WEBUTIL_C_API Demo Form

Question

A number of people have asked me about WEBUTIL_C_API, and I have offered to contribute a simple form that demonstrates how one can use this built-in to access the Windows API.
I have prepared a reasonably simple and straight-forward example, but I am still writing up instructions. I expect to have the demo completed this weekend -- I will post a URL for downloading it, at that time. Please follow this thread for further information.
Thanks,

Answer 1

Francois,
I've placed an updated version of apiwrap.dll & apiwrap.pll at the following URL:
http://www.ericadamson.com/code_samples/oracle_forms/apiwrap.zip
The PLL was created using 10.1.2.0.2 -- users with previous versions will probably need to build apiwrap.pll for themselves. For portability, I've also included the APIWRAP package spec & body as simple text files. Note that apiwrap.pll requires webutil.pll -- don't forget to attach it before compiling!
To save time, this version comes undocumented, but I'm sure you will have no problem figuring everything out! :) For others interested in experimenting with this code, please:
1. Be certain that WebUtil is installed on your app server or OC4J, and functioning correctly
2. Know how to build a WebUtil-enabled form.
3. Know how to compile apiwrap.pll (web forms require PLX's!)
4. Understand how WebUtil copies native DLL's to the client (read <forms_home>\forms\server\webutil.cfg for details)
5. Study the APIWRAP package spec for usage information and helpful constants
6. Refer to the Windows SDK documentation for information on the underlying API calls, FindWindow, ShowWindow, SetWindowText & SetWindowPos. For those who lack Windows SDK documentation, visit http://msdn.microsoft.com and search for the desired function by name, either from the main page, or from the MSDN Library.
