• Calling consecutive java tasks in a shell script

  - by Bigtwinz

  Hi all, This may be a rudimentary question but the answer was not readily available. I'd like to create a shell script that calls 3 tasks consecutively, but wait till the previous task is complete. Like so: a. call first Java program via ant b. call third party Java application c. call third Java program via ant I'm wondering if there is a way to check and ensure a. is done before b. is called and same for b. and c. thanks

• Is it possible to disable the iPhone's automatic hyperlinks?

  - by mririgo

  We send out a notification email whenever we have "phishing" emails reported to us. In these emails, we include a copy-paste of the text inside the original phishing email as a sample of what is reported to us. Our code strips all hyperlinks out of the email via PHP, but still includes (in plain text) the link. When users receive this email in their client (Thunderbird, Outlook, Horde/IMP, etc), the hyperlink is removed. However, the iPhone likes to take web addresses in plain text and automatically turn them into hyperlinks. Is there any possible way to stop this action from happening via a HTML tag or by using PHP to replace certain parts of the hyperlink?

• php $_POST array empty upon form submission...

  - by Mike D

  Hi folks, I'm baffled on this after much googling. This issue is simple, I have a custom CMS i've built that works perfectly on my dev box (Ubuntu/PHP5+/MySQL5+). I just moved it up to the production box for my client and now all form submissions are showing up as empty $_POST arrays. I found a trick to verify the data is actually being passed using "file_get_contents('php://input');" and the data is showing up fine there -- the $_POST/$_REQUEST arrays are always empty. I've also verified the content-type headers are correct as well via firebug (application/x-www-form-urlencoded; charset=utf-8). This issue is happening regardless of whether a form is submitting via AJAX or a regular form submit. Any help is greatly appreciated!

• C++ serial port send command

  - by Ilyssis

  Hi there, I have a hardware here, wich communicates over serial port. I use MS Visual C++ 2010, and I want to send a command: <-S-> I am doing this: SerialPort^ serialPort = gcnew SerialPort(portName , 9600, Parity::None, 8, StopBits::One); serialPort->Open(); serialPort->WriteLine("<-S->"); serialPort->Close(); But the command that goes out is <-S->., and not <-S-> (please notice the point that is attached to the outgoing command). I use Free Serial Port Monitor to watch my ingoing/outcoming data. So how can I get rid of that point in <-S->. ? This is what is going out: 3C 2D 53 2D 3E 0A = <-S-. This is what I want: 3C 2D 53 2D 3E = <-S- Thanks for help.

• Understanding protocols

  - by kronicali

  Hi, guys need some insight here. I know the definition of a protocol, being new to this c++ programming is quite a challenging task.I am creating a Multi-threaded chat using SDL/C++, this is a learning experience for me and now i have encounter a hump in which I need to overcome but understanding it is a little more difficult than I had thought.I need to make a chat protocol of some sort, I think...but am stump. Up until this point i have been sending messages in strings of characters.Now that am improving the application to the point where clients can register and login, I need a better way to communicating with my clients and server. thank you.

• Why exactly is calling the destructor for the second time undefined behavior in C++?

  - by sharptooth

  As mentioned in this answer simply calling the destructor for the second time is already undefined behavior 12.4/14(3.8). For example: class Class { public: ~Class() {} }; // somewhere in code: { Class* object = new Class(); object->~Class(); delete object; // UB because at this point the destructor call is attempted again } In this example the class is designed in such a way that the destructor could be called multiple times - no things like double-deletion can happen. The memory is still allocated at the point where delete is called - the first destructor call doesn't call the ::operator delete() to release memory. For example, in Visual C++ 9 the above code looks working. Even C++ definition of UB doesn't directly prohibit things qualified as UB from working. So for the code above to break some implementation and/or platform specifics are required. Why exactly would the above code break and under what conditions?

• jQuery get request against Sinatra does not get text

  - by jerhinesmith

  I have a very simple sinatra site that I'm trying to access via ajax through jQuery. To keep things incredibly simple, this code snippet: get '/behavior_count' do "60" end which returns "60" in the browser, shows up as an empty string when attempting to access the site via $.get in jQuery. The strange part is in Firebug, while the Response is empty, the HTTP header correctly describes Content-Length as 2, and I can see the request show up on the server. Is there something specific to Sinatra that isn't returning my data, or am I not using jQuery correctly? If it helps, I also tried this code: get '/behavior_count' do content_type 'text/plain', :charset => 'utf-8' "60" end and my jQuery looks like $.get('http://mysite:4567/behavior_count'); // Ignore the response, but // watch the request in firebug Any ideas?

