bluebearr Posted July 17, 2007 Share Posted July 17, 2007 I'm trying to make a call to MoveFileExA to delete an inuse file on reboot. Here is my code:$delfile = "" $MOVEFILE_DELAY_UNTIL_REBOOT = 4 $result = DllCall("kernel32.dll", "short", "MoveFileExA", "str", "C:\temp\Test.txt", "str", $delfile, "int", $MOVEFILE_DELAY_UNTIL_REBOOT)If I set $delfile to a string (like 'C:\temp\Test2.txt'), the HKLM\SYSTEM\CurrentControlSet\Control\Session Manager key gets updated as desired. However, I can't figure out how to pass a NULL to the function. I've tried an empty string, Chr(0), and a dimensioned but empty variable. None of these worked.BTW, I'm aware that I can edit the registry value directly, but I've run into problems with this in the past with other tools (*cough* VBScript *cough*), so I would like to use the API call if possible.Any ideas? Thanks! BlueBearrOddly enough, this is what I do for fun. Link to comment Share on other sites More sharing options...
