Работа с ресурсами без TResourceSteram.

FindResource + LoadResource + LockResource.

Определяем размеры картинки хранящейся в ресурсах:

Code: Function PictureSize: TSize; Var. ResHandle: HWND; ResData: HWND; BMI: PBitmapInfo; Begin. Result.cx := 0; Result.cy := 0; ResHandle := FindResource(HInstance, MAKEINTRESOURCE(200), RT_BITMAP); If ResHandle <> 0 then. Begin. ResData := LoadResource(HInstance, ResHandle); If ResData <> 0 then. Try. BMI := LockResource(ResData); If Assigned(BMI) then. Try. Result.cx := BMI.bmiHeader.biWidth; Result.cy := BMI.bmiHeader.biHeight; Finally. UnlockResource(ResData); End; Finally. FreeResource(ResData); End; End; End;

Получаем список всех ресурсов

Code: Function GetResourceList: Boolean; Var. Errors: Cardinal; Function CallBack(hModule: HMODULE; lpType: PChar; LpzName: LPTSTR; lParam: Longint): BOOL; stdcall; Var. Size: Cardinal; Begin. Result := True; If Assigned(lpzName) then. Begin.

Отрисовываем картинку из ресурса на форме:

Code: Procedure ShowPicture; Function Rect(Left, Top, Right, Bottom: Integer): TRect; Begin. Result.Left := Left; Result.Top := Top; Result.Right := Right; Result.Bottom := Bottom; End; Var. Bitmap: HBITMAP; BitmapSize: TSize; DC, BitmapDC, OldDC: HDC; BLeft, bTop: Cardinal; _Rect: TRect; S: String; Pen: HPEN; Begin. Bitmap := LoadBitmap(HInstance, MAKEINTRESOURCE(200)); If Bitmap <> 0 then. Try. BitmapSize := PictureSize; DC := GetDC(Handle); Try. BitmapDC := CreateCompatibleDC(DC); Try. OldDC := SelectObject(BitmapDC, Bitmap); Try. BLeft := (Width - BitmapSize.cx); BTop := 0; StretchBlt(DC, 0, 0, bLeft, BitmapSize.cy, BitmapDC, 0, 0, 1, BitmapSize.cy, SRCCOPY); BitBlt(DC, bLeft, bTop, BitmapSize.cx, BitmapSize.cy, BitmapDC, 0, 0, SRCCOPY); SetBkMode(DC, OPAQUE); If hFontBold <> 0 then.
