Sorry - I use a server instance name but I'm pretty sure you can use a bracketed IP address [###.###.###.###]

Hi,
I'm using C#.net 3.0.I used this code but it is still showing an error highlighting fThread.Interrupt() ---Object reference not set to an instance of an object.Now what changes should I do in order to make this code work
[code]
private void frameExtract()//function to extract frames
{
string outPath = txtExtBitmap.Text;
System.IO.Directory.CreateDirectory(outPath);
if (fg != null)
{
foreach (FrameGrabber.Frame f in fg)
{
using (f)
{
picBoxFrame.Image = (Bitmap)f.Image.Clone();
f.Image.Save(System.IO.Path.Combine(outPath, "frame" + f.FrameIndex + ".bmp"), System.Drawing.Imaging.ImageFormat.Bmp);
Application.DoEvents();
}
if (fg == null)
{
return;
}
}
}
}
public void ThreadProc()
{
try
{
MethodInvoker mi = new MethodInvoker(this.frameExtract);
this.BeginInvoke(mi);
}
catch (ThreadInterruptedException e)
{
Console.WriteLine("Interruption",e);
}
catch (Exception we)
{
Console.WriteLine("Exceptiom",we);
}
}
private void button43_Click(object sender, EventArgs e)//Extract button
{
fThread = new Thread(new ThreadStart(ThreadProc));
fThread.IsBackground = true;
fThread.Start();
}
private void button44_Click(object sender, EventArgs e)//Stop Button
{
fThread.Interrupt();
fThread = null;
}
[\code]

The error is telling you that fThread was not created. Make sure that it has been created and is not null when you click button 44.
Why is common sense not common?

What do you mean by this code? Interrupting a thread and setting it as NULL doesn't make any sense. Also do a NULL checking before you use the thread object.

hi,
thanks for your reply.I'm not able to figure out this problem since I have already created the fThread in button43 click event and also instantiated it.

Hi,
I have a firebird database and because of an update to a single table i need to make some calculations ( alot of calculations, I cant do them in a stored procedure(in firebird) because some of required information is in sql server, so the functionality would be added using C#). I think triggers might help, but is there any way in which a firebird trigger would call C# code. What if i make a windows service in C# and somehow make firebird trigger run the service. If anybody has any idea, please provide help.
thanx for helping.

Who is updating this table? C# code? If yes, do all the calculation in the C# code only after updating the table. A trigger can't call a C# code.

|
|
|
|
Hi, thanx for your reply.
The table is being updated by another application. My C# application has access to the database only, hence i talked about using a trigger (at database end). Without a trigger, how would i know whether code is updated or not.

Triggers are EVIL - find a better solution, as Navaneeth suggested

Hi,
Thanx.
I think i have no other option.
An application (not mine) makes a change to the database, after this update my application should make changes accordingly. how do i know when an update to table has been made and carry out tasks that i desire.

Understood - a trigger is the solution to the problem. However all you need the trigger to do is send some info to your application. You want the trigger to be as stupid as possible to simplify the process (and keep support easier). I would devise a way for the trigger to communicate with your app. Set a flag in a table you own and can monitor, call a web service that can do your processing, send an email (I don't beleive I am said that).
SQL can't interact directly with your client but it can communicate so check out the different methods. I like the flagged table but if time is critical I would use a web service, which SQL can call, to do the notification.

Hello,
So what I want to do basically is this:
The user opens the client Console Application, and connects to the server Application on the server. It prompts a user for a username/ password. Once they hit enter, it sends the request to the server and it checks to see if those details exist or not. If it is succesful it will prompt the user that their login info is correct, and it opens Form1. If it is incorrect, it will bring back an error message and log the IP on the server..
What kind of system should I do for this, are there any tools like this out there? Please help me.

Are you asking how client and server communication can be done? If yes, you can use WCF/Web services or normal TCP communication.
|
|
|
|

I don't want to do this through web application. How can I do this through TCP communication? Lead me in the right direction.

Start from the TCPListener[^] class. But I suggest you to take a look at web services or WCF which makes the communication simple.
|

Do you know of any TCP clients/ servers that are functional to suite my needs. I only have a about a day before this needs to be deployed.

You need to speficify, code, test and deploy a complete client server authorisation suite in less than a day?

hello
[sorry about long trace thought it may help]
I ran into this remoting permission problem after signing my dll's, any idea why signing has anything to do with this please? (I confirmed this has to do with signing because I restore my last good backup, then sign my util dll's and rerun test cases, which gives me this)

i'm thinking perhaps it has to do with StrongNameIdentityPermission - but seems like un-signed code is granted to make call to deserialize sent data, while signed code failed. That's very counterintuitive.
But really I'm suspecting something like this in "System.Runtime.Remoting.Channels.ServerProcessing.ProcessMessage"
<br />
StrongNamePublicKeyBlob publickeyblob = new StrongNamePublicKeyBlob (publickey); <br />
System.Version ver = new Version(version); <br />
StrongNameIdentityPermission sip = new StrongNameIdentityPermission(publickeyblob,strongname,ver);<br />
sip.Demand();<br />
But then looking at error where failure occured: System.Security.Permissions.SecurityPermission
(With Permission Flag = SerializationFormatter)
How can I check if my user account (which is local machine Administrator !!) has SerializationFormatter permission? Or most importantly, how can I grant such permission?
In fact I checked by (run under same user account), and the user *indeed* has the permission (i.e. no SecurityException thrown in below code):
<br />
System.Security.Permissions.SecurityPermission oSecPerm = new System.Security.Permissions.SecurityPermission( System.Security.Permissions.SecurityPermissionFlag.SerializationFormatter);<br />
try<br />
{<br />
oSecPerm.Demand();<br />
<br />
Console.WriteLine("Operation permitted!1");<br />
}<br />
catch (System.Security.SecurityException ex)<br />
{<br />
Console.WriteLine("Operation not permitted!!");<br />
}<br />
I also used caspol -resolvegroup to check which code group it belongs (RemotingInterfaceInteractiveClient.exe and Util.dll - both shows it belongs to groups with Full trust all all policy levels)
I further confirmed this by: caspol -security off
Then watch test cases failed even after caspol is OFF!?
Help needed, really confused.
