Mapguide Map 6.5 Method cannot be invoked at this time
Hello,
I'm using mapguide 6.5 inside a ClickOnce windows application and have had no problems until just this week. Here's what's going on:
3 test computers are working fine, but 2 test computers are unable to access any methods associated with the map.
All of the following will throw an error "Method 'zoomInMode' cannot be invoked at this time":
this.MGMap1.isBusy();
this.MGMap1.panMode();
this.MGMap1.se lectMode();
this.MGMap1.zoomInMode();
this.MGMap1.zoomOutMode();
Th e map is not null. Any suggestions?!?
thanks!

Oh... and I am connecting to an Oracle Database and this connection has been tested & working properly.
As long as all the ODBC drivers are the same on all systems, your DB connectivity will be fine. Yes, IE7 upgrades have caused MANY MANY incompatibilities, especially with niche programs that use particular calls that average browsers don't. One of the ways you can test this is to go into INternet Settings in control panel and DECREASE the security level to "average" which was the way IE6 was set. IE7 puts it up to high or maximum, and that breaks a lot of apps, especially ones connecting to servers like Oracle.
While in the Internet options, go through ALL checkboxes to enable or disable features of IE, comparing a working install of IE6 with how the IE7 system is now set. More than likely, you will find the problem there.

I fixed the problem. The the Isolated property on the dll had been set to False. Once it was changed, the control behaved correctly.
Thanks for your help!

More information on the active X MapGuide Map Control:
The built in toolbar with zooming and panning buttons works fine on the map. I have been hiding this toolbar because it is ugly and using my own buttons by calling the methods described above. Accessing the methods of the map programmatically is what is causing the error.
I've read a few articles describing how a IE update has been causing problems for active X controls. However, the control is in a windows ClickOnce app and not a web app so their fix won't work for me. I'm not sure if this is truly the cause but it's an idea... any suggestions?
