Error Creating Instance Of Realguitar
It’s called burn-out. I feel it often. Unfortunately time away doesn’t work for long. Difference between me and you though is my management is great, but I personally feel like I’ve been stonewalled from advancement and just feel stuck.
- Note: The registry is the most important part of the Windows Operating System and stores all information and configuration about how the Windows runs.
- Run RealGuitar Classic, it will ask you to locate soundbank. Point to RealGuitar folder (Acoustic0AC44.mln) on external drive, click OK; Run RealGuitar Steel String, it will ask you to locate soundbank. Point to RealGuitar folder (Steel0AC44.mln) on external drive, click OK.
Creates a single uninitialized object of the class associated with a specified CLSID.
Call CoCreateInstance when you want to create only one object on the local system. To create a single object on a remote system, call the CoCreateInstanceEx function. To create multiple objects based on a single CLSID, call the CoGetClassObject function.
Syntax
Parameters
rclsid
The CLSID associated with the data and code that will be used to create the object.
pUnkOuter
If NULL, indicates that the object is not being created as part of an aggregate. If non-NULL, pointer to the aggregate object's IUnknown interface (the controlling IUnknown).
dwClsContext
Serial virtual dj 8 para mac. Context in which the code that manages the newly created object will run. The values are taken from the enumeration CLSCTX.
riid
A reference to the identifier of the interface to be used to communicate with the object.
ppvVirtual dj xp download.
Address of pointer variable that receives the interface pointer requested in riid. Upon successful return, *ppv contains the requested interface pointer. Upon failure, *ppv contains NULL.
Return value
This function can return the following values.
| Return code | Description |
|---|---|
| An instance of the specified object class was successfully created. |
| A specified class is not registered in the registration database. Also can indicate that the type of server you requested in the CLSCTX enumeration is not registered or the values for the server types in the registry are corrupt. |
| This class cannot be created as part of an aggregate. |
| The specified class does not implement the requested interface, or the controlling IUnknown does not expose the requested interface. |
| The ppv parameter is NULL. |
Remarks
The CoCreateInstance function provides a convenient shortcut by connecting to the class object associated with the specified CLSID, creating an uninitialized instance, and releasing the class object. As such, it encapsulates the following functionality:
It is convenient to use CoCreateInstance when you need to create only a single instance of an object on the local machine. If you are creating an instance on remote computer, call CoCreateInstanceEx. When you are creating multiple instances, it is more efficient to obtain a pointer to the class object's IClassFactory interface and use its methods as needed. In the latter case, you should use the CoGetClassObject function.
In the CLSCTX enumeration, you can specify the type of server used to manage the object. The constants can be CLSCTX_INPROC_SERVER, CLSCTX_INPROC_HANDLER, CLSCTX_LOCAL_SERVER, CLSCTX_REMOTE_SERVER or any combination of these values. The constant CLSCTX_ALL is defined as the combination of all four. For more information about the use of one or a combination of these constants, see CLSCTX.
