In 2016, what is the correct way to create a commercial MS Office Add In? : <p>I've been writing VB6 code for Outlook and Excel for at least 10 years, but it's generally written in the VB Editor and saved as the default project or a worksheet module, therefore not very portable.</p>
<p>I'm at the stage now where I want to switch to .net and write proper add-ins, that I can distribute and potentially sell (so would need to be protected and installable).</p>
<p>However, there seems to be a lot of conflicting advice out there about how to do this, and what software to use.</p>
<p>I'd really like to know the definitive way to do this in 2016;</p>
<ul>
<li>What software to use (I presume, either the paid or free version of VS)</li>
<li>What language to use (I assume a flavour of .net)</li>
<li>What I need to do to be able to distribute or sell the addin (do they still need to be signed?)</li>
<li>any advice on definitive resources to make the switch from hacker-style projects to stand alone projects</li>
</ul>
<p>Apologies if this sounds vague, or isn't the correct format for SO; I'm a web developer, mainly open source technologies, so the MS stack (Office aside) has always been a different world for me.</p>
<p>Thanks,
Dave</p>

Setting NODE_ENV for firebase function : <p>I am moving some of my <code>firebase-queue</code> workers to Firebase Functions. I have used <code>process.env.NODE_ENV</code> to set some of the configuration for the workers depending on the environment in which I am running them. Is there a way to set the <code>NODE_ENV</code> for the functions while deploying them. I understand that the recommended way to provide such config options is via <code>firebase.config.set</code> which I have verified works as expected but just wanted to check if there is a way to set the <code>NODE_ENV</code> also. When I try to print out the <code>NODE_ENV</code> inside of a function, it is always set to <code>production</code>.</p>

Could someone explain this code for me please : <p>I found this Caesar cipher encryption code on the web and I'm trying to understand how it works </p>
<pre><code>#include<stdio.h>
int main()
{
char message[100], ch;
int i, key;
printf("Enter a message to encrypt: ");
gets(message);
printf("Enter key: ");
scanf("%d", &key);
for(i = 0; message[i] != '\0'; ++i){
ch = message[i];
if(ch >= 'a' && ch <= 'z'){
ch = ch + key;
if(ch > 'z'){
ch = ch - 'z' + 'a' - 1;
}
message[i] = ch;
}
else if(ch >= 'A' && ch <= 'Z'){
ch = ch + key;
if(ch > 'Z'){
ch = ch - 'Z' + 'A' - 1;
}
message[i] = ch;
}
}
printf("Encrypted message: %s", message);
return 0;
}
</code></pre>
<ul>
<li><p>Meaning of <code>if(ch >= 'a' && ch <= 'z')</code>
Like does c include the alphabet as an array or something or how does it know that the letter is b or others ?</p></li>
<li><p>Adding an int to a char in <code>ch = ch + key;</code></p></li>
<li><p>this math thing <code>ch = ch - 'Z' + 'A' - 1;</code></p></li>

What is the point of having resolved URL in package-lock.json? : <p>whenever I generate a package-lock file, there is also "resolved" block that looks like this:</p>
<pre><code>"resolved": "http://devel.npm.registry:4873/lodash/-/lodash-4.17.5.tgz"
</code></pre>
<p>What is the point of this URL? Later, if I try to install dependencies based on this package-lock, do I need to use the same npm registry? Because we use a different npm registry for local development and for production builds. Thus when I develop, I use <code>devel.npm.registry</code>, but the CI tool uses <code>production.npm.registry</code>. According to my tests, the URL doesn't matter (I tried <code>npm@6.4.1</code>). But it is current implementation that's gonna change soon or is the URL intentionally ignored? I have the feeling that some of the previous versions of npm actually checked the resolved URLs. </p>
<p>The <a href="https://docs.npmjs.com/files/package-lock.json#resolved" rel="noreferrer">documentation</a> isn't much helpful in this case.</p>

word-wrap: break-word;
overflow: hidden;

line-height: 1.2em;
text-align:justify;
}
.text.ellipsis::after {
content: "...";
position: absolute;
right: -12px;
bottom: 5px;
}
</code></pre>
<p>because I need to have multy-line ellipse for titles. And this part of code works.</p>
<p>but now I need to center vertically div inside div, and this part of code works partially.... I really tried everything but still cant fix the problem.</p>
<p>you can see here the live example: <a href="http://phpbb32.majordroid.com/index.php" rel="nofollow noreferrer">http://phpbb32.majordroid.com/index.php</a></p>
<p>Inside the blue div everything is fine, but below inside white div title for some reason sank, or in other words is not centered.</p>
<p>So I hope you can help me to center vertically div inside div, and it needs to work in IE8+</p>

