How to size a label taking an text and its font

[Guest]

In Win32, there is AutoSize property for a label.
How can I do the same AutoSize Task in CompactFramework ?
I don’t understand why TextBox does not have this ability either in both
WinCe and Win32, since when using a TextBox with a fixed text size, it would
be useful. Ex: a zip code field, where font can be configured and the
application have to resize the textbox to fie the zip code content.

Something like that (untested):


private void textBox1_TextChanged(object sender, System.EventArgs e)
{
SizeF size = this.CreateGraphics().MeasureString(textBox1.Text,
txtSell.Font);
textBox1.Width = (int)size.Width;
}

Windows as a platform does not use autosized entry fields. You can build
one, but the edit control is a fundamental primitive and its behaviour is
pretty much a standard. As for the label, you can create a graphics object
on the form, to which the label belongs and then use Graphics.MeasureString
to calculate the extents and resize the label

Don't you want to call Dispose on Graphics object at some point? ;-)

Yes, to call Dispose on Graphics object is a good idea. Otherwise, you'll a
memory leak.

Thank you,
