Re: Is there a "OnPaste(...)" - a CRichEdit question!

5-Jun-03 0:41

I have a rich-edit where I only want to support *one* font (Tahoma 10pt. etc.) set up at time of constructing of the edit. This works fine when writing in it.

But how do I force a text into this specific font and look when *pasted* in - from some other size and font?

Think it's something about monitoring the clipboard format but I'm not sure?

It makes sense to have a OnPaste() not calling the base impl. and then do the paste-work myself adding my format to it before it goes in - but no such are found anywhere!?

As far as I can see in CWnd I have:

ChangeClipboardChain(...)
SetClipboardViewer(...)
OpenClipboard(...)
GetClipboardOwner(...)
GetOpenClipboardWindow(...)
GetClipboardViewer(...)

and in CRichEdit:

Copy(...)
Cut(...)
Paste(...)
PasteSpecial(...)
CanPaste(...)

I'm a little puzzled here?

First, I am sorry, because I adviced yesterday to do so, and I did not answer your second post. :-OThere is actually no OnPaste() routine, do it that way :

Create a class CMyRichEditCtrl derived from CRichEditCtrl.
Create your RichEditCtrl in the resource editor, and assign it a control member : m_MyRichEdt

Go into the automatically generated code, and replace

CRichEditCtrl m_MyRichEdt;

with

CMyRichEditCtrl m_MyRichEdt;

Do not forget to add an #include "MyRichEditCtrl.h" in that same file after

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

Now override PreTranslatemessage like that :

B

OOL CMyRichEditCtrl::PreTranslateMessage(MSG* pMsg) 
{
	
	if ((pMsg->message == WM_PASTE))
	{
	    Change font ...
	}
	else
  	   return CRichEditCtrl::PreTranslateMessage(pMsg);
}

Hope this helps.

After few testing (sorry, no time today Frown | :(

), my code snippet lacks one or two things :

First, if (message == WM_PASTE) is not really good, since it can be that several messages are contained in one message. So prefer something like if ((message & WM_PASTE)==0) return ... else paste font;

Secondly, I think you will have to remove the WM_PASTE from the message queue, otherwise, the clipboard contents will be paste (it passes ans passes over again in PreTranslateMessage().

Found a better way - with some help!

5-Jun-03 11:57

OK thanx' - this is a new approch and I understand what you are saying. I'll check it out soon.

Only my feeling now is that this solution seems kind of "emergency exit" and a little primitive as well - there *must* be a better way. Not complaining or anything - Unsure | :~

Re: System Tray Problem...

Thanx' sharing the ideas!

But I found another way around my CHARFORMAT-problem than using the PreTranslateMessage(...) - here it is.

What I did was that I made the CHARFORMAT-change to the full selection in response to *not* an UPDATE event but a CHANGE ev. As it turned out an update-ev. came over and over again if I did the work on EN_UPDATE - ON_CHANGE was less sensitive. So this is how the final solution looks:

<br />
const void CCalFrameWnd::CCalendar::Note_EditChange()<br />
// Called from parent to signal that user are editing a note.<br />
{<br />
	TRACE(_T("Note_EditChange()\n"));<br />
	// Ensure usage of one charformat only.<br />
	long lChar_Start = 0, <br />
		 lChar_End = 0;<br />
	CHARFORMAT cf_def;<br />
	cf_def.cbSize = sizeof(CHARFORMAT);<br />
	m_pEdit_Note->GetDefaultCharFormat(cf_def);<br />
	m_pEdit_Note->GetSel(lChar_Start, lChar_End);<br />
	m_pEdit_Note->HideSelection(TRUE, FALSE);<br />
	m_pEdit_Note->SetSel(0, -1);<br />
	m_pEdit_Note->SetSelectionCharFormat(cf_def);<br />
	m_pEdit_Note->SetSel(lChar_End, lChar_End);<br />
	m_pEdit_Note->HideSelection(FALSE, FALSE);<br />
}<br />

So I just force the def-CHARFORMAT on to the entire selection having always set the def-format first. Also I remember to be able to restore to the orig. caret pos.

Btw. Can one make a "ON_EN_REFLECT_CHANGE" for a edit/rich edit - work like this should be held totally inside the class as far as I can se.

System Tray Problem...

Vladimir Georgiev4-Jun-03 22:23

I have problems with the message handler of a system tray icon. I am writing an SDI application, and it adds the icon with no problems, but my custom message handler does not get the messages sent to the icon.
I have successfully done this in a Dialog App some years ago, and now it does not work in the SDI one. I try to move this functionallity to the App, View, Frame classes - but nothing happens. I use VC++ 6.0 under Windows XP.
Are there any catches here? What do I do wrong???

