Hi again: 1. Yes it can be used for any unicode character between 0 and 65535. For example ChrW(2) represents the non-printing character which in the single byte ASCII system is called STX (start of text). 2. No it's not compulsory to use hexadecimal for the argument - it's more usual to use a decimal integer.

hi thanks aneway 1.can this function convert any other char code to unicode eg. isfoc to unicode 2. and is it compulsory to give hexadecimal as input  cant we give simple number! :(

Alan · Answer

The ChrW function returns the unicode character with the same number as its Integer argument. For example: Dim c As Char = ChrW(65) 'assigns the variable c the character 'A ' This line does the same except the argument this time is expressed as a hexadecimal number: Dim c As Char = ChrW(&H41)
