Replace existing file

Question

Hey, 
 I am developing a VAF that I would like to replace an existing file with a new file. I am using the below code but I am having some issues. 
 I firstly Check out the existing document (ReplacePDF) I am calling GetFilesForModificationInEventHandler, then calling ReplaceFiles and finally Check in the document. 
 The file newObjectSourceFiles is the new file that I want to replace. 
 
 var newObjVer = env.Vault.ObjectOperations.CheckOut(ReplacePDF.ObjVer.ObjID); env.Vault.ObjectFileOperations.GetFilesForModificationInEventHandler(newObjVer.ObjVer); 
 env.ObjVerEx.ReplaceFiles(newObjectSourceFiles); env.Vault.ObjectOperations.CheckIn(newObjVer.ObjVer);

Thank you

var objVerEx = new ObjVerEx(env.Vault, ReplacePDF.ObjVer);
var b = objVerEx.StartRequireCheckedOut();
objVerEx.ReplaceFiles(newObjectSourceFiles);
objVerEx.EndRequireCheckedOut(b, env.CurrentUserID); 
 In that case you need to get a new ObjVerEx representing the object you want to work with, and operate on that.

ARGH! 
 Sorry, of course. 
 If you're using ObjVerEx then you must call SaveProperties to persist the changes to the server: 
 var objVerEx = new ObjVerEx(env.Vault, ReplacePDF.ObjVer);
var b = objVerEx.StartRequireCheckedOut();
objVerEx.ReplaceFiles(newObjectSourceFiles); //Replace the file 

// These only change IN MEMORY.
objVerEx.SetWorkflowState("WF.HsqeWorkflow", 132); //Change the wokflow 
objVerEx.SetProperty("PD.Company", MFDataType.MFDatatypeMultiSelectLookup, 673); //Set up a property

// Save all changes to the server.
objVerEx.SaveProperties();
objVerEx.CheckIn(); //Check In the object
