Hi,
I have a few million data items being received by my program and I wish to
store them in a list, with each item being inserted in any position in the
list. Any performance tips so that my program runs ok?
I have checked out the STL and have thought of using vector, set, list,
deque and map. I dont know how these things are implemented so not sure
which is best to use or if i should implement another data structure.
Perhaps any...

I have a linklist class, and I have around 20 other classes that need
to access the same info (the data) that is contained in the linklist
class.
What would be the best way to share access to the data between all the
classes? Should I just have all the classes adopt the linklist class
as a friend, or use a global for the linklist, then access the data

Hi, back again with another list box problem, 3rd in two days!
I am wanting to create a list box that lists all the results of a
query. I am using Access 2000, and I'm sure this is easier to do in
Access 2003, but seeing as I don't have it I'll have to make do! using
the list box wizard I try to base the list box on the query i am using
(qryAvailable_Cars). However i always receive an error message saying

Is it possible to link one drop-down box to another? For example, if a
name is chosen from a drop-down list, can another drop-down list then
automatically display the person's office as a result of the choice
made in the first drop-down list? If so, how can that be done? I am
working with 'Teach Yourself Microsoft Access' and I didn't see it
discussed in that book (if it's even possible to do). Or would I just
have to create linked tables...

Hi,
I am a newbie with C and am trying to get a simple linked list working
for my program. The structure of each linked list stores the char
*data and *next referencing to the next link. The problem I get is
that I am trying to link a struct that I have defined and its refusing
to link. I have tried casting my struct into char * but attempts to
cast it back to its original struct to access its contents only seg
faults.

I want to write a method to remove the last node of the linked list.
But the error "Access Violation" exists and the error point to this
method.
What does it means by Access Violation and how can I debug it?
Thanks
void RemoveNode(StepNodePtr pList)
{ StepNodePtr preq, q;
q = pList;
preq = pList;

Hello,
The app in question is lives on a Windows 2003 server with .NET 2.0 running

Hello All,
I am creating a date base in access. I want to create a dropdown list box that is connected to another dropdown list box.
You start with a dropdown list that has 5 choices and each of these choices will call another dropdown list box when one of the choices from the first gets selected. (I hope this makes sense)
All of this is being done on a single form.
I know how to make a (sub) dropdown list not seen before the action...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
