[C#] 투명배경 RichTextBox

배경이 투명한 리치텍스트박스(RichTextBox) 입니다.

메신저 대화창 작업중 투명한 넘이 필요해지는 바람에...

public class TransparentRichTextBox : System.Windows.Forms.RichTextBox
{
      public TransparentRichTextBox()
      {
        	base.ScrollBars = System.Windows.Forms.RichTextBoxScrollBars.Vertical;
      }

      [System.Runtime.InteropServices.DllImport("kernel32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
      public static extern IntPtr LoadLibrary(string lpFileName);

      protected override System.Windows.Forms.CreateParams CreateParams
      {
            get
            {
                  System.Windows.Forms.CreateParams prams = base.CreateParams;
                  if (LoadLibrary("msftedit.dll") != IntPtr.Zero)
                  {
                      prams.ExStyle |= 0x020; // 투명설정
                  }
                  return prams;
            }
      }

      override protected void OnPaintBackground(System.Windows.Forms.PaintEventArgs e)
      {
      }
}
