please help with file extension filter stuff.

Hi everyone.

I'm using the "file" extension in an app I'm making. I open up its save dialogue so someone can choose where and with what name to save data (an INI file) BUT I want the file they create to be forced to have a custom extension (".ABCD" for instance)

I tried using the filter option in the file object and it now says at the bottom. Save as type: .ABCD BUT when I save a file, it seems to have no extension at all.

How do I use the filter feature in the file extension to only show files ending with my custom .ABCD and only allow files to be saved with the extension .ABCD?


Thanks

The path to open the file browser on must have the extension in it:
"C:\bleh\*.ABCD"
It works for me, however you cannot force the user to save this. (They can just type in *.EFGH and press enter) What you CAN do is break apart the file path, and replace the extension with your own, even if they saved it with a different extension.

Thanks much for the info LB This should give me exactly what I needed.

Don't you have to put in "ABCD File|.ABCD" as the filter? It's a description and extension pair, if you only give it one, it'll use it as the filetype description (with no extension).

Well yes, but the filter only affects the visible files when it changes. When the dialog first opens up, it uses the default filename you give it to filter the visible files. Kind of annoying, but that's how it is.

My point was that if you set the filter up correctly it will add your extension to the file if the user doesn't

EDIT:
I did this:
File: Set extension filter to "ABCD File|*.ABCD"
File: Set default extension to ".ABCD"
File: Open save selector at ""
String: Set string to result of file selector

And got back bvc.ABCD even though I didn't type .ABCD into the file selector.

EDIT2: And it filtered to .ABCD files without me having to specify *.ABCD as the default filename

But this doesn't work if you specify a directory to open on. I did what you did and I can confirm it, but opening on a specific directory doesn't seem to allow this.

thanks alot guys, this is really useful information!

To be extra safe I perform a check and add the extension while saving if its not there.
