I'm trying to build a new customer data entry page for a db project. One of the features I would like to add is a way to check and see if there have been any new records that have been added that haven't been explicitly saved to the db. If so, when the form_closing events fires I want to evaluate whether or not new entries have been made that weren't saved, and then count the number of rows that haven't been saved.
I've read about @@Identity. I've also read that it's no longer supported. I get lost in the mountains of data searching provides.I'd like to get the "ID" field, which is an AutoNumber Primary Key field, when I insert a new record. There's got to be a simple way.
I've created a database in Access 2007 and connected it to Visual Basic 2008. My database have tables Coachee and Coach. Details of Coachee are displayed in one form and there's a button that when clicked will show details of the Coach of that particular Coachee in a another form. If the Coach is not in database, user will be prompt to insert a new Coach record. Problem is, when saved, the newly inserted record will not be displayed and i have to exit and rerun the program, only then the record will be displayed.
just want to ask help in terms of adding new menu item onclick event on an existing menu item.

My question is how can i add an onclick event for this newly added menu item?
I am using Visual Studio 2005 (Visual Basic) and MS Access 2003 I am trying to build an application in the lines of the book "Doing Objects in Visual Basic 2005" by Deborah Kurata. So, I have a Data Access Layer (DAL) Class Library that is separated from the business logic layer (business objects) Class Library. I try to add a new business object such as a "Customer" to the Access Database, where the "Customer" table has a PrimaryKey "CustomerID" which is an AutoNumber field. I am successful in writing the values to the database, but I can't figure out how to know the "CustomerID" of a newly added "Customer" so I can populate the business object with the respective values.
if could modify the following code for me so that it save data row by row from a DataGridView into SQl Server. Currently, the code saves data from all rows at time instead of saving only the recently added data in a row or rows when the user clicks a button.[code]...
How can I save ALL of the items in a listview, items that were added by the user? I tried application Settings and tried creating a settings file but there is not a settings option for listview items.
I am having a problem with adding a record to a customer table in a Microsoft Access database. I have worked for hours reading my textbook and troubleshooting to no avail. The copy and paste below from VS is a little messy. When I execute this code below the record is not added and I do not get an error of any type. When I go into debug mode, all of the parameters are correct and everything looks good. If I open up Access I can manually add the record but using my program nothing happens. All datatypes are string in VS and text in Access.
First an instance of the Customer Class is created and this seems to be successful. But when I take that customer object and run the AddCustomer method of the customer class it is not successful in that the database does not reflect that the record was ever added. [Code]

how to use #ZipLib. I've tried there forum and I've looked on this and other sites . I'm still new to VB and trying to teach myself. Using items like a text box are easy but i don't know much about how to use added items such as #ZipLib. Examples of compress and decompress would be wonderful but if you show me what can that would be great too.
I am using VB.NET together with ADO.NET to create a program. I have set my TableAdapters as needed and bound the correct tables-columns to my comboboxes.My problem though is this:My combobox2 item is bound to a datatable. The table adapter's Fill method (the select command basicaly) includes a public variable in the where clause to fetch the correct results. I ll put some code here to clarify it a bit more.Public Class Frm_inv
I'm using VB.NET 2010 When I try to add the items from a listbox to a textbox, I get a strange combination at the beginning of the textbox, but if I read further, the actual combination that I want is at the end.
So let's say I have 3 integers in my Listbox like: 01 02 03 And I want these three items to be in the Textbox like this: 01 - 02 - 03
I had a functioning datagridview that was created from VB2010's datasource by clicking on a table, picking datagridview and dragging to a form. I changed three of the columns of the grid to comboboxes bound to different tables. If I change a value in a column (not a combobox column which still shows the value from the original table), I receive InvalidOperationException was unhandled on Me.TableAdapterManager.UpdateAll(Me.MasterDataDataSet). What code do I need to add if I change columns to comboboxes?
I have a ComboBox control with some items added to the items collection in design mode. What I want is when an item is picked from the ComboBox a different value is actually used in the code, instead of what is displayed. I am aware of the DisplayMember & ValueMember properties, but I'm not sure if that is what I need to use. All the examples I found were for bound data.
I've created a custom control that I insert into my window with the following code Code: <controls:ListExpander Text="Class Diagrams"></controls:ListExpander> The control in question contains several subcontrols, among others, a list. How can create the setup, so I can specify items that should be added to the list?
In which case the SomeItem objects should be added to the list in the ListExpander: Code: <ListBox Name="lstItems" Background="LightGray"> <ListBox.Items> // Items should go here </ListBox.Items> </ListBox> I'm quite new to WPF, but I suppose it's something along the lines of creating a dependency collection on ListExpander that takes object of the type SomeItem? I simply want to be able to give the control a few arguments which it can translate into items in the listbox contained within the the control.
I'm making a combobox on a form. I want the combobox to have a list of choices from a table in a db. The two columns are a String and a Date. I want the date column to only show the year. I'm hoping I have the code right as it is above, but I'm not positive I've done the whole date thing right.
I do not have any code to show, but using asp.net, vb.net, and SQL with stored procedures.If on a page I have an item that is added to the database and therefore that information is "saved", is there a way to have an ("exit without saving") button on the page that does away with those changes?Using infragisitcs ultrawebgrid, you add an item to one table. You can add an item to another table on that page. i assume adding these items to the table automatically saves in the database. There is also a text box but without clicking save I do not believe that those items are actually added to the database. Update panel is used, I don't know if that matters.
If after someone adds to the table but then decides.. oh wait.. I don't want to do this just yet, is there a "one-click" way to act as if I never visited that page to add info? I'm assuming it would be deleting the entries but this would have to be limited to deleting ONLY those items added while making... we don't want people adding info, then going back and deleting once the "save" button has been pushed.
I am using VB.NET in VS10. After I add items to a list box I'd like it to scroll down so that the most recent items are visible. I tried this with no luck: StatusListBox.SelectedItem = StatusListBox.Items.Count - 1 How to make the box always display the most recently added items?
