Ok, I am sorry.
What it is basically doing is:
(1) taking an input XML file, and extracting just the <Body></Body> node structure, we'll call this the 'nodeBody'.
(2) With the 'nodeBody', it then checks if there is a <IRMark></IRMark> node within it, if there is it deletes the <IRMark></IRMark> node from the 'nodeBody'.
(3) With the resultant 'nodeBody' node it does a C14N Transform, the result of which, we'll call the 'result'.
(4) The 'result' is then passed through to a SHA1 hash algorithm, the result of which we'll call the 'digest'; (a byte[] of size == 20 bytes).
(5) The 'digest' is then converted into a Base64 string, the result of which we'll call the 'IRMark'.
I am ok with (1), (2), (4) and (5) above. BUT I would appreciate PLEASE PLEASE how on earth to do a C14N Transform in MFC C++ (unmanaged).
In C# I can do this as follows, but I am not allowed to use .NET in the project I am working on:
/**************************************
* Get the <bod></body> part of the xml:
* ************************************/
XmlDocument doc = new XmlDocument();
doc.PreserveWhitespace = false;
doc.LoadXml(xml);
XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("env", "http://www.govtalk.gov.uk/CM/envelope");
nsmgr.AddNamespace("ctf", "http://www.govtalk.gov.uk/taxation/CTF");
XmlNode node = doc.SelectSingleNode("//env:GovTalkMessage/env:Body", nsmgr);
doc = new XmlDocument();
doc.PreserveWhitespace = true;
doc.LoadXml(node.OuterXml);
nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("env", "http://www.govtalk.gov.uk/CM/envelope");
nsmgr.AddNamespace("ctf", "http://www.govtalk.gov.uk/taxation/CTF");
node = doc.SelectSingleNode("env:Body/ctf:IRenvelope/ctf:IRheader/ctf:IRmark", nsmgr);
/**************************************
* Remove <IRMark> node
* ************************************/
if (node != null)
{
XmlNode nodeIRMark = node.ParentNode;
nodeIRMark.RemoveChild(node);
}
/**************************************
* Transform the body:
* ************************************/
XmlDsigC14NTransform c14n = new XmlDsigC14NTransform(true);
c14n.LoadInput(doc);
c14n.Algorithm = "http://www.w3.org/TR/2001/REC-xml-c14n-20010315";
Stream stream = (Stream)c14n.GetOutput(typeof(Stream));

If you are looking for a XML parsing library, you can take a look at tinyXML[^]

Thanks. I'll investigate that tomorrow.

How to get local time in seconds?
I am using MS Visual Studio 2005.
I could get UTC time in seconds below.
Are they correct?
Thanks!
#include <time.h>
#include <sys timeb.h="">
double Clock::getUtcSeconds()const // returns UTC time in second
{
time_t UtcTimeValue;
return time(&UtcTimeValue);
}
string Clock::getUtcHMSTime()const
{
char buffer[10];
string strUtcTime;
time_t UtcTimeValue;
time(&UtcTimeValue);
struct tm* UtcTime = gmtime(&UtcTimeValue); //convert the calender time to UTC time
strUtcTime+=itoa(UtcTime->tm_hour, buffer,10); //convert to decimal number
strUtcTime+=" : ";
strUtcTime+=itoa(UtcTime->tm_min, buffer,10);
strUtcTime+=" : ";
strUtcTime+=itoa(UtcTime->tm_sec, buffer,10);
return strUtcTime;
}

We want to keep our system cross-platform.
Any ANSI standard way to get local time in seconds?

To bad you didn't include that requirement in your first post I might not have wasted my time giving you an answer that you can't use.

I have tried many ways.
The following worked.
double Clock::getLocalSeconds()const // The local time is hours behind. All else are the sams as UTC time.
{
time_t UtcTimeValue;
time(&UtcTimeValue); //get the system time, which is UTC time
struct tm* UtcHMS= gmtime(&UtcTimeValue); //convert it to struct tm*, which is UTC time
int utcHours = UtcHMS->tm_hour;
time_t LocalTimeValue;
time(&LocalTimeValue); //get the system time, which is UTC time
struct tm* LocalHMS = localtime(&LocalTimeValue); //convert it to struct tm*, which is the local time
int localHours = LocalHMS->tm_hour;
double diffHours =utcHours - localHours;
return ((double)UtcTimeValue - diffHours*SECONDS_IN_HOUR);
}

You are in the best position to determine that.

You are making an assumption here that a colon is always the separator.

And I provided you with the names of two functions to do just that.

if you see MSDN it writes:"changes the position and dimensions of the specified window" and also you can retrives current position of a window if you need

Great, it can be a lot of fun. Here is a "tip"... they hide all that information in the DOCUMENTATION[^] so that really beyond breathing the only qualification you need to be a windows developer is READING.

Hi,
I am looking for information on how to retrieve a drive's drive letter given the drive's device path (eg: \\?\ide#diskibm-dtla-307030_________________________tx4oa50c#5&230d196c&0&0.0.0#{53f56307-b6bf-11d0-94f2-00a0c91efb8b}. I get the device path by registering for device notifications for the GUID_DEVINTERFACE_DISK class and processing the DEV_BROADCAST_DEVICEINTERFACE structure received as part of the notifications.
I tried to do this by matching the device type and device number retrieved by sending IOCTL_STORAGE_GET_DEVICE_NUMBER to all drives on the system, but this method seems to fail if there is a RAM drive on the system. I get multiple drives with the same device type and number. Is this expected behaviour?
Is there a more reliable and simpler way to do this? Any help is greatly appreciated.
Thanks,
Priya
