  • How do I serialize/deserialize a NHibernate entity that has references to other objects?

    - by Daniel T.
    I have two NHibernate-managed entities that have a bi-directional one-to-many relationship: public class Storage { public virtual string Name { get; set; } public virtual IList<Box> Boxes { get; set; } } public class Box { public virtual string Box { get; set; } [DoNotSerialize] public virtual Storage ParentStorage { get; set; } } A Storage can contain many Boxes, and a Box always belongs in a Storage. I want to edit a Box's name, so I send it to the client using JSON. Note that I don't serialize ParentStorage because I'm not changing which storage it's in. The client edits the name and sends the Box back as JSON. The server deserializes it back into a Box entity. Problem is, the ParentStorage property is null. When I try to save the Box to the database, it updates the name, but also removes the relationship to the Storage. How do I properly serialize and deserialize an entity like a Box, while keeping the JSON data size to a minimum?

  • ANDROID IF/ELSE FAILS CONTINUES TO EXECUTE JSON

    - by Keith Cesar Haizlett
    I am trying to create a Registration app with JSON to connect and post to MYSQL database. I created the following IF/ELSE statements to check for vacant input boxes, password match, and correct email characters before allowing it to be entered into the DATABASE. The code continues to execute the JSON posting even after the passwords don't match , invalid email characters are entered , and vacant text boxes are submitted. Why is it not returning and continuing to execute the JSON code? try { if (!inputEmail.getText().toString().matches("[a-zA-Z0-9._-]+@[a-z]+.[a-z]+") && email.length() > 0) { Toast.makeText(getApplicationContext(), "Enter Valid Email Address", Toast.LENGTH_LONG).show(); return; } else if(name.equals("") || email.equals("")|| password.equals("")||check.equals("")) { Toast.makeText(getApplicationContext(), "Field Vaccant", Toast.LENGTH_LONG).show(); return; } // check if both password matches else if(!password.equals(checkpass)) { Toast.makeText(getApplicationContext(), "Password does not match", Toast.LENGTH_LONG).show(); return; } if (json.getString(KEY_SUCCESS) != null) { registerErrorMsg.setText(""); String res = json.getString(KEY_SUCCESS); if(Integer.parseInt(res) == 1){ // user successfully registred // Store user details in SQLite Database DatabaseHandler db = new DatabaseHandler(getApplicationContext()); JSONObject json_user = json.getJSONObject("user"); // Clear all previous data in database userFunction.logoutUser(getApplicationContext()); db.addUser(json_user.getString(KEY_NAME), json_user.getString(KEY_EMAIL), json.getString(KEY_UID), json_user.getString(KEY_CREATED_AT)); // Launch Dashboard Screen Intent dashboard = new Intent(getApplicationContext(), DashboardActivity.class); // Close all views before launching Dashboard dashboard.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(dashboard); // Close Registration Screen finish(); }else{ // Error in registration registerErrorMsg.setText("User already Registered"); } } } catch (JSONException e) { } } });

  • Session variables not getting set but only in Internet Explorer and not on all machines

    - by gaoshan88
    Logging into a site I'm working on functions as expected on my local machine but fails on the remote server but ONLY in Internet Explorer. The kicker is that it works in IE locally, just not on the remote machine. What in the world could cause this? I have stepped through the code on the remote machine and can see the entered login values being checked in the database, they are found and then a login function is called. This sets two $_SESSION variables and redirects to the main admin page. However, in IE only (and not when run on local machine... this is key) the $_SESSION variables are not present by the time you get to the main admin page. var_dump($_SESSION) gives me what I expect on every browser when I am running this in my local environment and in every browser except IE 6, 7 and 8 when run on the remote server (where I get a null value as if nothing has been set for $_SESSION). This really has me stumped so any advice is appreciated. For an example... in IE, run locally, var_dump gives me: array 'Username' => string 'theusername' length=11 'UserID' => string 'somevalue' length=9 Run on the remote server (IE only... works fine in other browsers) var_dump gives me: array(0){} Code: $User = GetUser($Username, $Password); if ($User->UserID <> "") { // this works so we call Login()... Login($User); // this also works and gives expected results. on to redirect... header("Location: index.php"); // a var_dump at index.php shows that there is no session data at all in IE, remotely. } else { header("Location: login.php"); } function Login($data) { $_SESSION['Username'] = $data->Username; $_SESSION['UserID'] = $data->UserID; // a var dump here gives the expected data in every browser }

