Is there anything on that text file?

[HVi]

Again, sorry for the newbie question. Looked everywhere can't find it.
I want to know if a text file has anything on it, if so, a button will appear. If not, the button will stay hidden.

Thanks for your help.

Trying this with no luck:

contents = TextFile.ReadToString("AutoPlay\\Docs\\facebook.tx t");

error = Application.GetLastError();

if (error ~= 0) then
Dialog.Message("Error", _tblErrorMessages[error], MB_OK, MB_ICONEXCLAMATION);
else
Button.SetVisible("facebook", true);

error = Application.GetLastError();

if (error ~= 0) then
Dialog.Message("Error", _tblErrorMessages[error], MB_OK, MB_ICONEXCLAMATION);
end
end
