Sent DDE Messages

  • Article

Overview

The DDE protocol uses the MONMSGSTRUCT structure to post DDE messages. DDESpy displays the following information from this structure:

  • Task

  • Time

  • Handle of receiving window

  • Transaction type (sent)

  • Message type

  • Handle of sending application

  • Other message-specific information

The following example shows a typical DDESpy display of DDE message activity:

Task:0x8df Time:642402 hwndTo=0x38dc Message(Sent)=Initiate:
        hwndFrom=9224, App=0xc35d("Server")
        Topic=*
Task:0x94f Time:642457 hwndTo=0x2408 Message(Sent)=Ack:
        hwndFrom=9396, App=0xc35d("Server")status=c35d(fAck
        fBusy )
        Topic=Item=0xc361("System")
