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.

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,

I've createda vb.net class library where I've defined a number of small classes... nothing complicated, just working with strings, sending emails, etc.In another project, I reference the class library and I'm seemingly able to create an instance ofone of tclasses - intellisense shows me all of the plic properties, methods, etc... all looks perfect. No compile errors at all, nothing b gumdropsand lollipops.When I run the app I'm working on that references the class library, it fails at the point where I'm creating an instance of the class and gives me a vague exception, "System.TypeLoadException".
View 2 Repliesmy aim is to create a new instance box at the push of a button, the box has strings name and Id to be filled concatenating the auto generated ID i.e. 0 to 210 plus a string "Box" added by the user. I had problems earlier creating a structure within the class box, frankly I am not sure if the code below will work, as i try to run it in VB I get an error indicating that I am using the variables strBoxPositions() and strBoxNumbers() without assigning a value to it. The thing is the strBoxPositions() should automatically be filled by arrPosition() which will be created at the same time the new object box is created and the strNumbers() will be created with empty strings to be filled at latter stage by the used as and when necessary.
how could I initialise those arrays to get the program to run and perhaps ill be able to see if the code works or not, or just correct this code with a better way of code with comments, also if possible some indication on how could I update the strNumbers array inputing the strings one at a time on a text box field.

We are migrating our applications to VB.Net 2008 from Classic VB and I need to create a base namespace and business layer. My method of approach is going to be to visit our top BA and identify the common areas of our (Fixed Income) company and try to form a decent inheritence model with as much of the code in generics as possible. What's everyone's experience of doing this and also as a second part of the question, we are looking at incorporating Web Focus into the OLAP side, how would this affect the design of the corporate namespace and it's derivatives?

View 5 RepliesI've added a new class1.vb file to my vb.net project containing:
Namespace MyFunc1

In form1.vb I thought I used to be able to call my functions with:
n = MyFunc1.Add(15, 16)
The error says "it's not a member".These also don't work as expected:
n = MyFunc2.Add(15, 16)
n = MyFunc1.MyFunc2.Add(15, 16)
n = Add(15, 16)
I thought for sure, this used to work:

I'm writing custom code in VS2005 Reports (SSRS / Report Builder). The code is working fine, but I have to make absolute references to assembly classes. For instance:For Each m As System.Text.RegularExpressions.Match In ...Is there any way to alias the reference to System.Text.RegularExpressions.Match, so that I can reuse it in a concise manner? I know in PHP, you'd do it like this:
use MyNamespace\MySubNamespace\MyClassVerboseName as MyClass

MyClass->MyMethod();

I'm moving some stuff around in a program. How do I move a class (or enum, etc) to a different namespace? Right now I am getting 102 errors because even though VS can update name changes, I don't see how to get it to update a move to a difference namespace.
EDIT: Okay, to be more precise, I am moving a class up the namespace tree. So, not just a different namespace, but actually getting rid of the last namespace qualifier.
While going thru an msdn article, I found a reference to System.Query.Sequence class. But when I try to use it, I get error "Query is not a member of System"
vb.net
Public Sub Linq65()

Select New With {.Number = n, .OddEven = If(n Mod 2 = 1, "odd", "even")}
For Each n In numbers

The above code is vb.net version of this code from msdn. So what is the correct namespace of this class? Or I'm missing something else?
I am attempting to use the My.Computer.FileSystem namespace in a WPF VB.NET usercontrol library. I get no Intellisense etc for this namespace. I imagine I need to add a reference but no amount of googling has fixed this and VS.
View 1 RepliesI've currently got a class that has a bunch of functions within it that I'd like to group up. I can't seem to find a way to do this, as the functions interact with the objects within the class (so I can't use a structure for example). Namespaces are only allowed outside of Classes as are modules. Let's say I have Class Foo. Inside Class Foo there are six functions, three that are logically grouped together and another three that are as well.
Class Foo
Public Function moneyFoo1()
Public Function moneyFoo2()
Public Function moneyFoo3()

I want this to work without having to manually pass any references or variables from the calling class to the new instance of ChildClass.
I want to create a class that will "search" for something. Basically I load up the "search item" when the class is created and inside the class is logic to do the "search".
