There maybe some acceptable uses of such an architecture. We use it for an integration into a browser-run hospital information system. A web page of that HIS contains a link with a special protocol, and that protocol is connected with our application.
For this to work, you need to install the VB program on the local machine, and also register your protocol. Take a look at the registry at HKEY_CLASSES_ROOT\http or https or ftp for examples how a browser gets started when a webpage is to be opened.

You cannot do that, it is a security issue. How would you feel about some website running a program on your PC without your knowledge?

In which environment? WinForms[^], WPF[^], ASP.NET? There's also an example on vb-helper.com[^] 
If you need help with your code specific, then I suggest you include it in the question.

I really wouldn't bother with licensing any more but you've got plenty of choices: "licensing sdk .net"[^]

Depends on how the page is implemented; you could contact Cisco and ask them.
Otherwise, you'll be hunting the JavaScript, looking where it dynamically loads the data. It'll be fetching XML or JSON from a URL, probably passing some arguments along. You can usually see it fetch this data in a tool like Fiddler/WinPCap.
Alternatively, there's a WebBrowser-control that acts like a webbrowser, but that can also be access using code. You could automate that to do whetever the user would do.

i have an access database with a particular column which contains the words "male" and "female", and would like to know the number of times each word reoccurs. and display the value in a label. thanks @all

You use a WHERE caluse to filter the dataset eg
Select count(*) from Table WHERE ColumName = 'male'

Assuming the colun is called Gender, and the table is called Person
SELECT [Gender],Count(1)
FROM [Person]
GROUP BY [Gender]

thanks alot it worked as expected. But please how do i sort out and select files using two columns?
|
|
|
|
|
Sort using an ORDER BY clause
Select using a WHERE or HAVING clause.
I suggest you learn some basic SQL - try here: SQL Tutorial[^]

Hello, my apologies if I'm on the wrong forum. First time posting a code question anywhere since I was a student. (It's been a while.)
I'm trying to create a Customized ComboBox for an application and I want to have a property which is a list of strings. I've simplified my code down to just that to make things hopefully simple.
I can create normal properties that are just string variables and they work in the designer. But when I try to make a property that is a List(Of String), it appears to work but I get the following error when I try to add a string to the list in the designer.
> Constructor on type 'System.String' not found.
My code is below:
Imports System.ComponentModel
Public Class CustomComboBox
Inherits ComboBox
<Editor("System.Windows.Forms.Design.StringCollectionEditor, System.Design", _
"System.Drawing.Design.UITypeEditor,System.Drawing")> Private MyListOfStrings As List(Of String)
Property MyListOfStringsProperty() As List(Of String)
Get
Return MyListOfStrings
End Get
Set(ByVal value As List(Of String))
MyListOfStrings = value
End Set
End Property
End Class
Any help is appreciated, Im'

Dim job = From J In QryGen.co_jobs Where J.co_id = 1013 And J.industry_mas_id = 5 Order By J.job_id Descending Select New With {J.job_id}
this my query. in this I would like construct the query on runtime for where condition.
sometime need to include some other fields to where condition.
I need help.
Thanks in advance.

Try chaining the Where clauses:
Dim query As IQueryable(Of Job) = QryGen.co_jobs
If filterById Then
query = From J in query Where J.co_id = 1013 Select J
End If
If filterByIndustry Then
query = From J in query Where J.industry_mas_id = 5 Select J
End If
Dim job As IQueryable(Of Job) = From J in query Order By J.job_id Descending Select New With { J.job_id }

Only if you intend to write one and get stuck. If you're looking for some ready-to-go code that implements said functionality, I'd recommend Google.

If you're going to write it, then you decide where they go. There's however no place where the user cannot look if he/she has administrative rights. Whatever you access locally, my debugger will know.

You're asking about very specific functionality on a 3rd-arty library and hardware setup. Your single best source of information is going to be Logitec's forums.
The chances of anyone here who has done any work on the G keyboards seeing your post is extremely low.
You go where the highest concentration of people using the library are going.
