The FileSystem and File Controls

The Microsoft FileSystem and File controls are distributed with the platform SDK for each CE platform. They are both included in the MSCEFile.dll library. Controls are added to projects in eVB in the same manner as in other versions of Visual Basic (by choosing Components from the Tools menu). You can add the File and FileSystem controls specifically to your project via the Microsoft CE FileSystem Control 3.0 component library (see Figure 3.1).

Adding the reference places both controls into the eVB toolbox. The File control's button shows a small file icon, whereas the FileSystem control shows a small two-drawer filing cabinet (see Figure 3.2).

The Controls' Object Models

This chapter will cover a large amount of the File and FileSystem controls' object models. Covering the entire object model for any library in a single project is difficult and often impractical. Many methods are used in just about every project, whereas others are used only for specific, narrowly focused uses.

The following is a list of the methods and properties used in this chapter:

As a reference guide, Appendix A includes all the object models for the File and FileSystem controls.
