  • Python - Why use anything other than uuid4() for unique strings?

    - by orokusaki
    I see quit a few implementations of unique string generation for things like uploaded image names, session IDs, et al, and many of them employ the usage of hashes like SHA1, or others. I'm not questioning the legitimacy of using custom methods like this, but rather just the reason. If I want a unique string, I just say this: >>> import uuid >>> uuid.uuid4() 07033084-5cfd-4812-90a4-e4d24ffb6e3d And I'm done with it. I wasn't very trusting before I read up on uuid, so I did this: >>> import uuid >>> s = set() >>> for i in range(5000000): # That's 5 million! >>> s.add(uuid.uuid4()) ... ... >>> len(s) 5000000 Not one repeater (I didn't expect one considering the odds are like 1.108e+50, but it's comforting to see it in action). You could even half the odds by just making your string by combining 2 uuid4()s. So, with that said, why do people spend time on random() and other stuff for unique strings, etc? Is there an important security issue or other regarding uuid?

  • How to debug/break in codedom compiled code

    - by Jason Coyne
    I have an application which loads up c# source files dynamically and runs them as plugins. When I am running the main application in debug mode, is it possible to debug into the dynamic assembly? Obviously setting breakpoints is problematic, since the source is not part of the original project, but should I be able to step into, or break on exceptions for the code? Is there a way to get codedom to generate PDBs for this or something? Here is the code I am using for dynamic compliation. CSharpCodeProvider codeProvider = new CSharpCodeProvider(new Dictionary<string, string>() { { "CompilerVersion", "v3.5" } }); //codeProvider. ICodeCompiler icc = codeProvider.CreateCompiler(); CompilerParameters parameters = new CompilerParameters(); parameters.GenerateExecutable = false; parameters.GenerateInMemory = true; parameters.CompilerOptions = string.Format("/lib:\"{0}\"", Application.StartupPath); parameters.ReferencedAssemblies.Add("System.dll"); parameters.ReferencedAssemblies.Add("System.Core.dll"); CompilerResults results = icc.CompileAssemblyFromSource(parameters, Source); DLL.CreateInstance(t.FullName, false, BindingFlags.Default, null, new object[] { engine }, null, null);

  • error C2512 in precompiled header file?

    - by SoloMael
    I'm having a ridiculously strange problem. When I try to run the program below, there's an error message that says: "error C2512: 'Record' : no appropriate default constructor available". And when I double-click it, it directs me to a precompiled read-only header file named "xmemory0". Do they expect me to change a read-only file? Here's the segment of code in the file it directs me to: void construct(_Ty *_Ptr) { // default construct object at _Ptr ::new ((void *)_Ptr) _Ty(); // directs me to this line } Here's the program: #include <iostream> #include <vector> #include <string> using namespace std; const int NG = 4; // number of scores struct Record { string name; // student name int scores[NG]; double average; // Calculate the average // when the scores are known Record(int s[], double a) { double sum = 0; for(int count = 0; count != NG; count++) { scores[count] = s[count]; sum += scores[count]; } average = a; average = sum / NG; } }; int main() { // Names of the class string names[] = {"Amy Adams", "Bob Barr", "Carla Carr", "Dan Dobbs", "Elena Evans"}; // exam scores according to each student int exams[][NG]= { {98, 87, 93, 88}, {78, 86, 82, 91}, {66, 71, 85, 94}, {72, 63, 77, 69}, {91, 83, 76, 60}}; vector<Record> records(5); return 0; }

