Sounds like something from a Mutual Fund Prospectus

Can you be clear?What you really need?you want to have an rich edit control without any scroll bar. but it should contain any amount of data. as the data increases, instead of showing the scroll bar, your rcih edit control's size it self should increase?

what if your rich edit control's size goes beyond your dialog box's size as the data grows?sounds senseless...

thanks Johny, English was not my native language too; I thinks you have expressed what I mean. I just want to realize richedit control's size itself could increase automatically, no scroll bar; Of course, the data is certainly not infinite, but in a fixed area to increase the size of RichEdit. This matter is urgent need to address.
Who Can give me some suggestion.

The detail depends on the platform you develop with.

The simple concept is to react to some event the RichEdit control can send (typically, every time the user presses a key) and, after letting the default action to happen, monitor the state of the edited text (how long is it, how many lines it contains etc.), then try to guess if there is a "optimum size" to accommodate it, and consequently resize the Richedit control window accordingly (the richedit control is also a window, so it can be moved and resized like any other window).

Finding the optimum size is the difficult part, since the concept of "optimum" may be subjective. You have to decide if make the editor wider or higher, eventually changing the way lines are composed. The algoritm to di this can be anything trivial or very complex, but must be fast, since it has run in-line with the user typing actions.

The details can be found by googling "Ricedit control API" eventually followed by the name of the development platform you're using.

HI, I am Johny,
I am trying to elaborate his question. Please forgive me if I cannot do it properly.

In General when user continue writing and text grows longer than the window can hold. When the text is more than the window space RichEdit Control Display the Scroll bar. But Is there any way Where scroll bar of Richcontrol wont be visible and also It does not mean that RichEdit Control wont allow write more that it can hold.

Another thing: Probably OP also want to increase the height of RichContol with the increase of line. For this reason he want to know is there any message that says Richcontrol is running out Display Space?

English is not my native language either. I also have hard time to write something in English
