Hi,

when you enter some festivals, you get the program of this festival on your cellphone when your Bluetooth is on.

Now I want to write a similar application that broadcasts a text message to all the devices in the surroundings of my laptop. Has anyone here some experience with Bluetooth and sending text message over Bluetooth?

I've found this library of 32feet, but I don't know if it is any good...

let met know!

Since nobody seems to understand my question, i will specify it.

Does anyone here has any experience with Bluetooth and mobile phones?
I would like some advice about the libraries I could use or maybe that I should write the entire communication myself.

let me know

Hello I am making http calls from my C# desktop application.
I want to use Gzip compression while posting data and also deserialize the server response that is in GZip compression. Any help for that.

Try using the GZipStream class.

Do not forget to modify the content type of the http header in order to correctly handle it on the server side or client side.

Getting UNMANAGED stack trace in C#

Is it possible to get UNMANAGED stack trace in c#. Here is what I am trying to do:

I have a COM written in c#. I have VB6/C++ code calling this COM component. In the COM component, I want to be able to find out who called the COM function(s).

I have tried using the System.Diagnostics.StackTrace class, but that seems to only return MANAGED stack traces.

For Example:

COM Interface/Implementation
<pre>
[Guid(###)]
[InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface ISkel
{
[DispId(1)]
void DoSomething(int id);
}

[Guid(###)]
[ClassInterface(ClassInterfaceType.None)]
public class Skel : ISkel
{
public void DoSomething(int id)
{
...
}
}
</pre>

VB (VBProject Name = VBProject1)
<pre>

Private Sub Command1_Click()
dim s as new Skel
s.DoSomething(1)
End Sub
</pre>

From the C# code, I want to get a value indication that the calling project (VBProject1) and the method (Command1_Click())

Any ideas/suggestions?

Thanks in advance.

AFAICT, the StackTrace will only work with managed calls. I can't find any method of getting the unmanaged stack trace from managed code.

You cannot view unmanaged code in the stack trace - you could use the disassembly window, however.

Excel Addin MiniDump

I have created a dump of an excel addin and I'm having trouble loading it. When simply opening it with Visual Studio 2008 it gets to run after it loads the symbols but the "go to source code" button is grayed out.

Second time I run it it throws the no source code error however I have specified the source code directory.

I'm afraid that being an Excel addon I also need to have the excel sources?

Noone is going to be able to help you becuase you haven't asked a question nor specified anything about the add-in you're writing, the problem you're having, the code you've written, ..., no nothing. So, how is annyone supposed to help you solve your problem?

ADO.NET cross-base transactions

I made a simple transaction using ADO.NET:

SqlTransaction tn;<br />
SqlConnection cn = new SqlConnection(/*connection string to 'Database1'*/);<br />
<br />
            try<br />
            {<br />
                if (cn.State != ConnectionState.Open)<br />
                {<br />
                    cn.Open();<br />
                }<br />
            }<br />
            catch (SqlException ex)<br />
            {<br />
                Debug.Assert(false, ex.ToString());<br />
            }<br />
<br />
            tn = cn.BeginTransaction();<br />
            SqlCommand cmd2 = ...

This works nicely. However I would like to make some update statement in other database - 'Database2'. Is it possible to do that inside one ADO.NET transaction? If so, how?

Thank you for help in advance.

Look, retard... You posted the same message twice. I wanted you to delete your first message before someone replied to it because once it's replied to, it can't be deleted. Now, someone's replied to it and it has become the "rubbish" that you are so clearly averse to.

You can include your two queries into a TransactionScope.
The framework will automatically create a distribute transaction between the two databases.

Keep in mind that your infrastructure must be configured to allow so (see Configuring MS DTC).
