Those do entirely different things. T2OLE converts a TCHAR string to a Unicode string. SysAllocString() allocates a new BSTR on the heap. It's impossible to answer your question without knowing the function in question.

I wrote a COM by using VC++6, implemented IDispatch and IClassFactory. The name is RegUtil.CoRegistry. I have inserted HKCR\RegUtil.CoRegistry\CLSID = {xxx} and HKCR\CLSID\{xxx} = RegUtil.CoRegistry and HKCR\CLSID\{xxx}\InprocServer32 = path to my COM.
But I cannot using CLSIDFromProgID. It cannot find my program id??
But I can use CoGetClassObject.
I don't know what went wrong. At first, I create the project as simple com (IUnknown, IClassFactory), no IDispatch support.
After that I try to put IDispatch support into the project.
Anybody can give me some glint?

I have a small testing code in c# for the WM4.7:
<br />
using System;<br />
using Messenger;<br />
<br />
namespace MessengerDemo<br />
{<br />
<br />
class MessengerDemo<br />
{<br />
<br />
[STAThread]<br />
static void Main(string[] args)<br />
{<br />
MsgrObject msgr = new MsgrObject();<br />
MessengerApp mapp = new MessengerApp(); <br />
<br />
<br />
<br />
if(args.Length == 0) <br />
{<br />
foreach(IMsgrService service in msgr.Services) <br />
{<br />
Console.WriteLine(service.ServiceName);<br />
}<br />
} <br />
if(args.Length == 1)<br />
{<br />
if(args[0].Equals("logoff"))<br />
msgr.Logoff();<br />
<br />
if(args[0].Equals("quit"))<br />
mapp.Quit();<br />
}<br />
}<br />
}<br />
}<br />
The logoff method called on the messenger object works fine. The problem is the quit method, which is part of IMessengerApp, IMessengerApp2 and IMessengerApp3. I got no compiling errors with the code above, but if I run the prog with the argument quit, I got this Exeption:
<br />
D:\Projects\Messenger\bin\Debug>messenger quit<br />
<br />
<br />
Unhandled Exception: System.InvalidCastException: QueryInterface for interface Messenger.IMessengerApp3 failed.<br />
at Messenger.MessengerAppClass.Quit()<br />
at MessengerDemo.MessengerDemo.Main(String[] args) in d:\projects\messenger\messenger.cs:line 39<br />
Why it wants to cast it, the ImessengerApp3 should be part of Messenger.MessengerAppClass.... Anybody got an idea?

Hello everyone.
Out of process servers that expose COM objects, have no registry settings that specify the threading model they use. Suppose we want to find out their component's threading model, what can we do?
I'm specificaly interested in the threading model of the objects that MS Word exposes. Do they belong to an STA or an MTA? Type libraries don't include threading model information, so what can we do? Run some tests?! Or SoftIce on CoInitializeEx? !!!

Hi,
I have a few ActiveX controls in a browser, and I want
them to access each other's method( without creating a new instance)
Can someone tell me how can it be done.
Thanks,

Hi there,
I have an app here that already initializes COM via a call to CoInitializeEx(NULL, COINIT_MULTITHREADED). I have recently added drag and drop support, and am calling AfxOleInit() some time after the call to CoInitializeEx(). This works on my development machine no problem, but on another machine AfxOleInit()'s call to CoInitialize() fails with RPC_E_CHANGED_MODE. I don't understand why it works on my first machine, though I realize the failure on the second machine is due to the fact that it was initialized to MTA and now we are trying to use STA.
Any ideas? Surely you can use COM as well as drag and drop in a single application, right???
Thanks,
swine

Hi all,
How can I add a toolbar button and a Menu to outlook express (not outlook express 2000)? I am using VC++ 6.0. one more thing is I don't know what is the user's OS and the version of outlook.
I mean my program has to identify the os and outlook version automatically and add the component.
Can anyone help me please?
Thank you in advance.

I mean Outlook Express.
I had gone through the sdk in your site, but I couldn't follow. Can you please expland it further, or can you breifly explain me how can i add a toolbar button and a menu in outlook express.
Infact I tried to hook with windows as what S.Rod explained. I had gone through the PGP source but couldn't understad anything.
can you help me.

Using my SDK, it is not possible to do anything userinterface like(i.e. dealing with msimn.exe), only serverside stuff, as Outlook Express uses it. So the only thing possible is to rewrite the whole Outlook Express user interface, using all existing mail related stuff thru the SDK. A daunting task!
what you have to do basically is find the Window whose classname = "ThorBrowserWndClass" - Outlook Express 4 main window
"Ath_Note" - each new message you create or read OE is this class
"Outlook Express Browser Class" - main OE window for all ver.
Then you subclass the windows WindowProc. The XXXPluginInfo calls save and store information with regards to your your plugin information - toolbar/menu that is implemented in a dll(__declspec(dllexport)!!).
But yes, this code will only confuse you, unless the implementation is described too. I have tried using some very old code here on CP, that specifically drills down the OE window. Using Spy++ you could see that you need to use FindWindow() and FindWindowEx() API's to find-
Outlook Express Browser Class

SizeableRebar

RebarWindow32(this is the parent band?)
|
3 ToolbarWindow' s - i.e. OE's menu,toolband/rebarband/statusbar.
But although I can get OE's main band, any addition to the band(as in Nick Hodapp's rebarband code on CP) does not show a new toolbar button or menu next to the last item, as expected.
if you look at the msoe.dll(for OE6 - for 4.x it was called msimnui.dll??), you will see a function called LoadMappedBitmap(). but how to use it? I'm sure additions to toolbar/menu(as in msim) is very possible and works perfectly too. But how?? 
Hush,hush...

