open application in hidden mode

[_Superman_]

Is it a cosole application? Try using CreateProcess instead with STARTF_USESHOWWINDOW in the dwFlags member of STARTUPINFO and SW_HIDE in its wShowWindow member.

What type of exe you are using...?

[JM2251]

command line exe

[JM2251]

yes, this is console application

[_Superman_]

In that case, the solution that I gave using CreateProcess will work.

I tried this again and it works perfectly.

wchar_t szCommand[] = L"C:\\Windows\\System32\\Cmd.exe";

STARTUPINFO si;
::ZeroMemory(&si, sizeof(STARTUPINFO));
si.cb = sizeof(STARTUPINFO);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;

PROCESS_INFORMATION pi;

::CreateProcess(0, szCommand, 0, 0, 0, 0, 0, 0, &si, &pi);

yes this will hide the command prompt but what about the other application which will launch through command prompt.

wchar_t szCommand[] = L"-m -l";//command line parameter for application

STARTUPINFO si;
::ZeroMemory(&si, sizeof(STARTUPINFO));
si.cb = sizeof(STARTUPINFO);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_HIDE;

PROCESS_INFORMATION pi;

::CreateProcess(_T("myapp.exe"), szCommand, 0, 0, 0, 0, 0, 0, &si, &pi);

First try with SW_SHOWNORMAL mode. if it is working fine then try with SW_HIDE. If it is also not working then check the exe path and command line arguments. Is it running in normal mode when you using SW_HIDE argument...?

You're correct: Cmd is hidden but the app it's executing not. Some solutions: - create a shortcut to the exe and run that one. In the shortcut you can set options to hide it. - If it is a console app you could route the display output to a NULL device (example: Dir > null). See createprocess options. Hope this helps
