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")

I had added the items
1
2
3 to the combobox.
Then I gave the "Select" to the text of the combobox.
How can I able to reset combobox to select the text("Select").
I had tried by giving -1 to the SelectedIndex. But it gives only Empty.
This is for VB.NET Windows Application

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 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.

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 listbox that displays SSRS report names and a separate listbox for displaying email addresses. Both report names and email addresses reside in separate SQL tables. This application allows my users to select an SSRS report, report parameters, export method and email a URL link to one or multiple recipients. This part works very well. One particular report has 6 recipients and I have been trying to come up with a way to automatically select these 6 email addresses whenever this one report is selected but I haven't had any luck being the neophyte .Net programmer that I am.

I'm working on a program that will randomly select a loadout(weapon, perks, etc), but the user enters their current level to get the loadout. This is important because certain guns unlock at certain levels, so i don't want someone getting something they can't use.
I'm not sure what the best way of approaching this is. All i can think of is either getting a random item, checking if the user's level is high enough then if it's not high enough do it again.
