I am writing an application in C++ to monitor chat from multilingual chat rooms. I would like to be able to determine what language the chat is in, as in some rooms only certain languages are allowed. I was thinking of using the unicode ranges to determine whether the characters of the chat are in the allowed set - but this become difficult with the asian languages as the are over 200 different language sets defined. Does anyone know of an easier method of determining what language is being used?

Look up words in a tiny dictionary of commonly used language-specific words.
Examples for English would be: I, you, he, she, it, a, the, have, has, am, are, is.... (you won't need more than a dozen or so per language)
Making a mistake is of course possible, but if you scan input thoroughly enough chances are you'll determine the language accurately.
Of course, the issue must have been looked into by many philologists. Try searching the web.
Technically, if you wish to avoid this method all you can do is try checking character codes unless you want to mess with checking the current keyboard layout. I've never tried the latter but it looks like headache and guarantees absolutely nothing...

Thanks.
I had thought of your first method, but I think certain languages use similar words so the accuracy wouldn't be that good especially for chat as maybe only one of the words I am searching for would be used per chat line.
Haven't had much luck on the web either

specify INTERNET_FLAG_RELOAD flag to InternetOpenUrl function.
Forces a download of the requested file, object, or directory listing from the origin server, not from the cache.

I'm confused of frequently change openmode of database via ado-recordset,
the attitude of locktype also doesn't take function (m_pRecordset->LockType=..),m_pRecordset->AddNew() take a runtime error.how to solve this problem without chage the open statement in initializing(Read only when initial open)?

why not you use a command object _CommandPtr and try *Executing* the insertstatement? instead of using m_pRecordset->Addnew()?

Hi,
I use the FindFile(sCurrImgPath) and FindNextFile functions to search for files of the format file*.x (where the * is a number) in a directory. The problem is that these functions return the file names in the following order (for example):
file1.x
file10.x
file11.x
file2.x
file20.x
file3.x etc...
and I need the files in the order:
file1.x
file2.x
file3.x
file10.x
file20.x etc...
How can I do this?

That is how it will be because when comparing strings file10 is less than file2 so it comes up in the order.
If you have file numbering like file01, file02, you can avoid these problems. But you cannot expect this.

I don't have the files numbered this way, and I can't change their names...
is there a way to sort the names of the files after I get all of the file names?

CComboBox m_Combo;
m_Combo.Create(WS_CHILD,CRect(0,0,0,0),this,1);
m_Combo.Dir(DDL_ARCHIVE|DDL_DIRECTORY, _T("*.*"));
and you can inactive sort in the propery page

I don't understand what you meant...
did you mean to add to my project a combo box that will list the files, and then use it's sort property to sort the names?
|
|
|
|
|
CComboBox m_Combo;
CString m_str;
m_Combo.Create(WS_CHILD,CRect(0,0,0,0),this,1);
m_Combo.Dir(DDL_ARCHIVE, _T("*.*"));
for (int i=0;i

a combo box is a displaying matter.
what the guy does is a background treatment, typically for a controler...
moreover, you are using a MFC class when no way the guy said that it was using MFC...
very bad method so.

2 possibilities :
if you can rename the files, change file1.x, file2.x, to file01.x, file02.x, etc...
if you're not allowed to change the file names, then firstly search for "file?.x" files, then when you've got them, search for "file??.x"...
|
|
|
|
|
I can't rename the files... so I'll have to go for the second possibility.. 
but FindFile doesn't accept question marks, it accepts * to signify a wild card.
so when I write file*.x and file **.x, it gives the same result...
Is there a way to get all of the files that have one number after the file, then find all the files that have two numbers after the file, etc.?

Why don't you get the files in a linked list and then sort the list? In that case you can sort the list in any type of order you need. Basically, the suggested solution with the combobox does the same, but you can keep it all in your own hands just as easily. Suggestion for a linked list:
typedef struct _st_list ST_LIST;
struct_st_list
{
CString m_strFilename;
ST_LIST * m_Next;
};
ST_LIST * MyList = (ST_LIST *)NULL;
ST_LIST * NewList (void)
{
ST_LIST *r, *l;
r = new ST_LIST;
r->m_Next = (ST_LIST *)NULL;
if ((l = MyList) == (ST_LIST *)NULL)
MyList = r;
else
{
while (l->m_Next != (ST_LIST *)NULL)
l = l->m_Next;
l->m_Next = r;
}
return r;
}

Dear Visual C++ friends,
For example, there are some files with extension .doc in c:\test directory. How can I write code to find those files and get file names?
Once I get those file names I'll list them in a combo box.
Regards,
Joy Anne
