As already explained (Main)Form and Application are two different things. Since Delphi 2007 there is another behavior to note. In dependency of Application.MainformOnTaskbar you are able (or not) to get the handle via Findwindow. A little snipplet to show the different behavior var FW_ah, FW_mfh, ah, mfh: THandle; Procedure Display(OnTask: Boolean); begin Application.MainFormOnTaskbar:= OnTask; ah:= Application.Handle; mfh:= MainForm.Handle; FW_ah:= FindWindow(PChar(Application.ClassName), PChar(Application.Title)); FW_mfh:= FindWindow(PChar(ClassName), PChar(Caption)); Showmessage(Format('ah:%d FW_ah:%d - mfh:%d FW_mfh:%d', [ah, FW_ah, mfh, FW_mfh])); end; begin Display(true); Display(false); end. • Application.Handle is the window handle for the hidden window associated with the global Application object.

• FindWindow('TForm1', 'Form1') will return the window handle of a top-level form in your application. These are indeed not the same thing. You could, I suppose, use Form1.Handle instead of Application.Handle. However, you would need to be wary of window re-creation. Frankly this doesn't sound like the best way to do inter-process communication. Perhaps you might consider sockets or named pipes.
Circuit for Serial communication between two Arduino Boards Step 2: Code for Sender Arduino This is code for Sender Arduino Board. First, initialized a string with data 'Hello'. Psytrance Samples Rapidshare Movies.
In setup, the Serial Monitor is begun at 9600 Baud. In loop, sent the data to receiver Arduino using Serial.write. For more information about Serial.write, Step 3: Code for Receiver Arduino This is code for Receiver Arduino Board. First, initialized a blank string to store serially received data. In setup, the Serial Monitor is begun at 9600 Baud.
In loop, received the data from sender Arduino using Serial.readBytes. For more information about serial. Fc Barcelona Vs Real Madrid Full Match Download there. read, Step 4: Upload the code to Arduino Upload the code to the sender and receiver Arduino Board. Make a circuit as per the given diagram after uploading code. Hello will be transmitted from Sender Arduino to Receiver Arduino. You can transmit your data or variable like this. For information about uploading code to Arduino Board, Note: If it shows error while uploading code to Arduino, disconnect the connection between Arduino and try to upload program on it.
