Why did you delete your original question? I didn't see it, so now I have no idea what you are talking about.

1) Is there any way of determining/measuring the extent of the floating point part of my computation (as a % of runtime)?

2) Also, is there any way what to determine what currently dominates in my application - (I/O) or compute?

I guess what I need are some sort of monitoring functions?

Cheers

For 1.) Check out the PerformanceCounter class...you can set it to monitor the % of a method.

For 2.) I take it you want to find out what part of your application is most CPU intensive? If this is the case then check out in Visual Studio: (From the menu)

Tools->Performance Tools->Performance Wizard

This will get you started on getting statistics on all of your project's contained Methods.

Thank you.... I will check out the PerformanceCounter Class.

I can't find the performance wizard in the tools menu. Is this available in VS 2003?

A better idea. Get a profiler. This[^] is a fine example of one from RedGate.

Re: How to run a dos command from csharp application. [modified]

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");

Re: How to run a dos command from csharp application.

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,

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??????????

Give me an error with

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

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)
