[RESOLVED] Chr$

Hello everyone,
I was just going through this book I had about Internet Programming using Visual Basic 6.0.

I came across this code:

VB Code:

dq = Chr$(34)
sq = Chr$(39)

dq and sq are variables

The problem is that I don't understand what Chr$ does and I cannot find an explanation of it in the book. I looked up in the Object Browser of Visual Basic 6.0 and I get the following definiton:

Chr$: Returns a string containing the character associated with the specific character code

Format: Chr$(CharCode As Long)

Now I understand that it returns a string containing the character associated... But all I am attaching are the digits 34 and 39. By these digits seem to be some sort of Character Codes... Could someone please explain what Character Codes are and what these two mean.

Note: If someone can provide me with a list of all character codes and their explanations, I would really appreciated it.

Thank you all in advance.

The numbers that the Chr$ function accepts as a parameter are the numeric values of characters the way they are in the ASCII table.

The Long values represent the Ascii codes.

Try this in a new project:

VB Code:

'Place a ListBox on a Form.
'Will display All ASCII Characters
Option Explicit
 
Private Sub Form_Load()
Dim intIdx As Integer
 
    For intIdx = 0 To 255
        List1.AddItem "Decimal: " & intIdx & " = Char: " & Chr$(intIdx)
    Next
 
End Sub

The character codes are the ASCII values of the characters. 34 is the double-quote (") and 39 is the single-quote('). You can find a chart of them here. (Use the Dec values [the first column].)

Oh thanx a lot guys...
Basically what my program is trying to do is get the html tags. And since the location in the tags can be in double quoted (") or single quoted ('), the variables are being assigned the ASCII value of these... basically trying to find the link part of the html tag. Thanx a lot guys, I appreciate your help.
