I'm a newbie too and have had the same problem applying the MFC example to my own app. The problem was that wasn't giving a complete path. Use szPathName instead of szFilename from the MFC file dialog.
Another way is to have the directory containning your data in your PATH environment variable. This, however is not very elegant. - Nick - ________________________________ > From: [EMAIL PROTECTED] > To: [email protected] > Date: Tue, 28 Aug 2007 13:18:52 -0400 > Subject: [osg-users] osgviewerMFC example crash in 2.1.8 > > I’m still finding my way around OSG so I wanted to find out if this issue is > mine before I continue pulling my hair out. > I downloaded and built OSG 2.1.8.
