Unicode Text Byte Array?
Apr 23, 2009
At me soon the roof will go, I can not solve one problem.The problem consists in the following, I accept sms through components devshock, in unicode a format.The message text comes back in an array from bytes in a following kind, we will tell: byte: (4, 18).Though if to translate unicode the text in VB.NET as follows:
Encoding.Unicode.GetBytes(<text>) the array of such kind comes back: byte (18, 4), i.e. on the contrary.And so all text.How it is possible to transform the given file to a normal, convertible kind?

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:
vb
.SetValue("New Signature", Text.Encoding.Unicode.GetBytes("Taco"), Microsoft.Win32.RegistryValueKind.Binary)

I have a text box that I will paste into a byte array, for example:
02 01 05 BF DD 03
All I need to do is when I click on a button, for the program to take the length of the array and store it in RCVDMSG_Length() and then take the contents of the text box and put it into a byte array RCVDMSG(). From there I think I can figure out how to manipulate the array... but it's this first step that I'm stuck on....
So far I have this in my Form:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim RCVDMSG() As Byte
Dim RCVDMSG_Length() As Integer
RCVDMSG_Length = Len(TextBox1.Text)

I have a simple byte array: Dim TheBuffer() As Byte={0,1,2,3} and I want to store it to a TEXT file. Is there any simple way of doing this? I want to enter the text file and see the array 0,1,2,3. don't want binary format etc.

I have 2 byte arrays. I want to merge these two byte array into 1 byte array.Usually, I just create a new byte array with length = byte array #1 + byte array #2. Then copy byte array #1 and #2 to the new byte array.do I have more efficient way to merge 2 byte array using VB.NET and .Net 4?

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 am trying to get a count of all the times a byte sequences occurs in another byte sequences. It cannot however re-use a bytes if it already counted them. For example given the string let's assume the byte sequence was k.k it would then find only 3 occurrences rather than 5 because they would be broke down like: [k.k].[k.k].[k.k]. and not like [k.[k].[k].[k].[k].k] where they over lap and essentially just shift 2 to the right.
Ideally the idea is to get an idea how a compression dictionary or run time encoding might look. so the goal would be to get down to just 2 parts, as (k.k.k.) is the biggest and best symbol you can have.
Here is source so far:

I didn't think it fair to post a comment on Fredrik Mörk's answer in this 2 year old post, so I thought I'd just ask it as a new question instead..NB: This is not a critiscm of the answer in any way, I'm simply trying to understand this all before delving into memory management / the marshal class.
In that answer, the function GetByteArray allocates memory to each object within the given array, within a loop.Would the GetByteArray function on the aforementioned post have benefited at all from allocating memory for the total size of the provided array:
Dim arrayBufferPtr = Marshal.AllocHGlobal(Marshal.SizeOf(<arrayElement>) * <array>.Count)
I just wonder if allocating the memory, as shown in the answer, causes any kind of fragmentation? Assuming there may be fragmentation, would there be much of an impact to be concerned with? Would allocating the memory in the way I've shown force you to call IntPtr.ToInt## to obtain pointer offsets from the overall allocation pointer, and therefore force you to check the underlying architecture to ensure the correct method is used*1 or is there a better way? (ToInt32/ToInt64 depending on x86/64?)
*1 I read elsewhere that calling the wrong IntPtr.ToInt## will cause overflow exceptions. What I mean by that statement is would I use:
Dim anOffsetPtr As New IntPtr(arrayBufferPtr.ToInt## + (loopIndex * <arrayElementSize>))
I've read through a few articles on the VB.Net Marshal class and memory allocation; listed below, but if you know fo any other good articles I'm all ears![URL]..

How do I Extract all Characters in Unicode, UFT8,iso-8859-1 to 9 etc to a list or array In VB?I have a SQL Database of which contains values from 51 languages. I need to detect which ISO-8859-? Was used to encode the string value. For example Turkish Characters i.e. "Ö Ş ş ğ ü Ç" Once I have the correct ISO, I need to convert the Chars with-in the string to Unicode using only if the string value contains values that are not UFT7, and convert the string to HEX?The reason I need to detect the ISO etc is because we are sending SMS, of which jump from 160 characters to 70 if a special characters are used, i.e. "Ö Ş ş ğ ü Ç" Is there a simple way to extract the ISO-8859 Character Set to a Array etc, or is there a simple way to check if the character exists with a ISO-8859 data set?

The following image or RTF file illustrates how I'm trying to transform an input Byte array into an output array of Booleans. This is basically what I have listed below. figure out how to get from one array to the next while shifting values of bytes within 8 byte groupings to shift low order to high order or vica versa. What I mean by that is best seen by looking at the illustration of actual input an required output. The reason for this is that the hardware devices have registers and the display which can be seen in the links above needs to convey the disabled sensor cable cell locations.

The code below contains the actual data I receive as input and the required output to send to a hardware device. The application requires incoming boolean values be processed in sets of 8, corresponding to their resultant Byte value. The first incoming boolean value must assume the least significant position of the resultant Byte Value. False, False, True, True, True, True, True, True will result in a Byte Value of 252 if viewing the resultant Byte value in the debugger. Those boolean values will be reversed in order to become True, True, True, True, True, True, False, False. What I can't figure out below is how to accomplish this in the form of masking or shifting the values to accomplish this.

I am trying to convert text inputed in a text box to unicode. I need to the program to process each letter and return "the letter = the unicode" in the label.
For example, if the user enters "apple" the lable would read: a=65 p=80 p=80 l=76 e=69
I know the AscW command will return the Unicode Integer but I only know how to do the conversion for single letters
The code below only processes the first letter and only returns the code, not "the letter = the code"
