I have an exe that loads a a form A in a DLL. Form A, in turn loads
Form B. None of the forms are modal. So, my users can access Form A and
Form B without having to close any. Now, if they close Form A, for some
reason, Form B disappears. It is still in memory but just disappears.
BringToFront, visible = TRUE, show, nothing works. Any thoughts and
assistance are greatly appreciated.

I am using the following code (simplified, of course):

// in EXE
DLL_LoadFormA( Application.Handle ); // Applcation.Hanlde is the exe's
handle

//in DLL
procedure DLL_LoadFormA( exeHandle: HWnd );
var
frmA : TformA;
begin
if exeHandle = 0 then
exeHandle := GetActiveWindow;
Application.handle := exeHandle; // DLLs appl...handle

//create form A
frmA := TFormA.Create( Application );
frmA.Show;
....
end;

//in formA's code
procedure btnClick( Sender: TObject );
var
frmB: TFormB;
begin
frmB := TFormB.Create( Application );
frmB.Show;
end;

Please help!! Smile
