Hi. I'm just getting started with vb.NET development in VS 2003. I have a
datagrid that lists a bunch of customers (hospitals). Next to the customer
number and name is a bunch of checkboxes that I want to use to check whether
it's a key account, defensive account, ambulatory surgery center, academic
hospital, or MD office. The grid opens with the checkboxes in edit mode and
shows whether a box is checked or not. This initial binding is...

Hi,
The SqlParameter myPM =new SqlParameter("@Address", txtAddress.Text) is
working for update,
but SqlParameter myPM =new SqlParameter
("@Address",SqlDbType.NVarChar,90,txtAddress.Text) is not working.
The Address column is DataType NVarChar 90, no problem.
Any idea?

Hi,
I'm experiencing the problem mentioned in the title above. Briefly, I
build a page in which I include a class. This class contains a
procedure to add a value to an ArrayList. The value is hold by a
structure. So all elements in the arraylist are in fact a structure.
As you can see in the code below. Now what I'm trying to do is for
each value in the Arraylist create and add a parameter. Then I try to
execute a SP. This only works if...

I found this method code in Enterprise Library 2.0 and I really don't have
idea what does it mean.
public virtual void SetParameterValue(DbCommand command, string
parameterName, object value)
{
command.Parameters.Value = (value ==
null) ? DBNull.Value : value;
}
In my guess, the "(value == null) ? DBNull.Value : value" means if "value"

I'm writing a data conversion application to support a system migration. The code is reading formatted text files and loading them into MS SQL 2005 database tables. I wanted to call the existing INSERT stored procedures in the database to perform the update, yet I don't want to hard-code all the parameter names. Below is a bit of code that reads the imported data from the 'Data' DataTable, and prepares to insert it into the database table...

I have the following code that adds SQLParameter objects to an
SQLParameterCollection object (well at least that's what I am trying to
do!!)
When the line of code runs that adds the parameter (colParams.Add), the
actual function call (CreateSQLParam) executes with no errors but the actual
".add" fails with an "Object reference not set to an instance of an object"
error. At first I thought it was maybe because I did not use the "New"...

As some of you may have seen (since I have had to practically live on Bytes.com for help) I am working on a program that reads a given .txt or .csv creating an object of an array (lines) per line of text. The program then creates a file and/or folders based off the text lines in the file.
I am running tests on text files to make sure I've killed what bugs I can and I got an error I don't understand.
The text file contained this data:

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
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
