I have an Informix stored procedure which takes an int and a "smallint" as parameters. I'm trying to call this SP from a .net4 Visual Basic program.As far as I know, "smallint" is a byte. Unfortunately, when loading up the IfxCommand.Parameters collection with an Integer and a Byte, I get an ArgumentException thrown of {"The parameter data type of Byte is invalid."} with the following stack trace:
am trying to pass a structure that contains 2D arrays as Byte from VB.net to a C++ dll. The dll returns the structure with the 1D arrays filled. I am using UnmanagedType.ByValArray to pass the arrays from VB.net to C++.
I create my algorthm and its finished but there is a problem, it encrypte all text and all text in a file but after decryption when i open my file (a video file)the player show all information about file(duration,size and ect) currectly but it dont play that my program encrypt and decrypt byte by byte and place a asci code in bytes(0 to 255)
I just converted the following code from c# to vb.net. It is functional and works correctly with my company's firmware/devices. My next challenge. Previous serialport code used much more readable structs which where then converted (after building a packet) into byte() automatically as part of the serialport encoding. (this is my understanding)How could I
1. morph byte arrays 'ToSocket' and 'ToMTP' below into structs and
2. convert into byte array for Socket.BeginSend(byte(),.....) to stream out to remote devices?
Is it possible in VB to truncate a larger data type ( an int with a value greater than 255) to a smaller one, say a Byte (which only goes up to 255) in a way such that the 8LSBs of the integer are copied to the newly created byte. I have tried this using CType with the following code, however it does not work.
Dim TestByte As Byte = CType(Test, Byte) Where the variable "Test" is an integer with a value of 419. This code always results in the Overflow exception.
I have 2 byte arrays. I want to merge these two byte array into 1 byte array.Usually, I just create a new byte array with length = byte array #1 + byte array #2. Then copy byte array #1 and #2 to the new byte array.do I have more efficient way to merge 2 byte array using VB.NET and .Net 4?
I would like to create a function so that I can pass a string and it will return me the binary value, I will use this later in other parts of the script but I am getting an error that I don't understand.
Private Function ConvertToMD5(ByVal OldPassword As String) As Byte Dim NewPassword As String = "" 'The string we wish to encrypt
[code]....
On the "Return hashedDataBytes I get "Value of type '1-dimensional array of Byte' cannot be converted to 'Byte'"
I have a byte array that I convert into a string like so Dim byt As Byte() = New Byte(255) {} s = New String(Encoding.ASCII.GetChars(byte))My question is when I look at the string in a debuger its clearly a normal string but when I compare it to what I know its supposed to be it doesnt equal. So i did a quick check and for some reason its return a string thats the length of 256 characters. So i did a s.trim and it still is 256 characters long.
I would like to know how to convert a unisgned byte to signed byte
Atm I got this
a Function readSignedByte() As SByte '-128/127 Dim b As SByte
[Code]....
it doesn't work one that well works for numbers positive over 127 if lets say ReadByte() has 128 it would give overflow error which I don't want it to give I would like it to overflow the number to negivate value aka its signed value.
given my code below, I'm trying to figure out how to create an array of 1 byte containing 7 bits. So the byte in the array would contain 0111111 to correspond to mData_Out's boolean values. How would I change the following code? [Code]
I am trying to write some code to get a kinect for windows sample running, which is originally written in C#. I get stuck with translating the following C# code to VB.NET:
byte intensity = (byte)(~(realDepth >> 4));
What is the VB.NET equivalent for the code above? how to translate the "~" code sign.
Table2 should be updates from table based on the results... If all results is PASS then the table2 should be updated as pass... if any result is FAIL then the entire case_no should be updates a s fail..
This code was working consistently, but now...This code works on the first pass.Then second pass it just hangs on Code:Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() for about 2 minutesThen the code will fork for another pass, then fail.....
Just started VB programming this week and have found a wealth of information about what I'm trying to do. Problem is, some of it is more complete than others.Here's what I'm trying to do:In Form1 (my main form), I want to instantiate a class that contains a couple of properties (speed setpoint and position setpoint). When I click a button, I want to pass this data to Form2 and populate two textboxes on Form2 with the properties of this object. I want to manipulate the property values on Form2 and click an OK button which closes the dialog and returns the manipulated data, updating the property values of the object. Here's the algorithm I'm following:1) On Form1, instantiate the class2) On Form1's "Pass Data" button click event handler, instantiate a Form2 object and invoke the ShowDialog method, passing the object as a parameter.
3) On Form2, overload the ShowDialog method to accept the object as a parameter and modify the method so that it returns the manipulated class data.4) On Form2, in the ShowDialog method, populate the textboxes with the class data that was passed in.Here's where I get stuck. If I press the OK button on Form2 (DialogResult.OK), it returns me to Form1, but what hook do I have in Form1 to receive the manipulated class data that the ShowDialog method is returning?Here's an example of what I'm thinking about:
Code: Public Class Form1 Dim clsController1 As New MotionController
[code].....
I'm sure it's probably a very elementary question, but every explanation I've found seems to be incomplete.
if a byte value can go up to 255 and two bytes are used to determine the length of packet payload data, how would I convert the two bytes to create one integer value?
State.buffer[13] = 5 and State.buffer[14] = 67 Dim PacketLengthHigh As Integer = state.buffer(13) Dim PacketLengthLow As Integer = state.buffer(14)
I don't understand that error that occurs on the second line of code below. I'm trying to skip over the first 18 bytes of a byte array that I'm accessing from a c# dll into a local vb.net byte array
I am trying to Convert a data field stored as IMAGE ( SQL Server 2000) using Java to a byte array using VB.NET Java uses signed numbers for a Byte array where as VB dosent. Can somone point me to how I can covert java byte array to VB byte array?
i have a table in sql server with some fields set as Byte() (System.Byte[]) when i import them in my application to be used with linq they are converted in Binary (System.Data.Linq.Binary)why is that?is there a way to prevent this wrong translaton???if i update the database how can i update the classes that has been craeted in visual studio2008?
I am trying to get a count of all the times a byte sequences occurs in another byte sequences. It cannot however re-use a bytes if it already counted them. For example given the string let's assume the byte sequence was k.k it would then find only 3 occurrences rather than 5 because they would be broke down like: [k.k].[k.k].[k.k]. and not like [k.[k].[k].[k].[k].k] where they over lap and essentially just shift 2 to the right.
Ideally the idea is to get an idea how a compression dictionary or run time encoding might look. so the goal would be to get down to just 2 parts, as (k.k.k.) is the biggest and best symbol you can have.
Value type "Byte" cannot be converted into "1-dimensional array of byte"Does anyone know what is missing?
Option Strict On Private Function MySQLDataReader_GetByte(ByVal Connection As MySqlConnection, ByVal CommandText As String, ByVal Column As String) As Byte()
I am looking for some input. I am helping with a web application that is fairly large. We have some logic factored out into classes, not a true business logic layer (yet ). The classes are setup to pull values directly from the QueryString or Session variables and I'm not sure that that mehtod is proper or even a
The reason I would like some input is, there may be a chance to rewrite or at least refactor the code.
