Use The ToString Method And A Counter To Concatenate A File Name Into A String Variable From The Image.FromFile Method?
Dec 18, 2010I have nine pictures that I need to animate -I need to use the ToString method and a counter to concatenate a file name into a string variable from the Image.FromFile method. Once the counter reaches its maximum value, and the last picture is displayed, the counter should be reset to zero or one depending on how the first image file has been name. Also a static counter variable should be incremented in the time routine. what I have so far -- I know what I have to do; however, I just do not know how to code this properly.. Right now I have this going thru a button procedure but it needs to go through a timer.

View 3 RepliesHow To Create A Public Instance Method
Aug 21, 2009I'm working through a book that does not provide a lot of example code and what it does provide is in C#. The book refs vs 2005 but I'm using vs2008. The author asks for the user to create a solution with two projects, one winforms and the other a class library (called DependentAssm). The class library is added as a reference to the winforms project In the class library, he asks one to create a new class called SayHelloComp. The project created a file called class1.vb, and a class called class1 which I renamed to SayHelloComp. I left the file name alone, that's ok right?

Nov 4, 2010I have been thrown in at the deep end with an existing VB.NET project at work. I have never used VB.NET before so I am struggling a little. Does anyone know how to solve the following.I need to pass an instance to client side and then pass it to a shared method in order to access instance methods from when the shared method.The starting point is a fileupload control within the HTML of my Contacts.aspx file:
<asp:FileUpload ID="DocUpload1" runat="server" onchange="CallMe();" />
The onchange event calls a javascript method, see below, this uses AJAX PageMethods to called a Shared method in my code behind This is the script code which is in my Contact.aspx file

If anyone knows the solution please could they update the code as I probably won't be able to understand if you just give a description. I just hope I am along the right tracks.
Use Extension Method On System.Object Instance?
Jul 12, 2010Can I make an Extension method for all the subclasses of System.Object (everything)?
Example:
<Extension>
Public Function MyExtension(value As Object) As Object
Return value
End Function
The above functions won't work for object instance:UPDATE The problem seems to occur only in VB, where members of object are looked-up by reflection (late-bound).UPDATE AFTER ANSWERED.FYI, as vb has an advantage that C# lacks that is, members of imported Modules are imported to the global scope so you can still use this functions without their wrapper:Dim myObj2 = MyExtension(myObj1)
VS2010 - Cannot Find Method On Object Instance
Nov 19, 2010Basically, I've got this plugin-based application I've used all the time in VS2008 flawlessly. In my current project (VS2010 by the way) I wrote a plugin for the application and whenever I try to use an instance of a particular class (in an external dll) from my plugin, I get an error.
I tried watching the instance and I got the message:
"Cannot find the method on the object instance."
in the watch window. This has never happened before! I also found that some of the extension methods in the plugin does not work.
Wcf - Execute A Method On An Existing Process Instance?
May 16, 2012I have a windows service that I have been writing in Vb.Net. As part of this service it calls a class that has a long running Process.I can execute commands to this process when I want to via the ServerCommands() class within the service, however I want to call these remotely. Possibly from a website or click once WPF application.
For this I have used a simple Tcp.Ip WCF example, and have verified it as working correctly.
This called OnStart()Private _serverCommands As ServerCommands
Protected Overrides Sub OnStart(ByVal args() As String)
Add code here to start your service. This method should set things
in motion so your service can do its work.
[Code]...
It appears that in debug _serverCommands is Nothing when it should be running.How might I go about ensuring any command I execute through WCF communicates with the running instance instead of creating a new ServerCommand() instance??I haven't tried WCF before, so I might be hitting a dead end... however I'm sure its possible.
.net - Prohibit An Instance From Calling Shared/Static Method?
Aug 27, 2010Is it possible to prohibit an instance of a class from calling a shared/static method?
For example:
I want to allow this:
ClassName.MethodOne()
But I want to disallow this:
Dim A As New ClassName
A.MethodOne()
The reason this is desirable is that in this case it is semantically confusing if an instance can call the method.

