Visual FoxPro Scrollbar Classes

New Found Respect for Scrollbar CreationEarlier this evening I decided to create a scrollbar class for use with Visual FoxPro. My requirements were that it was created purely with Visual FoxPro (didn’t have any ActiveX dependecies) and that it was professional enough for use in a real world Visual FoxPro application. It is now five hours later… the class is complete and I have a […]

Visual FoxPro Progress Bar Class

Progress bars everywhere you lookI’ve created Visual FoxPro progress bars before (who among us hasn’t right?). The last time I developed one, I posted it over in the download section of Universal Thread. It is a COM server progress bar that allows progress indication to smoothly continue even when Visual FoxPro is busy churning away on a single line of code. But in today’s […]

Visual FoxPro Grid – A Tip and a Calendar Class

Visual FoxPro’s GridIt is my opinion that the Visual FoxPro grid has gotten a bum rap at times. Though it does possess it’s share of eccentricities, it is probably one of the most powerful and useful controls I have ever had the pleasure of working with. The things that it is capable of doing are simply amazing. Heck, you can […]

Fox Quotes for The FoxShow

Andrew MacNeill of AKSEL Solutions has been doing a stellar job with The FoxShow podcast. If you’re a Visual FoxPro developer, you’ll find his podcasts informative and useful. The topics run the gamut and it’s one of the most ingenious forms of homegrown PR work for Visual FoxPro that I’ve seen in some time. It definitely deserves the Visual FoxPro Community’s support, and on […]

Undocument SYS() Functions

Most of what I’m about to show is more oddity than useful. There are a number of undocumented functions, commands, and other oddities (remember the mousewheel event being used to create a workable systray class?) in Visual FoxPro. From time to time developers will run into them while testing, or someone on the MS Fox Team will mention them, or Visual […]

Rubberband Selections in Visual FoxPro

The day before yesterday I was surfing my blogroll and came across an interesting post by Calvin Hsia — “Enable crop and zooming in on your digital photograph display form“. It was using GDI+ in a Visual FoxPro form and, since I am writing a series of articles for FoxTalk on the subject, it caught my eye. One of the […]

Splitter Class for Visual FoxPro

A number of other languages have a splitter control of some sort, why not Visual FoxPro? To be fair, I have seen some splitter classes floating around from time to time, but I thought I’d try my hand at it. I was convinced it couldn’t be too difficult, and Visual FoxPro didn’t disappoint me. Below is a download link for […]
