Hi,
I need help with something I looking into but have been unable to retrieve directly. something like GET FILE DATE$(fileName$),
I know there is a possibility to do it with kernel32 functions, but I have been unable to do it.

The way I look forward to retrieve the file date, has to be different from GET FILE DATE$() function, since it has to go through many files because of FIND FIRST or FIND NEXT, and I need that the process is very fast since there can be many files and because of quick calling.

Thank you so much.

The get file date$() will work with multiple files in the fashion you stated, even the help text says so.

Hi Nomad.
Thanks.

As I said, that command is not useful to me because I have to go over every file to use the file I want. Since speed is a problem, what I really need is function that I can give as a parameter an absolute path and it returns to me the file date as any type (String for example).

Yes is possible,
but with the kernel32. I was not able, was very difficult for me to use the Kernel32. If someone can help me using it I will be very grateful.

I had a look at the MSDN about this problem, and if I'm honest it is much simpler to just use the native DBP commands.

Here is a simple function which returns the time and date of a filename given.

Hope it helps.

Hi Prof,
thank you so much for your interest.

when there are many files that way can become slow. Im trying to do a very fast solution to the problem, since speed is critical for it to work right with another things I'm doing.

Since kernel32 literally pulverized me, in this moment Im trying to do a c++ Dll that has a function that returns the last modified date, if you send the file full Path. I will post the results here so everybody knows the answer too.

Cheers.

AlfaX.

Hi all,
I have finished the dll, and want to share it with you all. It has only one function.

The difference with the DBPRO approach is that you only make one call to get the file date with is much faster than having to go file by file.

You can use it like:

hola$ = SDLL_getFileDate("c:\\test2\test.txt")

You can download the dll which I have attached to this post.
