Callbacks

Overview

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
