RichEdit Control problem

Hi,

I want to set up document into my richedit box, but it does not like as I want.

From begin:
I've create document into microsoft word. Document have cells and looks like I want. Now I've wrote it as RTF document (formatted). Now to test it I opened it into wordpad. It looks like too.
Write as anoter name into wordpad created 2x smaller document :) but still looked as OK into wordpad and microsoft word.

Now I've create resource file with dialog and richeditbox:
CONTROL "Rich Edit", IDC_RICHEDIT1, RICHEDIT_CLASS, WS_TABSTOP | WS_HSCROLL | WS_VSCROLL | WS_BORDER | ES_CENTER | ES_AUTOHSCROLL | ES_AUTOVSCROLL | ES_MULTILINE | ES_READONLY, 7, 7, 455, 229

Now I read RTF text, allocate memory, replace some elements into text and send to control:
SETTEXTEX sx;
sx.flags = ST_DEFAULT;
sx.codepage = CP_ACP;
SendMessage(hDlg,EM_SETTEXTEX,(WPARAM)&sx,(LPARAM)data);

Where data contains RTF text. Dislplayed data was diffrient as expected. Looks like text leaves the cells. I don't know how I can change it.
When I same "data" after modyfication to file and open into word/worpad then looks like I want.

I've found similar problem this: http://bytes.com/groups/net-c/244588-richtextbox-tables
