Ok, so I was following a guide on how to make a syntax highlighting RichTextBox for a new editor that I'm making, but I'm having a problem with base.WndProc
protected override void WndProc(ref System.Windows.Forms.Message m)
{
// Code courtesy of Mark Mihevc
// sometimes we want to eat the paint message so we don't have to see all the
// flicker from when we select the text to change the color.
if (m.Msg == 0x00f)
{
if (paint)
base.WndProc(ref m);
else
m.Result = IntPtr.Zero;
}
else
base.WndProc(ref m);
}
At the end of the check message statement, I get a stack overflow exception with this:
m = {msg=0x441 (EM_STREAMOUT) hwnd=0x280a8a wparam=0x8011 lparam=0x64e67a0 result=0x0}
m.Msg = 1098
this = {Text = The runtime refused to evaluate the expression at this time}
In the main form, I have this:
private void Box_SelectionChanged(object sender, EventArgs e)
{
SyntaxTextBox box = (SyntaxTextBox)sender;
int idx = box.GetLineFromCharIndex(box.SelectionStart);
int start = box.SelectionStart;
int len = box.SelectionLength;
string line = box.Lines[idx];
Regex r = new Regex(@"[0-9]+", RegexOptions.IgnoreCase|RegexOptions.Compiled);
SyntaxTextBox.paint = false;
foreach (Match m in r.Matches(line))
{
box.Select(m.Index, m.Value.Length);
box.SelectionColor = Color.Blue;
box.SelectionStart = start;
box.SelectionColor = Color.Black;
}
Console.WriteLine(start);
SyntaxTextBox.paint = true;
}
What's going on with my code?
