屏幕截取是令人比較感興趣的事情.雖然現在有不少應用程序如HYPERSNAP等可以用來截取你所喜歡的屏幕畫面,但是如果能把這個功能加到自己的程序中,就更能利用它強大的作用.

下面用VC來逐步介紹在Windows95下的實現過程.首先我們要確定屏幕截取的區域,用LPRECT結構來定義.可以截取一個窗口,或整個屏幕.以下代碼把選定的屏幕區域拷貝到位圖中.
</BIG></P><PRE>HBITMAP CopyScreenToBitmap(LPRECT lpRect)
//lpRect 代表選定區域
{
HDC hScrDC, hMemDC;
// 屏幕和內存設備描述表
HBITMAP hBitmap, hOldBitmap;
// 位圖句柄
int nX, nY, nX2, nY2;
// 選定區域坐標
int nWidth, nHeight;
// 位圖寬度和高度
int xScrn, yScrn;
// 屏幕分辨率
// 確保選定區域不為空矩形
if (IsRectEmpty(lpRect))
return NULL;
//為屏幕創建設備描述表
hScrDC = CreateDC("DISPLAY", NULL, NULL, NULL);
