You're not being clear on what help you need, first post says change text style, the link I posted does that. In any case the vla-put methods cycling through the drawing database via (vlax-for Blk (vla-get-Blocks Doc), allows modification of entities inside blocks. SSGET and ENTUPD won't do that for you. Note your last code posted is missing and ENTUPD fuction to modify the blocks.
