late-binding

I'm going to give an example of using System.Data.SQLite.DLL which is a mixed assembly with unmanaged code: If I execute this : var assembly= Assembly.LoadFrom("System.Data.SQLite.DLL") No exceptions are thrown, but if I do this : var rawAssembly = File.ReadAllBytes("System.Data.SQLite.DLL"); var assembly = Assembly.Load(rawAssembly); The CLR throws a FileLoadException with "Unverifiable code failed policy check. (Exception from HRESULT: 0x80131402)". Let's say I'm trying to load this assembly on a child AppDomain, how can I customize the AppDomain's security to allow me pass the policy check?

Introduction I am trying to use jobparameters created in a tasklet to create steps following the execution of the tasklet. A tasklet tries to finds some files (findFiles()) and if it finds some files it saves the filenames to a list of strings. In the tasklet I pass the data as following: chunkContext.getStepContext().getStepExecution().getExecutionContext().put("files", fileNames); The next step is a parallel flow where for each file a simple reader-processor-writer step will be executed (if you are interested in how I got there please see my previous question: Spring Batch - Looping a reader

I'm trying to write some code for an add-in in excel, which grabs some data from an SQL Server. The code itself is working flawlessly, but somehow something got corrupted. It seems that the code will work fine a few times and then all of a sudden trigger an excel-crash. After a long time I've determined that it has something to do with the references, seeing as if upon crash I change the reference 'Microsoft ActiveX Data Objects 2.8 Library' to something else, and then back again, the add-in will work again. Seeing as rebuilding the add-in doesn't work, I'm beginning to explore the option of

There is a code: var myobject: OleVariant; begin myobject := CreateOleObject('SomeNamespace.SomeClass'); end; This COM object has events (for example OnClick). How should I connect to these events without importing TLB? You are working with COM late-binding, so do you need write a lot of code to handle events. this task is not difficult if you know COM, basically do you need follow these steps. Create a new object(class) derived from TInterfacedObject that implements IDispatch implement the Invoke() function of your new class Query for the connection point container ( IConnectionpointContainer

We're interfacing to some 3rd party COM objects from a C++Builder 2010 application. Currently we import the type library and generate component wrappers, and then are able to make method calls and access properties in a fairly natural way. object->myProperty = 42; object->doSomething(666); However, we've been bitten by changes to the COM object's interface (which is still being extended and developed) causing our own app to fail because some method GUIDs seem to get invalidated - even if the only change to the interface has been the addition of a new method). Late Binding has been suggested as

I am using knockout.js to display a list of employees. I have a single hidden modal markup on the page. When the "details" button for a single employees is clicked, I want to data-bind that employee to the modal popup. I am using the ko.applyBindings(employee, element) but the problem is when the page loads, it is expecting the modal to start off as bound to something. So I'm wondering, is there a trick/strategy to do a late/deferred databinding? I looked into virtual bindings but the documentation was not helpful enough. Thanks! I would create another observable that wraps the employee. this

The Question My question is: Does C# nativly support late-binding IDispatch? Pretend i'm trying to automate Office, while being compatible with whatever version the customer has installed. In the .NET world if you developed with Office 2000 installed, every developer, and every customer, from now until the end of time, is required to have Office 2000. In the world before .NET, we used COM to talk to Office applications. For example: 1) Use the version independant ProgID "Excel.Application" which resolves to: clsid = {00024500-0000-0000-C000-000000000046} and then using COM, we ask for one of
