Problem 1. I want the user to select a directory (AKA folder), not a file. I can do this with TOpenDialog. Actually this dialog serves to select a file, but when I strip the last part from OpenDialog->FileName, the directory remains. I do not really like this method, since it confuses the user. Furthermore it is impossible to select an empty directory. Any solutions? Problem 2. The user runs my program and selects a directory with TOpenDialog. He closes the program, reboots the computer and restarts the program. When he starts TOpenDialog, I see that it has remembered the directory, although I wrote no code to remember it. OpenDialog->FileName is empty before TOpenDialog is started. Where is this data stored? Can I access this data without having the user start TOpenDialog? -- José Back to top Alan Bellingham Guest Posted: Mon Apr 24, 2006 10:03 am    Post subject: Re: A directory and TOpenDialog Hans Galema <notused (AT) notused (DOT) nl> wrote: Quote: José wrote: Where is this data stored?

Seems interesting, but SelectDirectory() has two versions, and they say this, although the header in Filectrl.hpp is exact: E2285 Could not find a match for 'SelectDirectory(AnsiString,WideString,AnsiString *)'. E2285 Could not find a match for 'SelectDirectory(AnsiString *,TSelectDirOpt,int)'. I cannot find SHBrowseForFolder() in the help file. -- José Back to top Minas EnRethy Guest Posted: Mon Apr 24, 2006 1:03 pm    Post subject: Re: A directory and TOpenDialog ?

Hi Jose, 1 . borland.public.cppbuilder.vcl.components.using Date: Sun, 19 Feb 2006 Subject: TOpenDialog selecting directory Quote: Problem 2. When he starts TOpenDialog, I see that it has remembered the directory, although I wrote no code to remember it. 2. You can use InitiaDir property of TOpenDialog or set ForceCurrentDirectory = true; somewhere before call OpenDoalig->Execute() if ForceCurrentDirectory is true, the dialog opens with the current working directory displayed.

When he starts TOpenDialog, I see that it has remembered the directory, although I wrote no code to remember it. OpenDialog->FileName is empty before TOpenDialog is started. Do be aware that this is related to Windows, and varies slightly with the version of Windows in use. It is not a failing of TOpenDialog itself, which merely wraps the API function. -- Timothy H.

It is fine that the original directory is retained, but I want to know what it is before OpenDialog is executed. Quote: Where is this data stored?

The Registry seems to have no relation between program and directory, but merely between extension and directory. -- José Back to top Hans Galema Guest Posted: Tue Apr 25, 2006 8:03 am    Post subject: Re: A directory and TOpenDialog José wrote: Quote: WideString Root= "C:\\" ; You omitted my reply to use AnsiString only.
