Hi,

I am not sure about the user id part , but getting the current date is
fairly simple.

Just use the CTime class and check out its data members.

Why Not ! First of all, you didnt mention whether you are using c or c++.
If you are using c++, you could simply use references . else, you could use
a pointer to the structarray and use an index as well.

Say, the array of structure is defined as
#define MAXSIZE 10
struct x
{ ....
} structarray[MAXSIZE];

Your function would be declared as

void myfunc(struct x *tmpstruct);

main()
{

//    YOu could now invoke the function as

    myfunc(&structarray[0]);
}

IN your myfunc, you could always do

void myfunc(struct x *tmpstruct)
{
    for (i=0;i <MAXSIZE;i++)
        {
           // do something with(tmpstruct[i]);
        }
}

This code would work perfectly well. Hope this helps.

Hello to all MFCers!

I was wondering what the "best" method might be to create a widget
(let's say for example a special logarithmic progress indicator) that
should be easily (re)usable and as easy to construct as possible.

I can see several methods of doing this but cannot find any clear
documentation that shows advantages and disadvantages.

(1) I might try to create a OLE, OCX, ActiveX control. This seems quite
complex and to generic especially if I only need to reuse the component
in MFC. I also do not like the to complex interface compared to a nicely
designed class interface.

(2) I can create a child window that is encapsulated in a CWnd derived class
and manage the control as a Window.

(3) I can go for a simple class that just behaves like a CWnd class but
in reality is only a internally defined region of a window that knows how
to redraw itself, to move itself etc.

(4) I can try to create a class that is derived from a "native" control
class but draws itself.

and some other even more unusual methods seem possible ...

Can someone give me some directions on how to compare all this available
methods or point me to some useful existing documentation.
The best would be an available example that shows some or all of this
possibilities.

Regards and thanks for any help in advance
