I have made a Simple Program, which edits Text Documents. It uses A class library call Text.dll.

After I publish my Application, And open the published folder there're 2 file, One is TextEditor.exe and the other one is Text.dll. (Text.dll is used to write/read txt files)

When I delete the Text.dll, run the application and try to save a text file. But It gives me a system Error from .Net FrameWork. How Can I Convert That to a message of mine ?

It's about ASP.NET, but I'm talking about windows forms applications !

I think it will be exception.
use try catch block, and in catch block print message at label or in messagebox

You should either use try-catch blocks or check the existance of file at the starting point. You can find the use of try-catch block on google or MSDN site so i will not explain it here.

Use of file checking should do:

1) Open Project

2) in the event code write

C#

if (File.Exists(filePath)){
    Application.Run(new StartForm);
}
else
{
    MessageBox.Show("File not found");
}

That should work out for you.
or you can do the same with try catch block.
