The Common Dialog/Direct component provides you with a more functional
version of the Common Dialog control which also means you no longer need a form to create
Common Dialogs. These samples show how you can go one further with your app and remove
the need to ship any DLLs at all!
The Harder They Come
There are two ways to do this: the "minimum code" way and the "full compatibility"
version. The minimum code solution means you just need one class in your application: but
you loose the ability to use Hooks to centre and customise dialogs and you get a simplified
interface to work with. The full compatibility version, on the other hand, means you need
to add three classes and one module to your application, but it provides 100% of the functions
provided by the DLL.
I'll cover these in turn.
The Minimum Code Way
In this version code is combined from various parts of the CommonDialog/Direct DLL and the
support for Hooks and Templates removed. The result is a single class cCommonDialog.bas which
offers the following functions:
These functions are equivalent to the Show.. methods of the Common Dialog but with
all the properties supplied as parameters rather than being individually set through properties.
The Minimum Code Single Exe Demonstration project demonstrates opening and saving a document
using this method.
The Full Compatibility Way
This method simply involves copying all the code from the CommonDialog/Direct library into a
project, and ignoring any error messages from VB "Class xxx cannot be public in this type of project, type changed to private".
The Full Function Single Exe Demonstration above shows a sample which uses a hook to
centre a File Open Dialog box.
