How do I fix ERROR_INVALID_BLOCK?
1. Ensure the target function is large enough to be detoured
This ensures that the function is large enough for the detour to attach properly and prevents the ERROR_INVALID_BLOCK error from occurring.
2. Initialize the target function pointer correctly
This avoids the ERROR_INVALID_BLOCK by ensuring that the function pointer is set up correctly before attaching the detour.
3. Use DetourTransaction API correctly
Here’s an example of using DetourTransaction API:
This ensures that the detour is part of a transaction and helps in orderly attaching and detaching of detours, preventing errors.
4. Check for memory availability
Ensuring that there is enough memory available prevents the ERROR_INVALID_BLOCK error due to memory constraints.
5. Verify the integrity of the function being detoured
Ensuring the integrity of the target function prevents errors related to function size or corruption.
6. Handle special cases in automation calls (VBA/COM)
For example, using the correct type in a VBA call:
This method ensures that the argument types match the function’s expectations, preventing block errors.
By following these solutions, you can effectively address the ERROR_INVALID_BLOCK error in your detour operations and ensure smooth and error-free function hooking. Always remember to check your function sizes and memory availability to prevent such issues in the future. You can also learn how to resolve a similar issue,CNSS_FILE_SYSTEM_FILTER.
