Verify A Method Was Called Exactly Once Using AAA Syntax
Sep 26, 2010
I am trying to use the AAA syntax in Rhino Mocks with VB.Net to validate that a method was called only one time. I can't seem to get it right. With this code, if the repository is called twice, it returns nothing on the second call, and the test passes. I would have expected the test to fail when VerifyAllExpectations was called.
<TestMethod()>
Public Sub GetDataCallsRepositoryOneTime()
Dim repository As IDataRepository = MockRepository.GenerateMock(Of IDataRepository)()

I have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

I'm working with a VB.Net page which calls a web method from JavaScript, this was working upto a week ago and now for some reason is not working.
Firstly my page generates a list of items that can be clicked, The line that does this is:
TicketHTML = TicketHTML + "<td><img src='../images/delete.png' Class='imgTicketClose' alt='Delete Task' onclick='DeleteTicket(" + row("id").ToString() + ")' /></td></tr>"
I know this is working as when the item is clicked I get a javascript popup so I would assume the problem is not here.
Now my Javascript:
function DeleteTicket(ticketID)
{
var answer = confirm("Do you really want to delete this task?")
[Code].....
EDIT: Could anything in the web.config file be preventing page methods from executing? I have just noticed this happening with a completely seperate web method and have checked the integers being passed into the javascript with an alert() and they are all valid

I have a class which i realized will not always correctly instantiate and as a quick fix, i figured i'd subclass it and shadow a few methods so that the program can continue to run without exploding. When i run the software, calls to the methods resolve to the base's implementations and not the subclass. I'm using VB.NET with .NET 2.0. Here is an example of what i'm trying to do[code]....

When I put a breakpoint in a method I'm calling from a lambda expression, the breakpoint is never hit. When I move the method call outside the lambda, the breakpoint hits.
For example:
Function IncrementAll(ByVal items As IEnumerable(Of Integer)) As IEnumerable(Of Integer)
Return items.Select(Function(i) Increment(i))
End Function
[Code]....
If I call IncrementAll, the breakpoint in Increment does not get hit. Is there a way to make VS 2008 stop on these breakpoints? I hate the thought of rewriting all my LINQ into loops just for debugging.

I create a UserControl (TableWithFilter.xaml) with a dependency property (source). The UserControl is a Table with a source property for the different items. I created the XAML and set the source property via the XAML Binding. So far so good.
But if the value of the dependency property is changed, the defined callback method is not called. Therefore I cannot update the entries in my table. Has anyone an idea why the callback method is not called?
Here is the definition of my property in the class "TableWithFilter":
Public Shared ReadOnly SourceProperty As DependencyProperty = _
DependencyProperty.Register("Source", GetType(List(Of TableViewItem)), GetType(TableWithFilter), _
[Code]....
If the attribute "ContentList" is changed I expet that the "ChangeSource" method in the TableWithFilder class is called. But this is not the case. After I changed the ContentList attribute, I Raise the following Event:
RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("ContentList"))

How do I force the Visual Studio compiler to generate an error when a required method is not being called in the constructor of a child class? Like when you edit the form designer code, the compiler complains when InitializeComponent()isn't the first call in the constructor of a form. Is this even possible in VB.NET?

I'm trying to write a method that is called from a variety of forms at load. So with a Form1 load event I would call the following:

DrawVerticalStringFromBottomUp("Hello", testpoint, Me)
The DrawVerticalSTringFromBottomUp Method is as follows:

When I call the code at a form's load event, nothing happens. When I call it from a button click after the form has loaded it works! I know this should be called from the paint method, but that doesn't suit my purposes.
way to make this work from the form load event?

Using Excel Automation classes I am seeking to save an Excel file as a delimited text file. The examples given in the MSDN library refer to versions older than Express 2008 with (apparently) different syntax options for FileFormat.Based on the snippet shown, I get a COM exception error (800A03EC). Other variations produce the same error.
Am I improperly applying the Automation features?

It gets down to the last relation that I made called "ProdDet" and jumps out of the whole method. The error message says the following:
System.ArgumentException: These columns don't currently have unique values.

i was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]

I have the following line of code in my program:
JCL_History.Enqueue(JCL_History(I))
This JCL_History object is basically a Generic.List encapsulated in a wrapper and has the following method:
Public Sub Enqueue(ByRef value As String)
If Members.Contains(value) Then
Me.RemoveAt(Members.IndexOf(value))
[Code].....
In my testing I have 2 items in this JCL_History list. When I call that first line of code I posted (the one that invokes Enqueue) with I = 1 I expect the first item to be shuffled to the bottom and the second item to be shuffled to the top.
After the thread returns from Enqueue I notice that this is exactly what happens to my list, HOWEVER if I hit the "step_in" button after the execution of Enqueue I go into the Default Property's set method where Index = 1 and value = and it screws everything up, because the item that got shuffled to the end (index 1) gets overwritten by the item value shuffled to the top.
So basically the set method on the default property is getting called at what I think to be a completely ridiculous time. What gives? By the way I'm running VS2005 on XP.

Can you look at my coding and let me know what I'm missing or doing wrong?I have a SSRS report that is called from a ReportViewer control and the ProcessingMode for this control is Remote. The report also has 1 parameter in it's DataSet.In the code I placed a MsgBox to make sure the code is finding the parameter and returning the parameter name. I am trying to stick the value of 10 into the parameter for playerID 10. Data for this player does exist.
I believe I need to add some more code to make this work but I'm not sure what else to add.
When the code executes the report is displayed but no data is shown in the report.

I recently found an awesome tool called "Freemind" that is called a 'mind mapping' program. It's similar to MS Visio but way cooler and more automated.I reeeallly would like to integrate this into a VB.net Form, but how?
Has anyone seen or heard of mind mapping inside VB.net before? Are there programs out there already that work with VB.net or anyone have an example they have seen / built that works?
