but the sender knows how much datas it sends...
so, you could send first an int with the number of bytes that are about to be received, then send the packet.
This way, the receiver will catch the value, and enter a while loop until that amount of data is not received entierly...
is is good for you like that ?

thanx man
that did solve some of my problem
but in my case the sender is a third party system
hence i donot know how much the sender is going to send
I cannot pass an "int" there can i?
hence am still stuck in the same old problem

Please can you show me any links where I can get information about working with DEBUG in Visual C++.Net
cause Im experiencing big difficulties in error finding.Thank you.

you can add some TRACE(), some breakpoints, and look where the program freezes

How can I create a program that is executed when the computer is switched on. I want to do this to check how many times the internet has been accessed using the internet explorer

wow, don't mix everything. when the computer "switch on", the BIOS loads the operating system, which can be Windows for example. then, windows loads all its components, and only there, is ready to load a session (user).
you can add you program into the start folder of the start menu (not sure of the right path in english versions of windows, and depends also of the OS), or add a key in the registry in the list of the programs that are to launch when a user's session starts.

Hi.
I am newbie to this website. I have some questions. My first question is about how to implement self-extracting installers? These programs have the ability to extract files stored within their executables. Secondly, most programs including compilers have the ability to create brand new .EXE files. I know that i can write an interpreter of any new or old language but how to make an independent EXE which can run without the interpreter?
Thanks in advance.
Waiting for your replys.
I just looked around this website. I must say that it is a very nice site for programming. Comprehensive articles are also available. A complete separate section for MFC controls, including subclassing, etc. I also liked the DirectX section. Complete game making like Tetris, RaceX, etc. is given which helps not only to understand game programming but also to inspire our own ideas. Keep up the good work

If all you need to do is create a single-EXE installer, then try Inno Setup[^].

For this i want to get from the WEB server the client certificate object.
I have a problem to send the request to the server.
This is my code
HINTERNET hOpen, hConnect, hReq;
DWORD dwFlags = INTERNET_FLAG_NO_CACHE_WRITE |
INTERNET_FLAG_KEEP_CONNECTION |
INTERNET_FLAG_IGNORE_CERT_CN_INVALID |
INTERNET_FLAG_IGNORE_CERT_DATE_INVALID|
INTERNET_FLAG_PRAGMA_NOCACHE;
char *lpBuffer, szData[51];
INTERNET_PORT dwPort;
wchar_t* accept[2]={L"*/*",0};
if ( !(hOpen = InternetOpen ( "HeadDump", INTERNET_OPEN_TYPE_PRECONFIG , NULL, NULL, 0) ) )
{
ShowError ( GetLastError(), "InternetOpen");
return false;
}
if ( !(hConnect = InternetConnect ( hOpen, url, dwPort,""/* user*/, ""/* password*/, INTERNET_SERVICE_HTTP, 0 , 1) ) )
{
ShowError (GetLastError(), "InternetConnect");
return false;
}
if ( !(hReq = HttpOpenRequest (hConnect, "GET", url, "HTTP/1.0", "", (const char**) accept, dwFlags ,1 )))
{
ShowError (GetLastError(), "HttpOpenRequest");
return false;
}
again:
//Resolver::Trace("Send Request = " + data);
std::string header = CONTENT_TYPE_STR;
if ( !HttpSendRequest (hReq, // handle from HttpOpenRequest
NULL,0, NULL,0) )
{
ShowError (GetLastError(), "HttpSendRequest");
dwFlags |= SECURITY_FLAG_IGNORE_UNKNOWN_CA |
SECURITY_FLAG_IGNORE_REVOCATION |
SECURITY_FLAG_IGNORE_REDIRECT_TO_HTTP |
SECURITY_FLAG_IGNORE_REDIRECT_TO_HTTPS |
SECURITY_FLAG_IGNORE_CERT_DATE_INVALID |
SECURITY_FLAG_IGNORE_CERT_CN_INVALID;
if ( !InternetSetOption (hReq,
INTERNET_OPTION_SECURITY_FLAGS,
&dwFlags,
sizeof (dwFlags) ) )
{
ShowError(GetLastError(),"InternetSetOptionFailed");
return false;
}
}
I'm new in VC++.

MFC Supports Print preview only for applications with Document/View Architecture. I'd like to print from the Modal dialog and also want to have Preview Dialog. Any Samples already there?
|
|
|
|
|
There sure is. Take look in the printing section. I have presented a base class to use instead of CDialog there which gives a CDialog the same interface as a standard CView for printing
If you vote me down, my score will only get lower

If C++ already supports the C Standard Library, why do
we need to declare extern "C" when using C-linkage?
When do we use extern "C"? Is this compiler-specific
feature? Or is it defined in the standard ANSI C++?
On MSDN, it says Microsoft C++ supports the strings
"C" and "C++" in the string-literal field. However,
I have never seen something like extern "C++". Has
anyone seen it? Will we ever need to use extern "C++"?
Thanks

Hello Alex,
The extern "C" declaration is used to tell the C++ compiler not to mangle the symbol which is being declared.
When the C++ compiler encounters a function name like "DisplayCurrentThreadId()" which has not been declared as extern "C", it will emit a symbol for it which will look like the following :
?DisplayCurrentThreadId@@YAXXZ
The actual symbol produced depends on the compiler used (the above was produced by VC++ 6.0). This symbol will be used in the resulting OBJ file for linking purposes.
C++ has a variety of reasons for symbol name mangling, of course. But the reason for the mangling of function name (both class functions and global ones) is to enable function name overloading (i.e. using the same function name with different parameter types).
If extern "C" was used to declare the function, the symbol produced for it could be :
_DisplayCurrentThreadId
This depends on the compiler used. But the bottom line is that no function name overloading will be allowed (since the C language does not support this, hence extern "C").
Hope this helps.
Best Regards,
Bio.

Bio,
Thanks for your reply. I have one more question, does
the term extern "C" has anything to do with the storage
specifier extern?
Now that I understand name mangling, I wonder if extern "C"
is a C++ language feature, or is it compilers' feature?

no, not at all.

extern C++ is defined in the standard to mean do whatever the compilers default C++ is.
since this is the default it is almost never used.

i already got CxImage to read/view TIFF files... i searched it here in codeproject..
TIFF is a file format for handling fax images.. Its multi-page because, one .tif file can have 1 or more bitmap( frames) on it....

How can I find out if the window with input focus belongs to a certain process?
I do have a process handle, basically, I want to know if a child process has input focus.
we are here to help each other get through this thing, whatever it is Vonnegut jr.

You can call GetWindowThreadProcessId() to get the process and thread IDs that created a window. Not sure how you convert from a process ID to a process handle, but hopefully that'll help.
