  • Encryption using rijndael

    - 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);

  • Mongoid Embeds_many won't save on nested form

    - by Brandon J McKay
    I've got an embeds_many association I'm trying to set up which I've done successfully before, but I'm trying to do it all in one nested form and I can't figure it out. Let's say we have a pocket model: class Pocket include Mongoid::Document field :title, type: String embeds_many :coins, cascade_callbacks: true end and a Coin Model: class Coin include Mongoid::Document field :name, type: String embedded_in :pocket end in my form for the pocket, I'm using: = f.fields_for @pocket.coins do |coin| = coin.text_field :name My controller is the default scaffolded controller. When I use the console, it saves fine and I can see the new pocket and coin I've created. But when I try to create or update a coin from the form, the pocket saves but the coin remains unchanged. What am I missing here?

  • dbms_xmlschema fail to validate with complexType

    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.

  • VB.NET, make a function with return type generic ?

  • Why can I not add a set accessor to an overriden property?

    - by Svish
    In a base class I have this property: public virtual string Text { get { return text; } } I want to override that and return a different text, but I would also like to be able to set the text, so I did this: public override string Text { get { return differentText; } set { differentText = value; } } This however does not work. I get a red squiggly under set saying that I can not override because it does not have a set accessor. Why is this aproblem? What should I do?

  • 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

  • Authorization in a more purely OOP style...

    - by noblethrasher
    I've never seen this done but I had an idea of doing authorization in a more purely OO way. For each method that requires authorization we associate a delegate. During initialization of the class we wire up the delegates so that they point to the appropriate method (based on the user's rights). For example: class User { private deleteMemberDelegate deleteMember; public StatusMessage DeleteMember(Member member) { if(deleteMember != null) { deleteMember(member); } } //other methods defined similarly... User(string name, string password) //cstor. { //wire up delegates based on user's rights. //Thus we handle authentication and authorization in the same method. } } This way the client code never has to explictly check whether or not a user is in a role, it just calls the method. Of course each method should return a status message so that we know if and why it failed. Thoughts?

  • ListView not showing up in fragment

    When I insert a listview in a fragment in my application, it doesn't show up after I populate it with items. In fact, the application crashes due to a NullPointerException. Can anybody help me?

The fragment gets inflated properly, but when I try to add items to the listview, the application crashes!

  • Use of text() function when using xPath in dom4j

    - by jlawless
    I have inherited an application that parses xml using dom4j and xPath: The xml being parsed is similar to the following: <cache> <content> <transaction> <page> <widget name="PAGE_ID">WRK_REGISTRATION</widget> <widget name="TRANS_DETAIL_ID">77145</widget> <widget name="GRD_ERRORS" /> </page> <page> <widget name="PAGE_ID">WRK_REGISTRATION</widget> <widget name="TRANS_DETAIL_ID">77147</widget> <widget name="GRD_ERRORS" /> </page> <page> <widget name="PAGE_ID">WRK_PROCESSING</widget> <widget name="TRANS_DETAIL_ID">77152</widget> <widget name="GRD_ERRORS" /> </page> </transaction> </content> </cache> Individual Nodes are being searched using the following: String xPathToGridErrorNode = "//cache/content/transaction/page/widget[@name='PAGE_ID'][text()='WRK_DNA_REGISTRATION']/../widget[@name='TRANS_DETAIL_ID'][text()='77147']/../widget[@name='GRD_ERRORS_TEMP']"; org.dom4j.Element root = null; SAXReader reader = new SAXReader(); Document document = reader.read(new BufferedInputStream(new ByteArrayInputStream(xmlToParse.getBytes()))); root = document.getRootElement(); Node gridNode = root.selectSingleNode(xPathToGridErrorNode); where xmlToParse is a String of xml similar to the excerpt provided above. The code is trying to obtain the GRD_ERROR node for the page with the PAGE_ID and TRANS_DETAIL_ID provided in the xPath. I am seeing an intermittent (~1-2%) failure (returned node is null) of this selectSingleNode request even though the requested node is in the xml being searched. I know there are some gotchas associated with using text()= in xPath and was wondering if there was a better way to format the xPath string for this type of search.

