Introduction in the Use of Delphi development applications, usually we want to design a lot of documents in various formats, reports, often to create, edit and modify the file, although Delphi itself provides a lot of design report control or method, but there are obvious shortcomings, such

One of the hardest things to do when writing an application with multiple languages and tools is to create and maintain interfaces to the definition file. Luckily, C++builder has done all this for you. When adding one to a project. Pas file, C++builder automatically creates a. hpp file. In the CPP file, you can invoke Pascal's functions, objects, and so on. This provides a convenient way for the programmers of Delphi to transplant all or part of the

cannot directly access other interfaces through one interface. However, COM allows customers to call QueryInterface () in the com library to query other interfaces supported by component objects. In this sense, the component object is a bit like the broker of the interface object.After QueryInterface () is called, if the component object supports the interface to be queried, QueryInterface () returns a pointer to this interface. If the component object does not support this interface, QueryInte

Whether Delphi can develop a Windows Driver (the driver here does not refer to VxD ^_^) has always been a concern of the majority of Delphi fans. Let's stop talking about whether the driver can be used or not. Let's take a look at the technical issues that need to be addressed when developing the driver with Delphi. Delphi's linker cannot generate Windows kernel-

Windows system. COM technology embedded in Word Word is the best software for COM technology, which seems to be a bit extreme, but the powerful programming interface technology that Word provides can be that we control any part of Word by program. Whether it's open, save, print, or automatically draw a table in a document. Through programming software, can be flexible to manipulate word, here only to Borland Delphi For example, for detailed descri

Just contact the Delphi friend, perhaps the most interesting is its rich, powerful VCL (visual Component Library). It's exciting to just throw a few widgets on a form, and even without writing code, it's easy to make a useful program.

Chapter 5 Package In our daily life, we will use all kinds of bags, including wallet, briefcase, backpack, and schoolbag ......, The package contains frequently used items. Once you leave the house that day, you can bring the bag with it. You don't need to consider the specific items in the package, even though some items in the package are needed. With these packages, you can travel easily. Of course, poor packaging or too many packages will become cumbersome.Similarly, in