There is no documented SDK for doing things like in Outlook Express. May be there is no SDK at all.
Outlook Express, like a standard Windows app, has its toolbar and menus hooked by addins. For instance, PGP uses this technique :
__declspec(dllexport) void AttachOutlookExpressPlugin(HWND hwnd)
{
PluginInfo *plugin;
char szWndClass[1024];
GetClassName(hwnd, szWndClass, 1023);
plugin = CreatePluginInfo(hwnd);
if (plugin == NULL)
return;
SetProp(hwnd, "oldproc",
(HANDLE) GetWindowLong(hwnd, GWL_WNDPROC));
if (!strcmp(szWndClass, "ThorBrowserWndClass"))
SetWindowLong(hwnd, GWL_WNDPROC, (DWORD) MainWndProc);
else if (!strcmp(szWndClass, "Outlook Express Browser Class"))
{
plugin->bOE5 = TRUE;
SetWindowLong(hwnd, GWL_WNDPROC, (DWORD) MainWndProc);
}
else if (!strcmp(szWndClass, "ATH_Note"))
SetWindowLong(hwnd, GWL_WNDPROC, (DWORD) UnknownWndProc);
SavePluginInfo(hwnd, plugin);
return;
}
There are articles on Cp about hooking windows based on classnames, etc.

would you believe outlook express uses COM? But not for any extensilibity like visual additons to menu/toolbar - atleast in whatever undocumented stuff I know.

Let me rephrase then.
Outlook express exposes an underlying API known as MAPI to allow someone to send/retrieve emails and stuff. In fact Outlook express is a MAPI client, like Eudora, Outlook, ...
There is no other API. Adding toolbars or menu options is only the result of a general windows hooking technique.

Hi Stephane,
I thought Outlook Express uses Simple MAPI(SMAPI).But you are so wrong, because this is not documented. SO I don't really blame you. COM acces apart from SMAPI/MAPI is also possible, cause OE is programmed as a bunch of COM servers. I have been working on this for sometime.
If the topic interests you,let me know(and your email)

Yes, even though that's off-topic. Has this anything to do with the original poster request ?

Outlook Express consists of msimn.exe(the client),msoert2.dll(run time string anf other util stuff),msoeacct.dll(accounts),msoe.dll(the main OE com server), msoeres.dll,msacctres.dll(account dialog resources) etc.
Most of Outlook Express's folders and mail access is thru CLSID_StoreNamespace.
{E70C92A9-4BFD-11d1-8A95-00C04FB951F3}
IID_IStoreFolder - {E70C92AC-4BFD-11d1-8A95-00C04FB951F3}
IID_IStoreNamespace - {E70C92AA-4BFD-11d1-8A95-00C04FB951F3}
Outlook Express client(msimn.exe)uses these system interfaces(Outlook Express is a system component in a certain sense) and folder/mail and notifications are available just as for MS Outlook.
Not surprisingly,MS Outlook also uses some of these interfaces! (esp account,transport etc).
other common system interfaces include message transport, MIME message creation/encoding/decoding, account related interfaces . inetcomm.dll among other things,contains the encapsulation for mail transport(HTTP/SMTP/IMAP) for MIME messages and other TNEF specific stuff)mlang is for multi lingual features as documented.
The interfaces I'm talking about are very old(97) and a lot of other changes and newer implementations are inlcuded in later versions(5.5x+)like msn integration. probably these newer interfaces are never going to be documented as well.
This is how I can launch the client thru undocumented means.

typedef HRESULT (APIENTRY *PFNSTART)(DWORD dwFlags, LPCSTR pszCmdLine, INT nCmdShow);
HINSTANCE hMod = LoadLibrary("C:\\Program Files\\Outlook Express\\msoe.dll");
if(hMod)
{
PFNSTART pfn = (PFNSTART)GetProcAddress(hMod,"CoStartOutlookExpress");
//combination of other flags -

DWORD dwFlags = MSOEAPI_START_INSTANCEMUTEX;
//set nShow to SW_XXX
int nShow = SW_SHOW;
LPTSTR szCmdLine = {"/2"};
HRESULT hr = pfn (dwFlags,szCmdLine,nShow);
if(FAILED(hr))
return FALSE;
}
Is it off topic?  Actually, I'd like you to check out my little SDK here.. I know you are a COM programmer and am looking for beta testers/programmers for more ideas etc. Thanks in advance.

I am afraid that it is. The poster wants to customize Outlook express toolbars and menus.
I have just given a glance at the OE SDK you refer to and that's a good job. However, the COM layer you add to it makes it nice for anyone who would like to drive Outlook express from an external app. But this does not bring much for the purpose of building an Outlook express addin.

you are quite correct in the sense of a visual addin for outlook express. no, the ms docs do not seem to suggest this - although there are certain IOEExtension and IOEExtensionMenu interfaces, but I do not think such an extensibility is possible. So I'd like my SDK also to have some means of visually addin menu entries/toolbars. I need some help with this.

The code I have posted above is an excerpt from PGP, which actually plugs itself in Outlook Express, along with a toolbar button and a menu option. This exemplifies how window hooking techniques can gain access to an arbitrary app.

I have just posted another update here(ugh! html!?!) and you can take a look at the interface declarations and how to access everything thru raw OE object model.
Interesting,huh!
