I've been up for nearly 24 hours now. Trying to program an application for a game I have been playing.I've run in to a problem, I'm not sure how to solve.I have basic knowledge when it comes to VB (college class) so bare with me.[code]My only Idea would be loops to figure out where each of the edited numbers are in the array, But I was looking for something simple.Also, would it be easier to work with the bytes rather than edit them in string form?
I have a StringArray that is filled with line of text and I need to take each array of strings and convert them to byte. How
Dim splitText() As String = TextRead.Split(Chr(13)) Dim byteArray() as string = Byte.Parse(splitText(0))
once I can get one element of the string array to convert to Byte I will put a loop around it for each position in the string array but it says the string format is not correct for the byte.parser.
I am trying to use socket to transfer byte to client. I define Byte(1024) because I am not sure how many character is the server sending! I don't know how many index of this array has been occupied!?
I'm stuck at a little Problem. Well I got an Image in a Picturebox and need it to convert it in a Bytearray to store in an Imagecolumn in a Database. I do know how to convert a FILE to a bytearray, but I'm stuck at this. would be appriciatet. This is what I got so far, but like I said, it didn't work properly.
When declaring a byte array, what is the difference between the following? Is there one, or are these just two different ways of going about the same thing?
I wish to convert image 24bit RGB pictures to an RGB (or BGR) array of byte, and convert back array to RBG. I need speed, so I was suggested to use memorystreams, but have no idea where to start.
have this code: Friend Shared Function RGBArrayToImage(ByRef RGBArray() As Byte, _ ByRef Rows As Integer, _
I got a form and a checkbox with default names. In the form1 load event, I need to check the binary data of a registry key. If data is 00 00 00 00 the checkbox will display a check mark If data is 1b 00 00 00 the checkbox will shows nothing
Here is my code Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim b() As Byte = {0, 0, 0, 0} Dim a() As Byte = My.Computer.Registry.GetValue("HKEY_CURRENT_USERSoftware", "Test",String.Empty) If a Is b Then CheckBox1.Checked = True End If
I gotta change my HexString to ByteArray. so I have this getHello String.
CODE:
And I have the function I found out here.
PHP
CODE:
Alright so the code doesn't work. "Index was out of outbounds array". Is there someone whome can make a right function that will change the HexString to ByteArray?
I am transmitting data over an IP socket and receiving the data via a second program I have written. The server was in VB6 and am now creating a new one in vb.net to run as a service. The major issue I am having is related to the encoding features.
Issue 1 to be able to correctly encode a bytearray so that when it is received by a VB6 program via winsock that the data will be in the proper ANSI format for the pc to read it correctly. So far this works on some files and not on others depending on the content of the file.
Issue 2 to be able to correctly encode a bytearray, send it to a vb.net host program and correctly [decode?] write it to disk.
To make things a little more complicated I must also be able to do this where the client resides on a Windows Mobile, Windows CE, or Windows PC. I have been running some tests and have gotten mixed results.
In my project I am using a camera to capture images. The images will be stored in a byte array. Now I want to display my images in byte array to picture box on my form. I am pasting the code bit below.
HTML Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (ByRef Destination As Byte, ByRef Source As Byte, ByVal Length As Integer) Delegate Sub MyFrameHookerDelegate(ByVal FrameType As Integer, ByVal row As Integer, ByVal Column As Integer, ByRef lpImageAttribute As TIMAGEATTACHDATA, ByRef Buffer As Byte) Public ImageBuf() As Byte [Code] ....
I want to display the image from ImageBuf() to a picture box on my form.
I want to send a image to server side using HTTPService,I am using ASP.NET for server side coding. I don't know how to write server side code to receive the image sent as a byteArray, and I am also not sure if my client side code is correct or not。is there any IT PRO..[code]I could not get the image in my disk,I think the flex side should have not problem, but the VB code side should be something wrong.
i am converting a string to double?i would like to know in advanced whether it would case an error to convert a string to a double. for example if i try to convert "hello" to a double, it would give me an error. is there a way for me to know ahead of time whether converting something will cause an error?
I have made calculator in visual basic that can calculate the costs of products. You first select the type of product. Then you insert the dimensions. After that it calculates de costs. The type op products are stored in a Access database. In this database is stored a formula as a string. The problem is that i can't caculate the selected string with the formula and the given dimensions.
I am trying to convert a string of binary into hex. I have tried several ways and none have worked. This is my latest try. The code runs but doesn't appear to do anything.
I am using the .NET Framework 2.0, and I am trying to code a client bot for a game called Minecraft, Originally written in Java, there have been quite a few people who have made custom multi-player servers for this game, Primarily in C#, or in a language that i've never heard of, such as Pascal.I'm looking right now at sending this:
Packet ID: 0x00 (0) As Byte Protocol Version: 0x07(7) As byte Username: "umby25" As String
[code].....
"Byte cannot be converted to 1-Dimensional array of byte"
I don't understand why this whole thing would work in all of the other programming languages, but not Visual basic.I have tried converting the string using the same method that one of the open source C# servers used, and it failed, telling me that the dictionary does not contain that or something.
I am having trouble converting a string value to a text box name.The text boxes are created at runtime and I need to get the text value out so I can store them. I keep getting the error [code]
I was trying to figure out how to convert a string (that the user would input to the program via a textbox) into actual code for the program to compile. For example, if the user was to enter: (5*100)+(20-3). How could you take that inputted string, and have the program solve it and return the value?
I have a combobox that pulls a list of values from a database. When a new entry is entered I want an entry in the combobox to read "New record". However, from what I have seen I can only insert and object, such as a DataRow, into the combobox. Is there anyway I can convert a string to to a DataRow, or some other object and insert it in to the combobox? I know there is I am just rusty on my vb.
I'm using AxVLC to try to play a video from my.resources and I can't seem to convert the binary to a string for it to work...This is what I have so far - produces no errors, or results (nothing happens).
I'm trying to convert a chosen color into hex base 6 to save to a config file for later use, and that part works, but when converting back to integer to use for a color, it gives me an error about incorrect base.
Dim hex_color = System.Drawing.ColorTranslator.ToOle(ColorDialog1.Color).ToString("X6") Dim color_int As Integer = Convert.ToInt32(hex_color, 6) Panel1.BackColor = System.Drawing.ColorTranslator.FromOle(color_int)
I was trying to convert from Double to String and everything working fine. But when I tried some bigger number with fractions in it. I got the number but rounded. I tried something like that:
Dim dd As Double = 1235212435.3453636 Dim str As String = dd MsgBox(str) But what I got is 1235212435.34536 instead of 1235212435.3453636
I've got a richtextbox but want to check the keypresses before they come in the textbox. So I thought of using the KeyPress event from the form, checking that key and than writing it to the richtextbox with the Text property.But the KeyChar is a char while the Text property expects a string, and when I convert the KeyChar to a string(ToString) it gives a error.Does anyone know how to fix this or has anyone another idea for checking the presses before writing them?
