Here's a code for you using CFileDialog

CFileDialog *pDlg=new CFileDialog(true);
if(pDlg->DoModal ()==IDOK)
{
CString str=pDlg->GetFileExt ();
if(!str.CompareNoCase ("txt")) // Compare returns 0 if successful
	AfxMessageBox ("Text File Selected");
else
	AfxMessageBox ("Select text files only");

	}

Hope this helps you...

you can use CString::Find()
If you find the extension that you specified in the Find method you would get the index from where the extension starts. You can use this and validify the file extension....
You can also extract the file extension from the string and then use it for validation.(See as I did in my previous post)
There could be some other possible ways also...

Validate it for what?

Wrong in what context?

Hi all.

I'm creating a NT service which listens for connection requests on localhost and some arbitrary port. The service needs to be as sturdy as possible. I have a main thread wich listens for connections, and I create a new thread for every connection request. I need to make sure that the main thread keeps on listening for connections and not bomb out. Has anyone ever had major problems binding to the loopback address and listening for incoming connections. In other words, what is the likelyhood of getting major errors while trying to bind and listen for incoming connections ?

Cheers

Hi, I need to find the French, German, Spanish and Italian translation of the text which is displayed on the windows message box buttons: OK, Cancel, Yes, No, Abort, Retry and Ignore. Can anyone provide them, or point me to somewhere where I'd find them myself?

in french :

Cancel : Annuler
Yes : Oui
No : Non
Abort : Arrêter
Retry : Réessayer
Ignore : Ignorer

BTW, if you use MessageBox, windows should already get the system's correct translations.

Hi,

When I am using _bstr_t variable (member variable) then I am getting Null Reference exception while destorying the class object.In that class,I am assigning different values to _bstr_t member variable.

When we are assigning different values to that variable do we need to allocate any memory for that variable explicitly before assigning the values to it. or else how can we solve this problem. Please give to me any suggestions

Thanks & regards,

I don't think there's any function to get that, but it's RGB( 128, 0, 0) (at least for VC6).
