C# - Remove Duplicate Char On String (more Than 3 Occurrences) Using Regex?
Jan 13, 2012I'm sorry if it's a duplicate of some question but this is specific on Vb.Net Regex function.
I need to remove any occurrence of 3 or more duplicate characters on a given string. For example:
Dim strTmp As String = "111111.......222222 and 33"
Dim output As String = Regex.Replace(strTmp, "????", "")
Debug.Print(output)
The "????" part I guess should be the Regex expression, which I must assume I know almost nothing about.
I don't know if that's the correct syntax. But I need the output to come as:
"1.2 and 33"

Why Is String Returning A Char
Jun 27, 2012I have built a DataTable from my database. Then I am looping through the rows and trying to access a string, however the value is being returned as each character in the string.

If theseRows.Item("Last_Name") = userLast And theseRows.Item("First_Name") = userFirst Then

The Trap_Code values are two or three letter strings, the returned value is each letter once at a time. The loop seems to cycle through the individual characters of the string as an array rather than display the entire value, which is what I was hoping for.

Using Char - First Letter Of String Must Be Certain
Apr 18, 2010Basically the first letter of a string must be a certain letter. At the moment the only way I know how to do it is as follows:
If sConsignmentNo(0) = "J" Or sConsignmentNo(0) = "C" Or sConsignmentNo(0) = "U" Or sConsignmentNo(0) = "N" Or sConsignmentNo(0) = "H" Or sConsignmentNo(0) = "S" Or sConsignmentNo(0) = "V" Then
Basically listening the same thing out over and over. Is there a way I can say, If sConsignmentNo(0) = ListOfValidEntries i.e J,C,U,N etc?

Import And Call Unmanaged C Dll With Ansi String "char *" Pointer String From .net?
Mar 11, 2010I have written my own function, which in C would be declared like this, using standard Win32 calling conventions:int Thing( char * command, char * buffer, int * BufSize);I have the following amount of VB figured out, which should import the dll and call this function, wrapping it up to make it easy to call Thing("CommandHere",GetDataBackHere).UPDATE:This code is now a working solution, as shown here:
Imports Microsoft.VisualBasic
Imports System.Runtime.InteropServices
Imports System
Imports System.Text
[Code]...
Updates: I got the code to build by following the help received here, and then I had forgot the As Return Type (which got me a MarshalDirectiveException PInvokeRestriction). Then I had an assertion failure inside my DLL, which lead to an SEHException. Once fixed, this works BEAUTIFULLY. There are newsgroups where people are saying this can not be done, that VB only loads managed dll assemblies (which I guess is the normal thing most VB users are used to).

String / Char Arrays And Whitespace
Feb 6, 2012I am developping an app which talks across a network and will eventually be used to read in a text file (on the client) and transfer it to the server. Currently, the server and client succesfully connect to each other using the Tcplistener/Tcpclient classes. I am now trying to send some data across the network using the networkstream class, which I have implemented.Currently for testing purposes i am sending a char array which contains the characters "hello" which succesfully sends and outputs to console on the server. Although, "hello" is followed by a long list of whitespaces. I have tried converting this to a string array on the server and/or client and using the string.Trim() function (amongst trying many other things over the past couple of hours) although the output remains the same.
