<Source>.CheckIndex (Function) In french: <Source>.VérifieIndex
Available only with these kinds of connection
Checks whether the data found in the index file (.NDX file) properly refers the data found in the data file (.FIC file). This function applies to the HFSQL data files (Classic or Client/Server) only.
Reminder: An index is corrupted when one of the referenced records is not the expected one. In this case, the data file must be re-indexed.

Syntax
<Result> = <Source>.CheckIndex([<Key item> [, <Progress Bar>]])
<Result>: Integer Can correspond to: - 0 if the check is correct.
- 1 if the index is corrupted: re-indexing is necessary (function <Source>.Index)
- 2 if an HFSQL error occurred: the data file cannot be accessed, etc.
- 3 if the function is not supported by this type of data file (xBase, AS400, etc.)
<Source>: Type corresponding to the specified source Name of the data file used. <Key item>: Optional character string Name of the key item to check. If this parameter is not specified, all the keys of the data file are checked. <Progress Bar>: Optional control name or window name - Name of window where the progress bar will be displayed,
- Name of the Progress Bar control to use.
Remarks Corrupted index When the function detects a problem in the index file, the H.Comment variable contains:
<Nom de la clé concernée> + TAB + <Numéro de l'enregistrement posant problème> + RC + <Nom de la clé concernée 2> + TAB + <Numéro de l'enregistrement posant problème 2> ...
<Record number causing problem> is equal to -1 if no record was defined. Remark: The H.Comment variable is not filled if the index file is entirely corrupted.
