Why Does A Negative SByte Number Have 16 Bits
Jul 11, 2011I asked a question earlier about comparing numbers using the "And" comparison operator in If Statements and now I have been toying around with getting my head wrapped around bitwise operators. So I have written a very basic code that will allow me to see the conversion of any decimal number in binary format.[code]Notice here that I am using SByte as the paramerter - which should only contain 8 bits right? However, the message box that appears has 16 bits assigned to negative numbers.
View 1 RepliesCalculate The Lower 7 Bits And 7-13 Bits Of Two Hex Numbers?
Apr 8, 2011I'm trying to figure out how to calculate the lower 7 bits and 7-13 bits of two hex numbers.
Here is some example c code, just need this in vb.net:
serialBytes[2] = 0x64 & 0x7F; // Second byte holds the lower 7 bits of target.
serialBytes[3] = (0x64 >> 7) & 0x7F; // Third data byte holds the bits 7-13 of target
The 0x7F is a constant so the only number that changes based off input is the 0x64.

Compiling In 64 Bits With A 32 Bit Dll?
Nov 4, 2010I have a 3rd party dll, and I can't have it referenced while compiling for 64 bit. Is there a way around this? I'm guessing it is because the dll is a 32 bit one, but I'm not sure about that.
View 7 Replies.net :: Storing 4 Bits From A Byte?
Aug 19, 2010What is the best way to store 4 bits from a byte in VB.Net? Where best means:Most straightforward method of storage from a Byte type.The easiest to work with while performing bitwise operations.Straightforward conversion of the bits to other types.Storing them in a BitArray via it's constructor reverses the order of the bits. This means that attempting to get the value of the first bit will require looking for that value in the last entry in the BitArray.
View 3 RepliesConversion To 64 Bits - PowerPacks?
Jul 10, 2010I am moving Visual Basic 2010 Express from a 32 bits Windosw 7 machine to a 64 bits Windows 7 machine. My project contains a PowerPacks line. I have installed the PowerPacks (VisualBasicPowerPacks3Setup.exe) on the 64 bits system, and see them in the toolbox. When I try to open the project on the 64 bits machine. however, I get error messages:The designer cannor process the code at line 56:
Me. ShapeContainer1 = New Microsoft.VisualBasic.PowerPacks.ShapeContainer
The referenced component 'Microsoft.VisualBasic.PowerPacks.Vs' could not be found
I then thought I would just remove the (purely cosmetic) line on the 32 bits machine, but cannot discover how to do this (I would have though: rihgt click, and then delete, but this doesn't exist)

C# - .NET Apps. Bits And Bytes - App Use As Little Memory As Possible ?

Deployment :: Incorporating Bits Of The Framework
Apr 14, 2009I have made a very small (only one form and no database operations) but nifty application and I want many people to be able to use it. My question is: As I only need a very small part of the dotnet framework, is there a way to let the compiler (or so) grab only the parts it needs for the .exe/.msi file, so that users don't have to install the entire 3.5 framework just to run my tiny little app?

View 1 RepliesPosting Small Bits Of Data
Feb 23, 2010Is there another way to easily make a POST request in .NET other than the WebRequest class? I have a very, VERY small piece of data I need to post: password=theword but WebRequest randomly, and I mean randomly, drops the data when posting to my server. I've tested it by using a chunk of code from my server that dumps the request to a console, and I can that the client is sometimes sending and sometimes not sending the POST data.The code that I'm using that uses WebRequest works in another project, when talking to IIS. The server being talked to (a minimal web server in another system) responds properly every time I POST data to it through Firefox. I've got a function in the same project that fires off a GET request, and that works. It just seems like my POST function isn't completing the transaction...something I've noticed in the past when asking WebRequest to handle small strings.[code]
View 2 RepliesSafe To Assume An Integer Will Always Be 32 Bits?
Jul 1, 2011Is 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?
Sendmessage Lvi_getitemtext Not Working On 64-BITS?
Apr 24, 2007I am trying to get the position and text of all DeskTop icons, by sending a SendMessage to the desktop's listview, using LVI_GETITEMTEXT. Works oke on 32 bits, but on 64-bits I always get an empty string back. I also tried to do this using LVI_GET_ITEM< but the same result. No errors, but also no text string. (I do get the x,y position of the icon). What is wrong here?

Change Permissions On A Registry Key And Other Bits From Within Program?
Apr 28, 2012I am trying to write an app to automate several things that I have to do on a new computer once I have deployed an image, hoping someone could give me some pointers for them:-
1) changing computer description - wmi perhaps?
2) changing computer name - again wmi perhaps?
3) changing permissions on an existing registry key to full control
4) changing the "time to display list of operating systems" when booting from 30 secs to 3
5) turn off simple file sharing
6) and setting current user account so that password doesn't expire - at moment I do it from cmd prompt and do "wmic useraccount where "name='name'" set passwordexpires = false
7) change power plan settings so put the computer to sleep is "never" on both battery and mains

Getting And Setting Single Bits In A Byte-array Using .net?
Jul 5, 2011I 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.

Reading Serial Port On Win7 64-bits?
Oct 26, 2011I have a strange problem. We are upgrading a software that works perfectly in a 32-bits environment.Software have to connect to a serial port (or a virtual serial port) and read data and do wathever it has to do with it. Program uses the IO.Ports.SerialPort object.
Now, under Win7 64-bits, is works well when using "real" serial devices, with a DB-9 connector. But using USB device, with a virtual serial port (provided by the manufacturer), it doesn't work at all. I receive nothing on the DataReceive event. But it works fine on a Win7 32-bits.
Strangely, it also works on the 64-bits PC using a program like realTerm. When connected to the virtual serial port, data are received and it's fine. But from our software, it don't. I don't get anything from the serial port.
