I need help i have been trying all day yesterday and all day to day to try and get this working
What i trying to do is create buttons dynamically i can now do this thanks to Dave Kreskowiak he told me how to wire up the events for this but i just can’t get my head round it
I can get the event to work but the event is the same for each button
I need it to get the relevant drink and price from the database and put them in a list box
Dave mentioned directcast i tried to find out how to do this but with no joy

If all your buttons fire the same event, you can cast the object passed into the click event ( typically called 'sender' ) to a button, and then you can examine it's name or tag to work out what button was clicked and change the behaviour accordingly. I'd typically use the same event handler if all the buttons did roughly the same thing, for example, if three buttons all added a different value to something, I'd store the value in the tag property.

It doesn't come with the Express editions, as far as I know. I could be wrong because all I have is the Team Suite, which comes with everything.

I doubt anyone will willingly post you the code but a simple bit of research will get you the following

I've been trying to get this to work for ages now.
All I need is to be able to cast an object as a data type that's type is stored in a variable. EG:
Public Class Test<br />
Private _myType As System.Type = MyCustomClassHere.GetType()<br />
<br />
Public Sub DoSomething()<br />
<br />
Dim MyVariable As (Here it would refer to _myType to get the data type [which is MyCustomClassHere's Type])<br />
<br />
End Sub<br />
<br />
I've tried using DirectCast(), Converter(Of Object, Of _myType) and alsorts but I can't get it to work. Could anyone help me out? Thanks.

If I get what you're asking, I'm sorry to say that you've been wasting your time. This won't work at all since the compiler needs to know what the type is at compile-time. The best you're going to be able to do is define it as Object, but then you lose all ability call methods and st properties on the object.

Why? Can you tell us why you are trying to do so? What are you trying to accomplish? We can then provide you either with a resolution to your problem or provide you with alternatives.
Sometimes when something does not work, change your strategy instead of trying over and over and wasting your time.

Hello!
My aim is to read inputs from a gamepad that is attached to an usb port. How can I do that in Vb.Net? HOw can I also check the device capabilities?
Thank You!

You'll have to use DirectInput in the DirectX library to do this. There is nothing in the .NET Base Class Library that will do this for you.

I've never used it myself, but I know there's some support for hardware in the Robotics Studio Microsoft put out. No guarantees, but if you're determined to stick with VB that might be a starting point.

levelnumber: course1

Merging cells is not supported. You'll have to use a third party grid control to do this, like DevExpress's XtraGrid Suite[^].

--> indexof and lastindexof methods get the occurence from the start and from the end. So, how will i get the character in the middle..?
For example:
"adfdfafwera"
how will i get the mid "a"?

--> Do you think it will work. I don't. Coz everytime it will not be the case....... just take the example and try it..
"afeafsdfwerwa"
--> i want to extract the 2nd "a". How..?

hi nasir,
if you want to extract second occurance then you can try something like that
Dim str As String<br />
str = yourStringVariableValue<br />
Dim FirstLocation As Integer<br />
FirstLocation = str.IndexOf("a")<br />
str = str.Substring(FirstLocation + 1)<br />
Dim SecondLocation As Integer<br />
SecondLocation = str.IndexOf("a")<br />
SecondLocation = SecondLocation + FirstLocation + 1<br />
MsgBox(SecondLocation)
hope this helps

You can use the IndexOf method of the String class to find the index of the first occurance of your string. Then you can call it again, passing in the position to start the search from, namely the position of the previous occurance of the string.
' Look for the first occurance of "a" in a string
Dim pos As Integer = SomeString.IndexOf("a"c)
' Look for the next occurance of "a", starting at the position of the first occurance +1.
Dim pos2 As Integer = SomeString.IndexOf("a"c, pos + 1)
Or, if you already know the positions, you can use the SubString method of the String class.

Not with this project. There's way too much possiility for abuse (keyloggers). There are other ways to monitor users without resorting to standing directly over their shoulders.
