  Hi All,

  I get this error operator == cannot be applied to operands of type 'System.IntPtr' and 'int'

  firstly I had this code

  private void SNGPH_KeyUp(object sender, KeyEventArgs e) {

          if (e.KeyCode != Keys.ControlKey)
              return;
  
          POINT curpos = new POINT();
          User32.GetCursorPos(ref curpos);
          IntPtr handle = User32.WindowFromPoint(curpos);
          handle = User32.GetAncestor(handle, 2);
  
          for (int i = 0; i < listBoxTables.Items.Count; i++)
              if (((PokerTable)listBoxTables.Items[i]).HWND == handle)
              {
                  listBoxTables.SelectedIndex = i;
                  setFormsAndDoCalc(true, null);
                  e.Handled = true;
                  return;
              }
  
          pictureBox1.Image = SystemIcons.Error.ToBitmap();
          labelWarning.Text = "Couldn't find selected window from pokertables";
      }
  

  which is fine when you click control key over a table it then finds the table in the list (listboxtable) and executes it. Now I tried to make this into every foreground window to do the same thing and show handle in text bar.

  Heres the code I get an error with

  private void GetActiveWindow() { const int nChars = 256; int handle = 0; StringBuilder Buff = new StringBuilder(nChars); handle = GetForegroundWindow();

          if (GetWindowText(handle, Buff, nChars) > 0)
          {
              this.textBox1.Text = handle.ToString();
  
              for (int i = 0; i < listBoxTables.Items.Count; i++)
              if (((PokerTable)listBoxTables.Items[i]).HWND == handle)
              {
                  listBoxTables.SelectedIndex = i;
                  setFormsAndDoCalc(true, null);
                  return;
              }
  
          }
      }
  

  Can anyone please help, not sure whats wrong the handle im sure is an int in both cases?

  Thanks in advance!!
