  I'm just at the start of learning VB.Net using VB 2008 Express. I'm trying to understand things as I go along but have come across something that I can't grasp.

  There are two examples that I am trying to learn at the moment: one for Write and one for WriteLine. But when I check the contents to the text file with the Write example I always get the text preceded by System.Windows.Forms.TextBox, Text: but I just get the text that I'm expecting with the WriteLine example. I just don't understand why. Please help me to understand.

  Write Example

  Dim FILE_NAME As String = "C:\test.txt"

  If System.IO.File.Exists(FILE_NAME) = True Then

  Dim objWriter As New System.IO.StreamWriter(FILE_NAME)

  objWriter.Write(TextBox1)

  objWriter.Close()

  MsgBox("Text written to file")

  Else

  MsgBox("File Does Not Exist")

  End If

   

  WriteLine Example

  Dim FILE_NAME As String = "C:\test.txt"

  Dim i As Integer

  Dim aryText(4) As String

  aryText(0) = "Mary WriteLine"

  aryText(1) = "Had"

  aryText(2) = "A"

  aryText(3) = "Little"

  aryText(4) = "One"

  Dim objWriter As New System.IO.StreamWriter(FILE_NAME)For i = 0 To 4

  objWriter.WriteLine(aryText(i))

  Next

  objWriter.Close()

  [quote]objWriter.Write(TextBox1)[/quote]

  should be: objWriter.Write(TextBox1.Text) .. since I assume you're wanting the write the text that's actually displayed in the TextBox object, as oppossed to the simply wrting out the actual string 'value' of the TextBox object itself.

  Thanks. I did understand it then. It's just that I couldn't see the .Text missing right under my nose and of course the program was just working as instructed.

  No problemo. Think we've all done that at some point.
