This link is very good for C#, what about java. I serach but i did not find good solution.
I have an application where I need to check for a file which may be created dynamically during my execution, I will give up after some MAX time where the file has yet to show up. I wanted to know if there was a more efficient method in Java of checking for the file other than polling for it and then sleeping every X seconds? If not what would be the most efficient manner of doing this?
I want to execute a powershell using the .net Powershell SDK. I have this working fine.
Before I execute it I want to check that the script has been signed by my code signing certificate - this is easy enough to do from within powershell itself using Get-AuthenticodeSignature but I would like to do this in code before choosing to execute this script.
I have several select boxes and textboxes with the same class and I have the following statement.
if ($('.selTxtClass:visible').val() == "") {
$('.selTxtClass:visible').focus();
}
}
If I do an alert with ($('.selTxtClass:visible').val()) it comes as undefined.
I want to check that the value of these elements are empty, but I cant see what is wrong with this if statement, could you give me a hand, please?
Thanks a lot.

In javascript, how would you check if an object is actually visible. I don't just mean checking the visibility and display attributes. I mean, checking that the element is not
visibility:hidden or display:none
underneath another element
scrolled off the edge of the screen.
EDIT: For technical reasons, I can't include any scripts. I can however use prototype as it is on the page already.
EDIT 2: This is no longer neccesary, but I'd still find an answer interesting)

Working with an standard configuration of the server, without any lock, my files are read-only after every check out or update to the working copy. I have to set them to be not read-only to continue working, but besides this shouldn't be happening, it's uncomfortable.
Anybody knows how to avoid this behavior?

I'm aware that Perl has some nice modules to deal with Excel files so the idea is to, let's say, run that check daily, perhaps with cron, and write the result on a spreadsheet for further statistical use.

Is there one?
hi,
I'm trying to check if a given URL is valid and i'm doing it like this:
- (BOOL)urlIsValid:(NSString *)address {
NSURL *testURL = [NSURL URLWithString:address];
if (testURL == nil) {
return NO;
}
else {
return YES;
}
}
Since "URLWithString" is supposed to return "nil" if the URL is malformed I thought this would work but it doesn't for some reason. Could someone please tell me why?
Thanks in advance!

In vb.net how do you check if a ANY directory exists inside a directory

What is the fastest way to create a hash function which will be used to check if two files are equal?
Security is not very important.
Edit: I am sending a file over a network connection, and will be sure that the file on both sides are equal
while the application is running i'm using FileSystemWatcher to monitor the folder. But what if there are changes to the folder when the application is not running, how can I check for these changes when the application starts.
(similar to how windows media player, for example, monitors your music folder. Even when you add songs to that folder when it is not running, it does discover them when it runs next time)
Thanks
I have the following dictionary:
sites = {
'stackoverflow': 1,
'superuser': 2,
'meta': 3,
'serverfault': 4,
'mathoverflow': 5
}
To check if there are more than one key available in the above dictionary, I will do something like:
'stackoverflow' in sites and 'serverfault' in sites
The above is maintainable with only 2 key lookups. Is there a better way to handle checking a large number of keys in a very big dictionary?
