VC6 里面 调试 不能看 变量值

[ximenchuifeng]

最近学WIN32 编程， 遇到苦难时候， 断点， 调试下，但是在看 监视1 里打入要监视的东西，
等到 运行到断点处后，监视窗口里显示“CXX0017:Error：symbol “xxx”not found”竟然说我的变量没有发现，但是明明已经运行了。。。。

附上代码：

很遗憾的告诉你，VC6就这样，经常这样，我也很郁闷

[雪影]

都提示了变量没有找到，那肯定你没有定义了。

注意变量的有效范围，和变量的大小写

哎呀， 断点 段在这个 地方，比如那个 cxchar。。我在 wm_create 消息里就 看不到啊。。
真的郁闷死了。。

[jiakai1000]

先确保打了sp6补丁，试试把鼠标指针放在变量上面能不能出现当前的值，再不行就用TRACE

鼠标放在上面 有些可以显示出来。。有些不能。

TRACE 是什么，我不知道。。。我太新手了。。

[ximenchuifeng]

额。。TRACE ，查到了。。。呵呵，thanks，再等等，看有没有人来回答我这个问题。。呵呵

[ximenchuifeng]

我了个去，我知道原因了。


比如上面那个 cxChar ， 如果你输入 cx 他出现 cxChar。。

VC6不认识 大写了。。。。谁能告诉我怎么解决。。

[花熊]

Trace1/Trace2之类都可以，在release下不能调试
