I have written a small POP3 class that appears to work because I can return values from it using message boxes. I just need to know how to populate form controls such as text boxes. So looking at my example, how would I populate "textBox1" on "Form1" with the contents of the varible numMessages? Just trying to get my feet wet.. any assistance would be rad. Thanks CODE try { Pop3 obj = new Pop3(); int numMessages = 0; string newMess; obj.Connect("servername", "username", "password"); ArrayList list = obj.List(); foreach (Pop3Message msg in list ) { Pop3Message msg2 = obj.Retrieve(msg); numMessages = numMessages + 1; } This post has been edited by SpudNik867: 18 Mar, 2008 - 02:51 PM

Take a look at the modification I made to your code

csharp


try
    {
        Pop3 obj = new Pop3();

        int numMessages = 0;
        string newMess;

        obj.Connect("webmail.mobiledataforce.com", "nmartin", "bingogo86&");
        ArrayList list = obj.List();
        foreach (Pop3Message msg in list )
        {
            Pop3Message msg2 = obj.Retrieve(msg);
            //here we can do += 1 to increment the counter. 
            //No longer need to use something = something + 1
            numMessages += 1
            
        }
        //we will set the Text property of our TextBox to the value
        //returned from numMessages. You need to use the ToString()
        //method to convert it to text before you can display it
        textBox1.text = numMessages.ToString();

Hope that helps

So how do I manipulate form controls from like the Main() for example? Thanks for the reply QUOTE(PsychoCoder @ 18 Mar, 2008 - 03:39 PM) Take a look at the modification I made to your code csharp try { Pop3 obj = new Pop3(); int numMessages = 0; string newMess; obj.Connect("servername", "username", "password"); ArrayList list = obj.List(); foreach (Pop3Message msg in list ) { Pop3Message msg2 = obj.Retrieve(msg); //here we can do += 1 to increment the counter. //No longer need to use something = something + 1 numMessages += 1 } //we will set the Text property of our TextBox to the value //returned from numMessages.

You can access any control on your form from any method that it contains. Double check the name of your TextBox. Also, this code is in the Form's code corrent (as opposed to being in a separate class file)

So if I double click the control from the form I am taking to the code that was generated: CODE private void textBox1_TextChanged_1(object sender, EventArgs e) { } The property window shows that name as textBox1 as well??
