C# - Write Binary Data "as Is" To Registry (visible Binary Data As String From Regedit Only)
Feb 23, 2011I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out...
I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically. here is the culprit!

View 14 RepliesEncrypting Data Using A Binary Formatter
Aug 20, 2009I am currently using a binary formatter to serialize/deserialize some data objects. Some of the properties in the classes are Strings. When the data is written you can open the file with a text editor and can see the raw String data. Is there any way to encrypt the Strings or the entire object before it is serialized? I have looked at this thread here [URL] but the code is in C# and the free converters I tried for some reason did not like the code. This is the code I am using currently.

View 5 RepliesOpen PDF File From Binary Data?
May 3, 2011I have a VB.NET dll which pulls out binary data from and opens it as a pdf. It works fine if I create a file on the user's machine and then open that. What I want to do, however, is just open it in Adobe without creating the file on their machine first (there's customer data in the file and we don't want copies of it sitting around unecessarily).
It's possible in ASP.NET to just stream the data to a browser and open it in that without creating the file, but I can't find a similar methodology for doing that straight to Adobe. Does anyone know if this is even possible or do I have to create the file in order to have it open?
Read Binary Data From Registry?
Jan 10, 2010I have a serious problem reading that stuff, it seems I can't get it right.The registry key I want to retrieve looks like this:
And this is the code i used:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim readValue = My.Computer.Registry.GetValue _[code].....
The problems is that it returns something like: "V???????=dQ???!u?1?" What the ____ is that anyway? So in reality it should be like "c3gm322dvf" or something like that.

Store Data In Binary Format In VB?

View 1 RepliesCommunications :: Parsing Data From Binary Socket
Sep 7, 2008I am using VB.NET and I am designing a generic network architecture in which data can be transmitted in various ways. I am wanting to strip down things as much as possible, and I do not want to transmit in plain text. My question today is regarding ideas and example code (if applicable) as far as parsing binary data that is sent over the wire in VB.NET.I want each packet to have a very generic architecture such as <packet type> <address> <payload> or whatnot. I understand that I can use certain bytes as delimiters for these packet fields. I don't necessarily want to serialize everything being that for security reasons, the same library has to be used to deserialize the data.
a) Put my protocol into binary data where each field is delimited using a certain byte
b) Parse that data from binary at the other end.
Once again, I don't want to use plaintext since this can cause a bunch of overhead in comparison.

Convert Bitmap To Icon Using Binary Data?
Feb 21, 2011I would like to convert an Bitmap image to an icon in VB.NET but I have to use the binary data of each to somehow accomplish that. Doing research on Bitmap I found how the files are structured. I know that bitmaps have the Bitmap Filer header, Bitmap infoheader, and the colorallet. Each of these contain a certain amount of bytes, and I a have to get these from the bitmap file. The icon header and info header are similar to the bitmap. I know that there are libraries in VB.NET that do that easily, butthis is for a project for school and I am not supposed to use that. I just want to ask how

Binary -store/retrieve Bit Data From File Using BinaryWriter?
Apr 11, 2012I need to store/retrieve a bit from a data table of 3.268.760 bits long.
Using w As New BinaryWriter(File.Open("test.bin", FileMode.Create))
for x = 1 to 3268760
For i = 1 To 3268760[code]....
the w.write(?) stores a boolean value meaning 0/1 for false/true values, but Vb.net seems to use an whole byte to store this data which is too expensive for my table (3.268.760^2).Is there a pratical way to store/retrive single bits from a file using vb.net? (meaning as little as possible conversion to other types).
Cannot Set System Data Linq Binary Field Using Reflection
Oct 24, 2011I cannot get the following to work for me: its the section that sets the default for system.data.linq.binary. The database I work with doesn't allow nulls in any field. So I generally run my buffer through this routine to populate defaults and then set the real values independently, (this works when I miss a field). I can set the Linq table field = fakeBinary and it works like a charm. Thus, I don't understand why using reflection can't pull of the same thing.
Ex: Me.CM20500WindowBuffer.Reconcile_Messages = New Byte() {0} works.
Try
Dim fakeBinary As System.Byte() = {0}
For Each fld In nObj.GetType().GetProperties
Select Case fld.PropertyType
Case GetType(Byte)
[Code] .....
