Store DataGridView Value Changes
Apr 9, 2012
I have a datagridview that is populated from a collection of queries. This collection is fed from a xml file. I have the datagrid populating fine with new rows and correctly displaying the parameters of each query based on which query is selected. My next goal is to make it where when the user edits values of existing rows, when the save button is pressed those changes will simply go and update those values in the xml file from which they are originally pulled from.[code]

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()
End Sub

I experience some difficulties with property Item of DataGridView component.
The application is made in Visual Basic 2008 Express Edition and I'm using Sql Server Management Studio as DBMS.
I have made a query starting from my tables and I want to add the result of query in a datagridview in reference with what the user selects: (I have 3 textboxes and 2 datetimepickers).
Here's the code in button search:
(don't know how to add the 5 components in the dategridview and integrate the query in datagridview).
My form is this:
Here's the full code of search button:(where I have problems) (I made a reader to read my query and I need to store the result of query in a datagridview related with what user types in the 3 textboxes and selects from the 2 datetimepickers.)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim conexiune As SqlConnection 'for connection with sql server

I want to make a search form the user completes the 3 textboxes and 2 datetimepickers. (so five components).
Also I have a button called search and a datagridview.
When the user presses the search button it searches into those 2 tables (depending on what user typed in the 3 textboxes and selected on 2 datetimepickers).
Example of search:
The user searches like this:
When it presses the search button the results will be stored in datagridview(first textbox is the field DB-20-RTS from table PatrimoniuMasini and the rest are fields from the specified columns (name of labels) from the second table FoaieParcursMasina -is the second row from this second table).
Here's the code in my search button (don't know how I can store the 5 things(2 datetimepickers and 3 textboxes in the DataGridView) . My problem is in understanding the property item of DataGridView(DataGridView1):
DataGridView1.Item(row_index,column_index) -general syntax
Here's the full code of button search:
Dim conexiune As SqlConnection 'conexiune cu sql server
Dim comandasql As SqlCommand 'cerere -interogare sql
Dim msg As String ' msg- variabila dk suntem conectati sau nu

I performed a search by completing this information in my form:
TextBox1: the user types DB-20-RTS
DateTimePicker1: selects 7 april 2004
DateTimePicker2: selects 7 april 2004
[Code]....
I don't have errors of syntax in my code the only problem is when I press the search button (it doesn't store me in the columns of datagridview the 5 things I want).

"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim obj1 As New Invoice(Val(TextBox1.Text))
TextBox1.Text &= obj1.Invoice1 & vbNewLine
TextBox1.Text &= obj1.Invoice2 & vbNewLine
TextBox1.Text &= obj1.Invoice3 & vbNewLine
TextBox1.Text &= obj1.Invoice4 & vbNewLine

I hope this is the correct place to obtain a little bit of advice for a program I am looking to produce in visual basic 2010.
I currently work as a design engineer designing press tools and a lot of our designs are similer just maybe a feature, length, diameter change etc. So the design principles are the same for each product.
What I am aiming to do is program the 3D design package so that 80% of the tool design can be done using the program etc.
Now the enquiry I have is where would the best place to hold the standard data be?
For instance each press has a maximum blank diameter, shutt height, bores diameters in the bed and likewise each product type has design features with the same calculations such as length, pierce etc.
I have done a bit of reading and I have found that data can be stored into text files, xml files and databases etc or hard coded into the program.
I am looking to allow new presses to be added so the user would need to add new shutt heuights, blank size etc but the tooling would have to be unqiue dependent on the typs of stage. So I am wondering to store this information would a database be the best option even though the data will not be continually updated more a place for it to be retrived from excpet under failry rare circumstances.

I have a VB.Net app that uses an MS Access 2003 Database. In my connection string, I'm utilizing the "|DATADIRECTORY|" construct (see code). cnn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DATADIRECTORY|MyDB.mdb;User Id=;Password=;"When I run my program, I'm getting the following error message:"Could not find file 'C:indebugMyDB.mdb'"
In order to use the "|DATADIRECTORY|", where do I need to put it within my Project. I basically want to deploy this app on stand-alone PC's. I guess a more simpler question would be: How do I deploy a single user application that uses an Access Database where the database location will go wherever the user specifies when installing the application?

I am using visual studio 2008, asp.net.vb.I have various functions; 1 that calculates totals, 1 that calculates averages, 1 that calculates percentages etc. The data they act upon is different depending on the particular web page, but all my pages use these functions. So I want to know how I can store these functions in a single place so that all of my web pages can access the routines. At the moment all I know how to do is to write seperate functions in the code-behind for each individual web page.
