Note: This utility can potentially disable your treasured source code if not properly used (read if you wack the code without knowledge of the internals of the SCX/VCXs you can disable the file).  Use this tool on backup copies of the source (or backup the code before hacking) so you safely make changes.  I take no responsibility for use of this product.

This utility I wrote is called "RAS Hack VCX/SCX". Have you ever renamed a Visual Class Library? I can already hear the groans and see the looks of terror on the faces of all the developers who read this line. What happens next? Try opening a Form that has objects you renamed in the class library. "Error instantiating class. Cannot find <classname> in <class library>". Sure you can locate the renamed classes and the form is displayed in the Form Designer. Close the form, open it up again and see that the locate dialog is presented again. Even though you pointed the object to the right class the Form Designer never noted the form changed to kick in the Save logic when closed down. Nice, huh? Sounds like a bug to me. Make another change to the form to work around this. Even more aggravating than this is that every object that was renamed (or if the class library was renamed) will spawn the locate dialog. The same dialog is displayed over and over even if the new class or class library were located before. This can be quite frustrating after the first 5 or so changes.

So what happens when something does go wrong and you just need to get inside the .VCX or .SCX? One can USE the file and browse it. Unfortunately all the stuff you want to see is in memo fields. Now you have to start looking for all the fields you want to look into, resize them, move them to another place so the information is viewable, etc. The next time you open it up with a BROWSE LAST you will be okay, but a new class will cause you this grief all over again!

I built the Hack VCX/SCX form to get around some of the configuration frustrations that came along with the BROWSE technique. This form allows you to select a Form or Visual Class Library. It opens it and displays the information inside the file. I protected some of the fields I felt I had no business changing at all. The rest are open to modify to my hearts content (or until I can disable the file all together).

Version 3.0 (viewed in VFP 7)

This tool was originally presented in the July 1997 issue of FoxTalk as part of my article Using VFP 5.0 Top-Level Forms.
