there is few ways to do it..
. If you don't use OWL inviroment you (or if you don't want to..)
still can use Windows API. there is enough functions to create,
use and destroy after, functions for it.
Try to finde information in HELP file on those functions names:
CreateCompatibleBitmap,CreateCompatibleDC,GetDC,SelectObject,
BitBlt, StretchBlt,LoadBitmap,(from resource ),
and the most powerfull is CreateDIBSection. It's when you got a
complete control on your bitmap.
And never forger that you still got one incredible tool: Resourse WorkShop.
But for any cases :
OWL example of Setup and Destroy functions.
variables : (defined before..)
HDC BWDC;
HBITMAP BWinBMP;
HGDIOBJ LastBitmap;
//&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
void TMyWindow::SetupWindow()
{
TFrameWindow::SetupWindow() //(type of the class depends on you
application)
const int BMPsizeX = 100;
const int BMPsizeY = 100;
HDC WDC=GetDC(HWindow);
BWDC=CreateCompatibleDC(WDC);
BWinBMP=CreateCompatibleBitmap(WDC,BMPsizeX,BMPsizeY);
LastBitmap=SelectObject(BWDC,BWinBMP);
ReleaseDC(WDC,HWindow);
};
//############################################################################
#
void TMyWindow::EvDestroy()
{
SelectObject(BWDC,LastBitmap);
DeleteObject(BWinBMP);
DeleteDC(BWDC);
TFrameWindow::EvDestroy();
};
//############################################################################

Bye,
