问题 My team is tasked with getting several in-house developed .NET client applications to connect to some new Java web services. The Java web service is a third party, vendor supplied WSDL file that our team has a limited ability to modify/control...meaning we probably have the power to request our vendor to make slight tweaks to the WSDL, but major changes would probably be either unfeasible or difficult to request. That said, we are attempting to utilize WCF/.NET 4.0 to generate the .NET proxy

问题 Ok I am trying to connect to an Outlook calendar from C# using the following code: using Outlook = Microsoft.Office.Interop.Outlook; Outlook.Application msOutlook = new Outlook.Application(); Outlook.NameSpace ns = msOutlook.GetNamespace("MAPI"); Outlook.MAPIFolder folder = ns.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar); foreach (Outlook.MAPIFolder subfolder in folder.Folders) { MessageBox.Show(subfolder.Name); } However, despite having two Calendars, the piece of code above

问题 Is it possible to declare different charset options for seperate params? heres what i mean: [dllimport("my.dll", charset = charset.Ansi)] void myfunc(string CharPtrInCPP, StringBuilder WCharPtrInCPP); the problem is the c++ function takes a char* for the filename and a wchar* for the data recieved back... in c++: void myfuncImpl(char *filename, WCHAR *buffer, int len); //another method, myfunc, wraps this 回答1: As already pointed out, you should be able to specify MarshalAs for each parameter.

问题 I need to know all memory address space used by a process. The memory space will later be scanned to locate values within the process and identify their locations / addresses. My current process for this is to take each module's base address through its (base address + memory size). I'm testing this on a process with a known value at a known address. When I look up that specific address, I get the value I expect. However, when I scan (what I believe to be) all address space used by the

问题 When I try and call any method on a COM Object that takes one or more arguments, I get the following error on the last argument: Could not convert argument 0 for call to Open. (ArgumentError) Everything works fine when calling a method that takes no arguments, or getting/setting a property. Here is the code that gives me the error above: def new_com_object(prog_id) System::Activator.CreateInstance(System::Type.GetTypeFromProgID(prog_id)) end xls = new_com_object('Excel.Application') xls

问题 I'm after help on how to use complex objects either as return values or passed as parameters to C# class methods exposed to unmanaged C++ as COM components Here's why: I'm working on a project where we have half a dozen unmanaged C++ applications that each directly access the same Microsoft SQL Server database. We want to be able to use MS-Sql/Oracle/MySql with minimum changes and we've decided to implement a business logic plus data layer exposed via WCF services to get the required
