>It looks like SetFormat is reserved word. You shoul come up with another name for the method.

I solved the problem using SetFormat_() , no big deal. but I just want to add this info :

Other than that SetFormat is reserved word (which is true) but it seem that is not the only reason

If I used a procedure name ClearData() or or Setfocus() the parameter displayed by the intellisense is wrong.

While if I used Setup() or SetVar() which are also reserved word, the parameter displayed by the intellisense is correct.

There is something else effecting on the intellisense.
