Operating mode in Windows Vista (and later)

If this function does not operate properly in Windows Vista (and later), check whether the file or directory used is not in one of the system directories (Windows directory or "Program Files" directory).
Indeed, in Windows Vista (and later), with the UAC mechanism (User Account Control) enabled, you must have the administrator privileges to handle and/or modify the files or directories in the system directories (Windows directory or "Program Files" directory).
Programming tip: To handle and/or modify the files or directories without administrator privileges, you should:
  • avoid writing into the Windows directory or into the "Program Files" directory,
  • use the system directory corresponding to the application (returned by SysDir associated with the srCommonAppData constant).
Remark: In Windows Vista (and later), the virtualization mechanism is used to make the applications compatible with Vista. If the file is created in a system directory without having sufficient rights, this file will actually be created in another directory (C:\Users\<LOGIN>AppData\Local\VirtualStore\Windows\). In this case, the file cannot be shared between several applications.
Versions 19 and later

Procedure that is using each copied file (syntax 2 only)

For each file found, fCopyDir automatically calls the <Procedure name> procedure. This procedure is a local or global procedure.
To create this procedure:
  1. Create a global procedure (from the code editor: on the "Code" pane, in the "Procedures" group, expand "New" and select "New global procedure").
  2. Fill the procedure declaration as follows:
    PROCEDURE <Procedure name> (<Path of file to copy>, <Path of destination file>,
    <Change>, <Procedure pointer>)
    • <Path of file to copy> is the path of the file to copy.
    • <Path of destination file> is a character string containing the name of the destination file.
    • <Change> is a constant set to:
      • flFirstFile when the file is the first file copied into the <Source file> directory.
      • flChangeDir when the file is the first file listed in a subdirectory of <Path of directory to copy> (which means that a change of directory occurred).
      • flFile in all the other cases.
      The different values that can be taken by <Change> are as follows:
      Current file<Change>
      Dir\File 1flFirstFile
      Dir\File nflFile
      Dir\SubDir 1\File 1flChangeDir
      Dir\SubDir 1\File mflFile
      Dir\SubDir 2\File 1flChangeDir
      Dir\SubDir 2\File xflFile
  • <Procedure pointer> is an integer whose value is the one passed to the <Pointer> parameter of fCopyDir. If <Pointer> is not specified, <Pointer> is set to 0.
To retrieve the value of <Procedure pointer>, its value must be assigned to the value of <Pointer> in the procedure with Transfer.
Remark: The parameters of this procedure are optional: you can for example only specify the path of the file to copy and the path of the destination file.

To create this procedure:
  1. Create a global procedure (from the code editor: on the "Code" pane, in the "Procedures" group, expand "New" and select "New global procedure").
  2. Fill the procedure declaration as follows:
    PROCEDURE <Procedure name> (<Path of file to copy>, <Path of destination file>,
    <Change>, <Procedure pointer>)
    • <Path of file to copy> is the path of the file to copy.
    • <Path of destination file> is a character string containing the name of the destination file.
    • <Change> is a constant set to:
      • flFirstFile when the file is the first file copied into the <Source file> directory.
      • flChangeDir when the file is the first file listed in a subdirectory of <Path of directory to copy> (which means that a change of directory occurred).
      • flFile in all the other cases.
      The different values that can be taken by <Change> are as follows:
      Current file<Change>
      Dir\File 1flFirstFile
      Dir\File nflFile
      Dir\SubDir 1\File 1flChangeDir
      Dir\SubDir 1\File mflFile
      Dir\SubDir 2\File 1flChangeDir
      Dir\SubDir 2\File xflFile
  • <Procedure pointer> is an integer whose value is the one passed to the <Pointer> parameter of fCopyDir. If <Pointer> is not specified, <Pointer> is set to 0.
To retrieve the value of <Procedure pointer>, its value must be assigned to the value of <Pointer> in the procedure with Transfer.
Remark: The parameters of this procedure are optional: you can for example only specify the path of the file to copy and the path of the destination file.

For each file found, fCopyDir automatically calls the <Procedure name> procedure. This procedure is a local or global procedure.
To create this procedure:
  1. Create a global procedure (from the code editor: on the "Code" pane, in the "Procedures" group, expand "New" and select "New global procedure").
  2. Fill the procedure declaration as follows:
    PROCEDURE <Procedure name> (<Path of file to copy>, <Path of destination file>,
    <Change>, <Procedure pointer>)
    • <Path of file to copy> is the path of the file to copy.
    • <Path of destination file> is a character string containing the name of the destination file.
    • <Change> is a constant set to:
      • flFirstFile when the file is the first file copied into the <Source file> directory.
      • flChangeDir when the file is the first file listed in a subdirectory of <Path of directory to copy> (which means that a change of directory occurred).
      • flFile in all the other cases.
      The different values that can be taken by <Change> are as follows:
      Current file<Change>
      Dir\File 1flFirstFile
      Dir\File nflFile
      Dir\SubDir 1\File 1flChangeDir
      Dir\SubDir 1\File mflFile
      Dir\SubDir 2\File 1flChangeDir
      Dir\SubDir 2\File xflFile
  • <Procedure pointer> is an integer whose value is the one passed to the <Pointer> parameter of fCopyDir. If <Pointer> is not specified, <Pointer> is set to 0.
To retrieve the value of <Procedure pointer>, its value must be assigned to the value of <Pointer> in the procedure with Transfer.
Remark: The parameters of this procedure are optional: you can for example only specify the path of the file to copy and the path of the destination file.
Versions 19 and later

Values returned by the procedure (Syntax 2)

The <Procedure name> procedure must return one of the following values:
fcStopUsed to stop the copy permanently.
fcCopyUsed to continue the copy.
fcIgnoreUsed to ignore the copy of a file.
A WLanguage error occurs if the procedure does not return one of these values.
Case 1. Full interruption of copy
To force the interruption of copy, the <Procedure name> procedure must return the fcStop constant.
Example: the "CopyProduct" procedure is automatically called by fCopyFile:
PROCÉDURE CopyProduct(PathSourceFile, PathDestinationFile)
...
// Stop requested?
Multitask(-1)
IF KeyPressed(kpEscape) = True THEN
Info("The copy will be stopped")
RESULT fcStop
END
...
RESULT fcCopy
If the Esc key is pressed, fCopyDir returns the fcStop constant.
In the other cases (to continue the browse), the <Procedure name> procedure returns the fcCopy constant.
Case 2. Partial interruption of copy
In order for the <Procedure name> procedure not to be run for a given file, the <Procedure name> procedure must return the fcIgnore constant.
Example: The "FindProduct" procedure is automatically called by fCopyFile:
PROCÉDURE FindProduct(PathSourceFile, PathDestinationFile)
...
// File to ignore
IF StringEndsWith(PathSourceFile, "WrongFile.XLS") THEN
RESULT fcIgnore
END
...
RESULT fcCopy
To avoid copying the "WrongFile.XLS" file, the procedure returns the fcIgnore constant. The <Procedure name> procedure is automatically called for the next copied file, without copying the current file.