    i have a client thats sending a message to the ejbserver using UDP, i want the server(stateless bean) to echo back this message to the client but i cant seem to do this. or can i implement the same logic by using JMS? please help and enlighten. this is just a test, in the end i want a midp to be sending the message to the ejb using datagrams. here is my code. @Stateless public class SessionFacadeBean implements SessionFacadeRemote { public SessionFacadeBean() { } public static void main(String[] args) { DatagramSocket aSocket = null; byte[] buffer = null; try { while(true) { DatagramPacket request = new DatagramPacket(buffer, buffer.length); aSocket.receive(request); DatagramPacket reply = new DatagramPacket(request.getData(), request.getLength(), request.getAddress(), request.getPort()); aSocket.send(reply); } } catch (SocketException e) { System.out.println("Socket: " + e.getMessage()); } catch (IOException e) { System.out.println("IO: " + e.getMessage()); } finally { if(aSocket != null) aSocket.close(); } } } and the client: public static void main(String[] args) { DatagramSocket aSocket = null; try { aSocket = new DatagramSocket(); byte [] m = "Test message!".getBytes(); InetAddress aHost = InetAddress.getByName("localhost"); int serverPort = 6789; DatagramPacket request = new DatagramPacket(m, m.length, aHost, serverPort); aSocket.send(request); byte[] buffer = new byte[1000]; DatagramPacket reply = new DatagramPacket(buffer, buffer.length); aSocket.receive(reply); System.out.println("Reply: " + new String(reply.getData())); } catch (SocketException e) { System.out.println("Socket: " + e.getMessage()); } catch (IOException e) { System.out.println("IO: " + e.getMessage()); } finally { if(aSocket != null) aSocket.close(); } } please help.

  • Can can I reference extended methods/params without having to cast from the base class object return

    - by Greg
    Hi, Is there away to not have a "cast" the top.First().Value() return to "Node", but rather have it automatically assume this (as opposed to NodeBase), so I then see extended attributes for the class I define in Node? That is is there a way to say: top.Nodes.First().Value.Path; as opposed to now having to go: ((Node)top.Nodes.First().Value).Path) thanks [TestMethod()] public void CreateNoteTest() { var top = new Topology(); Node node = top.CreateNode("a"); node.Path = "testpath"; Assert.AreEqual("testpath", ((Node)top.Nodes.First().Value).Path); // *** HERE *** } class Topology : TopologyBase<string, Node, Relationship> { } class Node : NodeBase<string> { public string Path { get; set; } } public class NodeBase<T> { public T Key { get; set; } public NodeBase() { } public NodeBase(T key) { Key = key; } } public class TopologyBase<TKey, TNode, TRelationship> where TNode : NodeBase<TKey>, new() where TRelationship : RelationshipBase<TKey>, new() { // Properties public Dictionary<TKey, NodeBase<TKey>> Nodes { get; private set; } public List<RelationshipBase<TKey>> Relationships { get; private set; } }

  • function in php for displaying a menu

    - by Stanislas Piotrowski
    I met some trouble with a function I have written. In fact I have an array in which I have different custom values. I would like to display the result of that, so here is my function function getAccess($var){ $data=mysql_fetch_array(mysql_query("SELECT * FROM `acces` WHERE `id`='.$var.'")); return $data; } getAccess($_SESSION['id']); $paramAcces = array( 'comptesfinanciers' => array( 'libelle' => 'COMPTES FINANCIERS', 'acces' => $data['comptesfinanciers'], 'lien' => 'financier', 'image' => 'images/finances.png' ) ); I have done a var_dump of $paramAcces which return array(1) { ["comptesfinanciers"]=> array(4) { ["libelle"]=> string(18) "COMPTES FINANCIERS" ["acces"]=> NULL ["lien"]=> string(9) "financier" ["image"]=> string(19) "images/finances.png" } } (that are the ecpected values). Here is the function for displaying what is in the array /** * AFFICHAGE DE LA SECTION PARAMETRES SUR LA PAGE D'ACCUEIL */ function affichParam($paramAccees){ echo '<ul class="getcash-vmenu"><li><a href="index.php?p='.$paramAccees['lien'].'" class="active"><span class="t"><img src="'.$paramAccees['image'].'"> '.$paramAccees['libelle'].'</span></a></li></ul>'; } The trouble is that actualy it return to me an empty line. I really do not know what I'm wrong doin: I call the function like that: <?php affichParam($paramAccees) ?> In a second time I will add more value, so I think I will have to do a for each loop or something like that. But actualy I just would like to display the first record. Any kind of help will be much apprecitaed

  • Overloading operator>> to a char buffer in C++ - can I tell the stream length?

