1. I am trying to sum up a record in ListView1 called NumberInStock and have that value added to a text box called txtInventoryTotal. I have been playing with code to do this and have come with something that is placing a result in my text box. The problem is that it is the wrong answer.
On my first attempt, I went through and created a new function called InventoryTotals() that calculates the sum of the NumberInStock but couldn't get it to display in the text box.
2. In ListView2, I want to show a location and then have the NumberInStock show a subtotal for what is available per location. How do I go about doing this? Do I have to create a connection to the database every time I want to accomplish this? Right now, doing that causes errors in Vs 2005. If i have more than one connection trying to access my database, it tells me that it cannot establish a connection to the database.
I have added a screenshot of my application in hopes that it gives you an idea of what it is I am trying to do.

I have two forms. On the first I have a datagridview that is filled with records on the form's load event. When the user double clicks on one cell of the selected row (of the datagridview) I want to open the second form and fill the textboxes with the equivalent data (I mean each textbox must be filled with the equivalent value of the selected record).
I want to be able to get the one record I return from a table and put the results into text box's directly rather than put the result into a combo box and then transfer the text across.
Private Sub GetStationStats() conn.ConnectionString = myConnString Dim myCommandStationStats As New MySqlCommand Dim myAdapterStationStats As New MySqlDataAdapter Dim myDataStationStats As New DataTable Dim SQLStationStats As String [Code] .....
The fields Signon and SignOff, plus many others which I didn't include in this sub. Above code does work, its how to get it into a text box.....
I have a LINQ to SQL DataContext with all my tables and all my stored procedures in it. Let me first start off by saying that we are upgrading our project from an access project to a WPF project. So in the Access project you could set a forms datasource to a stored procedure and edit and add new information. So in my WPF project on the page load I call my stored procedure to return an ISingleResult and then call a function to set the binding on every single textbox on the form. One is there an easier way to do this and two what if I want to add a new record since the textbox's are binded to an ISingleResult?

I have sucessfully written in excel VBA. The idea is to used the textbox1_change event to find a match in column A of table and once it finds the record, return the value of column B as label1.text. [code] In VB 2008 it's a lot different. I have set up the form the same way with the textbox and labels. I have made a dataset with (1) table (Table1) with (2) columns. Lets call them column A and Column B.I have added the dataset as a binding source to the form and also a table adapter. I also have a standardized query made for the dataset with a very simple SQL statement "SELECT Column A, Column B from Table1"..In order to get the user input to start searching Column A I assume under the textbox_change event i would put something like: [code] I'm getting a bunch of errors of course. Would somepne be able to give me some direction?
How do I force users to save the current record (if current record has changed) and not let user go to the next record unless the save button is pressed?
I'm using something call ultragrid in my program.The program works as a mini-record keeping area (Like any datagrid, really). Well, I am adding a history to it and it allows the user to see the last 50 records searched. They get a grid showing the records. This, thus far, works perfectly What I want to do is this: I want to select a record (A cell) in the column 'Dog and have the text of that cell appear in a textbox. This is what I've tried with no success.
HTML Private Sub HistoryTextBox_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles HistoryTextBox.TextChanged If ugHistoryButton.ActiveRow.Cells("Dog").Selected = True Then
[code]....
It just doesn't seem to want to transfer over when I select the cell in the 'Dog' column.
While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.
I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:
' Copy Product/Categories For Each oneProdCategory In OriginalProduct.Categories Dim relatedCategory = _productContext.GetObjectByKey(New EntityKey ("ProductInfoEntities.Categories", "RecordId", oneProdCategory.RecordId))
