In the form, I have 6 textbox and a combobox. What I am doing is that when the form is run, the user have to insert the particulars in each of the textbox and select the items that have in the combobox and it will stored in the database.Here is the code that I am using. For the combobox, I am not quite sure so could anyone help me? What I mean is help me with the combobox part.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I am a beginer in vb.net. For a school project, i have chosen inventory control as the subject. WIth help from videos, i have developed some basic forms with adding/updating.
The product table design is like this:
Name Type Size
[Code]...
Now, i am designing the purchase/sales screens. I am showing the items name, qty, price in a datagrid. From the products table, I am able to select the 'ProductName' by giving it a combobox . I want the ProductSellingPrice also to appear in the next column of the grid.
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 ' defines a new connection to the database Dim con As New SqlConnection("Data Source=TAHA;Initial Catalog=ADT;Integrated Security=True")

basically i'm making a webbrowser, and i want it to select and option from a dropdown ComboBox, on a certain button click. I use this code which i found it on these forums as well:
For Each element As HtmlElement In WebBrowser1.Document.GetElementsByTagName("select") If element.GetAttribute("id") = "wrapper_opacity" element.SetAttribute("value", "51")[code].....
The problem with this code is that it just inputs the selected value, but it doesn't really SELECT it.The option selected is shown, but not activated.

In my Windows Form I have a ComboBox that is filled by a Stored Procedure with a list of names. I have the Combobox set for AutoComplete to "Suggest" and From "ListItems". When a user starts to type in and the AutoComplete does not find any matches in the listitems the user can tab out of the ComboBox and leave what they typed in the combobox even though it is not one of the Valid Items. Is there a way to check the Comboxbox to make sure of of the selected Items has been selected?
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
In my VB.net solution I have a form in which I have to choose a beginstation and an endstation. I have to select both from comboboxes. Now what I want is that when I choose a beginstation, the chosen station will be gone in the combobox of the endstation so that I can't pick the same endstation as the beginstation.Is there a way to do this? I've tried a lot with SQL and LINQ queries but it didn't work out :(
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'm having a problem with combo boxes. I usually use Java and it's been awhile since I used VB but I never remember having this much difficulty.My application is using an SDF file. From Data Sources, I drag the details on one of my Tables to my Form to get all of the fields. Three of them are comboboxes. Each of the three is an INT64 and each corresponds to a primary key in a different table. I click the tasks button on a combobox and for data source I select the appropriate table that has the data to go with the combobox, for display member I select the field that I want users to see, and for value member I select the primary key. Then I run a quick test and start the app, open the form, and add a new record. When I select a value from the combobox the selection won't validate because it doesn't think it's an INT64 like it should be. It seems to be using the display member as the actual value instead because if I change display member to the primary everything works great.

This is my ListView, Column 1 for ID and Column 2 for Notes I have a Multi-Line textbox and a Button Like this I want to load the selected note on the textbox when the button is clicked.How can I do this ?
So I have three listboxes, LB1 is an uploaded list, LB2 is a master list, and LB3 is generated from LB1 items that are NOT in LB2. I have a button that replaces the selected item from LB1 with the selected item from LB2, woot.Since LB3 is a subset of LB1, I want to be able to select the items from LB2 and LB3 and have it replace the item from LB1 but running into some trouble with finding the appropriate item without selecting it. [code] highlight Fred from LB1 and Freddy from LB2, click and Fred becomes Freddy in LB1. I want this same change to happen but by selecting the "Fred" located in LB3 (If LB1 is hundreds of names long, I don't want to have to sift through it and only make the changes that need to be made). [code]
I have 2 checkedlistbox on my form. I need to show the not selected items from first one in second one. User may select and deselect anytime so the second checkedlistbox should always shows the latest not selected items from the first one.
I am trying to use a checkedlistbox to tell how many of the items are selected. I can figure it out when I click a button. What I would like to happen is that when I check or uncheck the box I would like it to oupdate. Not wait until the index is changed. It would be nice if the checkedlistbox would throw an event when the spacebar is used to check and uncheck?

I just started dealing with XML files. I can already create an xml document that accepts data from a vb.net form (textBoxes, etc...) What I need to do is to open an already saved xml document and fill the respective fields in the form with data from the xml document. Tried using the xmlReader method, but that yields the entire xml document at once. How can I select certain elements from xml? Here is an example of my xml code:
I have a CheckBoxList where one of the options includes a textbox to fill in your own value.
