Retrieving VFP runtime DLL name required by EXE or DLL

Submitted by Sergey on March 4, 2010 - 11:09

VFP stores in an EXE/DLL information about what runtime DLL is required to run it.

This is sample code. Add error handling and adjust to your requirements as necessary.

? VfpVersionFromExeOrDll("C:\Program Files\My Company\MyVfpApplication.exe")
? VfpVersionFromExeOrDll("X:\Somefolder\MyVfpDll.dll")
* VfpVersionFromExeOrDll.PRG
FUNCTION VfpVersionFromExeOrDll
LPARAMETERS tcExeDllName
LOCAL lcSig, lnHandle, lcVersion, lcBuffer, lnPos, lcSigMT
lnHandle = FOPEN(tcExeDllName, 0)
IF lnHandle < 0
    ? FERROR()
    RETURN "Unable to Open file + '" + tcExeDllName + "'"
ENDIF

How to pass parameters to VFP EXE

Submitted by Sergey on January 1, 2008 - 20:59

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