    - by exscape
    I'm on a custom C++ crash course. I've known the basics for many years, but I'm currently trying to refresh my memory and learn more. To that end, as my second task (after writing a stack class based on linked lists), I'm writing my own string class. It's gone pretty smoothly until now; I want to overload operator that I can do stuff like cin my_string;. The problem is that I don't know how to read the istream properly (or perhaps the problem is that I don't know streams...). I tried a while (!stream.eof()) loop that .read()s 128 bytes at a time, but as one might expect, it stops only on EOF. I want it to read to a newline, like you get with cin to a std::string. My string class has an alloc(size_t new_size) function that (re)allocates memory, and an append(const char *) function that does that part, but I obviously need to know the amount of memory to allocate before I can write to the buffer. Any advice on how to implement this? I tried getting the istream length with seekg() and tellg(), to no avail (it returns -1), and as I said looping until EOF (doesn't stop reading at a newline) reading one chunk at a time.

  • @WebServices as @Stateless session bean in ejb jar

    - by kislo_metal
    Hi! Scenario: Creating some web service as @Stateless bean, package it as ejb jar. Result - can`t access to wsdl file. Goal: I want to use @WebServices as @Stateless session using ejb jar packaging with accessible wsdl file form web. Web service: @Stateless @WebService(serviceName = "ws.isp.SecurityService", wsdlLocation = "META-INF/wsdl/SecurityService.wsdl") public class SecurityService{ @EJB private Kerberos factory; @EJB private UsersServiceBean uService; public SecurityService() { } @WebMethod @WebResult(name = "SimpleResponse") public SimpleResponse LogOut( @WebParam(name = "sessionUUID", targetNamespace = "https://secure.co.ua/ws/") String sessionUUID ) { SimpleResponse resp = new SimpleResponse(); try{ factory.removeSession(sessionUUID); resp.setError(WSErrorCodes.SUCCESS); }catch (Exception e){ e.printStackTrace(); resp.setError(WSErrorCodes.UNRELOSVED_ERROR); } return resp; } @WebMethod public MySession logIn( @WebParam(name = "username", targetNamespace = "https://secure.co.ua/ws/") String username, @WebParam(name = "password", targetNamespace = "https://secure.co.ua/ws/") String password){ MySession result = new MySession(); try { UserSession us = factory.creatSession(uService.getUser(username, password).getId()); result.setSessionID(us.getSessionUUID().toString()); result.setError(WSErrorCodes.SUCCESS); } catch (NullPointerException e){ e.printStackTrace(); result.setError(WSErrorCodes.UNRELOSVED_USER); } catch (Exception e){ e.printStackTrace(); result.setError(WSErrorCodes.UNRELOSVED_ERROR); } return result; } } In this case I getting Invalid wsdl request http://192.168.44.48:8181/ws.isp.SecurityService/SecurityService when I try to access to wsdl and if do not use description of wsdlLocation I getting blank page. Web service as it self working good. Q1: what is the rule of describing wsdl file location for web services as stateless in ejb jar. Q2: is it possible to generate wsdl file during maven packaging ? Q3: how to generate wsdl file for web service where we have such annotation as @Stateless and @EJB (currently I can generate it only by commenting those annotations) environment: mave 2, ejb 3.1, glassfish v3, jax-ws 2.x Thank you!

