VS 2005 - How To Hide URL String In Class Library
Jun 2, 2010
I am going to write a long code in the class library to make the source code shorter for my project. And I willing to store the url strings in the class library, but I do not know how to keep them to be more visible from people who open the dll by using with hex editor. I would like to know in which method that I should use to protected the url strings in the class library and set them more visible so no one would know what url strings that I would store in the class library if people using hex editor?

I am writing my first class-library in VB.NET. My idea is to distribute this library so others may use it in their applications.However, perhaps due to my lack of experience in writing and structuring the library and the classes therein, I noted that the methods/properties are ALL being shown in the IntelliSense of Visual Studio.
The thing is that many of them are only used within the library itself and should NOT be used by the developers (could create a disaster) when they incorporate my library in their application - only a few should be visibile i.e. the ones which are needed by the developer.Thus, my question is: is there a way to hide certain methods/properties of my library from Visual Studio's IntelliSense? Maybe something similar to REM?
EDIT: as mentioned - this is my first library and I now understand that my question could be intepreted in two ways:
1) how to hide something from IntelliSense
2) how to prevent a developer from using and calling certain methods/properties
Of course, the end-result that I want is that the developer is not able to access AT ALL certain methods/properties i.e. No. 2 above.

In my earlier project I was able to change the connection string during the app settings loaded event and it was successfully. When I try to do the same for a code library project, I am not getting the system.configuration.connectionstringsettings to work. Could you please tell if there is a work around for this, or else it is always better to write the sql code instead of depending on the adapters etc.
Additional information: Clients App is WPF with Vb. Database is SQL Server 2008 Code Lib would only be on server, slq connectiona and data retrieving and saving actions are stored in classes in code lib only. Code Lib would be used with WCF, wcf is used to share the classes only and classes have the data. WCF is hosted as a windows service on server used by NET.TCP

You can change the connection string at run-time like this. You make the connection string setting available for writing as a separate property inside the MySettings class:
Partial Friend NotInheritable Class MySettings
Public WriteOnly Property RunTimeConnectionString()
Set(ByVal value)
[code]....
Then, in some place when the application is being initialized (before using any table adapters of typed datasets), write something like:
My.Settings.RunTimeConnectionString = My.Settings.ProductionConnectionString
Where ProductionConnectionString is a simple String setting. It is a User Scope setting so every user can change it (by assigning a value to it, similar to the code above) and save it by calling My.Settings.Save()This code works well for connection strings which were initially created in the main project and stored in it's settings (= app.config file).
The connection string in the app.config actually has a longer name: MyApp.MySettings.MyConnectionString.When you have a connection string stored in the app.config in a class library project, and reference that project in the main project, the app.config files will somehow be merged, so the class library has it's settings.The thing that don't know how to do, is change a setting from the class library at run-time. I could copy the connection string setting from the class library to the main project's app.config. I must keep the same name, which looks something like: MyClassLibrary.My.MySettings.MyConnectionString.Can the same principle I showed above be somehow applied to this second connection string?

I 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.

I have a problem of getting the string from the html class. When I debugged the project and I clicked the button, httprequest was connecting to the site then reading the pattern string from html class to get string, but it filled as a blank text.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Create a request for the URL.
Dim request As WebRequest = WebRequest.Create("[URL]")
' If required by the server, set the credentials.
[Code] .....
I an trying to work regards with the pattern string as "showChannel", which it doesn't filled the string from the html class. I want the pattern string to get the string from the html class such as like this:
<p class="showChannel">Name of program - Saturday 26th December, 22:30</p>
I want to get the time at the end of the pattern string which I want to fill time like this 22:30.

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".

2. Project2 (Class Library)
in Project2 there are several classes:
* frmLogin.vb
* frmCustomer.vb
* clsGlobals.vb
in my case, I want to frmLogin.vb and frmCustomer.vb not called in Project1 and I can only call is clsGlobals.vb

I 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).

I 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'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.
I've literally just dumped all the classes into the class library project and as expected I've got a ton of errors to fix. My main problem at the moment is the connection string. Currently I have this (which is obviously not going to work):
''' <summary>
''' Initialise the data access layer by loading the database connection string from the Web.Config file

I'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.

I`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).

My 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.

I was dangerously close to high-jacking another thread, so I thought I should create my own. We make class libraries so we won't duplicate code, but what about settings? I have a large solution that I've created a project in for common material, which includes an app.config. The problem is that a class library isn't an "app" so my functions can't get to the values. How do I get around this?

OK, 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"

I 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?
