CPS 110 Spring 2009 (Singh) Review Topics For Test 2?
Mar 31, 2009
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.
i was thinking that sometimes it is hard to learn something when you don't even know what you are missing. so basically i was trying to put together a list of topics on Vb. i wanted to cover everything.. but i do not know everything about vb.
I have a dataset that pulls information about topics. However, I need to filter the information so i only get the topics with certain Topic Codes (These topic codes are in the form of an array).
Me.TblTopicsTableAdapter.Fill(Me.MainDataSet.tblTopics)Right, let me try and explain better.
I have an array named COURSE_Topics. This array contains topic codes as string elements.Currently, my table adapter query looks like this:
SELECT [Topic Code], TopicName, NoOfCourses, Duration, StartDate, EndDate, [Level] FROM tblTopics At the end of that query i need to add a WHERE [Topic Code] = - then list of topic codes in the array.
I'm making small application to posting new topics in phpBB forums... But I have a problem. When I click on send button in my application, forum shows me an error: No post mode specified phpBB posting:
Have never used this website for such questions. Need to create a resume/ Have researched, but have had 4 resumes rejected from a design perspective. Cannot be just a normal resume. Background can be created in Photoshop, Logo in Illustrator.Think I have that one okay. More a problem with the background and design in Indesign.
My OS is Vista Home Premium (64-bit) SP2. I've been working with VS 2010 Beta 2, wrote a few apps, and downloaded the Aug 2009 DirectX SDK. I have all of the source code for a game I wrote ten years ago (with VB5 using DirectSound and DirectInput from DX7) and I would like to get it working with the latest VB and DirectX (and use Direct2D also) but the first problem is that I can't even find how to "include" directx into a project. I was hoping to make a small example app to figure out what I need to do to update my code and what capabilities D2D has, but I can't even get out of the gate with DirectX.
Dim startDate as Datetime startDate = Convert.ToDateTime(datepicker1.text).ToString("dd-MMM-yyyy")
In the immediate window if I try Convert.toDate(datepicker1.text).toString("dd-MMM-yyyy")it is showing date as 29-Sep-2009 but the value of startDate is 09/29/2009 I really don't understand why the value is not set in startDate variable as 29-Sep-2009
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]......
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?
Need to use the create method of the AX 2009 ReturnOrderInService web service in a vb.NET aspx page to create an RMA in AX.The code I've written below creates the RMA in AX, but doesn't show the line details in the AX RMA form, even though the records are in SalesTable and SalesLine.Is a record needed in InventTrans or is there a missing InventRefId value somewhere?[code]
I am looking to do a presentation at work to our development team. I was wondering if their is any new tool which would be easy to demonstrate. It is just an after work thing for talking about new technologies.
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
[CODE]...
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.
Im currently working in integrating GR Fingerprint SDK with vb.net application. I am using MSSQL 2008 as my database and vb.net as the front end. I have completed almost 90% of the application and im stuck in integrating this SDK with my application. It has an error such as Unable to connect to database and also grfinger is not initialized cannot be converted to double and stuffs like dat. [Code]
i need to create a function for transforming an xml document using xslt. I am able to copy the document using xsl:copy-of, however it's not copying the root of the source xml document. As shown below, the root of the xml should be <List xsi:noNamespaceSchemaLocation ~>: [Code]. My IDE is Visual Basic .Net 2008. I need to reproduce the xml file with the SName attributes sorted in ascending order.

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.

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:
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.

I'am trying to write a program in order to obtain a screen picture for a post review of the running window that should be periodically executed with the tasks manager.
I want to find a way to speed up this code.if you look at the condition of If calculated Then in the code below, this is what slowing down the code.While the code provided seem fast with Const initBit = 4 try it with something over 12.
I want to be able to use this code (with calculated param as True) with initBit of 20 or more.
Beware that 20 or more might require a gig or more of ram and/or compiled as x64.
C# code (converted with an online tool from VB.NET):
and from VB6 project I reference to Test.dll but an error messege was appear A reference to Test.dll file could not be added (If I create VB NET project and reference to file Test.dll it OK )
Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.
My DataGridView sorts by date. For grins I entered the date 11-02-2010 fully expecting it to be at the bottom of the list, not listed right after the last 11-02-2009 row and before the first 11-03-2009 row.How do I handle this so that come January 1, I won't see all the 01-01-2009 rows listed first followed by the 01-01-2010 rows then the 01-02-2009 rows, etc?
I did a clean install and tried to get the project running again. The code ... AlteredDate = SelectedDay & "/" & SelectedMonth & "/" & SelectedYear would always work defaulting to DD/MM/YYYY before the clean install. The program now runs an error "Conversion from string "13/8/2009" to type Date is not valid.. How do I change the default back to DD MM YYYY or format it to that?
Dim mDate As Date For mDate = dtpFrom.Text To dtpTo.Text
Next i have tried that code to get the from "1/1/2009" to "3/1/2008" using datetime picker but this error is found 'For' loop control variable cannot be of type 'Date'.
I am playing with the virtual machine version of the Google Chrome OS. I need a web app that I KNOW is made in visual basic to test to see if it will work with it or not. This will help determine if it's possible to make web apps for this Google OS in VB.
