View 1 RepliesPhp - C# Or .NET Equivalent To Scope Resolution Operator?
Nov 22, 2011I am porting php code to vbnet (i'm a little better at vbnet than c#). In the php is the scope resolution operator.
Here's the bit:
$args = phpZenfolio::processArgs( func_get_args() );
Equivalent in c#/vbnet?The whole function is the following which i gues is equivalent to the sub new in vbnet.
public function __construct()
{
$args = phpZenfolio::processArgs( func_get_args() );
$this->APIVer = ( array_key_exists( 'APIVer', $args ) ) ? $args['APIVer'] : '1.4';

.Net CodeDom - Create Delegate With AddressOf Operator Equivalent?
Apr 25, 2011Is there a way to create a delegate instance in .Net using CodeDom? I want to generate something which looks like the following:Dim myDelegate As someDelegateType = New someDelegateType(AddressOf implementingMethod)Below is more info on the context...Original Question:I am using CodeDom from the .Net framework (v3.5 if it matters) to generate a class. One of the classes defines a delegate method which in VB.Net looks like:Public Delegate Function filterByIdDelegate(ByVal obj As Object, ByVal id As Integer) As BooleanI then have a method which will provide the implementation:Private Function filterById(ByVal obj As Object, ByVal id As Integer) As Boolean Return (obj.ID = id)nd FunctionHere's the problem; how do you create an instance of the delegate (using the equivalent of AddressOf for VB.Net)? I am currently doing this (<filterByIdFunctionName> is a string holding the name of the delegate function, `' is the name of the delegate field):
Dim getFunction = New System.CodeDom.CodeMemberMethod()
With getFunction
'Declare delegate instance

Error: Option Strict On Disallows Operands Of Type Object For Operator '='. Use The 'Is' Operator To Test For Object Identity
Jan 27, 2010I am tightening up my coding with the Option Strict set to ON. It has now produced alot of errors. An example of this is:
If AllocatedDGV.Rows(i).Cells("RoomNumber").Value = RoomsAvailableDGV.Rows(j).Cells("RoomName").Value Then
It gives me the following error: Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity.
Option Strict On Disallows Operands Of Type Object For Operator Use The 'Is' Operator To Test For Object Identity
Apr 6, 2012I need to write an interface to get data to/from our data files.
We have a low level class that holds field values for each record read from the files.
This just holds two values, the value read from the file (DBValue) and the updated value that may need to be written back to the file (CurrentValue).
These values may be any of the standard value types (integer, date etc) or a string.
Either value (DBValue or CurrentValue) may be null if not defined.
I have written the class to manage this data which works fine while option strict is NOT on.
But we have an office policy of having option strict on all the time.
When I put option strict on, my object value comparisons fail with the error: "Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity."
Question, how should I change the following code to handle option strict on ...
This is all running on Visual Studio 2010

Pass In An Operator?
Jul 4, 2010Is there any way to pass in an operator in VB.NET? I'm looking to reduce my lines of code and for two functions there is literally only an operator that is different.For example, I have two functions, Darken and Lighten. I'd like to get to a single function with as little code as possible. The only difference are Greater Than and Less Than operators.
Function Darken(ByVal clr1 As Color, ByVal clr2 As Color) As Color
Dim newR = If(clr2.R < clr1.R, clr2.R, clr1.R)
Dim newG = If(clr2.G < clr1.G, clr2.G, clr1.G)

View 2 RepliesUsing The 'And' Operator Properly?
Apr 8, 2010In the project�s btnReadNumber click event handler, replace the code in the try section of the try/catch block � the two if statements and the unconditionally executed code � with one if-else statement that performs the same tasks. Use the And operator to write the if-statement�s condition.What I don't understand is how am I supposed to use the 'And' operator so that when I insert a number between 32-16384 in the text box it'll allow it to go through and at the same time not allow any numbers lower than 32(lower_bound) and higher than 16384(upper_bound) to go through.I've use the 'Or' operator and that was simple, but with 'And' I'm not understanding it.Remember it has to be with the 'AND' operator. I bold the area where my problem is at. It's obviously not the right answer, but that's where I was stumped.
Dim sum As Integer = 0
Const upper_bound As Integer = 16384
Const lower_bound As Integer = 32

What's An Example Of An Overloaded 'And' Operator
Nov 21, 2010So Google's not a good choice for looking up examples for overloaded operators like "And" or "Or", because it tries to parse them as operators to the search query itself. MSDN also provides no examples of how to implement an overloaded And operator, so I'm not certain how to properly overload it for my project.Does anyone have an example of "And" at minimum? "Or" or "Xor" (or any others) would be a bonus. I'm not certain if I need to overload these operators in my objects just yet, as I'm still building them out and haven't planned beyond just yet. But having examples around that might get indexed by Google will probably help save the sanity of a lot of people...