• Exception wrapping and HTML pages

  - by dotnetdev

  Hi, We have a sharepoint 2007 project at work. The exception handling policy is to log to the Sharepoint logs. In this case, would the best approach be to call that method and then rethrow the exception higher up? Except if I rethrow it to be caught higher up, there is no other exception handling code so what would happen in this case? Also, if you are going to display a more friendly error to the user (which uses information in the exception object), then this would be a good use of exception wrapping. Would it be a good idea to make a custom aspx page and add these to customerrors, so that on init (not sure of the exact event), I can display exception info in the passed parameter on the page. However, a static html page can't do this so I don't see the point in wrapping exceptions (unless there is a page or alert which uses the exception object). So if a project uses html pages for errors, is there a point in wrapping exceptions? Thanks

• Illegal Instruction When Programming C++ on Linux

  - by remagen

  Heyo, My program, which does exactly the same thing every time it runs (moves a point sprite into the distance) will randomly fail with the text on the terminal 'Illegal Instruction'. My googling has found people encountering this when writing assembly which makes sense because assembly throws those kinds of errors. But why would g++ be generating an illegal instruction like this? It's not like I'm compiling for Windows then running on Linux (which even then, as long as both are on x86 shouldn't AFAIK cause an Illegal Instruction). I'll post the main file below. I can't reliably reproduce the error. Although, if I make random changes (add a space here, change a constant there) that force a recompile I can get a binary which will fail with Illegal Instruction every time it is run, until I try setting a break point, which makes the illegal instruction 'dissapear'. :( #include <stdio.h> #include <stdlib.h> #include <GL/gl.h> #include <GL/glu.h> #include <SDL/SDL.h> #include "Screen.h" //Simple SDL wrapper #include "Textures.h" //Simple OpenGL texture wrapper #include "PointSprites.h" //Simple point sprites wrapper double counter = 0; /* Here goes our drawing code */ int drawGLScene() { /* These are to calculate our fps */ static GLint T0 = 0; static GLint Frames = 0; /* Move Left 1.5 Units And Into The Screen 6.0 */ glLoadIdentity(); glTranslatef(0.0f, 0.0f, -6); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT | GL_STENCIL_BUFFER_BIT); glEnable(GL_POINT_SPRITE_ARB); glTexEnvi(GL_POINT_SPRITE, GL_COORD_REPLACE, GL_TRUE); glBegin( GL_POINTS ); /* Drawing Using Triangles */ glVertex3d(0.0,0.0, 0); glVertex3d(1.0,0.0, 0); glVertex3d(1.0,1.0, counter); glVertex3d(0.0,1.0, 0); glEnd( ); /* Finished Drawing The Triangle */ /* Move Right 3 Units */ /* Draw it to the screen */ SDL_GL_SwapBuffers( ); /* Gather our frames per second */ Frames++; { GLint t = SDL_GetTicks(); if (t - T0 >= 50) { GLfloat seconds = (t - T0) / 1000.0; GLfloat fps = Frames / seconds; printf("%d frames in %g seconds = %g FPS\n", Frames, seconds, fps); T0 = t; Frames = 0; counter -= .1; } } return 1; } GLuint objectID; int main( int argc, char **argv ) { Screen screen; screen.init(); screen.resize(800,600); LoadBMP("./dist/Debug/GNU-Linux-x86/particle.bmp"); InitPointSprites(); while(true){drawGLScene();} }

• How to email CLLocationCoordinate2D as a link

  - by lucasweb

  I am trying to emulate the Maps 'Share Location' via email functionality. I have the latitude and longitude of my location and am currently using it to display the location on a map via MKMapView. I also have functionality that composes an email from the app and I would like to include the location in it but can not figure out how to construct a link, using the longitude and latitude. I have seen other apps with apps with this functionality so I know it is possible. Any help would be much appreciated. Thanks in advance.

