Public Class ABC
Public Sub Foo()
AA.Bar(nothing, Sub()
End Sub)
End Sub
End Class
I feel confused at the second argument of function AA.Bar, this argument is specified as a Sub/End Sub procedure.What is the function AA.Bar's possible definition looks like?An event? Delegate? Pointer like?...Where can I find the latest VB.NET Grammar Specification?What are the new features in VB.NET 4?
I made this procedure re-use a select query:
[code..]
And I use it like this if I would want the selected value placed in a textbox and it works fine
[code...]
However if I want the value to be passed in a string like so:
[code...]
The string ends up having an empty string value. How do I assign the value I queried to that String?
I'm using EPPlus 2.9.0.1 with Visual Basic.I have a DataTable with 35 Rows and 4 Columns and the code below:[code]When method 'LoadFromDataTable' is called, I get an ArgumentException (Negative row and Columns numbers are not allowed). I don't have negative numbers in row or column numbers, as far I know.
View 1 RepliesWhy does this:Private [Function] As Func(Of Double, String) = Function(ByRef z As Double) z.ToString
gives the following error:Nested function does not have a signature that is compatible with delegate String)'.
While this:Private [Function] As Func(Of Double, String) = Function(ByVal z As Double) z.ToString
Does not? (The difference is ByRef/ByVal)
Furthermore, how might I implement such a thing?

Anytime an accent mark is used in the plain text i get a "Procedure call or argument is not valid" error. So trying to encrypt "Vigene cipher" for example will not work.

View 2 RepliesI'm making an application that requires me to perform speech recognition from a wave file that contains some speech. I know what the words in the wave file could be.So, I need to compare these words from a small custom grammar/dictionalr instead of a whole built in large vocabulary.
I have done the recognition part with the default system large vocabulary but now just need to use my own vocabulary.
Suppose that the words that the user can say are:
Hello
hundred degree celcius,
USA,
Yes,
No
Then, how shall I write my XML Grammar? I suppose that if I use the limited small vocabulary, then my accuracy of recognition would increase. Right now, ive a wave file in Microsoft Mary's voice saying "Hello". But with the large default vocabulary its recognising it as "All though". Is my assumption correct that with the above mentioned 5 words in the vocabulry, it will recognise it as Hello only?
Ive been looking at the internet but can't find solution to my specific problem regarding making a simple grammar. In most documents its mentioning using external grammar and about several of the attributes posssible, including sementics, etc, etc. But my vocabulary is not very complicated or difficult. And I don't want to get into too much detail at the moment as I would be deviating from my project itself..
So using the following code:
Grammar = RecoContext.CreateGrammar
Grammar.CmdLoadFromFile("C:CustomGrammar.xml")
What should be the content of the CustomGrammar.xml?

View 18 RepliesThe instructions are as follows:
1. Write a Visual Basic Console Application.Inside the main procedure call a function procedure to input and return a value for a double variable called x, the width of a right triangle.Inside the main procedure call the same function procedure a second time to get a value for a double variable called y, the height of a right triangle.
2. From the main procedure call a function procedure which calculates and returns a value for the hypotenuse equal to the square root of (x squared + y squared).You will have to pass the values of x and y to this function procedure.The procedure should calculate and return a double type value.The value that is returned by this function procedure should be equal to the square root of (x squared + y squared).
3. Also from the main procedure call a sub procedure to display the values of x, y, and the hypotenuse.
In a tic tac toe game I am making there are two blocks of code that are identical except that they access different arrays:[code]Arrays plyrTaken and plyrPairs are used in the first block and cmptrTaken and cmptrPairs are used in the second. Is it possible to wrap these blocks into one Sub Procedure passing the different arrays when the procedure is called?

I have a problem when trying to send a POST request. The sending method looks like this:
Public Sub SendXML(ByVal file As String)
Dim reader As New StreamReader(file)
Dim data As String = reader.ReadToEnd()
[Code]....
Now looking at this I suspected that it was due to the fact that the server does not accept POST messages. But some other reading suggests that the the URI [URL] has been generated with a proxy and should be /Request so the line should read POST /Request HTTP/1.1
So what would be the common reason for this? And if it is a proxy problem, how is it sorted?
As asked below, I have created a new question for the more specific request. Changing absolute URI to relative in HTTP POST header
I know that you cannot specify a constructor in an interface in .Net, but why can we not?
It would be really useful for my current project to be able to specify that an 'engine' must be passed in with the constructor, but as I cant, I have to suffice with an XML comment on the class.
are nested functions allowed in visual basic?
View 9 Repliesi am currently having two problems with this assignment. The program allows the user to add new students to a listbox with a unique Id, lastname and test average. When adding a new student to the listbox, part of the assignment is to not have duplicate students added. I am currently stuck at trying to figure that out. I have figured out how not to have duplicate courses under the course information form but when trying similar code for adding a student i cant get anything i try to work. the next problem is when searching for a student from the list and clicking on the Course Information button, the course information added for that student needs to be displayed. My problem is getting the student searched information to show up right, but if i add three students and search for the first one i added and click on course information button it only shows the last student i added. this is my code for the whole program
