Print Screen

Pushing print screen in windows does not save a snapshot to the disk -- it copies the contents of the screen to the clip board (alt+print screen copies only the current window). You need to open an image editing program (mspaint.exe will do) and paste the image in with ctrl+v or edit paste, then save the file.

If you are using DX why not simply catch the PrintScreen event, and then save your buffer to either clipboard or a file?

See Screen Shots here on GD.NET for an exapmle (Haven''t tested that one though)

The AP one works great.

You just need to add

#include <windows.h> #include <stdio.h> HRESULT SaveBitmap( char strFileName[128], PBITMAPINFO pbi, HBITMAP hBMP, HDC hDC ); int g_iSnapshotBitmapNumber,g_iScreenWidth=800, g_iScreenHeight=600;

to the beginning of the file and then you can include it in any project. You can force a 24 bit screenshot by removing the checks for the actual bitdepth and changing the bmiHeader.bitcount to 24.

is a fixed version that allows you to pass the DX surface, the width and the height allowing you to capture any surface at any size at 24bits per pixel with one call:

HRESULT TakeSnapshot( LPDIRECTDRAWSURFACE7 surface, short g_iScreenWidth, short g_iScreenHeight)
