Specifically for joint tables...
tblStudents
tblClasses
tblClasses_Students
Is it be good programming to use a composite primary key in
tblClasses_Students (where the key is ClassID and StudentID)? I
enventually will convert the Access db to an SQL db. I've always used
single primary keys based on long integers, usually autonumbered.

I am a bit confused in creating a composite primary key. I have three table
with two of the tables containing primary keys. I have two of the tables
(each with a primary key) having one to many relations with the table
containing no primary key. Do I just create two primary keys on the table
that does not contain any primary key for this to become a composite primary
key?
Thank you in advance!
Still a newbie,

Hi,
I am unable to add a pager for this composite control.
I had created a composite control in C#. The control is having 5 labels, one radio button and one DropDownList control. The composite control should display 2 columns and 2 rows per page. I am able to display 4 Composite Controls independently, when the user is changing the index of the DropDownList control, automatcially the output should get reflected on the composite control...

I have an ATL composite control which I drop into a tab control dialog page
of an MFC application. When I click on the composite control and then click
anywhere outside the MFC application, the application immediately hangs!
Spy++ indicates that the application is hanging on the WM_GETDLGCODE message.
This problem does not happen if the ATL control is a standard (that is,
non-composite) control, neither does it happen if the composite...

DataGrid cell, so I'm hoping someone might have stumbled across this problem
before and have some advice.
My composite control is a date picker which contains a couple of basic text,
drop down and image button controls. My control follows the composite design
guidelines carefully and behaves perfectly when used on a web page. It uses
ViewState and gets events from is...

I have created a fairly basic composite control consisting of a Label
and a TextBox. In the overridden Render function, I'm creating a
table with two rows and each row contains a cell (td). The Label and
the TextBox are each rendered in one of the cells. Everything renders
fine. The problem is that depending on the column the control
represents I may want the textbox to be a different visible size
during both design and runtime. I...

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,...
