jsp:forward page="error.jsp" />
<%
} else {
String url = response.encodeRedirectURL("index.jsp");
response.sendRedirect(url);
}
%>
</code></pre>
<p>Having to break the <% ... %> block to use the jsp:forward is ugly and makes it harder to read due to indentation, among other things.</p>
<p>So, can I do the forward in the Java code without use the JSP tag?</p>
<p>Something like this would be ideal:</p>
<pre><code><%
String errorMessage = SomeClass.getInstance().doSomething();
if (errorMessage != null) {
session.setAttribute("error", errorMessage);
someObject.forward("error.jsp");
} else {
String url = response.encodeRedirectURL("index.jsp");
response.sendRedirect(url);
}
%>
</code></pre>

<p>I'd like to check ancestry using two jQuery objects. They don't have IDs, and are only going to be available as jQuery objects (or DOM nodes if you called <code>get()</code>). jQuery's <code>is()</code> only works with expressions, so this code would be ideal but will not work:</p>
<pre><code>var someDiv = $('#div');
$('a').click(function() {
if ($(this).parents().is(someDiv)) {
alert('boo');
}
}
</code></pre>
<p>Just want to see if one element is a child of another and I'd like to avoid stepping back into DOM land if possible.</p>

<p>Is there an <strong>efficient</strong> way to create a file with a given size in Java?</p>
<p>In C it can be done with <a href="http://linux.die.net/man/2/ftruncate" rel="noreferrer">ftruncate</a> (see <a href="https://stackoverflow.com/questions/139261/how-to-create-a-file-with-a-given-size-in-linux#245239">that answer</a>). </p>
<p>Most people would just write <strong>n</strong> dummy bytes into the file, but there must be a faster way. I'm thinking of <a href="http://linux.die.net/man/2/ftruncate" rel="noreferrer">ftruncate</a> and also of <a href="http://en.wikipedia.org/wiki/Sparse_file" rel="noreferrer">Sparse files</a>…</p>

<p>I've been running into this problem with Flex for nearly a year, and each time I work up a quick hack solution that works for the time being. I'd like to see if anyone has a better idea.</p>
<p>Here are the conditions of a problem:</p>
<pre><code>|------Container ------------|
| explicitHeight: 400 (or whatever)
| |
| |-------- VBox -------| |
| | percentHeight: 100 | |
| | | |
| | |-Repeater------| | |
| | | Potentially | | |
| | | a lot of stuff. | |
|--|--|---------------|---|---|
</code></pre>
<p>The problem is that, contrary to what I would like to happen, the VBox will ALWAYS expand to accommodate the content inside it, instead of sticking to the explicit height of its parent and creating a scroll bar.</p>
<p>My solution has been to hard code in a reference to the parent (or however far up the display list we need to go to find an explicitly set value as opposed to a percentage).</p>
<p>I've even considered using this in a utility class:</p>
<pre><code>public static function getFirstExplicitHeightInDisplayList(comp:UIComponent):Number{
if (!isNaN(comp.explicitHeight)) return comp.explicitHeight;
if (comp.parent is UIComponent) return
getFirstExplicitHeightInDisplayList(UIComponent(comp.parent));
else return 0;
}
</code></pre>
<p>Please tell me there's a better way.</p>

<p>I feel like I should know this, but I haven't been able to figure it out...</p>
<p>I want to get the name of a method--which happens to be an integration test--from inside it so it can print out some diagnostic text. I can, of course, just hard-code the method's name in the string, but I'd like to make the test a little more DRY if possible.</p>

<p>This one has me scratching my head.</p>
<p>I'm running Subversion 1.3.1 (r19032) on Ubuntu. All was well until recently when I tried to run svnadmin verify prior to a dump. This is the error message:</p>
<blockquote>
<p>svnadmin: Invalid diff stream: insn 0
cannot be decoded</p>
</blockquote>
<p>I have looked around for an explanation and fix but can't seem to find one. Subversion experts, I need your help.</p>

<p>Has anyone else had any problems using google's Domain Tracking API, I am specifically talking about the _link() method.</p>
<p><a href="http://code.google.com/apis/analytics/docs/gaJS/gaJSApiDomainDirectory.html#_gat.GA_Tracker_._link" rel="nofollow noreferrer">The documentation is here</a></p>
<p>The example provided shows that the _link() method should be used in the onclick event like this:</p>
<pre><code><a href="http://www.newsite.com" onclick="pageTracker._link('http://www.newsite.com');return false;">Go to our sister site</a>
</code></pre>
<p>However, this essentially just makes the link...do nothing (most probably because of the 'return false').</p>
<p>My understanding is that the pageTracker._link() method is 'supposed' to add additional parameters to the url and do it's own document.location style redirect.</p>
<p>Any ideas / catches / previous posts??</p>

