I'm trying to read a byte array into a string however it's array is filling up from a dll in the following format. [Code] now its decoding the first byte but I think because of the next [0] it's not completing the whole array. This is the code that I'm using:
How would I copy/convert a string containing an ascii representation of hex values in to a byte array containing the actual hex values? For example, I have a variable containing the hex values delimited by spaces (I can change the delimiter):
I'm trying to read the binary data from a binary file with the code below but the it's return the value in the byte array. How can i read the binary data from the binary file and then convert the data into string?This is how i create the binary file.
Dim fs As New FileStream(Application.StartupPath & "Agency.dat", FileMode.OpenOrCreate) Dim bf As New BinaryFormatter() Call bf.Serialize(fs, GAgency)[code]....
I'm trying to get a string from a byte array previously read from memory
i can get the string like this
dim mem as string= ASCIIEncoding.ASCII.GetString(memory) or dim mem as string= UTF8Encoding.UTF8.GetString(memory) but when i try to concatenate this with another string i get a strange result dim result as string = "this is you memory string " & mem & " problem string" no matter what comes after mem in the concatenation it seems like it is not there when in fact it is because when i try this (mem has two chars in it) dim result as string = "this is you memory string " & mem(0) & mem(1) & " problem string" problem string appears so what i assume is that there are some vbCrLf chars in the string after reading (or is it from the conversion?)
I have a byte array that I convert into a string like so Dim byt As Byte() = New Byte(255) {} s = New String(Encoding.ASCII.GetChars(byte))My question is when I look at the string in a debuger its clearly a normal string but when I compare it to what I know its supposed to be it doesnt equal. So i did a quick check and for some reason its return a string thats the length of 256 characters. So i did a s.trim and it still is 256 characters long.
I have a client(VB.Net) that receives a packet from the server(Java), and for a while I struggled with some really weird packets that didn't make any sense, eventually took a look at the Java servers source and saw packet structures like this...

and so I came across the term of bit-masking. After a few failed attempts and unsatisfying google searches later, here we are.In short, I need to read a byte array bit by bit.
Is there any special way of reading a pdf file into a byte array? The reason I ask...I want to fax a pdf file using faxDocument and FaxServer. My current code is working fine for everything else. Now I know that in the documention it says it should not work for pdf. But I can get some pdfs to send and some do not. When I fax a pdf through windows, it works. [code]....
Some binary files have application variables at the end if you open it with a text editor you can see these variables. Now when I read these files into the processor memory the program does not work properly, however if I read a file without this it works fine. So how can I read a byte[] array to EOF so that when I pass that byte array into win32 api create-process it will create the process without corrupting the program?
I have a byte array and I want to read it using a structure. This is a common situation with structured files having information in various places in the file and it's much easier to read the data if it's mapped with a structure. BitConverter would be great if it worked with Structures, but it doesn't. Basically, I want to read the same memory address either as a byte array or as a structure, or have a function that works like vb.net MyStructure = BitConverter.ToStructure(bytearray(), position) Maybe there's a pointer method to do this?
I have an array defined As string and the value stored in site is like "7E", "A1" and so on. But in order to send out this array through serial port. I need to change the the array to As Byte instead of using As String. How can I convert it?
I'm trying to make an application that can read a 12 byte hex string from the serial port and display it into a text box, the source is a RFID module that is connected to my USB port using a RS232-USB converter.My first problem was accessing the text box in the datarecieved event due to invalid cross-threaded operation. Upon googling that, I copy/pasted the code I needed to get it work, these are all the cross threading functions.The OpenPort function and Datarecieved event are my own code, the rest I got off google. The application then worked, but I would get an incomplete code, the first swipe I would get all 12 digits, and at every other swipe, the first byte would vanish. Upon some more reading, I decided to make an array, the size of the incoming data (shown in the code below), but now I get the cross-threading error again.I know there's something wrong with the way I'm using the array. This is way beyond my VB knowledge, and I'm in o I'm an electronics engineer and self taught myself a little programming to create some apps for my hardware.Updated code:
Public Class Form3 Dim msg As String Private Sub Form3_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles
I try to read the ID3 Info from a .mp3 file by reading bytes, and then i convert it to a string, and try to compare it to a string (that contains the same word(s)) but wasnt a byte stream beforehand anyhow ALL of my converted strings have a length of 31, regardless of if its a string that says "John" or a string that says "Teenage Mutant Ninja Turtles" how can i make my converted string have the correct length? John = 4 NOT 31!!??
