Arcmap: attach python script to a button?

Question

In ArcMap 9.x how can I attach a python script to a button?

Answer 1

This works in VBA to run a Python script. Just call the subroutine with a button.

Private Sub python_Click()
    Shell "C:\Python25\python.exe ""C:\rowcount.py"
End Sub

Hope this helps.

Answer 2

As @fmark says, the easiest way to integrate a Python script into ArcMap is through a toolbox, which I'd recommend.

That said, if you really need to (eg, you need a nicer front end than the toolbox) you have two options:

1. You can call the script as a command line argument from another program that is linked to the button - the easiest would be VBA.
2. You can add the Python script to the toolbox, and call the custom toolbox from your button (VBA, VB.Net, C#.Net).

Still, I'd go with @fmark and just add the script to the toolbox given the choice.

Answer 3

The way to do it in C# would be like this using the ArcGIS template for a button.

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Diagnostics;

namespace RunEditPython
   {    
    public class PythonEdited : ESRI.ArcGIS.Desktop.AddIns.Button
    {

    public PythonEdited()
    {
    }

    protected override void OnClick()
    {
        System.Diagnostics.Process.Start("C:\\temp\\WHP\\WellsEdited.py");
    }
    protected override void OnUpdate()
    {
        Enabled = ArcMap.Application != null;
    }
}

}
