How to pass parameters to VFP EXE

Passing command-line parameters from Windows to VFP created EXE is different from passing parameters to VFP programs or functions in VFP application:

  • All parameters are passed to EXE as strings
  • Parameters should not be enclosed in single quotes because quotes will be treated as part of parameter
  • Parameters with spaces can be enclosed in double quotes
  • Parameters are separated by spaces not commas
