View 1 RepliesI'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?
View 4 RepliesI 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'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 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 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

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.
View 9 RepliesOk, so I know I have to change the labeledit to true but that doesn't change the selected node to be able to edit, so how does that work?
Along with renaming I have it set to that a user can add a node. So once the node has ben added how do I let them rename it as it is being added and without being a prompt or inputbox? So lets say I cam clicked on a parent and they click add node, it adds it to parent but I have it so it is default "New" but I want them to edit it as it is added. I think it will be along the same lines as clicking on one and rename but I have to start some place.

View 3 RepliesAlright I know that this question is asked all too often on vbForums but I am running into this problem and none of the posts have been clearly answered, a majority of them just redirect to some deprecated VB6 code that cannot be transferred easily to VB.Net. I was wondering if anyone would be able code to refresh my Local Area Network settings on a windows seven computer.I have code that will set all of the registry values that I need. (I have read on other posts that this is not the best way but then they just link to old non-.Net code that will not fit into my project.) I was wondering what exactly the 'Ok' button when you exit the LAN Settings window does, because this part is what actually refreshes the Ip of the computer to use proxy settings set by the registry values, I was hoping to have my program only be one button, that would do all of this without it opening the LAN Dialogue (requiring further human interaction.)