  • 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); } }

  • Interoperability between two AES algorithms

    - by lpfavreau
    Hello, I'm new to cryptography and I'm building some test applications to try and understand the basics of it. I'm not trying to build the algorithms from scratch but I'm trying to make two different AES-256 implementation talk to each other. I've got a database that was populated with this Javascript implementation stored in Base64. Now, I'm trying to get an Objective-C method to decrypt its content but I'm a little lost as to where the differences in the implementations are. I'm able to encrypt/decrypt in Javascript and I'm able to encrypt/decrypt in Cocoa but cannot make a string encrypted in Javascript decrypted in Cocoa or vice-versa. I'm guessing it's related to the initialization vector, nonce, counter mode of operation or all of these, which quite frankly, doesn't speak to me at the moment. Here's what I'm using in Objective-C, adapted mainly from this and this: @implementation NSString (Crypto) - (NSString *)encryptAES256:(NSString *)key { NSData *input = [self dataUsingEncoding: NSUTF8StringEncoding]; NSData *output = [NSString cryptoAES256:input key:key doEncrypt:TRUE]; return [Base64 encode:output]; } - (NSString *)decryptAES256:(NSString *)key { NSData *input = [Base64 decode:self]; NSData *output = [NSString cryptoAES256:input key:key doEncrypt:FALSE]; return [[[NSString alloc] initWithData:output encoding:NSUTF8StringEncoding] autorelease]; } + (NSData *)cryptoAES256:(NSData *)input key:(NSString *)key doEncrypt:(BOOL)doEncrypt { // 'key' should be 32 bytes for AES256, will be null-padded otherwise char keyPtr[kCCKeySizeAES256 + 1]; // room for terminator (unused) bzero(keyPtr, sizeof(keyPtr)); // fill with zeroes (for padding) // fetch key data [key getCString:keyPtr maxLength:sizeof(keyPtr) encoding:NSUTF8StringEncoding]; NSUInteger dataLength = [input length]; // See the doc: For block ciphers, the output size will always be less than or // equal to the input size plus the size of one block. // That's why we need to add the size of one block here size_t bufferSize = dataLength + kCCBlockSizeAES128; void* buffer = malloc(bufferSize); size_t numBytesCrypted = 0; CCCryptorStatus cryptStatus = CCCrypt(doEncrypt ? kCCEncrypt : kCCDecrypt, kCCAlgorithmAES128, kCCOptionECBMode | kCCOptionPKCS7Padding, keyPtr, kCCKeySizeAES256, nil, // initialization vector (optional) [input bytes], dataLength, // input buffer, bufferSize, // output &numBytesCrypted ); if (cryptStatus == kCCSuccess) { // the returned NSData takes ownership of the buffer and will free it on deallocation return [NSData dataWithBytesNoCopy:buffer length:numBytesCrypted]; } free(buffer); // free the buffer; return nil; } @end Of course, the input is Base64 decoded beforehand. I see that each encryption with the same key and same content in Javascript gives a different encrypted string, which is not the case with the Objective-C implementation that always give the same encrypted string. I've read the answers of this post and it makes me believe I'm right about something along the lines of vector initialization but I'd need your help to pinpoint what's going on exactly. Thank you!

