I know that to start a program at startup, we should add this subkey
"C:Program Files<myprogram's path><nameoftheprog>.exe"
to
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionRun
Alright!
But the problem is when my program has to delete a certain file in C:/ at startup, it just can't because it's not ran as administrator!
We create a window service that will launch multiple process of an application with different configuration. And application further communicate with sql server. It works fine when we start service manually from service manager. It launch all the process ( try with launching 3 process ). But when we test it by restart the machine and service launch automatically then it launch only one process third one. I check the event log in event viewer. I see the following message by MSSQL$MSSQLEXPRESS service
Login failed for user 'dduser'. Reason: Failed to open the explicitly specified database. [CLIENT: <local machine>]
one thing we also tried by delaying ( with thread sleep ) the code execution of service. Then by starting machine again , it launch 2 process , first one still not launch.
I 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)?

i am trying to make my own user authentication system after i log on with the windows authentication. I want the program to automatically start on startup and i want to enable:

NoSetFolders : Removes folders from the Settings option on Start Menu
NoSetTaskbar : Removes taskbar settings

Because i dont want someone else to just delete or tamper with the files that my program made to authenticate me. After i enter my credentials in my program and they are correct i want to disable these. I am using Visual Basic 2010 Express and my computer is Windows 7 64 Bit Home Premium.
I know this has been asked previously, but I can't seem to find an answer that fits what I'm looking for.
Need to have a timer reset and start counting down again automatically. I would like to use a loop to do it if possible, as I will be using the loop count later in the program. Here is what I have so far, the counter rolls back to zero but I can't seem to find a way to get it to restart again. For testing I set the time to .1 but it will be set for 2 hours (120) when its working.
[Code]...
The loop sits at 0 like I want until the messagebox comes up and then instead of the process restarting with loop of 1 and counting down, clicking ok on the message box causes the loop to go straight to 5 and the program ends. If I click on the start button again however, everything does restart.

View 1 RepliesI 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.

I'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). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.
I have a WPF app and want to start from Main.xaml which is located in a different assembly. Both assemblies are in the same location.

base.OnStartup(e);

On my program I have a splash screen, which then goes to a form. For some reason, my form (not the splash screen, that's ontop) always starts up behind all the other windows on the screen. Is there a way to fix this, so it starts ontop, but its not always ontop of other windows?

I see it like some kind of public methods that other software can access. Is there any standard approach, best practices or other experience of this?
I guess you could do this with Win32 calls, C/C++ programming etc. But I'm mainly a .NET developer and have some years of experience programmming in mainly VB.NET but also some C#. I hope finding a way to do this within .NET. But it should be accessible for software developed in other languages.

View 5 RepliesI can't find anything about a Visual Basic application that doesn't open with focus I've written an application that takes the current clipboard text and changes all letters to lower case, then the first letter of every word to upper case (the first letter after a space), this is for when I download a file that I want to look neat (such as an mp3 audio file). It's output is then placed in the clipboard to be used as the filename (or text).
I've set a shortcut key (Ctrl+Alt+X) to open the application by placing a shortcut in Accessories so it runs instantly whenever I hit the shortcut combination. However the application steals focus when it runs, so as soon as it ends I lose focus altogether, and I then have to Alt+Tab and find where I was when I used the shortcut! There are 2 possibilities for my application, the latter is what I really want, but the former is OK for me:
1. I use Ctrl+C to copy, The application runs and then switches to the original focus (focus before using my shortcut combination), I can then Ctrl+V to paste.
2. The application runs WITHOUT stealing focus altogether, this way I can have the application copy the selected text for me, and replace it aswel
