Opening a file with my application...

I'm writing a video player. When you open it you can browse for the video file to open via an open file dialog. The string I get with that I send it to the function that has the fopen. It works.

Also, if I comment the open file dialog and get the file path via parameters, it works.

However, if I use "Open With..." from Windows, and send the path I get from the parameters (I checked, it's the correct path), the fopen fails. Why is that?

It's between " "! I'll take them out, manually. Any easy way to do it?

Look at the error status of fopen, and let it tell you why.

fp = fopen( blah, "rb" );
if ( fp == NULL ) perror( "humbug" );

Or strerror() if you want a string for a popup.
