>Hi, all! Please answer which function can determinate does object (in my sample form) exists or not. Thank you. Andrew

1. To check if an ListBox object exists in a form:

If Type("Thisform.ListBox1") = "O"
   ** existing
Else
   ** not existing 
Endif
<pre>

2. To check if a form is existing:
<pre>
IF WEXIST("NAMEOFMYWINDOW")
   ** existing
ELSE
   ** not existing
ENDIF

alternatively, you can also make use of Type("NAMEOFMYFORM") = "O".
