      : base() {

    }

    public MyDictionary(SerializationInfo info, StreamingContext context)

      : base(info, context) {

    }

  }

}

The error I was getting was, "System.Runtime.Serialization.SerializationException: The constructor to deserialize an object of type 'MyNamespace.DataTypes.MyDictionary' was not found."

I got the idea here: http://www.vbforums.com/showthread.php?t=314430, which has the code example in VB.NET.

To serialize Dictionary objects using an XML serializer, you have to implement a custom dictionary as described here: http://weblogs.asp.net/pwelter34/archive/2006/05/03/444961.aspx.

The errors were of the type:

Warning: session_start() [function.session-start]: Cannot send session
cookie - headers already sent by...

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent...

One of those who reported the errors also provided a solution, which was to place the PHP session code before any of the html code. Perhaps the newer versions of PHP (I only have 5.1.1 installed) are getting more syntactically tighter. I know the newer versions of PHP are requiring full PHP tags now.

Anyway, there is a new version of the test.php code in my PHP install guide


' Builds a collection of all the ranges in this document.
' (StoryRanges, which include the headers and footers, augmented with any text box ranges)
' also include linked ranges via NextStoryRange to grab the odd page header/footers
Private Function AllRanges(Optional Doc As Document) As Collection
Dim Rng As Range
Dim Sh As Shape
Set AllRanges = New Collection
If Doc Is Nothing Then Set Doc = ActiveDocument
For Each Rng In Doc.StoryRanges
While Not Rng Is Nothing
AllRanges.Add Rng
Set Rng = Rng.NextStoryRange
Wend
Next Rng
' Grab all of the text boxes in the document, too.
' Use .ContainingRange to return the entire story that flows between linked text frames,
' but examine .Previous to make sure I grab it only once - from the first box in the chain.
For Each Sh In Doc.Shapes
With Sh.TextFrame
If .HasText And .Previous Is Nothing Then AllRanges.Add .ContainingRange
End With
Next Sh
End Function


Every Oracle Form is composed of Java objects. Text fields, buttons, frames, you name it, they are all some derivitive of Java awt or swing objects. As such, they can be extended.
Sounds simple, even too simple, doesn't it? Well, it really is!
If you're a Forms developer, there's a good chance that you know about embedding Java Beans (also called PJCs - Pluggable Java Components) into your Forms. They're really cool and can be used to accomplish all kinds of things. This takes PJCs one level further.

Anyway, here's one implementation I came up with. This text field extension underlines the text and does the following on mouseover: turns the cursor into a hand, makes the font bold, changes the font color to red, changes the background color to gray. You can easily add Property IDs to control the behavior. This concept and most of the code was taken from the Oracle demo ModCursor:


import java.awt.Graphics;
import java.awt.Color;
import java.awt.FontMetrics;
import java.awt.Font;
import oracle.forms.ui.VTextField;
import oracle.forms.properties.ID;
import oracle.forms.handler.IHandler;

public Hotlink()
{
super();
}

public void init(IHandler h)
{
super.init(h);

stdCursor = this.getCursor();

this.addMouseListener(new MouseAdapter()
{
public void mouseEntered(MouseEvent me)
{
if(getTextLength() > 0)
{
((VTextField)me.getSource()).setForeground(Color.red);
((VTextField)me.getSource()).setBackground(Color.lightGray);
setFont(stdFont.deriveFont(Font.BOLD));
setCursor(new Cursor(Cursor.HAND_CURSOR));
}
}
public void mouseExited(MouseEvent me)
{
if(getTextLength() > 0)
{
((VTextField)me.getSource()).setForeground(stdForeColor);
((VTextField)me.getSource()).setBackground(stdBackColor);
setFont(stdFont);
setCursor(stdCursor);
}
}
});
}

public void paint(Graphics g)
{
super.paint(g);
if (this.getTextLength() > 0)
{
FontMetrics metrics = getFontMetrics(getFont());
int strWidth = metrics.stringWidth(getText());
int yoffset = (int)(metrics.getHeight() * 0.95);
g.drawLine(0, yoffset, strWidth, yoffset);
}
}

public boolean setProperty(ID pid, Object value)
{
if(pid.getName().equals("FOREGROUND")) this.stdForeColor = (Color)value;
else if(pid.getName().equals("BACKGROUND")) this.stdBackColor = (Color)value;
else if(pid.getName().equals("FONT")) this.stdFont = (Font)value;
return super.setProperty(pid, value);
}
}
