public static Microsoft.VisualBasic.FileAttribute GetAttr (string PathName);
String expression that specifies a file, directory, or folder name.
PathName can include the directory or folder, and the drive.
The value returned by
GetAttr is the sum of the following enumeration values:
| Value |
| Constant |
These enumerations are specified by the Visual Basic language. The names can be used anywhere in your code in place of the actual values.
Pathname is invalid or contains wildcards.
Target file does not exist.
This example uses the
GetAttr function to determine the attributes of a file and directory or folder.
Dim MyAttr As FileAttribute ' Assume file TESTFILE is normal and readonly. MyAttr = GetAttr("C:\TESTFILE.txt") ' Returns vbNormal. ' Test for normal. If (MyAttr And FileAttribute.Normal) = FileAttribute.Normal Then MsgBox("This file is normal.") End If ' Test for normal and readonly. Dim normalReadonly As FileAttribute normalReadonly = FileAttribute.Normal Or FileAttribute.ReadOnly If (MyAttr And normalReadonly) = normalReadonly Then MsgBox("This file is normal and readonly.") End If ' Assume MYDIR is a directory or folder. MyAttr = GetAttr("C:\MYDIR") If (MyAttr And FileAttribute.Directory) = FileAttribute.Directory Then MsgBox("MYDIR is a directory") End If
To determine which attributes are set, use the
And operator to perform a bitwise comparison of the value returned by the
GetAttr function and the value of the individual file attribute you want. If the result is not zero, that attribute is set for the named file. For example, the return value of the following
And expression is zero if the
Archive attribute is not set:
Result = GetAttr(FName) And vbArchive
A nonzero value is returned if the
Archive attribute is set.
