Spring Batch: unit test late binding
testing,spring-batch,late-binding
You are setting the from and to as step execution context variables in your test. But in your application context configuration you are retrieving them as job parameters.

Detect and use optional external C library at runtime in Objective-C
ios,objective-c,c,static-libraries,late-binding
Use dlsym to get the C function pointers by function name. If it can find them, they're there. Otherwise they're not. Just use RTLD_DEFAULT as the first parameter. EDIT: having cast around for an iOS example, see Mike Ash's write up of PLWeakCompatibility, particularly the section on 'Falling Through'. You'll...
how to populate an instance created by Activator.CreateInstance() method [duplicate]
Check out this question: how to create an instance of class and set properties from a Bag object like session Type myType = Type.GetType(className); var instance = System.Activator.CreateInstance(myType); PropertyInfo[] properties = myType.GetProperties(); foreach (var property in properties) { property.SetValue(instance, session[property.Name], null); } ...
How allow for '.' in an Excel file name when 'saving as' using late binding?
c#,excel,reflection,late-binding
Why do you remove .xls from your filepath with filepath.Remove(filepath.LastIndexOf(".")) I just tested this myself, if I use just filepath as in workbook.GetType().InvokeMember("SaveAs", BindingFlags.InvokeMethod, null, workbook, new Object[] { filepath, 56 }); it works for me...

Achieve generic method invocation depending on the type given
c#,entity-framework,generics,late-binding
will this lead to an invocation of the BuildQuery method according to the generic type or will it invoke the non-generic method? It will use the non-generic overload. And in the second case, is there a way to achieve that kind of method invocation? You can type the variable...
VBA - Using Typeof … Is ADODB.Recordset Results in Compile Error
ms-access,access-vba,ado,late-binding,adox
Just to recap, without an ADO reference included in your project, you get a compile error at this line: If TypeOf adoRsColumns Is ADODB.Recordset Then Without the reference, VBA doesn't recognize ADODB.Recordset The situation is basically the same as if you tried to declare Dim rs As ADODB.Recordset without the...
Call function of template class created at runtime
c++,class,templates,c++11,late-binding
The simplest way to do this is: class IClass{ virtual ~IClass {} virtual void foobar()=0; }; template<typename T> class MyClass:public IClass { public: void foobar() override { // code here } }; std::unique_ptr<IClass> myclassptr {}; if(use_int) { myclassptr.reset(new MyClass<int>()); } else { myclassptr.reset(new MyClass<double>()); } myclassptr->foobar(); boost::variant would be another...
spring batch rowNum does not increase
java,spring-batch,mapper,late-binding,rownum
The meaning of the Scope = "step" is that it create a instance for each step of execution which means that you will have a new instance for each thread. So what should be happening is, once you define "step" scope, the map row is called by a new instance...
How do I check enum property when the property is obtained from dynamic in C#?
c#,.net,dynamic,enums,late-binding
In the side assembly: enum ColorEnum { Red, Green, Blue }; We know that Red exists, but nothing about other colors. So we redefine the enum in our assembly with known values only. enum KnownColorEnum // in your assembly { Red }; Therefore we can perform parsing: public static KnownColorEnum?...
Interface, Abstract Class and Methods of Abstract Class
java,oop,interface,abstract-class,late-binding
The reason why you can't see the method there is because your c object is declared as a Car interface. Granted, when it comes out of your factory method, it is a SmallCar, but your variable there is only the interface. You could either change your declaration to AbstractCar c...
How to resolve Missing Powerpoint 15 Object Library Error
excel,excel-vba,powerpoint-vba,late-binding
The library can not be installed just by itself. The simpler way in this situation is to use late binding in your code which should remove the library dependency. Here is a good primer on the differences between early and late binding.
How to initialize user control sub controls when late binding
vb.net,winforms,user-controls,late-binding
When you get a NullReferenceException, it probably means that objAssembly.CreateInstance returned Nothing because it could not find the type you requested (check this using the debugger). Make sure you specify the type name correct. If your control MyControl is inside a module Test inside a namespace MyLib (just some random...
Late Binding vs. Early Binding with Embedded Word Documents
vba,excel-vba,late-binding,early-binding
First, ensure you're using Option Explicit in the code module. THen, when you attempt to compile, it should alert you to a problem with wdFormatOriginalFormatting. Why? wdFormatOriginalFormatting is an enumerated constant within the Word object model. It doesn't exist in Excel, unless you use early binding. Solution When you use...
Outlook COM: Invoke OpenSharedItem via late binding
You need to pass a namesapce object instead of the outlookApp: namespaceObjType.InvokeMember("OpenSharedObject", System.Reflection.BindingFlags.InvokeMethod, null, namespaceObj, new object[] { temporaryFileName }); Anyway, the Namespace class doesn't provide the OpenSharedObject moded. Are you interested in the OpenSharedItem method?...
