|
listboxname |
The name of the ListBox control from which you want |
|
selection |
A string variable in which the selected path name |
Return value
Boolean.
Returns true if the current selection is a drive letter or a
directory name (which can contain files and other directories) and
false if it is a file (indicating the user’s final choice). If any
argument’s value is null, DirSelect returns null.
Usage
Use DirSelect in the SelectionChanged event to find out what the
user chose. When the user’s selection is a drive or directory, use the
selection as a new directory specification for DirList.
Examples
The following script for the SelectionChanged event for the ListBox
lb_FileList calls DirSelect to test whether the user’s selection is a
file. If not, the script joins the directory name with the file pattern,
and calls DirList to populate the ListBox and display the current drive
and directory in the StaticText st_FilePath. If the current selection is a
file, other code processes the file name:
|
1 2 3 4 5 6 7 8 9 10 11 |
string ls_filename, ls_filespec = "*.TXT" IF lb_FileList.DirSelect(ls_filename) THEN //If ls_filename is not a file, //append directory to ls_filespec. ls_filename = ls_filename + ls_filespec lb_filelist.DirList(ls_filename, & 16400, st_FilePath) ELSE ... //Process the file. END IF |
