FileNumber does not exist.



File mode is invalid.

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.

This function assigns an output line width to a file opened using the FileOpen function.

This example uses the FileWidth function to set the output line width for a file.

Dim i As Integer
FileOpen(1, "TESTFILE", OpenMode.Output) ' Open file for output.
FileWidth(1, 5)   ' Set output line width to 5.
For i = 0 To 9   ' Loop 10 times.
   Print(1, Chr(48 + I))   ' Prints five characters per line.
FileClose(1)   ' Close file.

This function is not supported.