  • [iphone,twitter] Accessing the Twitter API through a proxy using NSURLConnectionsm, OAuth problem

    - by akaii
    I'm having no problems with sending an update directly via hxxps://api.twitter.com/, but the app (for the Iphone, I'm using NSURLConnections) I'm working is supposed to allow the user to select a preferred proxy (e.g. hxxps://twitter-proxy.appspot.com/api/ or hxxps://nest.onedd.net/api/), and I keep getting a 401 error (Failed to validate oauth signature and token) whenever I try to get an access token via these proxies. Even though I send my POST request to the proxy, I am still using the direct url for the api (https:// api.twitter.com/[rest api path]) in the base string. Despite the 401 error message above, the status code I'm actually getting from connection:didReceiveResponse: is 200, probably because it was able to successfully contact the proxy... Is there anything else that I need to consider when using a proxy to access the API? Should anything in the authorization header change, for example? Or the base string? I can manage to connect via Basic Auth without issue, but support for that will be dropped in a month. On a somewhat unrelated note... What are the possible causes of Twitter's error 403, and how do you distinguish between them? Is the only way to differentiate an error due to exceeding the status update limit for an hour (150 per hour) vs for a day (1000 per day) by checking the string reply returned in the response? Is there any way for me to simulate a status update limit error without going through the motions of actually sending 150/1000 tweets?

  • Is there a more efficient way to run enum values through a switch-case statement in C# than this?

    - by C Patton
    I was wondering if there was a more efficient (efficient as in simpler/cleaner code) way of making a case statement like the one below... I have a dictionary. Its key type is an Enum and its value type is a bool. If the boolean is true, I want to change the color of a label on a form. The variable names were changed for the example. Dictionary<String, CustomType> testDict = new Dictionary<String, CustomType>(); //populate testDict here... Dictionary<MyEnum, bool> enumInfo = testDict[someString].GetEnumInfo(); //GetEnumInfo is a function that iterates through a Dictionary<String, CustomType> //and returns a Dictionary<MyEnum, bool> foreach (KeyValuePair<MyEnum, bool> kvp in enumInfo) { switch (kvp.Key) { case MyEnum.Enum1: if (someDictionary[kvp.Key] == true) { Label1.ForeColor = Color.LimeGreen; } else { Label1.ForeColor = Color.Red; } break; case MyEnum.Enum2: if (someDictionary[kvp.Key] == true) { Label2.ForeColor = Color.LimeGreen; } else { Label2.ForeColor = Color.Red; } break; } } So far, MyEnum has 8 different values.. which means I have 8 different case statements.. I know there must be an easier way to do this, I just can't conceptualize it in my head. If anyone could help, I'd greatly appreciate it. I love C# and I learn new things every day.. I absorb it like a sponge :) -CP

  • initialising a 2-dim Array in Scala

    - by Stefan W.
    (Scala 2.7.7:) I don't get used to 2d-Arrays. Arrays are mutable, but how do I specify a 2d-Array which is - let's say of size 3x4. The dimension (2D) is fixed, but the size per dimension shall be initializable. I tried this: class Field (val rows: Int, val cols: Int, sc: java.util.Scanner) { var field = new Array [Char](rows)(cols) for (r <- (1 to rows)) { val line = sc.nextLine () val spl = line.split (" ") field (r) = spl.map (_.charAt (0)) } def put (val rows: Int, val cols: Int, c: Char) = todo () } I get this error: :11: error: value update is not a member of Char field (r) = spl.map (_.charAt (0)) If it would be Java, it would be much more code, but I would know how to do it, so I show what I mean: public class Field { private char[][] field; public Field (int rows, int cols, java.util.Scanner sc) { field = new char [rows][cols]; for (int r = 0; r < rows; ++r) { String line = sc.nextLine (); String[] spl = line.split (" "); for (int c = 0; c < cols; ++c) field [r][c] = spl[c].charAt (0); } } public static void main (String args[]) { new Field (3, 4, new java.util.Scanner ("fraese.fld")); } } and fraese.fld would look, for example, like that: M M M M . M I get some steps wide with val field = new Array Array [Char] but how would I then implement 'put'? Or is there a better way to implement the 2D-Array. Yes, I could use a one-dim-Array, and work with put (y, x, c) = field (y * width + x) = c but I would prefer a notation which looks more 2d-ish.

