http://www.codeproject.com/tips/vcgallery.asp
Introduction
Sometimes, gentle reader, you may wish to use the same code in many projects (an honorable and just practice) and for reasons best left to yourself you choose not to partake in the creation of lib files and dll’s.
In fact many programmers choose to create a directory and dump classes (the .h and cpp files), which they think they may use often, and then add the relevant paths to VC++ (Tools->Options->Directories then setting the relevant include and source directories as necessary). Moreover other programmers like to simply dump a copy of the .h an .cpp files into the project folder they want to use it in and work from there. And still others yet like to use the Gallery to create ogx files. The purpose of this article then, gentle reader, is to elucidate as to how to take advantage of the Gallery.
A Beginning
Suppose my friend, you have created a most excellent class that you believe you will want to use in another project. You don’t wish to use dll’s or lib files. Perhaps each time you need to use it some minor modification may be necessary or perhaps even you dear reader just simply want access to the source code in the project without having to go dropping copies of the source code around into folders.
A very lithesome ion to this problem is provided by using the Gallery. According to the help files provided by Microsoft™…
The Gallery provides a convenient way to add complex code such as components and ActiveX controls to your project, or to let you reuse previously written code.”
But how do we add our class(es) to this magical Gallery?
Simple my good friend – follow this gentle procedure.
Open the project in which the class of interest already exists.
Open the Workspace (View Menu->Wordspace, or ALT-0)
Click on the root node of the Tree (in this case “MyCoolApp classes”) and there will now be a list of the classes in the application (see below).
Click on the class of interest (in this case we will use “CMyGroovyClass” and from the menu displayed choose “Add to Gallery”).
This will now create a nice sparkly new folder in something like “C:\Program Files\Microsoft Visual Studio\Common\MSDEV98\Gallery” (depending on where you have VC++ installed). The folder will have the same name as the project (in this case “MyCoolApp”) and inside this folder will be a .ogx file with the same name as your class (in this case it will be My Groovy Class.ogx (see below)
You can share this file with others if you wish. To use it, all they need to do is either create a similar sub-folder in the Gallery folder and place the .ogx file into that, or they can drop the file into “Visual C++ Components” folder (Although it is probably best if they create a new folder).
Now what?
Now you have added your class to the Gallery, you are now free to use it in other projects with little effort to you dear reader.
How do I use it?
Open the project you want to add the class to (or start a new project).
Open the Gallery (Project Menu-> Add to Project->Components and Controls)
From the “Components and Controls Gallery” window that appears, select the folder that holds the .ogx (in this case MyCoolApp).
Then either double click the .ogx file, or select the .ogx file then click “Insert”, you will now be prompted with the following dialog:
Click “OK”, then close the “Components and Controls Gallery” window. The class will now be inserted into your project (just like magic but better).
Having passed on my wisdom I am now free to go about my daily business as too are you my dear reader. I hope this has been enlightening and wish you happiness and heartiness on your quest for perfect programming
An additional pointer to you all in your journey - You can also add ActiveX controls or third party components to your projects. Read the MSDN help files for information on how to do this and for more information on .ogx files.
Here-in ends the lesson.
