Re: [BLACKBOX] AW: [BLACKBOX] Trouble with Windows 7 Professional 64 Bit but not with 32 Bit

Helmut,

I guess this would only be necessary if you would like to compile your program both as 32 and 64 bit from the same source.

res := RegOpenKeyEx( ... sam + KEY_WOW64_64KEY ...)
IF res = NO_ERROR THEN => Access a 64-bit (or 32) key from BB32
   (* use this sam on child keys *)
ELSIF res = ERROR_FILE_NOT_FOUND THEN
   res := RegOpenKeyEx( ... sam + KEY_WOW64_32KEY ...)
   IF res = NO_ERROR THEN => Access a 32-bit (or 64) key from BB64
      (* use this sam on child keys *)

Will we ever have a 64bit BlackBox?

Brgds,
Koen.

        Dear Koen,

         

        thank you for the quick response. Your answer solves this problem.

         

        There is a similar problem with enumerate all keys. The website says it should be done with two passes.

        Do have a solution for it too?

         

        Regards

        Hello Helmut,
        
        The problem can be solved by specifying in RegOpenKeyExW that you are accessing a 64bit registry from a 32bit program.

        CONST sam = WinApi.KEY_QUERY_VALUE + BITS(100H);

        More info here <http://msdn.microsoft.com/en-us/library/windows/desktop/ms724072%28v=vs.85%29.aspx> and here <http://msdn.microsoft.com/en-us/library/windows/desktop/aa384129%28v=vs.85%29.aspx> .
        
        Best regards;
        Koen.
        
        PS I have been working on Xy lately - do you want a preview?

        Dear BB Users,

         

        I work with BlackBox since 15 years

        and with Windows 7 Professional 32 Bit since 4 years successfully.

         

        3 month ago I changed to Windows 7 Professional 64 Bit and the trouble starts.

         

        My subsystems Dos & Benchmark don’t work well any more.

        Now I isolate my first problem in a small test program (see below).

        This program works with 32 bit but not with 64 bit.

         

        Does someone know how to solve this problem?

         

        With best regards

        Helmut Zinn