  • What is the Difference between GC.GetTotalMemory(false) and GC.GetTotalMemory(true)

    - by somaraj
    Hi, Could some one tell me the difference between GC.GetTotalMemory(false) and GC.GetTotalMemory(true); I have a small program and when i compared the results the first loop gives an put put < loop count 0 Diff = 32 for GC.GetTotalMemory(true); and < loop count 0 Diff = 0 for GC.GetTotalMemory(false); but shouldnt it be the otherway ? Smilarly rest of the loops prints some numbers ,which are different for both case. what does this number indicate .why is it changing as the loop increase. struct Address { public string Streat; } class Details { public string Name ; public Address address = new Address(); } class emp :IDisposable { public Details objb = new Details(); bool disposed = false; #region IDisposable Members public void Dispose() { Disposing(true); } void Disposing(bool disposing) { if (!disposed) disposed = disposing; objb = null; GC.SuppressFinalize(this); } #endregion } class Program { static void Main(string[] args) { long size1 = GC.GetTotalMemory(false); emp empobj = null; for (int i = 0; i < 200;i++ ) { // using (empobj = new emp()) //------- (1) { empobj = new emp(); //------- (2) empobj.objb.Name = "ssssssssssssssssss"; empobj.objb.address.Streat = "asdfasdfasdfasdf"; } long size2 = GC.GetTotalMemory(false); Console.WriteLine( "loop count " +i + " Diff = " +(size2-size1)); } } } }

  • Is this trivial function silly?

    - by Chas. Owens
    I came across a function today that made me stop and think. I can't think of a good reason to do it: sub replace_string { my $string = shift; my $regex = shift; my $replace = shift; $string =~ s/$regex/$replace/gi; return $string; } The only possible value I can see to this is that it gives you the ability to control the default options used with a substitution, but I don't consider that useful. My first reaction upon seeing this function get called is "what does this do?". Once I learn what it does, I am going to assume it does that from that point on. Which means if it changes, it will break any of my code that needs it to do that. This means the function will likely never change, or changing it will break lots of code. Right now I want to track down the original programmer and beat some sense into him or her. Is this a valid desire, or am I missing some value this function brings to the table?

  • std::list iterator: get next element

    - by sheepsimulator
    I'm trying to build a string using data elements stored in a std::list, where I want commas placed only between the elements (ie, if elements are {A,B,C,D} in list, result string should be "A,B,C,D". This code does not work: typedef std::list< shared_ptr<EventDataItem> > DataItemList; // ... std::string Compose(DataItemList& dilList) { std::stringstream ssDataSegment; for(iterItems = dilList.begin(); iterItems != dilList.end(); iterItems++) { // Lookahead in list to see if next element is end if((iterItems + 1) == dilList.end()) { ssDataSegment << (*iterItems)->ToString(); } else { ssDataSegment << (*iterItems)->ToString() << ","; } } return ssDataSegment.str(); } How do I get at "the-next-item" in a std::list using an iterator? I would expect that it's a linked-list, why can't I get at the next item?

  • How to deal with "partial" dates (2010-00-00) from MySQL in Django?

    - by Etienne
    In one of my Django projects that use MySQL as the database, I need to have a date fields that accept also "partial" dates like only year (YYYY) and year and month (YYYY-MM) plus normal date (YYYY-MM-DD). The date field in MySQL can deal with that by accepting 00 for the month and the day. So 2010-00-00 is valid in MySQL and it represent 2010. Same thing for 2010-05-00 that represent May 2010. So I started to create a PartialDateField to support this feature. But I hit a wall because, by default, and Django use the default, MySQLdb, the python driver to MySQL, return a datetime.date object for a date field AND datetime.date() support only real date. So it's possible to modify the converter for the date field used by MySQLdb and return only a string in this format 'YYYY-MM-DD'. Unfortunately the converter use by MySQLdb is set at the connection level so it's use for all MySQL date fields. But Django DateField rely on the fact that the database return a datetime.date object, so if I change the converter to return a string, Django is not happy at all. Someone have an idea or advice to solve this problem? How to create a PartialDateField in Django ? EDIT Also I should add that I already thought of 2 solutions, create 3 integer fields for year, month and day (as mention by Alison R.) or use a varchar field to keep date as string in this format YYYY-MM-DD. But in both solutions, if I'm not wrong, I will loose the special properties of a date field like doing query of this kind on them: Get all entries after this date. I can probably re-implement this functionality on the client side but that will not be a valid solution in my case because the database can be query from other systems (mysql client, MS Access, etc.)

