Question

简单的MFC代码无法运行，看看什么原因

在设置文件对话框标题时出现错误，代码：void CMyDlg::OnButton1() {CFileDialog Dlg(TRUE,NULL,NULL,NULL,NULL,this);
Dlg.m_pOFN->lpstrTitle="我的自定义文件打开对话框";
Dlg.DoModal();}错误提示：error C2819: type 'tagOFNA' does not have an overloaded member 'operator ->'c:\program files\microsoft visual studio\vc98\include\commdlg.h(56) : see declaration of 'tagOFNA'error C2227: left of '->lpstrTitle' must point to class/struct/union
Error executing cl.exe.m_pOFN是自己定义的吗？在CFileDialog类中没有呢？

Answer 1

type 'tagOFNA' does not have an overloaded member 'operator ->'so you need change Dlg.m_pOFN->lpstrTitle="我的自定义文件打开对话框";
toDlg.m_pOFN.lpstrTitle="我的自定义文件打开对话框";

Answer 2

void CMyDlg::OnButton1() {CFileDialog Dlg(TRUE,NULL,NULL,NULL,NULL,this);
Dlg.m_pOFN->lpstrTitle="我的自定义文件打开对话框";
Dlg.DoModal();}

Answer 3

Dlg.m_pOFN.lpstrTitle="我的自定义文件打开对话框";
