What are the equvalent functions in WINCE?

Hai!

I am using JASPER library for a WINCE application, it has some WINCE unsupported functions lie open(), close (), tmpfile () etc. I could replace most of the functions with those supported in WINCE, but i couldn't replace two functions required in jas_stream.c and jpg_enc.c, the two files use
tmpnam() and tmpfile() functions in jas_stream_tmpfile () and jpg_encode () functions
sample code is below

tempnam (obj->pathname); // within jas_stream_tmpfile () function

and

if (!(output_file = _tmpfile())) //// within jpg_encode () function

{
..
}

What are the eqivalent functions of tmpnam() and tmpfile () for WINCE, i reffered the following : http://support.microsoft.com/kb/99456
Please tell equivalent functions or any workarround so that the overall functionality is not affected.

Thanks!

What is the functionality of these 2 functions?
From the name of it, it looks like the following 2 functions that are available in CE.

GetTempFileName<br />
GetTempPath

Actually that part of code designed in jas_stream.c and jpg_enc.c (which are present in Jasper folder of CxImage) is not even clear to me!!
http://www.codeproject.com/KB/graphics/cximage.aspx
so i am confused to what must be the values of the parameters

As of functionality of tmpname (), it chooses a temporary file name
and tmpfile () creates a temporary file and returns a pointer to that stream.

Thanks!

recover encrypted file from NTFS partition

Hello All,

I have seen the NTFS undelete code on this site. I have also created a similar application to create a copy of file by reading its information from the metadata files on NTFS. The undelete code helped me a lot.

Now I want to create a copy of encrypted file. I have retrieved the EFS attribute from the MFT record and copied encrypted source file's data to destination file. But I could not find structure for EFS and do not know how to decrypt the file's data.

Can anyone give me a idea of how can I decrypt file's data using the information from the EFS(Encrypting File System) attribute ?

Thanks.

Another way of specifying the library you want to link against is to add a line like this to one or more of your .cpp files:

#pragma comment(lib, "name-of-library-file, e.g. user32");

This adds something to the compiled object code that tells the linker that it should link against the named library.

In addition, you need to specify the directory containing the library in the project's properties, in the Linker->General->Additional Library Directories property.

How to create a drive mount?

I'd like to create a mountable drive -- a sort of network drive which I can control the contents of.

Any good clues to point me in the right direction?

I'd like to be able to mount "myspecialnetworkdrive" to my Z: drive.
I'd like the file list, and file contents to be under my program's control -- i.e. I would be the network source of those.

you can always call the process subst

SUBST [drive1: [drive2:]path]
SUBST drive1: /D

drive1: Specifies a virtual drive to which you want to assign a path.
[drive2:]path Specifies a physical drive and path you want to assign to
a virtual drive.
/D Deletes a substituted (virtual) drive.

Type SUBST with no parameters to display a list of current virtual drives.

Hi,

im using Win32 Console project..

The first thing you need to do is understand the contents of the two different files and how they should co-exist under a single root element (for that is a requirement of XML). One options could be:

<Root>
   <first-file>
      <!-- Put the contents of the first file here -->
   </first-file>
   <second-file>
      <!-- Put the contents of the second file here -->
   </second-file>
</Root>

But really, it depends on your requirements!!!

BTW - if you're asking technically how you might do it? Use MSXML or libxml to read the two files in. You then have access to the DOM of each XML file. Create a third DOM by combining the two existing DOMs in the way you've decided is best. Write out that third DOM to a file and voila! you have a merged XML file!

Length of non-english user name

English user name (logon name - not real name) can be displayed properly by 12 ASC characters.

I am not sure if 6 WORD characters (same size as 12 ASC chars) are good enough for user name in all other languages.

assume there are over 100K of users in each of non-english language.

If you know any language other than english, please give me suggestion, because length of user name is related to database and hard to be changed afterwords.

thanks.

You need 1 byte to store 1 ASCII character.
You need 1 or more bytes to store UTF encoded characters.

In Windows, UNICODE takes 2 bytes for 1 character.
You should be able to do your calculations based on this.

SQL Connection with C++

Hi Guys

I'm working on CMS Project, this is big project.
i 'm developing a Server so that client send data to Server, and Server will insert or query data to/from SQL Server 2005.

my question is:

1 - When client send data to Server. i open new Connection -> insert data to SQL then close Connection OR i only open connection at starting CMS Server and then client send data to server -> insert data direct to SQL Server, because Connection always opening. Client will send too much Data to CMS Server

2 - Do i need make 2 connections:
- 1 For Update Database(Insert,Update,Delete) always Open
- 1 For Query Data. i mean if 1 Client send request to Query Data from CMS Server. At that time CMS Server Open connection to SQL Server -> Query Data -> Close Connect

I mean 1 connection to Update Data always Open, 1 connection to Query data always Open and Close data. because Client sometime send request to get data.

Thanks and best regards
THien Nguyen

it depends if database connection is very fast.
Eg, if server and database are on same local network, you may close connection after doing something. Otherwise you have to let the connection open for lifelong, or server is too tired with database connection.

2 connections are absolutely bad design, if you want to limit query/update for a user, you can add limitations (such as doing only once in 5 minutes) to his ip (socket).