Cannot find var in python : <p>At the beginning of my program, I am defining a simple object which sets the configuration for how I am going to call a service. Like so : </p>

password='xxx',
version='2016-05-31')
</code></pre>
<p>I then want to call a service on all files in a directory. I try to do it like so, but I believe the config object cannot be found - it seems to be out of scope, I get this error: </p>
<pre><code>NameError: name 'config' is not defined
</code></pre>
<p>Here is what I have directly after the object creation : </p>
<pre><code>yourpath = 'C:\\Users\\Desktop\\working_folder\\'
for root, dirs, files in os.walk(yourpath, topdown=False):
for name in files:
print(os.path.join(root, name))
config['conversion_target'] = DocumentConversionV1.ANSWER_UNITS
with open(join(dirname(__file__), os.path.join(root, name)), 'r') as document:
print(json.dumps(document_conversion.convert_document(document=document, config=config), indent=2))
</code></pre>
<p>I've tried defining the config object within the for loop/within the with clause, but it still seems to not work. Curiously, if I remove the for loop from the above, it does seem to work (if ran on one file, rather than a folder).</p>
<p>Any ideas what could be the problem here ?</p>

button [] [] to node -- java : I'll keep it quick. I'm trying to create a standard calculator. I want to use a BorderPane so I can keep my display:

pane.setTop(display); however I am using an array:
I then would want to use an array of buttons as a single object to place in the center of the pane.
Button [][] keys = new Button [a][b];
pane.setCenter(keys);
however I get an error: Button [][] cannot be converted to Node. I would like to know if there is anyway I can parse the elements to become/assume the value of a Node or if i can create a method to do so.
Appreciate the help, thanks!

<p>The output is: a b a b b c d b d c b b b b</p>
<p>In Node.js v8.6.0 the following code starts displaying "c" before displaying "a" is finished.</p>
<pre><code>const asyncfunc = (message, n) => {
for (let i = 0; i < n; ++i) {
setTimeout(() => {
console.log(message);

}
async function main() {

const b = asyncfunc("b", 8);
await a;
const c = asyncfunc("c", 2);
const d = asyncfunc("d", 2);
await c;
await d;
await b;
}
main();
</code></pre>
<p>The output is: a b c d a b c d b b b b b b</p>
<p>Is there any handy ways in Node.js to write the above C++ code equivalent?</p>

Isolated styled-components with @font-face : <p>I'm using <a href="https://github.com/styled-components/styled-components" rel="noreferrer">https://github.com/styled-components/styled-components</a>. </p>
<p>I'm trying to work out the best strategy for components that require <code>@font-face</code>. I want to make sure each component is independent of its context, so I'm defining <code>font-family</code> styles on each them. But if I use <code>injectGlobal</code> in multiple components, I get multiple <code>@font-face</code> rules for the same font.</p>
<p>Should I just define the <code>@font-face</code> rules in my <code>ThemeProvider</code> entry-point component and live with the fact that the desired font might not be loaded by the browser?</p>