  • UITableView not getting populated with sqlite database column

  • SQL putting two single quotes around datetime fields and fails to insert record

    - by user82613
    I am trying to INSERT into an SQL database table, but it doesn't work. So I used the SQL server profiler to see how it was building the query; what it shows is the following: declare @p1 int set @p1=0 declare @p2 int set @p2=0 declare @p3 int set @p3=1 exec InsertProcedureName @ConsumerMovingDetailID=@p1 output, @UniqueID=@p2 output, @ServiceID=@p3 output, @ProjectID=N'0', @IPAddress=N'66.229.112.168', @FirstName=N'Mike', @LastName=N'P', @Email=N'[email protected]', @PhoneNumber=N'(254)637-1256', @MobilePhone=NULL, @CurrentAddress=N'', @FromZip=N'10005', @MoveInAddress=N'', @ToZip=N'33067', @MovingSize=N'1', @MovingDate=''2009-04-30 00:00:00:000'', /* Problem here ^^^ */ @IsMovingVehicle=0, @IsPackingRequired=0, @IncludeInSaveologyPlanner=1 select @p1, @p2, @p3 As you can see, it puts a double quote two pairs of single quotes around the datetime fields, so that it produces a syntax error in SQL. I wonder if there is anything I must configure somewhere? Any help would be appreciated. Here is the environment details: Visual Studio 2008 .NET 3.5 MS SQL Server 2005 Here is the .NET code I'm using.... //call procedure for results strStoredProcedureName = "usp_SMMoverSearchResult_SELECT"; Database database = DatabaseFactory.CreateDatabase(); DbCommand dbCommand = database.GetStoredProcCommand(strStoredProcedureName); dbCommand.CommandTimeout = DataHelper.CONNECTION_TIMEOUT; database.AddInParameter(dbCommand, "@MovingDetailID", DbType.String, objPropConsumer.ConsumerMovingDetailID); database.AddInParameter(dbCommand, "@FromZip", DbType.String, objPropConsumer.FromZipCode); database.AddInParameter(dbCommand, "@ToZip", DbType.String, objPropConsumer.ToZipCode); database.AddInParameter(dbCommand, "@MovingDate", DbType.DateTime, objPropConsumer.MoveDate); database.AddInParameter(dbCommand, "@PLServiceID", DbType.Int32, objPropConsumer.ServiceID); database.AddInParameter(dbCommand, "@FromAreaCode", DbType.String, pFromAreaCode); database.AddInParameter(dbCommand, "@FromState", DbType.String, pFromState); database.AddInParameter(dbCommand, "@ToAreaCode", DbType.String, pToAreaCode); database.AddInParameter(dbCommand, "@ToState", DbType.String, pToState); DataSet dstSearchResult = new DataSet("MoverSearchResult"); database.LoadDataSet(dbCommand, dstSearchResult, new string[] { "MoverSearchResult" });

  • XmlSerializer 'forgetting' my namespace

    - by Michel
    Hi, i have to create an XML file with all the elements prefixed, like this: <ps:Request num="123" xmlns:ps="www.ladieda.com"> <ps:ClientId>5566</ps:ClientId> <ps:Request> When i serialize my object, c# is smart and does this: <Request num="123" xmlns="www.ladieda.com"> <ClientId>5566</ClientId> <Request> That is good, because the ps: is not necessary. But is there a way to force C# to serialize all the prefixes? My serialize code is this (for incoming object pObject): String XmlizedString = null; MemoryStream memoryStream = new MemoryStream(); XmlSerializer xs = new XmlSerializer(pObject.GetType()); XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8); xs.Serialize(xmlTextWriter, pObject); memoryStream = (MemoryStream)xmlTextWriter.BaseStream; XmlizedString = UTF8ByteArrayToString(memoryStream.ToArray()); return XmlizedString; private String UTF8ByteArrayToString(Byte[] characters) { UTF8Encoding encoding = new UTF8Encoding(); String constructedString = encoding.GetString(characters); return (constructedString); }

