VB2010 Class Library: Create A Static Library Instead Of DLL?
Jun 21, 2011I have a Visual Basic Class Library project. It generates a DLL. Is there a method to generate a static .LIB to which I can do a static link?Alternatively, can I do a static link against a DLL?
View 6 RepliesDB/Reporting :: Transfer Data Between MSSQL And Access With Vbscript
Jun 8, 2009I have a problem with transfering data from MSSQL Server 2005 to Access.
I need to make a VBScript that can take out all data from one table in mssql and update one table in Access. The tables exist in both databases and looks the same, but there can be more data in the table from MSSQL Server so i need to update the table in Access with this data.
E.g. I have a table called: SMP_Alert in both database's. So i want to do something like this (dunno if that is possiable):
Set objConMSSQL = CreateObject("ADODB.Connection")
conMSSQL = "Provider=SQLNCLI;Server=127.0.0.1SMP;Database=SMP;Uid=SA; Pwd=smp;"
objConMSSQL.Open(conMSSQL)
[Code].....
Or do i need to create a recordset of the table (SMP_Alert) from MSSQL, and loop through it to transfer the data into the table in the Access database?
Adding A Windows Service Class To A Class Library
Feb 14, 2012I have a class library in VB.NET that does a NET-envelope for an USB device driver.There is only one function of that driver that I could not envelope in a traditional class, but I had to put it in a Windows Service as described here:Sharing a class property (field) between applications.The Windows Service works fine, but I have now two projects for my NET-envelope: the one with the class library, the second with the windows service and I do not like the idea to maintain two distinct projects for the same driver.Is it a good practice (or even if possible) to add a windows service class to a normal class library (without creating its own project as described in the vb tutorial)?I know, in any case I should create a separate setup only for the windows service, but in this way I could have together all the classes that envelope my usb device driver in only one project.

DB/Reporting :: How To Setup A 'Library' Function
Dec 23, 2008I'm working on a Free, Open Source Multimedia player. I'm hoping if I do it right, I can have it beat out WMP and iTunes. As this is the case, I'm trying to program the whole thing without connecting to either WMP or iTunes through COM or ActiveX, and not use any of the .dlls.One of my current problems is that I can't seem to figure out how to setup a "Library" function. What I'm thinking right now is I want to setup a database, and then connect to it. I was able to create a Local Database, and setup my Table and Fields, but I don't know how to connect to the database; I figured out how to create a new instance of the table, but those get deleted as soon as the program is closed.If anyone has a suggestion on how to do this, or a tutorial they can point me to, that would be fantastic. My only stipulation I have is I'd like to be able to use SQL searches on the database, to make searching for song faster.

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".

DB/Reporting :: Charity Library Management System - VS2010
Aug 15, 2011I have read syedwaqasali95's thread but found it rater confusing so thought I would post my query separately I am trying to build a library system for a local blind person's charity using Visual Basic. Their current system of recording is an Excell Spreadsheet that was created for them by someone else. What they have asked for is something more User Friendly.I thought about using Access first, but I wanted to hide the Data where it couldn't be modified by accident, and I wanted to make it as user friendly as possible so I opted for a VB WindowsFormApplication that will have a simple user interface albeit having to get more complicated under the hood.The library has two types of items that they lend, Audio Books, and Music CD's. Also there will need to be a record of the members creating three tables for my database.I should state that the library has a laidback lending approach whereby it is less worried about how long you borrow a book or CD, rather it just wants to keep a record of the location of said items.
I need help/pointing in the right direction with the following things 1) I want to prevent any ability to directly edit the datagridview data instead I want the user to highlight the entry in the datagridview, and then click an edit button which will open a form containing the record to be edited.
2) I want to be able to call information from the borrowers database, and to be able to apply it to the books data, so that the user can see who has what book at any given time.
e.g. the user highlights a record in datagridview and clicks the "Lend" button, this pops out a form allowing the user to search/choose from the list of members, once a member has been selected the save button (or confirm lend) would add the member info to the book table and close the form
3) I have a large amount of data (1500 records) in the original excel document, I would like to import these (once the database is ready to be compiled) so that they don't have to be re-input.
Made A Class Using New->Class Library
Nov 17, 2009I have made a class using New->Class Library. I have 2 constructors, 1 function (that computes length of circle), one subroutine that computes area of circle, and main subroutine.
Public Class Class1
Class Circle
Dim rad As Double
[CODE]...
My problem is when I try to run the program: No errors of syntax.
What I must do? I need to right click in solution explorer add new item->add->class and copy here this code?
After I write the code I chose from the vb menu: Build->Build Solution_name
Before writing the code I choose File->New->and selected class library then save all to save as a project.
Or class library is only a dll file that runs with a windows forms application. (that is added after i write the code for write library).

