  • Is there anything on that text file?

    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
