I am trying to extend an application to to write the details from textboxes on a invoice form to an xml file.I have created 3 methods for my invoice class which will open the invoice xml document, write to it, and close it.The open Invoice method creates and invoice.xml file and writes a start tag named invoices.
The WriteInvoice method writes an invoice element for the invoice with attribute named customerName and three child elements named ordertotal, discounTotal and Invoice total. These values are taken from the textboxes form the form.
The CloseInvoice writes the end tag for the root element(invoices) and closes the file.
I have wriiten code for these methods but can only get the open invoice method to work.
My code for the 3 methods is shown below:
Public Sub OpenInvoices()
Dim sInvPath As String = "C:MurachBeginning VB.NETExercise startsVB.NETChapter 14InvoiceInvoices.xml"
Dim InvoiceWriter As New XmlTextWriter(sInvPath, Nothing)

How do I make the text in textboxC get displayed on the first line of textboxA and move all the other lines down the list?

My first question has to do with the opening lines needed in a VB program in order to connect to Excel 2007 and read/write some data from/to it. I know the process only slightly and reading and writing to the cells is not my real concern for the moment. What I need to become familliar with are the lines like this:
CODE:
This is just one of the examples I have read through and to be honest I only follow this slightly. The trouble was that with each new article I read, people did this differently, not the variables on the left mind you, just that some left out lines, which I can see could be done based on circumstances. Still others said the Imports line was not needed....etc...and other loaded up at least 3 or four more Imports lines insisting all were needed.
I'm looking for some straight-forward advice on what is the minimum needed to access an existing Excel spreadhseet and to just read some of it's cells to variables in the code and then writed some data back to certain cells within the spreadsheet and then save and close it.
Also, please note that I am using VB 2010 Express. Why, because I'm a broke developer who spent most of last year out of work. I have a new contract assignment which is so far going well but will go even better if I can master this technique with VB.NET, not VBA. And all the docs I've read said that even though VB 2010 Express is a watered down version of VS, I should be able to do medium level tasks such as this with it.
Trying to emulate a typing application that when typing data in a WPF form, the info gets transferred to another application, such as notepad, word, etc. My first attempt involved using the .Sendkeys method but it doesn't seem to be repeatable 100% of the time. I initially had a button that when pressed would transfer data from a WPF app field to an open notepad app. Again, if I pressed it several times in a row, it would be hit or miss. It's like it hangs up and then after enough time, I try again and it works. I really need it to be 100%. Is there a fix for this method or should I take on a different approach? It would be ideal if I could go from notepad, word, etc. back to the WPF form as well, but I thought I would get one way working first.
