Remarks

File variables

HReset is used to reset the variables of HFSQL files. To reinitialize the variables of the HFSQL files in a page, you must use the following code:

HReset(<File Name>)
FileToPage()

Caution: If controls are associated with file items, these items contain stars ("*").

Remark: From version 19, HFSQL is the new name of HyperFileSQL.

Initialization process

Do not confuse Reset and PageInitialization. Indeed:

Reset resets the controls
PageInitialization resets the controls and runs the initialization processes.

Table and Looper controls

A Table or Looper control linked to a data file can never be empty. This control is automatically initialized with the values of the linked items in the data file.

Limits

Reset does not reinitialize the caption of the Button controls.

Reset has no effect on the following controls:

Static control,
Button control,
Image control.
