    - by user363295
    Hi all. I'm quite new in programming .I wrote the below code in order to prompt the user for a password to encrypting a file, But it just work when the length of password is 8, What can I do on order to accepting any number of characters for the password? string pass = textBox2.Text.ToString(); string password = @"" + pass + ""; UnicodeEncoding UE = new UnicodeEncoding(); byte[] key = UE.GetBytes(password); FileStream fsCrypt = new FileStream(@"c:\\users\\new", FileMode.Create); name = fsCrypt.Name; RijndaelManaged RMCrypto = new RijndaelManaged(); CryptoStream cs = new CryptoStream(fsCrypt, RMCrypto.CreateEncryptor(key, key), CryptoStreamMode.Write); FileStream fsIn = new FileStream(filename, FileMode.Open); int data; while ((data = fsIn.ReadByte()) != -1) cs.WriteByte((byte)data);

  • Stringbuilder problem creating dynamic links

    - by wali
    Hi all, I'm having an issue creating a link like "<a href="javascript:window.open('www.microsoft.com');">Visit Microsoft</a> using stringbuilder. I am adding html to a panel dynamically and I am trying to create a popup link. The problem is that for some reason the link gets "mixed up". For example: Dim s As String sb.Append("<A HREF='javascript:void(0)' onclick='window.open(") sb.Append("'") sb.Append("Match.aspx?MatchID=") sb.Append(mt.MatchID) sb.Append("&batchid=") sb.Append(mb.batchID) sb.Append("')>") sb.Append("Match</A>") gives an output of : <a match.aspx?matchid="28840&amp;batchid=26596')" onclick="window.open(" href="javascript:void(0)">Match</a> I have no clue what I'm doing wrong, it even does this kind of crap for a regular string! Please help!

  • Javascript calls to an Ajax WebMethod. How to get multiple output params returned?

    - by George
    OK, I know how to call a simple old fashion asmx webservice webthod that returns a single value as a function return result. But what if I want to return multiple output params? My current approach is to separate the params by a dividing character and parse them on teh client. Is there a better way. Here's how I return a single function result. How do I return multiple output values? <asp:ScriptManager ID="ScriptManager1" runat="server"> <Services> <asp:ServiceReference Path="WebService.asmx" /> </Services> function CallHelloWebMethod() { WebService.Hello(OnComplete1, OnTimeOut, OnError); } function OnComplete1(arg) { alert(arg); } function OnTimeOut(arg) { } <WebMethod()> Public Function Hello(ByVal x As String) As String Return "Hello " & x End Function

  • Find Methods in a c# File programmatically

    - by sajad
    Hi Friends, I want to write a code to search for method defination and methods called in a c# file. So obviously my pattern should search for text like 1.public void xyz(blahtype blahvalue); 2.string construct = SearchData(blahvalue); Has anyone done similar to this, is Regex helpful in this case. if yes provide me the pattern. Any other workarounds. I dont know reflection(will it help in my case) Thanks, you guys gave it a try, i did not know this wud be so complex. All i wanted to do was suppose i have method like this public method1(int val) { method2(); method3(); } void method2(int val2) { method4() } i wanted to construct a string as Method1:Method2:method4 and Method1:Method3.... I guess its really complex

  • GetProperties() to return all properties for an interface inheritance hierarchy

    - by sduplooy
    Assuming the following hypothetical inheritance hierarchy: public interface IA { int ID { get; set; } } public interface IB : IA { string Name { get; set; } } Using reflection and making the following call: typeof(IB).GetProperties(BindingFlags.Public | BindingFlags.Instance) will only yield the properties of interface IB, which is "Name". If we were to do a similar test on the following code, public abstract class A { public int ID { get; set; } } public class B : A { public string Name { get; set; } } the call typeof(B).GetProperties(BindingFlags.Public | BindingFlags.Instance) will return an array of PropertyInfo objects for "ID" and "Name". Is there an easy way to find all the properties in the inheritance hierarchy for interfaces as in the first example?

