Objects methods

Hi,



I am new to testcomplete, when i am using .keys method for input textboxes. The method is working for some textboxes and not working for some textboxes. Here my doubt is .keys is the proper method for input to textboxes or is there any other methods.

   

             Please suggest me the best methods(.keys,.click) for different objects(textboxes,chechkboxes,radiobutton)



  Thanks in advance..
