Which slider is active in dialog?

Oliver12322-Sep-06 11:10

How do I determine which CSlider is sending a message?
1. Dialog CExoSliderDlg with two sliders and two edit boxes.
2. Both sliders work, and both deliver nPos which is used to update edit box variable m_SliderValue.
3. I want IDC_SLIDER to update m_SliderValue
4. I want IDC_SLIDER2 to update m_SliderValue2.
5. I think CScrollBar* pScrollBar can tell me which slider is active.
6. I don't know how to determine which slider is active. How to do it?

IDC_SLIDER_VALUE CString m_SliderValue
IDC_SLIDER_VALUE2 CString m_SliderValue2
IDC_SLIDER CSliderCtrl m_Slider
IDC_SLIDER2 CSliderCtrl m_Slider2

void CExoSliderDlg::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
if(nSBCode == SB_THUMBPOSITION)
{
m_SliderValue.Format("%ld", nPos);
UpdateData(false);
}
else
{
CDialog::OnHScroll(nSBCode, nPos, pScrollBar);
}
}

This is correct.

Use CEdit instead of CString. Update the edit controls using SetWindowText().

OK. But the fog still lingers a bit.

But how do I determine which slider is active? How do I use CScroll* pScrollBar to determine which of the two sliders is sending the message?

I feel like the answer is right in front of me, but I just can't grab it.

Thanks

I found some code that I adapted to my application. It works. It allows me to determine which of the two sliders is active, and then set the appropriate edit box to the value generated by the slider. I don't follow the reinterpret_cast<csliderctrl *="">, but it works. Here is the resulting function. (The @ are not in the code. The @ should be replaced by brackets formed with < and >, but I can't get this editor to accept them.):

void CExoSliderDlg::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
int iActiveSlider = 0;
CSliderCtrl *Slider, *Slider2;

// Identify the sliders of the dialog box using their IDentifiers
Slider = reinterpret_cast@CSliderCtrl *@(GetDlgItem(IDC_SLIDER));
Slider2 = reinterpret_cast@CSliderCtrl *@(GetDlgItem(IDC_SLIDER2));

if( reinterpret_cast@CSliderCtrl *@(pScrollBar) == Slider )
{
iActiveSlider = 1;
}

if( reinterpret_cast@CSliderCtrl *@(pScrollBar) == Slider2 )
{
iActiveSlider = 2;
}

if(nSBCode == SB_THUMBPOSITION)
{
if (iActiveSlider ==1)
{
m_SliderValue.Format("%ld", nPos);
UpdateData(false);
}

if (iActiveSlider ==2)
{
m_SliderValue2.Format("%ld", nPos);
UpdateData(false);
}
}
else
{
CDialog::OnHScroll(nSBCode, nPos, pScrollBar);
}
}

Using the same resource editor that you used to create the dialog and the menu.

List controls use the LVM_SCROLL message not WM_HSCROLL and WM_VSCROLL.

what is the use of "&" here

look at "dc.SelectObject(&pen)" and "dc.SelectObject (&brush)",here no matter I use "&" or not it results the same. why is that?

[code]
void CMainWindow::OnPaint ()
{
CPaintDC dc (this);
CBrush brush (RGB (255, 0, 0));
CPen pen (PS_NULL, 0, (RGB (0, 0, 0)));

dc.SelectObject(&pen);
dc.SelectObject (&brush);
dc.Ellipse (0, 0, 200, 100);
}

Because CGdiObject, which is what CPen and CBrush are derived from, has a HGDIOBJ() operator. Control eventually goes to CDC::SelectObject(HGDIOBJ hObject). When a pointer is passed instead, control goes right to CDC::SelectObject(CPen* pPen).

Mail Merge with HTML

Hi All,
I have an application developed using VC++. This application uses mail merge for word 2003. This application opens a word document and a xls file for data source. Does anyone have a sample code that does a mail merge??..

Thanks,
Bharani

The mail merge code that I have uses HTML file as data source. The mail merge object opens the data source using the function call shown below:

mailmergeobj.OpenDataSource(
strFilename,
(LPVARIANT)COleVariant( CString("html")),
&vtFalse,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional,
covOptional);

mailmergeobj.Execute(covOptional);

When this code is executed it comes up with a popup for "Select Table". Can someone tell me how to suppress this popup??

Thanks
Bharni
