Your code will work fine if you just declare llError first:

LOCAL llError

llError = .F.

I do exactly this in my DB_EXCL function. If you want to compare code, you can download DB_EXCL from www.peisch.com/downloads.html.

ON ERROR llError = .T.

before I try to

LOCAL llError

My problem is, llError always is epual to .F. I found that ON ERROR will create llError as public and refer to it instead of my local llerror. Why?

However, once I call this function from form.method, form.error() will be fired everytime if USE failed. How could I force VFP to not use ON ERROR to handle error instead of FORM.error()?
