any one ready to solve digital to analog conversion

[s.subbarayan]

Iam a nerd Vb programmer working in engineering field with Vb .I want to know how to do digital to analog conversion in Vb.I have asked the same question in my previous thread
also,but i couldnot get a reply.I am looking out for some one who helps me to solve the problem.I will feed the digital data(binary number) in a textbox and want the analog equivalent(decimal eq of binary number) in another text box.I need the coding also because Iam new to this sort of programming.The program must be general for any binary number irrespective of the number of binary digits.

The matter is very urgent.Kindly help me as soon as possible.I thank the person who helps me to solve it.

Any one with soln can contact me at:[email protected]

Loop through the text box right to left, character by character.

Delclare yourself a long or double variable.

When you find a "1" in the text box, set the bit in the long variable that corresponds to the current position in the text box.

eg:

Text in text box is "10110"

Select Case lPos 'lPos is the current position, 1 being rightmost
Case 1
    varLong = varLong Or 1
Case 2
    varLong = varLong Or 2
Case 3
    varLong = varLong Or 4
Case 4
    varLong = varLong Or 8
Case 5
    varLong = varLong Or 16
Case n
    varLong = varLong Or (n^2)
End Select

txtDecimal.Text = Cstr(varLong)

I've used a case to illustrate the technique, bu that is a bad way of doing it (cos you have no idea how long the binary string is. A better option is

lChar = The char to dela with
lPos = the curent position in the string

If lChar = "1" then
    varLong = varLong Or (lPos^2)
End If

That should work nicely (although I admit that I wrote that without testing it in VB)
