In VB.Net for an ASP project I was able to do the following:
Dim Item As ListItem While DataReader.Read Item = New ListItem Item.Text = DataReader.Item("CustomerName").ToString Item.Value = DataReader.Item("CustomerNumber").ToString Me.lstCustomers.Items.Add(Item) End While
However in a VB.Net Windows Project it won't let me duplicate this.
I need to display the CustomerName but return the CustomerNumber of the selected customer
I am also adding the items in code because they are changing based on changing values.

I created some custom controls which I use quite often and I thought if I add them once to my ToolBox they just will be there next time I start up VS2008; however, that does not seem to be the case! Each time I start VS2008 I have to re-add that controls (which is quite annoying!). Is there a trick / way of having them there permanently?

I have created multiple dropdown list at runtime and populated with data. I also have added an eventhandler to determine the selected value of the drop down list.
The code is as follows :
Dim tbl As New Table()

I have two table called
1.Register product table
2.Sell product table
Register product table consist of (Product Id (txtProdId.text) and Product Name(txtProdName.text)) NB. All are textboxes Sell product table consist of (Product Name(cboProdName.text) and ProdPrice (txtProdCost.text)). NB. ProductName over here is a combobox.
When someone saves record in the Register product table, items should be added into the combobox into Sell product table.

I want to get all items from one column of database table to the combobox items.

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 have a form in my vb.net application used to take the data about the returned stock. The form contains two comboboxes. One, named combobox5, contains invoice numbers and the other, named combobox3, contains party codes. Both the comboboxes are pre_loaded using sqldataadapter.
Now what i want is to change the party code in combobox3 when the invoice number is changed in combobox5. Elaborating it further, When Stock is issued the party code is stored along with the invoice number to keep track of to which party was the stock issued. Now when stock is returned i want to keep track that which party has returned the stock and i want that the party code should be automatically selected when the invoice number is changed and it should be what is stored in the database against that particular invoice number....
I'm using the following code for doing so:
Private Sub ComboBox5_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBox5.SelectedIndexChanged

Dim con As New SqlConnection("Data Source=TAHA;Initial Catalog=ADT;Integrated Security=True")

This question is about VB.NET. I'm quite a novice on this one, so please forgive me if you feel that this question is nothing short of crazy or whatever. Anyway, I've been a creating a simple Windows addressbook Form application. We all know for a fact that a single person can have one or more addresses, of which a one-to-many relationship holds true. So there, my application also has to be able to edit each of these addresses (by the way, my application uses an Access Database, which really sucks but it's part of my task), and I already thought of using a control array (just like in PHP but it obviously never worked in .NET) for me to edit them. How am I supposed to implement this?
View 3 RepliesI have some questions on AppSettings. I can add a setting at design time from the settings tab of the My Project. I would like to add to the settings at run time. I have not found a way to do this. I would in VB6 use an ini file but would like to start using xml.
The .net makes this folder for the settings C:UsersRyanAppDataLocalTestAppSettingsAppSettings.vshost.exe_Url _0ay3fimqt4k0pp1s2e4vb3pi3iymxzx2 .
How do I retrieve the location to add to the xml file?
I want to place a few buttons on my form. The number is unknown at design time. Actually each button will represent an item entered in combo box. So if user adds an item, a button on the form should be added by the code.

View 10 RepliesI have added a DataGridViewComboBox to my DataGridView during design time. It has 0 items in it and I need to add a bunch of items to it during runtime.
In most controls, they have some kind of direct method like ".Items.Add("etc")", but for the life of me, I can't figure out how to access the DataGridViewColumn programmatically.
I can create a new ComboBox during runtime and add it to the DataGridView, but that's not what I need to do.
I played around with IntelliSense, I've searched on Google and I've looked through the documentation. The only thing I could find on MSDN was DataGridViewControlCollection, but I didn't see anything that would allow me to directly access that control.

In the helpfiles of Visual Studio 2008 I read control arrays are no longer supported. There is an example for the new situation but then you need to hard code the names of all the controls beforehand.I do not know how many controls I need, could be one or 5000 (think simple image browser). Is it still possible to create something like that or should I change to a different programming language like Phyton? At the moment I work around it by using a browser control and then manipulate the <img> tags but I'm puzzeld as to why this functionality was removed and if there's a solution to the problem.Another thing I don't understand is where the app goes when it's installed with 'Click once'. It dissappears completely, doesn't show up in 'Program Files', can not be found by the search function but it *is* somewhere because you can start it form the Start menu. However, I use data which is in a subfolder of the program folder, which I nor my program can find any more after the app is installed. The program runs but it can't find any place to put/get its data so in the end it doesn't work.
I work around it by *not* installing the program but have people just run it after unpacking the downloaded folder. This works great but I wonder how long this will be the case until Microsoft disables this possibility? I have no idea why they would, but I also have no idea why they did remove the functionality I mentioned above. I already changed to PHP and MySQL because I had to throw away my carefully built W2K+MSAccess image database a few years ago and after installing Vista Visual Studio 2005 was a goner. OK, I upgraded but then no control arrays any more and now they hide the apps when you install them? Why on earth would they do that?
