Well, when I debug the DLL in VC++, it stops with the error report I mentioned when the programm runs into the line: "100090E6 call @ILT+195(checkparam_4_Margin) (100010c8)", and when I click 'OK' to close the error dialog box, the arrow points to the line: "10004B51 mov byte ptr [ecx+eax],0FFh", and can not run further.
*The 'checkparam_4_Margin' is a function in the DLL, but not an exported one.
*I have tried to leave the 'checkparam_4_Margin' out, but it still stops somewhere like: '
1000908D call @ILT+195(psResult) (100010c8)' . The 'psResult' is also a function in the DLL, but an exported one and called in VB.
*Then I left the 'psResult' out of the code, the error still happed in somewhere else.
I don't know how to understand the lines in the debug environment. And I don't know what to do next.
Thank you for your help.
