(smack forehead) DOH! Much better than my recommended way. An add-in or macro would be the best way to do it. Nice suggestion!

Do you mean :

int num = 3; /* get user input and assign to num */

 if(num == 5)
#define _A
#undef _B
 { }
 else
#define _B
#undef _A
 { }

#if defined(_A)
 cout << "_A defined.\n";
#endif

#if defined(_B)
 cout << "_B defined.\n";
#endif

The result is :

_B defined.

WlxSetTimeout

Has anyone tried using this function? It wants seconds for the new timeout value but everything I throw at it fails. Or I should say returns "0", which is supposed to be failed. I even tried the default value of 120 without luck.

It does seem to do something to the timeout - makes it about 5 minutes regardeless of what value I set.

I'm testing on W2K Workstation Professional SP2.

Thanks,
David

There are seveal registry classes on CodeProject. Do they not do what you need?

I have been exploring this for hours. The one by PJ Naughter seems the most promising but I haven't been able to figure out how to get it to update any of the keys except the one he wrote for his company. What he wrote looks great. I'm just struggling because I can't get it to work for me. The problem is me and that is why I asked for help.

I have a much simpler CRegistry class that has always worked for me. If you want, I'll send it to you.

OnDraw in composite control ??

I want to overwrite the OnDraw of my ATL composite control, to prevent flickering when redrawing. I thought I could just overwrite the CComCompositeControl::OnDraw, but it seems this method is never called, instead the OnPaint of CAxHostWindow is called, which does not call the OnDraw as the OnPaint of the CCompositeControl does.
Anyone got an idea how to do this ???

Killing the in-place edit

Eugene Pustovoyt2-May-02 4:21

2-May-02 4:21

Hello,

I have a little question!
I have a CEdit-derive class, we shall tell CMyEdit.
Inside it on pressing the left button of the mouse I create in-place edit, we shall name CInPlaceEdit

pEdit = new <code>CInPlaceEdit</code>;
pEdit->Create(WS_CHILD | WS_VISIBLE | ES_CENTER, rect, this, 100);

Then, when CInPlaceEdit loses focus, it needs to be removed.

Where and as it is better to remove him!?

Best regards,

Eugene Pustovoyt

If I have correctly understood, I should in CInPlaceEdit in method OnKillFocus call DestroyWindow?
This same that in the parent to specify delete pEdit?

Or in DestrowWindow it is necessary to specify

delete this;

Best regards,

Eugene Pustovoyt

If you look at the CWnd d'tor, you'll see that it calls DestroyWindow for you (shown here) so you can do the "delete this" if you want and it will work.

// wincore.cpp
CWnd:: ~CWnd()
{
 if (m_hWnd != NULL &&
  this != (CWnd*)&wndTop && this != (CWnd*)&wndBottom &&
  this != (CWnd*)&wndTopMost && this != (CWnd*)&wndNoTopMost)
 {
  TRACE(traceAppMsg, 0, _T("Warning: calling DestroyWindow in CWnd:: ~CWnd; ")
   _T("OnDestroy or PostNcDestroy in derived class will not be called.\n"));
  DestroyWindow();
 }

 ...
}

Thank you!

But I have some more questions, there can be you help to me, before I shall create a new theme!?

1. Why in-place edit I can't change the background color?

CInPlaceEdit::OnCtlColor()
{
   HBRUSH hbr = (HBRUSH)m_brColorBk;
   pDC->SetColorBk(m_crColorBk);

   return hbr;
}

2. How to delete in-place edit, when the mouse clicked outside the parent window?

Best regards,

Eugene Pustovoyt

1) You're handling the wrong message. You need the following:

.h file

afx_msg HBRUSH CtlColor(CDC* pDC, UINT nCtlColor);

.cpp file

BEGIN_MESSAGE_MAP(CMyEdit, CEdit)
  ON_WM_CTLCOLOR_REFLECT()
END_MESSAGE_MAP()
...
HBRUSH CMyEdit::CtlColor(CDC* pDC, UINT nCtlColor)
{
  pDC->SetBkColor(RGB(255,0,0));   
  return m_Brush;
}

2) Do the "delete this" in the control class' OnKillFocus

I have a dialog that uses the 8 point Sans Sarif font. I want to make a static text control have a larger & bold font. How do I change the font for this one control on my dialog?

Thanks in advance,

In this thread, I list a complete code snippet on cycyling through all controls on an edit control and setting their fonts.

You can easily modify this to set all the static controls or just a single static control. Let me know if you need any help with either.
