Okay, given you are new to forum, I looked.
Article in discussion seems to be:
Fast Colored TextBox for Syntax Highlighting[
^]
There are samples for it. Sample usage of autocomplete:
public partial class AutocompleteSample : Form
{
FastColoredTextBoxNS.AutocompleteMenu popupMenu;
public AutocompleteSample()
{
InitializeComponent();
popupMenu = new FastColoredTextBoxNS.AutocompleteMenu(fctb);
popupMenu.MinFragmentLength = 2;
var randomWords = new List<string>();
int codeA = Convert.ToInt32('a');
for (int i = 0; i < 26; i++)
for (int j = 0; j < 26; j++)
for (int k = 0; k < 26; k++)
for (int l = 0; l < 26; l++)
randomWords.Add(
new string(new char[]{Convert.ToChar(i + codeA), Convert.ToChar(j + codeA), Convert.ToChar(k + codeA), Convert.ToChar(l + codeA)}));
popupMenu.Items.SetAutocompleteItems(randomWords);
popupMenu.Items.MaximumSize = new System.Drawing.Size(200, 300);
popupMenu.Items.Width = 200;
}
private void fctb_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyData == (Keys.K | Keys.Control))
{
popupMenu.Show(true);
e.Handled = true;
}
}
}
There is a folder called 'tester' in one of the download attachment zip. It contains all the samples. Try out!
