ActiveX控件 教程
VB应用程序的用户界面主要由控件构成,而在工具箱中只提供了21个标准控件。显然,只使用这些控件编写复杂的应用程序是有困难的。因此,有必要对VB的功能进行扩展,其途径主要有以下三种:
• 利用VB以及第三方开发商为用户提供的大量的ActiveX控件。它们是VB工具箱的扩充,能够大大增强VB的编程功能。
• 使用OLE技术。可以将其他Windows应用程序的对象,如Word文档、Excel图表等插入到VB应用程序中,从而增强VB与其他应用程序共享及传输数据的能力。
• 调用系统API函数。API函数是Windows环境中可供任何Windows应用程序调用的一组函数,可以调用这些函数进行系统控制等操作。
-This VB application user interface consists mainly of control, and the composition of the kit provides only 21 standard controls. Obviously, only use these controls write complicated application is difficult. Therefore, it is necessary to the VB function expansion and its approach has three main types:
, using VB and third-party developers for users provide large amounts of ActiveX controls. They are VB toolbox extended, can greatly enhance the VB programming function.
, use OLE technology. Can other Windows application object, such as Word doc, Excel illustrations etc insert VB app, thereby enhancing the VB and other applications to share and data transmission ability.
, call system API functions. API is Windows environment for any Windows application procedure call a set of functions, which can call these functions systematically control operation.
