I asked you for linfo and you've provided me with loginInfo structure. Follow these steps:

1. Find out how this linfo structure is being populated. Somewhere, a COleDateTime should be in place, hopefully.

2. You could compare COleDateTime variables to find out which is greater, just like you compare integers. This is because the COleDateTime class has the relational operators defined.

Is it possible to change the environment of a process?

Hi everyone!

My problem:
- I've got two programs
- both programs are located in the same directory
- each one writes data to a file named "c:\prog\bin\protocol.log"
- the file "protocol.log" get's corrupt

My question:
Is it possible to change the environment of one program so that it writes to another location?

Why dont you give the protocols different names? (log"Process ID".log)

You better write the logs in a user directorcy, are you get trouble on Vista. Blush | :O

Yes it is possible to modify the environment and/or hook NtOpenFile. But there are probably better solutions which should be tested first.

If the program is writing to its 'working' directory: Have you tried creating a shortcut to the executable and modifying the "Start In" directory?

Hi all.
See i am reading certain mails i want to sort them by mailDate in Decresing order...and write into xml..

Now i am reading the mail as it is and writing into xml file...

how i can compare it and write so it will be in ascending order..

for(int y=0; y<(linfo->ACL_STMAIL[0].iMBUserMailCount); y++) 							

								{						
									
									_tprintf("\nMails found between %s date and %s date\n",linfo->sStDate,linfo->sEndDate);					 									 
									mailDatee = linfo->ACL_STMAIL[y].cMBUserMailDate;
									mailDatee.Remove('/');										
									if(linfo->ACL_STMAIL[y].bMBUserMailHasAttachment)
									{
										//FileExt = strtok_s(string,"* ,",context);
											
										AttachCount=linfo->ACL_STMAIL[y].iMBUserMailAttachFileCount;	
										for(int i = 0;i < (linfo->ACL_STMAIL[y].iMBUserMailAttachFileCount); i++)
										{
                                          											elementName [0] = "NAME";
											elementValue[0] = linfo->ACL_STMAIL[y].cMBUserMailFromName;
											elementName [1] = "EMAIl";
											elementValue[1] = linfo->ACL_STMAIL[y].cMBUserMailFromEmail;
											elementName [2] = "DATE";
											elementValue[2] = mailDatee;
											elementName [3] = "TITLE";
											elementValue[3] = linfo->ACL_STMAIL[y].cMBUserMailSubject;
											elementName [4] = "BODY";
											elementValue[4] = linfo->ACL_STMAIL[y].cMBUserMailTextDesc;

Well, if you are using COleDateTime, you could use the relational operators ( == , != , < , > , etc.,) [^] of that class. The linked page has an example too.

if the format is always fixed (i.e. there must be two spaces between 20080430 and 8:36:05 in your sample string) then a lexicographic comparison is enough, that means strcmp will do the magic:

const char * date1 = "20080430  8:36:05"; 
const char * date2 = "20080423 13:49:19"; // note the alignment

int icmp = strcmp(date1,date2); 
if (  icmp > 0)
{
// here date1 is the latest one
}
else if ( icmp < 0 )
{
// here date1 is the earlest one
}
else
{
// I guess you can figure out what happens here
}

On the other hand. If the format is not fixed then you're a (actually not so much: it is fairly easy to repair it) unlucky girl.

The answer will be mostly dependent on the information provided in your question. I'd say the answer given to you was precise enough.

Have a look at CDialogBar class, quite easy to use! Will not be on the menubar though, will act as a toolbar.

Copy directory

There seem to be no mfc function for copying entire directory.

The closest match is MoveDirectory() which will result in one copy of the folder being moved.

Is there any way to do that?

Low-pass filter questions

jeremie.delaitre19-Jun-08 20:36

jeremie.delaitre

19-Jun-08 20:36

Hello,

I have curve data into an array and I need to apply a low-pass filter (Bessel and Butterworth) on it.
The sampling rate of my data is not constant (for example, I get a value at 1s, then 1.2s, then 1.8s...).
As I said, the curve data are in an array, and the corresponding timestamps are in another :
double time[] = { 1.0, 1.2, 1.8, ... }
double value[] = { 3.1, 4.4, 5.0, ... }

By reading wikis and web sites, it seems that applying a low-pass filter will attenuate the high frequencies (i.e. higher that the cutoff frequency). The attenuation will depend of the type of the filter (Bessel, Butterworth, ...) and its order.
Please tell me if I am wrong!

In other words and in my case, if I have two timestamps which are "to close" (for example : 1/(time[1]-time[0]) > cutoff), I need to modify the corresponding value (value [1]). The new value will be given by the transfer function (which depends, again, of the type of the filter and its order).
Is that right or I am totaly lost ?

If all of this is right, then, how to get the new value ? Taking a look to wikipedia tells me a lot about bessel/butterworth transfer functions, but I do not understand how to apply them.
Could someone provide me an algorithm ?

If all of this is wrong, then, could you please correct me ?

Thanks in advance.
