I don't want to be rude here, but the assignment you're given, is a representation of your teachers expectations, and should be in line with what you've been taught and the source material you've been given. If you're totally lost, perhaps you deserve to fail, and try harder when you repeat the subject ? We're happy to help, but we don't want to short circuit a system that's designed to weed out people who are 'not good at programing' before we find ourselves having to work with them.
The task is pretty straightforward, talk to your fellow students, if you're all lost, then it's a problem with the teacher and you should take it to the people running the school. Otherwise, you should look at your notes, take the info you've been given, and try to do the work. If you show signs of having tried something and ask specific questions, we'd love to help further.

Not the way to do homework, but fair enough.

Well, putting the path to the image in an img tag seems the obvious way.

Hello,
It seems that the condition for errorprovider is not set properly. Let me give you a very simple
example where we will display an errorprovider for a Textbox when alphanumeric values are entered.
<br />
Private Sub TextBox1_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged<br />
<br />
Dim num As Integer = 0<br />
<br />
If Not TextBox1.Text.Equals("") Then<br />
<br />
If Not IsNumeric(TextBox1.Text) Then<br />
<br />
ErrorProvider1.SetError(TextBox1, "Please enter numeric value")<br />
<br />
Else<br />
<br />
ErrorProvider1.Dispose()<br />
<br />
End If<br />
<br />
End If<br />
<br />
End Sub<br />
I hope this helps. In case the issue persists, just provide the code where you have implmented the
errorprovider.
Regards,
Allen

hy everyone!
does anyone of you know how to get the correct encoding of a textfile?
because i do read the file via a streamreader and write a new one with streamwriter. but sometimes i do have problems with some signs.
i know the file was created on a unix machine (line seperators just \n instead of \r\n in windows etc.).
streamreader and streamwriter allow encoding to be used as a second/additional parameter when reading or writing of/to the file.
so my two questions:
1) which encoding do i have to use for unix textfiles so the characters are read and written correctly? (because here in europe we have characters like "ö" or "ä" but they are not displayed correctly during writing the file. in the original file they are displayed correctly. so i want to provide the encoding in the parameter, but there are so many. and i am not sure, if i choose one which seems to be working on one file, does this mean it works for every unix textfile?
2) is there a chance to get the encoding of the file, when reading it without knowing it from the beginning? meaning, i want to find out the encoding when i access the file and set it when reading it, some kind of "dynamic encoding setting".
thanks.
stephan.

and which encoding type do i have to use? because i read the msdn but it confused me more than it helped. tons of different encoding specifications and descriptions

Sorry, I really don't know. Something unicode based is what you're looking for though I think. Personally I would say stop using *nix, but then i'm sure you have a good reason not too (otherwise i'll bash your head in with a really big book  ).

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.

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);
}
