What Is LenB Actually Doing On None String Parameters
Feb 24, 2009
I have this bit of code that is being converted from vb6 to vb.net. I need to know what LenB is doing in this bit of code.
Dim singleValue As Single 'var for conversion use(4byte -> 1single)'
Dim bytes() As Byte
Dim valueB() As Byte 'this gets set elsewhere and is redim-d to its size'
[code]....
Am I right in thinking that bytes is always ReDim'ed to the same size? By the looks of it 4 elements.Why then use LenB to ReDim if you could just use a number? And why ReDim in the loop at all?

What is LenB? What does it mean? I have recently converted a project form vb6 to vb.net and it is riddled with this error 'Name LenB is not declared'.[code]...

I've stumbled upon this code:
var knownSeparators = new[] { "\", "/", "|", "." };
return knownSeparators.FirstOrDefault(path.Contains);
where path is a string and the return value should be a string as well.
Allthough path.Contains' intellisense suggests a parameter, it works fine without one.
How does this work exactly? Is there any way to copy this behavior in vb.net?

In the Expression builder window in SQL Server Reporting Services 2008 R2 under Common Functions -> Text -> Item, there is an expression called Filter.This appears to correspond with the Strings.Filter method in the .NET framework. The description of Filter is as follows: Returns a zero-based array containing a subset of a String array based on specified filter criteria.The Example is as follows:
=Filter(Parameters!MultivalueParameter.Value, "3", True, CompareMethod.Binary)
The example and description imply that you can inspect a multi-value parameter to see if at least one of the selected values is equal to the Match parameter. I haven't been able to get this to return anything other than #Error which implies the multi-value parameter is not a one-dimensional array. Parameters!MultivalueParameter.Value.GetType().ToString() returns System. Object[].
how to get this to work? I'm using the following work around to check if values were selected in the multi-value parameter:
=IIF(InStr(" " + JOIN(Parameters!MultivalueParameter.Value, " ") + " ", " 3 ", CompareMethod.Text), false, true)
I would prefer to use the Filter function if it supports this kind of check.

My program uses parameters from the calling program in this format
parameter1/parameter2/parameter3
parameter2 is a datafile path which may sometimes have a space like :
C:Program Files est company
I did this as a work around
Sub Main(ByVal Args() As String)
dim cArgs as string=""
Dim J As Integer
For J = 0 To Args.Length - 1
cArgs = cArgs & " " & Args(J)
Next
And then used the string split function. Is there a proper way to work with spaces?

For example, assume that in my assembly, in Namespace A, Class B, there is an instance method with the following signature: void Test(string someString, int someOtherParm, string someOtherString ); This method is called multiple times, from multiple places in the assembly. I would like to be able build a list of all invocations of this method and the value of the someString/someOtherString (assuming they are hardcoded). In other words, I like to extract a list of calls like the example one below, if they happen in the assembly somewhere: Test("some text", 8, "some other text");

I'm writing a query to select all records that has any part of parameter. I have one table called Employees. Some people have name like this: John David Clark If the parameter is
[Code]....
I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

since it saves my coding time. So which is better to use? Which is safe to use? Does it improves performance?

When I have Option Strict ON in my project, the IDE tells me that "Option Strict On disallows implicit conversions from 'System.Data.ParameterDirection' to 'String'." How can this be, since I'm using their built-in enumeration for the SqlParameter direction.

I've got a project in c# which is making use of another project written in vb.net. I am currently able to modify both.I've got a method in the VB project like:
Public Sub MethodName(ByVal param1 As String, ByRef param2 As String)
param2 = param1 + 1
End Sub
I am not able to call this method using the out keyword from C#:
public void CallOtherMethod()
{
string param1 ="test";
string param2;
provider.AddTransaction(param1, out param2);
}
Shouldn't the ByRef keyword in VB.Net have the capabilities of both "ref" and "out"?

A fast-food vendor sells pizza slices ($1.75), fries ($2.00), and soft drinks ($1.25).Write a program to compute a customer�s bill.The program should request the quantity of each item ordered in a Sub procedure, calculate the total cost with a Function procedure, and use a Sub procedure to display an itemized bill. A sample output is shown in Fig. 5.26.Coded it out but when I try to break it down to separate functions I keep getting:
Error1Argument not specified for parameter 'CalculateFries' of 'Public Function CalculateTotal(CalculatePizza As Double, CalculateFries As Double, CalculateSoft As Double) As Double'.
Error1Argument not specified for parameter 'CalculatePizza' of 'Public Function CalculateTotal(CalculatePizza As Double, CalculateFries As Double, CalculateSoft As Double) As Double'.