  • asp.net mvc custom routes with multiple submit buttons

    - by dangerisgo
    So I have a custom route as such: routes.MapRoute( "Wizard", // Route name "Wizard/{page}", // URL with parameters new { controller = "Wizard", action = "Index" } // Parameter defaults ); and have the following on my View: <% Html.BeginForm("Continue", "Wizard"); %> <input type="submit" value="Continue" name="Continue" /> <% Html.EndForm(); %> In which I want to call this function: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Continue(string Number, string Rev) { (...) } but in turn when that button is pressed always calls the postback Index rather than the one I want. If I remove the custom route, it calls my function, but what I want to be displayed in the address bar is: localhost:xxxx/Wizard/1 where the number at the end is the page (div shown) of the wizard either 1, 2, 3, or 4. So is there something I'm missing or can it not be done? Thanks.

  • dbms_xmlschema fail to validate with complexType

    - by Andrew
    Preface: This works on one Oracle 11gR1 (Solaris 64) database and not on a second and we can't figure out the difference between the two databases. Somehow the complexType causes the validation to fail with this error: ORA-31154: invalid XML document ORA-19202: Error occurred in XML processing LSX-00200: element "shiporder" not empty ORA-06512: at "SYS.XMLTYPE", line 354 ORA-06512: at line 13 But the schema is valid (passes this online test: http://www.xmlme.com/Validator.aspx) -- Cleanup any existing schema begin dbms_xmlschema.deleteschema('shiporder.xsd',dbms_xmlschema.DELETE_CASCADE); end; -- Define the problem schema (adapted from http://www.w3schools.com/schema/schema_example.asp) begin dbms_xmlschema.registerSchema('shiporder.xsd','<?xml version="1.0" encoding="ISO-8859-1" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="shiporder"> <xs:complexType> <xs:sequence> <xs:element name="orderperson" type="xs:string"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema>',owner=>'SCOTT'); end; -- Attempt to validate declare bbb xmltype; begin bbb := XMLType('<?xml version="1.0" encoding="ISO-8859-1"?> <shiporder xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="shiporder.xsd"> <orderperson>John Smith</orderperson> </shiporder>'); XMLType.schemaValidate(bbb); end; Now if I gut the schema definition and leave only a string in the XML then the validation passes: begin dbms_xmlschema.deleteschema('shiporder.xsd',dbms_xmlschema.DELETE_CASCADE); end; begin dbms_xmlschema.registerSchema('shiporder.xsd','<?xml version="1.0" encoding="ISO-8859-1" ?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="shiporder" type="xs:string"/> </xs:schema>',owner=>'SCOTT'); end; DECLARE xml XMLTYPE; BEGIN xml := XMLTYPE('<?xml version="1.0" encoding="ISO-8859-1"?> <shiporder xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="shiporder.xsd"> John Smith </shiporder>'); XMLTYPE.schemaValidate(xml); END;

  • Sync Framework Considerations for Smart Client app

    - by DarkwingDuck
    Microsoft Sync Framework with SQL 2005? Is it possible? It seems to hint that the OOTB providers use SQL2008 functionality. I'm looking for some quick wins in relation to a sync project. The client app will be offline for a number of days. There will be a central server that MUST be SQL Server 2005. I can use .net 3.5. Basically the client app could go offline for a week. When it comes back online it needs to sync its data. But the good thing is that the data only needs to push to the server. The stuff that syncs back to the client will just be lookup data which the client never changes. So this means I don't care about sync collisions. To simplify the scenario for you, this smart client goes offline and the user surveys data about some observations. They enter the data into the system. When the laptop is reconnected to the network, it syncs back all that data to the server. There will be other clients doing the same thing too, but no one ever touches each other's data. Then there are some reports on the server for viewing the data that has been pushed to the server. This also needs to use ClickOnce. My biggest concern is that there is an interim release while a client is offline. This release might require a new field in the database, and a new field to fill in on the survey. Obviously that new field will be nullable because we can't update old data, that's fine to set as an assumption. But when the client connects up and its local data schema and the server schema don't match, will sync framework be able to handle this? After the data is pushed to the server it is discarded locally. Hope my problem makes sense.

  • Alternatives to nested interfaces (not possible in C#)

    - by ericdes
    I'm using interfaces in this case mostly as a handle to an immutable instance of an object. The problem is that nested interfaces in C# are not allowed. Here is the code: public interface ICountry { ICountryInfo Info { get; } // Nested interface results in error message: // Error 13 'ICountryInfo': interfaces cannot declare types public interface ICountryInfo { int Population { get; } string Note { get; } } } public class Country : ICountry { CountryInfo Info { get; set; } public class CountryInfo : ICountry.ICountryInfo { int Population { get; set; } string Note { get; set; } ..... } ..... } I'm looking for an alternative, anybody would have a solution?

