Code: ;Look at macro/resource.inc: macro dialogitem class,title,id,x,y,cx,cy,style,exstyle ;so, line dialogitem 'STATIC',ID_VENDOR,-1,62,19,130,8,WS_VISIBLE ;must be dialogitem 'STATIC','',ID_VENDOR,62,19,130,8,WS_VISIBLE

Thank You so much SFeLi.
That solves that. It still amazes me that with all complicated code (not that this is complicated) bugs are created from the most basic things. I cant thank you enough. |
