I have this simple code:
private void buttonOpen_Click(object sender, EventArgs e)
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
textBox2.Text = openFileDialog1.FileName;
}
}
When I run program form doesn't show and exit of debugging mode.
In output view writes:The program '[4244] openfiledialog.vshost.exe: Managed (v4.0.30319)' has exited with code 1073741855 (0x4000001f).
I have Visual Studio 2010 Professional.
Edit:form1.designer.cs
private void InitializeComponent()
{
this.openFileDialog1 = new System.Windows.Forms.OpenFileDialog();
this.buttonOpen = new System.Windows.Forms.Button();
this.textBox1 = new System.Windows.Forms.TextBox();
this.textBox2 = new System.Windows.Forms.TextBox();
this.SuspendLayout();
//
// openFileDialog1
//
this.openFileDialog1.FileName = "openFileDialog1";
//
// buttonOpen
//
this.buttonOpen.Location = new System.Drawing.Point(13, 48);
this.buttonOpen.Name = "buttonOpen";
this.buttonOpen.Size = new System.Drawing.Size(75, 23);
this.buttonOpen.TabIndex = 0;
this.buttonOpen.Text = "open";
this.buttonOpen.UseVisualStyleBackColor = true;
this.buttonOpen.Click += new System.EventHandler(this.buttonOpen_Click);
//

As a general rule I initialize and use my OpenFileDialog's within the event that is calling it. I can't think of a circumstance in which I would want it to be a property of my window. The first thing I would do is delete it as a property and initialize it in your event.
private void buttonOpen_Click(object sender, EventArgs e)
{
using (OpenFileDialog openFileDialog1 = new OpenFileDialog())
{
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
textBox2.Text = openFileDialog1.FileName;
}
}
}
You don't need to set the FileName property to anything because the dialog will do it for you.
The only thing I found on your error code was this (Program and debugger quit without indication of problem). Which in your current code I cannot find anything that would cause this. If you are accessing unmanaged code you may need to enable unmanaged code debugging.
