{
class Demo
{
// The entry point of the application
public static function Main()
{
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
$form = new TreeForm ;
Application::Run($form);
}
}

Thank you.

Hi,
the "ugly" compiler error message is caused by the "$this->GraphicsUnit->Point" expression. This is not correct, because GraphicsUnit is not a member of Form. It is a .NET enumeration, so you should use "FontStyle::Regular" instead.

Hope this helps!
Tomas

thanks for ur reply.

can you change below code to phalanger.

System.Windows.Forms.TreeNode treeNode3 = new System.Windows.Forms.TreeNode("Mssql Databases", new System.Windows.Forms.TreeNode[] {treeNode1, treeNode2 });


this.treeView.ClientSizeChanged += new System.EventHandler(this.treeView_ClientSizeChanged);
this.treeView.AfterSelect += new System.Windows.Forms.TreeViewEventHandler(this.treeView1_AfterSelect);

Hi,
you can get more examples in the "Deployment\Samples" directory of our latest source code. The "WinForms" example contains examples that might be very interesting for you :-).

To answer your questions -
// C#
new System.Windows.Forms.TreeNode("Mssql Databases", new System.Windows.Forms.TreeNode[] {treeNode1, treeNode2 });
// Phalanger
new System:::Windows:::Forms:::TreeNode("Mssql Databases", array(treeNode1, treeNode2));

// C#
this.treeView.ClientSizeChanged += new System.EventHandler(this.treeView_ClientSizeChanged);
// Phalanger
$this->treeView->ClientSizeChanged.Add(new System.EventHandler(array($this, "treeView_ClientSizeChanged")));

(but we're planning to include "+=" in the future too)

hai,
Now I have got all the tree nodes. Then I used
$this->treeView->AfterSelect( new EventHandler ( array ( $this, "treeView1_AfterSelect )) ) ;

function treeView1_AfterSelect()
{
.........
//printing some text message on the right of the form .
.. ........
}
-----or -----

$this->treeView->MouseClick( new EventHandler ( array ( $this, "treeView1_AfterSelect )) ) ;

function treeView1_AfterSelect()
{
.........
//printing some text message on the right of the form .
.. ........
}
This code works fine only at first time( when the programs runs ). If I will select any other nodes afterwords, text message is not changing.In .net this is not the case coz there is eventhandler. I need to check "nodeselection" everytime, can u give some idea for this...
Thanks for your reply...
