How to set the private directory to the applications' subdirectory (Views: 100)


Problem/Question/Abstract:

I'm wondering how one can set the privatedir. I don't mean in my program, but just so I know where the temp files go. Does the BDEcfg program do that? If so, where? I'm using BDE 4.0

Answer:

Your program sets the private directory, it's not in the cfg. If you don't set it in your program it defaults to the apps directory. If your app resides on a server in a multiple use environment this is not what you want. I add the following code to all my apps (I also limit my apps to one instance):

s := ' C:\AZPC\PRIVATE\' + ChangeFileExt(ExtractFileName(Application.ExeName), '.');
if not DirectoryExists(s) then
begin
  ForceDirectories(s);
  if not DirectoryExists(s) then
    ShowMessage('Unable to find and/or create the ' + #10 + s + #10 + ' directory '
      + #10 + ' the program will run, but not be fully functional.');
end;
Session.PrivateDir := s;

This sets the private directory to the exe name subdirectory on the C: drive.
