 Hallo,

wer schonmal einen D3D Hack geschrieben hat, kennt das Problem sicherlich. Wenn man vom Window in den Fullscreen Modus wechselt, gibt es einen DirectX Error und das Spiel stürzt ab. Damit man schnell testen kann, welche Ressourcen man freigeben muss und welche nicht, habe ich ein einfaches D3D9 Programm geschrieben, mit dem man das machen kann. Baut einfach das ein, was ihr braucht und schaut ob es beim Switch abstürzt. Der Code enthält bereits eine Font, ein Sprite und eine Line.

TEXT Code:
  1. #include <d3dx9.h>
  2. #include <stdio.h>
  3. #pragma comment(lib, "d3d9.lib")
  4. #pragma comment(lib, "d3dx9.lib")

  6. LPDIRECT3D9 pD3D = NULL;
  7. LPDIRECT3DDEVICE9 pDevice = NULL;
  8. D3DPRESENT_PARAMETERS pp;
  9. LPD3DXFONT font;
  10. LPD3DXSPRITE sprite;
  11. LPD3DXLINE line;

  13. bool windowed = true;
  14. int reset = 0;

Mit F1 kann man den Vollbildmodus (de)aktivieren.
