I'm trying to send an html e-mail from within SSIS 2014 using Visual Studio 2012. I've tried building the html code and passing it via a variable i.e. User::MailBody. I've tried assigning it to a string i.e. Dim HtmlBody. I've also tried building it within the script i.e. messagebody. None of these work though and I keep getting the following error message:
DTS Script Task has encountered an exception in user code: Project Name: ST_f9d4d770db5047e4beada34f28665e6a Exception has been thrown by the target of an invocation. at System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor) at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture) at System.RuntimeType.InvokeMember(String name, BindingFlags bindingFlags, Binder binder, Object target, Object[] providedArgs, ParameterModifier[] modifiers, CultureInfo culture, String[] namedParams) at Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTATaskScriptingEngine.ExecuteScript()
