Create A Shared Project Wide Variable
Aug 3, 2010I've been looking at using PROPERTIES [URL] but frankly I don't understand it that well. Before I invest the time to read, understand, and truly comprehend this, I want to make sure it's the best way. My intended goal is to create my database connection string in a function/sub somewhere, then assign it to this project wide string variable, then I can use it in any form, project wide without having to recreate it.

Way Of Hiding Forms And Classes From Main Project
Aug 31, 2009the client has asked for all forms and classes to be hidden from the main project, so when he sells it, they will only be able to see part of the project and not all the classes and forms.My Solution: I have created another project called project2, and added all the forms and classes from main project, fixed all errors and compiled it.I deleted all the forms from the main project and added a reference so that it gets all the forms from the other project by referencing the dll file, but it does not seem to work and get a lot of errors.is there an easier way of hiding the forms and classes from the main project or do I need to do more then just add the reference.

IDE :: Windows Forms Classes Appear As Class Modules Not Form Modules In Project Explorer
Jan 7, 2011Yesterday I opened Visual Studio (2008 v 9.0.30729.1) and all the winform classes in my project display with class module icons with the little 'VB', instead of form module icons with the little form icon!
When I double click on a form module, the form designer doesn't open, just the code module.
When I run the project, it runs fine. There are no errors. The project builds fine.
I did Project --> show all files, and I can see the designer and resx files below the form module which doesn't look or act like a form module.
I can't open my forms to design them!

Asp.net - How Are Classes Shared Between Projects In The Same Solution
Jan 29, 2011Currently, I have a solution that contains two projects (ASP.net websites, FWIW). If I create a class in Project1, how do I expose it to Project2? Is it automatically available to Project2 because they are in the same solution? Or do I need to do something special to make the connection?

View 6 RepliesIDE :: Declare A UserControl As MustInherit, And Then Use Its Child Classes In The Designer?
Aug 13, 2009When attempting to create a UserControl type that must be inherited, when I try to edit one of its child classes in the Form Designer, I am not allowed to edit the child UserControl with the message:
To prevent possible data loss before loading the designer, the following errors must be resolved:
1 Error
The designer must create an instance of type "XX_ExpandContentsPanel2.IOCardMaster", but it cannot because the type is declared as abstract.
This error goes away if I remove the "MustInherit" restriction.Is there some way around this or do I just have to accept the (bonkers-mad) restriction, and not declare my class as as MustInherit, even though it's not a useful control in its own right?
.net - Access Shared Members In Partial Classes
Feb 16, 2011I'm writing a WCF-Service and I split up my service class to multiple partial class files, so every ServiceContract-Implementation gets its own file. I have one file however that should contain e.g. members that are used by every partial class file such as a logger. The service is hosted with IIS 7 if this matters in any way.
[Code]....
The code compiles fine, but at runtime I get an BC30451: The name m_Log is not declared Error (Don't know the exact words for it. I get a german message ;) ). I don't think it has something to do with the type of m_Log or a depending assembly because I get the same error if i try this with a String. What am I doing wrong? How can I make this work? Edit: I was trying the same thing in a simple console application without any problems. :(

View 3 RepliesC# - ASP.NET's App_Code Folder And Shared/Static Classes?
May 15, 2011If I have a 'Shared' object defined in the App_Code folder; is that object shared amongst all users/visitors of my website? Or is it shared on a per-user basis?I don't know if that makes sense or not; but I've got a puzzle/solver I'd written earlier that I'm trying to incorporate into a simple ASP.Net site. It's probably poorly written, but I'd used a Shared boolean to determine if a solution had been found. The code works, now as an ASP.NET site, but if two visitors to my site were both validating their puzzle at the same time, would they both be accessing the same boolean?

Use Modules Instead Of Classes With Shared Member Functions?
May 19, 2009Is it considered an acceptable practice to use Modules instead of Classes with Shared member functions in VB.Net?I tend to avoid Modules, because they feel like left over remains from VB6 and don't really seem to fit in anymore. On the other hand, there doesn't seem to be much difference between using a Module and a Class with only Shared members.

View 3 RepliesVS 2005 Modules Vs Private Classes With Shared Members
Mar 28, 2011I've read that modules are basically shared classes. For a module though, you can call a method directly without prefixing the module name. So I can do this: methodTest("abc", mod1Enum.enum2)But for a class with shared members I have to fully qualify the method call, and in this case fully qualify the enum:[code]In our conversion from VB6 to .NET the need to fully qualify all calls like this might be an argument for us to bring our VB6 modules over as modules instead of converting them to classes.
View 7 RepliesCreate A "shared" Variable That Is Shared With All Instances Of A Class?
Jan 14, 2011I seem to be drawing a blank. I'd like to create a "shared" variable that is shared with all instances of a class but not classes that inherit from it. For example.Class A: Shared list As New List(Of String): list.Add("A")
Class B Inherits A: list.Add("B")Class C Inherits B: list.Add("C")The end result I'd like is that any instance of A has just A in the list. Any instance of B has A and B in the list. Any instance of C has A, B, and C in the list. I can accomplish it by creating Instance variables, but I have to construct the list for each instance of a class. I'd like to construct it once for a specific point in the Hierarchy and then share it accross other instances of that class.
