用了一下dbwin很方便。 下载的地方： http://dilascia.com/TraceWin.htm我用vc6, 所以下载 3.0 用的时候非常方便，在使用的文件前#include "TraceWin.h" 这样，后afxDump和Trace的字符串，都输入到TraceWin.exe这个程序中了。 调试ole, c/s的程序非常方便。  后面附上源码:   /**///////////////////////////////////////////////////////////////// // TraceWin Copyright 1995-1999 Paul DiLascia
// If this program works, it was written by Paul DiLascia.
// If not, I don't know who wrote it.
//
// NOTE: If you're using PixieLib, you don't need to include this file.
// It's already included by the library.
//
// ***************************************************************************
// TraceWin is a tool that displays MFC diagnostic (afxDump, TRACE) output
// in the window of the TraceWin applet.
//
// To use TraceWin, you must #include this file somewhere in your main program
// file (typically where you implement your CWinApp). Since this file contains
// code, you should #include it in only once--i.e. NOT in StdAfx.h--or you'll
// get multiply-defined symbol errors in the linker. This file contains an
// auto-initializing static variable that works in most cases; but you may miss
// some TRACE output from constructors of static objects. If so, you can
// manually call PxlTraceInit before your first TRACE call.
//
// To see the output, you also need the TraceWin applet, TraceWin.exe, which
// you can download http://pobox.com/~dilascia
//
