Run-time Error '449': Argument Not Optional

Jun 30, 2009

I am getting this error when debugging a VB application. The method that is being called when I get this does not have any arguments. Definitions in code are as follows with names changed to protect the guilty


The question is, if the method is not defined to accept argments, then why am I having a debug assertion while debugging that says that the arguments are not optional?

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 (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 and called the DLL and it works fine there.

Combobox Invalid Argument SelectedIndex

Apr 19, 2012

I create several controls dynamically with the function createControl which returns a control

ElseIf objName = "COMBO" Then
Dim cbo As New ComboBox


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.

Program Use Only Section That's Needed For Current Execution Instead Of Checking Every Argument Every Time?

Dec 6, 2009

FIRST = arguments checked against each other

SECOND = arguments checked against each other but are irregardless of the FIRST arguments.

If (FIRST and (FIRST or (FIRST and FIRST))) OR (SECOND or (SECOND or SECOND or (SECOND and (SECOND or SECOND)))) then As the program processes this line over a million times during the execution, only FIRST or SECOND section is needed during an execution, never both. How do I make the program use only the section that's needed for the current execution instead of checking every argument every time? Is there a way to turn a string into an argument list for an IF...THEN statement? [code]
