Question about CFileDialog class
-
Did you try debugging? Where exactly is the app crashing?

The debugger does not take me to any line in my code. It crashes after the second filedialog has been displayed and all i get is a "Show disasembly" option which does nothing:(
How can that happen! I hope you have set break points. Have you?

where do you want me to set brakepoints? i've set them for every line in my code but the application dies while browsing for the file (ie: CFileDialog::DoModal() never returns)
What does the call stack look like? Is there any line that points to code for which you have source code? I assume you have built your application for debug...:~ -- Rog

When you come to Domodal set a breakpoint after it

...it dies during CFileDialog::DoModal() method (i mean, it dies while my dialog waits for CFileDialog::DoModal() to return)

That's the disassembly code, but i don't know what to do with it, i don't think it helps
Did you try displaying a message box before and after your CFileDialog creation? What happens in that case?

I have a dialog with two browse buttons on it. If i press the frist one, select a file than press the seccond one, my application crashes and i can't figure out why :( . Here's the code:
//first browse button
void CAddEquipDlg::OnBnClickedBrowsedb()
{
char szFilters[]=
"Access DB (*.mdb)|*.mdb|All Files (*.*)|*.*||";CFileDialog fDlg(TRUE, "mdb", "\*.mdb", OFN\_FILEMUSTEXIST| OFN\_HIDEREADONLY, szFilters, NULL ); if (fDlg.DoModal()==IDOK) { m\_sDB = fDlg.GetPathName(); } SetCurrentDirectory(m\_sCurDir); SetDlgItemText(IDC\_DB,m\_sDB); AfxGetApp()->WriteProfileString("Connection", "Database",m\_sDB);}
//seccond browse button
void CAddEquipDlg::OnBnClickedBrowseequip()
{char szFilters\[\]= "CSV Files (\*.csv)|\*.csv|All Files (\*.\*)|\*.\*||"; CFileDialog fDlg(TRUE, "csv", "\*.csv", OFN\_FILEMUSTEXIST| OFN\_HIDEREADONLY, szFilters, NULL ); if (fDlg.DoModal()==IDOK) { CString bla = fDlg.GetFileTitle(); m\_sEQUIP = fDlg.GetPathName(); } SetCurrentDirectory(m\_sCurDir); SetDlgItemText(IDC\_EQUIP,m\_sEQUIP);}
It crashes two out of tree times (with a send/don't send error message in release) and this is the debug info
First-chance exception at 0x7ca5159e in AddEquip.exe: 0xC0000005: Access violation reading location 0x62883720.

What happens if you reverse this process? Which of the four statements after
DoModal()is crashing? Set a breakpoint to find out.

None of the four statements after DoModal() is crashing!..none! DoModal() doesn't even return. Anyways, i've narrowed it down. It crashes when i move trough folders in the CFileDialog window. And it doesn't really matter wich of the two buttons i press first.

This is just a complete guess, but how about commenting out everything after the
DoModal()call?

this was my last resort too but it still failed :(. I'm putting this thing to rest and i'll get to it some other time... Maybe there's a problem with my computer( a virus or smth...don't know ). The problem is clearly in the CFileDialog class but i can't figure it out.

To further verify that, use
GetOpenFileName()instead.
