For the life of me I cannot find the solution to this error. All field lengths match the length of the SQL Server data field. Here is the insert code I am using... the same to the code that is used elsewhere in the program.SQL Server Express 2008 R2 and VB 2010 SP1.

Dim blnPrimaryKeyError As Boolean = False
Dim blnIsError As Boolean = False[code].........
I 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 2 RepliesI need to pass a block of binary data to a web service. The object I'm passing is part of an API, so the Serialize/Deserialize/Byte functions are built-in to the API class. It is not explicitly XML Serializable as far as I can tell.
Unfortunately, whenever I pass the data to my web service, even as an encoded string, the service returns a "(400) Bad Request" error. If I remove the encoded data and replace the variable with a simple string, an appropriate response is returned, ruling out authentication, service errors, etc.
'Convert the byte array into an encoded string'
Dim unicodeEncoder As New UnicodeEncoding()
Dim serializedData As String = unicodeEncoder.GetString(myObject.Bytes).Trim()
Dim webAuth As New myWebService.ServiceSoapClient
MessageBox.Show(webAuth.VerifyFeatureSet(serializedData , "", "", "", ""))
how I can accomplish this? If I need to encode the data a different way, include a snippet for decoding it on the far end.
I've made a Access database of my CD collection I have lots of movies and I copy the picture of the original DVD from www.imdb.com into my database in a OLE field I can see the picture that's connected to the desired record just fine in access but now I'm working with Visual Basic express 2008 and I want to connect this Access database to my project. I can see the data just fine but not de OLE pictures
I changed the properties of that picture into a picturebox in de datasource screen bu I don't see a picture (blank)

View 4 RepliesI 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.

How can i convert hex data to binary data and write it to registry anyone ?
View 5 RepliesI 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?
I 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.
I'm a beginner programmer, but this may not be a beginner program question. I would like to write a program in small basic or visual basic that reads data from a binary file. The data are formatted in hex and look like this:

View 2 RepliesI'm designing a very simple program that will need to save both data and photos to a cd but my code refuses to let me do it. Here is what I have:
FileOpen(1, "E:FileWithData.dat", OpenMode.Binary)
FilePut(1, AString, 10)
I keep getting an incorrect function at FileOpen
I saw some methds which take numerous lines of code but I like to keep my code very simple so I can easily tell what it does.
I want to store data in binary format in VB. Are there any disadvantages to use the functions fileopen, fileput, and fileclose instead of serialization using binaryformatter object. Using these functions seems to be easier and more compact.
View 1 RepliesI 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.
I'm currently working on a program that would take the binary data from my access database and convert it back into jpeg format so I can store the images in a folder. I'm really new to VB so right now I'm pretty much stumped.

Option Explicit On
Public Class Form1
Private cn As ADODB.Connection

I 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
