Does anyone know why the Clipboard will not work while it's nested within the iTunes event handler? I cannot figure this out for the life of me. Source noted code below.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using iTunesLib;
namespace WIKDSPK
{
public partial class Form1 : Form
{
private iTunesAppClass m_iTunes = new iTunesAppClass();
public Form1()
{
InitializeComponent();
try
{
m_iTunes.OnPlayerPlayEvent += new _IiTunesEvents_OnPlayerPlayEventEventHandler(m_iTunes_OnPlayerPlayEvent);
}
catch(COMException)
{
Application.Exit();
}
}
protected void m_iTunes_OnPlayerPlayEvent(object iTrack)
{
string iTArtist = ((IITTrack)iTrack).Artist;
string iTName = ((IITTrack)iTrack).Name;
string iTAlbum = ((IITTrack)iTrack).Album;
string m_iClipStr = "Now Playing [ Artist: " + iTArtist + " Name: " + iTName + " Album: " + iTAlbum + " ] www.wickedradio.org";
MessageBox.Show("THIS IS A TEST!"); //This works!
Clipboard.SetText("THIS IS A TEST!"); //This does nothing!
Clipboard.SetText(m_iClipStr); //This does nothing!
}
private void Form1_Load(object sender, EventArgs e)
{
Clipboard.SetText("THIS IS A TEST!"); //This works!
m_iTunes.Resume();
}
private void Form1_FormClosed(object sender, FormClosedEventArgs e)
{
m_iTunes.Quit();
}
}
}

This is not a framework bug. It is probably ITunes hijacking your clipboard. I have seen similar behaviour in Adobe Acrocrapread and VNC.

I know this is a simple question but I would like to know How and Why this works;
Lets say I have two forms : Form1 and Form2 where Form1 is the main form. I am creating a Form2 variable by clicking a button in Form1 as seen in the code piece below.
private void button1_Click(object sender, EventArgs e)
{
Form2 myForm2 = new Form2();
myForm2.Show();
}
Why am I able to see form2. Because myForm2 is a local variable and just after it is shown, the function button1_Click terminates. So I mustn't be able to see Form2.
NOTE-1 : If you try the same with MS VC++ you will not be able to see Form2.
NOTE-2 : I know in .NET variables are not deleted when they are out out of scope. Garbage collector does it. Bu in an other function I tried GC.Collect(); which forces the garbage collector but Form2 still remains, it is not deleted.
Regards

Hi,
a variable is visible ("in scope") as long as you are within the first pair of brackets {}
that encloses its declaration, so myForm2 lives only inside your button1_Click method.
The Form it refers to is an object, calling Show() makes it visible AND keeps it alive,
even when button1_Click returns and hence variable myForm2 fades away. Once visible, the Form
does not need the variable, it has its own life. You would have to close the Form somehow
(by clicking a Close box, or by calling the Close() method) to end its useful life and make it
collectable.

Thats the point; "Once visible, the Form does not need the variable". I just can't understand why and how?, sorry
But thats not the case in MS VC++. Once you create a dialog class and if the object is out of scope, the form is also deleted. Right?
There are strange things going behind c#

Oh no, if anything is strange it is in the C++ world.
A visible Form remains alive without a reference; same is true for a file you create on disk,
it does not get deleted when your file variable vanishes.
BTW dialogs get shown using ShowDialog() which does not return until the Dialog gets closed.

That's because the Form class is just a wrapper in the .Net runtime environment to manage a Windows API window handle. Creating a form and calling its Show method creates a window handle, and the window handle will remain until it is released (which happens when the form's Dispose method is called, be it from code or by Garbage Collecgtion). All these .Net classes handling windows API (or COM interop, which is even worse) have been designed to make life easy as long as you don't think about it too much. Soon as you start thinking it looks illogical and only reveals its logic when you read up on the System.Runtime.InteropServices namespace.
Being an old C hand you'll know much better than I what happens to window handles and things when they're not released. All I know is that when I detect a memory leak I have to look into the interop hell unless I can find an easy way (within .Net) to clean things up. That's twe price we pay for using a comfortable top level language like C# instead of ATL and MFC.

The variable contains a reference to the Form instance, a copy of that reference gets passed on to the Window Manager (or whatever), at which point your app and the whatever both refer to the instance, even when your reference is destroyed the whatever maintains its reference.

When ever you create a form and show it, a reference to the form is added internaly. There is a property of Application Object named "OpenForms" which returns a read only FormsCollection containing all the forms opened by the application. Since a reference is held to the form object even though your local variable is collected by gc, the form does not get collected. You can access the form through that collection and call the close method on it to close the form. Then the form is removed from the OpenForms collection and will be collected by the gc.

Thanks. I understand now; You can reach to the form by Application.OpenForms[1].
This makes sense

Try looking at the properties of the control.

I you mean to the left of the last row, it indicates that the user can add rows.
You can disallow the addition of rows with AllowUserToAddRows = false

I am using the AddInParameter to add a Int32 value as a SQL paramter. The problem I am having is that it is possible for this value to be null. When I try using logic to return either the int value or a DBNull value as the parameter, because the parameter type is DbType.Int32 I get a build error. How can I, based on the value of the insert integer, either add the actual int value or a DBNull value in the AddInParameter method?
Thanks,
Steve
