How to read a Label/Text box on a separate program

Hello

I need to read a Label/Textbox on another program. I can get the handle to the window containing the Label/Textbox using FindWindowLike API and SPY++ but can't get a reference to the actual Label/Textbox. Do these controls have handles and if so how do you find them? I am wanting to get the Label/Textbox's caption/text, forecolour properties etc.

thanks for your help
