Snippet of the code not working could help us see where the problem may be...

I can Serialize And Deserialize In One Application .
i workinn Server And client Application so i need Send Struct to Client
when i serialize Struct and Send , in client Application can't Deserialize Struct

The problem is, the same assembly needs to be used to deserialize as the one that serialized it.

There's ways around this though, if you don't want to keep a separate assembly to maintain
on both ends.

Please post the EXACT exception message (entirely) and I'll show you an example...If you'd like.

You can get the message from the exception by wrapping your deserialize code in a try block and
adding something like

...    
    catch ( SerializationException^ e ) 
    {
        Console::WriteLine( "Failed to deserialize. Reason: {0}", e->Message );
        //throw;
    }

In order to serialize in one assembly and deserialize in another either you need to maintain same assembly in both applications or you use a technique described here:
Advanced Binary Serialization: Deserializing an Object Into a Different Type Than the One It was Serialized Into[^]

The example is in c# but you should be able to use the same principle in C++ .Net too.

Hope it helps.

When I Seriliaze Object In the File how To save Assembly Name And Typename with My self

Queue Problem

Hi,

I'm using a commandbox for the user to select commands and they pass these commands to a listbox and therefore whatever commands in the listbox are ran when the user clicks on "Run Commands" button.

The problem is if more than one command in the list box then only the first command is ran. If I try to add a queue behind the listbox then the program crashes.

Anyone have any ideas to solve this problem?
Cheers

<br />
<br />
//Button to run the commands in the list box<br />
if(lstCommands->Items->Count >0)<br />
{<br />
  if(lstCommands->Items->Contains("Move forward")) <br />
  {			<br />
this->lstLogCommands->Items->Add(numLog + "  Move forward");<br />
}<br />
 else if(lstCommands->Items->Contains("Move Back"))<br />
 {<br />
  protocol_test(3);<br />
this->lstLogCommands->Items->Add(numLog + "  Move Back");<br />
}<br />
else if(lstCommands->Items->Contains("Turn Right"))<br />
{<br />
 protocol_test(4);<br />
this->lstLogCommands->Items->Add(numLog + "  Turn Right");<br />
}<br />
else if(lstCommands->Items->Contains("Turn Left"))<br />
{<br />
  protocol_test(5);<br />
this->lstLogCommands->Items->Add(numLog + "  Turn Left");<br />
}<br />
<br />
numLog++;<br />
}<br />
else if(lstCommands->Text->Empty)<br />
{<br />
MessageBox::Show("No Commands selected","NoCommands",MessageBoxButtons::OKCancel,MessageBoxIcon::Exclamation);<br />
 }<br />
}<br />
<br />
//*******************************************************************<br />

Does that mean

queue<int> q;<br />

? If so you really need to figure out how to post code before you try to get us to decipher it.

is this also a posting mistake?

gman2008 wrote:
while (lstCommands->Items ->Count >> i)

because if you really have a right shift operator there then I guess you have no idea what you are doing. You need to go read some documentation on the '>>' operator[^]

It is hardly to find article or information on c++/cli .net asynchronous socket programming. I even cannot find a piece of it on internet. Any have it? Most i can find is in c#.

When i try convert and use this code as below:
m_mainSocket->BeginAccept(gcnew AsyncCallback(OnClientConnect), null);
AsynCallback^ pfnWorkerCallBack = gcnew AsyncCallback(OnDataReceived);

it show error like this:
error C3867: 'ServerChat::Form1::OnClientConnect': function call missing argument list; use '&ServerChat::Form1::OnClientConnect' to create a pointer to member (i try put full function prototype onClientConnect(IAsyncResult^ asyn) but still error)

error C3867: 'ServerChat::Form1::OnDataReceived': function call missing argument list; use '&ServerChat::Form1::OnDataReceived' to create a pointer to member

error C3350: 'System::AsyncCallback' : a delegate constructor expects 2 argument(s)

error C2065: 'null' : undeclared identifier

other errors just same with those listed. Help pls...

Hey mike, i did find and read articles often but problem is i cannot find any relevant information or solution. Thx for your reply but this help ntg.

Mark Salsbery29-Feb-08 6:48

Also, those C# articles can be helpful - The .NET framework is the same - so is the code logic. The
code syntax is pretty similar too.... Smile | :)

The first two errors are pretty obvious (or should be) from the error message. ..In C++ you don't get the address
of a member function that way anymore - you use the address-of operator, as shown in the error message.

Hey Mark, the c# articles really useful to get me in c++/cli. Smile | :)

Can u simply show me how to use the address of operator for a function to solve that error? Thx.

did you try this?

m_mainSocket->BeginAccept(gcnew AsyncCallback(&ServerChat::Form1::OnClientConnect), null);
AsynCallback^ pfnWorkerCallBack = gcnew AsyncCallback(&ServerChat::Form1::OnDataReceived);

Don't be overcome by evil, but overcome evil with good

Re: c++/cli asynchronous socket communication (solved but prompt out strange error)

7-Mar-08 20:07

By doing AsyncCallback(&Form1::OnClientConnect) the problems is solved but it still prompt a strange errors like this:

error C3352: 'void ServerChat::Form1::OnClientConnect(System::IAsyncResult ^)' : the specified function does not match the delegate type 'void (System::IAsyncResult ^)'

It is exactly the same type why it still happen to be an error?

I try put static void OnClientConnect(IAsyncresult^ ar) as fuction can solve it somehow but it prompt out error after put static to the function like this:

error C2227: left of '->Text' must point to class/struct/union/generic type
by right richTextBoxRcvMsg->Text don't have any problem.

error C2227: left of '->EndAccept' must point to class/struct/union/generic type
by right m_Socket->EndAccept(ar) don't have problem.

Someone help pls..
