VC++6.0中Debug和Release两个版本有什么不同啊?为什么前者一般要比后者大一些?

Debug比Release里面多了很多调试信息，所以前者比后者大，比如说assert在Release版本就不起作用，还有，如果是用MFC，那么调试版本用的是安装VC6时带的动态库，所以没有安装VC6的机器没有办法运行MFC的Debug版本程序，而Release可以运行。

关于timeSetEvent的回调函数

Private Sub Form_Click() lTimeID = timeSetEvent(100, 0, AddressOf TimeProc, 0, 1) End Sub Private Sub Text1_Change() If Val(Text1.Text) >= 100 Then TimeEnd End Sub ========================== Public Declare Function timeSetEvent Lib "winmm.dll" (ByVal uDelay As Long, ByVal _ uResolution As Long, ByVal lpFunction As Long, ByVal dwUser As Long, _ ByVal uFlags As Long) As Long Public Declare Function timeKillEvent Lib "winmm.dll" (ByVal uID As Long) As Long Public lTimeID As Long Public Sub TimeProc(ByVal uID As Long, ByVal uMsg As Long, ByVal dwUser As Long, _ ByVal dw1 As Long, ByVal dw2 As Long) Form1.Text1.Text = Val(Form1.Text1.Text) + 1 End Sub Public Sub TimeEnd() timeKillEvent lTimeID End Sub 变通下不就可以了么

显示JPG有那么麻烦吗？ //sPath为jpg图片地址 CImage img; img.Load( sPath ); if ( !img.IsNull() ) { HBITMAP hBitMap = img.Detach(); m_FpPhoto.SetBitmap( hBitMap ); //m_FpPhoto为图像控件，类型为BITMP } ~
