CobView is a shell context menu extension used to quickly access the properties of the selected files. This is a replacement for the old QuickView utility, but much more powerful due to its plug-in architecture.
You can access CobView when you right click any file or folder on your computer. The program analyzes the file extension and starts the right plug-in to view the file.
Some standard plug-ins show, for example, text files with syntax highlighting (Pascal, c++, java, html, etc), the exported and imported functions of a dll or exe file, the ID3 tags of a mp3 file, and many more...
*****Creating CobView plugins*****
If you are a developer, you may want to create your own plug-in. If you create a cool plug-in and want to publish it, please, send it to me to [email protected] and I will put it on the program's site.
I am NOT responsible for any 3rd parts plug-in. You, as the plug-in author are the responsible for your plug-in functionality and support.
How does it work?
CobView is a shell extension in the form of a context menu that shows when the user right clicks on any file or folder on Windows Explorer. When the user clicks on CobView, the following actions happen:
*The program CobView.exe is loaded.
*This program search the registry on the key HKEY_LOCAL_MACHINE\SOFTWARE\Cobian\CobView\Ext where the associations are stored.
*If the extension of the selected file is found there, the associated plugin is called and the file name is passed to it.
*If the extension is NOT found on the registry, the CobGeneral.dll plugin is called then.
As a plug-in developer you can create your plug-ins in any language you want.
A plug-in MUST have 2 exported procedures with a fixed format.
All other procedures and functions are free. You can download a plug-in example here.
The two obligatory procedures that must be present on a plug-in are:
The first procedure is used to register the extensions by the program CobReg.exe. An example in Delphi of what this procedure may do is:
DllName:array[0..MAX_PATH] of char;
//Register the extensions that the DLL handles
if Reg.OpenKey ('SoftWare\Cobian\CobView\Ext\',true) then
In this example, the program will register the extensions ex1 and ex2 to be open with your plug-in.
The second procedure will receive the file name as a PChar and it is up to you what to do with this file name. I recommend you to download the sample program from my site.
*Your plug-in may include a readme file with your Copyright and other legal information. (for example that YOU are the responsible for your plug-in as the author)
*If you store some configuration keys on the registry, please use the key HKEY_CURRENT_USER\Software\Cobian\CobView\Plugins\YourPlugin where YourPlugin is your plug-in name. *See the Delphi example on my site.
*You can provide your own about box, but you can use my standard box for plug-ins by passing to it your own information. See again the Delphi example.
