i have 2 classes. Temp1 and Temp2
Instead of doing
dim clsname as new Temp1
Temp1.GetData("dfs","dfd","fff")
How can i do it where I specify the class name
int=1
dim clsname as string = "Temp" & int
Then somehow use clsname - i tried Activator.CreateInstance but need some help
Public Class Temp1
Private _Account As String
Public Sub New()

I've created a dialog which I'd like to popup from any function or sub in any class or form that I have in a project. It would nice to have it work exactly like a messagebox except it's got a progressbar and a cancel button on it. It's job is to display the progress of other functions so it should just stay open until I close it or the user selects cancel.Now I've found many of the basic examples on the net and have got the dialog working exactly as they have shown it. The trouble is that the examples are using a counter or thread.sleep which simply adds +1 in the DoWork sub. In other words, it validates that a worker thread can update a progressbar but it's a closed loop that only exists in the dialog's class.The examples don't show how to call an unkown function in another class dynamically, they're simply a hard coded 1+1 in DoWork. To me it's not a real world example because it doesn't show how to plug into the dialog or get a communication stream from other classes and functions that are running and wanting to increment the progressbar.[code]

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

I need to dynamically call web service! For this I made simple web service Service1.asmx
Then I created the proxy class for the Service1 Web Service, I use the WSDL.exe utility and following command at the command prompt: wsdl /language:VB /out:myclass.vb http://localhost:3245/Service1.asmx?WSDL
This command create class myclass.vb. That class I include in my Windows Application project, but when I do this I get lot of errors.
This is the how created class look like:

View 3 RepliesI'm having one basic aspx script that needs to load some "plugins". Every plugin has its own settings and it should perform different logics. What i'd do in php is create a class for each plugin, load that class, pass the settings file to it and call some method on that class that would give me some output. But is it even possible in vb.net? I'd need to have multiple files with multiple classes, load those files, depending on the plugin name and call some method on them to parse that plugin's settings.

Am a geriatric coming back to programming after a decade's rest. Keeping it very simple. An empty form. As the form loads, create a Black button (OK) and also create a class which itself creates a single Cyan button. Am using VB 2010 Express. When I run, it creates the Black Button but not the Cyan (i.e. the one that is generated by the class).

We use a common web.config file to store all of our database connection strings.
I would like to have a way to read in all of them, somehow create a property or type so that they become dynamically available.
So when I want to create a new sql connection my my class can show the connections strings available.
Dim myconn as new MySqlOps.Connection(MySqlOps.ConnectionString)
so when the user types MySqlOps.ConnectionString. it will give a list of the connection strings read in from the config file.
Not sure how to approach making the connectionstrings available like above.

I created an interface where user will define the parameters and the submit button should able to do following:
1) Generate C# class.
2) Compile.
3) Execute Method.
4) Attach generated class file to the existing DLL.
I can able to finish 3 of the above items successfully but I can't able to Attach new generated class files to existing DLL file.
So Im iterating through the properties of a class. For each property Im iterating through a datatable until I find a column name with the same name as the property.
No worries so far, here's the isse: Once I've found a match I want to set the class's property to the value in the datatable but I'm having difficulty referencing the property as it has to be done through a variable.
Code:
Dim per As New Person
Dim t As Type = per.GetType
For Each p As PropertyInfo In t.GetProperties
