Substring Search
Hi,

I'am trying to write a script that find the path to an OCX or a DLL.

Section "Apex Test" Apex_01
        
    ;Open search
    registry::Open /NOUNLOAD "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDLLs" "/N='apexexchangeXcontrol2.ocx'" .r0
        StrCmp $0 -1 error

        registry::Find /NOUNLOAD .r1 .r2 .r3 .r4
    
    MessageBox MB_OKCANCEL '$$1    "path"   =[$1]$\n\
                            $$2    "value"  =[$2]$\n\
                            $$3    "string" =[$3]$\n\
                            $$4    "type"   =[$4]$\n\
                                                 $\n\' 
                    
    ;Close search 
    registry::Close
        
    error: 

    
SectionEnd

The problem is that i have to give the full path ("/N='C:\Windows\system32\apexexchangeXcontrol2.ocx'") so that the plugins returm a result.

Is there a way to search for a substring in the key?

nsis already has built in registry support for this, use EnumRegValue and parse each path returned and look for your ocx/dll, to parse the returned string, you can do it yourself, or use the GetFileName macro (see E.1 "File Functions Header" in the nsis help file)
