I figured out what's wrong: I need to "wrap" the form in a component derived from TComponent. Then, I added a Execute function to the form to set all the properties I needed.

Question
Custom Component based on TCustomForm
Hello,
I'm trying to make a component that is basically just a form with a label and a timer. I'm trying to make it into a component that I can drop onto other forms. My problem is this:
When I drop the component onto a form, it shows the whole form that the component's based on. I need it to just show a standard-size bmp (like most components do) that I can click on and set properties, etc.
Any ideas on what I'm doing wrong? (This is my first foray into writing components).
Thanks!

Hi,
Use another ancestor to derive your component from, depending on:
- if your component should receive focus - TCustomControl, TWinControl (TCustomPanel migth be also appropriate in your case - create the label and the timer in the constructor). You may also prepare corresponding published properties and events for them on a component level - like Caption, Interval and OnTimer.
- you may use TGraphicControl for components that don't need to have a handle and don't need to receive input focus.
Regards, Geo
