Another droplist question
Hi,

I need to attach an id to every item in a droplist.
The droplist has a few items: "item1", "item2", "item3" etc.
The user selected item of the droplist is for example: "item1" which corresponds to number 435 "Item 2" corresponds to number 256, "item3" has number 92 etc.

1) How can I assign a number to a droplist item?

2) Is it possible to get the itemindex of the selection droplist?

Regards! :p

IO doesn't offer such a feature so you will have to compare the State value to every possible item and assign a number to a variable according to it.

For example:

ReadIniStr$0 file.ini "field 6" state

StrCmp$0 "item 1" 0 +3

  StrCpy$1 435

  Goto done

StrCmp$0 "item 2" 0 +3

  StrCpy$1 256

  Goto done

># ...

>done:

An easier way of doing it will be defining a macro:

!macro ITEM_TO_NUMBER item number

StrCmp$0 "${item}" 0 +3

  StrCpy$1 ${number}

  Goto done

>!macroend


ReadIniStr$0 file.ini "field 6" state

>!insertmacro ITEM_TO_NUMBER "item 1" 256

>!insertmacro ITEM_TO_NUMBER "item 2" 543

>!insertmacro ITEM_TO_NUMBER "item 3" 656

># ...
