I'm trying to create an application for a class buy I'm having a hard time. I have started it but I don't really know how to implement the message box or calculations
Here is the question Here is the code I have so far
Private Sub btnCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalc.Click
' declare
Dim diameter As Decimal
diameter = CDec(txtDiameter.Text)
I have a desktop application designed (VB.NET 2008 and SQL2005) which consists of user login and some access level for the users.The user class which i have classified are :
1. Administrator
2. Operator
3. Report User
This user has got a few access in my application. I have got stuck how to create a user class and give access level for this class and map those class to the users.
so my question is relatively simple, can I create VB6 application that references a class in a dll, and then substitute that dll for another at runtime?Now my intial guess is... no chance in VB6.
So my thoughts turned to a VB.net interop dll. Could I do it in here, and then call the interop dll from the VB? but I'd be happy if someone knew differently.The only thing that I think would actually work would be DI in .Net, but I'm limited to .net 2, or 3.5 at a big push, so I dont know if that is possible.
I have a dll that a specific site uses, but we dont want to ship that out to everyone. Instead, we want to build a clone dll which just has the interfaces setup so that the VB6 build will complete.When it gets to the site that needs it, they want to replace the dummy dll, and drop in their version instead.
Note: We do use RegFreeCOM when its gets installed, so I do have the manifest files that I could play around with if needed.
creating a class.cs in a win form app? Here is some code I will use many times in my application...

I 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've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

I want to read a number of items from a file and then associate each of those items with a new button at run-time, so that when the user clicks one of the buttons I can display some information about that item.Can I use a LIST to manage these buttons and items? Can I create a new class and have each list item of that class, such as 'btnID', 'btnText', etc... ?

I'm in the process of trying to create a class that will allow me to create windows shortcut; Im using the following PDF file that gives me the shortcut file structure.
Ive been able to successfully load a shortcut file and parse its Lnk File Structure but now Im on the Shell Item ID List structure but I cannot find the Structure of the ITEMIDLIST anywhere
Furthermore I know I could use the Windows script object, but this is a dependency Im trying to avoid if I can, hence writing my own Shortcut class.

View 4 RepliesI understand this is possible but I am not sure where to start. I want to either buy or create an application that captures a resource from another application so that I can fire off another application. In other words, I want to start an application (which I did not write) that is database driven so the form has a number of text boxes. When someone keys something into that field I want to be able to validate the value, outside of the original application. For instance, if the program asks for a zipcode and it doesn't validate the zipcode, I'd like to trap for that and write something that would validate it. At this point I don't think I'd have to send anything back to the textbox/resource.

View 1 RepliesI have recently been working with creating a GridView from codebehind to make it more flexible so that I can eventually have it created based on user specifications.Now I'm exploring classes, and I thought it would be cool to create a GridView class so that whenever I need to make a GridView I can just pass the class my specifications instead of having the same code re-written on each page's codebehind.Here's how I'm currently making my GridView with codebehind. Any idea how I can change this to create the GridView with a class?
.aspx page:
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AutoGenerateColumns="False"
EmptyDataText="There are no data records to display." AllowPaging="True"
CssClass="GridViewStyle" GridLines="None" Width="100%">

Dim oIncident as New Incident
But after I type "New", normally I would see my class file he intellisense but I do not. So it does not seem to be able to find Incident.vb. I have not seen this behavior before. Trust me, my class is correct. I have created many class files like this.[code]...

However when I try to use the class in VB (after adding the reference) withDim test As ComDotNet.HelloDotNetSet test = New ComDotNet.HelloDotNet("Hello")I get an error.
If I remove the argument from Sub New() everything works fine.