• calling database driver in java app [basically a swing app]

  - by user993250

  I have made a java application that allows a user to choose from certain standards and then allows him to customize those standards according to his needs. Now, the customization [via a swing application] that has been made needs to be persistent. For this we use a database [mysql/access] and hook it to the application so that with each customization made, a table [if non-existent] is created [thus making it runtime and we can not pre-determine the table names or the keys of table etc] and an appropriate entry in the table is made. I have written the driver for this connection. How do I call it in the java application and what approach should I take? I would much appreciate that if somebody can refer me some example that not only shows a sample connection being made via driver but its appropriate calls to the database as well so that i can use it as a guide.

• Navigating by foreign keys in ADO.NET Entity Framework/MySQL

  - by Werg38

  I am using ASP.NET MVC2 on top of a MySQL database in VS2008. I am using the MySQL ADO.NET connector 6.2.3 to provide the connection for the ADO.NET Entity Data Model. This is mostly working ok, however navigating via foreign keys is causing me a real headache! Here is a simplified example.. Car (Table) CarID PK Colour Doors ManufacturerID FK Manufacturer (Table) ManufacturerID PK Name In the edmx file I can see the 1-many relationship shown as a navigation property in the both the Car and Manufacturer tables. I create a Models.CarRepository that allows me to returns a IQueryable. At the View I want to be able to display the Manufacturer.Name for each car. This is not accessible via the object I get returned. What is best way to implement this? Have I encountered a limitation of the Entity Framework/MySQL combination?

• Is there a Silverlight equivalent to "Application.OpenForms"?

  - by lightmeetsdark

  Basically, I'm trying to take information entered by the user on one page and print it out to another page via a "printer friendly" version, or report, of something. I have a MainPage.xaml that is, as the name suggests, my main page, but in a window there is the subpage AdCalculator.xaml where the user enters the information and PrintEstimate.xaml that is navigated to via a button on AdCalculator. I would like to be able to transfer the information entered in the textboxes from AdCalculator and print it out via text blocks in PrintEstimate. So in order to do that I have the following code: Views.AdCalculator AdCalc = new Views.AdCalculator(); string PrintCompanyName = AdCalc.CompanyName; string PrintContactName = AdCalc.txt_CustomerName.Text; string PrintBillingAddress1 = AdCalc.txt_BillingAddress.Text; string PrintBillingAddress2 = AdCalc.txt_BillingAddressLine2.Text; string PrintPhoneNumber = AdCalc.txt_PhoneNumber.Text; string PrintNumOfAds = AdCalc.txt_NumofAds.Text; string PrintRateOfPlay = AdCalc.Cmb_Rate.SelectedValue.ToString(); string PrintNumOfMonths = AdCalc.txt_NumofMonths.Text; string PrintTotalDue = AdCalc.txt_InvoiceSummary_TotalDue.Text; PrintEstimate PrintEstimatePage = new PrintEstimate(); PrintEstimatePage.txt_CompanyName.Text = PrintCompanyName; PrintEstimatePage.txt_CustomerName.Text = PrintContactName; PrintEstimatePage.txt_BillingAddress.Text = PrintBillingAddress1; PrintEstimatePage.txt_BillingAddressLine2.Text = PrintBillingAddress2; PrintEstimatePage.txt_PhoneNumber.Text = PrintPhoneNumber; PrintEstimatePage.txt_InvoiceSummary_NumofAds.Text = PrintNumOfAds; PrintEstimatePage.txt_InvoiceSummary_RateofPlay.Text = PrintRateOfPlay; PrintEstimatePage.txt_InvoiceSummary_NumOfMonths.Text = PrintNumOfMonths; PrintEstimatePage.txt_EstimateTotal.Text = PrintTotalDue; Only problem is, when I instantiate the new AdCalculator page, it clears the values, so nothing is actually retained as far as user-input goes. Following a lead from a colleague, I believe all I need to do is change the line Views.AdCalculator AdCalc = new Views.AdCalculator(); to Views.AdCalculator AdCalc = (AdCalculator)Application.OpenForms["AdCalculator"]; except the "Apllication.OpenForms" doesn't register. I know there are a lot of differences in the way C# code-behind is laid out for silverlight applications, so I didn't know if there was an equivalent that anyone knew about to "Application.OpenForms" that would help solve my issue or if there was any other way to go about getting my task done. Thank you very much!

