C#: How can I hide when you start other programs in C# using Win32API? -

i'm using code:

    /********** code first way **********/     string filepath = "ex";     stratinfo psi = new startinfo(filepath);     psi.windowstyle = processwindowstyle.hidden;     process process = process.start(psi);     process.waitforinputidle();     /********************************************/      /********** code second way **********/     string filepath = "ex";     process process = process.start(new startinfo(filepath));     process.waitforinputidle();      [dllimport("user32.dll")]     private static extern int showwindow (int hwnd, int ncmdshow);      int hwnd = findwindow(null, "main caption");     if (hwnd != 0) {         showwindow(hwnd, 0);     }     /***********************************************/ 

most of programs in way, solved problem.

however, programs have not worked way.

the first way : not possible @ all.

the second way : part, , slow. can hide main window. messagebox still displayed.

how resolve problem? thank answer.

check out winexec function, lets pass visibility parameter:

this may give similar results process, however, it's worth experimenting with.

you mention messageboxes showing - can't control that, because program running in desktop has ability wants desktop, including popping random topmost windows.

try running program service: (this supresses program's ui):

of course, now, when messagebox raised program, windows doesn't display it, program 'locked up' there; , may not have permissions run program service.

why want this, exactly? might suprised @ workarounds community suggests.

good luck anyway.
