Re: I need some help : exception in Type Browser

Hi Tanveer and Josh

(first, I couldn't spot Tanveers direct mail adress, but I found this,
in a "Comments" header in the mail: [email protected], so I assume this
is the mail address I should CC to? - I assume CC's disappears in the
mails after they have been through the Jawin-mailing list machine?)

Date support have been added recently, and is available by checking out
the CVS-head as described here:
        http://jawinproject.sourceforge.net/jawindeveloper.html

About the exact mapping of types from Java to native Variant types:
"If you need detailed control of how Jawin converts Java types into
native Variants the javadoc for Variant.WriteObject() must be consulted.
But please notice that the IDispatch coercion mechanism handles
scenarios where the VT_TYPE of a parameter is a not a 100% fit to a
method signature or property. Therefore there should not be any problems
by setting eg. a property requering unsigned int's with either a long or
an int." (from some of the most recent documentation, that is only
available in the CVS - docs/jawinuserguide_dispatch.html).

I have updated the documentation on threading issues too, so I will
suggest that you re-read section 6 in the jawinarchitecture.html
document from the CVS too.

Hope this helps you further
