installer - Adding custom labels in NSIS dialog pages, showing and hiding labels in NSIS MUI Directory pages conditionally, how to get the ids of labels -

how hide custom label added on directory page dialog of nsis installer. label added using resource hacker , id 1300

how change text of label conditionally?

if user choses install demo, label text should "demo" , , if user choses install update , label text should "update"

i have added 2 labels, hiding , showing them accordingly.label1 id 1300 , label2 id 1301.

# occurs on directory page show. function directoryshow     ${if} $installtype == demo      getdlgitem $5 $hwndparent 1300 messagebox mb_ok "id of first label $5"  ----it shows '0' instead of showing 1300   ${nsd_settext} $5 "installing demo of software!!!!!!!!!!!!!!!!!"   getdlgitem $6 $hwndparent 1301 showwindow $6 ${sw_hide}  ;getdlgitem $1 $hwndparent 2 ;showwindow $0 ${sw_show} ;showwindow $1 ${sw_hide}   ${else}  getdlgitem $7 $hwndparent 1300 showwindow $7 ${sw_hide}  getdlgitem $8 $hwndparent 1301  ${nsd_settext} $8 "updating existing software !!!!!!!!!!!!!!!!!"   ${endif} functionend  

how id of these labels?

nsis uses child dialog host actual pages:

you first need handle inner dialog, can find label:

findwindow $0 "#32770" "" $hwndparent ;(this documented under section 4.9.14.6 in file) getdlgitem $5 $0 1300