Swift: create object from primitive value : <p>I'm not entirely sure that what I want to do is possible to implement currently, however I hope that it is.<br>
Basically, I would like to have some mechanism for a bit shorter object creation for primitive. Let me explain. Consider we have some kind of wrapper around Int:</p>
<pre><code>class Wrapper {
var value: Int = 0
init(value: Int) {
self.value = value
}
}
</code></pre>
<p>And then instead of creating object with init, i.e:</p>
<pre><code>let wrapper = Wrapper(value: -1)
</code></pre>
<p>I would like to do something like this:</p>
<pre><code>let wrapper: Wrapper = -1
</code></pre>
<p>Or:</p>
<pre><code>var array = [Wrapper]()
array.append(-1)
</code></pre>
<p>It would short declarations quite heavily, especially in case with arrays.<br>
Interesting note: I've tested code above with CGFloat i.e:</p>
<pre><code>let val: CGFloat = 0.0
var array = [CGFloat]()
array.append(0.0)
</code></pre>
<p>and all seems to be working fine. However I'm not entirely sure that there is way in language that allow to create such behaviour for custom object and it's why I'm asking about it basically. I've reviewed sources of CGFloat, but didn't saw anything that seems to be related to functionality that i want to achieve (beside NativeType alias may be, but I didn't understand how it would work).</p>

Function for matrix in R : <p>I'm new (very new) in R. I'm struggling with making a function that's supposed to take a matrix (old_matrix) and return a new matrix (new_matrix), but in new_matrix all values in old_matrix that is a prime should be multiplied by 2 when it appears in new_matrix. So the new matrix should look the same as the old matrix, but where a prime occurs in old, this element should be multiplied by 2. </p>
<p>I'm thinking that I should start out with a for loop, but I'm already struggling with how to make the loop go through all elements of the matrix. I appreciate all the help I can get to get closer to making this function!</p>

Running bash scripts with npm : <p>I want to try using npm to run my various build tasks for a web application. I know I can do this by adding a <code>scripts</code> field to my <code>package.json</code> like so:</p>

},
</code></pre>
<p>This gets unwieldy when you have more complex commands with a bunch of options. Is it possible to move these commands to a bash script or something along those lines? Something like:</p>
<pre><code>"scripts": {
"build": "build.sh"
},
</code></pre>
<p>where <code>npm run build</code> would execute the commands in the <code>build.sh</code> file?</p>

What are some ways to figure out related products/questions/items anything? : <p>What are some ways including machine learning that I can use in my projects to generate things related to another. Like related apps, related websites, related products, etc.</p>
<p>I've been brainstorming these are strategies...</p>
<p>one way i can think of is show items from same category. But that would be too broad.</p>
<p>2nd way improves upon previous step, it's to keep track of what people click next and promote that item. Meanwhile keep bottom list randomized to let other relevant items show up and get clicked. </p>
<p>3rd way is to use machine learning and provide training data somehow and use that.</p>
<p>I want something simple but smart, as it gets better with time. </p>

What's the difference between uWSGI's socket-timeout/http-timeout/harakiri? : <p>I wrote a simple WSGI application (using Flask) served by uWSGI (i.e. no other HTTP server but uWSGI) which only supports a single PUT route using which clients can upload a file (potentially ~400MB in size), have it processed on the server and then sent back.</p>
<p>In the uWSGI logs, I noticed two kinds of timeout errors after some time. Usually it's a timeout when sending the response:</p>
<pre><code>Feb 02 20:46:30 myserv uwsgi[18948]: uwsgi_response_sendfile_do() TIMEOUT !!!
Feb 02 20:46:30 myserv uwsgi[18948]: OSError: write error
Feb 02 20:46:30 myserv uwsgi[18948]: [pid: 18954|app: 0|req: 1795/3935] aa.bb.cc.dd () {32 vars in 455 bytes} [Fri Feb 2 20:46:06 2018] PUT /sample.exe => generated 0 bytes in 24314 msecs via sendfile() (HTTP/1.1 200) 6 headers in 258 bytes (3353 switches on core 0)
</code></pre>
<p>Sometimes though, it's also a timeout when receiving a PUT request:</p>
<pre><code>Feb 03 20:18:32 signserv uwsgi[18948]: [pid: 18953|app: 0|req: 2975/5670] aa.bb.cc.dd () {32 vars in 455 bytes} [Sat Feb 3 20:18:02 2018] PUT /samplefile.exe => generated 0 bytes in 29499 msecs via sendfile() (HTTP/1.1 200) 6 headers in 258 bytes (2930 switches on core 0)
Feb 03 20:20:30 signserv uwsgi[18948]: [uwsgi-body-read] Timeout reading 16384 bytes. Content-Length: 354414781 consumed: 0 left: 354414781
</code></pre>
<p>Some debugging suggests that this typically happens with clients which are very slow (i.e. which have a high load).</p>
<p>I'd like to alleviate this by increasing some timeouts, but uWSGI appears to support a plethora of timeouts and it's not clear to me which of them are relevant here. I identified three timeouts which sound like I may want to increase them, but I have trouble finding documentation on how they differ:</p>
<ul>
<li><code>socket-timeout</code></li>
<li><code>http-timeout</code></li>
<li><code>harakiri</code></li>
</ul>
<p>Can anyone shed some light on what these timeouts affect, what their default values are and which (if any) of them should be adjusted to avoid above-mentioned issues?</p>

