  • Python: writing a program to compute the area of a circle and square

    - by user1672504
    I have a question with an assignment. I'm not sure how to write this program and I really need help! Could someone help me with this? This is the assignment: Write a program that asks the user to enter two values: an integer choice and a real number x. If choice is 1, compute and display the area of a circle of radius x. If choice is 2, compute and display the are of a square with sides of length x. If choice is neither 1, nor 2, will display the text Invalid choice. Sample run: Enter choice: 2 Enter x: 8 The area is: 64.0 Sample run: Enter choice: 1 Enter x: 8 The area is: 201.06176 My attempt: choice = input ('Enter Choice:') choice_1 = int (choice) if (choice_1==1): radius = (int) print('Enter x:',radius) pi = 3.14159 area = ( radius ** 2 ) * pi print ( 'The Area is=' , area )

  • Query to return internal details about stored function in SQL Server database

    - by Anthony
    I have been given access to a SQL Server database that is currently used by 3rd party app. As such, I don't have any documentation on how that application stores the data or how it retrieves it. I can figure a few things out based on the names of various tables and the parameters that the user-defined functions takes and returns, but I'm still getting errors at every other turn. I was thinking that it would be really helpful if I could see what the stored functions were doing with the parameters given to return the output. Right now all I've been able to figure out is how to query for the input parameters and the output columns. Is there any built-in information_schema table that will expose what the function is doing between input and output?

  • Not able to override CSS within IFrame

    - by Madhur Ahuja
    I am using disqus comments for my jekyll blog with some CSS styles overriden in my stylesheet and used to work perfectly. Recently, disqus has introduced a new UI for their comments system which has completely broken the font colors. Since my site has dark background, I am trying to apply styles based on new disqus HTML structure generated. However, it seems that none of my styles get applied. It seems that is because disqus is loaded within iframe. Any ideas how can I fix the font colors. Example of the post: http://www.madhur.co.in/blog/2012/03/27/codeplexmovegit.html UPDATE Based on this question How to apply CSS to iFrame? it seems that you cannot style a child IFrame cross domain. I am wondering how it used to work earlier. Disqus even has documentation on it http://docs.disqus.com/help/69/

  • Open source ASP.net webforms examples

    - by Yaaqov
    I learning ASP.net, and am looking to create a rather straightforward WebForms ASP.net application, but I have very limited examples to work with. Is there a site that has a lot of ASP.net WebForms projects that are downloadable? Books seem to focus on narrow aspects of using Webforms, like session control, or using master pages, but I'm looking for examples of how a whole app comes together. Or, better yet, is there someone willing to help a new developer out one-on-one by sharing a project or two of his? I'd appreciate any help. Thanks.

  • WCF Advanced Books

    - by hgulyan
    Hi, I've read all questions like mine and found a few good links. My question is about architect of WCF, how it is designed, how is generated reference.vb, wsdl and xsd files. How can I do that manually, some good examples of WCF Systems (mostly on desktop applications over TCP). I'd like a book or documentation or anything else, that can give me advanced knowledge of WCF. What do you think of this book http://www.amazon.com/Professional-WCF-Windows-Communication-Foundation/dp/0470563141/ref=sr_1_5?ie=UTF8&s=books&qid=1269425390&sr=8-5 ? And generally is there any source that would give me this all or the only way is practising, trying, looking in all that generated files and reading documentations? Thank you.

  • Connect two UIScrollView's together

    - by johnw188
    Here's a tricky iPhone problem I've been working on. I have three UIScrollViews on a page, one that only scrolls horizontally, one that only scrolls vertically, and one that scrolls both horizontally and vertically. I want to lock the views together, so that the horizontal location of the horizontal only scrollview matches the horizontal location of the main scrollview, and the vertical scrollview likewise, so that dragging the main scrollview around controls the horizontal and vertical scrollviews. Problem is, I'm completely stumped. I've looked around inside the apple documentation, but there doesn't seem to be any way to do this officially. One thought that I had was to somehow "clone" any touch on any of the scrollviews to a point on the other two, but I have no idea how to do this. If anyone has any thoughts on this, I'd very much appreciate it.

