[mapguide-users] MAPNAME & Map.Open

[Mark Pendergraft]

Okay regarding number 1, I was hoping you would provide a code snippet
or a little more info.  I'm pretty new to ASP and I'm having a really
hard time making javascript and vb.net in ASP jive, as well as just
having a hard time with javascript in general.

Regarding number 2....Thank you so much!  I knew it was something
stupid, it never occurred to me that the username/password would crash
the map.open procedure.

Thanks again for the help thus far.

-Mark P.

Hi Mark,

1) I use the javascript method and store the map name in a hidden form
field
so it can be picked up in the Page's Request.Form collection

2) I see a few problems with this code,

- You have two sessionid variables with lower and upper "s" casings.
- You are new'ing a MgUserInformation object with username/login instead
of
the sessionid. This is probably the cause of the failure, becuase
MAPNAME is
tied to your session id. If you want to use Map.Open with MAPNAME you
have
to open the MgSiteConnection with a MgUserInformation object that has a
session id, not user/pass.

Hope that helps.

- Jackie
