Question

I have checked 100% I am closing all handles on a file I recently created. But when I call ‘opendialog.execute;’ the dialog pop up as usual but on the mouse over hint of a recently created file the entire thing crashes with a out of bounds error.

I know this is not any of my out of bounds as if I open the file without causing a (onhint) event there is no problem and hardcoding a list of filenames for testing showed that there was nothing wrong with opening or saving a file. Its purely on the onhint event of the open dialog. Like I said if I am quick or I use arrow keys there is nothing wrong with my program.

Whats more interesting is that it doesnt even happen 100% of the time about 70% which has led to me thinking I have fixed it several time if not only for a short amount of time. Does anyone know what could be happening? And if not how can I disable the onhint event?

as aked for the code not that helps at all

OpenDialog.execute;    // crashes here if fileexists(form1.OpenDialog.FileName) then       form1.Address.Text:=form1.OpenDialog.FileName; 

and the error link text

EDIT: ok i have some new information a new instance of opendialog still has the same issues. and more interestingly i seem to have solved the 30% issue its on hint of a file with a double tag for example ‘test.jpg.enc’ the thing is its fine with it the first time it runs, and it only crashes on hint of these encoded files, but only if i have encoded that file white the applicatuion has benn open. for example if i encode it,, then try to decode and it crashes.. i can run it again and decode it fine,, but there is no problem with decoding and then encoding in one instance of the aplication.

The solution for this was to use activeX, it appears there was a bug intorduced after SP2

uses ActiveX;

initialization OleInitialize(nil);

finalization OleUninitialize end.
