The following code works fine when previewing a Crystal report using
ASP, EXCEPT when it gets to a report using a SubReport and its
associated parameters. The whole report just comes up blank with this
error message: "The Error Message was: Error detected by database
DLL.from: Crystal Reports ActiveX Designer".
What am I doing wrong in the SubReport section below and how do I
properly pass in sproc params to the subreport? Thanks.

Hi,
I've been working through a number of turorials to try to learn more about
retrieving data from a SQL database. I think i've mastered techniques where
i create a sql string in the page and pass it to the Db and retrieveing data
from a stored procedure, but I can't get the hang of parameters.
I have a method where I can get the parameters passed to the sp but it
doesn't want to return any results. Here's a copy of my code:

I'm using SQL Server 2000 and on my page, I'm simply creating a
SQLDataReader and filling in Labels with the retrieved (single) record.
However, how can I prevent from getting errors when a field is null?
I've tried something like this (experimenting with IsDBNull):

If dtrData.IsDBNull("Address2") = True Then
lblAddress2.Text = ""

Is it possible to pass a null value to a stored procedure in .net?
I have a search Sproc that can take one of two numbers to search on,
but not both. I use the code below to pass a null value to the sproc
if a TextBox is empty.
SqlCommand getLesNumbers = new SqlCommand();
getLesNumbers.CommandText="usp_getLesNumbers";
getLesNumbers.CommandType = CommandType.StoredProcedure;
getLesNumbers.Connection = msoConn;

I think I have discovered a bug in the handling of null values (vs NULL
values) passed as parameters to a stored proc.
I have always believed that the database handled NULL and null the
same. The following statement returns the expected results:
select case when NULL is null then 'SAME' else 'DIFFERENT' end from
sysibm.sysdummy1;
returns SAME.

I am using vb.net 2005 and SQL server 2000. In my table I have a date field

a date value into the appropriate text box. I then want to pass the value of
this text box as a datetime variable to my stored procedure which inserts or
updates the row.
As I mentioned above, the textbox may be left blank - hence I would want to

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...
