Nope, this 'un

:

Since it ainnapparent'ly there, look here:

If all else fails, see if the boogers let you do this in the makefile:

LIBS =  -L"C:/Dev-Cpp/lib"  -mwindows 
CXXFLAGS = $(CXXINCS)   -mwindows
CFLAGS = $(INCS)   -mwindows

Well, it does have it in the compiler options. However, it does not prevent the console from opening. I have a GUI that installs an update.exe when that button is clicked. I used a system(file path); call. Is there a better way that does not create a console window?

Thanks for the help DaWei

If you don't need the console, and you don't want the app to show anything on the screen just use winapi and hide the window.

It's pretty much what Jayme suggests or write a service. Using the API to get the handle of your window and hide it would be the easiest at this point, I suspect.

Don't know why this didn't occur to me before but you could just do:

(Toggle Plain Text)

int main()
{
HWND hwnd = GetConsoleWindow(); // Get console window handle

ShowWindow(hwnd, SW_HIDE);
return 0;
}

hmmm, looks interesting. I'll give that a shot.

Thanks,

Yeah it has been said a lot of times since then, this thread is a few months old and in the meantime I've learned a lot more of Windows programming. Sorry Jayme for misinforming you back then.

When using this method I am getting

(Toggle Plain Text)

[Linker error] undefined reference to `_Z16GetConsoleWindow@0'

I have included the windows header and added the kernel32.lib to the linker items. Is there anything else that must be added? This is the code I am trying to use:

(Toggle Plain Text)

#include <windows.h>
#include <process.h>
 
HWND hwndcs;
HWND hwndnetsp;
HWND hwndsp;
HWND hwndexit;
HDC hdc;
PAINTSTRUCT ps;
RECT rc;
// some other code here...
case WM_COMMAND:
if(LOWORD(wParam) == 1 && HIWORD(wParam) == BN_CLICKED && (HWND) lParam == hwndnetsp)
{
	ShowWindow(hwnd, SW_HIDE);
	system("D:\\dotnetfx.exe");
	hwndcs = GetConsoleWindow(); // Get console window handle
	ShowWindow(hwndcs, SW_HIDE);
	system("D:\\NDP1.1sp1-KB867460-X86.exe");
	hwndcs = GetConsoleWindow(); // Get console window handle
	ShowWindow(hwndcs, SW_HIDE);
	ShowWindow(hwnd, SW_SHOW);
} 
// some other code here...

Or am I missunderstanding... This is not a console application. It is a win32 app. Everything else can show, I just want to get rid of the console that pops up when I use system(); I tried messing with the execl(); but could not make that compile.

Thanks,

According to MSDN you should "define _WIN32_WINNT as 0x0500 or later."

execl is an UNIX thing I believe.

Try using ShellExecute, with the 'nShowCmd' param set to 'SW_HIDE'.
