You need to link LIBCD.lib with your application in your linker settings...

Project->Settings->Link->object/Library Modules. (Follow these steps, if you are using VC++ 6.0)

Pipes Question ?

Hi all,

OK, I'm trying to create a pipe server and pipe client, but the thing is ... it's working if I test it on a local computer, but when I try and test it over a network ... nothing, I think the problem is my pipename.

This is what I've done so far.. (some less important code has been excluded)

<br />
//SERVER<br />
LPTSTR lpszPipename = TEXT("\\\\.\\pipe\\hello");<br />
hPipe = CreateNamedPipe( <br />
          lpszPipename,             // pipe name <br />
          PIPE_ACCESS_DUPLEX,       // read/write access <br />
          PIPE_TYPE_MESSAGE |       // message type pipe <br />
          PIPE_READMODE_MESSAGE |   // message-read mode <br />
          PIPE_WAIT,                // blocking mode <br />
          PIPE_UNLIMITED_INSTANCES, // max. instances  <br />
          BUFSIZE,                  // output buffer size <br />
          BUFSIZE,                  // input buffer size <br />
          NMPWAIT_USE_DEFAULT_WAIT, // client time-out <br />
          NULL);<br />
<br />
//CLIENT<br />
LPTSTR lpszPipename = TEXT("\\\\.\\pipe\\hallo");<br />

The thing is what is the correct pipename to give the server and the client to communicate over a network???

Can anyone help???

Thanx alot

Regards

You're using "." for the machine name which always refers to the local machine. You need to replace "." in the pipe name in the client code with the name of the machine on which the pipe server is running. For the server code, you can leave it as "." since the server will be running on the local machine.

Hi, what about using an IP address?

Will it work?

Cause I keep getting a error -> Could not open pipe.

I changed the client side to:

<br />
//CLIENT<br />
LPTSTR lpszPipename = TEXT("\\\\lw09228109\\pipe\\hallo");<br />

And the server to:

<br />
//SERVER<br />
LPTSTR lpszPipename = TEXT("\\\\.\\pipe\\hallo");<br />

Thanx

Regards

Don't know. Give it a try and see what happens Smile | :)

The hostname might not be visible from the client which is why its not working that way, which would be a network config issue.

Well, if I use the host's IP or computer name on the remote (client) machine to connect to something like a shared folder (on the host computer) there is no problem.

mmmm... I have no idea ... Confused | :confused:

Thanx for the response.

Well it works using an IP address (on a local compauter), but still not over a network ... lol

maybe there's a network config issue, firewall, etc. no idea why it wouldn't work.

So in your opinion would a Symantec Gateway, cause the problem?

Hi!

I found a lot informations about toolbars here (http://www.codeproject.com/docking/).
But I'm really looking for an answer to this question:
Is it possible to add MFC-Toolbars to embedded Containers other than the Main-Application Window?
Example: VS.Net (7.1) - there nearly every Container (like "Properties", or "Class View") has its own Toolbar. Could this be made with MFC - Methods?

Hope this was understandable ... I'm still not really into this MFC-Library.
Thanks in advance!

MFC is a class library encapsulating various parts of the Win32 OS API and in some cases adding pre-built feature or functionality. Since it is for C/C++ you can easily access the OS APIs whenever needed. So ....

you mean, only the project, of the generated bin (exe or DLL) ?

if you mean the project, rename the corresponding file. otherwise, look into the project settings.
