its not possible with ontimer event

You can of course do it in the OnTimer event but that won't be a good idea. You should use a thread which executes itself evey minute.

Banks K wrote:
please tell me how it is possible

When the OnTimer event is fired, you can get the current system time and date using GetSystemTime.
If the values in the structure for GetSystemTime match with what you have, You can execute your exe.
Alternatively you can also use a dedicated thread for this task and check if the system time is according to the values that you need. If values match execute your application.

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

It sounds like you need a service instead. Otherwise, your applicaton would only be running when someone was logged in. In it, set a timer for every minute. When the timer event fires, check through the list of scheduled jobs to see if any need to be started.

for check a checkbox you can use of GetCheck and its in another dialog you can use of

<br />
CMain *m_Main=(CMain*)GetParent(); <br />
m_Main->yourbutton.GetCheck();<br />

Do you know how to access member's of one dialog from another.
If yes,
You can assign a variable to the check box and then use GetState() to access the state whether checked/unchecked
If not,
You can pass a pointer of the first dialog in the second dialog and then do GetState();
You can use GetParent() also.

By using the GetCheck() method. It will return one of three "state" values.

Hello!

CString mfc_str = "Hello world";
char * c_str = (char *) (LPCTSTR) mfc_str;
LPCSTR c_str1 = (LPCSTR) mfc_str;

Wrong. Please don't suggest casts as the first solution, without knowing what they're doing.
From the question, you can tell that the program is being built for Unicode (otherwise CString would convert to LPCSTR automatically since LPCTSTR == LPCSTR in MBCS builds). In a Unicode build, casting LPCTSTR to char* will be disastrous.

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;

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.