Really appreciate the help.

All you need to do is create your own message MY_MSG (or something like that), then attach this message to the callbackmsg (of the trayicon), then place the message in the message map of your mainframe and implement the function you attached to the message.

I'v made a well working fct. for this:

inline const bool SetTrayIcon(
CWnd *pWnd,
CONST DWORD dwMessage,
CONST DWORD dwMessage_NIM,
CONST UINT uId_Icon,
LPCTSTR lpszTTT,
CONST UINT uId_Callback)
// In the tray, show specific icon. Return T on succes and F if not.
//
// To add the icon use: NIM_ADD for NIM msg.
// To change the icon use: NIM_MODIFY for NIM msg.
// To remove the icon use: NIM_ADD for NIM msg.
//
{
NOTIFYICONDATA nid;
nid.cbSize = sizeof(NOTIFYICONDATA);
nid.hWnd = pWnd->GetSafeHwnd();
nid.uID = uId_Callback;
nid.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP;
nid.uCallbackMessage = dwMessage;
nid.hIcon = (HICON)::AfxGetApp()->LoadIcon(uId_Icon);
::lstrcpyn(nid.szTip, lpszTTT, sizeof(nid.szTip));
bool bResult = (::Shell_NotifyIcon(dwMessage_NIM, &nid) != 0);
if(nid.hIcon)
::DestroyIcon(nid.hIcon);
return bResult;
}

And then you go:

BEGIN_MESSAGE_MAP(CMyFrameWnd, CFrameWnd)
// Callback handler for tray icon.
ON_MESSAGE(WM_NOTIFYICON, OnTrayIconNotification)
END_MESSAGE_MAP()

And:

LRESULT CCalFrameWnd::OnTrayIconNotification(WPARAM, LPARAM lParam)
// Called back on notifications to the tray icon.
{
switch(lParam)
{
case WM_LBUTTONDBLCLK:
{
// Do stuff.
break;
}
case WM_LBUTTONDOWN:
{
// Do stuff.
break;
}
case WM_RBUTTONDOWN:
{
// Do stuff.
break;
}

// etc.

}
return 0L;
}

...I forgot some examples:

// Setup tray icon.
::SetTrayIcon(this, WM_NOTIFYICON, NIM_ADD, m_uId_TrayIconActive, (LPCTSTR)GetBaloonInfo());

// Refresh baloon for tray icon.
::SetTrayIcon(this, WM_NOTIFYICON, NIM_MODIFY, m_uId_TrayIconActive, (LPCTSTR)GetBaloonInfo());

// Remove tray icon.
::SetTrayIcon(this, WM_NOTIFYICON, NIM_DELETE, m_uId_TrayIconActive);

And you have:

inline const bool
SetTrayIcon(
CWnd*,
CONST DWORD,
CONST DWORD,
CONST UINT,
LPCTSTR lpszTTTEx = _T(""),
CONST UINT uId_CallbackEx = 0);

Hai...
I need a Grid whcih should work like ExcelSheet..i.e at run time we should be able to add comments to text in a cell,sholud be able to insert a horizontal line in a cell...can anybody help me regarding this???

It's an extensive, capable grid, and it's free. Don't expect it to be an excelsheet-plug-and-play-replacement.

Like I said, it's a starting point. It is probably the best free grid code available. If you want more done for you, then you'll probably need to pay money.

It shouldn't be hard to add the cell commenting code to the grid source.

debug / release problem

well.. i wanted to put Chris Maunders Grid Ctrl with some Additions (some CellFormats) in a static lib.. everything works & compiles fine in debug mode..
but in release mode it always says:

<br />
Class.obj : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass const  CGridBtnCell::classCGridBtnCell" (?classCGridBtnCell@CGridBtnCell@@2UCRuntimeClass@@B)<br />

is there any possibility to turn the mfc runtime thingies on/off?

thanks in advance,

Make sure you compile both lib and application with "RTTI enabled" (Project Settings, C++, C++ Language)

well.. i've checked this, rebuilded everything.. and it still doesn't work..
the msdn says that this runtime - shista has got nothing to do with the c++ rtti, they made their own runtime - information (from cobject).. is there any way to disable / enable the mfc runtime - information?

thanks in advance...

:slaps forehead: Yep, sure, CRuntimeClass is the MFC version...
ugh, not much of ideas then Cry | :((

I guess the grid is relying on that.... check the MFC settings for the release build (static/dynamic). MSDN says:

Static linking to MFC is supported only in Visual C++ Professional and Enterprise Editions. For more information, seeVisual C++ Editions.

There seem to be quite some differences how MFC handles their own RTTI, depending on linking statically/dynamically to MSDN (and make sure the VCRT settings match those for MFC)
