Icetips Utilities Documentation 5/9/2015     Windows Class: GetCommandLineLen

Previous  Top  Next

This method attempts to calculate the total length of a command line acceptable based on the operating system.  This is not failsafe and should be used only as a guideline.  Additional information about the maximum size of the command line can be found on Microsoft's Support website at http://support.microsoft.com/kb/830473 and on MSDN website at http://msdn2.microsoft.com/en-us/library/ms724834.aspx

This method can be used to determine if a constructed command line is too long for the operating system to pass it to another program.  If it is too long and you are passing filenames to another program, consider using ShortPath() on the filename before placing it in the command line. 

Example:

L  Long

ITW ITWindowsClass

Code

L = ITW.GetCommandLineLen()

Message('Maximum length of the command line is ' & L & ' characters.')
