I need to convert the following C# code to VB.NET:
public bool TryGetRewriteMatch(UrlContext url, out RedirectMatch match)
{
// NOTE: Normally this would use regular expression matches, cached database

However, I need to reference Url and ProductID in the function and I don't know how to pass them as parameters or get their values from the original function.
I'm program to handle ftp multiple file transfers. What I had in mind was to create an array for each type of file I need to process. There are 8 file types each needs to be transferred to a unique host.
' Each array contains in order: FILENAME|SOURCE PATH|DESTINATION PATH|HOST|USERNAME|PASSWORD
Dim arrA() As String = {"*a*.dat", "/destpath1/", "host1", "id", "pass"}

Sometimes it is useful to take a method call, complete with parameters, and turn it into a MethodInvoker which will invoke the indicated function with those parameters, without having to specify the parameters at the time. At other times, it's useful to do something similar, but leaving some parameters open. This type of action is called "Currying". What is the best pattern for doing this in VB?
It's possible to use lambda expressions in VB 2010, but lambda expressions aren't compatible with edit-and-continue, and the closures they create can have unexpected by-reference behaviors. An alternative approach is to define some generic methods such as shown here:
[Code]...
that is the mechanism if a delegate is created from a struct member function? It appears the delegate gets its own copy of the struct, but I don't know whether that copy is boxed or unboxed. If it's not boxed, replacing CurryAction0 and CurryAction1 with structs would avoid the need to allocate a CurryAction0 or CurryAction1 as a separate heap object when creating the delegate. If it's going to be boxed, though, using a struct would add the overhead of copying the struct to the boxed instance while not saving anything.
I'd like to create a function myFunc with one parameter, which is a delegate. I should be able to call it with a delegate as parameter.E.g.[code]But how do I code myFunc, in other words, how do I enable myFunc to have it passed a delegate so that it can be called using myFunc(addressof test Func)?
View 4 RepliesI have a Dialog Box that creates a Link Label for each item in a list.When one of those LinkLabels is clicked the DialogBox raises a LinkClicked event.Before, I was using code like this in the Form that was instantiating the Dialog:[code]But I don't like that for several reasons.What I want to do, and what I thought would be straight forward, was to pass the AddressOf the UserClicked PoLink Method into the ShowClickableLinksDialog Constructor and do an AddHandler within the constructor and also assign the Delegate to a Property on the Dialog so as to RemoveHandler when the Dialog is Disposed.[code]But I get a squiggly on the tempLinkClickedEventHandler after the AddressOf Operator saying: "AddressOf operand must be the name of a method (without parenthesis)"I don't get it.I've played around with a number of permutations and can't get what I feel ought to work, to work.

I have a form with 2 dateTimePickers and a SHOW button which gets data from an sql server database and displays it in a DataGridView. this works ok. I also have an EDIT button which brings up another form with textbox and comboBox controls displaying this one record. I want to be able to click in the DataGridView to select a Name and then click on the EDIT button to bring up the selected record. I don't know how to pass the ID as a parameter to this second form. Apart from that the EDIT button works, in the sense that I hard coded the ID (32 or 35 etc.) and it brings up the appropriate record. But how do i pass the selected ID. [Code]
View 2 RepliesI have a DataSet1.xsd This is connected to my access DB through OleDB. the DataSet Designer is stating that my column in my table is of type Double. Which is true when I verify it by opening Access and viewing that same column in my table.
I need to pass a parameter to my fill query so that on formload it populates the controls. I create the parameter in the dataset designer and give the paramter a name and specify the proper data type.
I edit the query to include the parameter.
on form load the generated code from the dataset designer inserts the fill command for the table adapter but doesn't include the parameter data, so I manually insert the data to be passed to the parameter.. This is where I get an error stating that datatype mismatched..
However the datatypes are correct.
[code]This works fine and passes 8 parameters into the sysimp.bat file. The problem is if I try to pass in a value that has a space between the text then it will treat it as two parameters rater than one.So if P1 value is for example "Hello World" then when passed into the bat file it will assign "Hello" to P1 & "World" to P2. Is there a way to wrap the text in the parameters or should this be done in the .bat file?

I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.

I have a LINQ query:
VB
Dim Db = New MyDataContext
Dim Qry = From cust in Db.Customers
Select cust.ID, cust.Name
And I want to pass it to a function to filter it, like this:

VB
Sub FilterAnyQuery(ByVal AnyQry As iQueryable, AnyField as ???)
AnyQry = AnyQry.Where(AnyField = "somevalue")
End Sub
How can I pass "AnyField" to the Sub and make the LINQ "Where" clause work?
