This is hopefully a softball syntax question: I need to call a method with an empty Object array for evaluation and set initial state. In C# I would just do this:
func(new Object[]{});
In VB.NET I am forced to do this:
Dim ctrls() As Control = {}
func(ctrls)
Is there a way to shorthand the call in VB.NET and have everything happen in one line of code?

I want to pass an XmlDocument as a parameter to my webservice method. After I have loaded an XML file from a path, when I try to send the XmlDocument as a parameter by webservice method, I come across this error. What can be the reason? I use StreamWriter and I close it. I don't use XmlWriter.The development environment is VS 2008
Error Message:
Cannot write XML declaration. WriteStartDocument method has already written it.
Edit (from comments):I can't post all the code because it has more than 1000 lines. Also when I load Xmldocument in web, I can't use this method without problem. Maybe Webservice causes a problem?
Dim xml As New XmlDocument
xml.Load("My Documents" & xmlfile & ".xml")
myTransfer.Save_XML(xml, 1)

Question: How to shorten this array creation ? I need to create an array of type ReportingService2005_WebService.Property with one property.

Dim PropertyArray As ReportingService2005_WebService.Property() = New ReportingService2005_WebService.Property(0) {}

View 3 RepliesI have been working on an activeX control which works on serial port communication. Now I have completed the project and created its setup.exe using Visual studio 6 -> Tools -> Package and Deployment Wizard. Then I installed the control in another PC and in a new project included the control using project -> components. But when I click on the control in the toolbox and then include on the form it gives the following error : delete current link ? and on clicking OK, nothing happens. I tried searching a lot on google but didnt find anything. Another problem is that I have created a string array as a global array which can be accessed by all the methods.I am able to include the same activex control in my own pc when I have created the project. Here it works fine, I am able to access all the methods that I coded in the control, but the String array mentioned above can be accessed in other project. I tried writing Public before the array declaration but it give me the compile error : "Constants. fixed length strings, arrays, user defined types and Declare statements not allowed as Public members of object module."

Currently, I have code similar to this:
xxx, _
If(dr.Table.Columns.Contains("EnterpriseID"), dr.Field(Of Integer)("EnterpriseID"), -1), _
xxx
I would like to create a Lamdba expression something like the following (this doesn't work):
Dim xCol As Func(Of DataRow, String, Type, Object, Object) = _
Function(dr, x, t, dflt) _
If(dr.Table.Columns.Contains(x), dr.field(Of t)(x), dflt)
So that I can say something like:
xxx, _
xCol(dr, "EnterpriseID", GetType(System.Integer), -1), _
xxx
