is there any method to get items in "applications tab" in "windows task manager"

I don't know if the BCL provides a method to do so, but the EnumWindows API funcion provides that functionality. The idea is only to enumerate the visible top level windows.
You can call this routine in C# through P/Invoke.

I need an example about how can I view an jpg image file and write it into a file in C#.net.
Especially if I want to download jpg from an internet url by http.
Or how can I create a bitmap or image object directly from the url adress, I tried stream objects but couldn't manage it. If it is not possible, how can I save an image file from a http url? then I can use it to create bitmap object. Please give an example code...

I am trying to send email using the simple mapi. I cannot download the example because the server seems to be unavailable, so I wonder if anyone can help.
The problem I have is how to handle the MapiRecipDesc field in the MapiMessage structure. Apart from this it all works except I can't fill the Address field. I have the following declarations
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Ansi)]
public class MapiMessage
{
public uint ulReserved=0;
public string lpszSubject="";
public string lpszNoteText="";
public string lpszMessageType="";
public string lpszDateReceived="";
public string lpszConversationID="";
public uint flFlags=0;
public MapiRecipDesc lpOriginator;
public long nRecipCount;
public MapiRecipDesc lpRecips;
public ulong nFileCount=0;
public MapiFileDesc lpFiles;
}
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Ansi)]
public class MapiRecipDesc
{
public ulong ulReserved=0;
public ulong ulRecipClass=0;
public string lpszName="";
public String lpszAddress="";
public ulong ulEIDSize=0;
public IntPtr lpEntryID = IntPtr.Zero;
}
and in the body I do
public const uint MAPI_TO=1;
MapiMessage message= new MapiMessage();
MapiRecipDesc recipDesc =new MapiRecipDesc();
recipDesc.ulRecipClass = MAPI_TO;
recipDesc.lpszName = "Fred";
recipDesc.lpszAddress = "someone@somewhere"
message.lpszSubject = "test subject";
message.lpszNoteText = "test message";
message.nRecipCount = 1;
message.lpRecips = recipDesc;

Hi I’m going to decrypt a string that my supplier is going to send to my aspx-page.
I’ve got the key to use when I decrypt using Rijndaels algorithm.
I think I should use the System.Security.Cryptography.RijndaelManaged class but have problem setting the Key property.
Here Is my code:<br />
<br />
RijndaelManaged myRijndael = new RijndaelManaged();<br />
byte[] key;<br />
char[] base64CharArray = new char[16];<br />
base64CharArray = "1234567890123456".ToCharArray();
<br />
string base64String = new string(base64CharArray);<br />
<br />
key = Convert.FromBase64String(base64String);
I got the following runtime error:
An unhandled exception of type 'System.FormatException' occurred in CryptoDev.exe
Additional information: Invalid character in a Base-64 string.

hi 
now am going to have a traffic network map from autoCad , its now well understood as lines,circles,curves (shapes and only shapes) , i want to identify the street , intersection , square so that i may apply my calculations on it due to entered data on those elements ( street,square,intersection ) .
the problem is turning lines and curves into traffic elements .
i had an idea too , am not going to enter the network from autoCad but i will build my own drawing tool in the program so elements identification is solved in that way .
want your opinions .
thanks alot .

I think you need to look at GIS (Geographical Information System) software rather than AutoCAD. AutoCAD is really not designed to handle geographic information (even although some people insist on using it for the purpose).
I would recommend that you look at products by ESRI, MapInfo, or if you have an especially large project, Smallworld (Now part of GENS - General Electric Network Solutions)
Do you want to know more?

There are actually several articles here in CP that cover this topic specifically. I would suggest here[^].

Very possible, but very difficult.
Its a fun thing to do  However, for a company its not worth the effort. U can save some money (time = money) if you buy a finished grid solution.

Hi,
I use ProgressBar and Label for Copy files from a directory to different directory to display status of progress. ProgressBar to display progress and Label to display current file number of progress.
But while procedure Copy running then Lable don't update it's values, when procedure Copy finish only then Lable update last it's value.
I used Refresh method of Label but procedure Copy terminated when I move main Windown.
My code:
private void Copy_File()
{
string SourceDir = "C:\\Source", DesDir = "C:\\Destination";
string[] sFileArr = System.IO.Directory.GetFiles(SourceDir);
string sSourceFile, sDesFile;
if (sFileArr.Length>0)
{
this.progressBar.Minimum = 0;
this.progressBar.Maximum = sFileArr.Length;
for(long iFile = 0; iFile < sFileArr.Length; iFile++)
{
sSourceFile = sFileArr[iFile];
sDesFile = DesDir + "\\" + System.IO.Path.GetFileName(sSourceFile);
this.Lable.Text = iFile.ToString();
this.progressBar.Value = iFile;
this.Lable.Refesh();
System.IO.File.Copy(sSourceFile, sDesFile, true);
}
}
}
Thanks,

Take a look at Application.DoEvents()[^].
You can also try doing what you are doing on a different thread and use Control.Invoke() to call back to the UI thread to do updates.

Have you even tried simple intellisense search?
Very simple: DateTime. Specifically System.DateTime. For detailed information visit: MSDN[^]
