How can I perform a file search if I can't distribute Filer.dll? by foxdev
Posted: 18 Jul 00

Microsoft's licensing for Visual FoxPro states that FILER.DLL cannot be distributed with the VFP runtime. It's a shame, because FILER.DLL provides some file search capabilities that are very easy to use.
But all is not lost. If your clients have any of the Microsoft Office applications (Word or Excel, for example), you can tap into the FileSearch object common to the Microsoft Office applications.
The code below demonstrates how to do this:
************************************
* -- demonstrates a file search using the Microsoft Office FileSearch class
* -- these defines are from the Object Browser in the VB editor
#define msoConditionAnytimeBetween 26
#define msoConnectorAnd 1
#define msoConnectorOr 2
#define msoSortbyFileName 1
#define msoSortbySize 2
#define msoSortbyFileType 3
#define msoSortbyLastModified 4
*****************************
lParameters tcFileSpec, tcStartingDir
if (not type('tcFileSpec') = "C")
return .F.
endif
if (not type('tcStartingDir') = "C")
tcStartingDir = curdir()
endif
* -- IMPORTANT: any of the Microsoft Office applications will suffice, as they
* -- all share the same FileSearch feature; I use Word here
oWord = createobject("Word.Application") && instantiate Word object
With oWord.FileSearch
.NewSearch && clears last results
.LookIn = tcStartingDir
.FileName = tcFileSpec
.SearchSubFolders = .T.
* -- normally, of course, these params would be passed
* -- I just threw this in to show this feature
.PropertyTests.Add("Last Modified", msoConditionAnytimeBetween, ;
"07/01/2000", "07/10/2000", msoConnectorAnd)
lnNumFiles = .Execute(msoSortbyFileName)
* -- the .FoundFiles collection now contains a list of found files
* -- .FoundFiles(1) yields the first file name, etc.
for each cFileName in .FoundFiles
* -- obviously, you'd do something a bit more practical
* -- than just listing them
? cFileName
endfor
EndWith
oWord.Quit
release oWord
