MFC编程SetDlgItemText的问题

[jluhongfeng]

我在成员函数中有这样一句，
SetDlgItemText(IDC_EDIT2,s);
IDC_EDIT2是一个Edit Control的ID,s是一个char型的数组，但是编译的时候老是提示我下面的错误，不知道为什么？请各位高人指点啊。错误如下：
error C2660: 'SetDlgItemTextA' : function does not take 2 arguments

看看参数啊，应该为LPCTSTR类型，so……

我记得是这样用吧 GetDlgItem(IDC_EDIT2)->SetDlgItemText(s);

error C2660: 'SetDlgItemTextA' : function does not take 2 arguments 不接受两个参数 函数原型 BOOL WINAPI SetDlgItemText( _In_ HWND hDlg, _In_ int nIDDlgItem, _In_ LPCTSTR lpString );

我看书里的例子也是直接用这两个参数呀，第二个参数也是直接把数组名作为参数传进去

缺少句柄，一般在主线程中就是2个参数，但是在线程中需要加上句柄，在线程中建议用PostMessage。希望对楼主有用。
