It depends on what your addins do.  First of all, make sure you're getting your references correctly.  For instance, if you want to do something like add elements to the graphics container then don't get the graphics container reference from something like IMxDocument.ActiveView.  The ActiveView property returns a map while in Data view and a page layout while in Layout view.  Also, you can simply disable your addin while in the incorrect view.  If it only works in Data view then check IMxDocument.ActiveView to see if it is a page layout and disable your addin if it is. ...

This is more than likely an operating system issue rather than an ArcGIS 10 issue.  Typically, users do not have Write privileges on the Program Files folder.  Therefore, applications should not write to folders under Program Files.  You will need to write to another location, such as the user's profile application data folder or the common application data folder.  Older operating systems, such as Windows XP may not have this limitation but you should write your application to be as OS neutral as possible. ...

I'm using ArcGIS 9.3.1 and the only Web coordinate system I see is WGS 1984 Major Auxilliary Web Mercator, which is 102113.  If you're using ArcGIS 10, then I would verify that the constant you're using is valid by looking it up in the developer help. ... View more

What coordinate system are you trying to create?  I tried finding 102100 in the developer help and it doesn't appear to be a valid constant. ... View more

The UI that you see when you use a geoprocessing tool is generated from the parameters used by the tool.  The tool is simply something that someone wrote to perform a task.  The inputs it takes do not necessarily match the parameters required by the underlying ArcObjects methods that it may use.  In this case, it is most likely something that was added to make the tool easier for the user to use.  You can specify the value in whatever units are available and the tool will do the conversion before passing the value to the ArcObjects method.  When calling the ArcObjects method in code, you have to pass in the value in whatever units it expects. ...

There are several things that could cause an issue here. Dim pWorkspaceName As ESRI.ArcGIS.Geodatabase.IWorkspaceName Dim pWorkspaceFactory As ESRI.ArcGIS.Geodatabase.IWorkspaceFactory 'Set up new database pWorkspaceFactory = New ESRI.ArcGIS.DataSourcesGDB.AccessWorkspaceFactory pWorkspaceName = pWorkspaceFactory.Create("C:\Temp", "foo.mdb", Nothing, 0) As already mentioned, use the Activator class to create an instance of the workspace factory.  Also mentioned, the directory C:\Temp must already exist.  Additionally, the database foo.mdb should not already exist.  I don't think the Create method will overwrite an existing database.  The final parameter to Create is a window handle.  Since you're calling this method from a Windows Form, you should be passing in the handle of that form (Form.Handle.ToInt32).  In cases where the code is not called from a form, use the application's handle (IApplication.hWnd).  You also need to have write permissions on the Temp directory.  I can't imagine why you wouldn't but if the code is still failing you might want to make sure. ...

You should release the feature objects you're using inside the loop in each loop iteration.  The ones I see are fSource, fTargetNew and f (at least it looks like f is a feature object).  Call ReleaseComObject on these feature objects inside the loop just as soon as you're done with them just like you do for cursor objects. ...

You're calling Refresh on the document's active view.  If the document is in Layout view then this will refresh the layout and not the map inside of the map frame.  If the document is in Data view then this will refresh the map in the table of contents that is currently active.  If you are calling this code while in Data view and the map that contains the layer is active then this should work.  Otherwise, you will need to get the appropriate active view reference before calling Refresh. ...

I don't work directly with SDE data all that much but if your data is versioned then shouldn't you be specifying the version you want to edit when you open the workspace?  Your code appears to be opening the default version: _ps.SetProperty("VERSION", "SDE.DEFAULT"); ... View more

just found a workaround: I switch to the dataView and set the center point of the extent there (using the following code), then switch back to the LayoutView:             Dim centerPoint As IPoint             centerPoint = New ESRI.ArcGIS.Geometry.Point             centerPoint.PutCoords((left_x + right_x) / 2, (upper_y + lower_y) / 2)             Dim activeView As IActiveView             activeView = pMxDoc.ActiveView             ' get the active view�??s extent             Dim ext As IEnvelope             ext = activeView.Extent             ' set extent center point:             ext.CenterAt(centerPoint)             ' set the extent             activeView.Extent = ext             activeView.Refresh() Cheers, Johannes There's no need to switch to data view in order to run this code.  If you change this line: activeView = pMxDoc.ActiveView To this: activeView = pMxDoc.FocusMap then it will work the same in layout view.  An active view can be either a map or a page layout.  The ActiveView property returns whichever one is appropriate for the current view.  If that's not what you want, then you set your active view reference using either the FocusMap or PageLayout properties.  Of course, if your layout contains multiple data frames and you want the map inside a data frame that is not the active data frame then you will need to get the frame element from the graphics container and get your map reference from that element. ...
