Im using “IsNull()” function to check for NULL value,
but I get the following error
Compiler Error Message: BC30451: The name 'IsNull' is not declared.
Source Error:
Line 124: w = 800
Line 125: h = 400
Line 126: if IsNull(ctL) then
Line 127: If not IsNull(rs("wS")) then w = rs("wS")
Line 128: If not IsNull(rs("hS")) then h = rs("hS")
Source File: C:\\WebServers\\Gazeta\\default.aspx Line: 126
Which function should I use?
