Hi, DISP_FUNCTION_ID : You should define dispatching map for any method in ActiveX to be used for COM. If the map is not set correctly,Method will not be seen anymore. DISP_FUNCTION_ID gets 6 parameters.These are; 1-class,method belongs to 2-External Method name,value can be method name 3-Dispatch id of method,unique number 4-Method 5- Return value should be one of VARENUM in wtypes.h 6- Parameters value defines in afxdisp.h (space is seperator of each params) for example; DISP_FUNCTION_ID(C_X_OleLibraryCtrl, "GetIDLMsg", 1, GetIDLMsg, VT_BSTR /* return type*/, VTS_PVARIANT VTS_BSTR /* two parameters are seperated by empty*/) good luck, P.S. If you have any comments please do not hesitate share.

Hi, I would like to share a project based on Linux for building Laptop or Desktop more secure; QubesOS. Project Qubes aims at building a secure operating system for desktop and laptop computers. The stress is on security, which is achieved by exploiting the isolation capabilities of the bare-metal hypervisor (Xen), together with modern hardware technologies, such as Intel VT-d and Trusted Execution Technology. Problems with current operating Systems: Current mainstream operating systems that are used for desktop computing, e.g. Windows, Mac OS X, or Linux-based systems, proved unsatisfactory when it comes to security. The major problem with current systems is their inability to provide effective isolation between various programs running on one machine. E.g. if the userʼs Web browser gets compromised (due to a bug exploited by a malicious web site), the OS is usually unable to protect other userʼs applications and data from also being compromised. Similarly, if certain system core comp

Hi, if you are looking asynchronous method call to use in Windows Service .You are correct way.Asynchronous methods call is useful in windows service. First of all create delegate; public delegate void OnStartDelegate(); secondly create asynchronous call method; private void OnStartCallback(IAsyncResult ar) { ((OnStartDelegate)ar.AsyncState).EndInvoke(ar); } then use them in Start (or stop or anywhere you want) method like; OnStartDelegate OnStartDelegateInst; OnStartDelegateInst = new OnStartDelegate(OnStartAsynch); OnStartDelegateInst.BeginInvoke(OnStartCallback, OnStartDelegateInst); best wishes...
