Hi,

I get the same error, the name 'objXXXXXX' does not exist in the current context in the code I've pasted below.
I've searched the net but found no good solutions to this but I can say this about the code.
Yes I copied it from a different project and Yes I've written it from scratch, it stops at the same time over and over.


I'd be really happy to get some help with this code =)
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
 
namespace asdasdasdasdasdasd
{
    public partial class Form1 : Form
    {
        GroupwareTypeLibrary.Application5 objGWSession = new GroupwareTypeLibrary.Application5();
        GroupwareTypeLibrary.Account objAccount = null;
 
 
        public Form1()
        {
            InitializeComponent();
        }
 
        private void button1_Click(object sender, EventArgs e)
        {
            //Using Multilogin
            string sUserName = textBox3.Text;
            string sTrustedAppKey = textBox2.Text;
            string sTrustedAppName = textBox1.Text;
            string sCmdLine = "/*ipa*-127.0.0.1 /ipp-1677";
            string sWhenToPromp = "egwPromptNever";
            string sPassword = textBox4.Text;
            string sReserved = null;
            string sMessageClassName = "GW.MESSAGE.APPOINTMENT";
            string sMessageType = "egwDraft";
 
            objGWSession.SetTrustedApplicationCredentials(sTrustedAppName, sTrustedAppKey);
            objAccount = objGWSession.MultiLogin(sUserName, sCmdLine, sPassword, sWhenToPromp, sReserved);
 
            // From here the errors start saying each of the obj's( except objAccount ) does not exist in the current context.
            objMailBox = objAccount.MailBox;
            objMessages = objMailBox.Messages;
            objAppointment = objMessages.Add(sMessageType);
 
            objAppointment.Recipients.Add();
        }
    }
}

You have objGWSession  & objAccount declared here:
GroupwareTypeLibrary.Application5 objGWSession = new GroupwareTypeLibrary.Application5();
        GroupwareTypeLibrary.Account objAccount = null;

but you have not declared these: objMailBox , objMessages,   objAppointment

how do I declare them? They are subtypes of the account.
It will in the end be this thing but used in the different declarations to propagate to it : GroupWareTypeLibrary.Account.MailBox.Messages.Add(sMessageType) through objMailBox, objMessages, objAppointments

Then objMailBox should be of type objAccount.MailBox,
objMessages should be of type objMailBox.Messages

If you can share what your Account Class looks like we can get better idea.

For objMailBox try this:
GroupwareTypeLibrary.Folder objMailBox = objAccount.MailBox;

If that get rids of objMailBox error ...then you have to similarly get return type of other properties like
Messages etc....

If you have any doubt...you will have to post info about Messages

I am stuck a bit further down now, I have written a bit more to the code and I get an error about not having set Object reference to an instance of an object.

The error occurs on line 44, GroupwareTypeLibrary.Folder objMailBox = objAccount.MailBox;

Code below
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
 
namespace asdasdasdasdasdasd

        }
 
        private void button1_Click(object sender, EventArgs e)
        {
            GroupwareTypeLibrary.Application5 objGWSession = new GroupwareTypeLibrary.Application5();

Because you don't have  objAccount  set. You are setting it initially null then this line is commented out...

//objAccount = objGWSession.MultiLogin(sUserName, sCmdLine, sPassword, sWhenToPromp, sReserved);

So before accessing objAccount.MailBox ... objAccount should not be null...

bah, a typo :P

I uncommented it and now have an error on objApppointment2.startdate = dt; where it tells me that its not apart of an instance, use the "new" keyword to create an object instance.

I think its because I use an entirely different part of the COM object and that I dont hook it to the instance where I created the message draft as an appointment.

Any clue how I can tie this to it? ;-)


Also, I've got further now then I've ever been, this means a ton to me :)
