Popup Outlook contact makes the WinForm stuck and hold

[manfree]

Hi all

I would like to popup an Outlook contact via a Click button. The "Popup action" works fine~
However, after the outlook contact comes up, the WinForm(Form1) seem stuck and hold ....
I can't move, minimize and maximize the WinForm ?????
Any body know what is the problem in here ??
Thanks

using Outlook = Microsoft.Office.Interop.Outlook;

    public partial class Form1 : Form
    {
        Outlook.Application oApp = new Outlook.Application();
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }
        private void FindContactEmailByName(string firstName, string lastName)
        {
            Outlook.NameSpace outlookNameSpace = oApp.GetNamespace("MAPI");
            Outlook.MAPIFolder contactsFolder = outlookNameSpace.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderContacts);

            Outlook.Items contactItems = contactsFolder.Items;

            try
            {
                Outlook.ContactItem contact = (Outlook.ContactItem)contactItems.Find(String.Format("[FirstName]='{0}' and " + "[LastName]='{1}'", firstName, lastName));
                if (contact != null)
                {
                    contact.Display(true);
                }
                else
                {
                    MessageBox.Show("The contact information was not found.");
                }
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            FindContactEmailByName("Tom", "Lee");
        }

    }
}

Hmmm. This is strange as your code works fine on my machine
I''m using Vista home and outlook 2003
There are two things coming in my mind. One is virus checking
When I start your program since you open Outlook when form1 is created my Avast antivirus just shows up on the screen for a second. Maybe your virus scanner makes troubles ?
The other thing is that you are not closing outlook and it still sometimes remains in the task manager after closing the program. So I added

privatevoid Form1_FormClosed(object sender, FormClosedEventArgs e) {
   try {
        oApp.Quit();
        oApp = null;
         } catch (Exception ex) {
           MessageBox.Show(ex.Message); 
   }
}

This seems to close outlook in the taskmanager too.

One more thing that comes to my mind is that Outlook has this function when ever an external program tries to access outlook, outlook shows a prompt, maybe you are stuck with that.

Yep this was my problem with outlook in XP and was why I never again used it with my programs, but this seems not to be the way when I do his code in a Vista enviroment, maybe because the whole security system has changed ?
