从系统中取得指定资源图像

在Winuser.h中定义了一些系统常用的资源，比如对话框的图标，某些按钮上的图像等。
以下是部分OEM资源序号和一些标准ICON的ID：
//---------------------------------------------------------------------------

// Standard Icon IDs
#define IDI_APPLICATION MAKEINTRESOURCE(32512)

我们能够通过LoadBitmap从系统中取得指定资源图像:

void __fastcall TMainForm::Button1Click(TObject *Sender)
{
for(int i=0; i<30; i )
{
HBITMAP hBitmap = ::LoadBitmap(NULL, MAKEINTRESOURCE(32734 i));
TImage *img = new TImage(this);
img->Picture->Bitmap->Handle = hBitmap;
Canvas->Draw(9 i *16, 9, img->Picture->Bitmap);
delete img;
DeleteObject(hBitmap);
}
for(int i=0; i<5; i )
{
HICON hIcon = ::LoadIcon(NULL, MAKEINTRESOURCE(32512 i));
TImage *img = new TImage(this);
img->Picture->Icon->Handle = hIcon;
Canvas->Draw(10 i *32, 50, img->Picture->Icon);
delete img;
DeleteObject(hIcon);
}
}