<p>After reading many of the replies to <a href="https://stackoverflow.com/questions/244302/what-do-you-think-of-the-new-c-40-dynamic-keyword">this thread</a>, I see that many of those who dislike it cite the potential for abuse of the new keyword. My question is, what sort of abuse? How could this be abused so badly as to make people vehemently dislike it? Is it just about purism? Or is there a real pitfall that I'm just not seeing?</p>

<p>I've been working on a SharePoint project and I have gone the route of loading User Controls through a custom web part.</p>
<p>I have several web controls where I need to dynamically generate hyperlinks (in a loop from a database) that will call certain functions of the User Control when clicked.</p>
<p>When I'm building my own ASP.NET sites, I just add parameters to the hyperlink and check on the page load to see if I need to run any other code when a hyperlink is click.</p>
<p>I'm starting to realize that this probably won't be very reliable inside the SharePoint environment because I don't control the way web page URLs are formed.</p>
<p>I would prefer to have it post back when the hyperlink is clicked and pass some values, but I'm not sure the best way to approach this.</p>
<p>Could someone point me in the right direction?</p>
<p>Thanks.</p>

<p>I have a series of text that contains mixed numbers (ie: a whole part and a fractional part). The problem is that the text is full of human-coded sloppiness:</p>
<ol>
<li>The whole part may or may not exist (ex: "10")</li>
<li>The fractional part may or may not exist (ex: "1/3")</li>
<li>The two parts may be separated by spaces and/or a hyphens (ex: "10 1/3", "10-1/3", "10 - 1/3").</li>
<li>The fraction itself may or may not have spaces between the number and the slash (ex: "1 /3", "1/ 3", "1 / 3").</li>
<li>There may be other text after the fraction that needs to be ignored</li>
</ol>
<p>I need a regex that can parse these elements so that I can create a proper number out of this mess.</p>

<p>I have the following intentionally trivial function:</p>
<pre><code>void ReplaceSome(ref string text)
{
StringBuilder sb = new StringBuilder(text);
sb[5] = 'a';
text = sb.ToString();
}
</code></pre>
<p>It appears to be inefficient to convert this to a StringBuilder to index into and replace some of the characters only to copy it back to the ref'd param. Is it possible to index directly into the text param as an L-Value?</p>
<p>Or how else can I improve this?</p>

<p>I'm fairly new to Castle Windsor and am looking into the in's and out's of the logging facility. It seems fairly impressive but the only thing i can't work out is where Windsor sets the Logger property on my classes. As in the following code will set Logger to the nullLogger if the class hasn't been setup yet but when Resolve is finished running the Logger property is set. </p>
<pre><code>private ILogger logger;
public ILogger Logger
{
get
{
if (logger == null)
logger = NullLogger.Instance;
return logger;
}
set { logger = value; }
}
</code></pre>
<p>So what I am wondering is how and where windsor sets my Logger property. </p>
<p>Cheers
Anthony</p>

<p>Is there any way I can detect when my page has been set as the user's homepage in their browser?</p>
<p>I'm most interested in something in javascript, but I'd be happy to hear about other approaches as well.</p>
<p><strong>Edit</strong>: I'm not looking for anything sneaky. I'm wondering if there is anything that is explicitly allowed through the browsers to find out this information.</p>

<p>If I have the following string:</p>
<pre><code>string s = "abcdefghab";
</code></pre>
<p>Then how do I get a string (or char[]) that has just the characters that are repeated in the original string using C# and LINQ. In my example I want to end up with "ab".</p>
<p>Although not necessary, I was trying to do this in a single line of LINQ and had so far come up with:</p>
<pre><code>s.ToCharArray().OrderBy(a => a)...
</code></pre>

<p>What are some of the lesser know, but important and useful features of Windows batch files?</p>
<p>Guidelines:</p>
<ul>
<li>One feature per answer</li>
<li>Give both a short <strong>description</strong> of the feature and an <strong>example</strong>, not just a link to documentation</li>
<li>Limit answers to <strong>native funtionality</strong>, i.e., does not require additional software, like the <em>Windows Resource Kit</em></li>
</ul>
<p>Clarification: We refer here to scripts that are processed by cmd.exe, which is the default on WinNT variants.</p>

