C# - Conversion From VB6 String Data To .NET Byte Array
May 7, 2009I'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):

View 1 RepliesConvert A Byte Array From Socket Into A String To Replicate - How The Serial Port Receives Data
Sep 21, 2010I've inherited a tested function that processes incoming data from a .NET Serial Port. (Dim RXBuffer as string = serialport1.ReadExisting) I've written a different part of the application that processes a byte array as received from an asynchronous .NET socket.
Is there a way I can convert the byte array into a string as if it arrived from the serial port?
I would prefer to rewrite a very long 'if statement' into byte array functions syntax that look like:
dim b as boolean = IsBitSet(state_buffer(i), j) 'rather than:
dim b as boolean = (Asc(Mid(RXPacket.Pdu, CInt((i - (i Mod 8)) / 8) + 1, 1)) And CInt(2 ^ (i Mod 8))) > 0

View 3 RepliesConvert Byte Array Into A String Like So Dim Byt As Byte()?
Jan 25, 2011I 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.

Jul 1, 2009I have to text file in the following format :
Word[tab][tab]Word[Carriage Return]

I want to get all the words before the tab into one array or to create a new text file and the all the words after the tab into another array or create a new text file too.
Here my function to get the words before tab into an array :

I wrote the above function to get all words before tab but I got all the words into array. I've been trying to use the Split method above. What is another method to split those words ?
I know this can be done with regular expression but I don't know regex yet. If you can show me how to get this done with regex it'll be awesome.

DateTime Binary Coded Decimal Byte() Equivalent Of String Format?
Sep 30, 2010I realize the code listed below, whose serial port using string formatting which I inherited is complicated. It formats a Date obtained from a DatePicker control into a "yyyy-MM-dd HH:mm:ss" string format to send to a hardware device to be stored via Serial Port retrieves the date from the device and displays to user What I'm trying to do is port the code for use in a Socket rather than Serial Port which wants a Byte Arrray of the same Date Time string variable. I can't figure out how to encode and convert to Bytes the string value used in the Serial Port version. The evolution of the process is listed from top to bottom.

Convert Byte Array To Hex String?
Aug 12, 2009I 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?

Converting Hex String To Byte Array?
Mar 8, 2011I 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:
