你附的程式碼好像怪怪的，能跑嗎?

比如說怎會GetDC，換後create canvas但都沒用？ bitmap那個物件new出來的和後面用的不一樣…
能否先測一下你貼的程式是否能跑，然後再放上來，我可以幫忙測一下是怎樣的情形。當然，我不知道是否在你copy前使用BringWindowToTop 或是SetForegroundWindow會有用?!

//不好意思,code 有點問題,我重貼

//還有我會試試你的方法,謝謝

int i = 0;
AnsiString bmpName;

while(i < 7)
{
HDC dc;
dc = GetDC(Handle);
TCanvas *nCanvas = new TCanvas;
nCanvas->Handle = dc;
Graphics::TBitmap *bmp = new Graphics::TBitmap;

bmp->Width = MainForm->pageControl1->Width;
bmp->Height = MainForm->pageControl1->Height;
SetStretchBltMode(MainForm->Canvas->Handle, STRETCH_HALFTONE);
bmp->Canvas->CopyMode = cmSrcCopy;
bmp->Canvas->CopyRect(Rect(0, 0, bmp->Width, bmp->Height),
MainForm->Canvas,
Rect(0, 0, MainForm->ClientWidth, MainForm->ClientHeight));

bmpName = "C:\\" IntToStr(i) ".bmp";
bmp->SaveToFile(bmpName);

i =1;
if(i < 7)
MainForm->pageControl1->ActivePageIndex = i;

delete bmp;
delete nCanvas;
ReleaseDC(NULL, dc);
}
