Any thread that calls CoGetClassObject or CoCreateInstance must already have joined an apartment, or the call will fail immediately.

This part is pretty straight forward.

This just seems to be another way of stating the question you asked.
Fortunately, no.
This is saying that the threading models of the client and server do not have to match but goes into no details on how this is achieved.

Dear Friends,
How to know whether the mouse button is Down
even if it moving.The WM_LBUTTONDOWN message is fired
only for the first time left button is pressed.
But how to know whether it is pressed all the time
though it may be moving.
|
|
|
|
|
|
Calling GetKeyState may be a better choice as it reflects state of the button when the current message was generated.

Add event handler for WM_MOUSEMOVE. If the WPARAM for this event has MK_LBUTTON set then left mouse button is down, or if it has MK_MBUTTON, MK_RBUTTON then the corresponding mouse button is down!
If you are using MFC then use void OnMouseMove( UINT nFlags, CPoint point ).
nFlags will contain appropriate flags to indicate whether left, middle, right buttons or whether shift key is down. Use bitwise and to find out.
E.g.
if(( nFlag & MK_LBUTTON ) == MK_LBUTTON )
AfxTrace( "You are dragging the mouse\n" );

Thanks for your replies friends.
I used like
<br />
SHORT LButtonDown;<br />
LButtonDown=GetKeyState(VK_LBUTTON);<br />
<br />
if(LButtonDown & 0x8000)<br />
{<br />
...code here<br />
}<br />
It works.Thanks a lot.

Hi,
I am copying data from a char array to a TCHAR array. In this case first byte of the TCHAR array element is same as char array byte ,but the second byte of the tchar array is FF sometimes instead of 00 for japanese character set.
because of this I am not able to display japanese characters in web page when my system locale is enlish(us)
