Hallo Daniel_g!
Öffentliche Events, bei denen sich eine andere Form einklinken kann, können dazu benutzt werden. Die Events transpoertieren die benötigten Daten einfach mit, wenn sie gefeuert werden.

hi, der Marcel!
Wenn du mir sagen könntest was mache ich verkehrt...
using System;
using System.Windows.Forms;
using System.Drawing;
public class MyForm : Form
{
private Button btAction = new Button();
private String [] text = {"1111111111111",
"2222222222222",
"3333333333333",
"4444444444444",
"5555555555555"};
public int index = 0;
public delegate void OnSetText(string str);
public event OnSetText doSetText;
public MyForm()
{
this.Text = "My simple Form in UltraEdit";
this.btAction.Location = new Point(0, 0);
this.btAction.Text = "Action";
this.btAction.Click += new EventHandler(this.Action);
this.Controls.Add(this.btAction);
}
private void Action(object source, EventArgs e)
{
if(this.index > 4) this.index = 0;
if (doSetText != null)
doSetText(this.text[index]);
index ++;
}
}
public class MyForm2 : Form
{
private TextBox txtText = new TextBox();
public MyForm2()
{
this.Text = "My simple Form in UltraEdit";
this.txtText.Location = new Point(0, 0);
this.txtText.Size = new Size(200, 25);
this.Controls.Add(this.txtText);
}
public void setUserName(string str)
{
this.txtText.Text = str;
}
}
class MainApp
{
public static void Main()
{
MyForm2 f2 = new MyForm2();
MyForm f = new MyForm();
f.doSetText += new f.OnSetText(f2.setUserName); //<---Fehler!
Application.Run(f);
}
}
Fehler:
2FormsMitEvents.cs(68,22): error CS0246: The type or namespace name 'f' could not be found (are you missing a using directive or an assembly reference?)
