Folder selection dialog from EKL Action?

Hi All - I'm trying to write an EKL action which will output some data to a text file.  I would like to give the user the opportunity to select a folder for the file to be saved in.  So far I've not found a way to bring up a windows folder browser window from an EKL Action ... is this not possible?

I've found a way to do this using a VBScript action, and thought that maybe my EKL action could run the VBScript action, and that could pass the selected folder path back to the EKL Action ... can't see a way to do this either.  Can a VBScript action return a value / object back to the EKL action that ran it?

I know what I want to do can all be done with a VBA macro, but would like to try and do it with EKL if it's possible.  Still learning ... any help would be much appreciated.

Indeed you should use the VBScript to preform the CATIA.FileSection. Then you can set a String type Knowledge parameter to the filepath, and read this string using EKL.

// VBAction

CATIA.FileSelectionBox("Select input file", "*.xls; *.xlsx", CatFileSelectionModeOpen)

// EKL
`MyPart --.--1\strTmpDir` = ""

let vbOpenExcel (VBScript)
vbOpenExcel = `MyPart --.--1\Relations\VBLib\getExcelFile`
vbOpenExcel.Run( `MyPart --.--1\strTmpDir` )

let sPathExcelFile (String)
sPathExcelFile = `MyPart --.--1\strTmpDir`

if sPathExcelFile <> "" and sPathExcelFile.MatchPattern(".*.xls.?")
{
Trace(1,"OK : #",sPathExcelFile)
}
else
{
Trace(1,"NO: user cancel")
exit
}
