[GIS] How to close the current mxd document through arcmap add-in

add-inarcmaparcobjectsc

First, I open a mxd document named A in arcmap, then i use my add-in to generate another mxd document named B,

then I use

 ArcMap.Application.OpenDocument(arcmapMapFileName);

to open the document, but the document does not display normally, it has both A and B's layers.
I want to only open B, so before open B, I have to close A.

How can I achieve this through an arcmap add-in in c#?

IApplication.NewDocument http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#/NewDocument_Method/00230000003s000000/

to create a new empty document then just open the new document

IApplication.OpenDocument http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#/OpenDocument_Method/00230000003t000000/

to teminate: IApplication.Shutdown http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#/Shutdown_Method/002300000043000000/

Terminates the application!

Never used this one myself but bumped into it a few years ago and remember thinking it would be useful.

You're adding a layer "FC" to your map which should be "FL" or "LAN". Either the feature layer or the layer should work.

Be aware that the map may be in data view instead of layout view in which case pMxDoc.PageLayout is incorrect... I can't tell what pLayout is as it's not defined in the code block.

It would be safer to use IMXDocument.FocusMap as this could be either of type layout or data view.

assuming pApp is IApplication:

IMxDocument pDoc = (IMxDocument) pApp.Document;
IMap pMap = pDoc.FocusMap;
pMap.AddLayer(LAN);

OR

(pApp.Document as IMxDocument).FocusMap.AddLayer(LAN);

I usually do it on the three lines so it's not so confusing for the reader.

oops! that was C#, my bad! The VB isn't too hard to work out from here as you're already up to the pMap = pMxDoc.FocusMap.

p.s. I personally prefer to dim my objects, it makes it easier to work out what's happening:

dim pMxDoc as IMxDocument = ctype(pApp.Document, IMxDocument)
dim pMap as IMap = pMxDoc.FocusMap

That way the reader knows for a certainty what each object is.

[GIS] Opening selected ArcMap document failed

You really are fairly stuck here. You may be able to recover your map document using the MXD Doctor tool:

MXD Doctor is a stand-alone application provided with ArcGIS: (Start>All Programs>ArcGIS>Desktop Tools>MXD Doctor) It provides functionality to analyze broken .mxd files. Depending on the analysis, entities contained in the broken .mxd file can be copied from the broken file into a new or existing .mxd file.
