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.

I create several controls dynamically with the function createControl which returns a control
....
ElseIf objName = "COMBO" Then
Dim cbo As New ComboBox
[Code].....
I know that my combobox has 3 items (in that case that the value was 2) I found that I cannot call selectedIndex before create the combobox, but I am kind of confuse here. I tried also to add it to the panel and to the tablelayoutpanel and then set the selectedIndex but I get the same error.

i encountered a problem but this happened on the client side. In my PC, i don't encounter this error.
The error is: System.argument datagridviewcomboboxcell value is invalid
Is there anyone who encountered this problem? Could the client's PC needs updating on a certain dot net fix?

And I use it like this if I would want the selected value placed in a textbox and it works fine
[code...]
However if I want the value to be passed in a string like so:

The string ends up having an empty string value. How do I assign the value I queried to that String?

I'm using WMI code and VB 2008 to see NIC status. So far the queries are working, but the methods aren't. For example, I'm trying to set a network card to use DHCP, I get invalid function with this code:
Dim classInstance As New ManagementObject("rootCIMV2", "Win32_NetworkAdapterConfiguration.Index='7'", Nothing)
Dim outParams As ManagementBaseObject = classInstance.InvokeMethod("EnableDHCP", Nothing, Nothing)

where I was encrypting the string and passing it to another web page to decrypt and get the ids to be displayed as a pdf back to the page. I kept getting an invalid "Invalid length for a Base-64 char array". It was then I realised that the string was getting truncated and that the IE Explorer had a size limit for the number of charaters being passes as a querystring.So I think I need to go the route of posting it.But not sure how to go about it.
Private Sub GetReport()
Try
Dim hawbs As String = String.Empty[code]....
The retrieve document then does: the decrpytion gets the data(ids) and pulls the pdfs.

FORTRAN allows one to use a procedure (function or subroutine) as an argument to another procedure. For example:
SUB Procedure1(x)

RETURN
[code]....
Does Visual Basic 2010 allow this functionality, directly or indirectly?

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'.

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.)
