Exception

[PiotrKolodziej]

Hi.
I have hugie problem with exception. I need to debug button1_Click code,
after openfiledialog is called but i can't because of this:
System.Threading.ThreadStateException was unhandled
Message="Current thread must be set to single thread apartment (STA) mode
before OLE calls can be made. Ensure that your Main function has
STAThreadAttribute marked on it. This exception is only raised if a debugger
is attached to the process."


Here is few samples of my code:

namespace IRDAcontrol
{
public partial class Form2 : Form
{
public string Button = null;

public Form2()
{
InitializeComponent();

comboBox1.Items.Add("Volume UP");
comboBox1.Items.Add("Volume DN");
comboBox1.Items.Add("Mute");
comboBox1.Items.Add("<Custom>");

}

private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show(Button + " " + openFileDialog1.FileName);

IRDAcontrol.configFile.setParameter(Button,
openFileDialog1.FileName);
this.Dispose();
}

private void button2_Click(object sender, EventArgs e)
{
DialogResult asd = openFileDialog1.ShowDialog();
}
}
}



AND this is main:


using System;
using System.Collections.Generic;
using System.Windows.Forms;

namespace IRDAcontrol
{
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}


For any help thanks.

You've shown Form2, but Form1 is what's being started in Main. Is Form2
being run in a different thread, perhaps?
