Icetips Utilities Documentation 11/14/2010     Core Class: IsFileInUse

Previous  Top  Next

This method attempts to open the specified file in GENERIC_WRITE mode to see if it can be opened for writing.  If not, it is deemed in use by some other program or process.  If the file can be opened the method returns false.  A file that is in use can generally be opened for reading.  This method is very useful for operations such as deleting files or opening them with write access.  If the file is in use it can't be written to.  It is overloaded with a method that takes a *CString parameter so it can be used with both string variables and CString variables.

Example:

ITC ITCoreClass

Fn  CString(2049)

 Code

 Fn = ITC.EXEName

 ITC.ODS('ExeName = ' & Fn)

 If ITC.IsFileInUse(Fn) !! Should ALWAYS return true

   Message('This program is in use.')

 Else

   Message('This program is not in use (should never happen)')

 End

 Fn = ITC.GetFilePart(ITC.EXEName,FNS_FullPath+FNS_File) & '.app'

 ITC.ODS('AppName = ' & Fn)

 If ITC.IsFileInUse(Fn) !! Should not be in use.

   Message('This appfile is in use.')

 Else

   Message('The appfile is not in use.')

 End
