I've got a multiline textbox that I'm using to display messages. Is there an
easy way to have it scroll to the end after I add a line to the text of the
box?

The only way I've found, is to use Windows messages ... Not nice but the only
solution I ever found.
using System.Runtime. InteropServices ;
[DllImport("user 32.dll", EntryPoint="Sen dMessageA")]
static extern uint SendMessage(Sys tem.IntPtr hwnd, uint wMsg, uint wParam, uint
lParam);
const int WM_VSCROLL = 0x115;
const int SB_BOTTOM = 7;
TextBox report ;
void printError(stri ng msg)
{
...
// auto scroll to bottom of text control
SendMessage( this.report.Han dle, WM_VSCROLL, SB_BOTTOM, 0);
}

Jeff,
Here's a very simple technique that works with a RichTextBox; should
work with a regular TextBox also:
RichTextBox.Sel ect(RichTextBox .TextLength, 0);
RichTextBox.Scr ollToCaret();
Hope this helps,

hello,
I'm afraid that not the right solution.
Before found the solution with Windows Message, it was the first thing I've used.
But it does not work it the control has not got focus. Hope this helps, John Bendiksen

Cyrille37,
Not sure why it didn't work for you...
In my 'process control' type application, I am updating 4 RichTextBoxes
continuously with status information (probably similar to Jeff's
situation). None of them ever have focus; in fact, they are not even
selectable by the user. They all scroll properly to the last added
text using this technique.
Happy coding,
John Bendiksen

Set HideSelection to false.

I am struggling with a problem for sometimes. I need to display a table in

I searched high and low for an answer on how to auto scroll a

posting to anyone who might have similar concerns. For the record
this works well in an environment where you cannot have focus going to
the richtextbox....such as a chat...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
