文件过滤问题 [英] File Filtering problem

问题描述

大家好，
我想使用CFileDialog类打开一个xml文件.为此，我使用了以下代码.

static char BASED_CODE szFilter[] = "Scan Report(*.xml)|*.xml||";

CFileDialog dlg(1,"xml","Scan Report",OFN_OVERWRITEPROMPT|OFN_PATHMUSTEXIST|OFN_HIDEREADONLY,szFilter);

但是我收到以下错误..

E:\Jijesh\ReportEx\ReportExDlg.cpp(229) : error C2664: ''CFileDialog::CFileDialog'' : cannot convert parameter 3 from ''char [12]'' to ''const unsigned short *''

请帮助我.

解决方案

我认为您必须将字符串括在_T("")中，例如将"string"封装到_T("string")中. >

对于参数2，您可能会遇到类似的错误，请尝试:

 TCHAR szFilter [] = _T(" );
CFileDialog dlg( 1 ，_ T(" )，_ T(" )，OFN_OVERWRITEPROMPT | OFN_PATHMUSTEXIST | OFN_HIDEREADONLY，szFilter);

Hi all,
I want to use CFileDialog class to open an xml file. For that I''ve used the following codes.

static char BASED_CODE szFilter[] = "Scan Report(*.xml)|*.xml||";

CFileDialog dlg(1,"xml","Scan Report",OFN_OVERWRITEPROMPT|OFN_PATHMUSTEXIST|OFN_HIDEREADONLY,szFilter);

But I am receiving the following error..

E:\Jijesh\ReportEx\ReportExDlg.cpp(229) : error C2664: ''CFileDialog::CFileDialog'' : cannot convert parameter 3 from ''char [12]'' to ''const unsigned short *''

Please help me.

解决方案

I think you have to enclose your strings in _T(""),like "string" to _T("string").

You are probably getting a similar error for parameter 2, try:

TCHAR szFilter[] = _T("Scan Report(*.xml)|*.xml||");
CFileDialog dlg(1,_T("xml"),_T("Scan Report"),OFN_OVERWRITEPROMPT|OFN_PATHMUSTEXIST|OFN_HIDEREADONLY,szFilter);
