Monitoring Posted DDE Messages

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 or posted)
• 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")
