I'm looking for a "CScrollWnd" version of CScrollView -- basically one that I can derive from without requiring the document/view architecture. Is there such a beast?

If not, is there a good tutorial somewhere for doing all of the scroll stuff (proper tracking sizes, etc?). I'm making a custom control and it's been a quite while since I've had to do this.

Thanks in advance!

You can create a CWnd with the WS_HSCROLL and WS_VSCROLL style.

learn all you can from MSDN's pages on scrollbars.

one instance of dialog box

dear all,
i have an mfc dlg based app which adds an icon in the taskbar, which on dbl clicking shows up a dialog box.

this dialog box is not the main window of my app.

the main window is a frame which is hidden (m_pMainWnd= CFrameObj) and this frame is also associated with the taskbar icon.

the problem is every time i dbl click on the icon, a new dialog box appears but i want only one dialog at a time

how do i go 'bout it?

I use a static variable:

static HWND s_hWnd = 0; //window handle of this dialog

// Create new dialog
int CMyDialog::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{
	if(s_hWnd) { //window is allready opened?
		::SetForegroundWindow(s_hWnd);
		return -1;
	}
	
	if(CDialog::OnCreate(lpCreateStruct)==-1) 
		return -1;
	s_hWnd = m_hWnd	//store handle
	
	return 0;
}
void CMyDialog::OnDestroy() 
{
	if(s_hWnd==m_hWnd) s_hWnd = 0; //reset window handle of this dialog
	CDialog::OnDestroy();
}

No. Your client would need to have Office installed on their computer, if you were using Office components in your code. At least that's what the last licence agreement I read for Office Developer said.

Microsoft used to have Viewer applications for all these file types. Have a look on the office web-site. I know I downloaded a Powerpoint viewer a little while back.

fro win98, you need to use the unicows libraries.

CRectTracker inside CScrollView

Anonymous22-Dec-02 18:29

22-Dec-02 18:29

I wrote a program that one could choose items from a toolbar and put them on the document by clicking left
button of mouse on the view. I considered a CRectTracker variable for each symbol and in the OnDraw function I
draw each symbol's tracker's rectangle.And for selecting each symbol which is shown on the page I check if the
position of left click of mouse is in the tracker of any of the symbols or not.
At the beginning I used CView class but now I want to use CScrollView in order that my program could support scrolling.I changed the base class of my view class to CScrollView and write some lines in its OnInitialUpdate in order to set the size of scrolling.Even I changed coordinates with CDC::DPtoLP function.
Now I scroll my program but when I put an item on the page and scroll the page , in some places that my item doesn't
exist , it seems that its tracker exists .

Thanks

In the dialog editor, press Ctrl+D to set the tab order. Each control will have a number by it, just click the controls to set their new order. (ie, the first thing you click will be #1, the next thing #2, and so on)

Need help using object in ATL ActiveX EXE window services server.

22-Dec-02 17:43

hi,

I'm developing ATL ActiveX EXE server that runs as a Window services using ATL wizard.
This server contains one ATL object (CTest).
How I can set the server so that when it started (via Window Services Applet), the server will :

1) initiate/create CTest.
2) Call method/function in this ATL object (CallMe).
3) destroy CTest when server stopped.

Thanx in advance.

Regards.
