We are developing an Android Application (Java) that reads an image, encode the bytes in base64 to send them over HTTP (via GET) to a WebService written in VB.NET.On .NET side, they are using this :
Dim Pix As Image
Pix = Image.FromFile("C:UsersPublicPicturesSample PicturesTree.jpg")
Dim ms As New MemoryStream[code]....
How can I pass the correct string to them to correctly decode the image from Java encoding (unsigned) to .NET decoding (signed)?
i'm using the following algorithm to encrypt and decrypt a string in VB.NET and wanted to do that same method in Android also.
Encryption:
Private Function decryptStr(ByVal key As String, ByVal enc As String) As String Try DES.Key = Hash.ComputeHash(System.Text.ASCIIEncoding.ASCII.GetBytes(key))
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?
Is there a Java equivalent - specifically on Android - for VB.NET's Static keyword? For those not familiar with VB.NET, take the following code snippet...
Sub MyFunc() Static myvar As Integer = 0 myvar += 1
I have searched everywhere to find an answer for this question: I have a TCP client on my android application that sends an message to the server which is written in Visual Basic .NET Framework 4. Now i want to send an message from my server to the phone over 3g, it works on wifi and 3g..
I'm using WinPcap to capture incoming data. Basically I'm dealing with a continuous stream of incoming data, either as byte array or as memorystream (pieces up to 64kb).
I need to check this data to see if there's a certain url and then extract it.
The url I need to find looks like this:http://201.122.38.5/data/today/798572987-589571?139805890582 The length of the 'code' after "/today/" is always the same. The IP address changes. What's the best/fastest/most efficient way to continuously check these byte arrays or memorystreams and extract the urls without hogging the CPU too much?
I've tried rewriting this code several times, it spits out the bytes correctly, but then when trying to read the array created from the memory stream, it's empty, what am I doing wrong?
Dim bytes() As Byte = System.Text.Encoding.ASCII.GetBytes("test this shit") Dim bytesString As String = "" Dim i As Integer = 0 i = 0 Dim byteStream As New System.IO.MemoryStream
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?
ok i have image that i bind info in it and i want to read the info now from file (FileStream) its workbut i want to do it not from file so i need to use MemoryStreamhere the example that work and how i do it now how i make it work with MemoryStream (with byte = My.Resources or PictureBox1.image)
Using FS As New IO.FileStream(image, IO.FileMode.Open) FS.Seek(0, IO.SeekOrigin.End) While Not FS.ReadByte = Asc("|")
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 am a Java developer. I have the task of converting a VB class to Java.Can some VB developer comment the following VB code so that I can write its Java equivalent?
Public Class RmaValidationCode ' Values for test type Public Const SOFTWARE_TEST_TYPE = 0
i need to convert a Java tool into a VB (2005) application. Most things are fairly straight forward, but i have on a few lines my problem the appropriate VB function to find.
I wrote a Java class that parses a bpel text file and then returns a count of the number of occurences of certain words. I wanted to convert it to VB2008 Forms application, so that its results are displayed in a TextBox and not on the console. The problem is that VB2008 lacks Scanner and StringTokenizer classes, which are in my current Java class. Am not sure how to get the same functionality (or better) in VB2008. Can someone out there help to convert this class.
I am trying to convert a public adaptation of the Whirlpool hash from Java to VB.NET, I am getting errors that do not make sense to me and thusly I don't know how to fix them.
I am trying to learn OOD/OOP and read on the net that I am not supposed convert SQL tables into classes. But I cannot find an explanation why not to do it or which tables to skip. So I made an web application based on the below diagram. It works perfectly well. But I do not use OO. which table should not be mapped into a class and why not. do not use LINQ or NHibernate, etc as I do not understand them. I just need to understand the OOD.
How to convert byte array to ASCII in VB.NET System.Text.Encoding.ASCII.Getstring(y) it gives the data like 52414D41 . but i need "RAMA" instead of 52414D41.
My application is reading in data from the serial port. The packet format uses 1 byte to tell the data length. The problem is as I am reading each byte in as a char when I try to get the value of the received character (using Asc(cRxd)) it only works up to values of 127, any bytes received that are over 127 are received as 63. I noticed that this was the default parity replace value, but I have parity.none set and I also changed the parity replace value. The received byte is always 63. I have tried reading the data using .ReadByte but this gives the same result - only works on values below 128.
How to convert byte to bitmap Dim ScreenshotBytes As Byte() = MySQLExecuteReader("SELECT Screenshot FROM Connections WHERE Connection='EC8C35F2'", "Screenshot") Dim ScreenshotMemoryStream As System.IO.MemoryStream = New System.IO.MemoryStream(ScreenshotBytes) [Code] .....
But I don't know how to get the bytes from the mysql server: Public Function MySQLExecuteReader(ByRef StrCmdText As String, ByRef StrColumn As String) 'On Error Resume Next Dim MySQLComm As New MySqlCommand(StrCmdText, Connection) [Code] .....
I want to return the byte from the column: "Screenshot" which is an image (MEDIUMBLOB) so I can use it as a background for a picturebox.
Ok, I am tasked with changing certain text labels that exist within 1000's of CAD files. The only way to change the text labels, as of now, is to open each CAD file in a CAD editor, change the labels by hand, and save it as a new file name, and that will take forever.So, I want to make this job easier and to do that I need to write a program to do it automatically (not a Macro). So far, I have made an app that loads the CAD file's bytes, finds the position of the label's text bytes, and replaces the text bytes with my own bytes, and saves the file under a new name.The problem is, I don't know the format/encoding/whatever they used to write the string to bytes..... The good thing is, I have unlimited examples to learn from because I can use the CAD program to change the text and then see the results in Hex. I want MY program to mimic the results.Here is some hex examples;
13 BE FD F9 00 = wood 0F 1E 1E 80 = cat 0F 26 FC E0 = dog
