C# - Cannot Pass Arguments In Dispatcher.invoke?
Mar 16, 2012I will need to convert the following VB Form code to WPF C#:
// VB Me.Invoke(New FooDelegate(AddressOf Foo), New Object() {cmd})
Where Foo is just a method taking a string argument cmd.
I tried all the following in WPF C#, but all giving me exception:
//C#
dispatcher.Invoke(new FooDelegate(Foo()), cmd);
dispatcher.Invoke(new FooDelegate(Foo(cmd)), cmd);
dispatcher.Invoke(new FooDelegate(Foo()), new object() {cmd});
What is the correct formatting?

View 1 RepliesForms :: Pass UserControl As An Argument?
Sep 8, 2010I've got several user controls and every time I add them, I post this
Dim uc As New ucTemplates ' 'ucTemplates' is the name of the actual user contrll
gbControls.Controls.Clear()
gbControls.Controls.Add(uc)
So, I'd like to create a sub that does the same thing, passing the usercontrol as an argument
Private Sub AddUC(myControl as UserControl)
gbControls.Controls.Clear()
gbControls.Controls.Add(myControl)
End Sub
But - when I try:
addUC(ucTemplates)
I get an error that ucTemplates is a type and cannot be used as an expression
I can get it working if I add the Dim uc As New before the addUC - but I'd rather have it so I only repeat one line, not 2

View 2 RepliesPass An Array Of Arrays As A Function Argument?
Nov 11, 2010I have several parameters consisting of separate System.Byte() arrays. What I need is the syntax for a function declaration where the parameter is an array of arrays - I do not want to delve into System.Collections, and it's my preference not to CType each array into an Object and then back into a Byte().
Problem I'm having here is that:
Public Function MyFunc(arrayparam() As System.Byte) As System.Byte()
accepts a single-dimensional Array of individual Bytes.
Then Public Function MyFunc(arrayparam() As System.Byte()) As System.Byte()

View 2 RepliesFunction - Pass Object Versus Reference Object In Parent?
Dec 1, 2011I am working on a application that has quite a few functions involved and have been thinking of the following: If I have a function that has a few paramaters, is it more efficient to pass the objects to the function(Example 1) or reference the objects in the parent(Example 2)? Does it matter if the objects are large or not?
Example:
Class mainform

Insert List Object As Argument In String.format
Feb 10, 2012I am trying to pass a list in string.format as the parameters to the SQL statement, but I get the following error: Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

When Passing An Object As An Argument To A Method, String Properties Are Populated But Integers Are Null
Jan 27, 2011I have a class and method exposed to a client asp.net app. The class looks like
<DataContract()> _
Public Class Class1
Private v_string As String
Private v_integer As Integer
[code]....
The method is declared as
<OperationContract()> _
Function GetStuff(ByVal bar As Class1) As String
In the client code I create an instance of Class1 and set the values for v_string and v_integer, but using Wireshark to look at the xml being sent to the server only a value for v_string is being sent as part of Class1. I'm guessing this is because it considers the value of v_integer to be null/not set. Here is an example of the client code.
Dim MyService as New Service1.ServiceClient
Dim test as New Service1.Class1
test.P_integer = 1
[code]....
how different types are passed/used since Integer is a intergral type and String is a class, but can't seem to work out what to do to fix the problem.
