Class TSpinEdit not found

[Tom Crone 0]

I'm using Delphi 11.3 CE. I get a EClassNotFound error TSpinEdit not found.

I assume I need to add something to my uses statement? I tried VCL.samples.spin (that's were the help file says TSpinEdit is).

When I tried Lazarus and got a TButton not found, I wasn't surprised, but ...

Is TSpinEdit present on the Component Palette?  Is the "Embarcadero Sample Components" package ($(BDS)\bin\dclsmp280.bpl) installed in the IDE in the "Component | Install Packages..." dialog?

That is the correct unit.

There is a Samples entry in the same 'bar' as 'Standard', 'System", 'Dialogs', etc. and it shows TSpinEdit; that is where I got it to put on  my form.

 

I just deleted the TSpinEdit from the form and replaced it; it then gave a TSaveDialog not found, so I deleted and replaced that too.

 

It now complies.

 

Any idea why?

Your project was likely missing the relevant package references. Recreating the components updated the project.

Thank you!

 

I don't understand why replacing the controls got the package references, when placing them the first time didn't,

but now I know something to try.