I have an activex control that outputs a template object to the client, which gets serialized to a byte array. My attempts to put this byte array in a hidden field for post back to the server have given mixed reults, in that the size of the byte array decreases when sent to the server. My best guess is that the byte array is being truncated when put into a (string) hidden field.
I convert the byte array to a HEX string on the client side before passing over to the server, then converting it back on the server - HEX to byte array. If found some examples of how to do this in C#, VB.net but I haven't a clue how to accomplish this on the client - vbscript, javascript, etc,
I'm guessing something like this would get it done on the server, but how would I accomplish this on the client side?
Private Function Bytes_To_String2(ByVal bytes_Input As Byte()) As String Dim strTemp As New StringBuilder(bytes_Input.Length * 2) For Each b As Byte In bytes_Input
When I use Return Convert.ToBase64String(ms.ToArray()), I can decrypt data by first Convert.FromBase64String(stringToDecrypt) and it works fine.
But if I dont use Base64string method when returning the data and use .Encoding.ASCII.GetString(ms.ToArray) and then try to decrypt, I get "Bad data" error
I am working on a mini project that requires me to take a 8 byte hex string that I received from the Serial Port and convert it into a Byte Array and display it on the screen.An example of the string that I receive is 01050001FFFF8FFB
I am currently using the System.Text.ASCIIEncoding.ASCII.GetBytes(str) to help me achieve this. However I realised that if this does not support extended ASCII so whatever byte that is > 7F, I will not get the right value.My current code is as follows:
vb Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived Dim str As String
I'm trying to figure out how to convert a string inot a byte array to send as a packet over a socket. Initially it was used for serialport.write but I would like to use in Socket.BeginSend(ByVal buffer() As Byte buildpacket() Below is taking a struct (listed at bottom) as an argument and building a string using eg. Chr().
How can I convert the output of buildpacket(), eg. "yyyypyu" into a Byte(). Public Function buildpacket(ByVal packet As PacketRecord) As String Dim temppacket As String Dim checksum, i As Integer 'Build packet to Transmit temppacket = Chr(255) & Chr(255) & Chr(255) & Chr(255) & Chr(254) [Code] .....
I'm writing a C# application that reads data from an SQL database generated by VB6 code. The data is an array of Singles. I'm trying to convert them to a float[]
Below is the VB6 code that wrote the data in the database (cannot change this code):
Set fso = New FileSystemObject strFilePath = "c: emp emp.tmp" ' Output the data to a temporary file
[Code]....
The problem here is the VB6 binary to string conversion. The VB6 string char is 2 bytes wide and I don't know how to transform this back to a binary format I can handle.
Below is a dump of the temp file that the VB6 code generates:
And here is the dump of the data as I read it from the database in (=the VB6 string):
I have to set a value in the registry and it has to be in a unicode binary format. This is to change the default signature of Outlook.I have a signature called : TacoWhen I change my default signature in Outlook itself to Taco. It will be stored in the registry like this:54 00 61 00 63 00 6f 00 00 00However, when I change the value of this key programmatically like this:
This illustrates a series of bytes that I've received from a socket and assigned into a byte array (frameData). How do I extract the ascii string from frameData if FrameData.Length is 79 bytes long and I need to extract the byte locations whose begin -frameData(26) and end frameData(44) are given by the arrows I've drawn?
Im still going with a small app im doing and i have the byte data currently in a string array and i would then like ot use that in the below line but the underlined bit gives the error:
