I am trying to populate a combobox with a lisy of items. I want the 1st item
to be "Make a Selection" and the following items will be names from a table
in my DB (See code below).
When I run the project, the combox box initially displays an empty
selection. When I click on the drop down arrow I see the "Make a Selection"
followed by the other choices.
How can I move everything up so that the "Make a Selection" is the default
value in...

Below is my code for a combobox. Basically, I have 2 comboboxes. 1
box is the application selection and the other retrieves data from the
dataset (SQL Server) to populate the drop down in the otehr box. I
want to make a selection in the app combobox, update the second box
and when I select a new app, it should remove all items in teh 2nd
combobox and refresh the list with only the selected app. With this
code it appears the binding is...

I am trying to figure out how to clear all items from a combobox
(Access 2002).
On my form, I have to comboboxes. Combobox 2 is populated with a set
of child data dependent on the parent data item selected in Combobox 1.
This is done through the .AddItem method of Combobox 2 looping through
the recordset.
This works fine, until --> the data item in the Combobox 1 is changed,
then Combobox 2 just appends the "new" related child data...

In our VB.Net Windows form application we have a combobox
pre-populated with a list of items. What I need is simply
clear everything from it's dropdown, when a button is
clicked. I tried everything I can think of, such as set
data source to nothing, etc., but still not been able to
make it happen.
Can someone show me how to do it?
Thanks

I am populating a ComboBox at run time. I insert the first value of
"Choose Value"
cboTaxValue.Item.Insert(0, "Choose Value")
Then I loop through the rest of the values to be added to the combobox.
My problem is that when I try to clear the ComboBox it clears the items
that were inserted into the ComboBox, but does not clear the item I
selected in the ComboBox... For Instance.

And the code below works fine the first time I click Column 2, leaving Column 1 blank.

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...

I haven't had much luck with specific controls, their properties and loops in the past. I thought I would share this tidbit of code, feel free to modify/modularize in any way to suit your needs. This function may be called from the combobox after_update event or a "clear filter" buttons after_update event. I placed this in a module. Oh, one more thing... I happened to have my FK in column 1 of the combobox, this may need changed. Sorry if I...

Hi all,
I'm relatively new to javascript, and have created a new form, which I adapted from the instructions in http://bytes.com/topic/javascript/answers/848693-load-forms-depending-upon-selection-combobox but it's not behaving as I would like it to.
Basically, I need three comboboxes. The options in the second combo depend on the value selected in the first combo. If the first and second combos have values selected, then a third combobox...

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
