Pass parameters from custom menu to reports

I am attempting to create a menu very similar to the 'Reports' menu on the 'Invoices/Memos' form on the 'Contact' form.
I have successfully added the menu button, and populated it with one item (via 'Automation Steps') so that the menu appears with my menu item and successfully launches my report.
My report has a ContactID parameter, as illustrated:
I have a customization created with the following code:
namespace PX.Objects.CR
{
public class ContactMaint_Extension : PXGraphExtension<ContactMaint>
{
public PXAction<Contact> letters;
[PXUIField(DisplayName = "Letters", MapEnableRights = PXCacheRights.Select)]
[PXButton(SpecialType = PXSpecialButtonType.Report)]
protected virtual IEnumerable Letters(PXAdapter adapter, string reportID)
{
PXReportRequiredException ex = null;
Contact contact = Base.Caches[typeof(Contact)].Current as Contact;
var parameters = new Dictionary<string, string>();
parameters["Contact.ContactID"] = contact.ContactID.ToString();
ex = PXReportRequiredException.CombineReport(ex, reportID, parameters);
//this.Save.Press();
if (ex != null) throw ex;
return adapter.Get();
}
}
}
However, the resulting report does not seem to have the Contact.ContactID parameter passed to it.
I have gotten where I am by loosely interpreting the post here.
Could someone help me out? I would appreciate it!

To pass a parameter value to a report you need to use the Parameter name. In your example its just "ContactID" so you can set it like this...
parameters["ContactID"] = contact.ContactID.ToString();
If you need to use non parameter fields by DAC.Field I think you need to add them to Viewer Fields in your report. Then you can use it like you had it (parameters["MyDac.MyFieldName"] = "somevalue").
I had to add viewer fields recently to call a report by non parameter fields. This is the only way I could get that to work. Otherwise the parameters just require the call by parameter name.
Here is an example from Vendor Maintenance calling a vendor report where the report has a parameter named "VendorID":
Dictionary<string, string> parameters = new Dictionary<string, string>();
parameters["VendorID"] = vendor.AcctCD;
throw new PXReportRequiredException(parameters, "AP632500", AP.Messages.BalanceByVendor);
The example I used recently to call a report not using a parameter (using a viewer field) was the shipment confirmation report. It calls multiple shipments which is why a single parameter will not work. It uses the PXReportRequiredException.CombineReport call to append multiple shipments to a single report call/exception. Sample:
//SOShipementEntry.Report(PXAdapter,string)
PXReportRequiredException ex = null;
// Loop on shipments
// ...
parameters["SOShipment.ShipmentNbr"] = order.ShipmentNbr;
// ...
ex = PXReportRequiredException.CombineReport(ex, actualReportID, parameters);
// ...
// End shipments loop
if (ex != null) throw ex;

Can I save the contents of an ObservableCollection so that the list is still intact when I restart my app?

What I want to do is have the user add items to the list. Then when they add an item I need the list to save, so that when the user closes the app and opens it again, the list they've created is still there.
Right now, I can add items to my list, but as soon as i close the app they will be gone.
private static ObservableCollection<ViewModels.ZoneViewModel> Zones = new ObservableCollection<ViewModels.ZoneViewModel>();
public void PopulateListView(string image, string name, string address)
{
if (name != "" && address != "")
{
Zones.Add(new ViewModels.ZoneViewModel { Image = image, Name = name, Address = address });
Application.Current.Properties["zoneslist"] = Zones;
}
}
protected override void OnAppearing()
{
if (Application.Current.Properties.ContainsKey("zoneslist"))
{
// Put the contents of the "zoneslist" key into a variable as a string.
var savedZones = Application.Current.Properties["zoneslist"] as ObservableCollection<ViewModels.ZoneViewModel>;
// Set the listviews' itemssource to the savedzones list.
zonesList.ItemsSource = savedZones;
}
}
Here's the code I use right now, I thought this could work to save it but that doesn't work.
EDIT: So I've tried what #Alessandro Calario suggested and after using json serialization the listview just gives me a ton of empty list items(even though i only added one). But an item is added and is saved, even when the app is closed. Progress, at least, but I'm not quite there yet. Anyone know a solution?
my code:
public void PopulateListView(string image, string name, string address)
{
if (name != "" && address != "")
{
Zones.Add(new ViewModels.ZoneViewModel { Image = image, Name = name, Address = address });
//Serialize to json string
var json = JsonConvert.SerializeObject(Zones);
Application.Current.Properties["zoneslist"] = json;
}
}
protected override void OnAppearing()
{
if (Application.Current.Properties.ContainsKey("zoneslist"))
{
// Put the contents of the "zoneslist" key into a variable as a string.
var savedZones = Application.Current.Properties["zoneslist"] as string; //ObservableCollection<ViewModels.ZoneViewModel>
JsonConvert.DeserializeObject<ObservableCollection<ViewModels.ZoneViewModel>>(savedZones);
// Set the listviews' itemssource to the savedzones list.
zonesList.ItemsSource = savedZones;
}
}

I think you can Serialize your List of Objects to a json String and save it to Application Properties

If using 3rd parties libraries is not a thing for your project I highly recommend you to use Akavache. This is an Async, persistent key-value store.
Once setup is very simple to use.
//To Insert your object
IObservable<Unit> InsertObject<T>(string key, T value, DateTimeOffset? absoluteExpiration = null);
//To Get your object
IObservable<T> GetObject<T>(string key);
where T can be your whole list.
Of course it's a little more than this but trust me just a little. Read the full documentation and hope it fits your needs.

