I'm surprised people actually suggested a hash table for this... wtf??? 
|
|
|
|
|
Yeah, the hash table threw me a bit, I've got this simple little App working thanks to all the advice given. The bit stumping me was transfering the 'results' onto the corresponding lables on the page.
Thanks though, this forum really works !

the c# code:
public delegate void SchedulerEventDelegate(SchedulerEventType type, string scheduleName);
static public event SchedulerEventDelegate OnSchedulerEvent;
if (OnSchedulerEvent != null)
how can I convert this to VB?
more detail:
I have a code in c# from http://www.codeproject.com/csharp/eventscheduler.asp
My boss ask me to convert it to vb.net
currently I have a problem with this line:
Code:
if (OnSchedulerEvent != null) (in c#)
when i convert it to
visual basic code:--------------------------------------------------------------------------------If Not OnSchedulerEvent Is Nothing Then--------------------------------------------------------------------------------
the error I'll get:
Public Shared Event OnSchedulerEvent(type As SchedulerEventType, StrScheduleName As String)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.
what can I'll do????
C# code
Code:
public delegate void SchedulerEventDelegate(SchedulerEventType type, string scheduleName);
static public event SchedulerEventDelegate OnSchedulerEvent;
if (OnSchedulerEvent != null)
Vb.net code
visual basic code:--------------------------------------------------------------------------------Public Delegate Sub SchedulerEventDelegate(ByVal type As SchedulerEventType, ByVal StrScheduleName As String)
Public Shared Event OnSchedulerEvent As SchedulerEventDelegate--------------------------------------------------------------------------------

I dont think you need to do the check in VB. The VB RaiseEvent Should take care of this for you.
All you need should be:
RaiseEvent OnSchedulerEvent(...)

|

thank but i'll did the convert and someting go worng at the vb.net
and i think the prublem is there

Here's a quick hint that will make your boss think you are a coding god.
First of all, download Lutz Roeder's excellent Reflector[^].
Then, open up the original DLL file that you want to redo.
Change the combo box from C# to Visual Basic and then select the methods you are interested in.
Select Disassembler and, hey presto, you have a VB.NET version of the C# code.

Yes, Yes!
There should be a "Lutz Roeder monument"!

(via Instant VB):
If Not OnSchedulerEventEvent Is Nothing Then
note the 'Event' tagged onto the end. This accesses the hidden <event>Event variable in VB. But as an earlier poster mentioned, you rarely should need to do this check in VB since "RaiseEvent" does it for you.

Hello
I want to send a crypted email with a certificate and a word attachment file.
So I have created a MailMessage and I have crypted my Word Document with my Certificate.
Then I have created and alternate View with the crypted attachment.
When I receive the mail, my mail is well cryped and the attachment is in the mail (icons are displayed in outlook)
The problem is that the attachment is opened in the body of the mail just like Text (So i can see all the word specific data).
I cannot see the word as an attachment and to save it.
Any Help is welcomed
<br />
MailMessage eMail = new MailMessage();<br />
eMail.From = new MailAddress("MyMail@MyCompany.com");<br />
eMail.To.Add(new MailAddress("MyMail@MyCompany.com"));<br />
eMail.Subject = "Test";<br />
SmtpClient Smtp = new SmtpClient("MyCompany.com")<br />
<br />
#region crypt<br />
<br />
X509Certificate2 myCertificat = new X509Certificate2(@".\MyCert.cer", "xxxx");<br />
System.IO.Stream myFile = null;<br />
myFile = new System.IO.FileStream(@".\Test.doc", System.IO.FileMode.Open,System.IO.FileAccess.Read);<br />
byte[] data = new byte[myFile.Length];<br />
myFile.Read(data, 0, (int)myFile.Length);<br />
<br />
ContentInfo contentInfoCrypt = new ContentInfo(data);<br />
EnvelopedCms envelopedCms = new EnvelopedCms(contentInfoCrypt);<br />
CmsRecipient recip1 = new CmsRecipient(myCertificat);<br />
envelopedCms.Encrypt(recip1);<br />
envelopedCms.Certificates.Add(myCertificat);<br />
byte[] encryptbytes = envelopedCms.Encode();<br />
#endregion<br />
<br />
MemoryStream mss = new MemoryStream(encryptbytes);<br />
<br />
AlternateView av = new AlternateView(mss, "application/x-pkcs7-mime; smime-type=enveloped-data; name=smime.p7m;");<br />
eMail.AlternateViews.Add(av);<br />
Smtp.Send(eMail);<br />

Hi All,
Is there any possiblity of getting the file name that is being closed currently.
For example, if a text file is opened by name "abc.txt". When I'm closing this file, a message must be prompted that "File abc.txt is closed". I need to do this in C#.
Any code sample will do..
Thanks in advance

Well, the normal way to do this is to store the filename in a member variable and then refer to this.

I'm not able to follow what the member variable means?
Could you be more specific?
Parimala
|
|
|
|
|
string memberVariable = filename;
|
|
|
|
|
Even if i get the filename, what event or action will indicate that the opened file is closed?

You could create your own class which handles all the file access, give it the member variable as suggested and create an event/delegate which you can fire when you close any FileStream. Then you can create an event handler in the main app to show your message.
Here's an article to help you create your own events if you've not done it before: http://www.codeproject.com/csharp/eventdelegates.asp[^]

How the text file is opened.. whether r u open it programmatically or juz like that u opened.
if you opend the file programmatically.. it is easy to notify that file is opened/closed otherwise c for any other possibility like FileWatcher class..
|

The file is opened programmatically. Another application has to monitor whether the file is closed or not.

I have written a console application for you:
<code>
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
namespace OnCloseEventExample
{
class SpecFileStream : System.IO.FileStream
{
private string _fileName;
public string FileName
{
get { return _fileName; }
set { _fileName = value; }
}
//lazy to create a new delegate. We are using System.EventHandler
public event EventHandler FileClose;
public SpecFileStream(string filePath, FileMode mode)
: base(filePath, mode)
{
_fileName = Path.GetFileName(filePath);
}
public override void Close()
{
FileClose(this, new EventArgs());
base.Close();
}
}
class Program
{
static void Main(string[] args)
{
string filePath = "";
if(args.Length < 1)
{
filePath = @"C:\test.txt";
}
else
{
filePath = args[0];
}
SpecFileStream sfs = new SpecFileStream(
filePath,
System.IO.FileMode.Create
);
sfs.FileClose += new EventHandler(sfs_FileClose);
byte[] data = Encoding.ASCII.GetBytes("writes to file this");
sfs.Write(data, 0, data.Length);
sfs.Close();
}
static void sfs_FileClose(object sender, EventArgs e)
{
SpecFileStream sfs = sender as SpecFileStream;
if (sfs != null)
{
Console.WriteLine("File " + sfs.FileName + " is being closed!");
}
else
{
throw new Exception("Invalid sender object class!");
}
}
}
}
</code>
If any comments are needed, feel free to ask.

When i'm compiling the code, i'm getting the following error. Could just tell me why this happens?
'System.IO.FileStream.FileStream()' is inaccessible due to its protection level

yes...!
it is posible but you have to get location where is your file is located. then using FSO object then you can get all files name of the directory.

Why the FileSystemObject? There are better .NET ways of doing this.

hpoe u can find ur way.....