How does sql server system check duplicates? : I definitely know how to check duplicates/remove duplicates using sql server queries. But I am asking a deeper question about the system. How does the system handle duplicates? For example, how does the system remove duplicates from UNION ALL to UNION? I am guessing if the system is using hash code to do so? The employer said the process has something to do with ROWID. But even if two rows are exactly the same, their ROWID should be different, correct? How is that possible?

Use of colon in variable declaration : <p>I was asked recently what this means in python:</p>
<p><code>>>> char : str</code></p>
<p>I had no idea. I'd never seen that before. I checked the docs and there isn't anything like that. One person's suggestion was that it is static type declaration, but there is absolutely nothing in the docs about that either. </p>
<p>With the above, if I
<code>>>> type(char)</code> it fails</p>
<p>If I <code>>>> char : str = 'abc'</code> it works, and the results of type(char) is <code><class: str></code>. It can't be static declaration though, because I can <code>>>> char : str = 4</code> and type(char) becomes <code><class: int></code>.</p>
<p>So I come here to collect the wisdom of the many SO overlords. What does that mean?</p>

</ul>
<p>Add the following to <code>dependencies</code> in project.json:</p>
<pre><code>"ClassLibrary1": {
"version": "*",
"target": "project"
}
</code></pre>
<h2>Issue</h2>
<p>Why can I not add <code>"target":"project"</code> to my dependencies when specifying a project dependency?</p>

<h2>My Question</h2>
<p><strong>How do I add a project reference to my regular class library from an ASP.NET Core RC2 web project?</strong></p>

White label fonts in iOS application : <p>My task is to white label iOS application.</p>
<p>I've done a lot of things for Assets and for Info.plist, I just left to manage a white-label solution for the <strong>fonts</strong>.</p>
<p>For example, Every customer wants to have their fonts for titles. So I got in my mind some solutions.</p>
<blockquote>
<p>1) There will be some Config files we can write customers fonts in the
config file and when Application will run I will read font from that
config file and apply them but didn't know how to to that on every
screen dynamically.</p>
<p>2) Create some base ViewController class and apply here fonts, then
every viewController class will be the child of that base class and
apply view controllers specific title fonts to my base fonts.</p>
</blockquote>
<p>I don't know if those solutions are good and the reason for this question is to get some advice and some better solutions. </p>
<p>Maybe someone is more experienced than me and maybe someone has a better idea than me. Every single advice and help will be very valuable for me.</p>
<p>Thank you.</p>

How to strip value from array returned by google sheets : I am using PHP to read and write to goolge sheets using the goolge API. When I use this command $my_variable=$service->spreadsheets_values->get($spreadsheetId,$range); google sheets returns an array that looks like this object(Google_Service_Sheets_ValueRange)#44 (7) { ["collection_key":protected]=> string(6) "values" ["majorDimension"]=> string(4) "ROWS" ["range"]=> string(9) "Sheet1!A4" ["values"]=> array(1) { [0]=> array(1) { [0]=> string(3) "180" } } ["internal_gapi_mappings":protected]=> array(0) { } ["modelData":protected]=> array(0) { } ["processed":protected]=> array(0) { } }
The number I want is in the array, it's the answer (output from spreadsheet) which in this case is 180. What PHP command can I use to pluck that value from the array and echo or print it to the screen?