  • Hibernate: Check if object exists/changed

    - by swalkner
    Assuming I have an object Person with long id String firstName String lastName String address Then I'm generating a Person-object somewhere in my application. Now I'd like to check if the person exists in the database (= firstname/lastname-combination is in the database). If not = insert it. If yes, check, if the address is the same. If not = update the address. Of course, I can do some requests (first, try to load object with firstname/lastname), then (if existing), compare the address. But isn't there a simpler, cleaner approach? If got several different classes and do not like to have so many queries. I'd like to use annotations as if to say: firstname/lastname = they're the primary key. Check for them if the object exists. address is the parameter you have to compare if it stayed the same or not. Does Hibernate/JPA (or another framework) support something like that? pseude-code: if (database.containsObject(person)) { //containing according to compound keys if (database.containsChangedObject(person)) { database.updateObject(person); } } else { database.insertObject(person); }

  • [Android]problem when delete contacts,please help me

    - by Enchor
    I have been working with Android contacts. I am able to show them, update but when I want to delete any, it is not deleted completely. In Contacts application is shown as (Unknown) without any data. Here is my example: ArrayList ops = new ArrayList(); ops.add(ContentProviderOperation.newDelete(Data.CONTENT_URI) .withSelection(Data.CONTACT_ID + "=?", new String[]{selectedid}) .build()); getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops); Should I do anything else to delete contact entirely? It seems that these code delete info in table ContactsContract.Data but it does not delete element related in table ContactsContract.Contacts or ContactsContract.RawContacts.how can i do to delete an contact completely? ============================================================================ also, i tried deprecated method. It dose work, but i do not want to do so. Here is the sample code: ContentResolver contentResolver = m_cContent.getContentResolver(); contentResolver.delete(People.CONTENT_URI, People.NAME + "=?", new String[] { SelectedName }); and if i modify this code to ContentResolver contentResolver = m_cContent.getContentResolver(); contentResolver.delete(ContactsContract.Contacts, ContactsContract.Contacts._ID + "=?", new String[] { Selectedid }); It has no effect. Does it mean that one can only delete a contact by name instead of by its id? What on earth can i do to delete contact? Thanks, Enchor

  • Windows-1251 file inside UTF-8 site?

    - by Spoonk
    Hello everyone Masters Of Web Delevopment :) I have a piece of PHP script that fetches last 10 played songs from my winamp. This script is inside file (lets call it "lastplayed.php") which is included in my site with php include function inside a "div". My site is on UTF-8 encoding. The problem is that some songs titles are in Windows-1251 encoding. And in my site they displays like "??????"... Is there any known way to tell to this div with included "lastplayed.php" in it, to be with windows-1251 encoding? Or any other suggestions? P.S: The file with fetching script a.k.a.

  • Which view will be resolved, code from spring's docs

    - by Blankman
    So when you go to /appointments the get() action is called, so then would the view be get.jsp (assuming you are using .jsp, and assuming you are mapping action names to views)? And what about the getnewform? It seems to be returning an object? Is that basically passed into the view? @Controller @RequestMapping("/appointments") public class AppointmentsController { private final AppointmentBook appointmentBook; @Autowired public AppointmentsController(AppointmentBook appointmentBook) { this.appointmentBook = appointmentBook; } @RequestMapping(method = RequestMethod.GET) public Map<String, Appointment> get() { return appointmentBook.getAppointmentsForToday(); } @RequestMapping(value="/{day}", method = RequestMethod.GET) public Map<String, Appointment> getForDay(@PathVariable @DateTimeFormat(iso=ISO.DATE) Date day, Model model) { return appointmentBook.getAppointmentsForDay(day); } @RequestMapping(value="/new", method = RequestMethod.GET) public AppointmentForm getNewForm() { return new AppointmentForm(); } @RequestMapping(method = RequestMethod.POST) public String add(@Valid AppointmentForm appointment, BindingResult result) { if (result.hasErrors()) { return "appointments/new"; } appointmentBook.addAppointment(appointment); return "redirect:/appointments"; } } In the example, the @RequestMapping is used in a number of places. The first usage is on the type (class) level, which indicates that all handling methods on this controller are relative to the /appointments path. The get() method has a further @RequestMapping refinement: it only accepts GET requests, meaning that an HTTP GET for /appointments invokes this method. The post() has a similar refinement, and the getNewForm() combines the definition of HTTP method and path into one, so that GET requests for appointments/new are handled by that method.