  • WPF Reusing Xaml Effectively

    - by Steve
    Hi, I've recently been working on a project using WPF to produce a diagram. In this I must show text alongside symbols that illustrate information associated with the text. To draw the symbols I initially used some png images I had produced. Within my diagram these images appeared blurry and only looked worse when zoomed in on. To improve on this I decided I would use a vector rather than a rastor image format. Below is the method I used to get the rastor image from a file path: protected Image GetSymbolImage(string symbolPath, int symbolHeight) { Image symbol = new Image(); symbol.Height = symbolHeight; BitmapImage bitmapImage = new BitmapImage(); bitmapImage.BeginInit(); bitmapImage.UriSource = new Uri(symbolPath); bitmapImage.DecodePixelHeight = symbolHeight; bitmapImage.EndInit(); symbol.Source = bitmapImage; return symbol; } Unfortunately this does not recognise vector image formats. So instead I used a method like the following, where "path" is the file path to a vector image of the format .xaml: public static Canvas LoadXamlCanvas(string path) { //if a file exists at the specified path if (File.Exists(path)) { //store the text in the file string text = File.ReadAllText(path); //produce a canvas from the text StringReader stringReader = new StringReader(text); XmlReader xmlReader = XmlReader.Create(stringReader); Canvas c = (Canvas)XamlReader.Load(xmlReader); //return the canvas return c; } return null; } This worked but drastically killed performance when called repeatedly. I found the logic necessary for text to canvas conversion (see above) was the main cause of the performance problem therefore embedding the .xaml images would not alone resolve the performance issue. I tried using this method only on the initial load of my application and storing the resulting canvases in a dictionary that could later be accessed much quicker but I later realised when using the canvases within the dictionary I would have to make copies of them. All the logic I found online associated with making copies used a XamlWriter and XamlReader which would again just introduce a performance problem. The solution I used was to copy the contents of each .xaml image into its own user control and then make use of these user controls where appropriate. This means I now display vector graphics and performance is much better. However this solution to me seems pretty clumsy. I'm new to WPF and wonder if there is some built in way of storing and reusing xaml throughout an application? Apologies for the length of this question. I thought having a record of my attempts might help someone with any similar problem. Thanks.

But when i run the report in SSRS and select more than 3 values for the parameter PI_REGION_LIST the report throws an error on this dataset, ora-00939 error,too many arguments for function. I am not able to figure out the error here. Please help me with an idea. Thanks in advance, Suni.

An example of how this works for say the 'Year of Birth' is: <select name="DOB3"> <option value="">Year</option> <?php for ($i=date('Y'); $i>=1900; $i--) { echo "<option value='$i'"; if ($fields["DOB3"] == $i) echo " selected"; echo ">$i</option>"; } ?> </select> If an error is found, the year of birth value returns the year previously entered. I am able to have this work on all field with the exception of my 'State' field. I build the array and function for the drop down with the following code: <?php $states_arr = array('AL'=>"Alabama",'AK'=>"Alaska",'AZ'=>"Arizona",'AR'=>"Arkansas",'CA'=>"California",'CO'=>"Colorado",'CT'=>"Connecticut",'DE'=>"Delaware",'DC'=>"District Of Columbia",'FL'=>"Florida",'GA'=>"Georgia",'HI'=>"Hawaii",'ID'=>"Idaho",'IL'=>"Illinois", 'IN'=>"Indiana", 'IA'=>"Iowa", 'KS'=>"Kansas",'KY'=>"Kentucky",'LA'=>"Louisiana",'ME'=>"Maine",'MD'=>"Maryland", 'MA'=>"Massachusetts",'MI'=>"Michigan",'MN'=>"Minnesota",'MS'=>"Mississippi",'MO'=>"Missouri",'MT'=>"Montana",'NE'=>"Nebraska",'NV'=>"Nevada",'NH'=>"New Hampshire",'NJ'=>"New Jersey",'NM'=>"New Mexico",'NY'=>"New York",'NC'=>"North Carolina",'ND'=>"North Dakota",'OH'=>"Ohio",'OK'=>"Oklahoma", 'OR'=>"Oregon",'PA'=>"Pennsylvania",'RI'=>"Rhode Island",'SC'=>"South Carolina",'SD'=>"South Dakota",'TN'=>"Tennessee",'TX'=>"Texas",'UT'=>"Utah",'VT'=>"Vermont",'VA'=>"Virginia",'WA'=>"Washington",'WV'=>"West Virginia",'WI'=>"Wisconsin",'WY'=>"Wyoming"); function showOptionsDrop($array, $active, $echo=true){ $string = ''; foreach($array as $k => $v){ $s = ($active == $k)? ' selected="selected"' : ''; $string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n"; } if($echo) { echo $string;} else { return $string;} } ?> I then call the function from within the form using: <td><select name="State"><option value="">Choose a State</option><?php showOptionsDrop($states_arr, null, true); ?></select></td> Not sure what I'm missing but would love any assistance if somebody sees the error in my code. Thanks!

