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,

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

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.

right aligning the right pane in a splitter

2-May-02 2:21

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.

Run the Spy++ application that ships with VC++. When it starts, select the Log Messages menu item, drag and drop the Finder Tool icon onto a window and then click the Messages tab. At that point, you will see the roughly 1000+ messages you can capture. You can also filter these messages (via type) so that you can spy on specific messages types (e.g., keyboard, mouse, afx/mfc, edit control, etc.)

Yes, it's just a standard API call, so you can use this library from any language that supports API calls.

Hmmm, interesting... Unsure | :~

Why do people use MFC for server applications, and why go through all the trouble of creating/debugging a thread-pool when we have IO Completion Ports... (Yea, I know they only works under NT) Wink | ;)

using structure in different files

I have the following struct:

typedef struct IPHWNDTAB
{
HWND hWnd;
char IP[30];
}IPHANDLE;
typedef IPHANDLE FAR IpHandle[5];

I want to use the var "IpHandle" in different files in my visual c++ project. some of the files are *.c files that create a dll and some are *.cpp files which are com interface files.

what is the best way to implement this so that I can use this "IpHandle" from different files in my project?

thanks,
Aviv.

Declare it as extern in stdafx.h, and declare it in stdafx.h.

You can either declare it globally as the first posted proposed or you can make it a public member variable of the application class.
