How can I give the latitude and longitude values in the link after q=

I need to get the Lat + Lng values instead of q=51.28333299869885+4.416667002695409&t=h&z=17

VB

Private Sub Cmd_Openinmap_Click(sender As Object, e As EventArgs) Handles Cmd_Openinmap.Click
        Dim Lat As String = Txt_Map_Latitude.Text
        Dim Lng As String = Txt_Map_Longitude.Text

        Process.Start("http://maps.google.com/maps?q=51.28333299869885+4.416667002695409&t=h&z=17")
    End Sub

Please Guide

Just to confirm, is the question really about concatenating strings in VB.NET?

Solution 1

A mix of techniques: Regex [^]and Split [^]

Imports System
Imports System.Text.RegularExpressions		
Public Module Module1
	Public Sub Main()
	Dim querystring As String = "q=51.28333299869885+4.416667002695409&t=h&z=17"
	Dim pattern As String = "(?<=q=)\d+\.\d+\+\d+\.\d+(?=&)"
	Dim m As Match = Regex.Match(querystring, pattern)
    Console.WriteLine(m)
	Dim latlng As String() = m.ToString().Split(New Char() {"+"c})
	Console.WriteLine(latlng(0))
	Console.WriteLine(latlng(1))
	End Sub
End Module

Private Sub Cmd_Openinmap_Click(sender As Object, e As EventArgs) Handles Cmd_Openinmap.Click
Dim Lat As String = Txt_Map_Latitude.Text
Dim Lng As String = Txt_Map_Longitude.Text
Process.Start("http://maps.google.com/?q=lat+lng&t=h&z=17")
End Sub

Run my sample code in a console to understand it.
