Syntax
InfoDiskFree({ "optTagUpdateTrigger" })
optTagUpdateTrigger
An alphanumeric string enclosed in quotes, or the name of a String tag that contains the desired
string. This string, in turn, should be the name of the tag that will trigger the function — when
the value of this tag changes, the function is automatically executed. (Normally, a function
executes only when it is explicity called, such as with the Command animation.) To execute the
function at a regular interval, you can use one of project's system tags like Day or Month.
This parameter is optional.
Returned value
0 No
1 Yes
Notes
For this function, "Server" means the station that is actually running your project and has the TCP/IP Server
module enabled, and "Client" means a Thin Client or Secure Viewer that is communicating with the Server via
TCP/IP. For more information, see Configuring a Web Solution.
Tip: If the files on the Server are newer — that is, if this function returns TRUE — then you can use
ReloadAppFromServer to update the Client.
