Convert ASCII To Char?
Feb 15, 2009
I have a string of ASCII in HEX. ( 5A65726f)so first i split them into 2s >>>> 5A 65 72 6f then i change the hex to integer using these integer i convert them to char using chr() it did the job great, i can see the correct word i want..but it give me an error saying " make sure it has the right format" ( error shown below)
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim hexnum As String
Dim converttohex As String
Dim hextonum As Integer
[code]....
i thought it was the for loop problem...since i will go up to 7 while len(hexnum) is 8 so it would loop again but there is nothing after 8th HEX?so i tried For i = 1 To Len(hexnum)-1 Step 2 ...this time...textbox didnt show anything...+ the same error came up...

This is my code:
origen = RichTextBox1.Text.ToString
Dim valor As Char() = origen.ToCharArray
Dim numeros As Integer() = (How can i convert "valor" to an int array?????)

I read in a unique file type, its called .pkm, it's just a collection of hex data. Anyways, I'm using VB Express 2005 (or 2008 since it's free), and I read in the file, and printed out the values. It printed out the ASCII character equivalent, so all I saw were the weird symbols and all (the hex characters in this file do not convert using ASCII). What I want to do is convert it to hex so I can see what the hex values are.
Code:
Dim file As String
Dim data1 As String
file = "D:Documents and SettingsownerDesktopPokemon7-10-08_10ANNIV_ENG_Lugia.pkm"

Too bad image code is off. That is a screen from a hex editor that reads it in properly. Currently my program displays it the way it is seen on the right, but I need it displayed the way it is on the left, in plain hex.

Simple question, what would be the optimum code in VB2010 to read in a text file and verify that:1) It is a text file, and2) There are no non-ASCII characters anywhereAnd conversely, we would want the code to provide a warning if the file is not a text file, or if the text file contains non-ASCII characters. [Note that LF, CR and EOF are expected to be in the text file, and should not be flagged as errors]

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:

I'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).
Here is my code:
Imports System
Imports System.IO
Imports System.Text

I realize this might be a redundant post, but I can't seem to find (through all the searches) the code to do what I need to do...or it's just not working for me.
I have an Intel hex file (containing ASCII characters) such as :041400000262F5226D
I need to convert the values to hex numbers into memory (an array), such as

I'm not sure of the proper combination of conversions I need to get this accomplished. I've tried several combinations of Val/Asc/ etc. but can't get it correct.

=CHAR(HEX2DEC("c7")) will return, 'Ç'
Is there any library function, which does the same, in .net

My application is reading in data from the serial port. The packet format uses 1 byte to tell the data length. The problem is as I am reading each byte in as a char when I try to get the value of the received character (using Asc(cRxd)) it only works up to values of 127, any bytes received that are over 127 are received as 63. I noticed that this was the default parity replace value, but I have parity.none set and I also changed the parity replace value. The received byte is always 63. I have tried reading the data using .ReadByte but this gives the same result - only works on values below 128.

I'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'm not exactly sure if this is the correct question to be asked but I will tell you what I am attempting. I have an ASCII txt file with product data in it. It does not have headers. I am looking for a way to convert this data into an XML file, however, I want it to parse through one of the txt fields to incorporate a look-up field and modify the data based on that field. Now I could use VB.NET, C# or Javascript. Example provided:
