I have searched this forum, and many sites before. And somehow I couldn't find the correct answer.

The codes I find do not work for me.

And my problem is:

I would like to bring to front/focus an application, that's already running.

For example, notepad, I saw they usually pick it for tutorials like this.

And my situation: I have my form opened, and now I'd like to bring notepad to front.

If someone could stick the code for the example with notepad?

Any help appreciated.

Thank you

Since you are using Visual Basic, there is also the possiblity of calling AppActivate instead of using P/Invoke.

http://msdn.microsoft.com/en-us/library/dyz95fhy.aspx

All you need is to call this,if you are using VB.Net

AppActivate("Untitled - Notepad")

This will set the running notepad application as foreground window.

If you are using other laguages then you will have to call the win32 API's ,FindWindow() and SetForeGroundWindow() through Platform invoke.

P/Invoke Implementation:
since i am not familiar with C# iam showing this code using vb.

'Declare the Win32 API's


Declare Auto Function FindWindow Lib "User32.dll" (ByVal lpClassName As String,ByVal lpWindowName As String) As IntPtr

Declare Auto Funtion SetForeGroundWindow Lib "User32.dll"(ByVal Hwnd As IntPtr) As Long

'Call these API's through your code

Dim Handle as IntPtr = FindWindow(Nothing,"Untitled - Notepad")

SetForeGroundWindow(Handle)

Dimpsi As New ProcessStartInfo("notepad.exe")
psi.WindowStyle = ProcessWindowStyle.Maximized
Dimproc As Process = Process.Start(psi)

Dont have the time to do more but try getting the window handle or use the processID.....

printf("Love");

I can't. Just can not make it work.

The process is already started..

You'll need to P/Invoke SetForegroundWindow(). Visit pinvoke.net for the required declaration.

Woah, lifesavers!
I almost ate myself.

No for real, thanks for help.
Every thing's working fine.
