Invalid cast in code but not in command window

[Andrew]

Hi,

I am doing some code which involves type conversion and have run into a
problem I find odd.

I have a control of type class1 in a referenced assembly called
subclassedcontrols.
The line below used to work in other code, Facet is a property of my class1
control which inherits from a normal textbox
MessageBox.Show(CType(ctl, SubClassedControls.Class1).Facet & ctl.Text)

Exception message is:

An unhandled exception of type 'System.InvalidCastException' occurred in
VisualNotepad.exe

Additional information: Specified cast is not valid.

BUT this line executes OK in the command window

?CType(ctl, SubClassedControls.Class1).Facet & ctl.Text

Any pointers? I cannot understand why it should work in the command window
but not in the code running

Best regards,

Andrew

Is Facet a string? Perhaps the MessageBox is expecting a string and cannot
cast Facet to a string. If it is descended from a textbox, perhaps you
could use Facet.Text
MessageBox.Show(CType(ctl, SubClassedControls.Class1).Facet & ctl.Text)

BUT this line executes OK in the command window

?CType(ctl, SubClassedControls.Class1).Facet & ctl.Text

The two lines are not strictly the same. One uses MessageBox. Perhaps
there is something about using messageBox that is causing the problems.

Good luck.
