Strange Error during execution

[Paolo Ponzano]

Hello, I'm getting this error: Run-Time Check Failure #2 - Stack around the variable 'UniqueID' was corrupted. Here's the function that generates it __declspec( dllexport ) BYTE* LaunchMe(BYTE* id) { SERIAL *serial=NULL; BYTE ProductID[BUFFER_LENGHT]; BYTE UniqueID[16]; char *ProductID_Processed=(char*)malloc(BUFFER_LENGHT); serial=(SERIAL*)malloc(sizeof(SERIAL)); memset(serial, 0, sizeof(SERIAL)); memset(&ProductID, 0, BUFFER_LENGHT); memset(&UniqueID, 0, 24); getHardDriveComputerID (serial); if ( GetProductID(ProductID, BUFFER_LENGHT) == false) return false; ProductID_Processed=ProcessProductID(ProductID, BUFFER_LENGHT); if (ProductID_Processed == NULL) return false; CalculateUniqueID(serial->serial, ProductID_Processed,UniqueID); memcpy(id, UniqueID, 16); return NULL; } Which is the cause of that error? What "around" means?? I get this error some other time also, and google wasn't able to help me, thanks in advance Paolo

Don't know whether this is the same as your case, but I once had a similar problem and it turned out the cause is because of stack overflow. Maybe you can check whether you have enough stack space to hold ProductID? What's the value of BUFFER_LENGTH?

Hi, The problem is pretty straight forward. You are declaring UniqueId[16] and in memset you are using 24. Change it to memset(UniqueID, 0, 16); That should solve the problem. Regards, Mahadevan
