  • Swift CMutablePointers in factories e.g. NewMusicSequence

    - by Gene De Lisa
    How do you use C level factory methods in Swift? Let's try using a factory such as NewMusicSequence(). OSStatus status var sequence:MusicSequence status=NewMusicSequence(&sequence) This errors out with "error: variable 'sequence' passed by reference before being initialized". Set sequence to nil, and you get EXC_BAD_INSTRUCTION. You can try being explicit like this: var sp:CMutablePointer<MusicSequence>=nil status=NewMusicSequence(sp) But then you get a bad access exception when you set sp to nil. If you don't set sp, you get an "error: variable 'sp' used before being initialized" Here's the reference.

  • How to load program reading stdin and taking parameters in gdb?

    - by vinc456
    I have a program that takes input from stdin and also takes some parameters from command line. It looks like this: cat input.txt myprogram -path "/home/user/work" I try to debug the code with gdb inside emacs, by M-x gdb, I try to load the program with the command: gdb cat input.txt myprogram -path "/home/user/work" However, gdb does not like it. Question cribbed from here. Unfortunately I don't understand the solution and am not sure what to do beyond compiling with the -g option and running the command M-x gdb.

  • COM interop, Office 2010 x64 and Visual Studio 2010.

    - by Snake
    Hi, I just installed Offic 2010 x64 on my Windows 7 x64 laptop. It already had Visual Studio 2010 on it. Now I try to add Microsoft.Office.Interop.Excel or something to the project, but it just can't find the project. When I try to open a project from the website of Microsoft (a sample of Office development) Visual Studio says that that kind of project is not supported. How is this possible? Is it a problem that I installed x64 of Office? Or is the problem Visual Studio 2010? Thanks

  • .NET AxWebBrowser can't open page "Navigation to the webpage was canceled" error

    - by Erdnod
    Oh, I am stuck again on this quiet annoying problem. I am trying to do a little automated browsing using the axWebBrowser component and it worked before. Now all of a sudden I get the following message when I try to browse to a page. Navigation to the webpage was canceled What you can try: Refresh the page. I totally disabled my firewall, ran VS2008 in Administrator mode, I even installed IE8 all to no avail. By the way IE8 doesn't work either. I don't know if the problem is related but all I get when I put a URL into IE8 is this message. Internet Explorer cannot display the webpage I don't so much mind that, I just really need to get my visual studio axWebBrowser working.

  • Does this feature exist? Defining my own curly brackets in C#

    - by Carlos
    You'll appreciate the following two syntactic sugars: lock(obj) { //Code } same as: Monitor.Enter(obj) try { //Code } finally { Monitor.Exit(obj) } and using(var adapt = new adapter()){ //Code2 } same as: var adapt= new adapter() try{ //Code2 } finally{ adapt.Dispose() } Clearly the first example in each case is more readable. Is there a way to define this kind of thing myself, either in the C# language, or in the IDE? The reason I ask is that there are many similar usages (of the long kind) that would benefit from this, eg. if you're using ReaderWriterLockSlim, you want something pretty similar.

