I have the following XML Doc.[code]....
I need to accomplish the following:
when TYPE =CH and STATUS=LI then I need to get the values of REVIEW NUM and also the value of CHECK->ISSUE_DATE. here is what I have so far that is not working very well[code]......
This is my problem.I have a field set up in MS Access to Boolean YES/NO, this field is populated when the user check a checkbox on a windows form. If the user check a checkbox, the value is written as checked in the data field (MS Access).The problem is when I search for the user information, I need the information from the Data base to populate(return) to the windows form. Example: If I enter a users phone number and the user data is present, the form gets populated with the information the user previously entered which was store in the database.Example: If the user selected checkbox1 and submits the form. When I search for the user info, the check box should check(populate) because the user had checked it on submit.Here is what I have done:

I am getting the check value correctly in the database using a Boolean.Here is one of the errors I am getting. Unable to cast object of type
'System.Boolean' to type 'System.Windows.Forms.CheckBox.I am having trouble putting the codes in a code tag or block
I have a Boolean that writes to a data field. The data field(column) is set to YES/NO, if the user check a checkbox, the value is written as check in the data field.The problem is when I search for the user information, I need to get to form to the state it was in when the user submitted it.
Example: If the use select checkbox1 and submits the form. When I search the form, I need to make that particular check box check.

I have an application that I want to review existing word documents. What I mean by review is that they can look at them and print them and that is about it. I am a bit stuck on how to complete this task though. I tried using a web browser and that allows changes and with a very minor bit of work the document can be modified and saved. I also tried using process.start and that just starts up the word application as does SetParent.
Is it possible to just take snapshots of the document and view those? Or to open the document as a readonly document?
Anyone here kind enough to give me a code review on the following pattern that I have used for database access? I have provided one of the simpler datalayers to show the basic idea.In particular I am starting to question if using shared methods was a good idea and what problems may arise from that? Will this implementation fail in a threaded environment like ASP.Net?

I downloaded this code from the web that Wierddemon gave me in my previous thread. This solution contains 2 projects (CurrencyControlTest and CurrencyTextBox) There are some things that I don't understand:
1. What's the type of form1.vb and program.vb in the CurrencyControlTest Project? Are they classes, or windows Forms or module?
2. This is the code in Program.vb
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic
[CODE]...
What's the effect of <STAThread> code?
3. What is exactly the "Namespace" doing in this code? because when I removed the namespace, An error indicating that Form1 is not declared appeared. What is namespace? what does it do? Can anyone give sample code to emphasize the function and how and when to use the keyword "Namespace"?
4. This is code for Form1 in CurrencyControlTest Project
Imports Microsoft.VisualBasic
Imports System
Imports System.Collections.Generic

What's with the "public partial class Form1"? what does "partial" do? When i right-clicked on the InitializeComponent(), A portion of code appeared suddenly with the header #Region. What is this? and when re-open the Form1 in "View Code" mode, they're gone.

When I started at my current employer I inherited a project from a previous developer and in that project was a data access utility class that tries to simplify a lot of the code involved in making calls and retrieving data back from the database. Over time it has been modified to add more overloaded forms of functions, and now I am looking at possible suggestions from the StackOverflow community.What do you think should be added? Removed?odified?Note:It would be nice if this class could remain compatible to VB.NET in the .NET 2.0 framework. We are also developing in 3.5, but I would like to have something that is generally going to work across most frameworks (so no LINQ, etc.) Also, please refrain from unnecessary answers that consist of nothing but "Use nHibernate" or other tools.

Basically I have a test tomorrow in CPS 110, my programming class that I am completely lost in. I plan on becoming a network admin and not a programmer but I had to take the class. Anyways, here is the email of the review my professor sent me. Following that I am going to say what I need help with.
CPS 110 Spring 2009 (Singh) Review topics for Test 2(You are expected to remember the previous stuff: datatypes,if / if-else statements and booleans).I. Select case statements: write code/walk through
II. Strings and built-in methods. You CAN use the handout about strings and characters from class on the test.

With a function being passed a full path to a file, such as C:someFolderanotherFoldersomeXML.xml, determine whether the folder exists. Is there a smarter/better/more elegant way of doing this? Here is my implementation:
[code].....
There are a lot of different generic collections available, so the wisdom in creating a new one may be questionable right from the start.However, I often find myself wanting the same features from my custom generic lists, but cannot quite find all of those features in an existing object; namely, I would like to have a generic collection which works like a List or Dictionary (much like the System.Collections. ObjectModel. Keyed Collection(Of TKey, TValue)), but also works like a BindingSource does when it is bound to an ADO object (that is, it supports full sorting and filtering as well as currency).A feature I almost never need however, is transactional adds (the BindingSource's ability to 'cancel add-new').Again, with so many existing collections out there, I should take a moment to go over the reasons why none of them quite meet my needs.There is the System. ComponentModel. BindingList(Of T) which would provide some of the functionality of a BindingSource, but has strict requirements about the type {T} implementing IComparable in order to support sorting, and does not provide filtering (it is not an IBindingListView).It also only maintains a base item list by index, so does not provide keyed access.We could use simple databinding with a custom list inheriting from System.Collections. ObjectModel. Keyed Collection(Of TKey, TValue) bound to a BindingSource, but again TValue would have to implement IComparable to support sorting and we would still not have filter support.So to get all the features I was after, I decided that the best thing would be to create a new generic collection object which implemented IList, IDictionary, IBindingList, and IBindingListView (along with a few others) and would be capable of serving as a simple list, or as a binding source while providing full sorting and filtering over any newable object type.
To that end, I've created the KeyedObjectModel which contains the KeyedBindingList(Of TKey, T) generic collection/binding source. This collection can be used as a typical list, or as a binding source (you do not need an additional BindingSource component between the collection and UI controls, although you could certainly have one).Various constructors are provided in order to initialize an instance of the collection as either an enhanced list-dictionary, or as a complete BindingSource.Any object that has a public constructor which takes no arguments can be used at type {T}, providing that the object has a property of type {TKey} which will contain unique values for each entity in a given collection.If the object implements System.ComponentModel.NotifyPropertyChanged then the collection will also bubble up property changes on the current item to the collection's CurrentItemChanged event.An implementation of IComparable on type {T} is irrelevant because sorting and filtering are performed on the property values of {T} based on the type of the specified property.The current design of KeyedBindingList(Of TKey, T) is in an 'alpha' stage.The class is mostly complete from a feature implementation standpoint, however, the code has not yet been optimized and the base collections of values, keys, and view are being maintianed in generic lists of their own, rather than raw arrays.However, even without performance tuning, the collection appears to be performing quite well, up to a few thousand entries, given the amount of flexibility and funcitonality it provides.At this stage, I would really love to get some peers to try using the compiled DLL and beat up the collection a bit.Once the code has been proven and optimized, I will publish it as an example.It is a fairly complex class though (currently made up of eleven or so partial classes) so I don't really want to post the code until it has been optimized.

so i have this code which is trying to allow the user click the label (of which there are 26) and then decide whether the letter in the label matches the letter that has been generated in the radio button. I KNOW there is a more simplified to do this and much less code to write but i cant work it out. this is an image of what im trying to achieve but instead of buttons change those to radio buttons x 3.
