I've got the following prototype:
afx_msg void OnPvcsCtxtEditfile(HTREEITEM hNodeIn = NULL);
However, calling the function from my context menu, I get a bogus value for hNodeIn.
It has a NULL value if I call the function from elsewhere without an argument, but I guess when its called via messaging a value gets set along with it.
Is there anyway I can keep this from happening without adding a function to handle the context menu message that simply recalls the real one?
Thanks

You can add another default parameter,
bool bCalledFromSomewhereElse = true
And then when you post the message, post with false, and handle it accordingly.

Unfortunately as the afx_msg type functions are used through MACRO's and function pointers that have to conform to a prototype you can't define a default value for them. I am surprised you don;t get a horible crash with what you have. Looks like you will have to do it in 2 stages.

It crashes inside the function, when I try to access that tree item.

I am getting the following error in afxconv.h:
c:\program files\microsoft visual studio\vc98\mfc\include\afxconv.h(22) : error C2146: syntax error : missing ';' before identifier 'AfxDevModeA2W'
c:\program files\microsoft visual studio\vc98\mfc\include\afxconv.h(22) : fatal error C1004: unexpected end of file found
The error is here:
#ifdef _WINGDI_
LPDEVMODEW AFXAPI AfxDevModeA2W(LPDEVMODEW lpDevModeW, LPDEVMODEA lpDevModeA);
LPDEVMODEA AFXAPI AfxDevModeW2A(LPDEVMODEA lpDevModeA, LPDEVMODEW lpDevModeW);

LPTEXTMETRICA AFXAPI AfxTextMetricW2A(LPTEXTMETRICA lptmA, LPTEXTMETRICW lptmW);
I am usinf MFC in a shared DLL with a console app. I have MFC working with CString and all that fun stuff. The problem arises when I #include <afxtempl.h>.
If it's any help, I am trying to integrate CMarkup with my program. The demo project compiles and works fine.
Any advice will help!
Thx!

Take alook at the file which is including the header, you may be missing the ; there.

IT WAS THE LOCATION OF THE Markup.h HEADER FILE!!!!!!!!
I put Markup.cpp and Markup.h in a subdirectory called "xml".
I added the path to my project settings, and it didn't complain. After 4 hours of this, I thought... "lets try to move the files up a directory"
Is it time to go home yet?!?!?!?!!?

My app is a non-MFC .exe file (it opens a dialog box and then do stuff...) and i would like it to act as an activex component for IE.
I've created a CLSID and stored the correct info in the registry. It seems to work fine except for one thing: when the app is downloaded on the first time, everything works fine. But after that, when the app is run from the previoulsy downloaded version, the app launches correctly but IE seems to freeze for about 30 seconds.
Anyone has an idea where this comes from ?

Hy,
I ported a small application from Visual C++ 6 to .NET and now on some computers it crashes when it shows a "Save" dialog.
The problem is that i've tried it on about 10 computers and only on 2 of them crashed, on the others works perfectly.
The OS on the "crash" comptuer is NT4 with Service Pack 6.
I was wondering if anybody knows what's happening or heard of similar situations. I've heard of similar problems, but don't know any real answer, so any help is really welcomed.
Thanx in advance.

OK. I have an application icon that is 32x32 pixels and has 16 million color depth. I open the icon in Visual Studio 6 (and .NET) and it doesn't look correct. I understand that Visual Studio can't edit high color icons, however I need to have these icons displayed on the caption bar of a dialog based application, as well as in a ListView. I tried using LoadIcon to display this correctly and it doesn't work.
By the way, I am trying to displayt his high color icon transparently. The icon in the caption bar has an orange background when its supposed to be transparent. Apparently the LoadIcon only works with 256 color icon images.
Anyone have any suggestions?

Did you look here[^]?
That may help.

I saw this, but I don't think it will help with the caption bar of a dialog based application. I thought Windows XP handled drawing these icons automatically, and would dither them down to the right image if that size/bit depth was not present in the .ico file.
Is there a standard MFC call that will set the icon for the application like the SetIcon call in MFC?

