Mapped drives are maintained per context.
So a mapped network drive of one user may not be valid for another user.
It is also dependent on the user privileges.
So Z: may be mapped by 2 different users on 2 different locations.

Hi,
I have created client and server application that uses
sockets for communication. But only single client can connect to server.
I have to connect multiple clients to same server.
Can anybody help me?
Thanks in Advance
|

You will need a multi-threaded program to handle multiple clients.
One dedicated thread will only wait for new client connections and will not do any other processing.
As soon as a client connects, a new thread is created to handle that particular client.
Either this or you can create the server using IO completion ports.

"you can create the server using IO completion ports".
Can you please explain?
|
|
|
|
|

I have created separate thread for multiple clients.
In that case also connection failed from more than one client
|
|
|
|
|
It looks like your server is not keeping the wait for the next client. Can you show your server code ? that waits for the next client?
|

In server I have derived class from CAsyncSocket and had overrided OnAccept function
I am creating new thread from OnAccept function and wrote send,recieve functionalities inside the thread procedure.I have not added wait in server because OnAccept will be invoked when client tries to connect.
Can u please mention what is the problem??

Haven't used MFC for sockets sorry.

Is it possible with winsockets?

You cannot directly access a C# class in VC.
You will need to create a COM Callable Wrapper (CCW) from the C# class.
Look at the documentation on how to create CCWs.
Then you can access it from VC like you access a COM component.

Shouldn't that be Class1 instead of _Class1?

Hello Friends i am facing a problem of CString Memory Leaks in VC6.0 in the Release mode i need some patches to ovvercome the Error. How to Fix The Bug Without changing my application
Hi this Ravinder

Neither here nor the other time you asked this question have you given any objective evidence of why you believe there to be leaks in CString. As I stated before, look at your own code - the likelihood of your code being incorrect is much, much higher than the likelihood of the code in MFC being incorrect, especially when it's a version of MFC that's had 11-12 years of exposure.

I am new to visual C++ and now i am working in a project of assessment tool. I want to generate dynamic controls like text box, combo box, static text dynamically. Can any one help me out from this?
|

The API to do this is CreateWindow.
The first parameter is a class name.
The class name can be a user defined class name or predefined class names.
Predefined class names like EDIT, COMBOBOX, STATIC, BUTTON etc. exist to create the standard controls.
Please refer to the documentation of CreateWindow for more details.

What kind of application is yours? (Dialog/SDI/MDI using MFC or simple Win32 App)
If you are using MFC, create a member variable of CEdit, CComboBox, CStatic, etc. And in the OnInitDialog (in dialog based) you can create them using Create().
In the case win32 app, you can use CreateWindow with specific class name.
See this[^]

i am working in a project in mdi using mfc vc++ 2005
i want to create that controls dynamically according to end user's wish. for an example, when the end user need a text box, then dynamically a text box should come in that form

So MFC classes CEdit, CComboBox, etc. can be used.
karthik11k wrote: want to create that controls dynamically according to end user's wish
You can think about a linked list to keep the control objects. Check the MFC's CPtrList class. You need to create the controls (using new) and keep them in the list. And once you finished using them "delete" it.