• DirectX text at (x,y,z)

  - by bobobobo

  In OpenGL, you can actually draw text with an XYZ position, and it will appear at that location, but in a fixed size. If anyone's played MechWarrior 2, they used it there for nav points. The text had a 3d position, but it always appeared a fixed size. The nav point was actually a bit of text at that exact point in space. Other than that the ability to place 3d text was pretty much useless.. you'd always want text to be 2d, righT? I'm finally in a position where I want this feature. I have these points in space that I need to assign text information to, i.e. I need to draw text at a fixed size but with a 3d position. Can this be done from DirectX?

I already found articles about using matrix to transform to a point and rotate then transform back.. What remains is to scale the resultant image to fit an array of original size.. How that can be done? (preferably with 2 equations one for x and one for y ) Thanks in advance

• How to show, not download, images in apache?

  - by jawonlee

  I'm dynamically generating some charts using mod_python, in .png and .pdf formats. When a user points to /some/path/some_imagefile_name.png, I want to show the image within the browser, like in this url. I also want the image to be accessible from an HTML <img src=> tag. So far, whenever I point my browser to a .png address from my server, the .png and .pdf are automatically downloaded instead of being viewed. How should I fix this? I tagged this under Apache, since I figured it would be an Apache config thing. If it's not, please point me towards the right direction.

• Hibernate Persistence problems with Bean Mapping (Dozer)

  - by BuffaloBuffalo

  I am using Hibernate 3, and having a particular issue when persisting a new Entity which has an association with an existing detached entity. Easiest way to explain this is via code samples. I have two entities, FooEntity and BarEntity, of which a BarEntity can be associated with many FooEntity: @Entity public class FooEntity implements Foo{ @Id private Long id; @ManyToOne(targetEntity = BarEntity.class) @JoinColumn(name = "bar_id", referencedColumnName = "id") @Cascade(value={CascadeType.ALL}) private Bar bar; } @Entity public class BarEntity implements Bar{ @Id private Long id; @OneToMany(mappedBy = "bar", targetEntity = FooEntity.class) private Set<Foo> foos; } Foo and Bar are interfaces that loosely define getters for the various fields. There are corresponding FooImpl and BarImpl classes that are essentially just the entity objects without the annotations. What I am trying to do is construct a new instance of FooImpl, and persist it after setting a number of fields. The new Foo instance will have its 'bar' member set to an existing Bar (runtime being a BarEntity) from the database (retrieved via session.get(..)). After the FooImpl has all of its properties set, Apache Dozer is used to map between the 'domain' object FooImpl and the Entity FooEntity. What Dozer is doing in the background is instantiating a new FooEntity and setting all of the matching fields. BarEntity is cloned as well via instantiation and set the FooEntity's 'bar' member. After this occurs, passing the new FooEntity object to persist. This throws the exception: org.hibernate.PersistentObjectException: detached entity passed to persist: com.company.entity.BarEntity Below is in code the steps that are occurring FooImpl foo = new FooImpl(); //returns at runtime a persistent BarEntity through session.get() Bar bar = BarService.getBar(1L); foo.setBar(bar); ... //This constructs a new instance of FooEntity, with a member 'bar' which itself is a new instance that is detached) FooEntity entityToPersist = dozerMapper.map(foo, FooEntity.class); ... session.persist(entityToPersist); I have been able to resolve this issue by either removing or changing the @Cascade annotation, but that limits future use for say adding a new Foo with a new Bar attached to it already. Is there some solution here I am missing? I would be surprised if this issue hasn't been solved somewhere before, either by altering how Dozer Maps the children of Foo or how Hibernate reacts to a detached Child Entity.

• ideas for simple objects for day to day web-dev use?

  - by Joel

  Dang-I know this is a subjective question so will probably get booted off/locked, but I'll try anyway, because I don't know where else to ask (feel free to point me to a better place to ask this!) I'm just wrapping my head around oop with PHP, but I'm still not using frameworks or anything. I'd like to create several small simple objects that I could use in my own websites to better get a feel for them. Can anyone recommend a list or a resource that could point me to say 10 day-to-day objects that people would use in basic websites? The reason I'm asking is because I'm confusing myself a bit. For example, I was thinking of a "database connection" object, but then I'm just thinking that is just a function, and not really an "object"?? So the question is: What are some examples of objects used in basic PHP websites (not including "shopping cart" type websites) Thanks!
