Debug Assertion Failed in MFC140d.dll - How to Debug and Troubleshoot

This error message indicates that an assertion has failed in the program. Assertions are used in programming to check for specific conditions or assumptions and terminate the program if they are not met. In this case, the assertion failure occurred in the file "afxwin1.inl" at line 24. To debug the application, you can click on the "Retry" button, which will launch the debugger and allow you to investigate the cause of the assertion failure. The debugger will stop at the line of code where the assertion failed, and you can examine the program state, variables, and call stack to identify the issue. You can also refer to the Visual C++ documentation on assertions for more information on how to handle and troubleshoot assertion failures in your code.
