See faq #7557.

>My seccond problem is that i use the upper() in one form. When the form runs inside VFPro environment the function worKs corectlly, but, when the form is opened via an .exe the funtion does not work.

Can you be more specific? Does it generate an error? Where on the form are you using it? Can you post relevant code?

BTW, it's better to create separate threads for unrelated questions.
