Yeah, true. After raeding a couple of articles by Joe Newcomer I have always tried to avoid GetDlgItem and UpdateData in my code, specially being a big fan of Joe, that I am.
A lot of people seem to forget that we can use class wizard to create control variables for our dialog controls. I mean most people would have associated CStrings with text boxes but how many associate an edit box with a CEdit?

It was Paul DeLascia who pointed it out to me, in an MSJ article.

I almost *always* associate with a control, not a variable. Then I can roll my own data validation, which is always better than the rubbish MFC comes out with.

I use GetDlgItem and UpdateData all over my code for too many years. I haven't read Joe's writings on why they're bad. Can you briefly tell me the problem?
I guess it's habit - it's how I was shown a long time ago. It appears to work well though. Is it considered bad style now?
thx

Hi Guys,
i am creating an app with a doc/view architecture. The base class of my view class is CListView. Now i am using the InsertColumn function of CListCtrl. After that i am inserting some strings with the InsertItem function. The problem now us that i am changing the font, and the font of the Column also changes. WHY ?? I want that the Column Font stay always same and only the inserted String font wwould be changed...
Please see code:
void CFVCtrlView::OnInitialUpdate()
{
CListView::OnInitialUpdate();
CListCtrl &lCtrl=GetListCtrl();
lCtrl.InsertColumn(0,"Header",LVCFMT_LEFT,300);
lCtrl.ModifyStyle(0, LVS_SORTASCENDING | LVS_REPORT | LVS_EX_FULLROWSELECT );
lCtrl.SetBkColor(RGB(160, 184, 207));
}
.
.
.
void CFVCtrlView::SetFonts()
{
CListCtrl &lCtrl=GetListCtrl();
CFont *font=(CFont *)this;
font->CreatePointFont(100,"arial");
lCtrl.SetFont(font);
lCtrl.InsertItem(1,"Hello World",0);
}
Please help if anybody can...
Its really urgent.

It's really obvious when you think about it - you've set the font for the list control, so the list control uses that font.
I don't know of any way to fix this apart from making the list owner drawn and storing a font, or font details, for each cell that doesn't use the standard font of the control as a whole. That doesn't mean there *isn't* another way, I've never tried to do what you're doing.
Chris's grid control in a form view may provide the answer, I'm not sure if it does per cell fonts or not.

How can I change the title caption of a dialog (CDialog) object?
I want to do the following:
CSetupDlg::OnShowSummary()
{
CString sMyTitle;
CSummaryDlg dlg;
// Somehow, set the title of the Summary Dialog
// with sMyTitle, today's date, or "The Summary is..."
dlg.doModal(); // I might use modeless case - must work both ways.
}
Thanks all!

SetWindowText on the dialog.

If I pass in the "text" I want to use, I have no problem:
CEntitySummaryDlg::OnInitDialog()
{
SetWindowText(m_captionText); // m_captionText initialized in constructor.
// blah, blah, ...
}
However, I wanted to set the caption text before the call to DoModal() in my calling routine. I guess this is not possible as CEntitySummaryDlg dlg has yet to be created.
Thanks, I think I can work with this.

That's correct - you'd need to make a variable in the class, set it before creation, and use that variable to set the text in OnInitDialog.

Here's a general solution to performing dialog initialization when using modal/modeless dialogs.
- Put your initialization code in a member function, eg: CMyDialog::initialize().
- Add a command handler macro for a custom command (eg: WM_USER + 1), which executes initialize().
- In your dialog's OnInitDialog(), post a WM_COMMAND with WPARAM = (WM_USER + 1).

I must be missing something - how is this better than just calling the function, or putting the code in OnInitDialog ? I understand that posting the message causes it to occur after the init message is processed, but the usual thing is to call the base method *first* so that the dialog is initialised.

If you subclass controls, the initialization can fail in the case of modeless dialogs, since the controls' windows aren't always created when a modeless dialog's OnInitDialog() executes. Hence the deferred initialization.
The problem doesn't exist with modal dialogs, but because there's no harm in deferring initialization for modal dialogs, the same method (no pun intended) can be used.

I have overriden the OnEraseBkgrd function of CStatic
also postcreatewindow and drawitem are overriden, this is for the control of my static text box so i can draw directly to the box.
I would like to know how to update the box, after OnPaint does not call the OneraseBkgrd function which is where the drawing code is contained. I'm wondering if i could send a windows message with WindowProc(WM_ERASEBKGND,1918,0); could u tell me if this is the best way to update the box's content as i think it may update the entire window.
Actually that doesnt want to work... Please Help!;)

just call Cstatic::Invalidat(true);

|
|

Mmmm... if your static is on a dialog, have a look at the docs for CDialog::OnCtlColor. Might be able to do some work there if its called.
If pWnd->GetDlgCtrlID() shows up as the id of your static, you're set.
