Hi When I open the form I get error Timed out while connecting to named pipe. What it mean and how to fix ? Thanks

Just a gut instinct but do you have any code in your form's constructor besides a call to InitializeComponent? The constructor (ctor) of your form is called by the designer. If your ctor attempts to load anything that is normally not accessible at design time (such as databases) then it'll fail. Anything beyond initialization of UX fields should be postponeded until the OnLoad method is called. Click the Show Call Stack link and look at what is being called.

I can not see the form any more

Does it happen in case of any new Forms project, even after restarting the computer?

Hi @William de , Welcome to Microsoft Q&A,

Judging by your statement, your mistake only appears in this project, so can you tell us a step that can be reproduced? How do you add a new form to the project?

I just now compared the code generated for a new form and the form that does not want to load and I found few lines are different. I dont understand what those lines for but once I copied the code generated for form2 into form1 I was able to open form1

I really dont know what caused that change

namespace myapp { 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.components = new System.ComponentModel.Container(); this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font; this.ClientSize = new System.Drawing.Size(800, 450); this.Text = "Form1"; } #endregion } }

That is the auto-generated code that the designer writes to as you build your form visually. Behind the scenes the designer is generating code in the .designer.cs file that you should never touch. Ultimately all the stuff you do in the designer ends up being generated C# code in this file.

Do not leave this file open in the editor, don't touch it directly unless the form won't load and ensure that it is part of your source control system. If you lose this file then all your designer changes (including any controls you add) are gone.
