interop

问题 I am trying to acquire state of a checkbox existing in an XLS document via C#. Let me back up here. This is what I have: MS Office 2007 + Dev Tools and VC# 2010 Express Referenced MS Excel 12.0 Object Library An XLS document I successfully retrieve the Excel.Shape object. However, I am stuck when trying to determine whether it is checked or not. So far I have acquired its AutoShapeType, which says msoShapeMixed. Can someone point me to the right direction? Thanks! class Program { static void

问题 So, my Java application reveives some data that is generated with PHP's gzdeflate(). Now i'm trying to inflate that data with Java. This is what i've got so far: InflaterInputStream inflInstream = new InflaterInputStream(new ByteArrayInputStream(inputData.getBytes() ), new Inflater()); byte bytes[] = new byte[1024]; while (true) { int length = inflInstream.read(bytes, 0, 1024); if (length == -1) break; System.out.write(bytes, 0, length); } 'inputData' is a String containing the deflated data.

问题 I have an unmanaged library which has a function like this: type* foo(); foo basically allocates an instance of the unmanaged type on the managed heap through Marshal.AllocHGlobal . I have a managed version of type . It's not blittable but I have MarshalAs attributes set on members so I can use Marshal.PtrToStructure to get a managed version of it. But having to wrap calls to foo with extra bookkeeping to call Marshal.PtrToStructure is a bit annoying. I'd like to be able to do something like

问题 My .net code has an object with a number of generic properties. This object is returned to the VBA code. All the non-generic properties are working well, but I also need to access the generic values. Is there a way to do it from VBA? [ClassInterface(ClassInterfaceType.AutoDual)] public class Obj { public string GetProp1() {...} public IList<MyCustomType> GetProp2() {...} } VB code: Sub Test() Dim o As Program.Obj Set o = New Program.Obj Set p2 = hp.GetProp2() set p2_0 = p2(0) ' doesn't work

问题 We are working on an integration of a large MFC-based application with a handful of managed (.NET) add-ins. Communication with these add-ins is done via COM. Historically, we've just used the registry to make these add-ins available (as COM servers) to the application. But, now we're trying to use registration-free COM interop to do this. We'd like these add-ins to be able to live in a separate directory from the one that the application is running in -- ideally anywhere. But, we're

问题 I have been experimenting with C++/CLI delegates (as I am trying to make a .NET reference library), and I have been having the following problem. I define a delegate in C++/CLI, and then create an instance of the delegate in C#, and then call the instance of the delegate through unmanaged C++ via a function pointer. This all works as expected. Code to illustrate this (first my C#) using System; namespace TestProgram { class Program { static void Main(string[] args) { Library.Test
