In my experience ATL is the one you really need for COM or ActiveX. I've not used (or got) V2008 Express so can't really comment on what you can do with it. In theory you may be able to do without the AtiveX Wizard but it could require a lot of painstaking work on your part, though in saying that I'm assuming your Express version supplies all the header files and so on you would need if you took that approach.

Thanks a lot. Yes, I've got all the headers and libs that needed to build ATL/WTL projects, what I want to know is how to set up a project quickly... If there is no convenient way to auto generate an ActiveX project, I'm afraid I have to do this painstaking work...

As has been said earlier, ActiveX is really an ATL thing.

Yes, but this article is talking about to host ActiveX controls rather than make ActiveX controls by WTL. Poke tongue | ;-P

As the article intro says:

"Since ActiveX controls are ATL's specialty, there are no additional WTL classes involved"

This really applies wether you're hosting ActiveX or building ActiveX.

Certainly. Because WTL is an extension on ATL.

COM DLL Registration

Hi all,

Greetings and Salutations!!

I have a problem registering COM DLL's. I use ATL to create COM components but the rgs files which ATL creates and the registration process of ATL seems to only register the DLL with HKEY_LOCAL_MACHINE. If I want to register the DLL using a Windows Guest user, it does not seem to register it. Now, I looked at skype and skype seems to install on both guest accounts and admin accounts. Ofcourse, Skype does use COM DLLs but it seems that the trick is to register the DLL within HKEY_CURRENT_USER. This seems to work for skype so why shouldn't it work for me? Ofcourse, the installation would only be available to the guest user but I am ok with that. My question is, can I just make changes to the rgs file and register the DLL with HKEY_CURRENT_USER or do I have to write routines of my own which makes entries in the registry? In short, is there any way other than writing your own code which can be used to register my COM DLL with HKEY_CURRENT_USER??

Thank You for your time.

I now seem to be able to update the rgs values into the HKCU key but now how do I register the Typelib of the COM DLL in HKCU???

do you have a 'TypeLib' = s '{386515B1-2B6F-11D4-9048-004005719FF5}' (with your GUID)line in your .rgs file?

Why not change the HKCR in your .rgs to HKCU, build and register and have a look at the result with regedit? I'm assuming COM will look there for an entry.

Yes! Yes! I got it! Eureka! Smile | :)

I made changes to the .rgs file so that the coclasses are registered with HKCU.

HKCU
{
	Software
	{
		Classes
		{
			.....
		}
	}
}

Then I rewrote the

CComModule.RegisterServer()

function to register the type library using

RegisterTypeLibForUser

. That did the trick.

Thanks for your help!

what exactely are you trying to do ? the Outlook (Exchange) Server 2007 uses for example WebDav (being phased out) and now, Web Services to communicate with it - using these you can list emails, extract their attachments, do calendar type things

There is plenty of info on MSDN about this

Searching CodeProject for "outlook #import", I find several articles, including this one[^], which looks pretty good to me.

Just searching CP for "#import" yields several decent articles on Office automation - this one[^] is pretty good.

TabPage

Hi All,

I have a tabbed control on my dialog and wish to add other controls to it on 2 different tabs. I can see that .Net framework has "System.Windows.Forms.TabPage" control that holds the page. I wish to know if their exists anything equivalent in ATL/WTL? I am restricted to use these (ATL/WTL). I read about CPropertyPage / CPropertySheet but I am not sure if that can created using dialog editor (I did not see the control).

How can I add controls using dialog editor on Tab Pages to the CTabCtrl?

Thanks and Regards,
Atul.

Thanks for the reply. I have already read it. I am not sure if it clearly relates to my case.

For, it talks about creating property sheets/pages/wizard using program or single dialog based. I am talking about have a small CTabCtrl on the dialog apart from a list box and 2 check boxes on the dialog, etc. So it is not just showing one bunch of property pages. It has other things which I need to set on the Dialog editor interface.

Build dialog classes and add controls using the graphical editor in the usual manner so the classes reference descriptions with an .rc file:

class CStatusDlg :	public CDialogImpl<CStatusDlg>,
{
    enum { IDD = IDD_STATUS };
    ...

Within the .rc file IDD_STATUS (in this case) describes the the dialog

IDD_STATUS DIALOGEX 0, 0, 589, 442
STYLE DS_SETFONT | WS_CHILD | WS_VISIBLE
EXSTYLE WS_EX_CLIENTEDGE
FONT 8, "MS Sans Serif", 0, 0, 0x0
BEGIN
    PUSHBUTTON      "Update",IDC_BUTTON1,77,247,51,15
    GROUPBOX        "Drive Faults",IDC_STATIC,17,16,163,221
    ....

Then create the tab control and the dialog windows and add the dialog to the tabcontrol (Other dialogs similarly created can be added to other tabs on the same control in the same manner).

CTabView m_tabView;
CStatusDlg m_StatusDlg;

....

/// Create a tabbed view
m_tabView.Create(m_hWnd, rcDefault, NULL, WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS | WS_CLIPCHILDREN, WS_EX_CLIENTEDGE);

/// Create the first dialog based window to use as a tabbed view
m_StatusDlg.Create(m_tabView.m_hWnd,rcDefault, NULL);

....

/// Add the dialog based windows to the tab controls list (seems like a map with name/window pairs)
m_tabView.AddPage(m_StatusDlg.m_hWnd, _T("Status"));

....

Hi,

I'm marshalling some data in a timerproc thread using the GetInterfaceFromGlobal and Release function. However I noticed there is a high cpu usage when calling this function multiple times. Any ideas why this is happening?

Thanks

Hi,

I have for some time (ok, over a decade) had a gaping hole in my C++ knowledge, in that I don't really know much about the STL. I can use basic template classes and functions, but that's about it.

Now I need to learn about the STL, and there appears to be a dearth of good introductory books on the subject.
I have done a search on the forums, but the links seem to have expired.

So, does anyone have any recomendations for good introductions to the STL?

Thanks,

Richard