<p>I have an ASHX handler that returns an XML response (FileStructureXML.ashx).</p>
<p>Now I need to get the XML response from the ASHX handler and use it as a data source for my ASPX page.</p>
<p>If I point the XMLDataSource to a static XML file on the server, the treeview populates as expected. However, if I point the XMLDataSource to the ASHX handler instead of a static XML file on the server, it doesn't work.</p>
<p>Any help would be appreciated.</p>

<p>Here's the situation - I've got a shell that loads an external .swf. Now, that .swf is 800x600, but it's an animation piece, and there are elements that extends off the stage. When I load the .swf into the shell and call its width attribute, it returns 1200 - because it's including the elements that break out of the stage.</p>
<p>This isn't what I want - ideally, there would be two properties, one to return the 'calculated width' and one to return the 'default width'. Do these properties exist, and if not, what's the best workaround?</p>

<p>I want to add complex databinding to my custom winforms control, so I can do the following:</p>
<pre><code>myControl.DisplayMember = "Name";
myControl.ValueMember = "Name";
myControl.DataSource = new List<someObject>();
</code></pre>
<p>Does anyone know what interfaces, etc. have to be implemented to achieve this?</p>
<p>I have had a look into it and all I found is <code>IBindableComponent</code>, but that seems to be for Simple Binding rather than Complex Binding.</p>

<p>Using Python I want to be able to draw text at different angles using PIL.</p>
<p>For example, imagine you were drawing the number around the face of a clock. The number <strong>3</strong> would appear as expected whereas <strong>12</strong> would we drawn rotated counter-clockwise 90 degrees.</p>
<p>Therefore, I need to be able to draw many different strings at many different angles.</p>

<p>I'm pretty new to the idea of recursion and this is actually my first attempt at writing a recursive method. </p>
<p>I tried to implement a recursive function Max that passes an array, along with a variable that holds the array's size in order to print the largest element. </p>
<p>It works, but it just doesn't <em>feel</em> right!</p>
<p>I have also noticed that I seem to use the static modifier much more than my classmates in general...</p>
<p>Can anybody please provide any general tips as well as feedback as to how I can improve my code?</p>
<pre><code>public class RecursiveTry{
static int[] n = new int[] {1,2,4,3,3,32,100};
static int current = 0;
static int maxValue = 0;
static int SIZE = n.length;
public static void main(String[] args){
System.out.println(Max(n, SIZE));
}
public static int Max(int[] n, int SIZE) {
if(current <= SIZE - 1){
if (maxValue <= n[current]) {
maxValue = n[current];
current++;
Max(n, SIZE);
}
else {
current++;
Max(n, SIZE);
}
}
return maxValue;
}
</code></pre>
<p>}</p>

<p>I'm looking for a way to get the name of the main HTML form so I can submit it from JavaScript.</p>
<p>The reason I can just set the name of the form is because the JavaScript is on a User Control that could get added to many different sites with different form names.</p>
<p>Thanks.</p>

<p>How do you connect to a remote server via IP address in the manner that TOAD, SqlDeveloper, are able to connect to databases with just the ip address, username, SID and password?</p>
<p>Whenever I try to specify and IP address, it seems to be taking it locally.</p>
<p>In other words, how should the string for cx_Oracle.connect() be formatted to a non local database?</p>
<p>There was a previous post which listed as an answer connecting to Oracle via cx_Oracle module with the following code:</p>
<pre><code>#!/usr/bin/python
import cx_Oracle
connstr='scott/tiger'
conn = cx_Oracle.connect(connstr)
curs = conn.cursor()
curs.execute('select * from emp')
print curs.description
for row in curs:
print row
conn.close()
</code></pre>

<p>Having a vector containing pointers to objects then using the clear function doesn't call the destructors for the objects in the vector. I made a function to do this manually but I don't know how to make this a generic function for any kind of objects that might be in the vector.</p>
<pre><code>void buttonVectorCleanup(vector<Button *> dVector){
Button* tmpClass;
for(int i = 0; i < (int)dVector.size(); i++){
tmpClass = dVector[i];
delete tmpClass;
}
}
</code></pre>
<p>This is the function I have that works fine for a specific type of object in the vector but I'd like a single function that could take any kind of vector with object pointers.</p>
