so that I can sort Arrays of Structures? What I'm asking is how do I convert a String.Substring(index = 0, length = 1) to a Number that is ASCII integer 0 - 127 ASCII will this module work?
Public Function IsInteger(ByVal strValue1 As String, ByVal strValue2 As String) As Boolean

how do I convert the string to Binary 0 - 127 ASCII code...
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]

View 14 RepliesI'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml
The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.
The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:

How will I select a substring with 2 criteria? I have a Richtextbox where I select a number after a : with this code; For Each line As String In Richtextbox1.Lines Dim equalsPos As Integer = line.IndexOf(":") + 1 txtFound.AppendText(line.Substring(equalsPos, line.Length - equalsPos)) Next This is working ok, but the whole line.length is appended for number2. The line ex. Some text:my number some text-my number2. I want my number appended to txtFound, and my number2 appended to txtFound2. With my code only number2 can be appended correct.

I'm testing a "simple" login program: it has predetermined ID and Password, after input is correct then you can change the ID and Password. It saves a Non-Encrypted file that has the new ID and Password. Then after the program loads (when it is opened again) it reads the file to retreive the ID and Password, but when it reads, it reads it in 32-bit code, I need it in Ascii (with alphabetical representation) so that I can compare it to the input.I also get an error stating the length cannot be a negative (right after my comment).

View 3 Repliesbut I am trying out VB.net and is trying to make a program to show the ascii code for every key press I made.. here is the coding i used..
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As _ System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
TextBox2.Text = e.KeyValue
End Sub
this one seems to work fine, but I noticed that regardless of whether I use "A" or "a", the ascii code shown is always 65. last i checked small letters have their own ascii code, so "a" should show a ascii of 97, not 65..

I am working on a client/server based application and I have run into quite a few snags stumbling my way through I have resolved quite a few issues, and need help with something new. I am using a TCPIP client/server and I find that at the end of each loop when I am reading the data from the network stream it appends a character to the end. I have tried removing the last character but I am not sure if it is getting the whole character successfully because I still get lots of different errors both in binary and xml deserialization whcih I think is related to this. Does anyone know the ascii code for the termination character for TCPServer/Client communications?

View 1 RepliesSo I have an ASP.Net (vb.net) application. It has a textbox and the user is pasting text from Microsoft Word into it. So things like the long dash (charcode 150) are coming through as input. Other examples would be the smart quotes or accented characters. In my app I'm encoding them in xml and passing that to the database as an xml parameter to a sql stored procedure. It gets inserted in the database just as the user entered it.
The problem is the app that reads this data doesn't like these characters. So I need to translate them into the lower ascii (7bit I think) character set. How do I do that? How do I determine what encoding they are in so I can do something like the following. And would just requesting the ASCII equivalent translate them intelligently or do I have to write some code for that?
Also maybe it might be easier to solve this problem in the web page to begin with. When you copy the selection of characters from Word it puts several formats in the clipboard. The straight text one is the one I want. Is there a way to have the html textbox get that text when the user pastes into it? Do I have to set the encoding of the web page somehow?
