Name
ChDir Procedure
Class
Microsoft.VisualBasic.FileSystem
Syntax
ChDir(path)-
path Use: Required
Data Type: String
The path of the directory to set as the new default directory
Description
Changes the current working (default) directory.
Rules at a Glance
pathcan be an absolute or relative reference.Changing the default directory does not change the default drive; it only changes a particular drive’s default directory.
Example
ChDir("c:\program files\my folder\")
ChDir("..") 'c:\program files is now the default directory.Programming Tips and Gotchas
The single dot (
".") represents the current directory and the double dot ("..") represents the parent of the current directory. If the root directory is the current directory, the statement:ChDir("..")
does not change the current directory and does not produce a syntax error.
If
pathis not found, or a FileNotFoundExeception exception, 76, “Path not found,” is generated. However, ifpathrefers to another machine on the network, error 75, “Path/File access error,” is generated.Although you can use a network path such as
\\NTSERV1\d$\TestDir\to change the current directory on the network admin share\\NTSERV1\d$, you can’t access this drive usingChDrivewithout having the drive mapped to a drive letter, which makes using network paths withChDira little pointless!Use
CurDirto determine the current directory for a particular drive.
