Toolstrip Exception - bad .NET?

M

Mike

I have a program that is crashing on some machines (at a client of
ours). I have determined that it goes down on this line of code:

ToolStrip x = new ToolStrip();

I created a simple test app that only performs this one line of code.
It throws an exception so I know the problem is not caused by
something in my code. It seems like there is a problem with .NET. We
have tried uninstalling and reinstalling .NET 2, but it doesn't help.

Please, please, please, does anybody have any ideas? The following is
the exception info from my test app...

"Parameter is not valid"

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Well, it looks like this is happening within a button click, which
suggests that it performs more than that one line of code.

Could you post a short but complete program demonstrating the problem?
See http://pobox.com/~skeet/csharp/complete.html for more details.

Thanks for the quick response. You are correct. What I created was a
form application with a single button. The handler for the button
click only does the one line of code.

Since the time when I retrieved these exception details, I changed the
app to make it simpler so I don't have that exact code. The new test
app runs the bad line of code in the constructor within a try...catch
and shows a message on the form based on the results. I get
"succeeded" on my system, but "failed" on the client's system. Here is
the new code...

[Form1.cs]
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace WindowsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
try
{
ToolStrip x = new ToolStrip();
}
catch (Exception)
{
lblResults.Text = "FAILED";
return;
}
lblResults.Text = "SUCCEEDED";
}
}
}

[Form1.Designer.cs]
namespace WindowsApplication2
{
partial class Form1
{
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.IContainer components = null;

/// <summary>
/// Clean up any resources being used.
/// </summary>
/// <param name="disposing">true if managed resources should be
disposed; otherwise, false.</param>
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

#region Windows Form Designer generated code

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.lblResults = new System.Windows.Forms.Label();
this.SuspendLayout();
//
// lblResults
//
this.lblResults.Font = new System.Drawing.Font("Microsoft Sans
Serif", 14.25F, System.Drawing.FontStyle.Bold,
System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.lblResults.Location = new System.Drawing.Point(12, 56);
this.lblResults.Name = "lblResults";
this.lblResults.Size = new System.Drawing.Size(200, 32);
this.lblResults.TabIndex = 0;
this.lblResults.Text = "[results]";
this.lblResults.TextAlign =
System.Drawing.ContentAlignment.MiddleCenter;
//
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(224, 144);
this.Controls.Add(this.lblResults);
this.FormBorderStyle =
System.Windows.Forms.FormBorderStyle.FixedDialog;
this.MaximizeBox = false;
this.Name = "Form1";
this.Text = "Framework Tester";
this.ResumeLayout(false);

}

That code will always fail - it doesn't run the InitializeComponent
code in the designer file.

However, I wonder whether your client's machine doesn't have the
appropriate font installed. On my box it's using "Segoe UI" as the font
name - you might want to check whether that's installed on your
client's machine.

Thanks for the reply. I'll check the font.

BTW, I'm a little confused by your comment that this code will never
work. It works on my machine. That code is straight from what dev
studio gives me when I create a new windows app project.

No, it's not. Check the constructor. You got rid of the call to
InitializeComponent - indeed, it will throw a NullReferenceException
because lblResults is still null.

My mistake. I thought you meant that the designer can't have the
InitializeComponent function.

The call is in my test app. I made a mistake when I copied the code
that caused it to be omitted. The correct constructor follows...

public Form1()
{
InitializeComponent();

try
{
ToolStrip x = new ToolStrip();
}
catch (Exception)
{
lblResults.Text = "FAILED";
return;
}
lblResults.Text = "SUCCEEDED";
}

Thanks Jon! I just heard back from our client that the font was the
problem. Windows thought the font was installed because it was in the
registry but it really was not there. Deleting the registry key
allowed the font to reinstall and everything is OK now.
