C# - Prepend A Substring If The Source String Does Not Begin With The Same Substring?
Oct 10, 2011I'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml
The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.
The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:

View 4 RepliesC# - Detect If Application Start Using A Manual Handling (Pressing An Icon) Or Start When Windows Start?
Feb 28, 2011I have made my application to start automaticly when windows start (registry ../currentversion/run/appname + path). In this mode the application start minimized and an little icon appear in the notification icon area. With this icon you can maximize the app or exit it.If you exit the app and start it again using the Menu (Start/programs etc) than the application start in minimized mode (and in this case I would like to have it in normal mode) because the setting autostart is still true.Is there a way you can detect when the application start when windows startup using the above registry or when people click on an icon in the programs menu (or desktop)?

.net - Why Cancelling 6 WebRequest Using Task.Start Takes Longer That Thread.Start
Jul 24, 2011I have custom asynchronous WebRequest class that I am testing to find out how fast the request will be cancelled and found some odd results, that starting 6 WebRequests with TPL and cancelling them right away takes 25 sec, but when I used just regular background threads it took only 5 sec.
Update: Running them without cancelling takes with Task.Start 9 sec and Thread.Start 3 sec accordingly.

Process.Start To Start An External Command Line Application
Aug 4, 2009I'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine).

No idea why it can't be found, as like I said it executes from the command prompt just fine.
