Does anyone know how to send an object through TCP Socket?
Or how can I convert an object to a byte array in .NET Compact Framework?
Thanks a lot!!!

Try .Net Remoting (look it up on msdn and there are lots of books). The object must be serilizable first so don't try to move a datatable or a hashtable.

But if I am using .NET Compact Framework, how can I do so? It is because there is no .NET remoting in .NET Compact Framework. Thanks a lot for your reply

You can use binary serialization to write the object out as a binary stream and reconstruct it at the other end.

private void Serialize(NetworkStream stream, object obj)
{
   BinaryFormatter formatter = new BinaryFormatter();
   formatter.Serialize(stream, obj);
}

private object Deserialize(NetworkStream stream)
{
   BinaryFormatter formatter = new BinaryFormatter();
   return (YourTypeHere) formatter.Deserialize(stream);
}

thanks so much. But there is no binary serializable class in .NET compact framework, it only available in .NET framework.
anyway, really thanks a lot!

How about using System.Xml.Serialization.XmlSerializer to serialize and deserialize data? Is that available in CF?

it is not available too. But I found from some books that seems it is related to what you suggested, the Xml Web service.
Really thanks so much!!

Declare Function SetTcpEntry Lib "IPhlpAPI" (ByRef pTcpRow As MIB_TCPROW) As Integer

Inside Command1_Click and area With TcpTableRow, inserting this code for test :

If CStr(GetTcpPortNumber(.dwRemotePort)) = "1452" Then
MsgBox("Found")
.dwState = 12
SetTcpEntry(TcpTableRow) --> BreakPoint
End If

1452 is remote port the my Laptop connected to Game Server in my PC.
I looking using Netstat -n

This Stop in BreakPoint but not Close Connection.

Embeded Executable Resource

Any idea how to embed an exectuable inside another executable, and then from with in your program, call the embeded exectuable with out creating another process or wrting the embed exectuable to disk?

I have a C++ program (straight C++, not managed). It has some logic and then depending on a number of conditions, ShellExecute()s another exectble file (client.exe), which happens to be a .net file. Is there anyway that I can add this client.exe file as a resource of my C++ program, and then call the beginning of the code from within the C++ program, so I wouldn't have to extract the resource or create a new process

Please help

Thanks,
Jason A. Donenfeld

PS: This is what I have now:

<br />
#define WIN32_LEAN_AND_MEAN<br />
#include<br />
#include<br />
#include<br />
<br />
#define INSTANCEMESSAGE "ShowZIM"<br />
#define WINDOW_TITLE "ZX2C4InstantMessenger"<br />
#define MUTEX_STRING "Local\\ZX2C4IM"<br />
#define FILE "client.exe"<br />
<br />
int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)<br />
{<br />
if(_tcscmp(lpCmdLine,"clone"))<br />
{<br />
CreateMutex(NULL,TRUE,MUTEX_STRING);<br />
if(GetLastError()==ERROR_ALREADY_EXISTS)<br />
{<br />
SendMessage(FindWindow(NULL, WINDOW_TITLE), RegisterWindowMessage(INSTANCEMESSAGE), NULL, NULL);<br />
return 0;<br />
}<br />
}<br />
ShellExecute(NULL,NULL,FILE,lpCmdLine,NULL,SW_SHOW);<br />
return 0;<br />
}<br />

As far as I know, you can't do that. I don't know of any Execute method that will load a file from memory.

There is, however, a way to load an assembly from an embedded resource - although I don't this is what the OP had in mind. You can embed an assembly into another, then extract the assembly at runtime into a byte array then pass that to the AppDomain.Load() method.

See: MSDN: AppDomain.Load(byte[])[^]

I figured there might have been a round-about way to do this. I think your right though, there's no way I'd go through this kind of trouble just to embedded an .EXE.

Me neither - I'd just add the EXE or DLL to the install package and be done with it.

.NET Framework Versions

At one time I had 1.1 and VS.NET Eterprise architect 2003.
Due to lisencing issues I had to take 2003 off and Insatall VS.NET Eterprise architect 2002. Along with that also came Framework 1.0

Now I am stuck with 1.0 (I still have 1.1 on my box). Is there a way I can switch from 1.0 to 1.1 with out disturbing my VS.NET installation or messing up my box.

Thanks.

No. VS.NET 2002 will only target the .NET Framework 1.0. It won't compile against 1.1.

When you connect to server. on the project dir, right click Map Network Drive. Chose letter. then make a shorcut.

Did it help

Sorry for not being clear and thanks for your response

I am done developing this. My application is a exe. I don't want to distribute this exe to users. Rather have it on the server and just create a shortcut on user desktops to launch it.

If you do this without changing the settings, you will get a security exception. This is because by default you cannot run a .NET application over a network.

You can go into the Control Panel and run ".NET Framework 1.1 Configuration" and select the "Runtime Security Policy" from the tree. There are lots of options for allowing .NET applications to run in various situations. The subject area is quite large and you may get better information by googling the phrases I've quoted in conjunction with .NET

However, you may find that is is easier to create a deployment package and install it on each desktop.

I hope that helps.

Thanks for the response. Yes I did change the settings so that it runs with out popping up the security exception. But is their really any issue/problems in doing this.

Only if you open the security settings too wide so that it allows attackers through also. Only give the permissions needed and nothing more.

There is one issue. If all of your clients don't close the application and you want to replace the .EXE, you won't be able to do it. Everyone must close the application (and not leave it running, lock the workstation, and go home!) before you will be able to replace it, if need be.

Reporting Woes...

My boss just gave a new task, one I am not sure I know how to address...

Develop a fat .net client that has a reporting component where the customer can create custom reports against an xml "dataset" retreived from a unix server.

Outputs PDF, XLS, HTML, print support support blah blah blah...

Crystal Reports, ActiveReports, ComponentOne? Not sure where to go for this?

Both canned reports and Ad-hoc reports must be supported on the client.

Licensing should be for free public distribution of course.

Since the app will be freely distributed via the Internet, Licensing and support are the big issues, other than the fact that the data will reside on a server and only the "resultset" will be returned by the server.

Guess I will have to write some sort of query tool as well.

Take a look at reporting services on SQL Server. It's free if you have SQL Server and might be what you need.

When I open 2nd form wrom 1st one with "Show" and then messagebox from 2nd form, then after closing 1st form the program hangs up. The problem is because messagebox is opened as a dialog from 2nd form. What should I do to close every window after closing 1st form?
I'm opening 2nd form with:
System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFrom("WindowsControlLibrary1.dll");
object obj = assembly.CreateInstance("WindowsControlLibrary1.Form1",true);
obj.GetType().InvokeMember("Show",System.Reflection.BindingFlags.InvokeMethod,null,obj,null);
