C# - The Input Stream Is Not A Valid Binary Format / Cannot Use Binary As The Length Is Around 15.000

Feb 3, 2011

I have a problem with deserializing in C#/ASP.NET, which gives the exact error:

The input stream is not a valid binary format. The starting contents (in bytes) are: 41-41-45-41-41-41-44-2F-2F-2F-2F-2F-41-51-41-41-41 ...

What I am trying to do

I have a structure with 3 classes. I have a class A which is a base class, and then class B and C which are derived from A.

I am trying to store random types of B and C in the database using LINQ to SQL, in a column with the type VARCHAR(MAX).

I cannot use BINARY as the length is around 15.000.

My code...

[code]...

So the error happends when the first Deserialize method is run, with the above error.

C# - How To Write Binary Data "as Is" To Registry (ie: I Have Visible Binary Data As String From Regedit Only)

Feb 23, 2011

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!

[Code]...

If I had the following in a string or a bit array, what must I populate the bitarray with so that the registry outputs this [above] when written? or, how can I figure out how to do it? I was hoping there'd be a function that reads my string of binary data and transforms it into the real binary format to submit to the RegSetValueEx function in VB6 or other function in VB.Net or C# (this really is a language agnostic question, and the problem exists in all languages; ie: same process).

SQL Server :: Binary Data Not Writing To Database?

Sep 24, 2010

I have an ASP.NET app that writes binary data to a SQL database. It worked fine using SQL Express, but does not ever write the data using SQL Server 2008 R2. SQL Profiler shows the binary data in the UPDATE query, but nothing happens... no errors, no data saved. Does anyone know what I'm missing? Other data types work fine.

My data type is VarBinary(MAX)...

Outputing A Text File Of 1s And 0s - Convert Binary To Ascii?

Feb 13, 2010

I am outputing a text file of 1s and 0s. I want to shrink the file so I'm going to convert it to ascii. Its going to be used on a clientside web application so I can convert it back to binary with some scripting later on.

So, I want to convert the string of binary to a string of ascii serverside in vb.net. I have spent much time searching the web for a vb.net solution, and, what a mess!! everyone thinks they know how to do it, but none of the solutions have worked so far!!

How To Make NHibernate Serialize A Given Property To A Binary Field

Sep 14, 2010

I have a simple ASP.NET MVC web application that uses NHibernate with FluentNHibernate's auto mapping feature for its data access. I have encountered a scenario in which I would like NHibernate to persist some classes as binary data.

public class User
{
// This field will be persisted
public virtual byte[] PortraitData { get; set; }
// This method will get me what I'm actually interested in
public virtual Image GetPortrait()
{
return SerializationHelper.Deserialize<Image>(PortraitData);
}
}

(I leave the implementation of the SerializationHelper class to the reader's imagination. It doesn't do anything complicated, just serializes and deserializes data into byte arrays and back.)
