CLabelControl problem

[manju 3]

Hi all, Cant we hide a CLabelControl after declaring a variable..??? I am getting a run time error for this.

Test.h
CLabelControl m_Test;

Test.cpp
DDX_Control(pDX, IDC_LABEL_TEST, m_Test);

BOOL CExampleDlg::OnInitDialog()
{
CLabelControl* lTest;
lTest=(CLabelControl*)GetDlgItem(IDC_LABEL_TEST);
lTest->ShowWindow(SW_HIDE);
return true;
}

If i comment
//CLabelControl m_Test; in Test.h
//DDX_Control(pDX, IDC_LABEL_TEST, m_Test); in Test.pp

Then it runs without any error.

Can anyone have any idea Thanks in Advance Sharan

Your label control does not exist at the point you are trying to hide it. You need to call CDialog::OnInitDialog in your OnInitDialog method before the control exists.

BOOL CExampleDlg::OnInitDialog()
{
CDialog::OnInitDialog();
CLabelControl* lTest;
lTest=(CLabelControl*)GetDlgItem(IDC_LABEL_TEST);
lTest->ShowWindow(SW_HIDE);
return true;
}

Hope that helps.