Don't use LoadIcon(). LoadIcon() is a hold-over from the 16 color 32x32 Win3.1 days. Use LoadImage().
Also, unless you have rather large title bars, you may wish to use a 16x16 icon. If the 32x32 image is used in the listview, then keep that too. Once again, LoadImage() is smarter about this.
Finally, keep in mind that 24bit color icons occasionally cause problems on systems prior to WinXP - 256 colors are usually enough for such a small image, and work on all versions.

Is there away for me to create a function with the same name and the program calls my API instead of the windows API.
Thanks

I don't think this would be very good practice. Put your similar function in a seperate namespace and access it that way.
i.e.:
instead of the program calling:
::OpenFile(lpFN,lpOpBuf,uStyle);
You would call:
YourNamespace::OpenFile(lpFN,lpOpBuf,uStyle);

Hi,
to make a socket closed gracefully, I set the SO_LINGER on and call shutdown() before closesocket(). But the MSDN said The shutdown function does not block regardless of the SO_LINGER setting on the socket.
does it mean no unsent data will be sent when shutdown() with SD_SEND flag?
Thanks.

My version of MSDN reads for shutdown:
If the how parameter is SD_SEND, subsequent calls to the send function are disallowed. For TCP sockets, a FIN will be sent after all data is sent and acknowledged by the receiver.
To me this says that every send call that has succeeded up to this point is indeed transmitted to the destination.
What even more confirms this is a later section reading:
To assure that all data is sent and received on a connected socket before it is closed, an application should use shutdown to close connection before calling closesocket.
The fact that the call does not block might simply mean it's asynchronous.

My COM component needs to do some blocking operation, so i implement this operaion as a separate worker thread inside component. Now when operation completes, i want to fire event from the control. But i don't want my worker thread to fire this event. Instead i want my COM's primary thread to fire it. Is it possible ?? How can worker thread communicate with COM's primary thread ???

If your main thread gets blocked until the worker thread finishes, then I don't see the point of the worker thread. Just put it all on the same thread.
As far as ways of communicating, here's one: create an Event (see CreateEvent or CEvent)in the main thread and pass it to the worker thread. When it's finished, have it signal the event (SetEvent). In the mean time the main thread will be blocked until the event is signaled (WaitForSingleObject). Once that occurs, it will know that it's time to fire the control's event.

Alvaro

Hello All!
I have a class derived from CView with a public variable defined like a CListBox m_listbox.
When I try to create this listbox dynamicaly in runtime in ON_COMMAND like :
m_listbox.Create(WS_CHILD|....,CRect(0,0,0,0),this,LDC_LIST)
I recieved an erorr,although build was ok. I recieve an error even befor I come inside of Create
when I override Create(..).
When I declare listbox like local variable in method it is passes Create(..) without any problem but ofcource not shown.
This algorithm was working when I create this Listbox dynamicaly in class derived from Richedit.
Parameter for Create (dwFlags, CRect, CWnd*, ID) but and Richedit and CView were derived from CWnd.
So where can be a problem? I couldnt find any solution all last night  ...
Thanks for help

Just a guess, but is the value of LDC_LIST already used by a different control?

Thanks. No, I have already check this.. And in this way why it was working with local variable..

Can you post all the code that does a call to create, the overridden Create function (if you have one) and the declaration of the variable as well. That may help us spot the problem.

So:
*------SampleView.h
CSampleView::CView
public:
CAB4LisBox m_listbox;
*------SampleView.cpp
ON_COMMAND(ID_AUTOCOMPLETE, OnAutocomplete)
void SampleView::OnAutocomplete()
{
.......
if(!m_listbox.hWnd)
m_listbox.Create(CRect(0,0,0,0), this);
}
Where :
bool CAB4LisBox::Create (CRect rect, CWnd* pParentWnd)
{
dwFlags = WS_CHILD|WS_OWNERDRAW|HAS_STRINGS.....; <---- Here Breakpoint => not stop
return CListBox::Create(dwFlags,rect,pParentWnd,IDC_LIST); error befor.
}
In case :
void SampleView::OnAutocomplete()
{
.......
CAB4LisBox m_listbox;
if(!m_listbox.hWnd)
m_listbox.Create(CRect(0,0,0,0), this);
}
working->Have entered into Create,breakpoit works, but list not dispalyed.
Sorry for not full coding, I havent it with me now, so wrote as remember.
