Progressbar in DLL

Can anyone tell me how I can create a Delphi DLL with a progressbar in it that can be called by external programs. What I am really asking is how do I make the application the parent of the progressbar? please see further comment below.

TIA

Slavak

just place it on form and show/hide the form when you need

Does your dll only contain a progressbar which you want to show on another control or form of the calling application, or does it contain a form which displays the prog.bar?

The idea is the progress bar ( on a form ) can be compiled into a DLL then i am using a completely different programming language to use the DLL. I want the new application to be able to pass a window Handle and then the progress bar to use this window as a parent - so if I alt Tab out of the application the progressbar goes with it

Many thanks for your help with this

Edited text of question.

Sorry, I cannot understand your problem.

Just create form, place progressbar on the form.

Make three functions :

procedure ShowProgressBar;
Begin
ProgressBar.Position := 0;
Form1.Show;
End;

procedure SetProgressBar(Pos, Max : Integer);
Begin
ProgressBar.Max := Max;
ProgressBar.Position := Pos;
End;

procedure HideProgressBar;
Begin
Form1.Hide;
End;

export the functions from your dll.

You can add some changes, if you want have number of progressbars in same time, or "Cancel" button on it.
