window-messages

MAIN FORM The main form receives windows messages sent by the RDM LogData(‘DataToLog’) Because windows messages are used they have the following attributes Received messages are Indivisible Received messages are Queued in the order they are sent QUESTION: Can you Suggest a better way doing this without using windows messages ? MAIN FORM CODE const UM_LOGDATA = WM_USER+1002; type TLogData = Record Msg : TMsgNum; Src : Integer; Data : String; end; PLogData = ^TLogData; TfrmMain = class
