Mimimizing the window created by a process

I am creating a process to launch mspaint application using the following code
::CreateProcess(0, strCmdLine.GetBuffer(0), 0, 0, FALSE, 0, 0, 0, &si, &pi)

Once the application is launched, i need to minimise the paint application. How can i do it?

Find the window and minimize it with ShowWindow function

You mean you want to minimize the window of the application that launched the other process, of the window of the application that was launched?

Hi,

It can be done using 6th argument in CreateProcess():
DWORD dwCreationFlags to SW_SHOWMINIMIZED

I need to minimize the application which launched the process

Dosn't ShowWindow(SW_MINIMIZE) work? :confused:
Or "the application which launched the process" has no window at all? :rolleyes:

You can also try to send a WM_SYSCOMMAND with SC_MINIMIZE to the application's main window. But ShowWindow(SW_MINIMIZE) for the application's main window, should do the job.

ShowWindow takes 2 arguments - hwnd and cmdShow.
So minimize the application i need to get the hwnd for that. How can i get it?

Yes, if you are using plain Win APIs

Since you created a window in your application (and you didn't say you hadn't done it) that you got somewhere in your code this window handle returned by one of the Win API such as CreateWindow(Ex) or CreateDialog or something similar

If I have the handle and try doing all this

::SetWindowPos(hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE );
SendMessage(hwnd, SW_SHOW,0,0);
ShowWindow(hwnd, SW_SHOW);
SetForegroundWindow(hwnd);
BringWindowToTop(hwnd);

Still I am not able to bring the window to top

I asked about minimizing the parent window because i need the focus on the newly created application, but it is not happening

What is the hwnd you are using here?

What is "not happening"? Minimizing of your application window? Or what? :confused:

The parent window is creating a process and I am not able to bring the newly created window to top. For this reason i have tried to minimise the parent window so that the focus will be on the newly created application.
In short I need to have the newly created application in the top. How can i do that
