I want to invoke GetClientSite on a .net control. For this purpose I am trying to cast a control (in example Windows.Forms.Form) to IOleObject which returns null. What should I do to get IOleObject? using System; using System.Runtime.InteropServices; using System.Security; using System.Windows.Forms; namespace Test001 { public class Form001 : Form { public Form001() { InitializeComponent(); } private void InitializeComponent() { this.SuspendLayout(); this.Name = "Form001"; this.Text = "Form001"; this.Load += new System.EventHandler(this.Form001_Load); this.ResumeLayout(false); } private void

I have a C# COM DLL that defines some interfaces/types that I use from a C++ ATL/COM server. From time to time, be it on my machine, or randomly on other machines where I build the same projects (the ATL *.exe and the C# DLL) I get different compile errors related to exported C# struct members that are part of the COM interface. Here is an example: public enum TemporaryPolicyType { UntilTime = 0, ForNextMinutes } [Guid("6F8CD968-DA76-44CA-B4E1-C495AB5003BD")] public struct TemporaryPolicyData { public TemporaryPolicyType Type; public DateTime Timestamp; public DateTime EndTime; public int

Then go to definition of it, which will take us to Metadata. we can note down the GUID and then search it in registry, if that is available, like this one. namespace NETWORKLIST { [ClassInterface(0)] [Guid("DCB00C01-570F-4A9B-8D69-199FDBA5723B")] [ComSourceInterfaces("NETWORKLIST.INetworkEvents")] 来源： https://stackoverflow.com/questions/20301820

I have write the following code in COM client in separate thread while(not we are

I have encountered an issue when using Windows Update Agent (WUA) API. Whenever I try to uninstall an update using IUpdateInstaller.IsForced := True; IUpdateInstaller.BeginUninstall(... i'm getting WU_E_UNINSTALL_NOT_ALLOWED ( The update could not be uninstalled because the request did not originate from a WSUS server ). Does it mean that I can't use WUA API to uninstall updates? In that case, why are BeginUninstall/Uninstall methods there? According to Hey, Scripting Guy! How Can I Remove a Microsoft Update? (and also here ) the WUA API can only be used to uninstall updates that were