The Application Properties only stores primitive types.
Note: the Properties dictionary can only serialize primitive types for
storage. Attempting to store other types (such as List can
fail silently).
Source: https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/application-class/
Either set it up so you are using the properties as a primitive storage, or go for another local storage mechanism such as Sqlite (a good guide here: https://developer.xamarin.com/guides/xamarin-forms/application-fundamentals/databases/)

Integrating IM applications with outlook 2010/2013

I have implemented the IM application (name is "ContactCardDesktop.exe") as suggested by the link https://msdn.microsoft.com/en-us/library/office/jj900715(v=office.15).aspx
I have done all the registry setting per the article. but there is no call to outlook to IM application for function GetAuthenticationInfo() and GetInterface().
Even not getting the ProcessID at registry location HKCU\Software\IM Providers\ContactCardDesktop.
In outlook logs I am getting errors attached below. I have gone through to many suggestion but didn't get help much.
Please suggest the problem/solution.
Sample code for Application.

Manage/Update Records in ASP.NET With Redis using ServiceStack

I'm coming from a SQL Server background, and experimenting with Redis in .NET using ServiceStack. I don't mean for Redis to be a full replacement for SQL Server, but I just wanted to get a basic idea of how to use it so I could see where we might make good use of it.
I'm struggling with what I think is a pretty basic issue. We have a list of items that are maintained in a couple of different data stores. For the sake of simplicity, assume the definition of the item is basic: an integer id and a string name. I'm trying to do the following:
Store an item
Retrieve an item if we only know its id
Overwrite an existing item if we only know its id
Show all the items for that specific type
And here's some of the code I've put together:
public class DocumentRepositoryRedis
{
private static string DOCUMENT_ID_KEY_BASE = "document::id::";
public IQueryable<Document> GetAllDocuments()
{
IEnumerable<Document> documentsFromRedis;
using (var documents = new RedisClient("localhost").As<Document>())
{
documentsFromRedis = documents.GetAll();
}
return documentsFromRedis.AsQueryable();
}
public Document GetDocument(int id)
{
Document document = null;
using (var redisDocuments = new RedisClient("localhost").As<Document>())
{
var documentKey = GetKeyByID(document.ID);
if (documentKey != null)
document = redisDocuments.GetValue(documentKey);
}
return document;
}
public void SaveDocument(Document document)
{
using (var redisDocuments = new RedisClient("localhost").As<Document>())
{
var documentKey = GetKeyByID(document.ID);
redisDocuments.SetEntry(documentKey, document);
}
}
private string GetKeyByID(int id)
{
return DOCUMENT_ID_KEY_BASE + id.ToString();
}
}
It all seems to work - except for GetAllDocuments. That's returning 0 documents, regardless of how many documents I have stored. What am I doing wrong?

The typed Redis client also gives you access to the non-typed methods - since Redis ultimately doesn't know or care about your object types. So when you use the client.SetEntry() method, it bypasses some of the typed client's features and just stores the object by a key. You'll want to use the client.Store method since it goes ahead and creates a SET in Redis with all the object IDs related to your type. This SET is important because it's what the GetAll method relies on to serve back all the objects to you. The client.Store method does infer the ID automatically so you'll want to play around with it.
You'd change your GetDocument(int id) and SaveDocument(Document document) methods to use the client.GetById(string id) method, and you'd use client.Store(T value) method. You won't need your GetKeyByID() method anymore. I believe your Document object will need an "Id" property for the typed client to infer your object ID.

Save Object back to the database

I am working on a project where I am converting some VB.Net class libraries to C# libraries (mostly to learn C# syntax). My problem is that I cannot get the Save function working.
I am building my object with this:
public static StoreEmployee Create(string LoginId)
{
var emp = new StoreEmployee();
using (var dt = DAC.ExecuteDataTable("usp_ActiveEmployeeSelect",
DAC.Parameter(CN_LoginId, LoginId)))
{
emp.StoreId = Convert.ToString(dt.Rows[0][CN_StoreId]);
emp.FirstName = Convert.ToString(dt.Rows[0][CN_FirstName]);
emp.LastName = Convert.ToString(dt.Rows[0][CN_LastName]);
emp.UserName = Convert.ToString(dt.Rows[0][CN_UserName]);
emp.Role = Convert.ToString(dt.Rows[0][CN_Role]);
emp.Description = Convert.ToString(dt.Rows[0][CN_Description]);
}
return emp;
}
And then creating it with this
private static void FillStoreEmployeeObject(string empLoginId)
{
StoreEmployee.Create(empLoginId);
}
And then trying to use this save function to save the object back to the database:
public override Boolean Save(string LoginId)
{
try
{
int retVal = DAC.ExecuteNonQuery("usp_ActiveEmployeeSave",
DAC.Parameter(CN_LoginId, LoginId),
DAC.Parameter(CN_StoreId, StoreId),
DAC.Parameter(CN_FirstName, FirstName),
DAC.Parameter(CN_UserName, UserName),
DAC.Parameter(CN_Role, Role),
DAC.Parameter(CN_Description, Description));
return true;
}
catch
{
return false;
}
}
I don't get a syntax warning for that but I have revised it many times so I want to make sure that is correct before I move on. Does this look correct? By the way I am trying to call the Save function with this
StoreEmployee.Save(Convert.ToString(Login))
which gives me this error An object reference is required for the non-static field, method, or property However when I mark my function as static my Create function shows errors so I am left very confused.

Save is an instance method.
As the error message states,you need to call it on an existing instance of StoreEmployee (such as the one returned by Create).
