HI,
I've created a batch file called post-commit.bat and placed it under the /hooks directory.
The content of the file is:
TestCS.exe
The content of the exe file is:
static void Main(string[] args)
    {
        try
        {
            // create a writer and open the file
            TextWriter tw = new StreamWriter("date.txt");
            // write a line of text to the file
            tw.WriteLine(DateTime.Now);
            // close the stream
            tw.Close();
        }
        catch { }
    }
When I double-click on post-commit.bat, it creates the date.txt file.
When I commit in SVN, it takes time, and eventually gives me the following message:

What can be the problem?
Thanks!
