Hi!
You'll have to subscribe to the (static) SessionEnding event of SystemEvents class and perform your operation in the corresponding event handler.

Thanks, I have tried hooking that event and I can start the process when I receive the event but I only have a limited time (very short) to respond before Windows displays a dialog saying the aplpication has not closed (the one with the progress ticking down and "End Now" button), this would not be acceptable. I was hoping there was a way to run a long operation after the user session has ended but before the machine has shut down, such as the offline files synchronisation process in Windows.

I don't know if there's a way to tell windows to postpone shutdown (perhaps there's a registry key for this), but right now I see only 2 alternatives:
1) Cancel the shutdown while your shutdown process is still running or
2) Start the shutdown process in a separate thread and don't cancel windows shutdown. But then your shutdown process can be aborted unexpectedly, so this might not be a good idea (depending on the real use case).

Are you displaying the subreports in a list?

Thanks carbon_golem,

No, i am not displaying subreports in a list.

I added subreport control from ReportItem toolBox to the main report.
I have created separate .rdlc file for the subreport and mapped with SubReport. Still the problem is not resolved.

Event without focus

Member 353710930-Mar-08 22:56

30-Mar-08 22:56

Hello,
I'll try to explain what I'm trying to do as sufficient as possible, or better I'll give an example. Usually when pressing F1 in an application we get help dialogbox. I want to do something like that. When I press F6 let's say I want to print. But I can't find a listener that does that. KeyDown only works when an object has focus. Does anyone know how to trigger an event when there is no focus. For instance, an MDiParent doesn't have focus when children are active, but I want to get the help dialog. Does anyone know how to do this? Thank you in advance.

You may add it to the key down event of the parent form itself

If you mean something like
this.KeyDown += System.Windows....
It doesn't work, because KeyDown works when the object has focus and it doesn't a Child does.

Re: Event without focus

Laddie30-Mar-08 23:45

this.KeyDown += new System.Windows.Forms.KeyEventHandler(this.Form1_KeyDown);

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
MessageBox.Show(e.KeyCode.ToString());
}

This works perfectly fine for me as long as the form is the active window.

Yes I know but the form isn't the active window

Then you have to make a hook to your keyboard events in the Os Level..

What about setting key preview?

If you set KeyPreview to true for your main form then use the key press event, it might get called even if your on a child window. You'd have to check though. It would be much easier than a global hook if it works.

Hi,

I appreciate any suggestions.

Thanks in adavance

You cannot directly associate the filewatcher with the data grid. What you may like to do would be add code to get the details of files in a data table in the events of Filewatcher and bind them to your data grid.

.NET is the Microsoft implementation of the CLI, so C#.NET implies the Microsoft implementation of the C# language.

However, if you are using something other than the Microsoft implementation, you should specify it, so unless you specify any other implementation, C# and C#.NET means the same thing.

Despite everything, the person most likely to be fooling you next is yourself.

Loosing Bytes in byte[][] while using WSE3 without MTOM

DanielWehrle30-Mar-08 21:50

30-Mar-08 21:50

Hello,

I wrote a little Server and run it under Win 2003 and Win 2008,

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1, EmitConformanceClaims = true)]
[WebService(Namespace="http://www.pyramid.de", Description="Pyramid")]
public class WormRaid : System.Web.Services.WebService
{
[WebMethod(MessageName="WriteBytes")]
public long WriteBytes (byte[][] memData)
{
return (memData[0].Length + memData[1].Length);
}
}

Now my problem is that the second byte array in a byte[][] is always received as 0 bytes, when the first byte[] length is a odd multiple of 1024 (1024, 3072 or ...). This error occurs only without MTOM, with MTOM everything works fine (see attached code).
The error is probably in the server side because the same error can be produced with a GSoap Client (also without MTOM).

Here my Client Code:

internal static int Main (string[] args)
{
long fsize1;
long fsize2;
long byteswritten;
byte[][] ba;
WormRaid wr;
Random rand = new Random();

try
{
fsize1 = 1024L;//only odd multiple of 1024 will not work
fsize2 = 512L;

Console.WriteLine(" (" + fsize1 + "), (" + fsize2 + ")\n");

// Create the data to send
ba = new byte[2][];
ba[0] = new byte[(int)fsize1];
rand.NextBytes(ba[0]);
ba[1] = new byte[(int)fsize2];
rand.NextBytes(ba[1]);

//Create Stub
wr = new WormRaid();
wr.Url = "http://localhost/WSE3Test/WSE3Test.asmx";

//First Test will work always
Console.WriteLine("WSE3 MTOM:");
wr.RequireMtom = true;
byteswritten = wr.WriteBytes(ba);

if (byteswritten != fsize1 + fsize2)
{
Console.WriteLine("!!! ERROR LENGTH !!!\nWritten: " + byteswritten + ", expected: " + (fsize1 + fsize2));
}
else
{
Console.WriteLine("OK\n");
}

//This test will fail
Console.WriteLine("WSE3 without MTOM:");
wr.RequireMtom = false;
byteswritten = wr.WriteBytes(ba);

if (byteswritten != fsize1 + fsize2)
{
Console.WriteLine("!!! ERROR LENGTH !!!\nWritten: " + byteswritten + ", expected: " + (fsize1 + fsize2));
}
else
{
Console.WriteLine("OK\n");
}

}
catch (Exception exc)
{
}
}

Sample output:
-------------------------------------------------
Y:\>Client.exe
(1024), (512)

WSE3 MTOM:
OK

WSE3 without MTOM:
!!! ERROR LENGTH !!!
Written: 1024, expected: 1536
-------------------------------------------------

Get anyone the same results?
Is there any known solution for this Problem?

Thank you,
