How can I create a dll in .NET that has sub-assemblies? For example, if I have a project "MyUtilities", I'd like to create a sub-assembly "My Utilities. EmailUtilities" with classes specific to emailing. Then, in a new project, when I add a reference to the compiled dll of MyUtilities, I could access the EmailUtilities classes using code like:[code]

I am using visual studio 2010 and tried to create a class library which I then use in an application that will create tasks using the TaskFactory and execute the class functions from the newly created class library. However I get the instance not defined errors in the application.

View 3 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

View 2 RepliesI am using VB .NET 2003. I have created a user defined Class Library and created a reference to it in my application. Is there a way I can compile the application so that the Class Library DLL is embedded into the application? I would really like to be able to distribute the application without having to distribute the DLL as a second a file.
In other words, I made a New Class Library lets say called TEST. I developed a new class within this library called MYCLASS. I built the Library TEST and created TEST.DLL. I then made a new visual basic project called APP1. I added a reference to TEST.DLL. I now can use TEST.MYCLASS within my APP1 project. The application APP1.EXE will run in the test environment, but if I move it to the runtime environment it will give me an error "File or assembly name TEST or one of its dependencies was not found". To correct this error I can place TEST.DLL in the directory where APP1.EXE resides. I would prefer not to have to put TEST.DLL in the directory. Can I easily compile it into APP1?
I want to create a lookup program for library books using VB6 or VB.net.
I have created a Form1.VB with two listboxes :- Listbox1 Listbox2.
Im using an Access Database with a Library Category Table
Field1: Category
Library Title Table
Field1: Category
Field2: Title
Field3: Author
Field4: Publisher
Using the Data Adapter ConfigurationWizard Ive created
OleDBDataAdapter1
OleDBConnection1
And from the Library Category table Ive created Dataset1 attached to Listbox1
OleDBDataAdapter2
And from the Library Title table Ive created Dataset2 attached to Listbox2.
Both Datasets fill using the Preview Data function. I then load Variable CategoryString with Listbox1.text,
and I would like to know how to search Dataset2 and retrieve all titles linked to that category and display Title, Author, Publisher in listbox2.

View 12 RepliesI have two projects; A and B, where B needs to use some classes that are in project A. Hence, I added B to A's solution, and in B I added a reference to project A.
Is that sensible? Or should I rather put those classes in a class library?
I see that if I further want to open form/program B from a menu option in project A, then A needs a reference to B. Which would not be possible if B already had a reference to A. However if I use the class library for the common classes, then it's ok as B doesn't need the A reference.
Does this sound logical? It would be nice to know what are typical reasons for putting projects in the same solution, and if it's advised to use libraries aggressively to refactor common code between two projects, even if it's just a couple of classes.. Yet I've never made my own library, so a bit unsure on when to use it.
I have a DLL library, but I am not familiar with it. How can I get its usage in vb.net?
View 2 RepliesI was looking at tutorial that was detailing how to Build a Class Library Component and Consumer Client Application. One of the steps involved was how to add a reference to a library. Am I right in assuming that the reason for adding a reference is to show Vb where class library is located. I would also like to know if it is possible to add the reference within the code. In the tutorial the reference was added via the top menu (selecting project and add reference).
View 4 RepliesI am running through an issue for which I am unable to find a solution.My goal is to:1- compile a x64 .NET library (vb) which has a simple User Control 2- Use this dll in a .NET WinForm application targeted to x64 CPU ONLY.
I have been able to do the first step, but now I am unable to add the library into the VisualStudio Toolbox. With our previous x86 version we had just to right click to VS toolbox, click on "Choose items...", then brows to the needed x86 assembly. If we do the same selecting a x64 lib (of course I am running vs on a 64 bit OS), we get the following message "[DLL PATH] is not a Microsoft .NET module."
I have decided that I want to learn a bit about sound and how it works so I thought that I would make an application that reads and plays MP3 files. I know that this will be very difficult and that I will be re-inventing the wheel, but it's all for the educational purpose. So my questions are; How does it work, how does Windows Media Player plays the data from the MP3 file? How can I, with the data provided in the MP3 file, know what to play, how it should sound? Which method would I have to approach to play the sound provided in the file? If you think that I have too little knowledge on the subject
