New to ArcObjects 10

NeedHelp — Tue, 23 Jul 2013 17:51:46 GMT

Having trouble creating custom buttons for 10.0 from 9.3.
I know most of my code will work, but when I run the snippits:
GetMxDocumentFromArcMap & GetActiveVewFromArcMap both return Nothing.

So it's impossible to do anything further when you can't get a valid reference to the MxDoc or Active view.

My previous code used to have:
Private m_application As IApplication
But in 10.0 I get an error with that line and changed it to:
Private m_application As ESRI.ArcGIS.Framework.IApplication

Could somebody post some sample code or sample project to help me get started??

Thanks

Still hoping to get a bit of help.

Even when I use the Snippet "GetMxDocument from ArcMap" Nothing gets returned.
Is there something basic I'm missing??

What is the value that you're setting m_application to? If you're creating an Add-in, then you can use

Private m_application As ESRI.ArcGIS.Framework.IApplication = My.ArcMap.Application

Private m_application As ESRI.ArcGIS.Framework.IApplication = My.ArcMap.Application

WOW... your awesome!! That was exactly what the problem was.
Thanks so much.

Wonder if it's a common issue for new to '10 programmers, or just me 🙂