  • How can I execute a .sql from C#?

    - by J. Pablo Fernández
    For some integration tests I want to connect to the database and run a .sql file that has the schema needed for the tests to actually run, including GO statements. How can I execute the .sql file? (or is this totally the wrong way to go?) I've found a post in the MSDN forum showing this code: using System.Data.SqlClient; using System.IO; using Microsoft.SqlServer.Management.Common; using Microsoft.SqlServer.Management.Smo; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { string sqlConnectionString = "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True"; FileInfo file = new FileInfo("C:\\myscript.sql"); string script = file.OpenText().ReadToEnd(); SqlConnection conn = new SqlConnection(sqlConnectionString); Server server = new Server(new ServerConnection(conn)); server.ConnectionContext.ExecuteNonQuery(script); } } } but on the last line I'm getting this error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. --- System.TypeInitializationException: The type initializer for '' threw an exception. --- .ModuleLoadException: The C++ module failed to load during appdomain initialization. --- System.DllNotFoundException: Unable to load DLL 'MSVCR80.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E). I was told to go and download that DLL from somewhere, but that sounds very hacky. Is there a cleaner way to? Is there another way to do it? What am I doing wrong? I'm doing this with Visual Studio 2008, SQL Server 2008, .Net 3.5SP1 and C# 3.0.

  • Logging class using delegates (NullReferenceException)

    - by Leroy Jenkins
    I have created a small application but I would now like to incorporate some type of logging that can be viewed via listbox. The source of the data can be sent from any number of places. I have created a new logging class that will pass in a delegate. I think Im close to a solution but Im receiving a NullReferenceException and I don’t know the proper solution. Here is an example of what Im trying to do: Class1 where the inbound streaming data is received. class myClass { OtherClass otherClass = new OtherClass(); otherClass.SendSomeText(myString); } Logging Class class OtherClass { public delegate void TextToBox(string s); TextToBox textToBox; Public OtherClass() { } public OtherClass(TextToBox ttb) { textToBox = ttb; } public void SendSomeText(string foo) { textToBox(foo); } } The Form public partial class MainForm : Form { OtherClass otherClass; public MainForm() { InitializeComponent(); otherClass = new OtherClass(this.TextToBox); } public void TextToBox(string pString) { listBox1.Items.Add(pString); } } Whenever I receive data in myClass, its throwing an error. Any help you could give would be appreciated.

  • Mixing c++ standard strings and windows API

    - by JB
    Many windows APIs take a pointer to a buffer and a size element but the result needs to go into a c++ string. (I'm using windows unicode here so they are wstrings) Here is an example :- #include <iostream> #include <string> #include <vector> #include <windows.h> using namespace std; // This is the method I'm interested in improving ... wstring getComputerName() { vector<wchar_t> buffer; buffer.resize(MAX_COMPUTERNAME_LENGTH+1); DWORD size = MAX_COMPUTERNAME_LENGTH; GetComputerNameW(&buffer[0], &size); return wstring(&buffer[0], size); } int main() { wcout << getComputerName() << "\n"; } My question really is, is this the best way to write the getComputerName function so that it fits into C++ better, or is there a better way? I don't see any way to use a string directly without going via a vector unless I missed something? It works fine, but somehow seems a little ugly. The question isn't about that particular API, it's just a convenient example.
