I have searched and am unable to find something like this.
Is it possible to look for a certain string within a string?
Sort of like:

string = "123xyz567"
if string contains "xyz"
do something
end if

Thanks

You're looking for InStr: http://sdkdocs.roku.com/display/sdkdoc/ ... gAsInteger

Thank you theEndless, i looked at that and don't see any "compare" or "contains' type items there. None of the things there are defined, so i could be missing it or just be dense. Which one will do this?

edit ok i see your whole URL now, but i dont see how the As Integer part works

Thanks

if str.Instr("xyz") As integer ) As integer

I'm not seeing how this could be true or false which is what i need.

if str.Instr("xyz") ) = true

8.5 Instr(start As Integer, text As String, substring As String) As Integer

Returns the position of the first instances of substring within text, starting at the specified start position. Returns 0 if the substring is not found. The first position is 1.

So anything greater than zero means the string was found:

if Instr(str, "xyz") > 0 then
   Found()
else
   NotFound()
end if

The stringops version works the same except indexes are zero-based so -1 is the "not found" case:

if str.Instr("xyz") >= 0 then
   Found()
else
   NotFound()
end if

Thank you Mark, I got it now. All this stuff seems impossible when you don't know, and easy when you do.

thanks again.
