How do I save a .mxd programatically? The project is never saved and on button-click, I want to save the project.

I use SaveFileDialog to get the filepath and then use the following:

IMapDocument mapDocument= ArcMap.Document as IMapDocument;

This crashes my ArcMap. Any suggestions?

  • Any error message or log file?

  • Can you confirm what the variable projectpath is?

I was able to achieve results as following:

public void SaveProject()
    UID uid = new UIDClass();
    //uid.Value = "{119591DB-0255-11D2-8D20-080009EE4E51}"; 
    uid.Value = "esriArcMapUI.MxFileMenuItem";
    uid.SubType = 3;
    ICommandItem item = ArcMap.Application.Document.CommandBars.Find(uid, false);

Appreciate your help.


you sure obtain IApplication/IMxApplication hook somehow in your code then you can obtain IMxDocument pointer and then cast it to IMapDocument:

IMxDocument ipMxDoc=(IMxApplication)ipApp;

//Suppose ipApp has been obtained via hook passed in OnCreate method of ICommand interface

IMapDocument ipMapDoc=(IMapDocument)ipMxDoc;

//Suppose fileName obtained from a SaveDialogBox
