I have lines of text that contain "degree symbols" (ASCII(248)). I want to replace those symbols with an alphabet character (Z).I am changing the line of text into a charArray,iterating through one character at a time. How do I define the ASCII(248) in code to replace each occurence with a Z? Something like string.Replace(ASCII(248), "Z") would be nice, but that doesn't seem to work too well.
View 4 RepliesI'm trying to convert an ASCII String to hex for VB 2008. So far I have this :
Code:
Function asc2hex(ByVal StrName As String) As String
Dim loopCount As Integer, strHold As String
For loopCount = 1 To Len(StrName)
strHold = strHold & Hex(Asc(Mid(StrName, loopCount, 1)))
Next loopCount
asc2hex = MsgBox(strHold)
End Function
However, It is not reporting all the bytes that it should be. For example: This is the correct format.

I need some thought input on how I can take my string of HEX values and convert them to ASCII according to the specifications below: A function would be ideal since I need to quickly decode about 250 records all having 20 thresholds to record.[code]

View 3 RepliesHow to correctly convert string containing upper ASCII characters to byte array besides looping through each character and filling the array using AscW(chr)?I know I can do something like:
Code:
Dim bSourceData As Byte() = System.Text.ASCIIEncoding.GetBytes(sourcedata)
But this only works for lower ascii characters (0-127).Instead of ASCIIEncoding I can specify encoding myself (System.Text.Encoding.Getencoding(encoding).GetBytes(sourcedata)). But I have to specify correct encoding in this case, otherwise most of special characters are converted to "?". What should I do if I don't know the encoding?

View 6 RepliesNeed to get this done: To have just ONE cell that is defined in a dropdown list with several (various) countries� currencies, and each time when I choose a currency on this dropdown, EVERY cell in my worksheet which has a figure formatted with CURRENCY will automatically turn into that currency selected only in that dropdown cell. I have imagined whether if there was a solution, that the monetary cells do not necessarily have to be first in CURRENCY format, or do they have to? Anyway, I do nt know how to accomplish this, Without the solution, I have still at this time just set all the cells with monetary amounts in simple NUMBER format, ie. no CURRENCY SYMBOL at all, till I find a solution ..

I need the data to be in Hex
This has been driving me crazy for two weeks! I just started learning Vb.net, so please forgive me if I make rookie mistakes. Basically, I would like to convert any type of file to Ascii code. An mp3, .wav, .avi etc. The most I was able to do is convert only the first character of the file to Ascii. Also, I'm not sure what would be the fastest method to do this. SteamReader, FileStream, or BinaryReader. Can anyone explain what method would be best? This is what I have so far:

View 2 RepliesI'm testing a "simple" login program: it has predetermined ID and Password, after input is correct then you can change the ID and Password. It saves a Non-Encrypted file that has the new ID and Password. Then after the program loads (when it is opened again) it reads the file to retreive the ID and Password, but when it reads, it reads it in 32-bit code, I need it in Ascii (with alphabetical representation) so that I can compare it to the input.I also get an error stating the length cannot be a negative (right after my comment).

View 9 RepliesI have a string of text being sent through a serial port to a text box (Text1.Text). The string has some symbols in in which I am assuming are Hex values. The hex values are Hex(1), Hex(4), Hex(12), and Hex(17). What I need to do is find the position of these hex symbols in the string of text so that I can split or grab the data after the specific hex symbol. I am not able to use substring or indexof or instr ... or at least I am not using it correctly to find the appropriate symbol.I was thinking if I need to iterate through the string character by character and grab each symbol or text and get their value??? If it is one of the hex symbols, then get the index number (or position).
