Experts, I need help searching through a string and converting ascii hex values to characters. Below is the string i need to parse. The ascii hex values are preceeded by % and I need to replace this with the character value. For example in the &email tag I need to replace %40 with @.


string contents:
dim str as string
-----------------------------------------------------
str = customer_id=255349&authorized=no&first_name=test&last_name=order&phone=5618662933&email=test%40test.com&product=50&username=&password=&shipping_address=1124+apollo+rd&shipping_unit=1124+apollo+rd&shipping_city=Melbourne&shipping_state=FL&shipping_zip=32935&shipping_country=US&billing_address=1124+apollo+rd&billing_unit=1124+apollo+rd&billing_city=Melbourne&billing_state=FL&billing_zip=32935&billing_country=US&cc_number=5454545454545454&cc_expires=2011-05-30+23%3A59%3A59&cc_name_on_account=test+order&cc_ccid=123

Not efficient, but it works:

For i = 0 To 255
    str = Replace(str, "%" & Right$("0" & Hex$(i), 2), Chr$(i))
Next i
0

This is cutting off the end of the string at position 425? It is changing what it leaves to the character code.

Do you still have a truncating problem. I can't reproduce it myself?

Rather than breakdown the whole string im going to try parsing the tags which should work. You might be able to answer my other question though
