Combo Box Read Write MySQL?

Feb 25, 2009

for starters not sure if this is the right place for the post considering that it includes MySQL and VB, its here.I'm trying to load data from one table into a combo box as the data you can select, this i have been able to do "tbl_Wind" using "WindDirID" and "WindDir"

also, I am trying to select (if it exists) a value from "tbl_date" "WindDirID" to select a value from the existing data in the combo box loaded from "tbl_wind"and finally, I want to be able to change the value in the "tbl_Date" depending on if a value is selected in the combo box.when a new record is created in tbl_date it uses default values, so there is always something in the field.below is about how far i got, and its the only part that works (extracted and edited of course to exclude the other queries)

VB2005 MySQL Read() - NullReferenceException Error

Jan 28, 2009

I have a somewhat weird problem with a program i'am writing in VB2005. When I debug the program and start 1 backgroundworker (got 8 different backgroundworkers in the program) in VB2005 nothing goes wrong, but when i'm starting 2 or more backgroundworkers I get an NullReferenceException when trying to read from a MySQL database (withing a few minutes in debugging). This error isn't always in the same backgroundworker, but is always in the same block of code in a backgroundworker (1 of 8). I tried different approaches in getting the results I need, for example with read1.HasRows(), but this also didn't workt... the MySQL table doesn't also seem to be the problem.

Line 8 is where I get the error (read1.Read())... This is a snippet from backgroundworker1, but is also randomly happens in the other 8 backgroundworkers as well... When I'am trying to read te content of read1 is says "Nothing" when the error occures...

VS 02/03 Xml Read & Write?

Dec 21, 2010

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)
InvoiceWriter.Formatting = Formatting.Indented 'Set formatting of XML file
