Wierd. If I complie the control to a dll and then add it to the toolbox via Choose Items it shows the icon.

hello, i wonder how it is possible to get hardware information using C#,net! e.g i want to access the thermal sensor of a graphic card , how is it possible ? ! and let me know if it is even possible under C#.net! i gave it a try and turned up with "Sensor class" in MSDN , but i dont know how to use it ,
another question is , as a matter of getting access to hardware infos, is C# limited compared to VC++?
i mean can i do those thing in C# that im capable of doing in vc++?/.. if yes what specifically can be done as hardware manipulating in C#?
tanx in advance

Member 4166824 wrote: thermal sensor
u can access the info only if the vendor has and gave the ability to Access
it, if not u'll need to try Assembly (
the thermal sensor is problematic
either way to Access hardware u can try The WMI way :

Good Day,
I'm working with the AES Decryptor (using RijndaelManaged), but when I try to initialize a byte[] array to store my ciphertext data, it throws an IndexOutOfRange exception.
using (FileStream Ciphertext = new FileStream(_InputPath, FileMode.Open, FileAccess.Read, FileShare.None))
{
using (FileStream PlainText = new FileStream(_OutputPath, FileMode.Create, FileAccess.Write, FileShare.None))
{
using (CryptoStream CStreamWriter = new CryptoStream(PlainText, Decryptor, CryptoStreamMode.Write))
{
byte[] CTextData = new byte[Ciphertext.Length];
The exact error message is: "Index was outside the bounds of the array."
The weird thing is, this only happens for file > 200MB. But for a 150mb file, I have no problem.
Please advice thanks!

Perhaps because the system is unable to allocate an array that large.
Don't read the entire file at once, there is no reason to have all the data in memory at the same time. Create a buffer and read only a small part of the file each time.

ihave a asp.net page having some textboxes and dropdownlists , and one checkbox ,
i want that when i check checkbox and click the sibmit button then this data of the page should be redirect to next page but with the checkbox to be transfered as checked and readonly. and also i have three textboxes whose values are taken froma datebox which i created from javasript. so i want this date value also to be transfered to the next page. the next page is of data updation so in the next page all this value will be send and when in that next page i can click update button and then i will get be redirect or get a update success message on the same or another page .

2nd page name is secound_page
database table name is enf_data
please tell me how to do all this.

Well, this one has me stumped.
VS2008 Targetting .NET 3.5 (error also occurs when targetting .NET 2.0)
Given the following code:
private void OnBrowse(object sender, EventArgs e)
{
var fd = new OpenFileDialog
{
Filter = "Image Files(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|All files (*.*)|*.*",
Multiselect = false
};
if (fd.ShowDialog() == DialogResult.OK)
pictureBox1.Load(fd.FileName);
}
in a very simple WinForms app. The code loads and displays an image in the picture box control. So I know that part is working.
The following code:
private void OnSave(object sender, EventArgs e)
{
try
{
pictureBox1.Image.Save(@"c:\src\test\image.bmp", ImageFormat.Bmp);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
throws an 'A generic error occurred in GDI+' exception. The image file loaded in the OnBrowse handler is not the same image file I'm trying to save to. The target directory has read and write permissions. The output file is created when I run the program but has a length of zero bytes.
I've searched Google and all the solutions indicate a permissions error, which would make sense if the file isn't even created but, as it is created, I can't see it being a permission problem.
Any hints would be gratefully received.

Hi,
this is my standard advice on Image.Save problems:
Most, if not all, errors inside GDI+ are reported as "generic problem occurred in
GDI+". If the affected line is an Image.Save chances are your path is incorrect or
inaccessible, your disk is full, or your destination file exists and is locked.
if you load an image from a file, most of the time the file remains locked as long as
the Image is alive. This would prevent you from saving an image to the same path.
It applies to Image.FromFile, and probably also to PictureBox.ImageLocation
The one exception I am aware of is when you use Image.FromStream
An alternative work-around is to work with a copy of the image:
load the image with Image.FromFile,
create a new image from it with new Bitmap(Image),
dispose of the original image.
Hope this helps.

Thanks for the advice Luc. Obviously the image in the pictureBox is locked because I changed the code to load the image into a new Bitmap object and save from there and it's now working.

I'm sure there's lots out there. Maybe you folks have your favorites?

Have one, but in C++. Would have to go dig it up. Also have a good one for Hamiltonian Cycles, again in C++.

I need just a simple console program to tell how many days and hours (minutes if possible) until this persons next birthday.
He was born on July 26th 1983 at 8:00 pm.
I'm really new at this and I wanted to give him a small exe (console program) for his birthday.
This is all I oould come up with so far:
using System;
class myApp
{
public static void Main()
{
DateTime CurrTime = DateTime.Now;
DateTime JimBDay = DateTime.Compare(CurrTime, "08/01/2008");
Console.WriteLine("Jim's Birthdate: ", JimBDay);
Console.WriteLine("Jim's Birthday is July 26th at 8:00 pm");
Console.WriteLine("{0:F}", CurrTime);
// Need some code to say there are this many days and this many hours until your next birthday (minutes if possible).
Console.Read(); // wait
}
}
|

you can use subtract Method to get days and hours and minutes and seconds difference between two date.
see this code:
DateTime CurrTime = DateTime.Now;
DateTime JimBDay = new DateTime(1983,7,26,20,0,0);
TimeSpan span= CurrTime.Subtract(JimBDay);
now span has days and hours and minutes and seconds difference between jim birthday and now.

JimBDay does not show up on Console.WriteLine("Jim's Birthdate is... ", JimBDay); it just says "Jim's Birthday is..."
and
"span" shows as 9132.03:46:30.4287493 / How can I format this to say...
This many months...
This many days...
This many hours...
and
This many minuts until your next birthday?
using System;
class myApp
{
public static void Main()
{
DateTime CurrTime = DateTime.Now;
Console.WriteLine("Right now the date and time are: {0:F}", CurrTime);
DateTime JimBDay = new DateTime(1983, 7, 26, 20, 0, 0);
Console.WriteLine("Jim's Birthdate is... ", JimBDay);
TimeSpan span = CurrTime.Subtract(JimBDay);
Console.WriteLine(span);
Console.Read();
}
}

You'll have to pick apart the pieces from the span. There's Days, Minutes, and other properties to investigate.

try these properties:
Console.WriteLine(span.Days.ToString());
Console.WriteLine(span.Hours.ToString());
Console.WriteLine(span.Minutes.ToString());
Console.WriteLine(span.Seconds.ToString());
Console.WriteLine(span.Milliseconds.ToString());

First you need to find the next birthday. Create a DateTime value for the birthday this year (from the current year and the month and day from the birthday). If it has passed, add a year to the value.
Now you just subtract the current date from the value, and you get a TimeSpan that holds the time difference.
Despite everything, the person most likely to be fooling you next is yourself.

Please clean up your question. It really makes no sense and is confusing