  • I am using a regex snippet query string path

    - by Shelby Poston
    Using the following to load images base on two ids one is the and bookid and the out is the client. My folder structures is this. root path = flipbooks subfolders under flipbooks are books and clients in subfolder books I have and .net page title tablet. the tablet code behind checks the bookid of client and render a the tablet page with images in a flipbook fashion. because we have over 15000 records and flipbooks already created and stored in the database. I don't move the client folder under the books subfolders. I need the code below to get to the client subfolder in the query string and help to change this would be helpful. The result now is http://www.somewebsite.com/books/client/images/someimage1.jpg[^] I need the results to be http://www.somewebsite.com/client/images/someimage1.jpg[^]. I tried moving the tablet.aspx file to the root flipbooks and it works but i have provide a user name and password each time. This need to be access by the public and my root is protected. Don't want to have to change permission. I am trying to remove the /books function getParameterByName(name) { var results = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search); return results ? decodeURIComponent(results[1].replace(/\+/g, ' ')) : null; } Thanks Mission Critical

  • WPF validation on Enter Key Up

    I'm trying to validate a UI change when Enter key is pressed. The UI element is a textbox, which is data binded to a string. My problem is that the data binding hasn't updated TestText when Enter key is Up.

  • Type casting in C++ by detecting the current 'this' object type

    - by Elroy
    My question is related to RTTI in C++ where I'm trying to check if an object belongs to the type hierarchy of another object. The BelongsTo() method checks this. I tried using typeid, but it throws an error and I'm not sure about any other way how I can find the target type to convert to at runtime. #include <iostream> #include <typeinfo> class X { public: // Checks if the input type belongs to the type heirarchy of input object type bool BelongsTo(X* p_a) { // I'm trying to check if the current (this) type belongs to the same type // hierarchy as the input type return dynamic_cast<typeid(*p_a)*>(this) != NULL; // error C2059: syntax error 'typeid' } }; class A : public X { }; class B : public A { }; class C : public A { }; int main() { X* a = new A(); X* b = new B(); X* c = new C(); bool test1 = b->BelongsTo(a); // should return true bool test2 = b->BelongsTo(c); // should return false bool test3 = c->BelongsTo(a); // should return true } Making the method virtual and letting derived classes do it seems like a bad idea as I have a lot of classes in the same type hierarchy. Or does anybody know of any other/better way to the do the same thing? Please suggest.

  • CRM 2011 - Set/Retrieve work hours programmatically

    - by Philip Rich
    I am attempting to retrieve a resources work hours to perform some logic I require. I understand that the CRM scheduling engine is a little clunky around such things, but I assumed that I would be able to find out how the working hours were stored in the DB eventually... So a resource has associated calendars and those calendars have associated calendar rules and inner calendars etc. It is possible to look at the start/end and frequency of aforementioned calendar rules and query their codes to work out whether a resource is 'working' during a given period. However, I have not been able to find the actual working hours, the 9-5 shall we say in any field in the DB. I even tried some SQL profiling while I was creating a new schedule for a resource via the UI, but the results don't show any work hours passing to SQL. For those with the patience the intercepted SQL statement is below:- EXEC Sp_executesql N'update [CalendarRuleBase] set [ModifiedBy]=@ModifiedBy0, [EffectiveIntervalEnd]=@EffectiveIntervalEnd0, [Description]=@Description0, [ModifiedOn]=@ModifiedOn0, [GroupDesignator]=@GroupDesignator0, [IsSelected]=@IsSelected0, [InnerCalendarId]=@InnerCalendarId0, [TimeZoneCode]=@TimeZoneCode0, [CalendarId]=@CalendarId0, [IsVaried]=@IsVaried0, [Rank]=@Rank0, [ModifiedOnBehalfBy]=NULL, [Duration]=@Duration0, [StartTime]=@StartTime0, [Pattern]=@Pattern0 where ([CalendarRuleId] = @CalendarRuleId0)', N'@ModifiedBy0 uniqueidentifier,@EffectiveIntervalEnd0 datetime,@Description0 ntext,@ModifiedOn0 datetime,@GroupDesignator0 ntext,@IsSelected0 bit,@InnerCalendarId0 uniqueidentifier,@TimeZoneCode0 int,@CalendarId0 uniqueidentifier,@IsVaried0 bit,@Rank0 int,@Duration0 int,@StartTime0 datetime,@Pattern0 ntext,@CalendarRuleId0 uniqueidentifier', @ModifiedBy0='EB04662A-5B38-E111-9889-00155D79A113', @EffectiveIntervalEnd0='2012-01-13 00:00:00', @Description0=N'Weekly Single Rule', @ModifiedOn0='2012-03-12 16:02:08', @GroupDesignator0=N'FC5769FC-4DE9-445d-8F4E-6E9869E60857', @IsSelected0=1, @InnerCalendarId0='3C806E79-7A49-4E8D-B97E-5ED26700EB14', @TimeZoneCode0=85, @CalendarId0='E48B1ABF-329F-425F-85DA-3FFCBB77F885', @IsVaried0=0, @Rank0=2, @Duration0=1440, @StartTime0='2000-01-01 00:00:00', @Pattern0=N'FREQ=WEEKLY;INTERVAL=1;BYDAY=SU,MO,TU,WE,TH,FR,SA', @CalendarRuleId0='0A00DFCF-7D0A-4EE3-91B3-DADFCC33781D' The key parts in the statement are the setting of the pattern:- @Pattern0=N'FREQ=WEEKLY;INTERVAL=1;BYDAY=SU,MO,TU,WE,TH,FR,SA' However, as mentioned, no indication of the work hours set. Am I thinking about this incorrectly or is CRM doing something interesting around these work hours? Any thoughts greatly appreciated, thanks.