View 4 RepliesClass Library Or Not?
Oct 18, 2010I 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.
ConnectionString In Class Library
Apr 27, 2011I'm merging two of my projects that can share a lot of the same classes into one solution with two web applications and a shared class library.

View 2 RepliesClass Library (DLL) And Distributing?
Oct 7, 2011I'm in the midst of developing a class library DLL for a third party application. On my machine, the developers machine, things are going along smoothly. I can compile/build and my DLL is loaded, and thus works as expected.
I've been copying the contents of the Release directory from C:Solutions...Release to C:ProgramDirectory. I realize now that my DLL is loaded into memory from the Release folder, and not the folder I copied it to.The point being of course, I want to distribute this third-party add-in to my users. And sure enough when I try that, presumably the DLL isn't loaded into memory and thus not available to the user, like it is on my machine.
I tried the first obvious thing and registering the DLL on the user's machine, but that failed."The module "..." was loaded but the entry-point DLLRegisterServer was not found." It's apparent I am missing some key step or caveat when it comes to developing this class library.

Class Library Events?
Mar 6, 2012I`ve made a .NET component in C#. After that, i`ve created a class library in VB.NET and added this C# component and a couple of buttons to the library (creating another component now with buttons). So far, so good.The problem is: when i use this final component (vb.net class library), i want to link all MouseClick Events of its own components (buttons and C# component). In other words, when i add this final class library to my VB solution, it has its own MouseClick event. But when i click inside it doesnt raise the click event unless i do not click in the buttons or in the C# component inside it. I want to raise this event in the application wherever i click (inside or outside its own components).
View 14 RepliesConvert A Class Library For Use In GAC?
Sep 18, 2009My objective is to take a .vb class file that is used on multiple local applications/web sites and convert it to a .dll file that would would be deployed to the servers that we use.The code all works, I can build my class library project with Visual Studios 2008 Pro and end up with a DLL.I can then drag and drop the DLL into any application or website and use it successfully What I'm missing is how to compile it correctly so it will do two things;
1. Get it to show up as a .NET component
2. Get it to NOT scream at me when I try to reference it.
I think part of my problem is that I've been looking up assemblies and dll's when maybe I should have been looking at component authoring.No, I don't want to just stick with the drag and drop into local bins. I might as well just copy and paste the original .vb at that point.

Writing A Class Library?
Apr 9, 2012OK, so its many years since I last did anything with VB5 and I now have a requirement to write code in VB2010uld like to put together a proof of concept for a project I am involved in.A lot of our coding exists as VBScript, but I need to add some functionality that VBScript does not offer, and the obvious path is to create a .NET DLL that can be called from VBscript. What I want to be able to demonstrate is the ability to edit a hex character at offset 15 from the beginning in a file not exceeding 2000 bytes. The filename of the target file will be passed from VBScript.
So from a vbscript perspective I would be coding something like:
dim‚myObj, filepath, decval, offset
filepath = "c: emp estfile.bin"

C# - Call .NET 4.0 WPF Class Library From 2.0 Application
Apr 8, 2011I have an application written in .NET 4.0 that i compile into a DLL file. I want to be able to use this DLL file in a Windows Forms .NET 2.0 application. I don't need the application to really interact much, except just passing a couple string values to the 4.0 DLL. The DLL is pretty much a bunch of Windows which i converted to UserControls and i just need to be able to reference them to display the UserControls from the 2.0 application without having to use a different exe and having to package them separately.
What is the best way to do this? Because when i try to add the reference to the DLL to the 2.0 application, it gives me and error saying the DLL is built in a newer version of .NET so i can't do it that way. Is this where a COM object would come in?
