问题 I wrote this function to retrieve all Administrators Members SIDs: private IList<byte[]> GetAdministratorsMembersSIDs() { IList<byte[]> adminMembers = new List<byte[]>(); SecurityIdentifier id = new SecurityIdentifier(administratorsSid); string name = id.Translate(typeof(NTAccount)).Value.Split('\\')[1]; using (DirectoryEntry adminGroupEntry = new DirectoryEntry(string.Format("WinNT://./{0},group", name))) { foreach (object member in (IEnumerable)adminGroupEntry.Invoke("Members")) { using

问题 Is there way to add an if/else catch to only $excelId = get-process excel | %{$_.Id} | ?{$before -notcontains $_} if there is no excel process running? e.g. if Excel is running then get-process id, if not then ignore it. Get-Process : Cannot find a process with the name "excel". Verify the process name and call the cmdlet again. At run.ps1:3 char:24 + $before = @(get-process <<<< excel | %{$_.Id} ) + CategoryInfo : ObjectNotFound: (excel:String) [Get-Process], ProcessCommandException +

I'm using Visual Studio 2015 and have started receiving the following error message. I'm not trying to write dll's or using COM objects or whatever. It's just a simple OpenGL program. I have no idea where this error message has come from. How do I get rid of it? 回答1: You are using COM implicitly. Without code, we don't know exacly.

问题 I'm currently developing a "drop-in" replacement of an old COM interface (which is used to communicate with other devices). This interface is currently used in a big application. The old COM interface is now deprecated by the author of the library they now only support and develop a C# interface. My task is to develop the above mentioned "drop-in" replacement. Which acts as a proxy between the old application (written in Delphi) and the new C# based interface. Im trying to have as little as

问题 I have a DLL (written in C#) containing a class with 2 Constructors; a default (no arguments) constructor, and another one with 3 arguments. In VBscript, I want to call the second constructor, but CreateObject only receives a classValue parameter, no possible arguments parameters. I guess the underlying implementation of CreateObject uses the system's CoCreateObject function, which according to this answer does not support arguments, but on the other hand there's QTP/UFT's DotNetFactory that

问题 I would like to be able to code a class interface which I can implement in C# and VB6 classes so that these classes can be handled in the same way within VB6 code but I can't make this work. In VB6 I want to have come class VB6Class using the Implements key word to implement some interface ISharedInterface. In C# I want to have some other class C#Class which I can expose to COM as also implementing ISharedInterface. The goal is that VB6 code will then be able to operate on VB6Class and C

问题 I'm trying to write a wrapper to ADO. A DECIMAL is one type a COM VARIANT can be, when the VARIANT type is VT_DECIMAL . I'm trying to put it in c native data type, and keep the variable value. it seem that the correct type is long double, but I get "no suitable conversion error". For example: _variant_t v; ... if(v.vt == VT_DECIMAL) { double d = (double)v; //this works but I'm afraid can be loss of data... long double ld1 = (long double)v; //error: more then one conversion from variant to

问题 I have a tlb files that contains some function declaration that I need to use. If I use #import "type_library.tlb" I can correclty reference the function from my code: tlb_namespace::required_function(); But when I compile the project the linker says that tlb_namespace::required_function is an unresolved external symbol. How can I succesfully build this kind of project? EDIT : I have used the same type library in a Dummy VBA access project. I have added the reference to the type library and I
