This article is a problem encountered in the actual development process. I have received help from my colleagues and would like to thank you. In the secondary development process of SolidWorks, the asynchronous mode is used, and the following code

The COM interface IFoo implemented in the C Implementation COM interface Series 1 is coupled with the customers who use it, without implementing the modules that are separate from each other, and therefore does not conform to modular programming

The Microsoft agent has a fairly wide range of uses that we can either add to a common application for use by the local system, or embed it in an HTML document for internet/intranet use. The Microsoft agent supports a variety of programming

Compiling the generated program from the VS-created Windows Service project and registering it as a Windows service through the command line "service. Exe-service" can be managed through the Service manager. Problem The discovery service failed to

Ccomobjectrootobjectbase provides an internal implementation of interface query in table-driven mode, that is, internalqueryinterface (). Therefore, when creating an ATL-Based Com class, you must create a ing table containing all the Implemented

Through the previous study and practice, we have learned how com is and how to call COM components. To sum up, COM is the component object model, which means that the COM Object and COM class are different from the objects and classes in C ++, VB,

I. BACKGROUND notesIn the eclipse environment, the development of Java code operation PPT, support the modification of PPT template. This includes modifying text labels, charts, and tables. Meet the requirements of most software to generate PPT

Except for basic non-pointer types (such as ing, long, And bool), other parameters passed in through the COM interface must use the specific COM type --For strings, The BSTR type should be used. This type is a fuzzy type. Microsoft does not disclose

Use the COM interface: When you create a COM object, the method for creating a COM Object returns a pointer to the interface. Then you can use the pointer of this interface to access other methods of this interface. The usage of pointers is the same
