I'm trying to port my WDM driver to Vista RC1 but I crashes during driver initialization. Using Windbg, I narrowed it down to a RtlIntegerToUnicode system call. This function works perfectly in W2K or XP. Did MS do anything different in this function? I also can't get my KdPrint statement to be displayed.

In the RtlIntegerToUnicode system call, the Unicode String was initialized using the address to a constant character string (L" "). Apparently, Vista does not like for you to modify the address pointed to by L" ". Once I modified the code to allocate memory for the Unicode String, Vista didn't crash anymore. My driver is still not loading (see my other post) though. John >> Stay informed about: Problems porting WDM to Vista RC1
