>How can I determine what version of VFP was used to create an executable?

Jeff,

You can look for string "VisualFoxProRuntime." in the exe. VFP version used to create exe follows it.

lcExeName = "test.exe"
lcSearchStr = "VisualFoxProRuntime."
lcBuffer = FILETOSTR(lcExeName)
lcVFPversion = SUBSTR(lcBuffer, ;
			AT(lcSearchStr, lcBuffer) + LEN(lcSearchStr),1)
? lcVFPversion
