It can be a pain getting the right search keywords. I always put C# first as it's the most relivent keyword.

the link contains a demo which uses the FTPWebRequest class. I want to build a console application not a web application. Can anyone else tell me how to implement this functionality in a window console application usin C#

This is just an example that shows you how to use FtpWebRequest class. This class does not require the use of a Web application.

Hi all,

I'm starting my app (.NET1.1), celebrating good practice, with an info form, which contains nothing but a picturebox and a timer which closes the window after 3 sec. not more. 1000 times it works without problems but sometimes I get the following exception. How do I have to handle such exception ? I have no idea ?

System.TypeInitializationException: Der Typeninitialisierer für System.Drawing.SafeNativeMethods hat eine Ausnahme verursacht. ---> System.Threading.ThreadAbortException: Der Thread wurde abgebrochen.

Insufficient data, you might want to show the code.

Wild guess: you did use a timer other than Forms.Timer, and its handler
is performing an Illegal Cross-Thread operation on a control (probably the InfoForm itself).
If correct, the remedy is either use Forms.Timer or read up on Control.Invoke

Here is the code ... nothing spectacular

public class Info_Start : System.Windows.Forms.Form
	{
		private System.Windows.Forms.Timer timer1;
		private System.ComponentModel.IContainer components;

		public Info_Start()
		{
			//
			// Erforderlich für die Windows Form-Designerunterstützung
			//
			InitializeComponent();
			timer1.Interval = 5000;
			timer1.Start();
			this.TopMost=true;
			}

		protected override void Dispose( bool disposing )
		{
			if( disposing )
			{
				if(components != null)
				{
					components.Dispose();
				}
			}
			base.Dispose( disposing );
		}

		private void InitializeComponent()
		{
			this.components = new System.ComponentModel.Container();
			System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(Info_Start));
			this.timer1 = new System.Windows.Forms.Timer(this.components);
			// 
			// timer1
			// 
			this.timer1.Tick += new System.EventHandler(this.timer1_Tick);
			// 
			// Info_Start
			// 
			this.AutoScaleBaseSize = new System.Drawing.Size(5, 13);
			this.BackgroundImage = ((System.Drawing.Image)(resources.GetObject("$this.BackgroundImage")));
			this.ClientSize = new System.Drawing.Size(512, 360);
			this.ControlBox = false;
			this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
			this.MaximizeBox = false;
			this.MaximumSize = new System.Drawing.Size(520, 368);
			this.MinimizeBox = false;
			this.MinimumSize = new System.Drawing.Size(520, 368);
			this.Name = "Info_Start";
			this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
			this.TopMost = true;
			this.Click += new System.EventHandler(this.Info_Start_Click);
			this.Activated += new System.EventHandler(this.Info_Start_Activated);

		}
		#endregion

		private void timer1_Tick(object sender, System.EventArgs e)
		{
			this.Close();
		}


		private void Info_Start_Click(object sender, System.EventArgs e)
		{
			this.Close();
		}

	}
}

that's all ...

I agree.

Looks fine at first glance.
Now my guess is, when it fails, it is the timer firing before the form has been completely
loaded (i.e. in the middle of loading the icon, see StackTraceBack).
Remedy might be: wire a Load event and use it to start your timer.

Hi Luc,

thank you.
I'll try this.
Let's see what happens after the 999th start .... Laugh | :laugh:

Hi Frank,

you could make a test setup that creates a new form which selfdestroyes after some time,
put everything in a loop, and make the delay a random number say in the range 100...5000
msec (use a static Random !!) then let this run and watch how long it lives on average
(say 3 minutes).

Now apply my (or other) suggestions to fix, and let the same test run say ten times as
long (hence 30 minutes); if that succeeds, you know you have dramatically improved things.

The whole process would take no more than 1 hour, and need little or no human intervention.
Beats launching it manually 1000 times, and not feeling sure whatsoever... (This is
assuming you manage to make the loop fail sooner or later to begin with).

Smile | :)

Working with multiple monitors

16-Jul-07 4:51

Hi Luc,

good idea.
My feeling is that this could be a runtime problem (loading the relating lib's on the first start).
Later the lib's are in the file cache and the problem does not occur.

In parallel I will test your suggestion.

Thank's
Frank
