CodePudding user response:

add a breakpoint debugging information

CodePudding user response:

Do the hook DLL had better not use MFC,
If there is need, plus the MFC initialization,

CodePudding user response:

Yourself with the log output to see which line error, this assertion errors should be handle to 0

CodePudding user response:

Collapsed in the pop-up dialog box, press the corresponding button to enter debugging press Alt + 7 key to view the Call Stack, namely "the Call Stack" from the inside to the following out of from the inner to outer function Call history, double-click a row to the cursor to the Call of the source code or assembly instruction, don't understand when double click on the next line, until we can read ,

But I saw "the call stack" didn't find out what's wrong, or I send the code to you help me look at you?

I log a look line error, this assertion caused mistakes should be handle to 0

Indicated in the error of 196 lines is appcore CPP in this ASSERT (AfxGetThread ()==NULL), can you tell me the handle to 0 if I should change?

CodePudding user response:

refer to the second floor Saleayas response:

I have added the initialization,,,

Thread has quit, the thread handle operation?
Some retry in the call stack, find your own code from the stack
