Can anyone advise - I have a class which I want to convert into a DLL.
The class monitors the position, window state/size of another application
which is running. Whenever the monitored application is resized, is
minimized restored or maximized the class raises an event.
I think I know how to map the class's functions in the DLL but I cannot see
how I can do the events.
I considered using Window messaging but that can only pass a message number
whereas I would prefer to pass parameters with the event. I also couldn't
figure out how to implement it in the DLL anyway. If I assign the class
event to a procedure which posts a windows message I get a compiler error
"Method Pointer and Regular procedure" on the line where the assignment is
made.
I have done the assignments in the DLLMain routine. e.g
ideWindowProp := cWinProperties.Create(MONITORPROG,20);
wm_notify_WinProp_Num := RegisterWindowMessage('WM_NOTIFY_WINPROP');
with ideWindowProp do
begin
On_ApplWindowChange := AppWinChange;
// get errors on each assign line
On_MainFormChange := MainFormWinChange;
On_EditWindowChange := EditWinChange;
On_ExplWindowChange := ExplWinChange;
On_ResultsWindowChange := ResultsWinChange;
On_Appl_StateChange := AppStateChange;
end;
Question I have is am I going about it the right way or is there a better
way? If this is a reasonable way what am I doing wrong.
