Control not declared?

[hness1]

Hello!

I have a little project of my own to convert a memory game puzzle from VB.Net into Delphi (Not a big Delphi fan). I was doing fine so far until a control would not be recognized (outlined in red and green). It is an imagelist containing 8 images.

1. Why is the control not being recognized?
2. How would I reference and image from the imagelist?
3. Can an array have a property (Outlined in green)?

I am using Lazarus Delphi/Pascal?

Thanks for any help. It is the memory game where you pick 2 cards from a grid of cards to match them.

And yes, the imagelist is called 'pictures' (thats what the (name) property has in it anyway)

Examine carefully classes. You invented the wheel.
Note the two properties have TForm1 - Controls [], and Components []. Number of them ControlsCount and ComponentsCount.
You put in design time 32 TImage component on TForm1. Hence Form1 already contains an array of pointers. Likewise, instead of TForm could be such TPanel.
See your TImage can be as follows:
for i: = 0 to Form1.ComponentsCount-1 do
if (Form1.Component isTImage) then
(Form1.Component as TImage). Picture.Assign (...);