ng command throws error; @angular-devkit/core seems to be missing : <p>I'm a little new to Angular, so apologies if this question has been asked many times. Certainly, I have found MANY github issues with similar symptoms, but no clear solution (or it's a problem that keeps coming back).</p>
<h2>PROBLEM:</h2>
<p>I installed whatever the latest version of Angular comes from npm:</p>
<p><code>npm install -g @angular/cli</code></p>
<p>When I run <code>ng</code> (with any options, even if just <code>ng --version</code>), I get the following error:</p>
<pre><code>module.js:540
throw err;
^
Error: Cannot find module '@angular-devkit/core'
at Function.Module._resolveFilename (module.js:538:15)
...
...
</code></pre>
<h2>APPARENT SOLUTION:</h2>
<p>Installing <code>@angular-devkit/core</code> seems to fix the problem:</p>
<p><code>npm install -g @angular-devkit/core</code></p>
<p>... well, almost...</p>
<p>I then have to make sure I ALSO install the same devkit component <strong>for each application</strong>:</p>
<p><code>npm install --save @angular-devkit/core</code></p>
<h2>QUESTIONS:</h2>
<p>Is there a problem with Angular's packaging?</p>
<p>Do they deliberately leave out the devkit/core component, or just an accident with some versions?</p>
<p>OR, Could it be that I am doing something wrong?</p>
<hr>
<p><strong>SOFTWARE VERSIONS:</strong></p>
<ul>
<li>Angular CLI: 1.6.4</li>
<li>Node: 8.9.4</li>
<li>OS: linux x64</li>
<li>Angular: 5.2.1</li>

Sort a vector by specific member C++ : <p>Is it possible to sort a <code>vector</code> by a specific member of it's class? </p>

int getPositionX() const;
int getPlace() const;};
</code></pre>
<p>And a vector of cars: <code>vector<Car*> raceTrack;</code></p>
<p>What I want to do is sort this vector according to car's position. If the car A is ahead of car B then A takes 1st place and B takes 2nd place, and so on.</p>
<p>P.S. Imagine that all the cars have already a place defined (ex: car A has 1, car B has 2, car C has 3...)</p>

Why do lifetimes differ when a function is called in a closure vs. being called directly in Rust? : <p>In the following code example:</p>
<pre><code>fn default_values() -> &'static [u32] {
static VALUES: [u32; 3] = [1, 2, 3];
&VALUES
}
fn main() {
let values: [u32; 3] = [4, 5, 6];
let optional_values: Option<&[u32]> = Some(&values);
// this compiles and runs fine
let _v = optional_values.unwrap_or_else(|| default_values());
// this fails to compile
let _v = optional_values.unwrap_or_else(default_values);
}
</code></pre>
<p>the last statement fails to compile with:</p>
<pre><code>error[E0597]: `values` does not live long enough
--> src/main.rs:8:49
|
8 | let optional_values: Option<&[u32]> = Some(&values);
| ^^^^^^ borrowed value does not live long enough
...
12 | }
| - borrowed value only lives until here
|
= note: borrowed value must be valid for the static lifetime...
</code></pre>
<p>I'm wondering:</p>
<ol>
<li>what's happening that causes the difference in behaviour between the last two statements</li>
<li>whether the first <code>unwrap_or_else(|| default_values())</code> is the correct way of handling this, or whether there's a better pattern</li>
</ol>

<p>Line 2068 is this:</p>
<pre><code>if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
</code></pre>
<p>I believe it's claiming <code>grantResults</code> length is zero which is why the java.lang.ArrayIndexOutOfBoundsException is thrown. According to the <a href="https://developer.android.com/reference/android/support/v4/app/ActivityCompat.OnRequestPermissionsResultCallback.html" rel="noreferrer">documentation</a> </p>
<blockquote>
<p>int: The grant results for the corresponding permissions which is
either <strong>PERMISSION_GRANTED or PERMISSION_DENIED. Never null.</strong></p>
</blockquote>
<p><code>grantResults</code> will not be null, but doesn't say anything about it not containing a value either. Furthermore it seems like the callback will contain at least one value, either <code>PERMISSION_GRANTED</code> or <code>PERMISSION_DENIED</code>. Is this a bug or am I misunderstanding the documentation?</p>

Sqlite: fetching fisrt char from the word and replace with * based on any condition : I need to fetch first char of contact names (includes all language) and replace chars which doesn't satisfy range of char-set for selected language.
For example:- My table will be having English contacts and Chinese contacts, now if I select Chinese language then my query should give me all the first chars from the names but for English contact it should return '*'.
Any lead will be appreciated.
Thanks in advance.

