iTextSharp is a free .NET PDF extension. But even with it, writing pdf files in .NET is not very easy. There are some articles here on CP about iTextSharp, and also other free libraries, but most of them with limited functionality.

Search the "Articles" section.

You can't use flash to create web pages. When you create a "web page" in flash, it's just a flash movie that you show as an embedded element in a web page.

Hai Everybody,
I want to queue some events in the message queue and it has to be retained even though the system is restarted. I have created a message queue as follows but it is not retaining the messages can any one give a solution to this please it is very very important and urgent.

<br />
                    private System.Messaging.MessageQueue eventMessageQueue;<br />
                    if (!System.Messaging.MessageQueue.Exists(System.Net.Dns.GetHostName() + @"\EM"))<br />
                    {<br />
                        try<br />
                        {<br />
                            eventMessageQueue = System.Messaging.MessageQueue.Create(System.Net.Dns.GetHostName() + @"\EM",true);<br />
                        }<br />
                        catch (System.Messaging.MessageQueueException messagingException)<br />
                        {<br />
                            schedulerClass.LogError(messagingException, "Scheduler Error", EventLogEntryType.Error);<br />
                        }<br />
                        catch (Exception generalException)<br />
                        {<br />
                            schedulerClass.LogError(generalException, "Scheduler Error", EventLogEntryType.Error);<br />
                        }<br />
                    }<br />
                    else<br />
                    {<br />
                        eventMessageQueue = new MessageQueue(System.Net.Dns.GetHostName() + @"\EM");<br />

Hi all
I cannot match between thread and process. Need to kill a cirtain thread, I know in general to what module the thread belongs but cannot distinct between the diffrent threads. all I get is a list of the threads ID that belong to my process....

Killing a thread is a bad idea in almost all cases. It can destabilise the entire process.

No I dont think so.

AFAIK the managed threads are virtual, i.e. they are not even guaranteed to correspond to
a physical (i.e. a Windows kernel) thread.

This is somewhat illustrated by the fact that managed threads have a ManagedThreadId property,
whose value does not correspond to the kernel's thread IDs; and it has a name, for which
the kernel has no equivalent member at all.

In my experience, there still is a 1-to-1 correspondence between a managed thread and a
kernel thread, but I havent found any way to map them, other than having each managed thread
call some native code to get its own kernel thread ID that is.

Hope this clarifies things a bit.

Do you want to include Dialog box which are created in VC++ ? Is it anything like MFC COM (ActiveX) controls ?

No,
May it be created in C# and generated by the wizard as C# Form is.
Hope this clarifies.
Thanks.

using settings

Hi,
I created a settings file using Visual Studio 2005. The class for the settings file is generated as internal by VS. I need to reach it from another namespace so I want to make it public not internal. Is it good to make a settings file public or does it have any bad effects?

Re: using settings

Guffa22-Jul-07 22:39

As it is internal, it's available in the entire assembly, even from a different namespace.

If you need to use the information in another project in the solution, you get a mutual dependency if you access the settings directly. Instead you should send the needed information when calling the method, or creating the object instance, that needs it.

I believe the cs file in question is machine generated so its no point making changes to that. Why dont you write your own class which can traverse the settings file using the XML namespace.

Hello,

In your CancelButton code (Click event handler), you could set the DialogResult property of the Form to DialogResult.Cancel.
So if the user Closes the Form over the 'X', the Default would be DialogResult.None.

private void CancelButton_Click(object sender, System.EventArgs e)
{
    this.DialogResult = DialogResult.Cancel;
    this.Close();
}

protected override void OnClosing(CancelEventArgs e)
{
    if(this.DialogResult == DialogResult.None)
    {
        //Comes from X
    }
    else if(this.DialogResult == DialogResult.Cancel)
    {
        //Comes from CancelButton
    }

    base.OnClosing (e);
}

Hope it helps!

All the best,

Martin
