Programmatic changes to Doc data

I have a document with CEditView that I want to limit to 80 characters. i was thinking of adding a check where I update the row/column counter. However I'm not sure how I can insert a "\r\n" at that point in the document.

Any help? or better ways I can approach this.

Thanks a bundle.

We have a software development project which includes 74 PC's with in it a PlexWriter 24/10/40A.

Our program has to be able to write to CDR. Due to other reasons we cannot use Packet writing. Is there a programmers Interface (API) to a CDR/CDRW ?

I know your OS is Windows 2000/SP2, but if you can afford a Windows XP upgrade, you can use IMAPI, a high-level API for CDR/CDRW writing. And it will work on whichever writer/interface Windows can recognise.

No, but there are free source available to do what you want. Google for e.g. CDRecord.

Scroll bar question - need experts help here

Hi,

i am trying to disable the horizontal scroll bar in list ctrl. the scroll doesn't appear until i add a lot of items in the list (it appears because the vertical scroll bar appears as well).

here is the code i use
void CMyListCtrl::OnStyleChanging(int nStyleType,LPSTYLESTRUCT lpStyleStruct)
{
if (nStyleType != GWL_STYLE)
{
CListCtrl::OnStyleChanging(nStyleType,lpStyleStr
uct);
return;
}

lpStyleStruct->styleNew &= ~WS_HSCROLL;

SetWindowLong(m_hWnd,GWL_STYLE,lpStyleStruct->styleNew);
}

this indeed change the style of the list not to have WS_HSCROLL bar, but the scroll bar is still shown....

please help me
i am really desperate, this is the 4th post i am asking for help

thanks
Yaron

Are you trying to remove the scrollbar so it doesn't even appear when normally it would, or are you just trying to disable it so that it's shown but the user can't scroll with it?

Unfortunately, there is no easy answer. Scrollbars in CListCtrl are drawn and handled internally by the list control, and aren't actually controls by themselves. Thus the only way to disable them is to derive from CListCtrl and write your own drawing routine... not a very fun thing to do.

What's the cause of the scroll bar appearing in the first place? If you're trying to forcefully remove it, have you looked at fixing what causes it to appear?

I had the same issue. What I ended by doing is resizing the columns when the vertical scroll is added. So instead of hardcoding the width of column, you assign it a percentage of the listctrl's width. Then call this function whenever your listctrl needs a vertical slider. The user can still resize the column with the header control (which could cause a horizontal scrollbar to appear).

void CMyDialogDlg::ResizeColumns(const int iPercentageOfListCtrl)
{
	CRect rect;
	m_cListCtrl.GetClientRect(rect);
	int iNewWidth = (rect.right * iPercentageOfListCtrl / 100);
	int iOldWidth = m_cListCtrl.GetColumnWidth(0);
	if (iOldWidth != iNewWidth) {
		m_cListCtrl.SetColumnWidth(0, iNewWidth);	// resize the first column
	}
}

This will resize the first column enough so that the list ctrl doesn't think it needs a horizontal scroll bar.

Hope this helps.

well presumably the user can select an area of the view to print somehow ... when they select print u would figure out what part of the data they have selected in ur document and send that to the printer

Cancelling a long process

Hello everyone,

Wow. It's been a while since I've been here. I was doing some embedded stuff there for a while. It's nice to be back.

Anyway, the question that I had has to do with having the ability to cancel a process that is in the middle of a for() loop. What I would like is a dialog that pops up on the over the application window that simply says "Cancel". I was reading used the code from Nishant's article Tutorial - Modeless Dialogs with MFC (http://www.codeproject.com/dialog/gettingmodeless.asp#xx211427xx). I've declared my modeless dialog as a local variable in the function with the loop. In the loop I want to check to see if the Cancel button was pressed. When I enter my loop, I can't press the Cancel button. Any ideas?? Thanks in advance.

LONG CTest3431::TestKeypad()<br />
{<br />
    LONG lRetVal = 0;<br />
    CCancelDlg dlgCancel;<br />
<br />
    dlgCancel.SetProgressText("Running keypad test...");<br />
    dlgCancel.ShowWindow(SW_SHOW);<br />
    ....<br />
<br />
    for( i=0; i<sizeof(sbKeys); i++ )<br />
    {<br />
        if( dlgCancel.IsOperationCancelled() )<br />
        {<br />
            lRetVal = -1;<br />
            break;<br />
        }<br />
        <br />
        ....<br />
     }<br />
<br />

Hi guys.
I have the following question?

I know that the WM_CHAR message goes to the main window of the program but isn't it Main Frame?Yeah,yeah ... i see that this is CView but where exactly this is coded in MFC?

And if I try to "go round" Doc/View and do something like
m_pMainWnd = new CMainFrame
m_pMainWnd->ShowWindow(..)
m_PMainWnd->UpdateWindow()

who gets WM_CHAR ?

and yes .. .I'm a newbie Smile | :)

template and ptr to it...

Stan the man21-Oct-02 3:41

Stan the man

21-Oct-02 3:41

OK. I made a template class that is like a circular buffer but then that could take many diffferent types of variables for a 2-D type graph.

Now, I want to use declare a pointer to this in another class BUT that does not know what kind of variables it will be before hand. Is this possible? After this, when I declare the graph class lets say, I want to tell it what kind of variables the circ buffer will be. This way, it can use the variable types and how I tell it to plot or do some manuipulation.

I am not sure how even to do this. Any ideas would be greatly appreciated.

Thanks
