The ITAddress::CreateCall method creates the ITBasicCallControl interface.
HRESULT CreateCall(
BSTR pDestAddress,
long lAddressType,
long lMediaTypes,
ITBasicCallControl** ppCall
);

Using the Windows CColorDialog class, is it possible to select any of the custom colors that one saves? I am populating the custom colors before calling the DoModal class and the colors appear correctly. However, calling SetColor only seems to select the square that is in the basic color boxes. Is selecting a custom color programmatically possible?

Under MS-DOS, you used get_vect() and set_vect() to install an ISR to handle interrupts; for instance, if you used IRQ 10 for the PC-104 bus.
How do you do the same thing in WIN32? How do you get a hardware interrupt to call a function that you supply?

Hardware and interrupt handling under Win32 (specifically, Windows NT/2000/XP) is vastly different from MS-DOS and even Windows 3.x/9x.
User applications do not handle interrupts. Period. The best you can do is have a driver signal an event, and have a thread in a user application wait on that event. At that, the user application can't manipulate hardware directly (I/O instructions are prohibited to user applications).
You need to get a copy of the Windows Driver Development Kit (DDK). If you are using off-the-shelf hardware, contact the manufacturer for application programming information. Usually, if it's something special (data acquisition H/W, for example), they will provide the appropriate driver and an object library or interface DLL to talk to the hardware. If this is hardware you (or your company) are building yourself, you will need to learn driver development, which is distinctly non-trivial.

Aahhh, interrupts. I remember them  (nostalgic look on face).
Its surprising how coding in the windows environment can completely change your concepts of programming.

Hi gurus,
I'm working on a ATL plug-in for MS Outlook, but I would like to make it work on Outlook Express as well. I understand that it's not possilble via COM technology (as OE does not expose any COM interfaces  ), but something with hooks? Any documentation on the subject?
Any help / hint would be much appreciated.
Thanks in advance,
Doru K.

On http://www.elitesecurity.org/tema/8207/0#61676 you can find attached file "Office2000-add-in.tgz - 20.71k" on bottom of some message with useful information to you. I realy did not work with Outlook but I realize from message its right thing what you asked.

Thank you for your answer, but unfortunatelly, I couldn't find what you directed me to, because of language impediments. Thank you anyway.

Hi,
following situation:
Class A owns an array of Class B variables.
Class B owns a variable of Class C.
Class C runs as a thread which is started by Class B.
What I want to do: when thread C ends, I want Class A to remove B from the array.
What I tried: B knows whom it is owned (knows the A) and C knows the B. So when C ends, it can call a function in A to tell it to remove B.
However this is a quite bad solution. Because the function can't really complete (it can't jump back into C because it has then been destroyes). It just not seems to work.
How can I code this clean?
Thanks a lot!
Chris

Perhaps C could remove its entry from A's array of class B variables just before it terminated?

I have the following code in my program
data.GetErrorFlag == CVerifyData::InvalidData When this code executes I get two errors on it, they are as follows, Error 1: "error C2446: '==' : no conversion from 'const long' to 'long (__thiscall CVerifyData::*)(void)'", with extra info stating "There are no conversions from integral values to pointer-to-member values". Error 2: "error C2040: '==' : 'long (__thiscall CVerifyData::*)(void)' differs in levels of indirection from 'const long'" data is a variable of type CVerifyData. The GetErrorFlag function returns a value of tye LONG and CVerifyData::InvalidData is a static member variable defined in the class header/implementatoin files as
static const LONG InvalidData;
const LONG InvalidData = 0; Could anyone give me some help on why I'm getting this error. I don't really understand what it's saying. Thanks.

I have an exe. i have several COMs (0 or more) which are Dlls.
all COMs have the same one and only interface called IMgr and co-class CMgr.
in this interface there is a method called 'GetModuleDlg' which does something
all the COM-Dlls are located under the subdirectory 'Dlls'
I use the 'LoadTypeLib' and GetTypeInfoCount and GetTypeInfo
to connect to the COM-Dlls. i need to mention, i don't have the *.tlb files and all the connection is done dynamically in run-time not in compilation time.
my question is this : all i have to do is to "CreateInstance" of the COM dll, and then invoke "GetModuleDlg"....can any1 show me code on how to do that using the ITypeLib and ITypeInfo interfaces???
I've searched CP, CG and google, but i found poor examples regarding....
thanks in advanced

I need to define an array of CMenu's. But I really dont now how many I need, I only know this at runtime.
I cant do this... CMenu menu[myvariable];
Because it needs a constant.
When I use CMenu *menu = new CMenu[myvariable];
The program crashes when I try to access a member function of CMenu. Like, menu[0]->AppendMenu[...];
Can I not use CMenu[variable] at all? Is there no workarounds?
BTW, I dont know why it crashes when I use pointers to CMenu.
Thanks!
Daniel

You could use a dynamic collection (eg: CPtrArray).

Forget what I first typed, it was plain wrong. However, it seems probable that your array of CMenu items needs to be initialised in some way.
Or you could use a vector, or list, depending on the metrics of how you will use the collection.

You have to initialize each CMenu in the array via a call to CreateMenu(), something like this:
CMenu *menu_array = new CMenu[myvariable];
for (int i = 0; i < myvariable; i++) {
menu_array[i].CreateMenu();
}
