Dim objFSO,objFile,Count,strLine,strLineCase,strNewFile

Set objFSO=CreateObject("Scripting.FileSystemObject")

Set objFile=objFSO.OpenTextFile(strFile,ForReading)

Do Until objFile.AtEndOfStream

strLine=objFile.Readline

If CheckCase=0 then strLineCase=ucase(strLine):strKey=ucase(strKey)

If LineNumber=objFile.Line-1 or LineNumber=0 then

If instr(strLine,strKey) or instr(strLineCase,strkey) or strKey="" then

strNewFile=strNewFile

Else

strNewFile=strNewFile&strLine&vbcrlf

End If

Else

strNewFile=strNewFile&strLine&vbcrlf

End If

objFile.Close

Set objFSO=CreateObject("Scripting.FileSystemObject")

Set objFile=objFSO.OpenTextFile(strFile,ForWriting)