  • Change panel "visible" property on MasterPage from Child pages

    - by Vitor Reis
    I want to show some panel with a label that is located on a MasterPage from inside it's child pages.. I already did the coding on the MasterPage: public class MyMaster : MasterPage { public void ShowPanel(string pMessage) { labelInside.Text = pMessage; myPanel.visible = true; } } Then I make the calls from child pages: public void ShowPanel(string pMessage) { MyMaster masterPage = this.Master as MyMaster; masterPage.ShowPanel(pMessage); } This "works" ok, but it won't show nothing, since I need the page to be "refreshed" in an "ajax-way" like an UpdatePanel, which I can't use because the Trigger is in another page, right? I really need this to work.. even if you have another completely different way to do this, I would appreciate.

  • jsonp cross domain only working in IE

    - by iboeno
    EDIT: At first I thought it wasn't working cross domain at all, now I realize it only works in IE I'm using jQuery to call a web service (ASP.NET .axmx), and trying to us jsonp so that I can call it across different sites. Right now it is working ONLY in IE, but not in Firefox, Chrome, Safari. Also, in IE, a dialog pops up warning "This page is accessing information that is not under its control..." Any ideas? Here is the code: $.ajax({ type: "POST", url: "http://test/TestService.asmx/HelloWorld?jsonp=?", dataType: "jsonp", success: function(data) { alert(data.prop1); }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(XMLHttpRequest.status + " " + textStatus + " " + errorThrown); } }); And the server code is: [ScriptService] public class TestService : System.Web.Services.WebService{ [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public void HelloWorld() { string jsoncallback = HttpContext.Current.Request["jsonp"]; var response = string.Format("{0}({1});", jsoncallback, @"{'prop1' : '" + DateTime.Now.ToString() + "'}"); HttpContext.Current.Response.Write(response); } }

  • Arrays of different types

    - by Tyler
    Hi - Is it possible to have an array that contains two different types of data? I want to have an array that contains a double and also a string. I attempted: ArrayList<double><String> array; But that didn't work. Sorry for the silly question, but it has been a while since I have used something like this.. Can you refresh my memory on how would I declare and populate such an array? And then to take it a step further, I would like to sort the array by the double if possible? Thanks!

  • iphone: accessing the preferences localization file from code

    - by phonecoddy
    I was just facing the following problem and couldn't find a solution for it. Hopefully someone could help. The app I am working on has some preferences, which are using a localization file. Now I want to use labels in my app, which display the exact names, which are used in the localization file for the preferences. But I couldn't find a way to access the information which is stored in Settings.bundle - en.lproj - localizationfile.strings. to make this clear: If you open your preferences for your app, the display shows the localized string of the title and the value of the setting. I need to access the localized string of the title of each preference from my code. Does any know how to do this?

  • [Android] accessing another Activity's preferences

    I have a Login Activity which stores credentials in its own SharedPreferences; then I added two getters for reading them, something like public String getUsername() { return getPreferences(MODE_PRIVATE).getString("#username", null); } but this throws a NPE when I call it like this String mUser = (new Login()).getUsername(); It seems that the Activity cannot read its preferences after a simple contructor call, as if it were in some uncompleted state. I read lots of related topics, but wasn't able to find a solution. Basically, I need to share these credentials among activities in my application

