CB_FINDSTRING using SendMessage problem
Hello,
I am having trouble searching for a string in a combobox using winmessages.nsh
I must be doing something wrong because every time it just returns -1. I am not sure where i am going wrong. Here is some code to try it on...

Name test
OutFile test.exe
XPStyle on
!include nsDialogs.nsh
!include "WinMessages.nsh"
Page custom GUI
Page instfiles


var /global testbutton
var /global COMBOBOX


Function GUI

        nsDialogs::Create 1018


        ${NSD_CreateButton} 0 190 30% 12u "test button"
        pop $testbutton
        ${NSD_OnClick} $testbutton testbutton


        ${NSD_CreateComboBox} 0 30 80% 12u "test"
        pop $COMBOBOX
        ${NSD_CB_AddString} $COMBOBOX "test"
        ${NSD_CB_SelectString}  $COMBOBOX "test"
        
nsDialogs::Show
FunctionEnd


Function testbutton

StrCpy $R0 "test"
SendMessage $COMBOBOX ${CB_FINDSTRING} -1 $R0 $1
messagebox mb_ok "$1"

FunctionEnd

SectionEnd

Many thanks if you have any help! :)

With SendMessage you need to prefix string parameters with "STR:".

Example:

Function testbutton

StrCpy $R0 "test"
SendMessage $COMBOBOX ${CB_FINDSTRING} -1 "STR:$R0" $1
messagebox mb_ok "$1"

FunctionEnd
