Passing A Type As An Argument?

Aug 12, 2010

I'm using VB.NET 2003 with .NET Framework v1.1. I know it's getting a bit old now but I'm stuck with an existing program and don't have the time/knowhow to convert it to anything newer.

My question would probably be solved very easily with Generics in .NET 2.0 but as I can't use that right now, I'd like to know if the following is possible:

I have a load of manager classes which inherit from DictionaryBase and hold collections of my custom classes. For example, I have a Employee class, a Batch class, a Supplier class, etc... and each of these has a Manager classwhich holds a collection of them - eg: my PlantTrayMgr class holds collections of PlantTrays, etc..

I have one particular form where I have to populate loads of comboboxes with the contents of various Manager objects. What I currently do in my form load event to populate comboboxes is this:

Code:
Option Strict On
Option Explicit On
Private _plantTrayMgr As PlantTrayMgr

Function Returning An Object With Type Specified In The Argument

Mar 22, 2011

How can I create a function that returns an object of a certain type, which the user of the function specify in the argument (using vb.net 2010) ?

[Code]...

The code above doesn't work, but maybe it can explain what I want to achieve. Using this feature, I want to hydrate my data transfer objects from datatable. Client will just call this function, specifying which DTO the client wants, and this function will just create that DTO and populating the properties with reflection GetType.GetProperties().

'To get size from Class Calculate(Class 2)
Public Sub GetSize(ByVal txtForm1 As TextBox)

[code]....

Event Argument For The Form Click Event Has The Type "TimedEventArgument"?

Dec 23, 2009

As you noticed, in the code bellow, the event argument for the form click event has the type "TimedEventArgument".When the event is raised, e.Time holds the time where the form was clicked.Add the missing code in the class Form1 to make this work.You will not change anything to the methods "Form1_Click" or "Form1.Load".You will not use Option Strict On. HOWEVER, you will not do any narrowing or late binding that wouldn't have been allowed if Option Strict was on.You cannot create any new Class, Structure or Module.You cannot cast the EventArgs to TimedEventArg in any way

Argument Not Specified For Parameters

A fast-food vendor sells pizza slices ($1.75), fries ($2.00), and soft drinks ($1.25).Write a program to compute a customer�s bill.The program should request the quantity of each item ordered in a Sub procedure, calculate the total cost with a Function procedure, and use a Sub procedure to display an itemized bill. A sample output is shown in Fig. 5.26.Coded it out but when I try to break it down to separate functions I keep getting:

Error1Argument not specified for parameter 'CalculateFries' of 'Public Function CalculateTotal(CalculatePizza As Double, CalculateFries As Double, CalculateSoft As Double) As Double'.

Argument Passing In C# And .NET?

Jan 14, 2012

In VB.NET, can we pass an original object as an argument without instantiating it? For example, I have two forms in my project formA and formB. Now I have this code.

[Code]...

Apart from this, in VB.NET in any class like formA, if I type formA, I can see all the objects and controls present there but not in C#. Again, I have to make a new instance to see all the controls. This becomes a problem if I want to manipulate two running and working instances with each other. So what basic thing am I missing here?(I am an amateur programmer migrating from VB.NET to C#. Things are going nice and clean expect for the ones I've recently figured out.)

Using A .net Dll In C#. Getting 'invalid Argument'?

Apr 19, 2011

Got a strange one and I know it is something silly but I can't see it for anything I have a DLL created in VB.net (No I can't change it! :-)) and am calling it from C#. The problems come at the point the object is created in C# and I get the message that it has "some invalid arguments".

The constructor code in the DLL is as follows:

Sub New(ByRef Connection As IConnection)
The code in C# is:
IConnection conn = new Connection();
CustomObject test = new CustomObject(conn)

It is happy with the first line but it gives the error message ("some invalid arguments") on the second line. I have also created a secondary project in VB.net and called the DLL and it works fine there.

.net - Exception With String Argument?

Jul 28, 2011

I have :

Dim con As New OleDbConnection(My.Resources.ConnectionString)
// Give exception = Format of the initialization string does not conform to specification starting at index 62.

When I substitute the actual value of the Resource, it give no exception :

Dim con As New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:
awData.xlsx;Extended Properties=""Excel 12.0 XML;""")

The value of ConnectionString in Resources :

<data name="ConnectionString" xml:space="preserve">
<value>Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:
awData.xlsx;Extended Properties=""Excel 12.0 XML;""</value>
</data>

I don't understand why is this happening ?

I think this should have been replaced even before the compilation process..

Then why is it giving exception ?

Call Form With Argument?

Jan 11, 2010

I have a form that loads in my project and does some task on its own, then closes itself. I'm implementing a new functionality into the program where I need to call this form with an argument (to later be used as a conditional clause). If I call the form from a certain button, I want to launch the new form with an argument ("automatedTicket") and I will then use this argument as a conditional test in the code of the form.where, in the ACCEPTING form do I put the argument declaration?

basically i need to do something like:

ServiceTicket.Show(False) 'false for being a manual ticket (click of button)
ServiceTicket.Show(True) 'true for being automated (no user intervention)

then in the ServiceTicket form, where do I put that I'm expecting one argument? and where do I declare that argument name (automatedTicket)?
