Run A C# Method Using A ClassLibrary Dll?
Jul 25, 2010
I'm having trouble running a method that i wrote in C# via a classlibrary dll. In C# running the method is extremely simple, but I dont know how to write Visual Basic code that will do the same thing. Here's the C# code that i need to translate into Visual Basic:
ClassLibrary2.
Program test =
new ClassLibrary2.Program();
test.CreateProj();
All i need to do is run the CreateProj() method which belongs to ClassLibrary2.Program, and in the above code i do this by making "test" a new ClassLibrary2.Program object, and then i run the CreateProj() method through test. I dont know much about Visual Basic, but i know that i have to write the code in "Public Sub Main()". how to run the CreateProj() method in Visual Basic code.

I want to move the namespace/dll/source to MillerClassLib. What are the steps to move it.Terry 01

The reason I want to do this as I want to reduce the codes as it is too much for the program to read it everything.

I've created a VB.Net ClassLibrary with a UserControl in it. I can load it from an HTML page and call the methods that I created. This works as expected. I've tried several examples for how to raise an event from the VB code to the js caller, and none of them seem to work (I'm using IE7).

I have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

Write an overload for every numeric type or if possible constrain a generic extension method to just numeric types.

When I am loading an Assembly dynamically, then calling a method from it, I appear to be getting the method from Assembly executing before the code in the method that is calling it.It does not appear to be executing in a Serial manner as I would expect. Can anyone shine some light on why this might be happening. Below is some code to illustrate what I am seeing, the code from the some.dll assembly calls a method named PerformLookup. For testing I put a similar MessageBox type output with "PerformLookup Time: " as the text. What I end up seeing is:
First: "PerformLookup Time: 40:842"
Second: "initIndex Time: 45:873"

Why does my the declaration of my string in the code result in the following error? Is there a workaround?
Code:
<script runat="server">
Protected Sub form1_Load(sender As Object, e As System.EventArgs)
Dim x As String = "</script>"
[code]....
Error: Statement cannot appear within a method body. End of method assumed.
Note: The following page did not fix my issue and instead resulted in the string </script> being output in my page. ( VB.NET hates </script> tag in string literal )

Extension methods are useful for types that you don't own and can't/don't want to derive from and extend (e.g. reference types and interfaces). Obviously, interfaces should be kept as short and to-the-point as possible, so extension methods for interfaces are particularly useful (e.g. LINQ).For classes, especially classes that you own, they're still useful - but I'm wondering how you determine what should be an extension method or what should be a method in the class itself.Personally, every time I think about it, I keep going round in circles with the following thoughts:If it's useful enough, it should be in the class.It's not part of the core responsibility of the class, it should be an extension method - but if it's useful enough, surely it should be the responsibility of the class...

Is there a way to choose between different methods and pass one into another method ?
Sub conditionnal_binding(ByVal list_box_reference As ListBox, ByVal list_box_final As ListBox, _
ByVal dico_source As Dictionary(Of String, List(Of String)), _
ByVal my_methode As ??? )
' DO SOMETHING
End Sub
I wrote ??? because I don't know how to call another method inside a method.
I would like to choose between different "sub-methods". Here is how I would like to use my method :
conditionnal_binding(ListBox1, ListBox3, HTML.dico_basic_attribut, best_method)
conditionnal_binding(ListBox1, ListBox3, HTML.dico_basic_attribut, some_method)
conditionnal_binding(ListBox1, ListBox3, HTML.dico_basic_attribut, another_method)

I'm trying to code an application that selects an appropriate delivery method from a list box. The user should be able to enter a part number consisting of numbers and either one or two letters. "MS" representing "Mail-Standard, "MP" for "MailPriority", "FS" for "FedEx-Standard", "FO" for "FedEx "Overnight" and "U" represents "UPS" I want to code it so that it does the above and displays an appropriate message when the part number contains an invalid letter or letters.