How and where from I can get smtp server and kindly also guide how I can do its setting to use on local machine. Thnaks Here is my Code public string SendEmail(Email email) { string errmsg = null; if (dt != null) { try { dt = systemrep.GetSystemInfo(); dr = dt.Rows[0]; From = dr["nm_EmailFrom"].ToString(); SMTP = dr["nm_SMTP"].ToString(); Port = dr["amt_Port"].ToString(); EmailId = dr["nm_emailUserId"].ToString(); EmailPassword = dr["nm_emailPassword"].ToString(); DefaultCredations = Convert.ToBoolean(dr["ind_Credentials"].ToString()); MailMessage message = new MailMessage(); SmtpClient smtp = new SmtpClient(); NetworkCredential mailAuthentication = new NetworkCredential(EmailId, EmailPassword); message.To.Add(new MailAddress(email.To)); message.From = new MailAddress(From); message.IsBodyHtml = true; message.Subject = email.Subject; message.Body = email.Message; smtp.UseDefaultCredentials = DefaultCredations; smtp.EnableSsl = true; smtp.Port = 25; smtp.DeliveryMethod = SmtpDeliveryMethod.Network; smtp.Host = SMTP; smtp.Credentials = new NetworkCredential(EmailId, EmailPassword); smtp.Send(message); } catch (SmtpException smtpEx) { errmsg = string.Format("alert('There was a problem in sending the email: {0}');", smtpEx.Message.Replace("'", "\\'")); } catch (Exception generalEx) { errmsg = string.Format("alert('There was a general problem: {0}');", generalEx.Message.Replace("'", "\\'")); } } else errmsg = "An error accured whilte getting email settings from database, process couldn't be completed"; return errmsg; } }

  • Input not cleared.

    - by SoulBeaver
    As the question says, for some reason my program is not flushing the input or using my variables in ways that I cannot identify at the moment. This is for a homework project that I've gone beyond what I had to do for it, now I just want the program to actually work :P Details to make the finding easier: The program executes flawlessly on the first run through. All throws work, only the proper values( n 0 ) are accepted and turned into binary. As soon as I enter my terminate input, the program goes into a loop and only asks for the termiante again like so: When I run this program on Netbeans on my Linux Laptop, the program crashes after I input the terminate value. On Visual C++ on Windows it goes into the loop like just described. In the code I have tried to clear every stream and initialze every variable new as the program restarts, but to no avail. I just can't see my mistake. I believe the error to lie in either the main function: int main( void ) { vector<int> store; int terminate = 1; do { int num = 0; string input = ""; if( cin.fail() ) { cin.clear(); cin.ignore( numeric_limits<streamsize>::max(), '\n' ); } cout << "Please enter a natural number." << endl; readLine( input, num ); cout << "\nThank you. Number is being processed..." << endl; workNum( num, store ); line; cout << "Go again? 0 to terminate." << endl; cin >> terminate // No checking yet, just want it to work! cin.clear(); }while( terminate ); cin.get(); return 0; } or in the function that reads the number: void readLine( string &input, int &num ) { int buf = 1; stringstream ss; vec_sz size; if( ss.fail() ) { ss.clear(); ss.ignore( numeric_limits<streamsize>::max(), '\n' ); } if( getline( cin, input ) ) { size = input.size(); for( int loop = 0; loop < size; ++loop ) if( isalpha( input[loop] ) ) throw domain_error( "Invalid Input." ); ss << input; ss >> buf; if( buf <= 0 ) throw domain_error( "Invalid Input." ); num = buf; ss.clear(); } }

  • Problem Loading AS2 swf into AS3 swf

    - by dani
    I've been trying very hard to get an AS2 swf to load properly inside an AS3 swf - but to no avail ... The AS2 file (which is a rather big app referencing many external xml files etc.) works perfectly when launched in Flash Player. When trying to load the same file through an AS3 swf (using URLRequest and Loader classes), the file starts loading but stops abruptly during the preloading phase. (Same happens if I try to load it using AS2 "loadMovie".) What is there more to try? Security settings, custom loader classes - any advice is appreciated.

  • Obj-C Error: Expected expression before ...... (why?)

    - by Horatiu Paraschiv
    Hi I have an enum declared like this: typedef enum { Top, Bottom, Center } UIItemAlignment; In my code I try to use it like this: item.alignment = UIItemAlignment.Top; I get an error like this: " Expected expression before 'UIItemAlignment' " If I use only: item.alignment = Top; everything works fine but why do I get this error if I try to use it the other way? _alignment is an NSInteger and it has a property declared like this @property (readwrite) NSInteger alignment; and I synthesized it in my implementation file. So my question is, why do I get this error?

