See
WIN32_FIND_DATA m_data;
HANDLE hFile;
hFile=FindFirstFile(filename,&m_data)
if(hFile==INVALID_HANDLE_VALUE)
else
FindClose(hFile);
</code>
or see _access

Does anyone know the correct grammar for allocating a multidimensional array on the heap?
I have tried:
CHAR **Z = new CHAR[15][10];
CHAR *Z = new CHAR[15][10];
Upon further investigation is appears that C++ treats multidimensional arrays as distinct data types. This means that the problem in the above examples is that it can't assign a multidimensional array TYPE to any of the pointer types I have tried.
It has no problem, however translating between simple pointer types and SINGLE dimensional arrays. I suppose that the language is required to keep track of the number of elements in each dimension, so that it can perform the proper indexing when you supply subscript operators. So this must be the reason that the arrays are incompatible with simple pointer types, because simple pointer types do not carry such information around with them.

I think if you declare a pointer in this manner:
CHAR (*Z3)[10];
then you can assign any bi-direction array having 10 columns:
Z3 = new CHAR[15][10];
. . .
Z3 = new CHAR[50][10];
. . .
CHAR tab[30][10];
Z3 = tab;
It is easy to access an element:
I = Z3[2][7];
This approach can be used for multi-dimensional arrays too:
CHAR (*Z4)[10][30] = new CHAR[15][10][30];
int k = Z4[1][2][3];
Since for indexing the compiler does not need to know the first size of the arrays, it can be a variable:
Z4 = new CHAR[m][10][30];

Hi, it works! Thank you so much.
I wish I knew the theory behind why the declaration has a different meaning if you put the pointer name inside parenthesis.
Thanks again!

I didn't get that answer so plz send me clearly. In my program iam created XML file I want to add the files to that.plz any one give me the solution

This is Brute force method in which you can use the Format of CString to put the value in the text using the xml format and save it in .xml format .
fstream m_fXmlWrite;
sAddHeader.Format(""<"?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>"); m_fXmlWrite<<sAddHeader<<endl;

hello every1!
I am creating a simple static library file. I hava a string table in a library. These is a function getString which retrieves string from a string-table.
Now i have to use LoadString function in getString.
int LoadString( HINSTANCE hInstance,<br />
UINT uID,<br />
LPTSTR lpBuffer,<br />
int nBufferMax<br />
);
Then in this case what should be the first argument for the LoadString(). n how should i get this hInstance??
Thanks in advance!

hi,
use AfxGetInstanceHandle() to get the first value of LoadString()

In addition, note that instead of ::LoadString you can use the similar member of CString class. In this case is easier to load strings of any length.

hi!
Thanks for the replies!
there is another problem! I am bulding this project without MFC support. So I selected New->Win Static Library. Also i unchecked MFC support.
Now while calling this getString method, i need handle for the application which is using the library. When i tried defining getString prototype, it gives me error as HINSTANCE is undefined identifier.
I am defining getString as
class CCommonStrings <br />
{<br />
public:<br />
void GetString(HINSTANCE hinst);<br />
CCommonStrings();<br />
virtual ~CCommonStrings();<br />
<br />
};
what should be done here?? Is HINSTACE only avlble in MFC?

So you actually are building a static library, and not an MFC static DLL. In this case, I think you can use
HINSTANCE hInst = (HINSTANCE)GetModuleHandle(NULL);
The HINSTANCE type is defined in a Windows header file. You should include it after stdafx.h :
#include "stdafx.h"
#include <windows.h>
Or better put #include <windows.h> into stdafx.h and rebuild the project.

hi viorel!
thx a lot buddy! that solved my problem!

hello guys!
i am facing new problem now!
I checked everything but i am getting error 1814
i.e "The specified resource name cannot be found in the image file. "
Someone told me that we can not use string tables in a static library. And if we use it, then we have to include that string table in the apllication along with a library.
is it true!
