I'm creating a program the must show the time (a clock) in a user control
and the text must fill the user control. How do I make text dynamically
resize to fill a label/panel/usercontrol? Thanks!!

Thanks for the reply. I ment the actual size of the text within the
control. I suppose from your statement there isn't a "fill" for a font
size, that I'll have to play around with the sizes. That's the (sort of)
obvious way, I was looking for something quicker. Do you at least know if
there are classes (and if so, which ones) to determain the actual physical
size of some text?

Thanks,

Noah,

Give this a shot. Just set the size of the label to the size of the form in
the forms resize event. Used it for a similar problem. I think it's based
on some samples from Petzold's Programming MS Windows with C#

Enjoy,

if( this.Text == "" )

Console.WriteLine( "null string in paint" );
return;

path = new GraphicsPath();

path.AddString( "Ty", this.Font.FontFamily, (int)
this.Font.Style, 100,
new Point( 0, 0 ), new
StringFormat() );

rectfTemp = path.GetBounds();

path = new GraphicsPath();
path.AddString( this.Text, this.Font.FontFamily, (int)
this.Font.Style, 100,

rectfBounds = path.GetBounds();
rectfBounds.Height = rectfTemp.Height;

PointF[] aptfDest = { new PointF( 0, 0 ),
new PointF( this.Width, 0 ),
new PointF( 0,
this.Height ) };

e.Graphics.Transform = new Matrix( rectfBounds, aptfDest );
e.Graphics.SetClip( path );
e.Graphics.FillPath( new SolidBrush( this.ForeColor ), path );
}
}
