When you write Microsoft Visual Basic for Applications macros or routines, you may need to test whether another process already opened a file before you perform any operations on the file. This article contains a sample macro and function to test the current access status of a file or document.
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following sample Visual Basic for Applications macro calls the FileLocked function and passes the full path and name of the file for testing. If the function returns True, error number 70 "Permission Denied" has most likely occurred, and the file is currently open and locked by another process. If the function returns False, the file is not open, and the macro opens the document.
