I would like my DLL to comunicate with my application in any way. Windows
message api function seems like a good idea. This is the code for receiving
a message on date time change. When the message on date time change is
received, an event (or function) is triggered. I would like to "trigger" a
handler function in my application from my DLL, and pass some parameters if
possible.
Something like this should be in my application (this works for date/time
change i would like a handler for messages from another application, not
date/time)!
class TMyForm : public TForm
{
private:
// declare a handler function for your message
MESSAGE void __fastcall WM_TimeChange(TMessage &Message);
BEGIN_MESSAGE_MAP
// associate your handler function with some message
VCL_MESSAGE_HANDLER(WM_TIMECHANGE, TMessage,
WM_TimeChange);
END_MESSAGE_MAP(TForm);
};
// in your source file
// define the handler function
MESSAGE void __fastcall TMyForm::WM_TimeChange(TMessage &Message)
{
ShowMessage("Date or time has been changed!");
}
Now I need the code to send a meessage from DLL (or another application) to
my application. (I think it's the PostMessage method, but I'm not sure)!
I hope this clears what I want the code for.
Thanks,
Luka.
