TextBox inheritance

I have defined a new class called "XtraTextBox" which inherits all properties from the class TextBox (built-in class), and have added some extra variables.

Later on I create an instance of this new class and populates it with property-values from an existing TextBox called "Hele". This new instance is called "UtipsHel", and I want to copy property values from the existing TextBox called "Hele" to this new instance of XtraTextBox.

"UtipsHel" should after this be a copy of "Hele", and in the end I make "Hele" invisible and "UtipsHel" visible. My goal is the replace "Hele" with "UtipsHel" on the form (Form1). But "UtipsHel" never shows up.

What have I done wrong here ?

(Visual Studio 2003 .NET).

XtraTextBox* UtipsHel = new XtraTextBox();
UtipsHel->Location = Hele->Location;
UtipsHel->BackColor = Color::FromArgb(255,255,0,0); // pure red
UtipsHel->ForeColor = Color::FromArgb(255,0,0,255); // pure blue 
UtipsHel->Enabled = Hele->Enabled;
UtipsHel->Font = Hele->Font;
UtipsHel->Size = Hele->Size;
UtipsHel->Text = Hele->Text;
UtipsHel->Text = S"RUBBISH";
__gc class XtraTextBox: public TextBox 
 int HeleMat;
 int HalveMat;
 int Sikre;
 int HeleUt;
 int HalveUt;
