<a href="javascript:window.opener='x';window.close();">Close</a>
You need to set window.opener to something, otherswise it complains. |
use windows installer properties. will probably be easier.
<http://msdn.microsoft.com/en-us/library/aa370905(VS.85).aspx#system_folder_properties> |
The browser is complaining because you're using JavaScript to close a window that wasn't opened with JavaScript, i.e. `window.open('foo.html');`. |
You should probably use API for this, such as [SHGetFolderPath][1]

Check the Debug tab on your project's properties page. There should be an "Enable unmanaged code debugging" checkbox. This worked for me when we developed a new .NET UI for our old c++ DLLs.

I agree with John Millikin. You can add in `<span>` tags or something around each line with a CSS class defined, then make them display:block if necessary. The only other way I can think to do this is to make the `<input>` an inline-block and make them emit "very large" padding-right, which would make the inline conten... |
String concatenation is slow, because it creates multiple `String` objects under the hood. When you need to concatenate many strings, you'd better use a `StringBuffer`. |
One shouldn't be faster than the other. Some people believe that string concatenation is slow in Java, because it would create multiple `String` objects "under the hood". However, as the [JavaDoc for StringBuffer][1] states, at least since Java 5 using the "+" operator boils down to creating a `StringBuffer` and `appen... |
One shouldn't be faster than the other. This wasn't true before Java 1.4.2, because when concatenating more than two strings using the "+" operator, intermediate `String` objects would be created during the process of building the final string.

Huh? I guess, I don't get the question?
Can't you just end your pipe into a `>> ~file`
For example
echo "Foobar" >> /home/mo/dumpfile
will append Foobar to the dumpfile (and create dumpfile if necessary). No need for a shell script... Is that what you were looking for? |
If you want to analyze it in the script:
while /bin/true; do
read LINE
echo $LINE > $OUTPUT
done
But you can simply use cat. If cat gets something on the stdin, it will echo it to the stdout, so you'll have to pipe it to cat >$OUTPUT. These will do the same. The second works for binary ... |

SOAP itself is actually pretty basic and simple, it's the WSS-* standards on top of it that make it very complex.

If the compiler doesn't support 64 bit enums by compilation flags or any other means I think there is no solution to this one.

A CDATA section is required if you are using XHTML in order for it to validate, as XHTML will parse the JavaScript code as parsed character data as opposed to character data by default.

Java applet cached forever, not downloading new version? |

We have a case where clients seem to be eternally caching versions of applets. We're making use of the `<param name="cache_version">` tag correctly within our `<object>` tag, or so we think.

It sort of depends on what you're trying to do.

A logical way to think about this is:
1. Code placed in a finally block must be executed **whatever occurs** within the try block

In this new light, I'm pretty sure that you do not want to force anyone to override Clone() at all. For example, if my derived class does not add any fields it probably does not need its own specialized Clone() method. |

If exim or sendmail is what's writing into the pipe, then procmail is a good answer because it'll give you file locking/serialization and you can put it all in the same file.
If you just want to write into a file, then

or
- cat > /tmp/log.$$
might be good enough. |
Cache... hard. Record hits, and if a spike occurs, write out a completely static copy of the page being hit, then serve that.
