Play2.1 Json.validate compiler error "type mismatch; found : *** required: play.api.libs.json.Reads[?]"
jsonR.validate(Inspection) should be just jsonR.validate() , as you have defined the implicit Reads object that will be used for parsing.

Error with Maven/Scala: error: not found: type classOf
You're trying to input a class object (the object that represents a class) as a type identifier (the identifier of a class, consisting of its name and generic constraints in case of generic classes) . Just use VolatilityImpl directly, i.e. : class ScalaHibernateVolatilityDaoImpl(persistentClass : VolatilityImpl) This is unrelated to Maven, by the way.

Django-CMS Type Error "a float is required"
As I wondered, the problem was that I was accessing the site using my temporary link from BlueHost, which the function throwing the error could not handle. When my clients finally pointed their domain name at the server this problem and a few others (CSS inconsistencies in the Django admin, trouble with .htaccess) disappeared. Everything is up now and working fine.

maven error message "1 required artifact is missing"
It seems like you have one maven-Projekt " iseek-content-fetcher-fb" that you are working on and which your reference via dependency in another local project. Maven do not scan your projects in eclipse target folder. It is only aware of maven-artifacts in your local-repository "~/.m2" or remote-repository like http://mvnrepository.com/. You have to compile and install your maven project to local repository with: mvn install install - install the package into the local repository, for use as a dependency in other projects locally

Typescript Error Message error TS2173: Generic type references must include all type arguments
That line should have been: promise(type?: any, target?: any): JQueryPromise<any>; I'll send them a pull request. Thanks. JQueryPromise is a generic interface. i.e. it takes type parameters. Starting with TS 0.9.1.1 they are more strict about generic parameters. They must be specified from now on. This was allowed in previous versions (where the type was assumed to any implicitly) but the compiler analysis is stricter now (and the type must be specified explicitly).

While using Table Type data type in PL/SQL getting 'NO DATA FOUND' error
In your code i is an index. It steps through the bounds monotonically. So if your minimum EMPNO is 1234 and your maximum EMPNO is 5678 the values of i will be 1234, 1235, 1236 ... 5676, 5677, 5678. But that probably is what you want to do, because EMPNO is likely to be a sparse array, with missing numbers. So if you have no row in EMP where EMPNO=1235 your query will throw NO_DATA_FOUND. What's the solution? Use a bulk collect instead: select * bulk collect into v_emp from emp ; That will select all the rows in the table, and it will be more efficient as well.

Scala Type Mismatch underlying type and class vs method
The problem in your code is type parameter shadowing. You have: class ThreeStacks[A, B, C](val stackSize:Int = 1000) { def push1[A](value: A): Unit = stack1.push(value) ... } It should be: class ThreeStacks[A, B, C](val stackSize:Int = 1000) { def push1(value: A): Unit = stack1.push(value) ... } The way you have done it, type parameter A of class ThreeStacks and type parameter A of method push1 are completely different ones and thus, are incompatible with each other. The same applies to B and C.

Does a variable of an interface type act as value type if the underlying implementation is a struct?
No, interface is a contract, to make it work properly you need to use ref keyword. public void SetInterfaceProp(ref IMyInterface thingy) { thingy.desc = "the implementing type is a struct"; } What matters here is a real type that stays inside that interface wrap. To be more clear: even if code with method SetInterfaceProp defined like public void SetInterfaceProp(IMyInterface thingy) { thingy.desc = "the implementing type is a struct"; } will work: IMyInterface inter= default(MyStruct); SetInterfaceProp(inter); this one will not : MyStruct inter = default(MyStruct); SetInterfaceProp(inter); You can not gurantee that the caller of your method will always use IMyInterface, so to guarantee expected behavior, in this case, you can define ref keyword, that will guaran

Reread your own code: @interface SecondViewController : UIViewController @property(strong,nonatomic)SecondViewController *secondViewController; @end What you want in your FirstViewController.h file is this: #import <UIKit/UIKit.h> #import "SecondViewController.h" @interface FirstViewController : UIViewController @property (strong, nonatomic) IBOutlet UIImageView *bGround; @property(strong,nonatomic)SecondViewController *secondViewController; - (IBAction)settingsPressed:(id)sender; - (IBAction)startPressed:(id)sender

How to convert nullable type to its underlying type?
But it supports nullable types, AllowDbNull is true by default: var table = new DataTable(); table.Columns.Add("NullableInt", typeof(int)); table.Rows.Add(1); table.Rows.Add(2); table.Rows.Add(3); table.Rows.Add((int?)null); Use the DataRow extension methods which support nullable types, for example: foreach(DataRow row in table.Rows) { int? value = row.Field<Int32?>("NullableInt"); // modify the value with SetField: row.SetField<Int32?>("NullableInt", null); // or: row.SetField("NullableInt", (int?)null); }

Property 'frame' not found on object of type 'UISearchBar' error
UISearchBar is a class. It doesn't have a class method setFrame. It does have an instance method though and that's what you should be using. So, you need an instance of UISearchBar, either that you already have or you need to create one. If this is being done when the search bar is selected, your code would be in the delegate method searchBarTextDidBeginEditing: and you would use the supplied parameter: [searchBar setFrame:CGRectMake(newX, newY, searchBar.frame.size.width, yourSearchBar.frame.size.height)];

Property not found on object of type error with method declaration in Objective C
Maybe because you're using the dot notation in a case where it doesn't make much sense : in useFlattenHTML method, self.flattenHTML is the same as [self flattenHTML], which doesn't exist, as you only have [self flattenHTML:someString]. On top of that, dot notation is possible, but you should keep it for fields declared as @property only

Struts2 & Spring error: No qualifying bean of type found for dependency
I've found two solutions for this problem. Since I am using Java configuration for Spring, I had to ensure that my contextConfigLocation was set properly. I am using a jar file that contains beans with Spring stereotypes, so I had to ensure that the jar file was being properly built in eclipse. When building the jar file, I had to ensure that the Add Directory entries options was checked. These two steps solved this problem. I hope this helps!

