IPC Issue of Windows 7 (32bit)

Post by lovenamu »

We have supplied our customer with our security software that uses madCodeHook library to hook StartDocW() API.
The hooked program is IE(Internet Explorer)8, which executes an active-x program in some html pages.
The active-x program is used to print some reports of the customer.

In the callback function of StartDocW ( StartDocWCallback ), we call SendIpcMessage() API to communicate with our stand-alone win32 program.
However, the SendIPCMessage() API has no response in the the StartDocWCallback of the activeX.
( Other hooked programs have no such problem. )

We have added some debugging codes to the madCodeHook C source for producing logs (we have bought the enterprise license).
Could I send you the log-generating-code-added madCodeHook source & the generated log file,
and Could you help this problem?

Thanks in advance.

Hmmmm... Just to be safe: Are you using the latest madCodeHook version? That would be 3.1.6. Usually ActiveX is just a dll loaded in the IE process. Or do you run IE8 in a special security setting which creates a new process for ActiveX execution?
