The difference is the scope of the object. A public object is accessible outside of the context in which it is declared - a private object is obviously the opposite, its not accessible outside the context in which it is declared. Basically if you want to access your function from another class...

I recommend that you experiment with threading. You can create threads easily: public sub work ' Add code to do the heavy work end sub public sub startwork dim t as new system.threading.thread(addressof me.work) t.start end sub In the "startwork" procedure a new thread is created to take care...

Why not use threading? Spawn a thread to take care of the work and display something on the form to indicate that it is busy until the thread is through.

My mistake, I missed out the datatable in my post before. eg. dataset.datatables(index).rows.count where index is the index of the datatable of interest - 0 if you only have one datatable

Oops, my apologies. SystemInformation.Network returns hardware information not connection information (it meets my uses for it but is not applicable to your question). I will right my wrong; here is a function that will do what you need (this is not my code, it comes from a post by Dean Slindee...

After the show event set the child forms location properties. eg. dim frm as new form1 frm.mdiparent=me frm.show frm.left=0 frm.top=0

Try this code in the child form: Dim frm As frmMDI frm = Me.mdiParent frm.Timer1.Enabled = True

Dim ico As New Icon("C:\myicon.ico") Me.Icon = ico

System.web.mail namespace Using the classes in this namespace you can create and send emails. You may need to design an email form if you want the user to view and have input to the email before it is sent. For example: dim msg as new MailMessage dim server as SmtpMail...

Access the file with a filestream and use the streamreader and streamwriter classes to read/write to it. For example dim fs as new filestream("C:\myfile.txt",filemode.open) dim sr as new streamreader(fs) dim firstline as string firstline=sr.readline

Create a new textbox and add it to the controls collection of the toolbar For example: dim txt as new textbox txt.text="my textbox" txt.left=48 txt.top=4 me.toolbar1.controls.add(txt)

It looks like you are using tabpage events. You need to use tabcontrol events: SelectedIndexChanged (for a changing tab pages) or Click (for a click event on the tab of the current tab page)