  • php pdo connection scope

    - by Scarface
    Hey guys I have a connection class I found for pdo. I am calling the connection method on the page that the file is included on. The problem is that within functions the $conn variable is not defined even though I stated the method was public (bare with me I am very new to OOP), and I was wondering if anyone had an elegant solution other then using global in every function. Any suggestions are greatly appreciated. CONNECTION class PDOConnectionFactory{ // receives the connection public $con = null; // swich database? public $dbType = "mysql"; // connection parameters // when it will not be necessary leaves blank only with the double quotations marks "" public $host = "localhost"; public $user = "user"; public $senha = "password"; public $db = "database"; // arrow the persistence of the connection public $persistent = false; // new PDOConnectionFactory( true ) <--- persistent connection // new PDOConnectionFactory() <--- no persistent connection public function PDOConnectionFactory( $persistent=false ){ // it verifies the persistence of the connection if( $persistent != false){ $this->persistent = true; } } public function getConnection(){ try{ // it carries through the connection $this->con = new PDO($this->dbType.":host=".$this->host.";dbname=".$this->db, $this->user, $this->senha, array( PDO::ATTR_PERSISTENT => $this->persistent ) ); // carried through successfully, it returns connected return $this->con; // in case that an error occurs, it returns the error; }catch ( PDOException $ex ){ echo "We are currently experiencing technical difficulties. We have a bunch of monkies working really hard to fix the problem. Check back soon: ".$ex->getMessage(); } } // close connection public function Close(){ if( $this->con != null ) $this->con = null; } } PAGE USED ON include("includes/connection.php"); $db = new PDOConnectionFactory(); $conn = $db->getConnection(); function test(){ try{ $sql = 'SELECT * FROM topic'; $stmt = $conn->prepare($sql); $result=$stmt->execute(); } catch(PDOException $e){ echo $e->getMessage(); } } test();

  • Errors caught by WBT, but not BBT and vice versa

    - by David Relihan
    Hi Folks, Can you think of one type of error that might be found using White-Box testing, and one type using Black-Box testing. i.e. an error that would be found by one and not the other. For WBT there would null else statements, but what would you catch with BBT and not WBT??? BTW this question is just based on my own personal study - I'm not getting free marks out of this!!!! Thanks,

  • Namespaces and deserialization issue

    - by CaffGeek
    UPDATE: You can run the code at the end of this to recreate and see the error I am having and hopefully solve it! UPDATE2: It's not the removal of the xmlns="" that's the issue... as you can remove it from the initial xml string. The problem is with the [XmlType(TypeName = "Systems")] somehow causing it to be added... UPDATE3: Turns out the problem is in here, I need to set the TypeName based on what is in the existing, XmlTypeAttribute if it already exists on the class.... xmlAttributes.XmlType = new XmlTypeAttribute { Namespace = "" }; I get the following XML as a string from a webservice <Systems xmlns=""> <System id="1"> <sys_name>ALL</sys_name> </System> <System id="2"> <sys_name>asdfasdf</sys_name> </System> <System id="3"> <sys_name>fasdfasf</sys_name> </System> <System id="4"> <sys_name>asdfasdfasdf</sys_name> </System> </Systems> I then execute this, to convert it to an object result = XElement.Parse(xmlResult.OuterXml).Deserialize<AwayRequestSystems>(); Strangely though, in the Deserialize method, while the RemoveAllNamespaces works and returns the xml without the namespace I get the error <Systems xmlns=''> was not expected. in the catch when return (T) serializer.Deserialize(reader); executes!

  • How to completely wipe rubygems along with rails etc

    - by Earlz
    Ok, so I decided I'd be cool and try to use Rails3 that's in beta. Then, things were getting hard to manage so I got rvm. I installed ruby 1.9.2-head in rvm and things were working, and then a computer restart later rails wouldn't start up. So I figured I'd just try running the system ruby and start rails in it. same error. Then, I uninstalled rails3 and got rails: no such file or directory type errors.. So now I'm royally screwed because rails2 is still installed but will not uninstall because of invisible dependencies, along with a lot of other random gems. How do I completely clear out all ruby gems and such so I can start anew?

