Hello,
I am trying to perform a LEFT JOIN on a table which may or may not have
matching rows.
If there are no matching rows, it returns NULL's for all the missing fields.
Is there anyway of returning the default values for that table instead of
NULL's, in a portable way?

I have two questions which are very similar:
Is it possible to return an object in C++. Below is part of my code
for reference however I am more concerned about the concept. It seems
like the function below is returning a pointer to pointers who are
GUID. I am trying to write a wrapper to use in my VB code and what I
would prefer to do is be able to return an array of GUID. I remember
(not sure) that the concept of arrays does not really...

Can someone please help, I'm trying to pass an array to a function, do some
operation on that array, then return it for further use. The errors I am
getting for the following code are, differences in levels of indirection, so
I feel it must have something to do with the way I am representing the array
in the call and the return.
Below I have commented the problem parts.
Thanks in advance for any help offered.

I'm fairly new to C# and I am having some problems
understanding int variables and null values.
I have created a class that populates the values of it's
fields from a DataReader in it's constructor. Those fields
are modified during various methods in the class. One
method updates the database with the values of the class
fields. I have everything working fine for string fields
but am running into problems with integers and null values.

I've been attempting to pass a chunk of data back from a child Windows form using public properties on the form and have been getting some odd errors. I wanted to return a row of data to avoid creating many public properties on the form to do the same thing. At first I tried returning a DataViewRow. This worked fine until I reached the phone field on the parent table and the code

My database has 2 tables: Table1 & Table2. If a field is not null on a
record in table2, then the not null fields in table1 that correspond to
the records in table1 needs to be updated to match the field in table2.
What I have is a form that is linked to Table2. If the users want to
change a field in the main database (table1), they fill the change in
to the form (which is linked to table2) If there is no change to the
field, they simply...

Hey, I've got a bit of a strange problem caused by a situation I'm in.
I'm writing a DLL for a friend of mine in C++, and he plans to use it
in delphi. The DLL needs to return strings, and we doubt that a string
would return well to a delphi program, so the only thing I could think
of was returning a char*, which obviously would be very dangerous as
the array would be being declared as a local variable and would only be
returning it's...

I am working on an Inventory Database in Access 2003. I am having trouble with a report I designed to show current inventory in stock. I have a form (frmInventory) that is unbound. There are four combo boxes on this form that allow the user to select Location, Vendor, Category and SubCategory. These selections (or blank fields) are then passed on to a query (see SQL below) and a report opens to show the inventory. This worked really well...

Overview:
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,...
