Open File Dailog with Multiple Files Selection - C / C++ / MFC Discussion Boards

In the example above, it did know.... It was ..."file.ext"...

If you are talking about files loading in your software, and you are using MFC, then CDocTemplate has a member function MatchDocType you may want to look at.

If you cannot tell the type by looking at the extension, or by looking inside the file, simply accept your PC does not have psychic powers.

If you are adding file names to the control, how could you not know it's extension?

how to find hidden windows restricted due to mandatory profile

Hi,

I have administrative access on the domain but mandatory profile on my login user is causing me not to see the display settings. When I right click in black area of the desktop to bring display properties windows, I can see just effects tab, all other tabs (for screensaver, coler scheme) are not seen. So I wanted to bring these windows by some other way and want to change the color scheme and save it. How may I do it programatically? My operating system is windows 2000.

thanks

Is it possible to know form which ip a connection request has been sent to our application which has been listening at a certain port, before accepting it?

Thank you.

Hi all,

I want to write an app which should install SNMP services in the target system. Sysocmgr.exe can do this but I need the required redistributables. Can you plz tell whether SNMP services redistributables are available or not? Is there any other option by which I can install SNMP services in the target machine through MFC?

Thanks in advance.

Hi to all,
I want to implement an Open File Dailog to select multiple files.
I have written code (following), but when I select more files ( i tried for more than 12 files) then control goes to return;.
I think it cause due to numbers of characters in all file path; As when same code i tried for other files with long file name & located at long location(long file path), control goes to return; when I select more than 4 files.

What might be the problem? Help me.

CFileDialog m_Open_Dialog(1,0,0,OFN_ALLOWMULTISELECT | OFN_EXPLORER ,"Text Files (*.txt)|*.txt||",0);<br />
<br />
	if(m_Open_Dialog.DoModal() != IDOK)<br />
		return;<br />
<br />
	CString m_strPath;<br />
	char *sFile_Name = m_Open_Dialog.m_ofn.lpstrFile;<br />
	int iCount =0;<br />
<br />
// FOR SINGLE FILE SELECTION<br />
	if( strlen(m_Open_Dialog.m_ofn.lpstrFileTitle) != 0)<br />
	{<br />
		m_strPath.Format("%s",sFile_Name);<br />
		iCount++;<br />
		return;<br />
	}<br />
<br />
	sFile_Name += ( strlen(sFile_Name) + 1);<br />
<br />
// FOR MULIPLE FILE SELECTION<br />
	do<br />
	{<br />
		m_strPath.Format("%s",sFile_Name);<br />
		iCount++;<br />
<br />
		sFile_Name += ( strlen(sFile_Name) + 1);<br />
	}while(strlen(sFile_Name)!=0);<code><br />
<br />
Thanks & Best regards,<br />

CFileDialog m_Open_Dialog(1,0,0,OFN_ALLOWMULTISELECT | OFN_EXPLORER ,"Text Files (*.txt)|*.txt||",0);
DWORD MAXFILE = 2562; //2562 is the max
m_Open_Dialog.m_ofn.nMaxFile = MAXFILE;
char* pc = new char[MAXFILE];
m_Open_Dialog.m_ofn.lpstrFile = pc;
m_Open_Dialog.m_ofn.lpstrFile[0] = NULL;

if(m_Open_Dialog.DoModal() != IDOK)
return;

this will solve problem
by default buffer size for selected file path is small (for more files)
just make it big

It's working. Thanks for reply.

Also when I increase the value of MAXFILE, then i could select more files.

Is it the first non-static control on the dialog?

So you click the OK button with the mouse and it does nothing?

I want my socket to listen to any ip address having the a perticular series.
For example it should accept the client requests having address series as

When is called AfxOleInit() anywhere in application (is standard in VS 7) then by the closing application this fallen. When I used WIA driver (e.g. aquire image from scanner), then all is OK, but by the closing main application this fallen:

CCmdTarget::~CCmdTarget()
{
#ifndef _AFX_NO_OLE_SUPPORT
if (m_xDispatch.m_vtbl != 0)
((COleDispatchImpl*)&m_xDispatch)->Disconnect();
ASSERT(m_dwRef <= 1); <<<<<<<< error is here (m_dwRef == 2)
#endif
#ifdef _AFXDLL
m_pModuleState = NULL;
#endif
}

I don't know why is m_dwRef == 2 and therefore my application fallen...
