My small box sends the same byte continuously to the PC across a bluetooth connection.

After successfully receiving about four thousand bytes (give or take a few hundred) no more bytes are seen. I am quite confident that the bytes (a whole lot more than four thousand) continue to be sent well after the stream disappears from the rest of the system.

I am highly suspicious that Windows is somehow, for some reason, not accurately giving these bytes to my app.

My suspicion has been heightened because my external transmitting box continued after I stopped the app. I restarted the app, and I got 941 "left over" bytes, from where, I don't really know (but my external byte generator had been silent for several minutes, so it was no longer sending data).

We then started the small box generating continual data again, and saw the same behavior: 4435 bytes were seen, despite a two minute flood of bytes at 921600 bps.

Here is the receive thread

void RecieveThread()
 {
     int n;

     while (continueRecieving)
     {
         n = connectorPort.BytesToRead;

         byte[] bits = new byte[n];

         if (n > 0)
         {
             connectorPort.Read(bits, 0, n);
         }

         Write(bits);
     }
 }

Just in case anyone feels it's important, here is the Write(bits) routine

public void Write(byte[] b)
{
    if (writting)
    {
        for (int i = 0; i < b.Length; i++)
        {
            storage[sPlace++] = b[i];

            pass += b[i].ToString("X2") + " ";

            if (sPlace % numericUpDown1.Value == 0)
            {
                pass += "\r\n";
            }
        }
    }
}

Has anyone previously experienced disappearing bluetooth bytes on a Win7 machine with a C# app ?

How to use database view with Fluent nhibernate?
How can i recall views that are created manually in database with nhibernate technology or is there any option in Fluent nhibernate that create views directly?

Hi,

I am using MSI to install my c# winform application. I am using custom action at the start of the installer. This is my latest version where I have added custom action. When I install latest version (fresh installation) then it works properly. But when I install latest version on previous version my custom action related registry key(e.g. ModeSelection Key) is not creating in the registry but some basic and common key(Filepath,language etc) are created successfully.

What is the reason behind this? I wanted to create that registry key depeding upon the custom action selection.

Thanks
sjs

I am trying to draw a TextBox in my DUI framework. At last, I find a way to create a windowless RichTextBox with a custom ITextHost interface.I've got a C++ implementation. But when I try to implement it from C#, I got a lot of exceptions.

C++ Code:

I recived ExecutionEngineException and AccessViolationException again and again. Is there any problem with it?
Thanks in advance!

Implementing C++ interfaces in C# is a pain. You could create a wrapper with managed C++ and then derive your C# class from the managed C++ class.

C# Receive from TCP send to COM2

I have a Software Program from a MICROS Server that can send via TCP or Serial Port. I have another application on another server that sends and receives data from the MICROS Server through a physical null modem cable on Serial port COM2. I am virtualizing the MICROS Server and that does away with the Serial Port communication. I can't change the Server that receives the data from a Serial Port. So, does anyone have a solution to send from the MICROS Server through TCP to the second server and be able to pass that down to COM2 and be able to have COM2 respond back through the TCP port back to the MICROS Server without having a physical cable? Any code support would be greatly appreciated.

Why are your attempting to create your API at the TCP level rather than just create a Send/Receive API and let the API internals deal with the communication?

I might have not explained it correctly. I have been asked to Virtualize a Microsoft Server which runs an application Server Software called MICROS. MICROS is used as the back end for POS Systems. When MICROS gets a transaction, it can send that transaction out through TCP or Serial Port. There is another Server that is connected to the MICROS Server via null modem cable. Since we are virtualizing the MICROS Server on a Windows 2008 R2 Server, we can not get the Serial Port to pass through from the Virtual Host because Microsoft no longer supports passing through Serial Ports from the Virtual Host to the Virtual Session. I am looking to create a C# Application to take the place of communicating on both sides because the null modem cable can not be used. The Server that receives data and sends data back to the MICROS Server is an old outdated piece of software that I can't change right now because there is no newer version. It is a DOS Application. So, I am looking for a way to pass Serial to Serial through Named Pipes, Serial to TCP, or any other method. If the receiving Server was able to send and receive via TCP then this wouldn't be an issue. My client is pushing me to make it happen.

Thanks! Smile | :)

Unless I'm mistaken you are looking for this:

I used the free variant and it works perfectly fine. You can create any number of serial ports and connect them virtually on the same machine or remotely over tcp/ip. You can also create gateways and bridges. Very neat.

I guess you have buy it, the server variant is not free.

Hey

I get results from an searchengine that i need to split into pieces. The structure looks like this:

[ // begining of file
   { // struct 1
       "name1":"value1",
       "name2":"value2",
       "name3":"value3",
       "name4":"value4",
       "name5":"value5",
       "name6":"value6",
       "name7":"value7",
       "name8":"value8",
   },
   { // struct 2
       "name1":"value1",
       "name2":"value2",
       "name3":"value3",
       "name4":"value4",
       "name5":"value5",
       "name6":"value6",
       "name7":"value7",
       "name8":"value8",
   },
] // end of file

In plain text it looks. Like this:

[{"name1":"value1","name2":"value2","name3":"value3","name4":"value4","name5":"value5","name6":"value6","name7":"value7","name8":"value8"},
 {"name1":"value1","name2":"value2","name3":"value3","name4":"value4","name5":"value5","name6":"value6","name7":"value7","name8":"value8"}]

I don't understand how to split this in parts. What I done is this:

\[(?<text_between_brackets>.*?)\]

But that only gives me the text between [ ] so how do i add commands for splitting { } and : ?
I want each structure with values, I don't care for the names.

Thanks
