OpenFileName Multiselect problem

[Chandrasekharan P]

I have a problem with this code

CString l\_FilePath;
CFileDialog m\_ldFile(TRUE,"txt","\*.txt",OFN\_ALLOWMULTISELECT | OFN\_EXPLORER);
m\_ldFile.m\_ofn.lpstrFilter = "\*.txt";


	
if (m\_ldFile.DoModal() == IDOK)
{
	POSITION temp = m\_ldFile.GetStartPosition();
	while(temp)
	{
		l\_FilePath = m\_ldFile.GetNextPathName(temp);
		m\_lstFiles.AddString(l\_FilePath);		
	}
}

Now the problem. i have 8 files in a folder. when i select all the files and try to put the files in a listbox nothing is displaying. but when i am selecting only 7 files then the files are getting displayed. why is that so?

The buffer to hold the file names may not be big enough. Try this:

char szBuffer[64000] = "";
m_ldFile.m_ofn.lpstrFile = szBuffer;
m_ldFile.m_ofn.nMaxFile = sizeof(szBuffer);

Hi Chandru, Michael Schubert gave you a working solution but it may also fail if the buffer is too small. I like the solution offered by PJ Arends where you dont have to worry about the size of the buffer. Multiple Selection in a File Dialog[^] Its a really good technique. Best Wishes, -David Delaune

Much better solution indeed. My example was really just a suggestion to test whether it's a problem with the buffer being too small.
