Share Creation

The following shows how you can create a directory tree and share it. Note that Windows 2003 has a /GRANT parameter to assign privledges to the share, for other operating systems or for complex requirements you can use an external program (such as "SetACL.exe" - demonstrated below).

EXAMPLE: SHARE CREATION/REMOVAL

Note that share creation can be problematic if clients are accessing it, for this reason I tend to leave the share alone on uninstall (but you may not be able to do this).

;--- Create directories and set required access -----------------------------
<$Component "CreateShare" Create="Y" Directory_="INSTALLDIR" LM="Y">
   ;--- Create share directories --------------------------------------------
   <$DirectoryTree Key="SHARE_ROOT_DIR" Dir="C:\DATA\SomeDir"          MAKE="Y">
   <$DirectoryTree Key="SHARE_SUBDIR1"  Dir="[SHARE_ROOT_DIR]\SubDir1" MAKE="Y">
   <$DirectoryTree Key="SHARE_SUBDIR2"  Dir="[SHARE_ROOT_DIR]\SubDir2" MAKE="Y">

   ;--- Create appropriate permissions --------------------------------------
   <$TABLE "LockPermissions">
       ;--- Do everything for these "groups" --------------------------------
       #define ForTheseUsers  Users Administrators

       ;--- Define the changes ----------------------------------------------
       #{  SET ^@@Group={ }<$ForTheseUsers>^
           ;--- Need full access to the share -------------------------------
           #(
               <$Row
                   LockObject="SHARE_ROOT_DIR"
                        Table="CreateFolder"
                   Permission="<$PRIVILEGE_GENERIC_ALL>"
                       Domain="" User="<??SET_@@Group>"
               >
           #)
       #}
   <$/TABLE>
<$/Component>

;--- Create a custom action to create/delete share --------------------------
#data "CaDataShare"
   "SHARE_ROOT_DIR" '[SHARE_ROOT_DIR]'
#data
<$VbsCa Binary="Share.vbs" DATA=^CaDataShare^>
   ;--- INSTALL -------------------------------------------------------------
   <$VbsCaEntry "CreateShare">
       NetCmd("""MyShare={dir}"" /UNLIMITED /REMARK:""Short Comment (<$ProdInfo.ProductName>)""")
   <$/VbsCaEntry>

   ;--- UNINSTALL -------------------------------------------------------------
   <$VbsCaEntry "RemoveShare">
       NetCmd("MyShare /delete")
   <$/VbsCaEntry>

   ;=========================================================================
   sub NetCmd(Parameters)
   ;=========================================================================
       ;--- Get the share directory name ------------------------------------
       dim ShareDir : ShareDir = VbsCaCadGet("SHARE_ROOT_DIR")
       if  right(ShareDir, 1) = "\" then
           ShareDir = left(ShareDir, len(ShareDir)-1)
       end if

       ;--- Ignore the return code ------------------------------------------
       VbsCaRunSync "net share " & replace(Parameters, "{dir}", ShareDir), 0, ""
   end sub
<$/VbsCa>

;--- Shedule the above custom action ----------------------------------------
<$VbsCaSetup Binary="Share.vbs" Entry="CreateShare" Seq="StartServices-" Condition=^<$CONDITION_EXCEPT_UNINSTALL>^ DATA=^CaDataShare^ Key="ShareCreate">
<$VbsCaSetup Binary="Share.vbs" Entry="RemoveShare" Seq="StartServices-" Condition=^<$CONDITION_UNINSTALL_ONLY>^   DATA=^CaDataShare^ Key="ShareDelete">

EXAMPLE: SHARE CREATION + SetACL.EXE

#define SHARE_DIR           TheSharesName

    <$File Source="SetACL.exe"  Comment=^Used to set security on the created share.^ KeyPath="Y">

<$VbsCa Binary="CreateShare.vbs" DATA=^CaData^>
   ;--- INSTALL -------------------------------------------------------------
   <$VbsCaEntry "DuringInstall">
        ;--- Init -----------------------------------------------------------
        CaDebug 1, "Creating the share"
        dim SetAclExe : SetAclExe = VbsCaCadGetValidate("SETACL.EXE", "FILE")
        dim ShareDir  : ShareDir  = VbsCaCadGetValidate("SHARE_DIR",  "DIR")
        if  right(ShareDir, 1) = "\" then
            ShareDir = left(ShareDir, len(ShareDir)-1)
        end if

        ;--- Create the share (/GRANT is WIN2003+) --------------------------
        dim NetCmd
       'NetCmd   = "net share <$SHARE_DIR_SHARE>=" & ShareDir & " /UNLIMITED /GRANT:<$SHARE_DIR_USER>,FULL /REMARK:""A comment"""
        NetCmd   = "net share <$SHARE_DIR_SHARE>=" & ShareDir & " /UNLIMITED /REMARK:""A comment"""
        VbsCaRunSync NetCmd, 0, ""

        ;--- Grant permissions to the share ---------------------------------
