I have a tabular form that has a combo box on it that is reading from
a database. When that combobox changes, I want it to lookup a database
record to get a value and set the value into another text field on the
same form and record. Everything works fine except for that the change
event updates everything on the form not just the current recordset
that I am in and where the change event was started. Here is my code
any help is...

I need the code to update the database when Save is clicked and a text field
has changed. This should be very easy since I used Microsoft's wizards for
the OleDBAdapter and OleDBConnection, and DataSet; and all I'm doing is
showing one record in text fields, allowing the user to modify the text
fields, and then updating the database again when the user clicks the Save
button. The fields already show the correct data record since I have...

ValueMember property of the combobox. This doesn't work with me. What
happens is just randome update. This is the code,

Hello,
(Windows forms - SQL Server)
I fill my datagrid with a stored procedure that includes relationships
to lookup tables so that users can see the values of the combobox
selections rather than the key value that are stored in the table.
It works well if the comboboxes are selected when the row is created.

I am having an issue with graphical corruption upon re-selecting a
combobox which upon 'selected index change' event should list file
names in that folder in a separate combobox. Here is the code:
private void comboBox2_SelectedIndexChanged(object sender, EventArgs e)
{
IniFile INI = new IniFile(@"c:\\data\TM.ini");
string MisFileDir = INI.IniReadValue("Main", "MisFileDir");

Hi all
I'm beginning my foray from VBA into VB 2005 Express, and enjoying
some of the efficiencies it provides! I'm stuck with some dataset
handling however that I _think_ can be automated but I can probably
code what I want to do the hard way. I've searching around online but
can't find an answer to this specific question.
Here's the situation: I have a dataset table with 3 fields: one
indexed as a primary key and the other two...

Ok this should be simple.
I made a form, added a combobox (for selecting items to edit, not for updating fields), several textboxes, a few checkboxes etc. On formshow it connects to my database, draws down the existing data, no problem. All the records in the datatable that were the result of a query, I could select from, and the other databound components would display the records contents, no problem..... however.... when i add a new row, the...

Hi! I have just started programming C# and I have a problem.
On my main form, I have a combobox filled with names of people. To add more people to the combobox I want to open up a dialog box and fill in the person's name in a text field and when I hit the save button it should update the combobox on my main form. How do I do this?

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...

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,...
