Again, WMI. You're looking for Win32_SystemDriver objects.

Either Google for it or have someone write it for you at RentACoder.com. Noone here is going to write it for you.

The .NET Framework doesn't have anything that will do this for you.

You either have to have an understanding of how Windows interacts with devices and write the enumeration code yourself, P/Invoking the required functions.

Or, use WMI to to enumerate through the devices. You're looking for objects of the WMI class Win32_USBControlerDevice. Google that class name for examples.

The method you choose depends on the what you want to do after you enumerate the devices.

Look at the three articles written by Tom John here on CP about treeview controls. His first on persisting treeviews should answer your question.

Do or not do. There is no try.

Looping through a string array

j45mw23-Dec-05 12:22

Can someone tell me how to loop through a string array using a FOR..NEXT or DO UNTIL loop?

Public Sub Update(ByVal Product_Category As String, ByVal Percentage As Decimal, ByVal ParamArray Location_Codes() As String)

End sub

The above is my subroutine and I want to loop through the ParamArray Location_Codes(). So that I can then run some additional code for each item in that array.

Kinda like this:

For each XXXX in Location_codes()
Make some decisions
Next

Can this be done?

Thanks

You can loop through using the Chars method:

Dim thisstring As String = "abc"
For i As Integer = 0 To thisstring.Length
MsgBox(thisstring.Chars(i))
Next

In VB 2005, you can omit the ".Chars":
For i As Integer = 0 To thisstring.Length
MsgBox(thisstring(i))
Next

Ack - that should be "thisstring.Length - 1" of course.

Public Sub Update(ByVal Product_Category As String, ByVal Percentage As Decimal, ByVal ParamArray Location_Codes() As String)<br />
<br />
For Each code As String In Location_codes()<br />
'Make some decisions<br />
Next<br />
<br />
End sub

You may have to do some error checking first, to see if Location_Codes is not nothing or empty.

Help! Changing the screen resolution crops the forms background image

Hello!

I have a problem in my application that occurs after screen resolution changes. It crops the background image of the form. So the form's background image looks cropped after change from (800 x 640) to (1024 to 768). I have developed application for (1024 x 768) screen format.

Any idea how can I solve the problem!

Thanks!

I'm assuming .NET 1.1...

You'll have to resize the image your using for the background yourself. You can do this by drawing the background image yourself in the OnPaint event of the form. Use the ClientSize property of the form to determine the correct size. This will also work if the user grabs a side or corner of the form and resizes it to something smaller than the screen dimensions.

how to automatically notify user when database finds a match?

nidhelp22-Dec-05 22:30

Hi,

I would like to design an application to allow shoppers to check if the stocks they have in mind have arrived in a stall.
I have to use a modem which acts as the stall's SMS center and use SMS to test the program. To find out availability of stocks, the user will have to SMS to the SMS centre to specify stocks details such as:

• Model / Type
• Quantity
• Size
• Colour

Customers just have to wait for the SMS centre to notify them that the stocks have arrived. Their specified stock requests as well as their contact details are automatically stored in the database system. Staff will update the database when new stocks have arrived and the consumers will be untomatically notified once the database finds a match between customers’ request and stocks’ availability.

Customers can also easily change their requests at any time through the use of SMS.

How do i start to put this idea into codes?
Thank you!
