Open dialog box issue

Hi,

i am using the GetOpenFileName and "OFN_FILEMUSTEXIST | OFN_NONETWORKBUTTON | OFN_PATHMUSTEXIST" flags to enable the User to select a file of any type, but when i try to open a file with URL extension the dialog box hangs up( not responding ) !!

Can you tell me please, how can i fix this issue?

Thanks in advance.

Could you post a code snippet? It would be helpful to see how your OPEFILENAME struct is set up.

Code:

---

                char szFile[512] = { "\0" };
                OPENFILENAME ofn;

                ZeroMemory( &ofn, sizeof( OPENFILENAME ) );

                ofn.lStructSize                = sizeof( OPENFILENAME );
                ofn.Flags                = OFN_FILEMUSTEXIST | OFN_NONETWORKBUTTON | OFN_PATHMUSTEXIST ;//| OFN_NODEREFERENCELINKS
                ofn.lpstrFilter                = "*.*";
                ofn.lpstrTitle                = _("Select a File");
                ofn.lpstrFile                = (LPSTR)szFile;
                ofn.nMaxFile                = sizeof( szFile );
                ofn.lCustData                = (DWORD)NULL;
                ofn.lpstrFileTitle        = NULL;
                ofn.nMaxFileTitle        = NULL;

                if ( GetOpenFileName( &ofn ) )
                {
                        szSelectedFile->Append( ofn.lpstrFile );
                }

Been a while but IIRC...

The strings must be NULL terminated and the filter has a special format (check MSDN) and has to be double null terminated.

If the create fails call GetLastError() and check what went wrong.

Now it works correctly:o
Thanks for help.


But i have another problem :
I have created a shortcut by right-clicking the Dial-up connection under "Network Connections" and then selected "Create Shortcut" from the context menu. After that i have renamed the shortcut on the Desktop to Dailup.lnk

I can open the shortcut using the previous Dialog Box but when i try after that to launch it with ShellExecuteEx i get the following error :

The parameter is incorrect.

In a messagebox.

Do you have any idea why i am getting this error?

Code:

---

        SHELLEXECUTEINFO        sei;
        ZeroMemory( &sei, sizeof( sei ) );
       
        sei.cbSize                = sizeof ( SHELLEXECUTEINFO );
        sei.lpFile                = ofn.lpstrFile;
        sei.lpVerb                = _T("open");
        sei.fMask                = SEE_MASK_NOCLOSEPROCESS | SEE_MASK_NOZONECHECKS;
        sei.nShow                = SW_SHOWNORMAL;

        CoInitializeEx( NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE ); // Incase that "COM single-threaded apartment (STA) type" is needed

        ShellExecuteEx( &sei );

Try setting the verb to NULL.

As you are trying to launch a shortcut (.lnk file) the OS should then search the reg for the correct association and run the required process/application based on the target of the shortcut.

Thanks, it worked flawlessly :D
