Hello,

I was hoping to get some feedback on an Apex trigger I have written on the Salesforce platform. I have two custom objects (SalesOrder__c and Sales_Order_Line__c) that is a master/detail relationship.

On an edit of the line, I'm iterating over all the lines, running a check to see if the lines have been fully fulfilled and if so, then setting a fully fulfilled Boolean field on the master record to true. The check on the lines is looking at a custom formula field and the record type of the lines.

I'm interested in any feedback on the code I have written (see below) regarding best practices on bulkification, code logic, error handling, appropriate DML usage and governor limits.

For example, is it better to use standard DML operation or the database DML methods and use partial success? Should try/catch be used in triggers? I've read differing opinions on using error handling in triggers. Would a different loop be more efficient (do/while)? Should limit checks be added into the code? Any feedback on improvements and best practices would be welcome.

Please note, I'm using a trigger framework that uses a handler interface. The trigger calls the framework class, passing in the event to fire the trigger and the handler class to dispatch. The code below is the handler class that runs the logic on trigger after update event.

global class SalesOrderLineFullyFulfilled implements ITriggers.HandlerInterface {

	Sales_Order_Line__c[] newCollection =

How media type is different from content type or mime type. what is the meaning of payload. please advise

I have a website that uses a 32 bit dll created in C++ in 2000 that creates a one way hash. It works when called from a WEBSITES running on all the following windows servers.  2003,2008,2008r2,2012 and 2016. In other words on the 32 bit servers it runs from the windows\system32 directory and on the 64 bit servers is loads from the windows\SYSWOW64 directory. I am administrator on all the computers involved.

Website on 2012 r2 has 32 bit enabled on the .net 4.0 application pool. The dll is a standard dll and does not need to be registered.

I'd like to avoid requesting the client switch to 2012 or 2016 and I really would not like to have to create this as a web service and run it from another server where it is known to work.

Someone suggested that Group Policy for my login may have been changed. I know next to nothing about that sort of thing. I always request that the standalone webserver be set up with all standard settings.

    Private Declare Function VBEncrypt Lib "UtilitiesDll.dll" (ByVal lpPwd As String, ByVal lpEncrypt As String, ByVal nSize As Integer) As Integer
.
.
    Public Function HashPassword(ByVal Password As String) As String
        Dim EncryptedPassword As String = New String("*", 32)
        Encrypt.VBEncrypt(Password, EncryptedPassword, 32)
        Return EncryptedPassword
    End Function

UtilitiesDLL.dll gives the error, "Unable to load"
