Exception when I use the TsFileOpenDialog;
I make the call, as in the example below.
When I make selection the file and click in botton OK, an Exception is generated:

“First chance exception at $776742EB. Exception class EAccessViolation with message 'Access violation at address 00000000. Read of address 00000000'. Process MyProject.exe (916)”

Example my Code:
FileOpenDialog1.Execute;
EdtFile.Text: = FileOpenDialog1.FileName;

I changed the component to TOpenDialog and occurs the same error!

But, when I created a new project and did not use the components “Alpha Controls”, but the component TOpenDialog, works perfectly!

I am using the version 6.30 (Last version) – version 6.22 also has the same problem!
Operating System “Windows Vista Home SP1”
Already tried the “Windows XP” that same problem occurs.

I modified a property of TsFileOpenDialog – Options.ofNoValidate: = true, and the problem was solved!

That is the cause of Access?

I think that old-style file dialogs have a problem with characters validating under Vista. Could you make a new project with standard dialog and try him with and without the ofNoValidate property…
