I am very new to programming so sorry for the simple question, but I am at a lose. What the program needs to do is take a user defined starting and ending range, and then build a table based on that range. Inside the table each record will need to have two check boxes.
So for example the user enters in a starting of ABC01 and ending ABC03 and clicks the button the table is populated like this;

I'm converting a user generated list box to an array and then generating a user defined number of random strings and placing it in a textbox.The code I have works fine as it will generate the number of random strings the user wants, except sometimes a line is blank at the top of the list but is counted as a string.

I was knowing that For Each loop can only be applied to those classes that implement IEnumerable interface . But recently i accidentally wrote a code that is using For Each on my class's objects collection and my that class is not implementing IEnumerable interface .Below is the sample code that i am testing on :
Sub Main()
Dim personList() As Person = New Person(2) {}
personList(0) = New Person("s1", "s2")

I have the following Query:
SELECT *
FROM tbl_Muffins
WHERE OvenLoadId IN (
SELECT OvenLoadId
[code]....
The idea of the query is that I want to specify an OrderId, and I want all Oven Loads that have items from that order in them, as well as ALL OTHER ITEMS in those loads, even though they could be from other orders.The query works as expected, but I'm not able to use it for my Crystal Report I've written it for.I have put this query into a User Defined Function, however I'm unable to use a call to that function as a table source in my Crystal Report. I am using Visual Studio 2003 (I know it is old, the client refuses to upgrade).

I'm using a Datagridview to fetch information from an XML. Each row contains a separate entry. I can read from and append to the XML database, but I want to:
A) Be able to save any edits made in the database to an XML file.
B) Store and fetch a collection of possible variables to populate a list box.
A should be relatively easy, but I don't know if B is. The XML database will contain hex values that can be written to predefined offsets, and each could be any number of bytes long. So one entry in the XML/Datagridview database could read "00,0A,0B,0C", where commas separate available write values, with each possible value being another line in a listbox. When a value is picked from the listbox it will be written to the XML.
I don't want to have to make <ListBoxValue1>, <ListBoxValue1> in the XML for each possible entry, so I'm hoping there's a more efficient way.
If you're interested in what I'm making, it's a hex editor that loads descriptions of offsets from an XML, then loads the values for each offset from a file. Here's a screenshot.
I feel quite silly asking this, but I couldn't find a definite answer anywhere. in vb.net, how are the array elements defined (if they are defined) for, for example:
Dim myarray(5) as int
does, at this point in time, myarray(3) for example have a defined value? If so, what is it?

I'm creating a tool using windows form which needs to retrieve data from an Oracle database configured to use odp.net using an Oracle Stored Procedure. I'm planning to use the code below for some basic testing.

I am a less-than-intermediate programmer who has done most of his work in VB6, and now trying to wrap my mind around the new concepts of the NET languages.In VB 2010, I have a Structure called "Direction", with one data member -- an integer named "Value".

Is there a way to create a user-defined ImageList? I would like the user to be able to assign images to ImageList that would be stored for use in future sessions.
View 3 RepliesWell I had a thread going that branched out to this topic, so rather completely veering off the main topic there, I felt creating a new thread was adequate.So as the title says, I'm trying to create a user-defined type. It's not a simple type at that but a user here had showed me a way to fix all my problems. That was to create a type BigDecimal. Which my initial thought was to utilize the BigInteger type. Being that the Integer Part, and Fractional parts would be split off into two variables, both BigIntegers. Which would be combined at the end as a "decimal". However I have many many questions see that this is my first attempt at truly creating a type of my own. So as of right now I'm basically swinging in the dark here.

I have a database of 7 items that I want the user to be able to choose the order in which each is listed for use further along in programming. I'm thinking of using combboxes bound to the database. I found out that each combobox will have to have its own dataset otherwise they will all show whatever the current one that has focus changes to. Is there an easier way to be able to do this or is having 7 datasets bound to the comboboxes the best way? For this purpose I don't need all the contents listed in a DGV, only need the component name for now if this helps. Database programming is new to me and I'm a hobbyist programmer from VB6 days making the transition.
