thanks stewart it worked nice! but i have another problem : my language is right to left when i send message to justify text align the richtextbox RightToLeft property becomes to RightToLeft.NO but it's first value was RightToLeft.Yes! and setting that again to RightToLeft.Yes does not affect the text! it only works properly when RightToLeft property value is RightToLeft.No! what can i do? how can i have deep study on native and managed data types and marshalling? do i need special resources to do this study? best wishes
