C++ USES the openfilename openfile dialog usage example

This article illustrates the use of C++ using openfilename to open the file dialog box. Specific methods are as follows:

Note that sometimes the dialog box never appears because nMaxFile is not set.

The specific function code is as follows:

char szFileName[MAX_PATH]={0};  

OPENFILENAME openFileName = {0};  

openFileName.lStructSize = sizeof(OPENFILENAME);  

openFileName.nMaxFile = MAX_PATH;  //This must be set, otherwise the open file dialog will not appear. < br / >
openFileName.lpstrFilter = " Text file (*.txt)0*.txt0 All the files (*.*)0*.*00";  

openFileName.lpstrFile = szFileName;  

openFileName.nFilterIndex = 1;  

openFileName.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST;  

  

if (::GetOpenFileName(&openFileName))  

{  

    ::MessageBoxA(hwndDlg, openFileName.lpstrFile, "", MB_OK);  

}

Hope that the article described in the C++ programming to help you.
