had simulated a 3 d array as follows
typedef unsigned short byte;
nbands=layers;
j=x_length*y_length;
byte**data_1=new byte*[nbands];
data1[0]=new byte[nbands*j];
for(int i=1;i<nbands<++i)
{
data1[1]=data1[i-1]+j;
)
now consider the 3d equivalent array to be[layers][y_length][x_length]
//assume the data is stored in data_1
suppose i create a data_2
byte**data_2=new byte*[x_length];
data2[0]=new byte[nbands*j];
for(int i=1;i<x_length;++i)
{
data2[1]=data2[i-1]+(nbands*y_length);
)
how to i transfer the data frm data_1 to 2
my req dimension nw wud be [x_length][layers][y_length]as comp to the first one
ie if layers=64
and [y][x]=[256][241]or something
wat wud function convertdata_1to2 look like???
i express my eq 3d matrices[layers][y][x]
please do help
thanks in advance

Please change your title, as 'repost' is not welcomed here, I suppose.

Three dimensions? I see two dimensions.

What is the purpose of the above code?
If you're interested in three dimensional arrays, you can just use them, can't you?

sir
i'm working on some interconversion between file formats..which requires the current structure
please suggest me a solution
|
|

What structure is required? Could you please elaborate a bit your requirements?

actually i'm working on reading a hdf file which has constituent datasets which have 2d dimensions,so is 1d array (corresponding to no of datasets)of 2d element(corresponding to the datasets themselves) wud be very convienient the no of datasets in my hdf file is 64 ,dimensions(241*256)..
i need the above req conversion so tat i can encode the information in tiff format

You know there are libraries [^] to deal with HDF files?

Your code appears a bit messy. Could you please state clearly what are you attempting to do (i.e. what is your input and what should be the ouput)?

I know, you already stated it. Anyway we can give help here on specific problems, hence: what is the specific obstacle at the moment (please be clear)?

Hi,
How can i merge two Xml files using VC++(console application)..im not allowed to use managed code.bcos our project is in vc++ only..
|
|
|
|

To do XML reading, writing and manipulation, you could use one of the many C++ XML libraries that exist, such as MSXML or libxml. Beyond that - well, it all depends how you intend merging the XML files, doesn't it.

Thanks for ur Reply...
Can i get any sample which uses MSXML for Merging Xml files....

Another one that seems popular (I have never used it) is TinyXml[^]
Not that the OP needs to worry about at this point.

RapidXML[^] (yes, it lices up to its name) is another one I've used. It's easy to incorporate it into your projects as well:
Entire parser is contained in a single header file, so no building or linking is neccesary

If I were a cynical person, I'd be suspicious that two posts asking how to merge XML files were seen in the forum on the same day, and that the OP of one of them replied to my reply in the other thread. Only if I were cynical, though....

"with parsing speed approaching that of strlen function"
That's sweet! Also Boost.PropertyTree looks interesting. Thanks!

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!

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.
