Finding the width of a text
in [VB.NET]
|
From: Tor Inge Rislaa on 17 Feb 2005 15:31 Finding the width of a text I need to find the width of a text. When the user change the font in a textbox I want the textbox to fit the text automatically by changing txtMyTextBox.Width according to the actual width of the text. It can also be useful to know the actual height when using multiline textbox. Is this possible? TIRislaa

From: Jay B. Harlow [MVP - Outlook] on 17 Feb 2005 16:15 Eric & TIRislaa, Remember to be very certain to Dispose of the Graphics object that CreateGraphics return, other wise you can have a serious resource leak & your program could stop working... Dim gr As Graphics = Me.CreateGraphics() Dim sz As Size Try sz = gr.MeasureString(txtMyTextBox.Text,me.Font) Finally gr.Dispose() End Try VS.NET 2005 (aka Whidbey due out later in 2005) http://lab.msdn.microsoft.com/vs2005/ will include a Using statement to simplify the above: Dim sz As Size Using gr As Graphics = Me.CreateGraphics() sz = gr.MeasureString(txtMyTextBox.Text,me.Font) End Using Hope this helps Jay "Eric Dreksler" <ericd AT accessoneinc DOT com> wrote in message news:uGtpMETFFHA.3376(a)TK2MSFTNGP12.phx.gbl... > me.CreateGraphics.MeasureString(txtMyTextBox.Text,me.Font) > > Eric Dreksler > > "Tor Inge Rislaa" <nospam.tor.inge(a)rislaa.no> wrote in message > news:Ua7Rd.9398$IW4.224134(a)news2.e.nsc.no... >> Finding the width of a text >> >> I need to find the width of a text.

Do you then have to still dispose gr or has M'soft figured out yet how to dispose of objects with user intervention? "Jay B.