How can I flatten an array swiftily in Swift? : <p>I want to turn this:</p>
<pre><code>let x = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
</code></pre>
<p>into this:</p>
<pre><code>[1, 2, 3, 4, 5, 6, 7, 8, 9]
</code></pre>
<p>very gracefully.</p>
<p>The most straightforward way, of course, is</p>
<pre><code>var y = [Int]()
x.forEach { y.appendContentsOf($0) }
</code></pre>
<p>But that makes the resulting array mutable, which is unnecessary. I don't like this way.</p>
<p>I tried using <code>reduce</code>:</p>
<pre><code>let y = x.reduce([Int]()) { (array, ints) -> [Int] in
array.appendContentsOf(ints)
return array
}
</code></pre>
<p>But the compiler complains that <code>array</code> is immutable, so I can't call the mutating method <code>appendContentsOf</code>. </p>
<p>Hence, I added some stuff:</p>
<pre><code>let y = x.reduce([Int]()) { (array, ints) -> [Int] in
var newArr = array
newArr.appendContentsOf(ints)
return newArr
}
</code></pre>
<p>This is just <em>plain bad</em>. I have an instinct that this is not swifty.</p>
<p>How can I flatten an array more swiftily than the above methods? A one-liner would be good.</p>

c++ employee name search : <pre><code> string name[size] = {"Collins, Bill", "Smith, Bart", "Michalski, Joe", "Griffin, Jim",
"Sanchez, Manny", "Rubin, Sarah", "Taylor, Tyrone", "Johnson, Jill",
"Allison, Jeff", "Moreno, Juan", "Wolfe, Bill", "Whitman, Jean",
"Moretti, Bella", "Wu, Hong", "Patel, Renee", "Harrison, Rose",
"Smith, Cathy", "Conroy, Pat", "Kelly, Sean", "Holland, Beth"};
int binarySearchIterative(string name[], int size, string empName) {
int low = 0;
int high = size - 1;
while (low <= high) {
int mid = (low + high) / 2;
if (empName == name[mid]) {
return mid;
} else if (empName < name[mid]) {
high = mid - 1;
} else {
low = mid + 1;
}
}
return -1;
}
</code></pre>
<p>So when I type in a name to search for, I have to type it in exactly as listed in the array. For example, if I want to find Bill Collins. I have to type it as Collins, Bill. If I were to type in Bill Collins, it would tell me that the employee is not found. I need to be able to search the name First Last, and also without using the comma. If you need to see more of my code let me know.</p>

add subquery to cte : declare @nodeid int = '1';
with cte as (
select cust_ID, name,null lnode, null rnode from user_detail where
cust_ID = @nodeid
union all select t.cust_ID,t.name, ISNULL(cte.lnode, CASE WHEN t.joinside =
0 THEN 1 ELSE 0 END)
lnode, ISNULL(cte.rnode, CASE WHEN t.joinside = 1 THEN 1 ELSE 0 END)
rnode from user_detail t inner join cte on cte.cust_ID = t.parentid )
select cust_ID,name from cte where rnode='0' option (maxrecursion 0)
**Current Scenario:** [screenshot of above query results][1]
**What i want is:**
[screenshot of what i want][2]
***now i will explain what i want:***
the above query is getting results only from user_detail table. now i want to modify the query in such a way that it will also search in "installments" table for the "status" column of the respective cust_id (which the above query is returning).
The modified query will get the value of status from installments table based on cust_id.
And query will show the results in the third column as showing in 2nd screenshot.
i am not much familiar with cte and nested queries. I hope you guys will understand my problem.
