im working on my menu builder and ive stumbled across a problem, everything was working well until i tryed to add a combo box

this is the code to add some controls

Control := CDXUTStatic.Create(Dialog);
(Control as CDXUTStatic).SetLocation(SpinEdit1.Value, SpinEdit2.Value);
(Control as CDXUTStatic).SetSize(SpinEdit3.Value, SpinEdit4.Value);
(Control as CDXUTStatic).Text := StrToPWideChar(Edit1.Text);
(Control as CDXUTStatic).Default := CheckBox1.Checked;

Dialog.AddControl(Control as CDXUTStatic);
strType := 'Label';
Result := True;

Control := CDXUTButton.Create(Dialog);
(Control as CDXUTButton).SetLocation(SpinEdit1.Value, SpinEdit2.Value);
(Control as CDXUTButton).SetSize(SpinEdit3.Value, SpinEdit4.Value);
(Control as CDXUTButton).Text := StrToPWideChar(Edit1.Text);
(Control as CDXUTButton).Default := CheckBox1.Checked;

Dialog.AddControl(Control as CDXUTButton);
strType := 'Button';
Result := True;

(just to give you an example), that code works fine and the control (CDXUTControl) is added to the dialog fine.

however the following code doesnt work

Control := CDXUTComboBox.Create(Dialog);
(Control as CDXUTComboBox).SetLocation(SpinEdit1.Value, SpinEdit2.Value);
(Control as CDXUTComboBox).SetSize(SpinEdit3.Value, SpinEdit4.Value);
(Control as CDXUTComboBox).Default := CheckBox1.Checked;

for iLoop:=0 to Memo1.Lines.Count -1 do
(Control as CDXUTComboBox).AddItem(StrToPWideChar(Memo1.Lines[ iLoop]), nil);

Dialog.AddControl(Control as CDXUTComboBox);
strType := 'Combo Box';
Result := True;

the access violation is in UpdateRects on line pFontNode := DXUTGetGlobalDialogResourceManager.GetFontNode(m_E lements[2].iFont); (in the setlocation)

ive got, labels, buttons, check boxes, radio buttons working fine so far, this is the first one to crash.

any ideas?

Why are you not using "AddComboBox"?
Theoretically, just by exploring source code and waching for differences your implementation of "AddComboBox" lacks "Result := InitControl(pControl);"