  • TestCase scripting framework

    - by Mikey
    Hey guys, For our webapp testing environment we're currently using watin with a bunch of unit tests, and we're looking to move to selenium and use more frameworks. We're currently looking at Selenium2 + Gallio + Xunit.net, However one of the things we're really looking to get around is compiled testcases. Ideally we want testcases that can be edited in VS with intellisense, but don't require re-compilling the assembly every single time we make a small change, Are there any frameworks likely to help with this issue? Are there any nice UI tools to help manage massive ammount of testcases? Ideally we want the testcase writing process to be simple so that more testers can aid in writing them. cheers

  • Display all images from outside web root folder using PHP

    - by micmola
    Hello, I want to display all images that are stored outside my web root folder. Please help me. I am only able to display one image repeatedly. For example, if I have 5 images in my folder, only one image is displayed on my browser 5 times. Please help me on this. I've been working on this problem for over a month now. I'm a newbie. Help.

  • macdeployqt and third party libraries

    - by user338170
    I've got an application project that depends on a couple of shared libraries that I have created myself. According to the Qt 4.6 documentation "Deploying an Application on Mac OSX": Note: If you want a 3rd party library to be included in your application bundle, then you must add an excplicit lib entry for that library to your application's .pro file. Otherwise, the macdeployqt tool will not copy the 3rd party .dylib into the bundle. I have added lib entries to my application's .pro file but the libraries that I have written do not get copied into the bundle when I execute macdeployqt. I have the following in my .pro file: LIBS += -L../Libraries -lMyLib Everything builds okay, its just when I try to run from the bundle that I run into problems i.e. "image not found" errors. Is there a bug in macdeployqt or do I have to something more to my .pro file?

  • How do I get the current color of a fragment?

    - by Mason Wheeler
    I'm trying to wrap my head around shaders in GLSL, and I've found some useful resources and tutorials, but I keep running into a wall for something that ought to be fundamental and trivial: how does my fragment shader retrieve the color of the current fragment? You set the final color by saying gl_FragColor = whatever, but apparently that's an output-only value. How do you get the original color of the input so you can perform calculations on it? That's got to be in a variable somewhere, but if anyone out there knows its name, they don't seem to have recorded it in any tutorial or documentation that I've run across so far, and it's driving me up the wall.

  • Loading an OverlayView from XIB -vs- programmatically for use with UIImagePickerController

    - by PLG
    I am currently making a camera app for iPhone and I have a strange phenomenon that I can't figure out. I would appreciate some help understanding. When recreating an overlay view for passing to UIImagePickerController, I have been successfully been able to create the view programmatically. What I haven't been able to do is create the view with/without controller in IB, load it and pass it to the overlay pointer successfully. If I do it via IB, the view is not opaque and obscures the view of the camera completely. I can not figure out why. I was thinking that the normal view pointer might be assigned when loading from XIB and therefore overwrite the camera's view, but I have an example programmatically where view and overlayView are set equal in the controller class. Perhaps the load order is overwriting a pointer? Help would be appreciated... kind regards.

  • Freebase Query with "JOINS"

    - by codemonkey
    ... Yeah, yeah, I know traditional joins don't exist. I actually like the freebase query methodology in theory, just having a little trouble getting it to actually work for me : ) Anyone have a dumb-simple example of getting Freebase data via MQL that pulls from two different "tables"? In particular, I'm trying to get automotive data... so for example, pulling fields from both /automotive/model_year and /automotive/trim_year. I've read the documentation (for hours actually). There's a distinct possibility that I'm looking right at such an example somewhere and just not seeing it because my OLTP brain just doesn't comprehend what it's seeing. * Note * ... that the two "types" I'm working with above are siblings, not parent/child. Does freebase even allow joining data between sibling nodes... I see examples of queries pulling from parent/child, but not from siblings I don't think (or I've overlooked them).

  • What design pattern do you use the most?

    - by spoon16
    I'm interested in understanding what design patterns people find themselves using often. Hopefully this list will help other recognize common scenarios and the associated design pattern that can be used to solve them. Please describe a common problem you find yourself solving and the design pattern(s) you use to solve it. Links to blogs or documentation describing the pattern are also appreciated. Edit: Please expand on your answers a bit, I would like this to be a useful reference for someone who wants to learn more about design patterns and is curious on what situations a specific design pattern might be used. Nobody has linked to any "more learning" resources.

  • Problem with connection to MS SQL Server database using SSMS

    - by Charles
    I have a database on line with Godaddy (who uses SQL Server 2005). They provide basic management tools, but tell you that for more advanced tools you can connect directly using SSMS. I followed their instructions to ensure my online database will accept remote connections, and can apparently log in using SSMS with success (after giving my hostname and access data). However: When attempting to expand the "Databases" folder tree, I get the following error: Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server& LinkId=20476 ADDITIONAL INFORMATION: An exception occurred while executing a Transact-SQL statement or batch.