  • How to return array of C++ objects from a PHP extension

    - by John Factorial
    I need to have my PHP extension return an array of objects, but I can't seem to figure out how to do this. I have a Graph object written in C++. Graph.getNodes() returns a std::map<int, Node*>.

What am I doing wrong?

  • Problem with loading a PNG image in JApplet.

    - by Bruce
    Hi there, I'm trying to load a PNG image from JAR file when running JApplet. The file is, I think, loaded properly - there are no errors. However it is not displayed. img.png is placed in the same directory as MainClass.java file. Here is the code: InputStream imageURL = this.getClass().getResourceAsStream("img.png" ); byte[] bytes = null; try {bytes = new byte[imageURL.available()]; System.out.println(imageURL.available()); imageURL.read(bytes);} catch(Exception e) {System.out.println("bleah");} Image image = Toolkit.getDefaultToolkit().createImage(bytes); Image imageScaled = me.getScaledInstance( 100, 150, Image.SCALE_SMOOTH ); jLabel6 = new javax.swing.JLabel( new ImageIcon( imageScaled) ); and the HTML exerpt: <APPLET codebase="classes" code="myapplet/MainClass.class" archive ="LittleApplet.jar" width=700 height=500> The image, as I wrote, is probably read, but not displayed in JLabel. What am I missing/doing wrong? Thanks in advance for the reply!

  • Sending one record from cursor to another function Postgres

    - by PylonsN00b
    FYI: I am completely new to using cursors... So I have one function that is a cursor: CREATE FUNCTION get_all_product_promos(refcursor, cursor_object_id integer) RETURNS refcursor AS ' BEGIN OPEN $1 FOR SELECT * FROM promos prom1 JOIN promo_objects ON (prom1.promo_id = promo_objects.promotion_id) WHERE prom1.active = true AND now() BETWEEN prom1.start_date AND prom1.end_date AND promo_objects.object_id = cursor_object_id UNION SELECT prom2.promo_id FROM promos prom2 JOIN promo_buy_objects ON (prom2.promo_id = promo_buy_objects.promo_id) LEFT JOIN promo_get_objects ON prom2.promo_id = promo_get_objects.promo_id WHERE (prom2.buy_quantity IS NOT NULL OR prom2.buy_quantity > 0) AND prom2.active = true AND now() BETWEEN prom2.start_date AND prom2.end_date AND promo_buy_objects.object_id = cursor_object_id; RETURN $1; END; ' LANGUAGE plpgsql; SO then in another function I call it and need to process it: ... --Get the promotions from the cursor SELECT get_all_product_promos('promo_cursor', this_object_id) updated := FALSE; IF FOUND THEN --Then loop through your results LOOP FETCH promo_cursor into this_promotion --Preform comparison logic -this is necessary as this logic is used in other contexts from other functions SELECT * INTO best_promo_results FROM get_best_product_promos(this_promotion, this_object_id, get_free_promotion, get_free_promotion_value, current_promotion_value, current_promotion); ... SO the idea here is to select from the cursor, loop using fetch (next is assumed correct?) and put the record fetched into this_promotion. Then send the record in this_promotion to another function. I can't figure out what to declare the type of this_promotion in get_best_product_promos. Here is what I have: CREATE OR REPLACE FUNCTION get_best_product_promos(this_promotion record, this_object_id integer, get_free_promotion integer, get_free_promotion_value numeric(10,2), current_promotion_value numeric(10,2), current_promotion integer) RETURNS... It tells me: ERROR: plpgsql functions cannot take type record OK first I tried: CREATE OR REPLACE FUNCTION get_best_product_promos(this_promotion get_all_product_promos, this_object_id integer, get_free_promotion integer, get_free_promotion_value numeric(10,2), current_promotion_value numeric(10,2), current_promotion integer) RETURNS... Because I saw some syntax in the Postgres docs showed a function being created w/ a input parameter that had a type 'tablename' this works, but it has to be a tablename not a function :( I know I am so close, I was told to use cursors to pass records around. So I studied up. Please help.

