At the completion of AcceptEx, I called WSARecv, it return 0, and data can be got immediately, nothing wrong. Then until WSARecv return SOCKET_ERROR I put another WSARecv, ensure that WSAGetLastError()==WSA_IO_PENDING. But it can't receive data from the client any more, why?

I'v not seen any document that says WSARecv can return 0 in IOCP model.
I'm not sure however.

It says so right in the MSDN docs for WSARecv.

Hi,
I have few questions.
i have read some articles on https+vc++ in code project. Thanks to the guys for articles.
1. If i need to do a https request(ssl+client crtification) to a server which is the library i need to use for VC++ dll(not a desktop application).
winInet or WinHttp
2. what are the sequence of operations(API methods) to send the https request.
3. i have client certificate, and i want to select this particular client certificate with the https request.
thanks

i am able to makes a https connection using wininet,
but how can i handle the response.
i am using the InternetReadFile after the request is sent.
This method reads the contents of the file, but i want a API method which responds only the output of the object file(my case it is servlet).
thanks

Is FName the full path to the file?

Hi Nibu thomas,
List box contains a data like
C:\dir\filename.ext
i used the F5 and checked the value of FName i am getting Error symbol "FName" not found.
Is the code correct to get the value of the selected item from the list box ??

The Fname should be in the format of '\\' instead of '\'
for e.g
C:\\path\\filename.extension instead of C:\path\filename.extension

This answer is not correct. The double backslash is only neccessary if you use a literal string in your programming code. Here you just read the name entered in a listbox. I recoomend to use the source level debuger and place some breakpoints. You should always check following things: is the function actually called? Does the Listbox provide the correct handle? (I also recommend to handle LB_ERR so you see it if something is wrong)Do you get the correct string back from the listbox? Is your call to ShellExecute handled correctly? Does it give back an error message?
I really do not understand why you need to ask such a question in the forum. You reaaly should invest some time to learn how to use the source level debugger and how to read the documentation.

Well you have to grab the device context of the Console Application. Then use normal SDK paint functions to paint to this device context.
