CFileDialog doesn't update when I change the file type.
-
I am using CFileDialog for a "save as" where I have to choices for file types: All Files or Avi Files. I just noticed something very strange and wondered if anyone else has seen the same thing, or better knows how to fix it. First of all, the "save as" function is done correctly, so 99% of the problem is solved. It comes up with All Files and indeed shows all files. The problem comes when I change to show only avi files. The window goes blank. If I go back to all files, it stays blank. Only if I choose a different folder is it refreshed properly (with either all or avi files). I tried it in Paint and there if you change the file type, the window refreshes correctly. In CFileDialog it doesn't. My code is: CFileDialog filedlg( FALSE, "avi", // default extension "mip1.avi", // current file name OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_LONGNAMES, "All Files (*.*)|*.*|Avi Files (*.avi)|*.avi||", NULL); Has anyone else seen this, or can tell me what is wrong? Thanks, Ilan
Try using the following code - it should work just fine. Good luck!
CFileDialog filedlg( FALSE, "avi", // default extension "mip1.avi", // current file name OFN_FILEMUSTEXIST | OFN_PATHMUSTEXIST | OFN_LONGNAMES, "All Files (*.*)\0*.*\0Avi Files (*.avi)\0*.avi\0", NULL); -

Strange. Is this the same in Release and in Debug ? Do you have the same problem if you have more than two filters (try adding an Mpeg Files (*.mpeg)|*.mpeg ? What if you exchange All Files and Avi Files in the string (so that the default extension is also the one that comes as forst in the string ) ? ~RaGE();

That was a great idea to try the Release as well as the Debug. I didn't think of that. Unfortunately, it also has the problem in Release. I also added mpeg and it indeed gave me 3 choices as expected. Still the refresh problem is there. I looked in a couple of other programs I have and the problem exists there as well. I just never noticed it until today. Maybe it is connected to .NET which I added fairly recently? Hard to believe, but who knows. It is strange that I never would have seen this before. BTW, I have an avi file in the directory, so even if I put avi files first I will still see them properly. It is only when I pull down the combo box and change the file type that the refresh fails. I'm really stuck as to why.

Just out of curiousity: does the behaviour remain if you set the OFN_EXPLORER flag as well? I'm thinking about some events that does not occur if the OFN_EXPLORER flag is omitted, e.g. OnTypeChange. -- Roger
It's supposed to be hard, otherwise anybody could do it!

Your code snippet works fine for me. What happens if you use
GetOpenFileName()instead?

Hi IlanTal, your code worked. Whats problem?

That was an idea worth investigating. It turns out that OFN_EXPLORER has no connection to the problem. I added the flag and it works correctly when "Use managed extensions" is No and incorrectly when it is Yes. Now I have complete control of when it appears. Unfortunately, in the real world I need managed extensions since I use the .NET, but at least I know where the problem is. That is more than I knew when I started to ask questions on the board. The bottom line: the code project is very useful....

How so? I have v1.1 of the .NET Framework installed.

Is this a Managed C++ question? If so, have you tried here?
