How to create delete command in vb.net?

[Ajay Bhalala]

I have one application in which I used one richtextbox and some buttons.

I have 1 button named "Delete".

I want to create delete command using the code.

When the user clicked the "Delete" button after the entering and selecting the text in richtextbox then the selected text should be deleted.
How can I do this?

Well, first you need to be able to detect what is selected in the textbox. The RichTextBox control has a Selection Property that can probably help you with this.

Once you have the selected data you need to remove it from the text that the textbox is displaying in the click event for the delete button.

I have written the code as follows...

Dim a As Object
a = RichTextBox1.SelectionFont
a.remove()

There is no error, but runtime error is occured
Runtime Error : "Public member 'remove' on type 'Font' not found."

There is no remove or delete property available for the selection font.

What can I do about this?

[Frinavale]

I have never used the RichTextbox control before.

I couldn't find anything about the SelectionFont property when I was looking at the documentation for the class.

I don't know what that is but you aren't using the right property....

which property should I use?

[Frinavale]

I think you should probably be using the Selection Property.

That property will return a TextSelection object that will contain information about what is selected.

You can use the TextSelection.T ext Property to retrieve what is selected and then use String methods to remove the text that you want to remove. (Like the IndexOf method used with the Remove method)
