Remove A Set Number Of Characters Before Each Line Received?
Nov 16, 2010
I'm currently building a Terminal Emulator and can read RS232 data ok into a Textbox.
However, I want to remove a set number of characters before each line received.
I've got so far with StringBuilder but my code is wrong somewhere as it cuts out every other line.
The original text looks like this:W 320:15:25 0300 SAMPLE FLOW WARN
T 320:15:25 0300 CO= 4.6 PPM
T 320:15:25 0300 RANGE=50 PPM
T 320:15:25 0300 STABIL= 0.0 PPM
T 320:15:25 0300 CO MEAS=4012.0 MV
T 320:15:25 0300 CO REF=3457.3 MV

How do I limit the number of characters per each line of an RTB to 1 char per line? That is you type one character, after that the textbox should not accept further input on that specific line.-Knock knock -Who's there? -(looong pause..) Java

I have a RTB which I import with a set of 7 or 9 didit numbers, 7 for Staff and 9 for Students. e.g. Staff numbers [code]and depending on what is selected in a list box ('Student' or 'Staff') will generate a string to create user accounts. To further error check I would like to check if a line in the RTB = 7 And Listbox = "Student" Then msgbox("Data mismatch between User ID and Account type")

i am getting the above and i can not see where the '_1' are getting added. I don't want to mess too much with it incase it stops working the way i need it too. The lines in bold are the ones that write the results to a .tmp text, see below.

I am retrieving string values from a table and then encode each term to make a httpwebrequest to an api. It works fine and the terms allow for foreign characters like japanese/arabic/chinese etc and these are inserted fine. The problem occurs when some of these terms contain weird characters and that is when the request is bad. The only reason it is bad xml and the template I follow gets invalid are when these characters are present. I use the
system.securityelement.escape
And also
httputility.htmlencode
As part of my cleanup. One of the weird characters ends up appearing as a space but it is not since the trim(term) does not work and when I look at the xml in visual studio it looks like an ' &' with arrow pointing up attached to it. It does not appear after I pasted it here.It appears as a line feed or carriage return and I have tried to remove that too. Anyway is there some way I can ensure that these sort of characters are removed and if I were to use the binary values like <32 invalid, will foreign characters then get excluded.
temp = temp.replace(vbCr, "")
temp = temp.replace(vbLf, "")
temp = SecurityElement.Escape(temp)

I'm currently stuck on something I need to have done for my application. I have a listbox where I have a lot of urls in the following format: [URL] With the quotes on it. Now I want only these links to remain in the listbox and to remove the quotes and rl around it. I tried using regex but it didn't worked out for me.

I made a batch script using VB.NET which deletes shortcut on my desktop. The problem is that shortcut title contains unicode characters so batch doesn't work. However if I remove that unicode character from the shortcut and batch script it does delete the shortcut. How can I make it delete the shortcut w/o removing that unicode character?
tempstring = "@echo off"
tempstring = tempstring & vbCrLf & "del " & Chr(34) & My.Computer.FileSystem.SpecialDirectories.Desktop & "My shortcut™ 1.lnk" & Chr(34)
tempstring = tempstring & vbCrLf & "del %0"

bytes ( 00 00 00 ) I'm trying to remove from a specific set of locations within a byte stream. The following code is what I'm using. I tried using the Trim function as listed in the code at the bottom but that had no effect. I'm extracting from a fixed byte range and there are null values after the end of valid ascii characters. Dim temp() As Byte = GetByteArray(FrameData, 3, 32)
Private Function GetByteArray(ByVal MyArray As System.Array, ByVal Start As Integer, ByVal Length As Integer) As Byte()
