Hi,

Is it possible to use the likes of superscript and subscript in labels
(for example, so that I could have x2 and have the 2 in superscript) or
mix character sets in a label (eg have Ex read sigma x)?

I've looked and can't find anything useful....

Thanks

Paul

Hi,

I don't know where the problem lies with this one as I'm seeing the same
behaviour with mono and under VS 2010 on Linux and Windows platforms.

I have a simple winform which has in it a NumericUpDown, two group boxes
and two buttons. The code then dynamically inserts a number of NumberBox
objects into one group box and a pile of labels into the other.

(A numberbox is just an overloaded TextBox - details are at
http://www.all-the-johnsons.co.uk/csharp/numberbox.html)

If I click the NumericUpDown, the code inserts new boxes and also
reduces it as expected. However, if I click once to create 3 boxes and
then go back down to 2, half of the third row still remains and I have
no idea why!

NumericUpDown goes from 3 to 6, no decimals

[code]
private void numericUpDown1_ValueChanged(object sender, EventArgs e)
        {
            drawBoxes((int)numericUpDown1.Value);
        }

        private void drawBoxes(int number)
        {
            int ar = number;
            int b = ar;
            int p = 0; // position
            int r = 0; // current row
            ar = Convert.ToInt32(Math.Pow(ar, 2));
            NumberBox[] tmp = new NumberBox[ar];
            Label[] lbl = new Label[ar];
            int t = 0;
	    int m = 65;
            for (int n = 0; n < ar; ++n)
            {
		m += n;
                tmp[n] = new NumberBox();
                tmp[n].Location = new System.Drawing.Point(7 + p, 20 +
(26 * r));
                tmp[n].Name = "numberBox" + n.ToString();
                tmp[n].Size = new System.Drawing.Size(42, 20);
                tmp[n].TabIndex = n;
                groupBox1.Controls.Add(tmp[n]);

                lbl[n] = new Label();
                lbl[n].Location = new System.Drawing.Point(7 + p, 20 +
(26 * r));
                lbl[n].Name = "label" + m.ToString();
                lbl[n].Text = "0";
                lbl[n].Size = new System.Drawing.Size(42, 20);
                lbl[n].TabIndex = m;
                groupBox2.Controls.Add(lbl[n]);

                p += 48;
                if (t + 1 != b)
                    t++;
                else
                {
                    t = 0;
                    r++;
                    p = 0;
                }
            }
            int z = 8 + b * 48;
            int y = 8 + (b * 26) + 16;
            groupBox1.Size = new System.Drawing.Size(z, y);
            groupBox2.Location = new System.Drawing.Point(32 + b * 48,
43);
            groupBox2.Size = new System.Drawing.Size(z, y);
            this.clear.Location = new System.Drawing.Point(16, y + 48);
            this.calc.Location = new System.Drawing.Point(97, y + 48);
            ClientSize = new System.Drawing.Size(z * 2 + 32, y + 80);
            nbArray = tmp; // global variable
            rdArray = lbl; // global variable
        }

I've gone through the code with the debugger, but can't spot anything
out of the ordindary. I've also tried adding an Invalidate() at the end
of the method, but still it gives the half box.

Any help here would be appreciated

Thanks

Paul

Your code does not seem to remove controls. I see how you
create and add them to some container, but you never
remove them.

Ah! I thought that as I dynamically create them, they'd just be removed
(if I go from say 6 rows to 5 rows, row 6 is completely removed).

How do I go about removing them? Ideally, I'd remove all then add the
new ones in.

Thanks

Paul

There's no 'rich' text in buttons IIRC.  However there are Unicode
characters that should help though, e.g. U+00B2 is Superscript 2, ditto 3,
and 1 is U+00B9
http://www.fileformat.info/info/unicode/block/latin_supplement/list.htm
That's dependent on font support of course...

Hi,

This is a bug in Mono.

It comes from this file:
https://github.com/mono/mono/blob/master/mcs/class/Managed.Windows.Forms/System.Windows.Forms/X11Dnd.cs

Every DragEventArgs object intialized in this class pass 0 as the keystate
value.

Not sure how to fix this right now, but anyone can pick this up.
