Text In TextBox Visible

[Gary.Lowe]

Hi Everybody!

Does anyone know how to add text to a text box and when it reaches the bottom of the text box it automatically scrolls to the active line.

I have an application that imports numerous text files.

It adds a line in a text box to show what it has imported from each text file.

Your mission if you chose to accept:
If there are a lot to import and the text reaches the bottom of the text box it disappears. I want the text box to scroll down so the current line is allways in view.


Thanks in advance.

You could base your code on this sort of thing...

Private Sub Command1_Click()

Text1 = Text1 & Now() & vbCrLf

Text1.SelStart = GetLastVBCRLF(Text1)

End Sub

Private Function GetLastVBCRLF(strIN As String) As Long

Dim i As Long
Dim char As String
For i = Len(strIN) To 1 Step -1
  char = Mid(strIN, i, 2)
  If char = vbCrLf Then
  Exit For
  End If
  
Next i
GetLastVBCRLF = i


End Function

Gazza,

Try this:

Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" _
    (ByVal hwnd As Long, _
    ByVal wMsg As Long, _
    ByVal wParam As Long, _
    lParam As Any) _
As Long

Public Const EM_GETLINECOUNT = &HBA

Public Const EM_LINESCROLL = &HB6

Private Sub Text1_Change()

    Dim lCount&, lRes&
    
    lCount = SendMessage(ByVal Text1.hwnd, ByVal EM_GETLINECOUNT, 0, 0)
     If lCount >= 10 Then ' or any value you like
        lRes = SendMessage(ByVal Text1.hwnd, ByVal EM_LINESCROLL, 0, 1)
     End If

End Sub
