i all,
I am trying to convert a file path ( in UNC format) using
GetShortPathNameW API. But It fails, saying that

"The filename, directory name, or volume label syntax is incorrect."

Anybody knows what is issue here?

Here is the sample code

DWORD dw =0;
wstring m_UNCPath = L"\\\\?\\UNC\\server_ip\\ONTAP_ADMIN$\\vol\\vol0\
\home\\testdir4";

// here server_ip is my machine ip of intranet

long length = GetShortPathNameW(m_UNCPath.c_str(), NULL, 0);
DWORD dwerror = GetLastError();

// dwerror return "123" and length =0

length += 2;
wchar_t* buffer = new wchar_t[length];

dwerror= GetShortPathNameW(m_UNCPath.c_str(), buffer, length);

Note: I tried to create a file insame path using CreateFileW api and
things worked.

Hello,

Is there a way to determine which version of MSDN Library is installed (on
my system)?
Microsoft geniuses don't seem to provide this info.

Thanks,
Boris

Hi

I am trying to write a program to read the RTS line on a serial cable.
I am using windows 2000 and Visual Studio 2005. How would I go about
doing this. I am a relative Noobie with C++
thanks

Hello

I need to send a double across a network connection and thought
easiest way is to convert to a 64 bit number - ie __int64 and then
send that.

However if I do this:

double d = 3.3;
__int64 i64;
i64 = (__int64)d;

I lose the floating point.

I assume floating point numbers can be stored in this way?

I also need to be able to re-assemble the double at the other end.

Hi, I am new to win32 programming. I wanted to fetch the OS version
through VC++ code. I found something like System.Environment.OSVersion
but not getting how to use it.

For System, Environment its throwing undeclared identifier. What
header i should be adding to get these working?

Hi,

Whenever a dll is loaded into a process, the 'DllMain' will be called. I
want to know that if there's a global variable of an instance of a
class, say class CSingle, will the instantiation of this variable be
guaranteed to be performed once? E.g.

CSingle _single;

BOOL WINAPI DllMain(...)
{
...
}

Will the constructor of _single be called only once, no matter how many
times this dll being loaded?

Because in .Net framework, the CLR loader would make sure that the
constructor of a 'static' member is called only once. This made easy to
implement the 'Singleton' pattern.

Thanks,
David
