Has anyone every done anything with Active Directory Notification. I need to write a service that listens to LDAP and lets me know when things change such password changes, etc. I found the sample code on MSDN (http://msdn.microsoft.com/library/default.asp?url=/library/en-us/netdir/ad/example_code_for_receiving_change_notifications.asp), however I'm unable to get the code to compile. I seem to be missing all of the header files.
-Any thoughts?
Thanks

I have used the select(); function in an attempt to program a [Timed out] message into my program. In this case the host I am working with is www.ebay.com. You will notice that if you open a command prompt in windows and ping www.ebay.com that you will get four [timed out] output messages sent to the screen. I would like to do the same thing with my program and have chosen to use the select(); function to accomplish this task. The problem is that select(); returns the socket connected to www.ebay.com as readable. How could this be? If I can't use select(); to discover that I have not gotten a reply, how then will I know that no echo reply has been sent back to me?
Thank you,
Eric Sepich

Remember that a ping is performed at a lower level (ICMP) than a normal socket using select (TCP). Probably the reason you get no response by pinging www.ebay.com, is that the server is not responding to ping requests, and yet does respond to TCP requests (it would have to in order to serve HTTP!). Hence your select returns that it has connected.

Hi all,
I have an extention dll that export a dialog.
and i have an *.exe client that uses the dll and that dialog.
when even the mouse is over the dialog i want to play a wav here is the code i am using:
void CMyDlg::OnMouseMove(UINT nFlags, CPoint point)
{
HINSTANCE hInstance = AfxGetResourceHandle();
PlaySound(MAKEINTRESOURCE(IDR_BTN_CLICK),
hInstance,
SND_RESOURCE);
CDialog::OnMouseMove(nFlags, point);
}
the sound wav file is at the dll resources.....
the trouble is when look in debug mode at the value of hInstance, i see it points to the exe and not to the dll therefore the wav is not played....
how can i switch the resource???
i know there is a method called AfxSetResourceHandle()
but i don't know what to pass to it????
please help
thanks in advanced

Use AFX_MANAGE_STATE(AfxGetStaticModuleState()) at the beginning of the offending functions in your extension DLL. This macro takes care of setting and restoring the resource handle.

Hi, thanks for the reply
I've tried that already, and i got a compilation error:
mfcs42d.lib(dllmodul.obj) : error LNK2005: __pRawDllMain already defined in GUILib.obj
mfcs42d.lib(dllmodul.obj) : error LNK2005: _DllMain@12 already defined in GUILib.obj

mfcs42d.lib(dllmodul.obj) : warning LNK4006: __pRawDllMain already defined in GUILib.obj; second definition ignored
remember i am using an extention dll and not regular one.....
can u still help?
thanks again

Yes, you're right. Try with AFX_MANAGE_STATE(AfxGetAppModuleState()) instead (and please tell us back )

thanks for the reply,
now it compiles. but the following code returns me the resource handle of the exe and not the dll:
AFX_MANAGE_STATE(AfxGetAppModuleState());
HINSTANCE hInstance = AfxGetResourceHandle();
PlaySound(MAKEINTRESOURCE(IDR_BTN_OVER),
hInstance,
SND_RESOURCE);
hInstance is 400000 which is the exe (should be 100000 for the dll)
can u help again?
thanks

Ummm... I'm shooting in the dark here. Try replacing your hInstance stuff with
HINSTANCE hInstance = AfxGetAppModuleState()->m_hCurrentInstanceHandle;

Here I go again OK, I have not tried this, but I'm more or less confident it'll work. In your generated xxx.cpp where the DllMain function is defined, there is a static AFX_EXTENSION_MODULE object. Remove the static bit and declare it as extern in some header file, so that you can use it elsewhere. The hResource member of this AFX_EXTENSION_MODULE is what you need to pass to AfxSetResourceHandle. Remove the AFX_MANAGE_STATE stuff, it's not needed. Don't forget to restore the original resource handle upon exiting. Shake well and serve chilled. Good luck.

i did that, and got compilation error regarding the extern AFX_EXTENSION_MODULE already defined????
can u help?

