Sending Hex through Winsock

Does anyone know how to send "hex" through winsock? E.g. Something like...

Code:

---

HexData = 00 01 81 80 00 01 00 01 00 03 00 03 05 6C 6F 67
Winsock1.Senddata HexData

---

Or perhaps a function could help... such as...

Code:

---

Private Function EnHex(Hex as String)
'How could I code this?
End Function

Winsock1.Senddata EnHex("00 01 81 80 00 01 00 01 00 03 00 03 05 6C 6F 67")

---

Thanks. An example would be great.

How do you convert hex into string? That's another question I have. Thanks.

Hi,

I think you got some thinking to do here...

An HEX value is nothing diferent than an ASCII value, it's just the way YOU as a programmer see it in the variable.

Suppose you want to send these values to you socket

00 01 81 80

Winsock1.Senddata Chr(0) & chr(1) & chr(&h81) & chr(&h80)...

or you could have done this (which is exactly the same)

Winsock1.Senddata Chr(0) & chr(1) & chr(129) & chr(128)...

What you will receive in your winsock receive event is a string having unreadable caracters in it (little bars).
To have the value of this you must MID then ASC each of
the caracters one by one. value = asc(mid(str,1,1))

Perhaps I didn't understand your question but just I replied
just in case...

Bye

I am pretty new to hex values and I didn't know that they weren't ascii values. That helps me tremendously. Thanks!

How could you convert something like 6F into a Chr()?

Code:

---

Dim sHex as String
Dim sAscii as String

sHex = "6F"

sAscii = Chr(CInt("&h" & sHex))

MsgBox "The Ascii Value for " & sHex & " is (" & sAscii & ")"

---

In Visual Basic the value "&h" indicates a hex value. If you convert a string (where only numbers 0 to 9 and letters a to f are included) that has this at the front of it into an integer you get the equivalent ASCII value.

I would be VERY cautious of this however as any ASCII value < 32 could give you a control code and would give you strange results of ever displayed.
