Cogetobject

helpful tips or sample code to share for using this API in managed code? I've moved over to BlogEngine.Net for my blogging software. When the client has finished working with the object, the object must be released, along with the bind context and the moniker itself. In what a difference between functions CoGetObject and CoGetClassObject, except an amount and types of input parameters?

My primary source of documentation was MSDN. So this redux article attempts to trace back through my learning about IUnknown, IDispatch and the use of Invoke to execute method calls. It depends only on your preference. Names are used throughout Windows to identify everything from files to event objects.

Dev centers Windows Office Visual Studio Microsoft Azure More... That makes a grand total of 23 methods required to implement a custom moniker. ppv [out] The address of a pointer to the interface specified by riid on the object that is created. For example, using the BIND_OPTS2 structure, you can set the pServerInfo member to point to a COSERVERINFO structure containing the name of the machine on which the binding operation should occur.4

Instead of using a CLSID or marshaled interface pointer, monikers employ a somewhat user-friendly string called a display name to identify COM+ objects. Requirements OS Versions: Windows CE 3.0 and later. If that's done properly, your ParseDisplayName() will get called again with the rest of the string. my site Friday, June 6, 2008 VB Script, GetObject, C++, API, CoGetObject In my last post, I asked a couple of questions regarding this statement Set IIsObject = GetObject ("IIS://localhost/w3svc"): How do you

C# Signature: [DllImport("ole32.dll", CharSet=CharSet.Unicode, ExactSpelling=true, PreserveSig=false)] [return: MarshalAs(UnmanagedType.Interface)] static extern object CoGetObject( string pszName, [In] ref BIND_OPTS pBindOptions, [In, MarshalAs(UnmanagedType.LPStruct)] Guid riid); User-Defined Types: BIND_OPTS Notes: None. Item moniker CreateItemMoniker An item moniker identifies an object contained in another object.

How on earth is this related to monikers? http://www.vbforums.com/showthread.php?743649-How-to-use-the-CoGetObject-API-function-in-VB6 I was able to manipulate some attributes in C# to exposed the methods with proper ID numbers. (This project is also why I switched to managed C++ for most of my If, as is the case with pointer monikers, certain methods of an interface simply are not relevant to a specific implementation, this might indicate that the interface was designed improperly. I do the following: #import "DocView.tlb" no_namespace ...

Figure 11-2 shows the registry entries involved in this hypothetical example; the numbered labels indicate the order in which the information is obtained from the registry. You can do this by creating an explicit bind context and then calling the IMoniker::BindToObject method; or you can use the BindMoniker helper function discussed previously. Using ABO does not follow my thought process while learning how to manipulate COM.

COM> Date: 1998-08-04 20:11:21 [Download message RAW] The most obvious thing that jumps out at me is that after you find the progID you need to update *pchEaten, convert the progID The key questions I wanted to answer are:How do you open the "IIS://LocalHost/w3svc" object in C++?What is the C++ equivalent to GetObject?The trick is to answer the second question first. DISPPARAMS dispparamsNoArgs = {NULL, NULL, 0, 0};bstrMethodName = _T("AnonymousUserName"); if (FAILED(hr = pDispatch->GetIDsOfNames(IID_NULL, &bstrMethodName, 1, LOCALE_USER_DEFAULT, &dispid))) { // Normally, we would decompose hr to obtain more error information It works.

This parameter can be a null string ("") if szProgID is non-null. For details, see BIND_OPTS. For example, if the string "Hello:Maya" is passed to MkParseDisplayName, the HKEY_CLASSES_ROOT section of the registry is searched for the ProgID Hello.

I will show you in the future how to request the IDispatch interface and how to call the method Get using Invoke, just as VB does.

Monikers are the answer to the first question, and consequently they provide the answer to the second question. There is some sample code you can actually run and step through. -Rob At 03:20 PM 8/4/98 -0400, you wrote: >May be!! IMyInterface* pMyInterface; pMoniker->BindToObject(pBindCtx, NULL, IID_IMyInterface,      (void**)&pMyInterface); Once a moniker is bound to the underlying object that it names, a pointer to the requested interface of that object is returned to the client application. Many of the software systems we write today must interact with legacy software, including scripting.

If Hello is found, the CLSID subkey below the ProgID is used to locate and load the moniker. We want the IDispatch interface, not the IADs interface. MK_E_NOOBJECT The object identified by this moniker, or some object identified by the composite moniker of which this moniker is a part, could not be found. This design flaw is more annoyance than limitation, but it does illustrate the importance of careful interface design.
