Monitoring Callbacks

The DDE protocol uses the MONCBSTRUCT structure to pass information to application callback functions. DDESpy displays the following information from this structure:

• Task
• Time
• Transaction type
• Exchanged-data format, if any
• Conversation handle
• String handles and their referenced strings
• Transaction-specific data

The following example shows a typical DDESpy display of callback activity:

Task:0x8df Time:2882628 Callback:
       Type=Advstart, fmt=0x1("CF_TEXT"), hConv=0xc24b4,
       hsz1=0xc361("System") hsz2=0xc4df("xxcall"), hData=0x0,
       lData1=0x83f0000, lData2=0x0
       return=0x0
