你在什么系统下有问题,我在2000下用也没有问题!!

[program2100]

找到DLL文件，用VS的工具%VS Dir%\Common\Tools\DEPENDS.EXE浏览，看看你调用的函数存在吗?

[踏平扶桑]

可能你的系统里的那个dll里没有那个函数造成的

[qjqmoney]

你是不是在WinXP下打包，在Win98下运行？这样有可能是动态库不兼容，你可试试在Win98下打包。

[moleboy]

在9X
下不正常!
连源程序都无法运行!
已经找到!是DLL不兼容！
请问XP的RASapi32。dll 的RasGetConnectionStatistics函数可以用
98的RASapi32。dll的那个函数代替！

错了，是vb api的问题
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
好像差个空格。

[aiur2000]

去掉alias " SendMessageA",或者去掉sendmessageA前面的空格
我碰到过这个问题。

[flc]

学习

[busisoft]

我这里也没有问题

[pcwak]

工程-->引用
试试看

[moleboy]

不允许引用!

去掉alias " SendMessageA",或者去掉sendmessageA前面的空格

我的SendMessageA前没有空格啊
