How to insert mathematical symbols (like square root, volume at angles etc) in delphi text fields (label, memo etc)

Some of them you can get to by using Ascii character codes. For example, CHR(251) is the "Square Root" character: ?. You can add this to your text by holding down the Alt key and typing 251 on the number pad. You may be able to get other characters by using the MS "Character Map" application (in XP, found under Start|Accessories|System Tools) to copy and past the characters you want.

which charset you are using?

i tried all charsets, but didnt found square root, and for some symbol were black cell, maybe i dont have right font? Where can i get one if the problem there..

Hmmm... this is interesting - the square-root character showed up in the edit window when I was typing, but came out as "?" in the response that actually displayed above. In the Character Map application, I can find it in the Times New Roman font, toward the bottom, along with a number of other math symbols.

the process that translate the posting to the page doesn't recognize ASCII characters, they all come in as '?'.

Regany, when you are setting the caption or label text, do it in the program:

TextBox1.Caption := 'Something ' + CHR(251)

and the correct character should show up in the control.

ok, i done that, and as the answer appears "something ?".... Leslie which charset you used? Because i tried all of them, but none was correct.

P.S. instead of ? there is letter form my language alphabet

i'm not choosing a char set, it's the ASCII code for it no matter what the font or character set. Like Chr(10) - line feed and Chr(13) - carriage return.
