请帮忙看下这段代码,编译器不识CWnd
void CMySMSDlg:: QQSendMessage()
{
CString str;
CWnd* pMainWnd = AfxGetMainWnd()->GetWindow(GW_HWNDFIRST);
while (pMainWnd)
{
HWND hWnd,hNext;
hWnd = pMainWnd->m_hWnd;
pMainWnd->GetWindowText(str);
if(str.Find ("聊天")>-1){//找到聊天主窗口Begin
//找RichEdit
hWnd=FindWindowEx(pMainWnd->m_hWnd,NULL,"#32770",NULL);
pMainWnd = CWnd::FromHandle(hWnd);
hWnd=FindWindowEx(pMainWnd->m_hWnd,NULL,"AfxWnd42",NULL);
CWnd* pChildWnd=CWnd::FromHandle(hWnd);
int nLen = str.GetLength ();
hNext = FindWindowEx(pChildWnd->m_hWnd,NULL,"RICHEDIT",NULL);
if(hNext){//找到消息填写控件
CRichEditCtrl* pRich=(CRichEditCtrl*)(CWnd::FromHandle(hNext));
pRich->GetWindowText (str);
pRich->SetSel (nLen,nLen);
pRich->ReplaceSel ("成都外国语学校");//填上将要发送的内容
}else return;
//找消息发送按钮
hWnd=FindWindowEx(pMainWnd->m_hWnd,NULL,NULL,NULL);
while (hWnd) {
pChildWnd=CWnd::FromHandle(hWnd);
pChildWnd->GetWindowText(str);
if(str.Find ("发送")>-1){
pChildWnd->SendMessage (BM_CLICK);//发送
return;// 退出
}
hWnd=FindWindowEx(pMainWnd->m_hWnd,hWnd,NULL,NULL);
}
return;
}//找到聊天主窗口End
else pMainWnd = pMainWnd->GetWindow(GW_HWNDNEXT); //继续找
}//While
}

[解决办法]
源文件里有不应该出现的字符
[解决办法]
有时C++编译器提示的错误实在是让人摸不着头脑。LZ应该从第一个错误找原因，往往第一个错误解决了，其它的错误都会消失。
[解决办法]
vc.net里没那个CWnd类，回到6.0试试。花点时间了解一下新版本。
[解决办法]
#include <afxwin.h> // MFC 核心组件和标准组件
#include <afxext.h> // MFC 扩展
#include <afxcmn.h>// MFC 对 Windows 公共控件的支持