Can you show the relevant code regarding the AFX_EXTENSION_MODULE both in the header and the .cpp file? Thanx

In the header:
extern AFX_EXTENSION_MODULE GUILibDLL; In the .cpp where your DLLMain is:
AFX_EXTENSION_MODULE GUILibDLL = { NULL, NULL };Please tell me if this works. If so, I'd feel a little guilty that you might have applied tihs blindly without clearly understanding what's going on. Please consult some C++ tutorial or book on the meaning and use of extern and static.

thanks.
now the dll compiles ok, but the client that uses the dll show me error on the method (that i showed you before):
void CMyBtn::OnLButtonDown(UINT nFlags, CPoint point) <br />
{<br />
CButton::OnLButtonDown(nFlags, point);<br />
<br />
======> AfxSetResourceHandle(GUILibDLL.hResource);<br />
<br />
HINSTANCE hInstance = AfxGetResourceHandle();<br />
PlaySound(MAKEINTRESOURCE(IDR_BTN_OVER),<br />
hInstance,<br />
SND_RESOURCE);<br />
<br />
AfxSetResourceHandle(AfxGetResourceHandle());<br />
}
it says:
"error C2065: 'GUILibDLL' : undeclared identifier"
where else should i define it in the dll beside dllmain file????
thanks again

I don't get it. How could the client fail in a function compiled inside the DLL?

With regards to:
---> bReadible = !(nStatus == 0);
What does this mean? I have never seen code written like this before.
BOOL CRawPingDlg::IsSocketReadible(SOCKET socket, DWORD dwTimeout, BOOL& bReadible)
{
timeval timeout;
timeout.tv_sec = dwTimeout / 1000;
timeout.tv_usec = (dwTimeout % 1000) * 1000;
fd_set fds;
FD_ZERO(&fds);
FD_SET(socket, &fds);
int nStatus = select(0, &fds, NULL, NULL, &timeout);
if (nStatus == SOCKET_ERROR)
return FALSE;
else
{
bReadible = !(nStatus == 0);
return TRUE;
}
}
Thank you

The ! means NOT.
If you have a boolean value like true the operator ! will make it to false.
if nStatus has the value zero, the term wil be true. !(nStatus == 0) will make it false. It is the same if you write nStatus != 0.

The ! negates the statement. if (nStatus == 0) is TRUE, then the ! negates it and bReadible will be FALSE.

Hiya I am trying to use a C# dll from my MFC program. But am having a big problem.
To use the C# dll, I have changed the compiler settings in my MFC program to - Use Managed Extensions and have included #using <mscorlib.dll>.
But as soon as I change to use managed extensions, my program will not run.
I am using .Net Framework Ver 1.1
Am I doing something wrong or is there another way??
Thanks.

As most of you know, I have been trying to do WYSIWYG printing from a CRichEditCtrl. The problems I was having was that the font bring printed was either too big or too small for the perscribed area.
OK, here is some what of a solution (except it isn't bullet proof!)
I create a device context to the display (while printing and in print preview), create the font scaled to the display and scaled to the printer. I then get the size of the line for each. I then calculate the scaling factor by getting the pixels in the X axis for both and dividing. For the printer here at work, it is 1200DPI, and the screen is 96DPI. This factor works out to be 12.5.
I then take the text width on the screen and multiply it by this ratio to
get an ideal output width. Divide the printer width by the ideal width that gives a ratio. I then get the average character width (from
GetTextMetrics - Printer). I then multiply this value with the ration from the ideal vs. actual printer. Then set this value in the LOGFONT.lfWidth and create a new font and select it into the printer device context.
As an example:
The width of text on the display is 410 pixels, this same string on the
printer (with no change in the character width) is 5352. The scaling factor of 12.5 means that the ideal lenght is 5112.5 pixels. The division of the Printer/Ideal = 1.066146. The average character width for the printer (with selected font) is 80 pixels. So, divide the 80 / 1.066... and the new character width is 75.
I read in Petzold's book that the lfWidth of the LOGFONT can be set to the tmAvgCharWidth from the TEXTMETRIC structure. AND, that it can be scaled.
The resulting output for the TIMES NEW ROMAN 12/10pt and COURIER NEW 12/10pt are right on (with the exception of a rounding error of a pixel). I do this for each line.
Now the caveat! When I use Arial Normal, the last line which isn't as long as the rest, and this creates an average character width is bigger than the previous lines.
I think there is something in the TrueType specification that can help with this. Does anyone know? If so, what?
