Through googling I later found that the easiest way was to use the GetGuiResources method in User32.dll. This provides the GDI and USER objects counters for each process.

Yeah, it looks promising. I'll give it a try on Monday. Have a nice weekend.

Embarrassingly enough I believe the out-of-memory was due to that I dodn't took care of when there was no hit on the search. The failed to load resources probelm remains though.

Embarrisingly enough I tried that first but discrded as not working. Just to find out that the control needed focus before it worked... So it was just to add richTextBox1.Focus(); richTextBox1.ScrollToCaret();

Thanks for your answer but unfortunately I have no control of the logfile. It's because it's huge and diifcult to read I'd like to build my own logfile reader. What I need most I think is a tip on how to reverse output using StringBuilder. Otherwise I do thing StringBuilder is the way to go.

Well, I was advised to use the webbrowser COM component and that was it.

Dunno what I was thinking about yesterday since it was pretty obvious. private void onLoad(object sender, System.EventArgs e) { richTextBox1.Text = "Hello World\n"; richTextBox1.AppendText("This is the string I search for\n"); richTextBox1.AppendText("Another Hello World Again\n"); } private void button1_Click(object sender, System.EventArgs e) { int loc = richTextBox1.Find("string"); int linePos= richTextBox1.GetLineFromCharIndex(loc); int lineLen = richTextBox1.Lines[linePos].Length; int lineStart = richTextBox1.Lines[linePos].IndexOf("string"); richTextBox1.Select(lineStart,lineLen); richTextBox1.SelectionColor = Color.Blue; richTextBox1.SelectedText = richTextBox1.Lines[linePos]; richTextBox1.AppendText("strPos: " + loc + ", Len: " + lineLen + ", linestart: " + lineStart); }

here are a few possible adjustments you can make to your code. string reader stuff blah blah blah while ((input=sr.RealLine()) != null) { if (input.StartsWith("2")) { myList.Add(input); } } sr.Close(); richTextBox1.Clear(); System.Text.StringBuilder data = new StringBuilder(myList.Count*avgLen); for (int i=myList.Count; i>=0; i--) { msg.Append(myList[i]); msg.Append(System.Environment.NewLine); } richTextBox1.Text = msg.ToString(); ______________________________ The Tao gave birth to machine language.

Try it - it doesnt. Yes SetDlgItemText changes the text - though really its the Win32 way of doing things. The way he has done it with UpdateData basically calls SetDlgItemText anyway under the hood - just using the DDX/DDV map to work out what to map to what. But just like UpdateData, SetDlgItemText will set the text after the loop has returned. If you are processing a message spinning in a loop then no other messages will come through when you are doing that (specifically, WM_PAINT's) until you return from that loop. Hence, yes u have changed the text in the edit box with SetDlgItemText but the edit box wont redraw until your function returns.