  • error while updating a database in ASP.NET

    - by Viredae
    I am having trouble updating an SQL database, the problem is not that it doesn't update at all, but that particular parameters are being updated while the others are not. here is the code for updating the parameters: string EditRequest = "UPDATE Requests SET Description = @Desc, BJustif = @Justif, Priority = @Priority, Requested_System = @Requested, Request_Status = @Stat WHERE"; EditRequest += " Req_ID=@ID"; SqlConnection Submit_conn = new SqlConnection(WebConfigurationManager.ConnectionStrings["DBConn"].ConnectionString); SqlCommand Submit_comm = new SqlCommand(EditRequest, Submit_conn); Submit_comm.Parameters.AddWithValue("@ID", Request.QueryString["reqid"]); Submit_comm.Parameters.AddWithValue("@Desc", DescBox.Text); Submit_comm.Parameters.AddWithValue("@Justif", JustifBox.Text); Submit_comm.Parameters.AddWithValue("@Priority", PriorityList.SelectedValue); Submit_comm.Parameters.AddWithValue("@Requested", RelatedBox.Text); Submit_comm.Parameters.AddWithValue("@Stat", 1); Submit_conn.Open(); Submit_comm.ExecuteNonQuery(); Submit_comm.Dispose(); Submit_comm = null; Submit_conn.Close(); get_Description(); Page.ClientScript.RegisterStartupScript(this.GetType(), "Refresh", "ReloadPage();", true); this function is called by a button on a pop-up form which shows the parameters content that is being changed in a text box which is also used to submit the changes back to the database, but when I press submit, the parameters which are displayed on the form don't change, I can't find any problem wit the code, even though I've compared it to similar code which is working fine. In case you need to, here is one of the text boxes I'm using to display and edit the content: <asp:TextBox ID="JustifBox" TextMode="MultiLine" runat="server" Width="250" Height="50"></asp:TextBox> What exactly is wrong with the code?

  • Foreign key relationships in Entity Framework

    - by Anders Svensson
    I'm trying to add an object created from Entity Data Model classes. I have a table called Users, which has turned into a User EDM class. And I also have a table Pages, which has become a Page EDM class. These tables have a foreign key relationship, so that each page is associated with many users. Now I want to be able to add a page, but I can't get how to do it. I get a nullreference exception on Users below. I'm still rather confused by all this, so I'm sure it's a simple error, but I just can't see how to do it. Also, by the way, the compiler requires that I set PageID in the object initializer, even though this field is set to be an automatic id in the table. Am I doing it right just setting it to 0, expecting it to be updated automatically in the table when saved, or how should I do that? Any help appreciated! The method in question: private Page GetPage(User currentUser) { string url = _request.ServerVariables["url"].ToLower(); var userPages = from p in _context.PageSet where p.Users.UserID == currentUser.UserID select p; var existingPage = userPages.FirstOrDefault(e => e.Url == url); //Could be combined with above, but hard to read? if (existingPage != null) return existingPage; Page page = new Page() { Count = 0, Url = _request.ServerVariables["url"].ToLower(), PageID = 0, //Only initial value, changed later? }; _context.AddToPageSet(page); page.Users.UserID = currentUser.UserID; //Here's the problem... return page; }

