Comments
The OleLockRunning function saves you the trouble of calling the IRunnableObject::LockRunning method. You can use OleLockRunning and IRunnableObject::LockRunning interchangeably. OleLockRunning queries for an IRunnableObject pointer. If successful, it returns the results of calling IRunnableObject::LockRunning.
Note The implementation of OleLockRunning in earlier versions of OLE differs from that described here.
For more information on using this function, see IRunnableObject::LockRunning.

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
