Therefore, the method used to call the object through the method (or attribute) name is, you must call the getidsofnames method of idispatch to convert the method (or attribute) name to an ID before calling the object method through the invoke method of idispatch. To facilitate operations, three functions are encapsulated to call the methods of the webbrowser object, read the attributes of the object, and set the a

Multiple data values returned by com

To return multiple data in COM, you can use the safearray and icollection methods. I have not considered other methods. Multiple data returned using safearray is not very flexible, and safearray is not very convenient in other languages, especially in Javascript, to process safearray, it is still a very troublesome thing. At the same time, safearray needs to specially process the data structure to be processed, which should be considered a hassle. It is relatively convenient to return

VBS two ways to create regular expression objects _vbs

All along, I used the New RegExp to create regular expression objects: Set regex = new RegExp However, it is also possible to create a regular expression object that is new to the VBS: Set regex = CreateObject ("VBScript.RegExp") it seems that none of the VBScript books I've read has been written about this, and of course there's still a lot of stuff that's not on the books. Now that a regular expression is mentioned, by the way, the regular expression object of VBS supports MultiLine mode, and

Effective use and design of COM smart pointer-Clause 5: Understand behind the design of _ com_ptr_t

Article 5: Learn about the historical reasons behind the _ com_ptr_t Design_ Com_ptr_t is a proprietary template class of Microsoft in VC. It encapsulates the QueryInterface (), AddRef (), and Release () operations of IUnknown, and provides some member functions to operate COM interface pointers. At the same time, _ com_ptr_t also simplifies the operations of the COM interface on reference count and query operations between different interfaces. To use the smart pointer _ com_ptr_t, you must fir

type. Sometimes, we usually consider the portability and compatibility of a class when considering its design. This leads us to exercise caution when using compiler-related features. Or more often, we can avoid some of the features that the compiler brings to us to pursue portability and compatibility with different platforms. However, before considering these problems, we should first consider the proper execution of the program. A program that allows errors, even if it can be transplanted at
