To get the current Url without the query in VB.NET

Request.Url.AbsoluteUri.Split("?")(0)

This is a function code snippet to split a text in to two or more columns in VB.NET.

It is converted from my previous posted: Split text into multiple columns in PHP

Parameters:
InputString – String to be split into columns
Columns – Number of columns
SplitString – String to look for to not split midtext etc

Example of how to use:

        Dim strColumns As String() = SplitIntoColumns(strText, 2, "<h2>")
        strText = "<table><tr><td>" & strColumns(0) & "</td><td>" & strColumns(1) & "</td></tr></table>"

Code snippet:

Function SplitIntoColumns(ByVal InputString As String, ByVal Columns As Integer, ByVal SplitString As String) As String()

        '
        ' Splits a string into x number of columns and returns result as an array of columns
        '
        ' Parameters:
        ' $InputString String to be split into columns
        ' $Columns     Number of columns
        ' $SplitString String to look for to not split midtext etc
        '

        Dim Output() As String
        ReDim Output(0 To Columns - 1)

        ' Find middle of text
        Dim ColLength As Integer = Len(InputString) / Columns

        ' Split into columns
        Dim ColCount As Integer
        Dim Pos As Integer, LastPos As Integer = 0
        For ColCount = 1 To Columns

           ' Find $SplitString, position to cut
            Pos = -1
            If (LastPos + ColLength) < InputString.Length Then
                Pos = InputString.IndexOf(SplitString, LastPos + ColLength)
            End If
            If Pos = -1 Then Pos = InputString.Length

            ' Cut out column
            Output(ColCount - 1) = Mid(InputString, LastPos + 1, Pos - LastPos)

            LastPos = Pos

        Next ColCount

        Return Output

    End Function

[Edit: Updated function]

I made a Swedish shopping directory using affiliate links for a site and wanted to split it into two columns.

I wrote the following php function that can be used to split a string in two or more pieces. One parameter is at what character or string you want to split. For example if you want to split at a space to not break up words, or split at a period to not split up sentences, at certain html tags such as <h1> to keep headlines and text in same column etc.

The function returns a string array with columns.

Example how to use:

	$TextString = "some text to split")
	$Columns = SplitIntoColumns ($TextString, 2, "<h1>");
	echo ($Columns[0]);
	echo ($Columns[1]);

Function

function SplitIntoColumns ($InputString, $Columns, $SplitString) {

	// Source: http://blog.tjitjing.com
	// 
	// Splits a string into x number of columns and returns result as an array of columns
	//
	// Parameters:
	// $InputString	String to be split into columns
	// $Columns		Number of columns
	// $SplitString	String to look for to not split midtext etc
	//
	// Change history:
	// 2011-01-25/Max	Version 1
	//

	// Find middle of text
	$ColLength = strlen($InputString)/$Columns;

	// Split into columns
	for($ColCount = 1; $ColCount <= $Columns; $ColCount++) {

		// Find $SplitString, position to cut
		$Pos = strpos($InputString , $SplitString , $LastPos + $ColLength);
		if ($Pos === false) {
			$Pos = strlen($InputString);
		}

		// Cut out column
		$Output[$ColCount - 1] = substr($InputString, $LastPos, $Pos - $LastPos);

		$LastPos = $Pos;
	
	}

	return $Output;

 }
