I am receiving ASCII data over my serial port. "51 48 46 48 48 49" for example, this represents my temperature of 30.001 degree. Now I would like to convert this ASCII numbers nad combine to readable temperature and store my data into an excel table. [Code]

How to convert byte array to ASCII in VB.NET System.Text.Encoding.ASCII.Getstring(y) it gives the data like 52414D41 . but i need "RAMA" instead of 52414D41.
View 6 RepliesI read parameters from my ECU thru RS232 and display them on TextBox. But the display is ASCII instead of itself. E.g. I read 0x01 and store it in DataReceived, and set
Dim DataRecevied As Byte
TextBox1.Text = DataReceived
The value appeared in TextBox1 is 49 (0x31), which is ASCII of 0x01. How to display 01 there?

How 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 3 RepliesI am simply trying to get the hexadecimal value of an integer (below 255) and then place this value into a byte. I have been using the hex command, but it converts the value to a string hex value. Its been driving me mad for days now as I just cant seem to sort it!

View 2 RepliesI'm trying to make to do a widening conversion from a byte to an integer. form has a text box for both Input, and Output, plus a conversion button. [Code] I'm trying to use a catch block, but I'm not certain how it works exactly, and also tried to use an If statement to avert the issue, but that didn't work either. When ever user inputs a number greater than what can be held within the Byte data type the program crashes from the run time error.

View 19 RepliesI am new to vb net so please cut me some slack if this is a stupid question, I have always used vb6 before, but finding that its less and less supported so trying to learn vb.net by myself. Also I am doing this for a hobby not a profession.I am writing an Console application to read a file sequentially 1 byte at a time into a 1 byte buffer. It then copies that byte into a 4 byte lookup buffer, that moves, ie as the file pointer moves forward by one byte the 4 byte lookup buffer copies the last 3 bytes into the first 3 bytes to accept the byte at the file pointer into the 4th byte of the lookup buffer. I am doing 1 byte at a time because the data I am looking for is not at pre-determind offsets and filesizes may not be a multiple of 4.

Help please its driving me mad It appears as if the byte is not being transferred to the lookup buffer so that it would always be 0, either that or I am not converting it to an integer properly
I am reading/writing a fixed length header into a stream and I need to do the following in VB:
1. Convert a 2 byte integer (int16) into a byte array
2. Read 2 bytes of a byte array into an integer variable
I have a very simple question about converting a byte array into 16bit integers. I am connected to a device through a serial port. It sent me six bytes which represent three Int16 integers. For example, the byte array is called newRecievedData(5) and has a length of 6.
The manual that came with the device claims that the int Format is 8 bit MSB|8 bit LSB. Does that mean the following?
newRecievedData(0) contains 8 high bits of the first Int16
newRecievedData(1) contains 8 low bits of the first Int16
newRecievedData(2) contains 8 high bits of the second Int16

I need to parse a binary stream in .NET to convert a 16 byte unsigned integer. I would like to use the BinaryReader.ReadUIntXX() functions but there isn't a BinaryReader.ReadUInt128() function available. I assume I will have to roll my own function using the ReadByte function and build an array but I don't know if this is the most efficient method?
View 3 RepliesI inherited a project that includes a dialog between two applications. One in native C++ the other in VB.NET. The protocol is such that the first 4 bytes (32 bits) of the message encodes the size. However the VB.NET side never sets these first four bytes, however it does use the .net method BeginSendTo, which accepts an argument for size. Does the BeginSendTo method automatically add the size to the beginning of the message in the form of a 4 byte int?

I have tried all of the encodings in the System.Text.Encoding package with no luck. I thought I had it with UTF7 but it was dropping other characters like replacing the + sign with a space.
