Hello everybody.

I have created an addin that should be activated by a push of a button on the data card. This addin writes values in variable fields.

Therefore I use the function "poCmdMgr.AddHook (EdmCmdType.EdmCmd_CardButton);"


In debug mode everything is going well if I have a file selected but if I do start a search, I get the following error message "0x080004003 - an invalid pointer was supplied to the method"


Here the code I have created


using System;
using Microsoft.VisualBasic;
using EdmLib;
using System.Runtime.InteropServices;

namespace CardButtonControl
    public class CardButton : IEdmAddIn5
        public void GetAddInInfo(ref EdmAddInInfo poInfo, IEdmVault5 poVault, IEdmCmdMgr5 poCmdMgr)

What am I doing wrong??

Any help would bo great!