View 5 RepliesClass - Call A Method In The Default Instance Form Instead Of Instantiating Another?
Nov 15, 2009When an instantiated class calls a method in the parent form class, VB.NET starts a new instance of the form class instead of calling the method on to the active one.How do I tell it that I have just one instance of my form class, or that I don't want to create a new instance of the form and just call the method on the already active form?
View 2 RepliesMoving Large Instance Method To Shared And Creating Stub?
Jun 5, 2011If I have a very large function/sub in a class that is an instance method (i.e., not Shared), do I gain or lose anything by moving that to a shared method and then declaring a small stub method for the instance use?
I.e., I go from this:
Public Sub MyBigMethod(ByVal Foobar As String)
If String.IsNullOrWhitespace(Foobar) Then
Throw New ArgumentNullException("Foobar")
End If
[Code] .....
My thinking is I save on memory size per each instance of the object. Because each instance only has to lug around the stub method which handles calling the shared version and passing an instance of itself to the shared method so that it can do whatever it needs to do. But I'll wager that I sacrifice a very teensy amount of speed because of the added function call overhead.

.net - Create A Variable Of An Instance Object Of A Class At Runtime?
Sep 29, 2011I am trying to create new variables inside a class after creating its object at runtime. The problem is that I don't know the variable names or the value beforehand so I have to create the new variables at runtime.
[Code]...
This is a more elaborate explanation of my code. If you observe that in the Eval function I have tried to evaluate Fval(abc). Now the object array abc is not declared in the Test class because it existence is not known beforehand. What I want to do is create an object array abc of length 2 and populate it with some values and when Fval(abc) is called then then the value of index 1 should be the return value of Eval fucntion.
.NET : Runtime Is Initializing A Variable To An Instance Of The Wrong Class?
Jul 26, 2010I've got some code that looks like this:
If ediFileGroupAbbr = "NIPDSINV" OrElse ediFileGroupAbbr = "WWPDSINV" Then
Dim p As New PrivateBillingAdapter_ForN(ediFileGroupAbbr, businessLocationID, mode, EDIJobItemLogID, BusinessUnitID)
Return p.ProcessEDI(True, False)
ElseIf ediFileGroupAbbr = "FOPDSINV" Then
[code]...
to which I'm passing in a value of ediFileGroupAbbr = "FOPDSINV". But the code is executing as if it's dropping into the third condition (p is a PrivateBillingAdapter). So I've stepped into the code and, sure enough, it drops into the second condition. BUT, if I step into the execution of the constructor, the debugger jumps to an odd place in the code - sort of the middle of a method and not on any actual line of code.A couple clicks and it hops back out of the constructor, still in the second block of code. But if I mouse over the variable p to see it's type, boom, its a PrivateBillingAdapter (from the third block).Like I said, something is clearly wrong but I don't know what. I've tried rebuilding several times but with no new results.This is VS2003, framework 1.1 with VB.NET.
C# - Access A Shared/static Member Through An Instance Variable?
Mar 3, 2011Here's an example of what I'm talking about...
Public Class Sample1
Public Shared Function MyValue() As Integer
Return 0
End Function
Public Sub Code()
[Code]...
Me.MyValue gives a warning in VB.NET and (the equivalent code gives) an error in C#. Is there a particular reason for this? I find it more intuitive/natural to access the shared function using 'Me.MyValue' - but I avoid it to keep my warnings at 0. Did someone else just decide 'Nah, it makes more sense to do it the other way' or is there some technical reason I don't understand?
EDIT: I was thinking of it wrong, more like a 'sub class' in OOP. Even if something is declared in the base class, you access it through the instance you have. But that relationship is not the same with shared or static.
C# - .NET Generic Class Instance - Passing A Variable Data Type
Jun 2, 2010I'm tyring to pass a variable data type to a template class. Something like this:
frmExample = New LookupForm(Of Models.MyClass) 'Works fine
Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine
frmExample = New LookupForm(Of SelectedType) 'Ba-bow!
frmExample = New LookupForm(Of InstanceOfMyClass.GetType()) 'Ba-bow!
[Code].....
I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either.
(How) can I create an instance of a dynamically typed repository at runtime?
C# - Refactor Data Contracts In WCF Services?
Feb 11, 2010We have lots of WCF services that are only used by our own code; the code that uses them is mostly in the same solutions files that contains the services.
However they do not use a shared assembly for the contracts, so each time a data contract is change the reference to the service has to be updated by hand in all projects that use the service. (Then the code needs to be fixed up by hand)
So how do I do a simple refactoring like renamed a data item in a data contract?
Is there a way to update all references to services in a single solution with one command, rather then having to click on each reference in each project?
