Overview
When handling analyses containing several descriptions of data files, the analysis graph is difficult to read. To manage these large analyses, WINDEV, WEBDEV and WINDEV Mobile propose Custom-Folders in the analysis.
Custom-Folders are used to group several descriptions of data files together.
These "Custom-Folders" are used to simplify:
  • the search and display of a data file description in a large analysis.
  • how the groups of data files are manipulated programmatically.
    For example, you can change the connection for all the data files in a Custom-Folder with HChangeConnection: to do so, specify the name of the Custom-Folder that must be handled in the WLanguage function (see the list of available functions below).
    This feature is available for HFSQL Classic data files, HFSQL Client/Server data files and data files handled by Native Access.
These groupings are defined in the "Analysis" pane or in the analysis graph. These Custom-Folders are not physically created.
The following example groups the data files according to their category:
Limitations:
  • A Custom-Folder can be empty and contain no data file description.
  • It is not mandatory to associate a data file description to a Custom-Folder.
  • A Custom-Folder cannot belong to another Custom-Folder.
  • Two Custom-Folders cannot have the same name.
  • A Custom-Folder cannot have the same name as a data file description.
Handling the Custom-Folders in the analysis
The different operations that can be performed on the Custom-Folders of the analysis are as follows:
  • create a Custom-Folder.
  • rename a Custom-Folder.
  • delete a Custom-Folder.
  • associate a file description with a Custom-Folder.
  • dissociate a file description from a Custom-Folder.
To handle the Custom-Folders in the analysis, the "Analysis" pane must be displayed. To display the "Analysis" pane, go to the "Home" tab, "Environment" group, expand "Panes", select "Panes" and then select "Analysis".

Handling a Custom-Folder

To create a Custom-Folder:
  1. In the "Analysis" pane (or in the analysis graph), select "New Custom-Folder" in the context menu (right click). A new Custom-Folder is automatically created.
  2. Enter the name of this Custom-Folder and confirm (Enter key).
To rename a Custom-Folder:
  1. Select the Custom-Folder to rename in the "Analysis" pane.
  2. Open the context menu (right click) and select "Rename" (or press F2).
  3. Enter the new name of this Custom-Folder and confirm (Enter key).
To delete a Custom-Folder:
  1. Select the Custom-Folder to delete (in the "Analysis" pane or in the analysis graph).
  2. Open the context menu (right click) and select "Delete".
  3. The Custom-Folder is deleted. The data files associated with this Custom-Folder are automatically dissociated from this Custom-Folder.
To associate a file description with a Custom-Folder:
  1. Select the file description that must be associated with the Custom-Folder.
  2. Drag and Drop the description in the desired Custom-Folder. The description is automatically associated with the Custom-Folder.
    Remark: If the description already belonged to a Custom-Folder, the description is only associated with the new Custom-Folder.
To dissociate a file description from a Custom-Folder:
  1. Select the file description to dissociate in the "Analysis" pane.
  2. Right-click to open the context menu and select "Remove from Custom-Folder".
  3. The file description is automatically dissociated from the Custom-Folder.
Actions that can be performed on a Custom-Folder

Customizing the graphic representation of the Custom-Folder

Customizing a Custom-Folder consists in displaying a specific background image in the Custom-Folder.
To customize the graphic representation of a Custom-Folder:
  1. Select the Custom-Folder in the analysis graph.
  2. Right-click to open the context menu and select "Description".
  3. Check "Representation of the Custom-Folder in the analysis graph" and select the desired image. This image will be displayed in the graphic representation of the Custom-Folder.
  4. Validate.

Printing the content of the Custom-Folder

You have the ability to print the documentation of the elements found in the Custom-Folder:
  1. Select the Custom-Folder in the "Analysis" pane.
  2. Open the context menu (right click) and select "Print".
Handling groups/Custom-Folders programmatically
Several WLanguage functions can be used to handle Custom-Folders through programming:
HChangeConnectionDynamically changes the connection associated with a data file.
HChangeDirChanges the path to a data file (i.e. directory in which the file will be handled).
HChangeLocationModifies the search mode of physical data files (.FIC, .NDX, ...).
HCloseCloses a data file or all the data files opened by the current user: all the corresponding physical data files are closed for the current user.
HCreationIfNotFoundPerforms the following operations:
  • If the data file doesn't exist, create a data file (extension file ".FIC") with index file and memo file if necessary. The function is equivalent to HCreation..
  • If the data file exists, opens the data file.
HFlushForces the operating system of the computer where the data files are found to write data onto the disk.
HListFileReturns the list of files:
  • analysis in progress.
  • of analyses in progress (case of projects with multiple analyses).
  • specific analysis recognized by the HFSQL engine.
  • available on an Native Connector or OLE DB driver connection.
  • for a group of files defined in the data model editor.
HOpenOpens a data file.
HPassDefines the password used to create or open a data file.
Minimum version required
  • Version 9
