Subject: Ole doubt
Hello all,
I've a doubt in ole automation.
I cld able to create an automation server which can be called thr'
IDispatch as well as using the Typelibrary. I used the default interface
(created by an OLE server) to add the methods and hence created the
dispatch as Interfaceobject.CreateDispatch("Servename.Application")
I want to add a second interface. So, after adding the second interface,
the .odl file looks like this. Now, if i make the foll. calls in the
container, the second call for CreateDispatch
(where i'm using the Classname) returns a null dispatch pointer.
I don't want to include the IID of the second interface (defined int he
server) in the container. Is there any other way to do this???
Its a bit urgent,
So, can u pls. reply me asap,
Best Regards,
Nirmala.

Subject: WCHAR
Hello,
I am using NetUserGetInfo() which requires that a server name and user name
are passed as Unicode strings (LPWSTR).
I don't know how to manipulate Unicode strings at all - All i need to know
is how to convert a char[] to LPWSTR.
TIA,
Gef Howie

Subject: Query on RUNTIME_CLASS() !!
Hai ...,
It would be the greatest help a man can ever do if u solve my prob.
---> I derived "CEquipment" from "CObject" & using CObList to store
it. The code
CEquipment* ptemp = (CEquipment *) pDoc->EquipmentList(pos);
ASSERT(ptemp->IsKindOf(RUNTIME_CLASS(CEquipment));
is causing a Assertion failure.
*) I used IMPLEMENT_SERIAL() for "CEquipment"
*) I declared CObList EquipmentList;
?) should "CObList" object also should be said IMPLEMENT_SERIAL().
please help me.
Thanx to everyone who spend their time knowing my problem ..
Yours friendly,
Kameswara Rao M.

From: Rick Zhang <otv_zhang@163.NET>
Subject: SetviewportOrg
Hi everybody:
I want to know how to get the scope of the viewport. I used the function
"GetViewportExtEx(HWND hWnd, LPSIZE lpsize)". The function worked fine,
but the value it returned is: lpsize->cx = 1, lpsize->cy = 1. It seems
not right.
I wonder if there are some mistake in my code:
--------------------------------------------------------------------------------
----
HDC hDC;
LPSIZE pwRet;
...
if (GetMapMode(hDC) != MM_TEXT) SetMapMode(hDC,MM_TEXT);
if (GetViewportExtEx(hDC,pwRet))
{
xClient = wRet.cx;
yClient = pwRet->cy;
...
Thanks in advance.

Subject: Re: Cyclic thread - How To?
Hello Jurgen,
Create an event in your primary thread that is going to signal your
worker thread to stop working, make sure the event is not triggered. =
Then
start the worker thread. Here's what the worker thread function will =
look
like:
UINT WorkerThread( LPVOID pvoid )
{
HANDLE* phandle =3D pvoid;
while( ::WaitForSingleObject( *phandle, 500 ) =3D=3D WAIT_TIMEOUT ) //
set the wait time to be whatever you want it to be I'm using half a =
second
(500 milliseconds)
{
// Do your work here, it hits this spot every 500
milliseconds (or whatever time you put in) plus how long it takes to =
execute
the code you put here
}
// OK main thread just signaled us to quit working so let's exit
return TRUE; // or whatever you want the thread's return code to be
}
The code above will wait half a second then execute the code in the
while block, then wait again. It will keep doing this until you set =
the
event in the main thread that created the event and started the worker
thread. If you would like more timers in the worker thread, write me =
back,
I've been doing a little experiment with timers and threads and think =
I've
come up with a clean solution.
At any rate, write me back directly if you need some more help, or
to just let me know how it worked out.
Thanks,=09
