Hey DreamForums,

Public Sub New()
          Dim fbdserver As FolderBrowserDialog
    Dim fbd1apache As FolderBrowserDialog
    Dim fbd2mysql As FolderBrowserDialog
    Dim fbd3 As FolderBrowserDialog

  MyBase.New()

        fbdserver = New FolderBrowserDialog
        fbd1apache = New FolderBrowserDialog
        fbd2mysql = New FolderBrowserDialog
        fbd3 = New FolderBrowserDialog


    End Sub

[b]Button:[/b]

Private Sub ServerPathButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ServerPathButton.Click
        fbdserver.ShowDialog()
        If (fbdserver.SelectedPath <> "") Then
            ServerPath.Text = fbdserver.SelectedPath
            My.MySettings.Default.ServerPath = fbdserver.SelectedPath
            My.MySettings.Default.Save()
        End If
        CheckPaths()
    End Sub

[b]CheckPath:[/b]

 Private Sub CheckPaths()
        If (File.Exists((ServerPath.Text & "\authserver.exe")) AndAlso File.Exists((ServerPath.Text & "\worldserver.exe"))) Then
            isServerPathCorrect = True
            ServerPath.BackColor = Color.LightGreen
            StartWorld.Enabled = True
            StartAuth.Enabled = True
            StopWorld.Enabled = True
            StopAuth.Enabled = True
            AutoRestart.Enabled = True

           
         ' //  Both are Object reference not set to an instance of an object
            worldServerInfo.WorkingDirectory = ServerPath.Text
            authServerInfo.WorkingDirectory = ServerPath.Text

            worldServer.StartInfo = worldServerInfo
            authServer.StartInfo = authServerInfo
            

          
         
        Else
            isServerPathCorrect = False
            ServerPath.BackColor = Color.LightCoral
            StartWorld.Enabled = False
            StartAuth.Enabled = False
            StopWorld.Enabled = False
            StopAuth.Enabled = False
            AutoRestart.Enabled = False
        End If
        If File.Exists((MySQLPath.Text & "\mysqld.exe")) Then
            isMysqlPathCorrect = True
            MySQLPath.BackColor = Color.LightGreen
            StartMySQL.Enabled = True
            StopMySQL.Enabled = True
            mySQLInfo.WorkingDirectory = MySQLPath.Text
        Else
            isMysqlPathCorrect = False
            MySQLPath.BackColor = Color.LightCoral
            StartMySQL.Enabled = False
            StopMySQL.Enabled = False
        End If
        If File.Exists((ApachePath.Text & "\httpd.exe")) Then
            isApachePathCorrect = True
            ApachePath.BackColor = Color.LightGreen
            StartApache.Enabled = True
            StopApache.Enabled = True
            apacheInfo.WorkingDirectory = ApachePath.Text
        Else
            isApachePathCorrect = False
            ApachePath.BackColor = Color.LightCoral
            StartApache.Enabled = False
            StopApache.Enabled = False
        End If
    End Sub

So what did i do to get the error, I selected the Folder (that has the AuthServer.exe and WorldServer.exe

(File.Exists((ServerPath.Text & "\authserver.exe")) AndAlso File.Exists((ServerPath.Text & "\worldserver.exe")))

Then its says: Line 13 & 14: Object reference not set to an instance of an object So how can i fix this if somebody can give tips or howto i be thankfull
