ASCII Characters in VB

[Klogg]

How do I display ASCII characters as the text property of a button?

[techmanbd]

me.button1.text = chr(ASCII CODE NUMBER)

[Klogg]

If I do that, it says, "Method System.Char.Chr not found." If I compile the program when it says that, an "a" with a tilde over it appears as the button text, but I told it to display the Greek letter pi. Edited October 23, 2003 by Klogg

Button1.Text = Convert.ToChar(code number)

[Klogg]

I tried that too, and it does the same thing. I also found out that if I put in a different code number, it displays a different character, but it's not the one it's supposed to be either. Why is it displaying this error message and showing the wrong characters?

[Volte]

That depends...what ASCII code are you attempting to display?

[Klogg]

Pi, but it does the same thing for every one that I try.

[Volte]

What happens when you try 97?

[Klogg]

The error message still appears, and the character in the button is "a."

[Klogg]

Looks like it shows the right characters until I get up to 128.

[Volte]

Many of the characters above 128 are not all the same in every font. Make sure you're looking at the ASCII table for the right font. I recommend the Character Map for that.

[Klogg]

What is the character map?

[Volte]

It comes with Windows.

 

Start -> Run -> charmap.exe

[Klogg]

Ok, thanks.

[Klogg]

One more question. Is there either a way to find the ASCII value from the Character Map or a way to convert Unicode to text in VB? If I just copy and paste the pi symbol to my code, it changes it to "p" every time I close Visual Studio and open it again.

[Volte]

What do you mean by that? Can't you use Convert.ToChar?

[Klogg]

I'm assuming that the "U+03C0" that the character map gives me is Unicode, so how do I tell that to VB or find an ASCII value for it? If you can put that value in the Convert.ToChar statement, I can't figure out how.

[Klogg]

I found out that the "U+03C0" is the Unicode, or maybe just the number part of it. Could someone please tell me how to convert this to an ASCII value or how to tell VB to display it?

[Klogg]

Never mind. I figured it out. I have to convert the 03C0, which is hexidecimal, to decimal, and enter that in a Convert.ToChar statement. It works, but it still says, "Method System.Char.ToChar not found," in the Task List for some strange reason.
