CurDir Function

發行項
11/18/2006

Returns a string representing the current path.

The My.Computer.FileSystem Object gives you greater productivity and performance in file I/O operations than CurDir. For more information, see My.Computer.FileSystem.CurrentDirectory Property.

Public Overloads Function CurDir([ ByVal Drive As Char ]) As String

Parameters

Drive
Optional. Char expression that specifies an existing drive. If no drive is specified, or if Drive is a zero-length string (""), CurDir returns the path for the current drive.

Exceptions

Exception type	Error number	Condition
IOException	68	Drive is not found.
ArgumentException	68	Invalid Drive is specified.

See the "Error number" column if you are upgrading Visual Basic 6.0 applications that use unstructured error handling. (You can compare the error number against the Number Property (Err Object).) However, when possible, you should consider replacing such error control with Structured Exception Handling Overview for Visual Basic.

Remarks

This function returns a string representing the current path.

Example

This example uses the CurDir function to return the current path.

' Assume current path on C drive is "C:\WINDOWS\SYSTEM".
' Assume current path on D drive is "D:\EXCEL".
' Assume C is the current drive.
Dim MyPath As String
MyPath = CurDir()   ' Returns "C:\WINDOWS\SYSTEM".
MyPath = CurDir("C"c)   ' Returns "C:\WINDOWS\SYSTEM".
MyPath = CurDir("D"c)   ' Returns "D:\EXCEL".
