View 1 RepliesI am trying to create a DLL from a class library in Visual Basic.
First I created a new Project in Visual Basic Express 2010 as a class library. Then I added a class which contains a function that I want to access in another program. This is why I want to export the class library as a DLL. In visual studio I am compiling the project which refreshes the saved dll in the bin folder of the project directory. When I open this dll or include it as a reference in another executable visual basic project, it does not find the function. how to generate a dll from a visual basic class library properly?
Here is the code of the class stored in the class library project:
Public Class Test
Public erg As String
Public Shared Function fTest(ByVal in As String, ByRef out As String) As Boolean
[Code]....
I have a class, MyClass, declared as public, with a Shared method test():
[Code]...
If I comment out Response.Write MyClass.test(), everything works fine and I can use the Class - however, trying to access the Shared method, I get the following error: Local variable 'myClass' cannot be referred to before it is declared Any pointers as to what I am doing wrong?
Here is what I have in my file
Option Strict On
Imports MyNameSpace.MyEnum
Public Class AwesomeClass
[Code].....
But since MyEnum isn't defined in the subclass it won't work. I am not very familiar with what these types of things are called, but I think that I am import a type definition of sorts. Since I am Importing, and not defining, it is only available in the first file. Basically, I want to include MyEnum as part of the class but I don't how to do it. I don't want to copy/paste it over, and I don't really want to write Imports ... at the top of all of my subclasses.

View 3 Repliesthis is an interesting problem and to be honest, I'm not sure there's a solution to it. But thought I'd ask the brain-trust here and see what comes up.I'm developing a dll that is loaded and ran within a third-party application. The third-party company provides an API to use that leverages their application's internal objects so that I can automate our processes. It's really pretty slick. They have a class object that represents the internal structure of their supported documents, appropriately titled Database. I would like to serialize the Database class using the ConfigurationConverterBase (to create a TypeConverter for conversion to and from) in conjunction with custom configuration elements and properties to store this information and retrieve when necessary. I've created the converter and all the necessary code for the custom configuration process. And it all works like a charm with one exception... the Database object does not have the Serializeable attribute applied.
Since I don't have control over the API they developed, I cannot simply add it. And since it is sealed, I cannot inherit it. This leaves me with an ugly option of converting the document to a temporary file that is a text-based version of it, then streaming it into memory before creating a binary format that can be saved into the config file. This is an ugly approach, but will get the job done.
Does anyone know how to work around the original issue for a more streamlined approach?
I am very basic with this right now and I'm certain there are ways to do this even more simply than the 2D array, however that is what we are working on right now.

I want to created a nested class that can only be visible to and instantiated from the parent class.But I also want to be able to use an instance of the nested class through a public variable of the parent class.I tried making the nested class private, or making the nested class' constructor private, but it won't compile.Is it possible to do this in .NET?

I can't make difference between public class and private class and friend and protected friend class.

I have two projects, namely:

2. Project2 (Class Library)
in Project2 there are several classes:
* frmLogin.vb
* frmCustomer.vb

View 9 RepliesDoes anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?
How do I disable the background compiler for Visual Basic in Visual Studio 2008?
For my sins, I have to work on a large VB.NET project and it often locks up for 20 seconds at a time whilst doing the very helpful background compilation
I'd rather work blind between compiles and be able to do some work.
I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere. I downloaded the Direct X SDK for August 2009, but I can not add the .dll files to the reference list. Is there anything I can do to add them? I need the references for programming reasons.

I have Visual Studio 2008 Professional and I'm trying to make it so I can click a button to send the application to the System Tray and then click the icon in the System Tray to make the application come back.
Can anyone provide me a method or sample code to do this?
when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.
