I have verified that passing the argument 2 is different from the number
1, or 3, or 4 -- so there is, apparently, an undocumented value that
alters CreateObject behavior.
As previously mentioned, I have not gotten the GetObject technique to
work on Win64 with a Windows Script Component file (.wsc) containing
VBScript and JScript code. I then tried registering the file with the
command
RegSvr32.exe HomerJax.wsc
To my surprise, that seem to work, except that there now seems to be a
threading problem with the operation of the COM server from a JAWS
script. Some methods of the COM object work fine, but in other cases,
the JAWS script returns from the method call before it has completed.
At first, I thought the JScript method was aborting due to an error, but
when I use a method of the COM server to display the return value just
before exiting the method (where control would normally return to the
JAWS script), the return value is actually correct. The JAWS call
returns right away, however, with a blank value.
If anyone has additional ideas for debugging this, please let me know.
