    Hi,
    I want to handle visu users via code.
    One of the main topics is to read the users (and groups) list.
    I'm testing the method "GetUsers" of VisuUserManagement.VisuUserMgmt but my system crash.
    The code looks good, I can't understand.

    This is the code implemented:

    VAR
   iFBUserMng   : VisuUserManagement.VisuUserMgmt;
   stRet      : VisuUserManagement.VUM_ReturnValues;
   
   udiNumberOfUsers   : UDINT;
   dwUserDB         : DWORD;
   xUpdateUserList      : BOOL;
   
   astUserList         : ARRAY[0..10] OF VisuUserManagement.VUM_User;
   dwpUserList         : POINTER TO ARRAY[0..0] OF VisuUserManagement.VUM_User;
   udiUserListSize   : UDINT;
END_VAR
IF xUpdateUserList THEN
   dwUserDB := iFBUserMng.GetUserDBAsCopy();
   udiNumberOfUsers := iFBUserMng.GetUserCount(dwUserDB);
   xUpdateUserList := FALSE;
   
   dwpUserList := ADR(astUserList);
   udiUserListSize := SIZEOF(astUserList); 
   
   
   stRet := iFBUserMng.GetUsers(
                  dwUserDB:= dwUserDB, 
                  udiStartIndex:= 1, 
                  udiEndIndex:= 1, 
                  pArr:= dwpUserList, 
                  udiArrSize:= udiUserListSize);
   
END_IF;

    I'm not sure, but

     dwpUserList         : POINTER TO ARRAY[0..0] OF VisuUserManagement.VUM_User;

    seems strange.

    I tested it in thousand ways...this is just the last version.

    I already tested:

    dwpUserList         : POINTER TO ARRAY[0..10] OF VisuUserManagement.VUM_User;

    And also with ARD(...) and SIZE_OF(...) directly on the method call.

    Hello, does someone has an update? How can all existing users be retrieved? Kind regards!