  • LsaAddAccountRights not working for me

    - by SteveL
    Using: Delphi 2010 and the JEDI Windows API and JWSCL I am trying to assign the Logon As A Service privilege to a user using LsaAddAccountRights function but it does not work ie. after the function returns, checking in Group Policy Editor shows that the user still does not have the above mentioned privilege. I'm running the application on Windows XP. Would be glad if someone could point out what is wrong in my code: unit Unit1; interface uses Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls, JwaWindows, JwsclSid; type TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var Form1: TForm1; implementation {$R *.dfm} function AddPrivilegeToAccount(AAccountName, APrivilege: String): DWORD; var lStatus: TNTStatus; lObjectAttributes: TLsaObjectAttributes; lPolicyHandle: TLsaHandle; lPrivilege: TLsaUnicodeString; lSid: PSID; lSidLen: DWORD; lTmpDomain: String; lTmpDomainLen: DWORD; lTmpSidNameUse: TSidNameUse; lPrivilegeWStr: String; begin ZeroMemory(@lObjectAttributes, SizeOf(lObjectAttributes)); lStatus := LsaOpenPolicy(nil, lObjectAttributes, POLICY_LOOKUP_NAMES, lPolicyHandle); if lStatus <> STATUS_SUCCESS then begin Result := LsaNtStatusToWinError(lStatus); Exit; end; try lTmpDomainLen := DNLEN; // In 'clear code' this should be get by LookupAccountName SetLength(lTmpDomain, lTmpDomainLen); lSidLen := SECURITY_MAX_SID_SIZE; GetMem(lSid, lSidLen); try if LookupAccountName(nil, PChar(AAccountName), lSid, lSidLen, PChar(lTmpDomain), lTmpDomainLen, lTmpSidNameUse) then begin lPrivilegeWStr := APrivilege; lPrivilege.Buffer := PChar(lPrivilegeWStr); lPrivilege.Length := Length(lPrivilegeWStr) * SizeOf(Char); lPrivilege.MaximumLength := lPrivilege.Length; lStatus := LsaAddAccountRights(lPolicyHandle, lSid, @lPrivilege, 1); Result := LsaNtStatusToWinError(lStatus); end else Result := GetLastError; finally FreeMem(lSid); end; finally LsaClose(lPolicyHandle); end; end; procedure TForm1.Button1Click(Sender: TObject); begin AddPrivilegeToAccount('Sam', 'SeServiceLogonRight'); end; end.

  • In a bidirectional JPA OneToMany/ManyToOne association, what is meant by "the inverse side of the as

    - by Bytecode Ninja
    In these examples on TopLink JPA Annotation Reference: Example 1-59 @OneToMany - Customer Class With Generics @Entity public class Customer implements Serializable { ... @OneToMany(cascade=ALL, mappedBy="customer") public Set<Order> getOrders() { return orders; } ... } Example 1-60 @ManyToOne - Order Class With Generics @Entity public class Order implements Serializable { ... @ManyToOne @JoinColumn(name="CUST_ID", nullable=false) public Customer getCustomer() { return customer; } ... } It seams to me that the Customer entity is the owner of the association. However, in the explanation for the mappedBy attribute in the same document, it is written that: if the relationship is bidirectional, then set the mappedBy element on the inverse (non-owning) side of the association to the name of the field or property that owns the relationship as Example 1-60 shows. However, if I am not wrong, looks like in the example the mappedBy is actually specified on the owning side of the association, rather than the non-owning side. So my question is basically: In a bidirectional (one-to-many/many-to-one) association, which of the entities is the owner? How can we designate the One side as the owner? How can we designate the Many side as the owner? What is meant by "the inverse side of the association"? How can we designate the One side as the inverse? How can we designate the Many side as the inverse? Thanks in advance.

  • Erlang ODBC parameter query with null parameters

    - by Schlomer
    Is it possible to pass null values to parameter queries? For example Sql = "insert into TableX values (?,?)". Params = [{sql_integer, [Val1]}, {sql_float, [Val2]}]. % Val2 may be a float, or it may be the atom, undefined odbc:param_query(OdbcRef, Sql, Params). Now, of course odbc:param_query/3 is going to complain if Val2 is undefined when trying to match to a sql_float, but my question is... Is it possible to use a parameterized query, such as: Sql = "insert into TableY values (?,?,?,?,?,?,?,?,?)". with any null parameters? I have a use case where I am dumping a large number of real-time data into a database by either inserting or updating. Some of the tables I am updating have a dozen or so nullable fields, and I do not have a guarantee that all of the data will be there. Concatenating a SQL together for each query, checking for null values seems complex, and the wrong way to do it. Having a parameterized query for each permutation is simply not an option. Any thoughts or ideas would be fantastic! Thank you!

  • How can I edit an entity in MVC4 with EF5 which has a unique constraint?

    [HttpPost] public ActionResult Edit(Car car) { if (ModelState.IsValid) { db.Entry(car).State = EntityState.Modified; db.SaveChanges(); return RedirectToAction("Index"); } return View(car); } This is a controller method scaffolded by MCV 4 My "car" entity has a unique field: LicensePlate.

See 'EntityValidationErrors' property for more details. The error is the one raised by my validation, saying it can't edit because there is already a car with that license plate. If anyone could point me in the right direction to fix this, that would be great! I searched but couldn't find anything, so even related posts are welcome!