  • SSRS 2008 Interactive Sorting in Sub-Report not working as expected

    - by Ray J
    I have a (parent) report that has a list. The details group of this list contains one sub-report. So basically if the list has 10 records (rows) the sub-report is executed 10 times. The problem seems to be with interactive sorting in the Sub-Report. It has 4 columns with interactive sorting enabled. When I run the parent report and try to sort columns SSRS "remembers" the previous sort column and sorts by multiple columns at the same time. For example if I sort by Col A then click to sort by Col B, SSRS will preserve the sorting of Col A (and the direction) and then apply the sorting to Col B. However I simply want to sort by Col B and do not want to Col A to be part of the sort. When I try this directly with the sub-report everything works as expected. Any ideas why this is happening?

  • Multiple login locations for an online app.

    - by Goro
    Hello, I am working on a browser based application that will have many users. The catch is that every user should have their own customized login page, but the actual application is the same for everyone, and needs to be in a central location. What is the most secure way of doing this? Would it make more sense to have a copy of the application for each user, and keep the database centralized? The projected number of users is not very high, probably around 20-80. Thank you,

  • how to: handle exceptions, best practices

    - by b0x0rz
    need to implement a global error handling, so maybe you can help out with the following example... i have this code: public bool IsUserAuthorizedToSignIn(string userEMailAddress, string userPassword) { // get MD5 hash for use in the LINQ query string passwordSaltedHash = this.PasswordSaltedHash(userEMailAddress, userPassword); // check for email / password / validity using (UserManagementDataContext context = new UserManagementDataContext()) { var users = from u in context.Users where u.UserEMailAdresses.Any(e => e.EMailAddress == userEMailAddress) && u.UserPasswords.Any(p => p.PasswordSaltedHash == passwordSaltedHash) && u.IsActive == true select u; // true if user found return (users.Count() == 1) ? true : false; } } and the md5 as well: private string PasswordSaltedHash(string userEMailAddress, string userPassword) { MD5 hasher = MD5.Create(); byte[] data = hasher.ComputeHash(Encoding.Default.GetBytes(userPassword + userEMailAddress)); StringBuilder stringBuilder = new StringBuilder(); for (int i = 0; i < data.Length; i++) { stringBuilder.Append(data[i].ToString("x2")); } Trace.WriteLine(String.Empty); Trace.WriteLine("hash: " + stringBuilder.ToString()); return stringBuilder.ToString(); } so, how would i go about handling exceptions from these functions? they first one is called from the Default.aspx page. the second one is only called from other functions from the class library. what is the best practice? surround code INSIDE each function with try-catch surround the FUNCTION CALL with try-catch something else?? what to do if exceptions happen? in this example: this is a user sign in, so somehow even if everything fails, the user should get some meaningful info - along the lines: sign in ok (just redirect), sign in not ok (wrong user name / password), sign in not possible due to internal problems, sorry (exception happened). for the first function i am worried if there is a problem with database access. not sure if there is anything that needs to be handled in the second one. thnx for the info. how would you do it? need specific info on this (easier for me to understand), but also general info on how to handle other tasks/functions. i looked around the internet but everyone has different things to say, so unsure what to do... will go with either most votes here, or most logicaly explained answer :) thank you.

  • ASP.NET Exception Handling in background threads

    When I do ThreadPool.QueueUserWorkItem, I don't want unhandled exceptions to kill my entire process. So I do something like: ThreadPool.QueueUserWorkItem(delegate() { try { FunctionIActuallyWantToCall(); } catch { HandleException(); } }); Is this the recommended pattern? It seems like there should be a simpler way to do this. It's in an asp.net-mvc app, if that's relevant.
