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

DestroyWindows should do the trick

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;

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,

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,
Bob

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.

Hi,

In a three pane splitter where the right pane is a CFormView, how can I calculate the width values for SetColumnInfo, so that the right pane is always at the exact width needed to accomodate it's dialog resource and resizing the window only affects the middle pane? (Kind of like the behavior of Outlook Calendar)

I've tried a lot of things, but I can't even get the initial sizes (before any resizing) right. The right pane is always either too small or too big or even just 0 width. And when I start meddling with the OnSize the whole thing goes completely crazy...

Anyone have a clue? (cause I can't seem to resize my brain to the exact size needed to accomodate the mfc documentation...)

Thanks.

Sure thing. Do you have five reams of paper ?

Get Visual Assist from www.wholetomato.com, type in WM_ and hit ALT-space - you'll get a list.

An easy way to see them all is to bring up the help (included with VC or the Platform SDK), go to the index, and type "WM_" and notice all the messages in the list. There is no single list of all the messages. They seem to broken out into different "sections", keyboard, mouse, etc.
