You could load it into a HTML view (or with a bit more manual labour directly into a IE window), and call IHTMLWindow3::print on it.

We say "get a life" to each other, disappointed or jokingly. What we forget, though, is that this is possibly the most destructive advice you can give to a geek.

I think it is possiable by masking the icon or bitmap with background colour. Then show that masked bitmap.

Nice talking to you. Blush | :O

Methods & Properties ActiveX in VS 7.1

Am I correct in thinking that all the functions of an ActiveX is placed in the Class (e.g. Message Maps, Events etc) and the Prop provides the Methods & Properties for accessing the control.

Do you use the Dialog form on the Prop to place indicator controls( static labels, edit boxes etc) - How is this dialog used?

Not quite sure how to expose properties ( can see how to add them) but how do you tie them to Class vaiables.

Not been able to find a simple example using VS 7.1

Re: Problem Querying MSysObjects(ms-access table)

Hi all,

When i try to query MsysObjects table following error is caught(try-catch).

[B]Database error: Too few parameters.Expected 2.[/B]

These are the two lines used to run the SQL query in vc++.

// Build the SQL statement
SqlString = "SELECT Name FROM MSysObjects where type = 1 AND (Left([Name],4) <> \"Msys\") AND (Left([Name],1) <> \"~\")";
// Execute the query
recset.Open(CRecordset::forwardOnly,SqlString,CRecordset::readOnly);

I am using CDatabase class.

Please Help!

Thanks a lot Subramaniyam . it works, just a little modification is required:

SqlString ="SELECT Name FROM MSysObjects WHERE type = 1 AND((Left([Name],4) <> \'MSys\')AND(Left([Name],1) <> \'~\'))";

Heartfelt thanks,

Shutdown doesnot closes the Socket,resources attached to this
Socket are not freed.For this u have to use the Close,It is
to disable sends and/or receives on the socket.

Close-: it releases the socket descriptor, so that further references to it will fail with the error WSAENOTSOCK

to check if the thread is alive or not :

DWORD dwExitcode;
::GetExitCodeThread(cwt->m_hThread,&dwExitcode);
if(dwExitcode==STILL_ACTIVE)
{
bla..bla..
}
