My problem is that I do not want to inherit this class, but I have other classes that need to access the ds DataSet property. If at all possible I would like to not use inheritance and not load my datatable more than once in the program.

View 8 Replies.net - Where To Keep A Structure: Class, Module Or None
Apr 18, 2011This is purely a coding practice question concerning VB.NET structures. Where do you keep one?As an example, I've created a structure for the simple purpose of keeping information organized, I'd like this structure to be stand-alone, not belonging to any class so I wouldn't have to access it through SomeClass.MyStructure but rather simply MyStructure. So, do I keep it in a separate class and import it into my namespace? Do I keep it in a module (Static class, essentially)? Do I just make a separate VB.NET code file and place is there (I would like it to live in a separate file). Just to clarify, I need this structure to be accesses by the whole application, not just a single class.

Mar 6, 2009I'm working on a program that I have 90% finish.Its basically validates certain information such as credit card, telephone numbers, name etc...
Im trying to create a separate class 'IsValid'to figure out if the creditcard number is valid (is equal to 12 characters only).
This will be initiated with a "Validate button".I know how to do this in the mainform just using an If statement.
But I'm trying to figure out how to valid date this and return it to the form and possibly change cardnumber.forecolor = color.red
Class Can Do All The Jobs That A Module Can Do?
Sep 6, 2010Recently i studied about Module and i think it is a Shared Class and all its members are Shared by default and we can not change that.

Oct 31, 2010Im going through the 2008 Express tutorials on methods and classes. Since the advantage of subs, functions, methods, etc is their reusability, how does one save them and later import them into an application?
Also when one writes a class, how is it tested without being part of a form? Besides testing a class, why would one wants to write a class without a form, if it is to be published for a user?

View 14 RepliesAccessing Certain Functions In Class
May 9, 2010I am currently trying to write classes so that I can access certain functions from any form within my VB project.
My class is defined thus:-
Public Class testclass
Public Function showmes()
MsgBox("Hello everyone"")
Return 0
End Function
End Class
I have added the class into my form using this at the top in the form:
Imports WindowsApplication1.testclass
Obviously, WindowsApplication1 being the name of my project, testclass being within a VB file, saved with my project.
I have attempted to call the function from the form using this:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
showmes()
End Sub
However I am getting the error "Reference to a non-shared member requires an object reference." I don't understand why there is a problem, since I have used imports to reference the class.
Calling A Webpage From Within A Class Module?
Jun 1, 2009I have been given an ASP.Net assignment at work because I had taken a few courses a couple of years ago. Currently, there are no ASP.Net programmers for me to ask here and I have searched several places (including Pro ASP Net book) to find a solution but have come up empty handed.
I have a class named spErrors which takes the values passed to it. Values passed include the offending page,function/sub, and other values and stores them in property values, then calls Response.Redirect("Errors.aspx") from the page's code behind page. In Errors.aspx, the values of the error/exception trapped in the Catch statement are displayed. This works fine from a web form. My question is, how do I call a web page from a class module?
Each class module has the ErrorHandler() procedure that passes these values to the class object. In the class, there is a Write Only property named Redirect and a method called Execute() which is used to display the error page if the error occurs in another class module. Since Response.Redirect() does not work in a class module, what namespace is needed in order for this to work?
Here is the code I'm using.
In the Catch block.
Catch ex As Exception
Err.Description = ex.Message
ErrorHandler(Err, "function name")

Class Module Which Is Shared Between The 2 Projects?
Mar 29, 2010I have no idea what is going on here but it is strange to say the least.I created a new solution in VS2008Pro under windows 7 This solution has 2 projects one for the pc and one for a CE based device.There is one class module which is shared between the 2 projects.In VS2005 under xp this same basic project worked fine but here I am seeing error messages that appear out of no where.
Example the CE portion flags 3 lines initially 1 related to a file i.o function and 2 others related to socket methods. All three of these were supported in VS2005 using framework 2.0 which is the same framework I am using here. This is just the tip of the ice berg however.If I attempt to run the code it runs fine for the pc client and of course not for the CE device. If I make any kind of change, add a line, comment a line or just add a comment I get lots more errors with odd messages that are not even valid.
In one case after I saved it jumped from 3 errors to 30, in another case to 50 and yet another to 144 errors yet the only errors that were present were the original 3 that were flagged.The ide threw errors like Try Catch must end with matching End Try.Get no longer supported ' apparently referring to the binary file get but here it is used as the get portion of the property.Get must end with matching end get.It also started complaining about functions and data types.For example saying "an is not declared" pointing to the word Boolean Or telling me my functions are not declared point to only 1/2 of the function name.
I do not see any errors in the code and it reports no errors in VS2005 under XP.As a test I tryed adding a new property to the project after it was telling me there were 144 errors. I allowed the ide to do most of the work and when I hit enter the errors went back to 3. Then I saved the project and the errors went to 105 pointing first at the new property just created.

Custom Class In DotNetNuke Module?
Mar 21, 2011I know this can be done as there are other modules out there that have this, but I'm just not getting it to work.
I have created a custom module for a DotNetNuke site. I want to be able to create a class object within the module to hold the information about that object. I can create the object and everything complies. But when I go to use the object in the code-behind it states that the object is not defined. I'm not really sure where to go from here.
This is the beginning of the View.ascx.vb :
Namespace Modules.VacationForms
Public MustInherit Class View
Inherits PortalModuleBase
[Code].....
I'm really not sure why this is not working. I did download another module code to compare and as far as I can tell everything is the same.

View 3 RepliesSet A Module To Behave Like A Static Class?
Feb 9, 2010This questions is for VBers, it's irrelevant in C#.
In VB, when you create a module, all it's fucntions and members are available in the scope without need to type the module name, just like all the VB functions (Rnd, Mid, IIf etc.).
I want to create a module but I should have to explicitly write it's name to access it's members, i.e. it shouldn't be loaded to the scope like a namespace.
Update
For example, I have a Module of extension methods, I don't want all it's members to show up on the scope and in the intellisense.
I want it to be available only by instance.ExtensionMethod().
