trouble building a custom control in Windows Forms Control L

John Galt

I am engaged in self taught C# programming, using a book titled "Learn Visual C#". One of the book examples is giving me problems that two days of research have proven to be unhelpful.

In a nutshell, the project yields Visual Studio supplied default code does not reflect renaming UserControl1.cs, and building the code does not result in a .dll file in repos\bin\release.

Here are the steps as given in the book:

1) In New Project window, choose Visual C#, Windows, Desktop.

2) Select Windows Forms Control Library, and name the project NumericTextBox.

3) Rename the default file UserControl1.cs to be named NumericTextBox.cs.

4) Show all files and delete NumericTextBox.Designer.cs.

5) Opening the code window should reveal: namespace NumericTextBox -- etc, but it reveals namespaceUserControl1 -- etc.

6) Add text box properties for backcolor ,forecolor, and font. This works, but I have not yet figured out how to post code properly in this forum.

7) Save the project, click build NumericTextBox. -- This is where the .dll file should be found in bin\release. -- but it is nowhere to be found

Please provide me with insight to make these instructions work.

Thanks in advance for your replies.

SOLVED

I found the solution! After creating the solution one step at a time according to the book instructions and starting over to do it again numerous times, I found that two steps caused compiler errors:
deleting the *.Designer.cs file in Solution Explorer
commenting out InitializeComponent() in the code window
Now the .dll file is available, and the control is programmable.

Thanks for all the replies.

Amit, let me ask again. How do you want the code ... screenshot? ... notepad? .. notepad++?
Would you prefer having the code commented to indicate my problems or have the problems listed in the body of the post?

to all who are following this thread ...

This is a very small project intended to be used later in another project. I will take the time to build the project from scratch to allow me to share code and/or screenshots of the steps where there are problems in following book instructions.

Shweta,

My apology ... I am new to the forum. I had not noticed that uploads must be zipped. That is where my problem came from.

Hi john galt,
You can manually go ahead and rename namespace to NumericTextBox, from UserControl1. This can be done by selecting UserControl1 and select rename option.

If it is build successfully, then .dll must be generated either in your Debug folder or in Release folder. This depends on what configuration ahve you choosen.
