"Object required" (When add variable)

[hoainam85]

Hi,

In VC++ 2005, when I add a variable to a dialog (m_slider for a slider control in that dialog), the class wizard always returned me "Object required", without any other informations.

Could anyone please help me for this problem? It's driving me nut!

Thanks in advanced.

So you may prefer to assing a variable by writing a line, like that:

 
CSliderCtrl* pSlider = (CSliderCtrl*) GetDlgItem(IDC_SLIDER1);

When you add the variable, do you have the control highlighted when you click on the 'Add variable...' menu item?

You can also add a CSliderCtrl member variable manually to the class, and then in DoDataExchange add this:

void CYourDlg::DoDataExchange(CDataExchange* pDX)
{
   CDialog::DoDataExchange(pDX);

   DDX_Control(pDX, IDC_SLIDER_ID, &m_slider);
}

That's exactly what VS is doing for you.
