Re: Scrolling in CFormView

Hi Friends,

Thanks in advance.

I have an SDI application in which view is derived from CFormView
i.e

<b>class CquestionnaireView : public CFormView</b>

Now i have a menu option "add question" ; on click the menu option a
dialog is created in the form view i.e.

<b>void CquestionnaireView::OnOptionAddquestion()
{

     // Dailog class
     CQuestionDlg* pQuestionDlg = new CQuestionDlg(GetItemCount);

pQuestionDlg->Create(IDD_DLG_QUESTION, this);

// vector of dialogs
       m_vecQuestionsDlg.push_back(pQuestionDlg);

// get the height
       int nWidth = 0, nHeight = 0;// set sroll view size
for( UINT x = 0; x &lt; m_vecQuestionsDlg.size(); ++x )
{
CRect rtQuestionDlg;
m_vecQuestionsDlg[x]-&gt;GetClientRect(rtQuestionDlg);

nHeight += rtQuestionDlg.Height();
}

CRect rtClient;
GetClientRect(rtClient);
// set scroll sizes
       SetScrollSizes(MM_TEXT, CSize(rtClient.Width(), nHeight));

// reposition the dialog
       pQuestionDlg->RepositionWindow();
}</b>

its location is ok; till i dont do verticle scrolling as I do verticle
scrolling and Add new dialog; dialog is not visible but it holds the
position in View.

Please tell me do I need to handle verticle scroll bar; if yes then
how to do it.

////////////// Repostion window code

<b>void CQuestionDlg::RepositionWindow(UINT nFlags)
{
      int x, y; // width, height;
CRect rtClient, rtParent;
GetWindowRect(rtClient);
int nWidth = rtClient.Width();
int nHeight = rtClient.Height();

GetParent()-&gt;GetClientRect(rtParent);

/////// m_nIndex -------- is the dialog insert location i.e. 0, 1,
2... so on
       x = 0;
       y = 0 + m_nIndex* nHeight;

CRect rect(x, y, x + nWidth, y + nHeight);
SetWindowPos(NULL, rect.left, rect.top, rect.Width(), rect.Height(),
nFlags);

}</b>

Thanks,
