Transfer the template string Asour which is BASE64 formatted into the Variant-typed template Asour used by the control.
The above-mentioned two methods are mainly used for saving database of templates. Variant-typed templates are saved in the manner
of binary-formatted arrays, which are quite difficult for languages such as PB, VB, etc. Method EncodeTemplate can transfer
Variant-typed codes into strings, and method DecodeTemplate can transfer string-typed codes into codes of Variant-typed. Here,
we should pay attention that the template length will be increased after the template variable BASE64 code has been transferred
into the string.