Why am i getting this error? binary '==' : no operator found which takes a left-hand operand of type 'std::string'
The problem is that you're comparing the string object to a character in your computeValue function. There no overload of operator == in the std namespace which takes both a std::string and a char, hence the error. You should be using char instead of a std::string if you only need a character as input. char getOperation() { std::cout << "Please enter the operator. + - * /" << std::endl; char userOperator; std::cin >> userOperator; return userOperator; } Your parameter should also take a char: float computeValue(float value1, float value2, char operation) // ^^^^

I found this error (Sending 'const uint8_t (*)[kStreamChunkSize]' to parameter of type 'void *' discards qualifiers)?
It discards the const qualifier and that's a problem. getBytes: gets the bytes by writing them into the array passed in. However, you can't write in an array of const bytes (doing so invokes undefined behavior), that's what const means. Change the declaration of your array to uint8_t bytes[kStreamChunkSize]; Furthermore, don't pass a pointer to the array - if you simply use its name without the & operator, it will decay into a pointer to its first element anyway.

scala type error for class with map member typed with existential type
Unless you explicitly require getting the keys back out as the statically correct subtype (which seems unlikely), then the following will work: case class DictVariant1(data: Map[MyBaseType, Double]) val d = List((Concrete1() : MyBaseType, 3.5)).toMap val dv1 = DictVariant1(d) Using a type ascription forces Concrete1() to be seen as an instance of the base type; you'd get the same effect if you added an explicit type to d: val d : Map[MyBaseType, Double] = .... Or if you put multiple entries in such that the type inferencer picks the base type: val d = List((Concrete1(), 3.5), (Concrete2(), 4.5)).toMap The 'get' you use is always going to fail, however, because you're trying to use the whole Map as an index: it works fine if you provide a sensible key: dv1.data.get(Concrete1())

F# error FS0193 (VS 2010) : The type 'WebRequest' is not compatible with the type 'HttpWebRequest'
The error was quite small. The :> operator will only perform casts which are known to succeed at compile time and so won't cast from HttpWebRequest.Create(url) to HttpWebRequest as this actually returns a WebRequest. As a reult you need to use let req = HttpWebRequest.Create(url) :?> HttpWebRequest instead to allow for casting in the other direction in the inheritance tree. The difference is that casts made by :?> may fail at run time (but shouldn't in this case as all urls should be http)

Synat error - The type of the expression must be an array type but it resolved to String
Well yes - data is a String, and you can't use an indexing expression like data[i] on a string. Perhaps you want: if (b.toString().equals(data.substring(i, i + 1)) Although it's far from clear that that's a good idea. Byte.toString probably doesn't do what you expect it to. Perhaps you actually want: if ((char) b == data.charAt(i)) ?

Unity 3 and Error "The type name or alias "xxxxx" could not be resolved. Please check your configuration file and verify this type name."
The problem is in you config file. You are mixing two concepts with some incorrect syntax. The <assembly... /> and <namespace ... /> nodes provide an assembly and namespace search order when your <register ... /> node contains a type that cannot be found by itself. If a type cannot be found, it searches through all combinations of [namespace].Type, [assembly]. Here's where the error is: it does NOT search for Type, [assembly]. If any <namespace ... /> nodes are defined, it does NOT try appending only the assembly. So your <register type="Biblioteca.Contracts.IManterCategoriaBO" mapTo="Biblioteca.Business.ManterCategoriaBO" /> node has the type Biblioteca.Contracts.IManterCategoriaBO which does not contain the assembly, so it cannot be found. Therefore,

If the class is contained in a separate asssembly, make sure your winforms project has a reference to the other assembly. Hope that helps.

Linkage error:Loader Constraint violation: previously initiated loading for a different type with name "org/w3c/dom/Type Info"
This happened to me with the JMX MBeanServer class. Groovy was loading one of them with its classloader and so was the JVM. In your case it sounds like the TypeInfo class exists in rt.jar just fine, but another class loader loads it from that jar (or another jar) again. Running the JRE with "-verbose:class" showed that double load behavior. Then I moved the offending jar out of my classpath and it worked just fine with the one loaded by Groovy. I would recommend moving rt.jar out of your classpath, or if you need other classes inside of rt.jar try unjaring and rejaring it without the Type class. That way the classloaders will be forced to use the ones in xmlbeans-2.5.0.jar or xbean-2.1.0.jar.

error: a value of type "void *" cannot be assigned to an entity of type "float *"
What is happening here is that most likely you are inadvertently compiling your code as C++ code. In C++ (as opposed to C) void * is not implicitly convertible to other pointer types. It you intend to write your code in C, make sure you compile it as C. It you intend to write your code in C++, you will have to use explicit type conversion operators to convert void * pointers to other pointer types. The conversion to long * pointer type probably happens in other translation unit (i.e. other file), which is compiled as C. That is probably why it succeeds. Note that compilers can use C and C++ mode independently for each translation unit. Many compilers will choose between C and C++ based on file extension, compiling .c files as C and .cpp files as C++.
