I want it to add the correct answers the student got out of 10 flags.

I have a problem with a combobox. I have a form (with information about clients) with textboxes binded to a dataview. One of the columns in the dataview contains a number that tells me what kind of client it is. I don't my users want that my users have to fill in a number in a textbox, but I want them to choose a item from a combobox. De selected value should be the value that is actually saved in the database.
This is my
Dim cmd As New SqlCommand
Dim dr As SqlDataReader
VerbindingMaken()
cmd.Connection = cnnVraagbaak
cmd.CommandType = CommandType.StoredProcedure
[Code] .....
De Datasource is the information in my combobox. With Databindings I'm trying to bind it to my dataset (or view, that doesn't work either) with clients. Every time I get a NullReferenceExeption. The moment I remove the line cbo.DataSource = dsRelatie.Tables("Relatiesoort"), I don't get an error, but it doesn't work either.
That dataset is filled (I've checked) and also the derived view. The column Relatiesoort exists. What do I have to do to make it possible for my users to choose an item from a combobox and save the selected value to the underlying dataset?
the below statment is right 100% but what i need is to change the word mobinil when the user choose another item from the combobox
cmd.CommandText = "select * from warehouse where mobinil ='" + ComboBox2.Text + "'".I thought that i can do the follwoing dim x as string x= here will be the item selected by user- and ofcourse i need it to be put instead of the word Mobinil
cmd.CommandText =
"select * from warehouse where x value ='" + ComboBox2.Text + "'" is that possible ?
as in VB2008 the documentation suggest creating a module or class, then selecting 'Export Template' on the File menu. Regrettably my file menu does not show the item 'Export Template' in my installation of Visual Studio 2010 Beta 2.

I have a weird question and I honestly hope you understand what is happening here: I design my form (using VB.NET) and put on it a few textboxes, comboboxes and a listview. After the design, I want to adjust the TabIndexes for each control on the form. On the right-hand side of the interface is the property box.
I then select the 'TabIndex' property item and enter a number key (for instance 0) for that selected item. I then select the next textbox control and enter the next number (for instance 1) WITHOUT re-selecting the 'TabIndex' property item. As soon as I select the combobox or listview control, the currently selected property item jumps to 'Items' or 'Collections' and does NOT remain on the 'TabIndex' property item. Why is this happening? Everything worked fine and all of a sudden this starts happening. Should I reset the editor settings or how can I resolve this matter?

My project is a christmas edition and the goal is not to get money or something, since I will not add it... Erhmm... Let me get to the point. I have already designed a layout and scripted some things. I have about thirty questions but I do not want them to always spawn in the same array, if you know what I mean. I want the program to randomly choose one of those thirty questions and NEVER choose the same question in the same program run. By the way, there are four options on my project: A, B, C and D. I have got everything, I just need a code.

I have an application that is primarily developed on an x86 machine. I recently checked the app out of TFS onto a Win 7 x64 machine for development. However, every single form level resource file shows up in the error list with an entry like the following:
is not a valid Win32 application. (Exception from HRESULT: 0x800700C1) Line 127, position 5. C:Users...shortened...FormsfrmCustomer.resx Line 127 Column 5
What I find interesting is that my application level resource files aren't showing the same error. Plus, these are just XML files. They aren't applications in any way.
I'm currently working under VB2010 beta 2 on both machines. Obviously, with a bunch of errors, the app won't compile on the x64 machine.
