From secondary threads post messages whenever appropriate to themain thread and let the latter doing the actual GUI updating work.

As I already suggested, from the worker thread, send a message to the main thread whenever you need to play the animation and let the main thread itself to play it.

Many Thanks Randor .... Actually ..I am modifying code of very large application, which has the same case, number of times, so I looking for a simply way to do this, with out change much in the existing code, So I planed to have a thread that plays avi and calling it when every required from all the dialog boxes...Am I going the right way...or is there any other work around...pls advice...

The code in my above response requires very little changes to the class, it even supports your multiple AVI resource ID and pane ID in the thread class. If you follow the instructions I have provided I am very confident that it will solve your problem. Please try it and see.
Best Wishes,

Hi All,
I am using VC++ 2003 and Oracle 10. I have created a table in Oracle.
The table has ten fields including a primary key (field).
Is there any function in VC++ to know the extracted field (from database) is primary key?
I am using ODBC..

|
|
Can't you just execute SQL command "DESCRIBE tablename"?

How would that work?

I have not used oracle in some years, I just remember there was a command 'DESCRIBE' table
**Update**
Found some old code!
I think he can do this:
SELECT CONSTRAINT_NAME FROM USER_CONSTRAINTS WHERE TABLE_NAME = "table" AND CONSTRAINT_TYPE = 'P';

True, but I couldn't find where it populated anything regarding a primary key.

do you think it's my solution?

Only you can determine that. Unless you try it, you'll never know.

By calling accept() and noting the client's name and port number that it returns.

Hello everyone,
Why in the following code segment (along with Bjarne's comments), function get_new can not deduce template parameter type to be int by its return value assignment to int * p1, and deduce T* is int*, and so T is int (e.g. as we did for function release in the same sample below)?
class Memory {
public:
template <class T> T * get _new ();
template <class T > void release (T&);
/ / ...
};
template <class Allocator> void f (Allocator &m )
{
int * p1 = m.get _ new <int>();
operator
int * p2 = m.template get _ new <int>();
/ / ...
m.release (p1);
m.release (p2 );
}
Explicit qualification of get _new() is necessary because its template parameter cannot be deduced. In this case, the t e m p l a t e prefix must be used to inform the compiler (and the human reader) that get _new is a member template so that explicit qualification with the desired type of element is possible. Without the qualification with template , we would get a syntax error because the < would be assumed to be a less than operator. The need for qualification with template is rare because most template parameters are deduced.
thanks in advance,
George
