Per Combobox1 Show Combox2 Items With Database Connection?
May 17, 2012
I have added 2 Combobox on form. Combobox1 and Combobox2. I have connected databasetable to Combobox1.
i.e. Showing items of Combobox1 from database table column A.i.e. displayed one column of databasetable in Combobox1.Same way I have connected same databasetable but different column B to Combobox2.
So,What I am trying to do is :Once the form is set up for run then I click on Combox1 item Then I want Combox2 to display only the item of B column that is in the row of column A ( selected item in combobox1).
Is anyone able to understand my question here?If u have understood then do reply If my question is not understandable then let me know what part U din't understand so that I can elaborate

i am using access database for my program. now i have connected to the database in MDI form of main exe, and ir also works, user can log in, it gets verified etc etc etc. now here is the problem, when i load a form from dll and try to use any sql query on that form, i get message, "database connection is not opened". so what i did was, i added the connect() (a function i designed to connect to database) in the load part of the dll's form, it made the trick, query's started to run, everything went fine, and when i reload the form i.e after closing the form, i load it again from MDI form, i get error, connection already open..

Im currently doing a small programme of a register system. I need to add a new group box filed with a few textboxes and a couple comboboxes for each entry in a access 2010 database. for example if i had someone called bob in my database with his details i would like the GUI of the VB app to add in a new textbox for the name, a textbox for the address ect in a set order, this needs to work for multiple entry's so the textboxes ect don't overlap but be placed neatly below the added textbox.

I've used the same method to add items to a listview before but for some reason they're not showing, I even just tried a test:
Dim row As New ListViewItem
row.Text = "test"
row.SubItems.Add("test")
lstvwHistory.Items.Add(row)
in the load and that doesn't show up.Here is what I am trying:
gameDate = HistoryDS.Tables(0).Rows(0).Item("gameDate")
frmGameHistory.NewGroup(gameDate.ToShortDateString)
For Each row As DataRow In HistoryDS.Tables(0).Rows
[code]....
I walked through the code having a message box pop up every time an item was added with the count and it goes up as it should, nothing throws an error, and the item has all the correct parameters. I commented out the making a new group and just plain add the items and it still didn't show. I tried the lstView in all the kinds of views (detail, small icon, etc.)

I loaded up a checkedListBox with items from a .txt file. The .txt file has itemName, ItemPrice. Every item that gets checked shows up in a listBox on another form. The problem that I am having though is that I need to accumulate the itemPrices of the selected items to show up in a textBox, but the only price that shows up is the price of the item in the checkedListBox that has the focus. I have tried a few different things, but none of them seem to pan out. Any suggestions. I'll add the code to this so that you can get a better idea of what I am missing. I would really appreciate any help with this that I can get. Thank You for taking the time to read this. [Code]
