If you have UNICODE build environment ( i.e _UNICODE is defined )then you will have to do the following

//#include "atlconv.h"

USES_CONVERSION;
LPCSTR lpcstrNonUnicode = W2A(( LPCTSTR )csStringToConvert );

If you have a non UNICODE ( i.e. _UNICODE not defined ) build environment

Then just a simple assignment is needed...

LPCSTR lpcstrNonUnicodeString = csStringToConvert; // Calls operator LPCTSTR()

I am trying to write a program to get list of files in a folder sorted by created Date and Time. Is there a function to do the same.

Can anyone reply me on this......

Thanks

Does WIN32_FIND_DATA suits your needs;
typedef struct _WIN32_FIND_DATA {
DWORD dwFileAttributes;
FILETIME ftCreationTime;
FILETIME ftLastAccessTime;
FILETIME ftLastWriteTime;
DWORD nFileSizeHigh;
DWORD nFileSizeLow;
DWORD dwReserved0;
DWORD dwReserved1;
TCHAR cFileName[MAX_PATH];
TCHAR cAlternateFileName[14];
} WIN32_FIND_DATA, *PWIN32_FIND_DATA;

Somethings seem HARD to do, until we know how to do them.

There is an API CompareFileTime. Along with this API you can use GetFileTime API to get the time of the two files.

Take a look at qsort for sorting.

I get txt files to upload into my system
say
1) 00002.txt 01/11/2006 11:00 AM
2) 00001.txt 01/11/2006 10:00 AM
3) 00003.txt 01/11/2006 11:10 AM

I need to pick files by time and upload in the order 2) then 1) then 3)
Number of files is not limited.

I am currently using FindFirstFile and FindNextFile and the DWORD as mentioned in the other post. But this sorts by FileName.

Not necessary, you can use FindFirstFile and FindNextFile to get file information ( which is better than GetFileTime ). Then sort them based on the file creation time.

Use CompareFileTime.

qsort also helps. You can specify a custom compare function callback and just return the value returned by CompareFileTime from this callback function because that is what qsort expects.

Is there any way i can change the color of a command button directly without using the class provided by this link. Also this link states that we cannot change the color of a command button directly. http://www.codeguru.com/cpp/controls/buttonctrl/advancedbuttons/article.php/c8395[^]
Thanx in advance

Thank you so much for all the replys. As said by Nibu babu thomas, WM_CTLCOLORBTN cannot be used for command(push) buttons. So, can anyone enlighten me.
