problem zooming when window minimized

JeffRogholt — Wed, 08 Oct 2014 13:03:44 GMT

We're using Developer Kit 10.1 in a vb.net win forms app. The app listens for messages in the message queue. The message contains x/y. When a message is received, the map goes to the location. When the form is visible/open the zooming works but when form is minimized it does not zoom to the correct location.

These are the steps to reproduce the issue:

Minimize the form

Send a message containing x/y

Restore/open/maximize the form and the map is in the wrong location

Here is a snippet of code:

Private Shared Sub ZoomMap(ByVal map As AxMapControl, _

ByVal pt As IPoint)

Dim mapExtent As IEnvelope

mapExtent = map.Extent

mapExtent.CenterAt(pt)

map.Extent = mapExtent

End Sub

Is this a bug? Is there another way (not using CenterAt) to get the expected behavior? Any suggestions or help is appreciated.

Thanks,

Jeff

I tested your function with 10.1 and windows forms app with scenario zooming to a specific location using timer.
I press the Zoom button and minimize the window, then maximize it again and it zooms to the right location.
I found no problems with that.
Also you can check this zoom function:
