Hello All,
I am running in to a situation where the listbox is not refreshing for me.
I am using a timer to cycle every second and call the timer_elapsed() event.
in the time_elapsed event Method I have code that checks to see if a DB
table has been updated.. if so the new new data is uploaded to the listbox
by calling
lstbox1.datasource = myDBDataSet;

I am populating a multiselect Listbox from a dataset, with the content of
the listbox filled by one table, and the selections determined from another
table. So far, I have been keeping the dataset a denormalized mirror of the
database, but I'm not having much luck getting the selection logic down (I
haven't found a 'hook' where I can access the listbox object as an object to
set the listitem's selected property before it gets rendered)..

I have a strange problem with a databound listbox. It may be because of how
I use it, but I am stumped by this behavior. Here is the scenario:
I have a multiselect databound listbox that belongs to a panel control. In
the Page_Load event, the panel listbox control may be moved from one panel
to another depending on selections that the operator makes. Everything
seems to work fine except for one thing. The selections that are made in...

I'm filling a listbox in my code and I notice that when I run the program
the first item in the listbox is always selected. I haven't selected
anything though. When I have it run a quick unselect loop I still end up
with one item always selected.
If I unselect the first item, click on one further down the list and then
unselect that one, the first item is automatically selected again. Is this
normal? Do I have some property set that I...

Hi everyone,
I have a ComboBox that when changed, calls a method to change the content of
a ListBox.
I'm also using the Listbox's SelectedIndexChanged event to change other
control values on the form.

When I bind my datasource to the ListBox, I find that the

Hi all.
I've been stuck on this problem for a while (I'm a newbie). I have a
listbox with several collection objects, some of them being identical.
When one of the collection items is selected in the listbox, the values
of that collection item can be set but if an identical collection item
is also present in the listbox, its variables are set as well.
I think it has something to do with the SelectedIndexChanged and
databinding. I have...

Hi,
After viewing the entire Visual Basic 2005 Express Edition for
Beginners video series, I have begun building a database driven
application that will make use of listbox1 (multi-select) determining
what shows up in listbox2 (multi_select), which determines listbox3,
etc.... Each each listbox is populated from a different table in the
same database.
The databinding examples given in the video seem to leave no way for a

Hello all:
Clearly, I'm not getting it! Here is the scenario:
On a web page, I have two list boxen and a text box. The first listbox
is populated at page load time (if it is not a postback). This listbox
has AutoPostback = True. When the user selects an item from this list,
the second listbox is populated with more items relevant to this
selection. I am using an SQLDataSource web control for this. These
items are headers. I want, when...

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:

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
