FileAttr function FileAttr Function [Runtime] Returns the access mode or the file access number of a file that was opened with the Open statement. The file access number is dependent on the operating system (OSH = Operating System Handle).

If you use a 32-Bit operating system, you cannot use the FileAttr-Function to determine the file access number. See also: Open Syntax: FileAttr (FileNumber As Integer, Attribute As Integer) Return value: Integer Parameters: FileNumber: The number of the file that was opened with the Open statement. Attribute: Integer expression that indicates the type of file information that you want to return. The following values are possible: 1: The FileAttr-Function indicates the access mode of the file. 2: The FileAttr-Function returns the file access number of the operating system. If you specify a parameter attribute with a value of 1, the following return values apply: 1 - INPUT (file open for input) 2 - OUTPUT (file open for output) 4 - RANDOM (file open for random access) 8 - APPEND (file open for appending) 32 - BINARY (file open in binary mode). Example: Sub ExampleFileAttr Dim iNumber As Integer Dim sLine As String Dim aFile As String aFile = "c:\data.txt" iNumber = Freefile Open aFile For Output As #iNumber Print #iNumber, "This is a line of text" MsgBox FileAttr(#iNumber, 1 ),0,"Access mode" MsgBox FileAttr(#iNumber, 2 ),0,"File attribute" Close #iNumber End Sub
