11-Oct-07 0:56

I have a csharp windows application, i am using Mysql database, i need to provide a utility from the application to backup and restore database.

I can run the following commands from the Dos shell, but i need to run the same from the csharp code. I used the folder browser and file dialog to get the path
and created the following string "mysqldump -u root -p XXXX emanage > c:\emanage.sql" . can some one help me out by telling how to run a command from csharp code.

Thanks in advance

To run a command in DOS generally

System.Diagnostics.Process.Start("cmd", "command comes here"); is used

The the above script just opens the dos console and does not run the command in the entered string. How do i run the command automatically.

Hey why don't u keep the required command in a batch (.bat) file and then run the batch file using..

System.Diagnostics.Process.Start(@"filename");

Thanks for the reply, i did a mistake earlier, i put cmd in the command string and actual command in the parameters, but now its resolved.

Thanks again.

string ls_path = @"c:\csharpbkp.sql";

System.Diagnostics.Process.Start("mysqldump", "-u root -p emanage >" + ls_path );

why does this not work,

Another Class:

class procesos {<br />
    {<br />
        struct sproceso<br />
        {<br />
            public int id;<br />
            public string NombreProceso;<br />
            public string DirProceso;<br />
            public string FileProceso;<br />
            public DateTime tiempoinicio;<br />
        }<br />
        ArrayList listaprocesos = new ArrayList();<br />
        bool existeproces = false;<br />
        bool coincide = false;<br />
        Timer nuevotiempo = new Timer();<br />
<br />
        public void iniciar(updatevalores procesoact)<br />
        {<br />
            <br />
            nuevotiempo.Elapsed += new ElapsedEventHandler(TiempoEjecutar);<br />
            nuevotiempo.Interval = 5000;<br />
            nuevotiempo.Enabled = true;<br />
        }<br />
<br />
}

The Line Thread pid = new Thread(new ThreadStart(proces.iniciar(new updatevalores(actualizarv)))); has give me an error.

How i can pass values to proces.iniciar method??????????
Thanks

    public delegate void updatevalores(int total);<br />
<br />
    public partial class FormConexiones : Form<br />
    {<br />
        private int procesosactuales = 0;<br />
        public FormConexiones()<br />
        {<br />
            InitializeComponent();<br />

            pid.Start(new updatevalores(actualizarv));<br />

        {<br />
            procesosactuales = total;<br />
        }<br />
    }

Give me an error with

ParameterizedThreadStart(proces.iniciar)
The error is: none overload correspond 'iniciar' match with 'System.Threading.ParameterizedThreadStart' delegate

what the Mad | :mad:

damn
i forget to read:

This is simple, but only accepts a single parameter and isn't type-safe (just like the options when using thread pool threads)

So you are fine with that?

All the best,

Patricio Tapia11-Oct-07 0:56

Yep
Works Fine:

procesos proces = new procesos();<br />
ThreadStart inipro = delegate { proces.iniciar(new updatevalores(actualizarv)); };<br />
new Thread(inipro).Start();

Ok, so much battle with Thread and asyncronic querys...

time to rest Sleepy | :zzz:

thanks for all Big Grin | :-D
