There are two answers here Constructing an object and calling a method without assignment in VB.Net that should help.
- Use
With ... End With
- Use
Call
I think you're having an issue because you're trying to use the C# style of creating an instance of an object without assigning it before chaining a method call.
Your code becomes:
Dim name As String = "hello"
If CType(My.Application.OpenForms(name), Faker) Is Nothing Then
With New Faker() With {.Name = name, .Title = String.Format("{0} - ID:{1}", "hello", Me.ClassClient.ClientAddressID)}
.Show()
End If
Or
Dim name As String = "hello"
If CType(My.Application.OpenForms(name), Faker) Is Nothing Then
Call New Faker() With {.Name = name, .Title = String.Format("{0} - ID:{1}", "hello", Me.ClassClient.ClientAddressID)}.Show()
End If
