HSubstDir (Function) In french: HSubstRep
![OLE DB OLE DB](https://doc.pcsoft.fr/ext/images/us/OLEDB.png?-749475651) Available only with these kinds of connection
Associates the data directory specified in the analysis with a directory found on disk. Once HSubstDir has been run, all the data files associated with the directory specified in the analysis will be handled in the indicated directory. Caution: The data files must be closed beforehand ( HClose). To modify the path of a single data file, use HChangeDir. Syntax
<Result> = HSubstDir(<Directory of files specified in analysis> , <Physical directory of files on disk>)
<Result>: Boolean This parameter is always equal to True. If an error occurs, the next function for accessing the data file will return False. For example, if the specified physical directory does not exist, a directory error will occur during the first access to the data file. <Directory of files specified in analysis>: Character string Name of the directory specified during the description of the data file. <Physical directory of files on disk>: Character string New name of the directory (up to 260 characters). A UNC path can be used.HSubstDir is ignored if the specified directory contains data files in a format other than HFSQL. Remarks Multiple directory substitutions HSubstDir can be called several times with different parameters. When the physical directory is redefined several times for the same logical directory (described in the analysis), the last specified physical directory replaces all the other ones. HChangeDir is used to associate a directory with a data file. To replace a directory with another one, use HSubstDir. Caution: the change of directory performed by HSubstDir applies to the directory defined by HChangeDir. For example: HSubstDir("C:\Statistics\January", "C:\New\JanStats") HChangeDir(Stat, "C:\Statistics\January") HCréation(Stat) //File created in C:\New\JanStats
- If the management of ".REP" is enabled (HSetREP), the modification of the path is saved in the ".REP" file (see management of .REP files).
- The new path is stored when the data file is closed.
- The number of substitutions is unlimited.
