Drawing textbox

[MA Awan]

I want to draw a textbox at runtime using mouse. I know I hav to use MouseUp,MouseDown and MouseMove events to do this. But i cant find the way to set textbox's height and width. Can u plz help?

A TextBox is a Windows Forms control. This site has a Windows Forms forum. Please post in the most appropriate forum for the topic. Moved.

You can set the Width property of a TextBox any time but you can't set the Height of a TextBox unless the Multiline property is set to True. You can either set the Height and Width properties individually or you can set the Size property.

[ame="http://www.vbforums.com/showthread.php?t=426684"]This[/ame] shows you how to draw a line that is bounded by a rectangle defined by two points. You can use the same logic but just use that Rectangle to set the Bounds property of your TextBox.

thnx alot. I hav been able to draw it. Now i want to embed this textbox into richtextbox. i hav used rtb.controls.add method to add it. But i want to disable the area of rtb which is under this textbox so that user cant write in this area.

I doubt that that's possible. It would certainly require unmanaged, i.e. non-.NET, code if it is.

OK. Can u plz tell one more thing. I hav added some code in KeyPress event of rtb. If i add textbox into this rtb, can i somehow use the same code for textbox?

To attach a method to an event at run time you use the AddHandler statement, e.g.

AddHandler someObject.SomeEvent, AddressOf SomeMethod

If you need to refer to the actual control that raised the event within the event handler you use the 'sender' parameter.
