[CONNECT C++] Text/properties/formatting

Hi,

I used "textblock" created a string of text. I found out that the text length and width are zero (from text property/formatting).

I used following code.

		TextBlockPropertiesPtr tbProps = TextBlockProperties::Create(*ISessionMgr::GetActiveDgnModelP());
		ParagraphPropertiesPtr paraProps = ParagraphProperties::Create(*ISessionMgr::GetActiveDgnModelP());
		RunPropertiesPtr runProps = RunProperties::Create(*DgnTextStyle::GetActive(), *ISessionMgr::GetActiveDgnModelP());
		tbProps->SetIsViewIndependent(true);
		paraProps->SetJustification(TextElementJustification::LeftBaseline);

		runProps->SetColor(Color);
		runProps->SetFontSize(fontSize);
		runProps->SetFont(*pDGNFont);
		TextBlockPtr textBlock = TextBlock::Create(*tbProps, *paraProps, *runProps, *ISessionMgr::GetActiveDgnModelP());

......
            textBlock->SetUserOrigin(Point);
            textBlock->SetOrientation(Matrix);
            textBlock->AppendText(WTxtString);
	.....		

How can I set the text width and height.

Thanks,
