D3DXFONT_DESC not being set

[Elixir42]

Hi I can't seem to adjust the D3DXFONT_DESC properties. Sometimes it breaks at getDesc(...). I want to be able
to have each text row have their own font description and be able to change it. Why is it not working???

Maybe I setting it in the wrong place or maybe it is not being 'set'. (See ::Add)

My great thanks to you who solves it!!!

Here is the class header and implementation:
CText.h

    int  Add(char* cText);

    void SetRow(int iRow, char* cText);

    LPD3DXFONT GetFont(void);
    void SetItalic(bool bItalic);

    void Draw(void);
    void DrawTable(void);


private:

    LPD3DXFONT  m_DXFontMaster;   // pointer to the font object

    RECT        m_TextBoxMaster;        // rect to contain the text

It's not supposed to work like that.

You have to create the font again, replacing the old one.

So call CText::Create() with an italic parameter.

Thanks yet again dx9_programmer I have cleaned up the code and call a createcustom function. Each time i want to add I alter a saved font description then use that with the create function.
