I am looking to convert an integer into a boolean array where each item in the array corresponds to a bit in the binary representation of the integer.
MyInteger = 3 '011 in binary
to
MyArray(2) = False
MyArray(1) = True
MyArray(0) = True
Also is there anyway to assign a value to an Integer in binary or hex (like MyInteger = 1010b or MyInteger = A7h)?

View 8 RepliesI got to a snag recently in the program. I know exactly what is going wrong, and I know exactly what will fix it. However, I do not know how to code what I need.

So as you can see, I need to convert a binary string into an integer so it will work properly. Everything else is fine, I've tested it out a lot and done a lot of debugging, even manually, and I'm sure everything will work. All I need is the code to convert it.
Is there an easy way to do this in .NET.I see the Convert.ToXXXX, but no Convert.ToBinaryString.

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'm just writing a bit of code to compare an id of integer with an id of integer? for example:
Dim id As Integer = 1
Dim nullId As Integer? = Nothing
Dim areEqual As Boolean
areEqual = nullId = id
When I try to compile the code I get a compiler error: Option Strict On disallows implicit conversions from 'Boolean?' to 'Boolean'. Whilst it's very simple for me to work around this, I was hoping that someone might be able to explain what's going in the compiler to give this warning.
I am trying to read the data from a device on a serial port. I connect just fine and can receive data fine in text mode but not in binary mode. I am using VB.NET express. I am at the point in my code where I know that the device is sending 1056 binary bytes of data. How do I go about storing this is a binary array? After I have the array stored (which I dont yet) I need to go through the array and convert the binary to integers. They are 2byte integers in the format: 8bit MSB|8 bit LSB.
View 5 RepliesI am reading/writing a fixed length header into a stream and I need to do the following in VB:
1. Convert a 2 byte integer (int16) into a byte array
2. Read 2 bytes of a byte array into an integer variable
I have a very simple question about converting a byte array into 16bit integers. I am connected to a device through a serial port. It sent me six bytes which represent three Int16 integers. For example, the byte array is called newRecievedData(5) and has a length of 6.
The manual that came with the device claims that the int Format is 8 bit MSB|8 bit LSB. Does that mean the following?
newRecievedData(0) contains 8 high bits of the first Int16
newRecievedData(1) contains 8 low bits of the first Int16
newRecievedData(2) contains 8 high bits of the second Int16

but VB.NET Express 2008 gives me the error that Error 1 Value of type '1-dimensional array of Byte' cannot be converted to 'Short'.
I am a visual basic developer, I have windows 7 64 bits and Visual Studio 64 bits installed.CAN I DESIGN APPLICATIONS WITH THESE SETTINGS THAT CAN BE COMPATIBLE with 32 bits operating system(example in windows Xp 32 bits)?
View 2 RepliesIs it safe to assume an int will always be 32 bits in C#? The linked question asks whether it is "safe to assume that an int will always be 32 bits in C#". The accepted answer states that "the C# specification rigidly defines that int is an alias for System.Int32 with exactly 32 bits".
My question is this: does this hold true for VB.Net's Integer? Is it safe to assume that Integer will always be an alias for int32?

View 7 RepliesI am interfacing my pc to a device called a MiniBee which is basically a usb digital output adapter to allow electronic devices to be controlled by the pc. So, I need to be able to individually address the output channels of this device, the only problem is the DLL supplied with it will only accept an integer value which represents a binary instruction if that makes any sense. I have basically got 8 public boolean vars OUT1, OUT2 etc that I need to use to turn on/off the outputs by them being set to true/false.
So there are say 8 digital output channels to operate and it has to work like this:
SetOutputs(1) would turn on output 1 and turn all others off
SetOutputs(2) would turn on output 2 and all others off
SetOutputs(3) turns on 1 and 2 and all others off
How to turn my public bool vars into an integer based on what is set to true/false if you get my meaning as there must be an easy way but working it out individually there are far too many possible permutations.

This is probably a really basic (no pun intended) question, but I can't seem to find an answer anywhere.Why does the result of func1 return False and func2 returns True? On every other test I have done, integer 1 is converted to boolean true and 0 to false. Works ok if I just set rtnValue to 1 or 0.
I am working with some VB.Net code that seems to be casting a boolean value to an integer using CInt(myBoolean). The odd thing that is happening is that it returns -1 if the value is true. For example:
CInt(True) // returns -1
CInt(False) // returns 0
Is this common in other languages? I thought that a boolean would be 1 if true and 0 if false. Also, is there a way to make VB assign 1 to true instead of assigning -1?
Is there anyway to customize a variable to use both an integer and a boolean value?For example. I am kind of making a simulation engine and using GDI as a visual aid, I am generating a grid of tiles for objects to be displayed, but I do NOT want to repaint all the tiles just the ones that have changed, so that I can save fps.So I thought if I could set a variable for the "tile number", "how many objects there are on a tile", and a boolean value for whether or not the tile needs repainted.[code]

I have a byte array with 512 Elements and need to get and set a single bit of a byte in this array.The operation must not change any other bits, only the specified one.So if I have a byte like &B00110011 and would like to change the third bit to 1 it should be &B00110111.
Like this:Dim myarray(511) as byte myarray(3).2 = 1 ---> This would change the third bit (start counting at 0) of the third byte to 1 I know it should be easily possible using bit-masking but I don't have the time to try for days to get it working.
Has any one used BITs in VB.NET? If so, do you have code samples? I was looking at SharpBits but I have a VB project that I wanted to use BITS for. Is it possible to use it with my VB.NET program? (.NET 2.0) I was tempted to try to convert each class to VB.NET in the SharpBits.Base folder but figured I'd ask in case someone has headed down this route before.
In case you run across this question. What you can do is in the Sharpbits.Base folder (that you download from codeplex) there is a DLL you can reference in the Bin directory. You can add that into your references to access it. Marking Konrad as answer since he was kind enough to post.
I managed to get sharpbits working with some quick code which I pasted below for anyone who might stumble upon this question. Like I mentioned above add the DLL to your project.
Dim b As New SharpBits.Base.BitsManager
Dim mynewjob As SharpBits.Base.BitsJob = _
b.CreateJob("jobname", SharpBits.Base.JobType.Download)
mynewjob.AddFile("\servershareigfile.zip", "c:igfile.zip")
mynewjob.Resume()
You'll need to write some logic to check for the status of the job. Once it hits "Transferred" status you can then mark it as complete. This will write the file from a .bin to the file name you listed. Something that helped me was installing the Windows Support Tools (you can get it from a Windows 2003 Cd/DVD in the sup tools folder)and using Bitsadmin.exe to view the status of the job while debugging.
