In what a difference between functions CoGetObject and CoGetClassObject, except an amount and types of input parameters?

The CoGetObject Helper Function Once you obtain an IMoniker interface pointer using MkParseDisplayName, the next step is typically to bind to the object named by the moniker. The most common reasons for returning this value are that a password is needed or that a floppy needs to be mounted. 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

MK_E_CONNECTMANUALLY The binding operation requires assistance from the end user. Copy WINOLEAPI CoGetObject( LPCWSTR pszName, BIND_OPTS* pBindOptions, REFIID riid, void** ppv ); Parameters pszName [in] Display name, in string format, of the object to be created. The moniker's IParseDisplayName::ParseDisplayName method is then called to create a moniker object that names the Maya object. Originally Posted by Arnoutdv The first parameter in CoGetObject is the fully qualified path name for the ActiveX EXE, not the name of your Excel file.

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 The first step is to gain access to the Active Directory COM object. Then I performed a query interface call to confirm that IADs was supported.

Dev centers Windows Office Visual Studio Microsoft Azure More... I would learn how to reproduce the functionality of the scripts using C++, COM and WTL templates.

The time now is 01:41 PM. if (FAILED(hr = pUnk.QueryInterface(&pDispatch))) { // Normally, we would decompose hr to obtain more error information MessageBox(_T("Unable to obtain pointer to IDispatch interface."), _T("Error"), MB_ICONERROR); return TRUE; }What The template is able // to use the type information used while declaring pDispatch to simplify // the call. The IParseDisplayName::ParseDisplayName method is called to parse the string passed to MkParseDisplayName.

I think it might be in MSDN or otherwise www.microsoft.com/msj. riid [in] Reference to the ID of an interface that is implemented on the object to be created. This documentation is archived and is not being maintained. Well, actually, most Visual Basic programmers know the MkParseDisplayName function by a different moniker--they call it GetObject.

The template call // has greatly simplified the QueryInterface call. Code: Option Explicit Private Declare Function IIDFromString Lib "ole32.dll" (ByVal lpsz As Long, ByRef lpiid As Any) As Long Private Declare Function CoGetObject Lib "ole32.dll" (ByVal pszName As Long, ByRef pBindOptions 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 But I am lazy and I don't want to implement the code necessary for Invoke. (We sometimes call this late binding.

To create a page in a module other than ole32, prefix the name with the module name and a period. As per MSDN the first parameter is the display name of the object to be created. This documentation is archived and is not being maintained.

In some situations, a bind context enables certain optimizations to occur during the binding of composite monikers.

IMoniker Method Description BindToObject Binds to the object named by the moniker BindToStorage Binds to the object's storage Reduce Reduces the moniker to its simplest form ComposeWith Combines the moniker with Names are used throughout Windows to identify everything from files to event objects. The second string format is the more general and thus more important of the two formats. The same as in GetObject.

Instead, the J/Direct feature of the Microsoft Java Virtual Machine (VM) enables Java programs to call native Win32 API functions; you can use it to directly invoke the standard CoGetObject function. The first parameter in CoGetObject is the fully qualified path name for the ActiveX EXE, not the name of your Excel file. Or the pointer on a heap of garbage. Once we have a pointer to IDispatch, we can call any methods and properties exposed in this interface.

But this is a different story.) ScrewTurn Wiki version 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. Return Values This function supports the standard return values E_FAIL, E_OUTOFMEMORY and E_UNEXPECTED, as well as the following: S_OK The object was created successfully. Made approximately as.And nevertheless a question.

Register Help Remember Me? This design flaw is more annoyance than limitation, but it does illustrate the importance of careful interface design. What if you need to expose a custom interface, instead of the standard stuff exposed by the CCW?

Summary Converts a display name into a moniker that identifies the object named, and then binds to the object identified by the moniker. We appreciate your feedback. I realized while writing the article that I had taken some intellectual shortcuts.