  • How to access a field's value via reflection (Scala 2.8)

    - by soc
    Consider the following code: class Foo(var name: String = "bar") Now i try to get the value and the correct type of it via reflection: val foo = new Foo val field = foo.getDeclaredField("name") field.setAccessible(true) //This is where it doesn't work val value = field.get(????) I tried things like field.get(foo), but that just returns an java.lang.Object but no String. Basically I need the correct type, because I want to invoke a method on it (e. g. toCharArray). What is the suggested way to do that?

  • Match HTML tags in two strings using regex in Python

    - by jack
    I want to verify that the HTML tags present in a source string are also present in a target string. For example: >> source = '<em>Hello</em><label>What's your name</label>' >> verify_target(’<em>Hi</em><label>My name is Jim</label>') True >> verify_target('<label>My name is Jim</label><em>Hi</em>') True >> verify_target('<em>Hi<label>My name is Jim</label></em>') False

  • Understanding WebRequest

    - by Nai
    I found this snippet of code here that allows you to log into a website and get the response from the logged in page. However, I'm having trouble understanding all the part of the code. I've tried my best to fill in whatever I understand so far. Hope you guys can fill in the blanks for me. Thanks string nick = "mrbean"; string password = "12345"; //this is the query data that is getting posted by the website. //the query parameters 'nick' and 'password' must match the //name of the form you're trying to log into. you can find the input names //by using firebug and inspecting the text field string postData = "nick=" + nick + "&password=" + password; // this puts the postData in a byte Array with a specific encoding //Why must the data be in a byte array? byte[] data = Encoding.ASCII.GetBytes(postData); // this basically creates the login page of the site you want to log into WebRequest request = WebRequest.Create("http://www.mrbeanandme.com/login/"); // im guessing these parameters need to be set but i dont why? request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = data.Length; // this opens a stream for writing the post variables. // im not sure what a stream class does. need to do some reading into this. Stream stream = request.GetRequestStream(); // you write the postData to the website and then close the connection? stream.Write(data, 0, data.Length); stream.Close(); // this receives the response after the log in WebResponse response = request.GetResponse(); stream = response.GetResponseStream(); // i guess you need a stream reader to read a stream? StreamReader sr = new StreamReader(stream); // this outputs the code to console and terminates the program Console.WriteLine(sr.ReadToEnd()); Console.ReadLine();

  • Excel data connection - remove header row?

    - by ekoner
    The excel spreadsheet is connecting to SQL server 2005 using the connection string below: Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=True;Initial Catalog=XXXXXX;Data Source=XXXXXX;Extended Properties="HDR=No";Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=XXXXXX;Use Encryption for Data=False;Tag with column collation when possible=False It then pulls data from a view into Excel. The business user wants this information without a header row. This will allow her to review then save as a "headless" csv in SAGE file format. I attempted to alter the connection string by adding HDR=No but that hasn't worked. Additionally, I can't delete the header row. Deleting the content replaces the column names with "Column 1" etc. Any ideas appreciated!

  • [Android] accessing another Activity's preferences

    - by Raffaele
    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

  • sampling integers uniformly efficiently in python using numpy/scipy

    - by user248237
    I have a problem where depending on the result of a random coin flip, I have to sample a random starting position from a string. If the sampling of this random position is uniform over the string, I thought of two approaches to do it: one using multinomial from numpy.random, the other using the simple randint function of Python standard lib. I tested this as follows: from numpy import * from numpy.random import multinomial from random import randint import time def use_multinomial(length, num_points): probs = ones(length)/float(length) for n in range(num_points): result = multinomial(1, probs) def use_rand(length, num_points): for n in range(num_points): rand(1, length) def main(): length = 1700 num_points = 50000 t1 = time.time() use_multinomial(length, num_points) t2 = time.time() print "Multinomial took: %s seconds" %(t2 - t1) t1 = time.time() use_rand(length, num_points) t2 = time.time() print "Rand took: %s seconds" %(t2 - t1) if __name__ == '__main__': main() The output is: Multinomial took: 6.58072400093 seconds Rand took: 2.35189199448 seconds it seems like randint is faster, but it still seems very slow to me. Is there a vectorized way to get this to be much faster, using numpy or scipy? thanks.
