Hi,
I'm developing an app that uses a RichTextBox, and populates it with
colour formatted text at Form Load. However, I randomly receive this
error, which I believe is related to this data population:
Unhandled Exception: System.NullReferenceException: Object reference
not set to an instance of an object.
at System.Windows.Forms.RichTextBox.EditStreamProc(In tPtr dwCookie,
IntPtr buf, Int32 cb, Int32& transferred)

wndProc, IntPtr hWnd, Int32 msg, IntPtr wParam, IntPtr lParam)

hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
at System.Windows.Forms.UnsafeNativeMethods.PeekMessa ge(MSG& msg,
IntPtr hwnd, Int32 msgMin, Int32 msgMax, Int32 remove)
Does anyone have any insight into this? I've googled to no avail so
far.
TIA
