Hi,
I have some problems regarding the version that MSDN gives and what my debug session returns to me!
I have installed WTL and the settings is set for WTL
What else is needed, there are things that just does not work as they should, for instance WM_NOTIFY
What is the correct settings to get WTL working in Visual studio that is?
I debug programs but they do not give me the answer that MSDN documentation says
Kindst regards Ulf

Can you use CDONTS.NewMail in a C++ program? I would certainly think you could, but I can't find any documentation for C++, just VB and ASP, etc. Can anyone point me towards a sample in C++ that instantiates a COM object and calls it? If you haven't already guessed, I'm new to C++.

You can use this class to send email. It's not CDONTS, but it works.

I am trying to calculate the elapsed time that occurs while a program in running. I need the time in milliseconds, can anyone help me.

Depending on how long your program runs, ::GetTickCount () should be good enough.
DWORD dwStart = ::GetTickCount ();
... do work ...
DWORD dwEnd = ::GetTickCount ();
printf ("Elapsed = %d", dwEnd - dwStart);
Now, if you program is only going to be running for a few seconds then GetTickCount might not be good enough. Then you have to use the miltimedia timers.

I have been trying to get the attributes from some XML all day!! Im slowly going mad! I have an XML file:-
//snip
<date name="12.12.3.98">12.56
//snip
I then have the following code. m_pCurrent is a node. I simply try and extract the attribute called name. Line 2 below works (unless i change the name of retrieval field - so I guess something is working) but when I try to access the value it just crashes with illegal access error... I have tried get_text, get_nodeValue etc etc.
m_pCurrent->get_attributes( &pNodeMap );
pScratchNode = pNodeMap->getNamedItem("name");
pScratchNode->get_text( &str );
AfxMessageBox( CString( str ) );
Thanks in advance

These are COM methods they return HRESULTs not interface pointers.
getNamedItem method takes two parameters.
From MSXML 4.0 documentation
C/C++ Syntax
HRESULT getNamedItem(
BSTR name,
IXMLDOMNode **namedItem);
Parameters
name [in]
The name of the attribute.
namedItem [out, retval]
An IXMLDOMNode object for the specified attribute. Returns Null
if the attribute node is not in this collection.

Hi! I am working on an application that requires the display of data graphically - ideally the same as in the AXE hex editor where one colour block represents one byte and a file can be shown as a panel. As a newbie, trying to navigate through the MFC documentation is a nightmare. Anyone able to assist please? If you're anywhere near Ireland, a solution is worth a number of pints of the black stuff!!

I have a COM server (A.exe) it supports two interfaces I1 and I2. I also have two services S1.exe and S2.exe. S1 creates and instance of I1 and S2 creates an instance of I2.
I expected to find only one A.exe running. Instead I find two. This is a problem for two reasons. S2 must release and recreate the interface regularly, causing the initialization of A.exe to happen way too often. The other issue is that I2 and I1 share a global array (protected by a MUTEX). This sharing clearly won't work if there are two separate eA.exes.
Is it possible to do this so only one A.exe is launched? If so, how?
We are supposed to release this today. The cyclic creation and destruction of a second A.exe was just observed for the first time today.
Thanks for the help,
Bill

Try this, it MAY solve your problem
Add this BEFORE the COM_MAP of your Interface
DECLARE_CLASSFACTORY_SINGLETON(CYourI1InterfaceClass)
- Greatest invention : "The Microchip!"

I tried it, but it didn't help. I think its because there are two apps accessing two different interfaces, rather than two apps accessing the same interface.
Next attempt is to use CoGetClassObject. MSDN says:
"Provides a pointer to an interface on a class object associated with a specified CLSID. CoGetClassObject locates, and if necessary, dynamically loads the executable code required to do this."
Sounds like it won't load the EXE if it's already there. This coincides with VB and GetObject versus CreateObject.
Unfortunately I get an error AND the wrong effect:
hr = CoGetClassObject(ID, CLSCTX_LOCAL_SERVER, NULL,
IID_IDispatch, (void **)&(m_pBroker));
if(hr = S_OK)
{
g_pErrorLog->LogError(4,"Get Class succeeded " + strObjName,_strModule);
} else {
hr = CoCreateInstance(ID, NULL, CLSCTX_LOCAL_SERVER,
IID_IDispatch, (void **)&(m_pBroker));
g_pErrorLog->LogError(4,"Try to CoCreate",_strModule);
}
When it executes the CoGetClassObject call, I get an ERROR_NO_INTERFACE message 0x80004002. AND a second .EXE is loaded. 
Thanks for the help,
Bill

If you use ATL, Check CComModule::RegisterClassObject call. In your WinMain function , _Module.RegisterClassObject. Check the second parameter - is REGCLS_SINGLEUSE ? If is so , the class factory will be accesible only for one client at a time.

Have you considered using the GIT or ROT? Singleton won't work because S1 and S2 are seperate processes any data in A won't be shared.

Ah, testing.

Solon's suggestion put me on the right track. There are 3 modes in which to register:
REGCLS_SINGLEUSE (obvously wrong)
REGCLS_MULTIUSE (I ghought this one would work for me)
REGCLS_MULTI_SEPARATE (Its THIS ONE!!)
This is the one to use if you want multiple clients to share the same instance of the server. The use of the word SEPARATE fooled me into not realizing that if I wanted them to use the same server, I should use the SEPARATE option.  lol.
Thanks for the help,
Bill

I would like to automate Outlook Express for a dialog app in VC++ 6.0/.NET? I have found code for Outlook 2000 but I have it but hate it and this program will only be on my computer.
Thank you.

POP& BuyAPop(Money ADollar){...};

Unfortunately, Outlook Express cannot be automated. However, if all you want to do is automate the process of sending and receiving e-mails then there are many classes here at the CodeProject which might act as a starting point.

Is it possible to add/set a transparent colour to a bitmap in a dialog bar?
.NET or not .NET? MFC is the question......

Watcha Folks,
I’m trying to find a way to monitor socket connections on a local machine, in particular to know how many sockets are open, and which ports their assigned to (even better would be to know which application is using which socket!). Does anyone have any idea how I can accomplish this??  Or if its even possible?

Have you tried netstat ( netstat.exe ) ?

I have been trying to terminate a thread I started in my application. I am writing a server application and have spun a seperate thread off for the server, that in turns spawns another thread when a client connects, and I am using Winsock 2.2. During the listen portion of the server thread I put it in a while loop more specifically:
while(1)
{
}
However, I get a memory leak when I quit the application, since it is in a while loop the thread can not properly terminate. I have tried several methods in order to get it to terminate. Here is what I have tried:
In my ThreadParam struct I added a variable bool Stop. When I start the thread I set stop to false and in the while loop I use an if statement to check for Stop. If it is true I break out of the while loop so the thread can close safely. I change Stop to true in the WM_CLOSE message of the MAIN GUI interface--No success.
Tried using a loop in the close function to make sure that the thread has stopped by checking the return value of ::GetExitCodeThread and making sure it doesn't return STILL_ACTIVE--No success
Current thoughts:
Even though this is a worker thread as defined by MFC I'm thinking of turning it into a UI thread so I can use PostQuitMessage and send a user defined message to thread to terminate.
Any suggestions to resolving this matter? Thanks in advance for any help.
