Simple Form Example

[62BJW]

Can anyone point me to a very basic/simple example of how to use a windows form? I'm assuming that I call the form from my main execute and place the code that performs a task in the button_click event of the form? Sounds simple enough but I'm having problems. I've done this years ago in VB but I'm still a rookie when it comes to C#. Getting there slowly but surely.

Thanks

Dear Bernie,

Thank you for your query.

Here is one that I am especially fond of, since it creates the .NET Windows form programmatically from scratch on the fly, making it easier (possible at all) to see and understand every single step that is going on:

It does not handle any click events, though, because all the user can do with it is look at it and then close it.

Here is a completely different WPF sample that might help better understand how to handle click events:

I hope this helps.

Best regards,

Here is a simple example using the Macro Editor with C#. 

It should be farily easy to convert to an Add-in by adding the typical code an Add-in starts with (the execute method and such). 

You do need to add references to Windows.System.Forms, and System.Drawing.

I'm sure its not the most elegant example of programming, but it will give you the basic idea.

If you need a particular variable to be available both within and outside your form, you have two options, and they are both included here. 

1 - You can declare a public static variable like "myreturn", "mystring", or even the "textbox1", or

2 - You can pass the variable to the form like the "acomment" and "anothercomment".

Hope this helps.

@stever66 This is also a helpful line to add (by CancelButton): 

this.AcceptButton = button1;
