Working on a windows form, I am trying to bind a listbox to a dataset and
want to set the displaymember & Valuemember properties of the listbox so that
I can retrieve the selectedvalue from a selecteditem in the listbox.
My code is very simple:
lstReports.DataBindings.Clear()
lstReports.DataSource = dsDataSet.Tables("Reports")
lstReports.DisplayMember = "ReportDescription"
lstReports.ValueMember = "ReportsKey"

If you have a comboBox which has it's DisplayMember and ValueMenber bound
to a datatable.
If I know the "ValueMember" value - is there a way for me to set
the index of the control to correspond to that ValueMember without having
to iterate over the values in the control to find the index of the matching
value menber?
There is a "FindString" method of the ComboBox which apparently iterates
over the collection looking form a match on...

I have implemented a combobox and have set the DataSource to an ArrayList.
I next set the DisplayMember and ValueMember properties.
When I run the code the combobox will display the proper text set by
DisplayMember but it seems that the
ValueMember doesn't work correct because when I go to use the SelectValue
property it never displays the correct text in the combobox.
Here is an example of my code:

I am binding a combo box to an ArrayList of
objects with a property called "Name" that is
assigned to DisplayMember.
How can I have the SelectedValue of the combo
return the instance of the object whose Name
property is selected in the combo?
I know that I can add a property like this:

Greetings,
As I understands it, SelectedValud of combobox reads its value from
ValueMember property of the combobox. This doesn't work with me. What
happens is just randome update. This is the code,
'Here I set connectin and commands
Dim cn As SqlConnection = New SqlConnection(str)

Does the ValueMember property in the ComboBox work like the DisplayMember
property. For example, if I set the properties:
comboBox1.DataSource = dataSet1;comboBox1.DisplayMember =
"Employees.LastName";comboBox1.ValueMember = "Employees.EmployeeID";

Sorry. The other post got sent before I was complete.
Does the ValueMember property in the ComboBox work like the DisplayMember

comboBox1.ValueMember = "Employees.EmployeeID"
If I select from the box a "LastName", I can retrive that selected name. How

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:

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,...

I'm a network technician in training and I need your help.
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.
