Here's a better illustration of the arrows not appearing initially. And as I refresh the Firefox view, I'm seeing the same issue ... View more

This also happens once in Google Chrome on the first time, but not on refresh. I've been noticing that the tool bar is not consistently appearing in IE7 (we're not able to upgrade to 8 yet). Sometimes, the arrows to move the icons do not appear until I move the cursor over the map (filling in the X,Y coordinates) or resize the window. This is very intermittent. ... View more

It's coming up with a different error now. The message Error #1009 flashes briefly, then disappears. The empty error window remains. This happens on Firefox 3.6.6 (upgraded last night) every time I refresh it and once on IE7, but not on subsequent refreshes. ... View more

Ken,    Thanks for the headsup I was able to get this error in IE 7 when I got home on a slower internet connection...? IE 7 must be do things in a strange order as the offending line of code what just a simple line telling the graphicsLayer  to be visible. Hum... Anyway I have put some checks in there now to be sure the graphicsLayer for all my widgets that use graphicsLayers are not null before I try to use them. Hi Robert, I was getting this on Firefox 3.6.3 with Flash 10,1,53,64 and a high speed connection ... View more

Are you familiar with Cartographic Representation? This will allow you to have dashed lines around polygons that share a common boundary. Take a look at the Help files ... View more

In the extension I developed, I used the same ESRI example as you did. One thing that is different between our code is when you initialize the variable m_extensionState. When you initialize it, you're also setting it to disabled. In my code, the variable gets set to either disabled or enabled in the State Property. ... View more

As you state, OnCreate is only fired when the command is created, whereas Enabled is fired continuously (which is also why you shouldn't have any extensive code in that subroutine). This will react to any changes in the environment, like enabling the extension. ... View more
