Some issue of my application

Hi yee,

I've got a problem. I want to build an application which can be running
one instance at one time. A know a solution but it works only when the
application was loaded into the memory. Is there any chance to provide
this, I mean the code must be compiled under some extra circumstances.
For example the operating system, Windows95 can recognise that this
application can be run in one instance at one time.

Any help regarded,

By issue I assume you mean instance?  You want to restrict your program so that only one copy can be running.

I also think you want to restrict it so that only one copy will run anywhere on a network at any given time.  Is this correct?

Its difficult to understand the question.  Are you actually writing it for Windows 95?

try this. write it in the dpr file.
var FWindow: THandle;
  FWindow:=FindWindow('TfMain',write here the caption of the form or nil);//find a window by the class of the form, in this case is TfMain
  if FWindow<>0 then

  Application.CreateForm(TfMain, fMain);
this is not an elegant solution but...
