Jun 19, 2009
iam creating Vb.net classes under the different namespaces after that build that source code,i got the Type Library file.but iam using the Assembly Name in VB6.0 iam not able to getting classes under the namespace wise.
eg: Dim A As New Test.A - It was possible
but iam using with one namespace like
Dim A As New Test.Utility.A
This was not working.
Dim obj As DynamicPDF.ReportDocumentLayout - it was comes correctly But,
Dim obj As DynamicPDF..ReportWriter.ReportDocumentLayout - Not comes like this.
Note:
ASP: it works fine.
Server.CreateObject( "DynamicPDF.ReportWriter.ReportDocumentLayout" )

In VB.net we are creating different namespace level classes. For Example,DynamicPDF - Root NameSpaceTest ,Report are two sub folders in side the sub folders some classes.
1) DynamicPDF.Test.ClassA
2) DynamicPDF.Test.Report.ClassB
using the VB.NET i was generated the Tlb file.

When you develop a class library that will be used by others, are there any guidelines on how you decide what namespace to put it under? I often find third party classes just use the company name as the root namespace but I was also wondering if it is frowned upon (or even possible) to add one of your own classes to an existing framework namespace.

I have a large web app in vb.net 4.0. Its default namespace is configured in its project properties. None of the root-level classes in our app are surrounded by namespace declarations. When I add a .asmx file to the root folder of the website, it compiles fine, but it doesn't work for some reason (already asked why in other topics). So to get it to work, I try to surround the class declared in the .asmx by a namespace declaration. As soon as I do this, I go from zero compiler errors to about a zillion. My app can't find ANYTHING in the root namespace. But I haven't changed any other files, only this .asmx file.
WHY is it behaving this way? How do I prevent it from behaving this way without refactoring the entire app? I would love to blank out the default namespace and add them explicitly around every root-level class, but I'm not sure that would fly with our release manager, and I don't even know if it would fix the problem.

I will preface this by saying Im previously an asp developer and am learning oop programming/Vb.Net
Im working on a 3 tier architecture and trying to abstract my code as much as possible since I have a very large intranet to convert. In my business layer I am defining my classes with management methods. Below is an example of one of my classes.
My question: Is there a way for me to genericaly refer to the class type and object type so that I dont have to continualy refer to the class name/type "ServiceRequest" throughout the class. For example something like:

I am developing a small application with VB 2008 and MS SQL 2005. For reporting using RDLC reports. Everything is going well except page wise total.I need page wise total on each page and each(all) page wise total should be displayed on last page. I need the report output like this.
SrNo. Amount
1. 200
2. 200
3. 200
[code]....
Note : No. of rows/page are not fixed.For group Total I have used Sum function of rdlc table with scope table_Group2 & for Grand total I have used Sum function of rdlc in table footer with dataset scope.For page wise total I have used textbox in Report footer (=Sum(ReportItems!amt.Value). How to get page wise totals on last page again.

I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:
[Code]...
How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?

This class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

I use the streamreader to fill a datagridview. I need to sort the datagridview integer-wise and have tried to use the SortCompare event. To compare the row values i use the function
Public Function CompareIntegers(ByVal value1 As String, ByVal value2 As String) As Integer
Dim int1 As Integer = Integer.Parse(value1)
Dim int2 As Integer = Integer.Parse(value2)
[code]....
Which i call from the SortCompare event with
Private Sub DGV_SortCompare(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewSortCompareEventArgs)
e.SortResult = CompareIntegers(e.CellValue1, e.CellValue2)
End Sub
The event is fired but the datagridview is still sorted as strings.

Suppose there is a three location binary data: xxx, I want to create a NOT operation on the second number and keep other 2 numbers or vs.
For example, 010 --> 000, 110-->100, 111-->101, 000--> 010
In decimal , it means 2-->0, 6-->4, 7-->5, 0-->2

I have a need to construct a command Byte to send to another device using bit wise operations.There seem to be plenty of article on how to do this for indiviual bits using an OR'd constant but how do I do this for values that span multiple bits? eg "Bits 4-1" set the repeat count".so how to I inject a repeat count value of say 7 into my command byte?

I have two classes, one nested in the other. [code]Neither "Name" or "ID" are unique between operations and records.I wish to construct a dictionary using LINQ = Dictionary(Of String, Of List(Of Integer), whereby the keys are uniqe examples of Names in my collection and the values are the collective set of distinct IDs that are associated with those names.

How can I structure my classes so that the user interfaces though a single class while the supporting classes are hidden from their view? I think its best understood in an example:
Public Class MyInterface
Public Economic as EconomicClass
Public Sub New()
MyBase.New()
[code].....
So you might ask why am I even separating them? It's strictly for others who will be working with this interface. I need to funnel them though a logical structure:
interface.Economic.MyMethod
interface.Currency.MyMethod
etc
This way everything is already handled for them in the background and they only need to run the method they need. I don't know if I can have it both ways in VB.NET.

I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