  • Would this hack for per-object permissions in django work?

    - by Edward
    According to the documentation, a class can have the meta option permissions, described as such: Options.permissions Extra permissions to enter into the permissions table when creating this object. Add, delete and change permissions are automatically created for each object that has admin set. This example specifies an extra permission, can_deliver_pizzas: permissions = (("can_deliver_pizzas", "Can deliver pizzas"),) This is a list or tuple of 2-tuples in the format (permission_code, human_readable_permission_name). Would it be possible to define permissions at run time by: permissions = (("can_access_%s" % self.pk, / "Has access to object %s of type %s" % (self.pk,self.__name__)),) ?

  • Books or Articles on Using NUnit to Test Entire Features

    - by INTPnerd
    Are there any books or articles that show you how to use NUnit to test entire features of a program? Is there a name for this type of testing? This is different from the typical use of NUnit for unit testing where you test individual classes. This is similar to acceptance testing except that it is written by the developer to discern that the program does what they interpreted as being what the customer wants the program to do. I don't need it to be readable by non-programmers or to produce a readable specification for non-programmers. The problem I am having is keeping this feature testing code maintainable. I need help in organizing my feature testing code. I also need help organizing the program code to be drivable in this way. I am having a hard time being able to issue commands to the program while still having good code design.

  • Incongruity between Eclipse Outline/Package perspective and source code being displayed - Java error generated at runtime

    - by David Daedalus
    I've been debugging a Java application and have encountered something odd. When a particular method is called, Java throws a ClassNotFoundException. Unfortunately, the methods in question (the invoking and the 'missing' one) are inside a JAR file for which I have no documentation or source. To get at the source, I used JD-GUI (a Java JAR reverse engineer-er) and the JD plugin for Eclipse. As far as I can tell, the class in question exists inside the JAR file. This because JD-GUI displays it inside the JAR, and from within Eclipse I can see it listed along with the constructors and methods. My question is why the source being displayed in Eclipse is for a different class (that also exists)? This program was built with Ant - is it possible the problem lies there? Screenshot below for your viewing pleasure - and thanks in advance for your help!

  • How are binding specified for Interface Builder plugins?

    - by Benedict Cohen
    I'm creating an Interface Builder plugin for an NSView subclass. I've been following the Interface Builder Plug-in Programming Guide but it's not answer all my questions. My class has one NSString property and 4 NSColor properties which I want to create bindings for at design time. I can't figure out where the bindings are specified in the plugin project. The documentation states that the Inspector Object is only for creating the Attribute Inspector. The class description file (.classdescription) lists outlets and actions but not bindings. Where do I specify the bindings for my class?

  • Paypal - DoExpressCheckoutPayment null pointer

    - by user969894
    String nvpstr = "&TOKEN=" + token + "&PAYERID=" + payerID + "&PAYMENTREQUEST_0_PAYMENTACTION=" + paymentType + "&PAYMENTREQUEST_0_AMT=" + finalPaymentAmount + "&PAYMENTREQUEST_0_CURRENCYCODE=" + currencyCodeType + "&IPADDRESS=" + serverName; Having done an earlier call to SetExpressCheckout, I had to change a few parameter names because Paypal had changed it in the documentation but not in the code from the integration wizard. Now for DoExpressCheckoutPayment I've modified a few but I get a null pointer at strAck: HashMap nvp = httpcall("DoExpressCheckoutPayment", nvpstr); String strAck = nvp.get("ACK").toString(); if (strAck.equalsIgnoreCase("Success")) { return nvp; } Not sure what is wrong, any suggestions for debugging this or possible solutions?

  • Paypal recuring IPN signals

    - by user1548981
    When creating Paypal recurring payments i don't receive any notifications from IPN that the recurring payments were actually made. I do receive the notifications that recurring profiles are created, that regular payments are made, that profile is canceled and so on. But no notifications when Paypal make the recurring payment. The file that process the ipn notification works fine and i think is bug free.It also send me an email every time he got something from Paypal(with row POST data) so i don't think the problem is here. Does Paypal send these notifications.If i set a daily recurring payment i should get a daily notification that payment was made? From what i read in documentation i should get these signals but.. Thanks
