The following image or RTF file illustrates how I'm trying to transform an input Byte array into an output array of Booleans. This is basically what I have listed below. figure out how to get from one array to the next while shifting values of bytes within 8 byte groupings to shift low order to high order or vica versa. What I mean by that is best seen by looking at the illustration of actual input an required output. The reason for this is that the hardware devices have registers and the display which can be seen in the links above needs to convey the disabled sensor cable cell locations.

I have this function:
Public Sub DoStuff(ByVal type as System.Type, ByVal value as Object)
End Sub
The 'value' argument is always an array of the same type as 'type'. How can I loop through the values of the array?
I'd like to be able to do something like this:
DoStuff(GetType(Integer), New Integer(){1,2,3})
Public Sub DoStuff(ByVal type as System.Type, ByVal value as Object)
//Strongly types arr as Integer()

I'm working on a home project using DirectShow.Net. to learn some VB.net. Most of the examples I've found have all been in C# so I'm looking through code for ideas and converting where I need to. I keep stumbling upon these declarations and I'm unsure how to convert it to a VB.Net statement.[code]Then the second part seems to be assigning the value but as its made up of two parts im unsure how that works?

I'm programming a basic slot machine in Visual basic, and want to use a for loop to randomly choose the image for each slot, display the image in each slot, and change the slotName variable (so I can check later on which symbols are in the slots) for each slot. The problem I'm finding with a for loop is that the variables and objects for each slot have different names (slot1Name, slot2Name, slot3Name, lblSlot1, lblSlot2, lblSlot3, etc). Is there any way I could have could something like:
currentSlotName = "slot" & i & "Name"
This is the code at the moment, this code is repeated (with different variable and object names), for each of the 3 slots, which is pretty inefficient.
' Randomise numbers and assign images to slots based on random numbers, if the hold isn't on
' Slot 1
If Not held1 Then
slot1Value = Int(Rnd() * numbersGenerated + 0.5)
Select Case slot1Value

Here's my problem :
Let say I have a variable called A
Which value is 100 ( A = 100)
In a form, I have a textbox, where I want to enter a variable name
textbox1.text="A" for example
Then I want to display the value of that variable
msgbox (somefunction(textbox1.text)), which will popup 100
I read some info about Reflection, but they all seems to refer to controls and not simple variable

I am developing an application which initially allows the user to browse and select a save location. The selected path is assigned to a public variable which is used with concatenation to crate folder for saving user input data. How can I change the path string to a constant so the user can run the program again without having to run setup routine unless they want to change the save location?

if i generate a label dynamically i can change the text as followed, variable is a string: Form.Controls(variable).text = "test" I now have a sub that will create some and will get some information out of arrays. I have a lot of them. I only want the function for tat specific array. I do not want a case or if. Thats why i was wondering if i can use a variable in the array variable. [Code] But instead of TestArray being hard-coded i want it to be replaced with Shelf. So whatever gets send into the sub will change the array that i'm using. Is that possible some how or is the way totally wrong?

I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).

I'm writing reports in Report Designer (VS 2008), and I've reached a point where I have to circumvent the restrictions on using aggregates in groups. I believe this can be done by utilising custom code, which is written in Visual Basic as far as I know (not sure what version though).
I have a dynamic number of "Pools", which each contain "Models". Each Model row needs to set the Pool Multiplier to the maximum of the current multiplier and proposed multiplier. The Pool row (parent group row) then needs to get the Pool Multiplier.[code]...

i want to declare an array with a name that is the value of a variable. I need to do this because i want to create arrays from a text file that i'm reading.Basically, if someone could make this work then i should be able to change it to fit my use.
Dim var1 As String = howdy
Dim var1() as Integer
In this case i'd like to be declaring an array with the name 'howdy' that stores integers. In reality i'm looping a bunch of read names and would like to create an array for each name i read- but i'm quite capable of sorting the rest.
