VFP ListBoxes: Right-Click with Multiple Selections

Something to be aware of if you like to use right-clicks with list boxes in Visual FoxPro.
 
VFP doesn't act like other applications in the way it responds to right-clicks in list boxes.
 
If you turn multi-select on, select multiple items and then right-click on one, only the item right under the mouse will remain selected.
 
This is unfortunate because it means you can't do a right-click action on multiple selections in a list box.
 
Solution?
 
Use the MS Forms List ActiveX control instead. The difference is that you need to use the MouseUp method (since it doesn't have the RightClick method)
 
The control is Forms.Listbox.1 so you can do a createobject("Forms.listbox.1")
 
Subclass this control into your main foundation class and you can create your own RightClick method so none of your other code needs to change.
 
Other changes?
The Listbox uses a Font object (instead of FontName, FontSize). So either get used to using the Font object (Font.Name, Font.Size, etc) or create your own FontName and FontSize properties with access and assign methods.
 
PROCEDURE FontName_Assign (tcFont)
 
THIS.FontName = tcFont
THIS.Font.Name = tcFont

Elevating Project Specifications with Three Insightful ChatGPT Prompts

For developers and testers, ChatGPT, the freely accessible tool from OpenAI, is game-changing. If you want to learn a new programming language, ask for samples or have it convert your existing code. This can be done in Visual Studio Code (using GitHub CoPilot) or directly in the ChatGPT app or web site.  If you’re a tester, ChatGPT can write a test spec or actual test code (if you use Jest or Cypress) based on existing code, copied and pasted into the input area. But ChatGPT can be of huge value for analysts (whether system or business) who need to validate their needs. There’s often a disconnect between developers and analysts. Analysts complain that developers don’t build what they asked for or ask too many questions. Developers complain that analysts haven’t thought of obvious things. In these situations, ChatGPT can be a great intermediary. At its worst, it forces you to think about and then discount obvious issues. At best, it clarifies the needs into documented requirements. ...

Blogs and RSS come to Microsoft.com

MS has just introduced their portal and it's pretty comprehensive. Nothing quite like learning that some people use AIM instead of MSN messenger, or that there really may be a need for supporting 4 monitors ( Cyrus Complains ) However, it's really a great sign that MS is serious about supporting the blogging community which seems to have um, exploded in size in the past year.

I’m Supposed to Know

https://programmingzen.com/im-supposed-to-know/ Great post for developers who are struggling with unrealistic expectations of what they should know and what they shouldn't. Thirty-forty years ago, it was possible to know a lot about a certain environment - that environment was MS-DOS (for non Mac/UNIX systems). . There was pretty much only a handful of ways to get things going. Enter networking. That added a new wrinkle to how systems worked. Networks back then were finicky. One of my first jobs was working on a 3COM + LAN and it then migrated to LAN Manager. Enter Windows or the graphical user interface. The best depiction of the complexity Windows (OS/2, Windows NT, etc) introduced that I recall was by Charles Petzold (if memory serves) at a local user group meeting. He invited a bunch of people on the stage and then acted as the Windows "Colonel", a nice play on kernel. Each person had a role but to complete their job they always had to pass things back to h...
