Hi All,

I am experiencing difficulty in displaying a symbol "►" in a control:

I cannot get the arrow to display correctly when the string is printed to the screen.

I have tried:

legendWindow1.Add(count.ToString() + "\u25C4");

and

legendWindow1.Add(count.ToString() +  "►"\);

both of which just produce a square apposed to the symbol. I have followed the string through the add method and it is entering that incorrectly so its something in this line that i cant work out.

Thanks in advance George

Solution 1

Set control's font to any unicode font available, like "Arial Unicode MS"

I tried this and still could not get the arrows to show, although i did use an arrow from areal font.

It should do. Make sure you set the font on the control you're trying to put this symbol into, and the font you're choosing contains the character.

I suspect that it is entering Add fine but your IDE is using a font which can't display it so you get a square in the debugger.

Solution 2

"16" Solid Forward Arrow. "16" is the exented ascii code for the symbol that you want. You can use it

C#

Convert.ToChar(16)

This will give you that symbol. But of course your page must be support extended ascii format

I could not access the link due to work filtering and had a go but think i must have missed something as couldn't get this working.

I found a solution but its not ideal

<pre> protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);

Graphics g = e.Graphics;
GraphicsPath gp = new GraphicsPath();

// Font for the form is set to areal
gp.AddString("►", Font.FontFamily, (int)Font.Style, (int)(Font.SizeInPoints * 1.33333333), new Rectangle( 10,10,100,100), StringFormat.GenericTypographic);
g.FillPath(Brushes.Red, gp);
}</pre>

Overriding the paint of a normal form and drawing the string from a graphics path will work, but there probably is an easier way
