The way you're doing it with all the readlines when you assign the
text does not give you much opportunity to do anything different
You need to read in the lines and then join them together in 2 steps
instead of one like you currently have
Something like
Dim f as folderitem = DocumentsFolder.child("My Temp1 File")
Dim tis as TextInputStream = f.OpenAsTextFile
dim i as integer
dim line as string
dim lines(-1) as string
If tis is nil then
//check f.LastErrorCode
Return
End if
for i = 1 to 8
line = tis.readline
if line <> "" then
lines.append line
end if
next
EditField10.text = join(lines, ", ")
