Hi,
try new Encoding(codepage) where codepage probably is 1252.
There is no general way of detecting the encoding; if it is Unicode/UTF8 you
will find two special leading bytes; if it is an 8-bit ASCII extension (as I
expect it is for you), you won't get a clue: every codepage is another way
to map the top 128 byte values to a immense collection of possible characters.

Hello everyone,
When we call Environment.Exit to terminates a console application or a Windows service,
1.
All the expected finally blocks are ensured to be executed, so resource leak?
2.
No exception occured (i.e. when invoking Environment.Exit, no exception thrown, like invoking Thread.Abort will throw ThreadAbortException?)
thanks in advance,
George

No, managed threads will be suspended and then terminated, so the CLR does not make any explicit attempt to execute finally blocks. It does execute finalizers though. And your process is going down, so the OS is going to cleanup all process local resources anyway.

No again - it doesn't throw any exception as part of normal execution.

Can any one tell me how to extract Excel worksheet images and store them in database?
Thanks in advance.

Did you even try searching codeproject before asking this?

Loading an excel spreadsheet is trivial, as is putting the data into a database.

Did you read my question carefully before you reply?!!
I'm trying to read All images in an Excel file (not the spread sheet data)
and store these images in database.
Please don't reply if you have no idea.

I though 1 Kelvin == 1 Celsius? Whats the /10 for?
You should also check what decimal.Parse actually returns, to make sure that parts working correctly.

Yeah, so 1K = 1°C

Hi Thomas,
Thanks for your help,but I dont really understand it. I am just a beginner.
This code works properbly
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Management;
namespace GetCpuTemp
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ManagementClass processClass = new ManagementClass(@"root\WMI:MSAcpi_ThermalZoneTemperature");
foreach (ManagementObject service in processClass.GetInstances())
{
MessageBox.Show("CPU Temperature: " + service.GetPropertyValue("CurrentTemperature"));
}
}
The messagebox show me a temp. of 3012 kelvin and my problem now is, that I like to convert it to celcius and read it out on a messagebox. Can you please help me, because I dont know how to do it. I tryed this code, but I dont know how to get it out in a massegebox.
static decimal ConvertToCelsius(string reading)
{
return (decimal.Parse(reading) / 10 - 273.15m);
}

Really ? In that case, you are definately very much a beginner. You should buy a very basic C# book and work through it, instead of relying on these forums, you're not really ready to make this your main source of information.
Never call decimal.Parse, use TryParse so your code never blows up.
Two clues:
1 - every object in C# has a tostring method
2 - if you concatenate anything to a string, C# calls that for you, for free.

All,
I have a requirement to find out where a particular process was started from (c:\somepath for example).
The system.diagnostics namespace doesnt appear to have this info, does anyone have any ideas?
Thanks,
|
|

|

It does have the info, but its a little hidden. What you need to look at is Process.MainModule.FileName.
So this would show you the paths for all the currently running processes:
foreach(Process proc in Process.GetProcesses())
{
MessageBox.Show(proc.MainModule.FileName);
}

Hello everyone,
I am new to this API. After some study, Application.Exit should only be used in Forms application, and in console/Windows service application without any GUI Window, we should not use it to exit application, right?
thanks in advance,
George
|
|
|
|
|
|
Cool, Urs!
I think the answer is, in console and Windows service application, Aplication.Exit has no use and it is not used to cause process to terminate, right?
regards,
George

Application.Exit will never terminate the process.
Normally you have something like this in your winforms app:
public void Main()
{
MyForm form = new MyForm();
Application.Run(form);
}
Application.Exit will cause that the Application.Run method returns to the Main method and then, of course, the process will end, because nothing is done afterwards.
best regards
Urs

Thanks Urs,
So, for console application and Windows service application without GUI, Application.Exit is useless, right?
regards,
George

If there is no Application.Run process running, then the Application.Exit function is useless.
As far as i'm aware your statement is true.
Cheers,

Cool, Mark!

Hi George,
A lot of applications don't need Application.Exit(), even Windows Forms applications
can do without if one wants them to only terminate when the main form gets closed.
Service means no forms, means no Application.Exit().
I trust you are aware of Environment.Exit()?

Yes, Luc! Currently, I am using Environment.Exit (-1). And I want to keep on learning new things. Is Environment.Exit safe that no resource leak will occur (and all expected exception handler and finally blocks are executed)?

George
