Hi kagami01,

I'm not sure if this works, but you can give it a try: With 'GetConsoleWindow' you should be able to retrieve the HWND of the DOS-window, then you can ShowWindow( ..., SW_HIDE ); to hide it.

Hope that helps,

ZOPPO

you mean like the code below here:
int WINAPI WinMain( HINSTANCE,  HINSTANCE, LPSTR, int)
 
 

{

  

  HWND Console;             

  AllocConsole ();

  Console=FindWindowA ("ConsoleWindowClass",NULL);

  ShowWindow (Console,SW_HIDE);
 
 

 my other c++ code here
 
 

 return 0;

}

Open in new window

Sorry, seems I didn't read you code-snippet carefully - you use 'FindWindowA', but I suggested to use 'GetConsoleWindow'.

So, it should be:

HWND console = GetConsoleWindow();
if ( NULL != console )
{
 ::ShowWindow( console, SW_HIDE );
}

Hm - to get 'GetConsoleWindow' compiled you need to define _WIN32_WINNT as 0x0500 or to retrieve the function pointer 'manually' using LoadLibrary and GetProcAddress.

I'm not sure since I never used dev c++ - anyway, LoadLibrary and GetProcAddress are Win32-API functions, so you should be able to use them ...

Yes, you get this since either you have a old SDK or _WIN32_WINNT is less than 0x0500.

How do you invoke your application?

Should it run in background with no user interface? Or does it has a window to show? Or do you start it in a console (DOS Box) and you don't want a further console to pop-up?

Dear Zoppo you were right i forgot the put
 #define _WIN32_WINNT 0x500 before the #include <windows.h>
 and i added in dev c++ in "tools"--->"option compilation"--> "-lgdi32"
so the i compiled the exe without problem and it worked for win vista thank you so much Zoppo.

question?!?!?!

i got a file after the compiling like follow:

Myapplication.exe.Manifest

i need it in in where the .exe folder is  or not??

Yes. The .manifest is some kind of configuration file where parts of the information was stored that formerly was in Windows registry.