  • Move selected e-mails to Personal inbox Folders Files

    - by kasunmit
    Hi, I am creating sub folders inside the inbox folder using following code. private void btnCreate_Click(object sender, EventArgs e) { if (string.IsNullOrEmpty(txtInboxFolderName.Text.Trim().ToString())) { MessageBox.Show("Enter name of the folder", "Null value", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); txtInboxFolderName.Focus(); return; } else { CreateNewInboxFolder(); } } private void CreateNewInboxFolder() { try { string folderName = txtInboxFolderName.Text.ToString(); OutLook._Application olApp = new OutLook.ApplicationClass(); OutLook._NameSpace olNs = olApp.GetNamespace("MAPI"); OutLook.MAPIFolder oInbox = olNs.GetDefaultFolder(OutLook.OlDefaultFolders.olFolderInbox); OutLook.Folders oFolders = oInbox.Folders; OutLook.MAPIFolder oInboxFolders = oFolders.Add(folderName, OutLook.OlDefaultFolders.olFolderInbox); MessageBox.Show("Folder " + oInboxFolders.Name + " is Created", "Create inbox folder", MessageBoxButtons.OK, MessageBoxIcon.Information); } catch (Exception) { MessageBox.Show("Folder name: " + txtInboxFolderName.Text +" is already created" + "\nPlease enter different folder name", "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); txtInboxFolderName.Focus(); } } From the above code I can create sub folder inside the Inbox folder. Then what I need to do is save the e-mail into that created folder. Please help me to do it. I think we can import those folder names to a separate form and select one from there, then I can save e-mails (e-mail datails is in the data grid and I need to save them to new folder) Please help me with the code. I am very confused and I'm not sure how to do it.

  • How to use the FindControl function to find a dynamically generated control?

    - by Abe Miessler
    I have a PlaceHolder control inside of a ListView that I am using to render controls from my code behind. The code below adds the controls: TextBox tb = new TextBox(); tb.Text = quest.Value; tb.ID = quest.ShortName.Replace(" ", ""); ((PlaceHolder)e.Item.FindControl("ph_QuestionInput")).Controls.Add(tb); I am using the following code to retrieve the values that have been entered into the TextBox: foreach (ListViewDataItem di in lv_Questions.Items) { int QuestionId = Convert.ToInt32(((HiddenField)di.FindControl("hf_QuestionId")).Value); Question quest = dc.Questions.Single(q => q.QuestionId == QuestionId); TextBox tb = ((TextBox)di.FindControl(quest.ShortName.Replace(" ",""))); //tb is always null! } But it never finds the control. I've looked at the source code for the page and the control i want has the id: ctl00_cphContentMiddle_lv_Questions_ctrl0_Numberofacres For some reason when I look at the controls in the ListViewDataItem it has the ClientID: ctl00_cphContentMiddle_lv_Questions_ctrl0_ctl00 Why would it be changing Numberofacres to ctl00? Is there any way to work around this? UPDATE: Just to clarify, I am databinding my ListView in the Page_Init event. I then create the controls in the ItemBound event for my ListView. But based on what @Womp and MSDN are saying the controls won't actually be created until after the Load event (which is after the Page_Init event) and therefore are not in ViewState? Does this sound correct? If so am I just SOL when it comes to retrieving the values in my dynamic controls from my OnClick event?

  • Best way to determine variable type and treat each one differently in F#

    - by James Black
    I have a function that will create a select where clause, but right now everything has to be a string. I would like to look at the variable passed in and determine what type it is and then treat it properly. For example, numeric values don't have single quotes around them, option type will either be null or have some value and boolean will actually be zero or one. member self.BuildSelectWhereQuery (oldUser:'a) = let properties = List.zip oldUser.ToSqlValuesList sqlColumnList let init = false, new StringBuilder() let anyChange, (formatted:StringBuilder) = properties |> Seq.fold (fun (anyChange, sb) (oldVal, name) -> match(anyChange) with | true -> true, sb.AppendFormat(" AND {0} = '{1}'", name, oldVal) | _ -> true, sb.AppendFormat("{0} = '{1}'", name, oldVal) ) init formatted.ToString() Here is one entity: type CityType() = inherit BaseType() let mutable name = "" let mutable stateId = 0 member this.Name with get() = name and set restnameval=name <- restnameval member this.StateId with get() = stateId and set stateidval=stateId <- stateidval override this.ToSqlValuesList = [this.Name; this.StateId.ToString()] So, if name was some other value besides a string, or stateId can be optional, then I have two changes to make: How do I modify ToSqlValuesList to have the variable so I can tell the variable type? How do I change my select function to handle this? I am thinking that I need a new function does the processing, but what is the best FP way to do this, rather than using something like typeof?
