Why? So you can take 10 times longer to write your app? Do you have any idea how USB works? How to enumerate devices on the bus, select a device, communicate with another host on the bus? This is very specialized stuff and there is not alot of documentation out there on how to do it. You won't find any code in VB.NET that show you how to do this.
You're re-inventing the wheel when you don't have to...

Usually comes with the cable you need...

Comes with the cable!

Read the documentation that comes with the cable!

No. Like I said before, it works just like any other TCP/IP network. Your Serial Comm experience won't help you.
Sushmadm wrote: Will the driver software be flexible like an activex control?.
How should I know? I've never done this before. The information you're getting is from the small amount of YOUR homework I've done!
Sushmadm wrote: Hand Held Controller.Please do help me with this,
Like I said, no experience with it. This part will depend HEAVILY on your device and your application on it.
Look, you're going to have to do your own homework on this. What your doing is rarely done and adding a "handheld device" to this will further restrict the help you get from anyone because of the VERY specialized nature of what your trying to do.
If you don't already understand TCP/IP networking, if your device and application even support this, start picking up some books on it. You're most definately going to need them.

Hi Dave,
Thanks so much for all ur suggestions. I have baught a USB cable which comes along with a driver.The driver after installed creates a COM port for USB port as soon as the USB cable is plugged in.Hence i can access the USB port just like a com port. It made my job very easy!
Thanx again,
Sushma

want code for sending SMS from PC to mobile phone...
help me..
Regords,

Its not that simple. You will need an account with an sms portal service. They will normally have examples and api's to enable you to do this. Your best bet is to google for some probably in the country you ware wanting to service.

I'm having trouble finding a way to selecting a control and drag it to another location on the form when the program is running (not the design mode). Same thing is true for resizing a control with the mouse during runtime.
I could do this in VB6 but the method to do it in VB 2005 seems to elude me and I haven't been able to find any references on how to do this.
I would appreciate any help on this.

I am new to Nhibernate. I need to change my asp.net project to incorporate Nhibernate instead of ADO.net.
I am unable to replace the SqlAdapter and the dataset code.
The code is --:
da = New SqlDataAdapter("select * from DBR where 0=1", MyConn)
Cb = New SqlCommandBuilder(da)
da = Cb.DataAdapter
da.Fill(ds, "DBR")
ds = Dtset.IterateThroughChildren(parent, ds)
da.Update(ds, "DBR")
I have the class for DBR table, but can any one tell tell how to do bulk updates or replace the above code to nhibernate code.

You'd probably get a better response by posting your question on the Nhibernate SourceForge board. There a literly thousands of libraries and controls out there. The chances that someone who has used Nhibernate will see your post here are very, very slim.

You'll probably get a better response in the Embedded/Mobile Forum[^].

thanks for that suggestion, it helped to know more about printing.
But it doesnot say anything about how to use no of pages selection (ie. FROM PAGE, TO PAGE) . I have enabled the print dialog and also the selection but was not able to print the specified pages even if i told to print (EXAMPLE FROM PAGE 1 : TO 2 PAGE), instead its prints all.
Thanks again

Hello,
I have a datagrid with a bound datatable. I want to edit one or two columns of the data. When I set the readonly property of the datagrid to false then I have row to add new data, and this is not allowed.
Also after the inpu of the data I have to calculate a value for another column in the grid.
Datagrid = Code, Description, Price excl tax, Tax (%), Price incl Tax.
So when the user changes the price excl then I have to calculate and show the price incl (depending on the tax) or if the price incl is changed then I want to show the calculated price excl.
I'm still working with VB.NET 2002

Hope these links help. I'm not sure if they are specific to .Net 2002 or 2003.
