how can i solve the problem does any body has an idea because i dont know what to do how i find the error and solve it please help me

The information you provided is not enough to come to any conclusions. You should start the program in the debugger (hit F5) and when it crashes you will know the exact context of the crash. If you don't come to any conclusions yourself, post your findings here and somebody might get an idea.

this is the function where he stops :
void CNerofiddlesDlg::OnBrowse()
{
// TODO: Add your control notification handler code here
static char BASED_CODE szFilter[] = "MP3 Files (*.mp3)|*.mp3|All Files(*.*)|*.*||";
CFileDialog dlgOpen(TRUE, NULL, NULL, OFN_FILEMUSTEXIST, szFilter, this);
if (dlgOpen.DoModal() == IDOK)
{
mstrPathName = dlgOpen.GetPathName();
mstrFileName = dlgOpen.GetFileName();
medtFileName.SetWindowText(mstrPathName);
(here is the error) if (pndiDeviceInfos->nsdisNumDevInfos > 0)
{
mbtnBurn.EnableWindow(true);
}
}



}
and this is the debug report is the first time ive been working with the debugger so i dint have any idea what this means or what i can do a´bout it :
