    Label Font Size

    Is there a way to / or a mathematical formula to see if a font size is 'too
    big' for a label.

    I have a label that is docked to 'fill' a form, and I want to resize that
    font based on the width and height of the label.

    So far I have something like this on the Form_Resize event:
    Label2.Font = New Font(Label2.Fon t.Name, _
    Label2.Size.Hei ght - 100, Label2.Font.Sty le)

    but it only works to a point, once the height gets past a certain point, the
    font is simply too big for the label.
    I know I can add some math for a maximum font size compared to the height
    and width of the label, but im wondering if there is another simpler way of
    a mathematical formula to do this in one shot.

    Thanks,

    miro

      I'm not sure but you may want to enable Label's "AutoSize" property to
      True because if you keep it disabled, the label borders will remain
      fixed regardless of label's font. By the way, based on your
      description, it's clueless that why you're using the code while
      resisizng form.

          You want to be looking at the font's height to size ratio (which is fixed,
          but varies from font to font)
          In pseudocode you need to do this
          Ratio = font.height/font.size
          New font size= label.height/Ratio

          If you need to adjust the width to the content (or the content to the width)
          use TextRenderer.Me asureText with the font from the label.

          Good luck

              Re: Label Font Size

              Yeah I have started looking at finding the ratio,

              Another thought I had is to do some benchmarks in some if statements - that
              might be easier if i cannot find the ratio easily.

              Thanks for your help...
              Ill be playing with this this weekend.

                  Re: Label Font Size

                  Autosize sizes the labels borders to the font size

                  I am trying to size the fontsize to the labels borders.

                  I dont see how it is clueluess...as I am trying to enlarge and shrink a
                  label on the screen depending on the realistate.

                      Re: Label Font Size - Solved

                      I have found a very simple solution to my problem - just posting it so if
                      anyone else wants to try this, they can.

                      It's based off of what Clive Lumb said.

                      I temporarily put 3 textboxes on the screen. On resize i just put the form
                      width and height and fontsize there so i can watch the size setting.
                      Basically I found ( with my window layout ) font size 232 was teh biggest
                      font size i wanted.

                      Then I took the font size on an inbetween window size - and divided it by
                      the form height and got a 66% font size to height ratio
                      then I took the font size and divided it by the width and got a 22% font
                      size to width ratio.

                      In the end...I take the height and multiply it by 66%
                      take the height and multiply it by the 21%
                      take the minimum of the two

                      works like a charm.

                      Thanks Clive - you got me on the right track.

                      the textbox's will be removed but I left them there so you get the idea.
                      ===
                      TextBox1.Text = Me.Size.Width.T oString
                      TextBox2.Text = Me.Size.Height. ToString

                      Dim CalcFontSizeA As Integer = Math.Min(232,
                      CType(Math.Roun d(Me.Label2.Hei ght * 0.66, 0), Integer))
                      Dim CalcFontSizeB As Integer = Math.Min(232,
                      CType(Math.Roun d(Me.Label2.Wid th * 0.21, 0), Integer))

                      Dim FinalFontSize As Integer = Math.Min(CalcFo ntSizeA,
                      CalcFontSizeB)


                      Label2.Font = New Font(Label2.Fon t.Name, FinalFontSize,
                      Label2.Font.Sty le) )

                      TextBox3.Text = Label2.Font.Siz e.ToString
                      ===

                      Thank you,

                      Cheers'

                          You need to look towards System.Drawing. Graphics.Measur eString.

                          This method should give you the length of the string as it will be
                          drawn on the form. It accepts a Font argument so as to better
                          pinpoint the exact size. I've worked with it before and its not
                          perfect, but pretty decent.
