So Iâm not sure if I will >keep it, but itâs worth a trial at least. The numbers do not make sense. Does that "100K" mean 100,000 messages or 100 kilobytes? How does 280 relate to 133,000? For testing, I suggest that you send some regular test messages. You might send three per day evenly spaced over a week, and number them. "This is test message 1.", "This is test message 2.", etc. Any of us noticing some missing can let you know. Sincerely, Gene Wirchenko

Am I right? Yes and no. I have tried over that time, but most of the time, I have had to work on other stuff. My own grid is a low priority until I have something useful working. I have tried to work with VFP's Grid control and kept running into trouble. [snip] Sincerely, Gene Wirchenko

VSS to git conversion
by Tracy Pearson 09 Jan '19

09 Jan '19

We are looking at changing things over from VSS to git. There are about 20 projects that we want to transfer the history of the files in to git. However, we do not want to transfer the binary files over. We haven't been using the FoxBin2PRG since we have been just working directly in the standard project manager in VFP. For example, a form in VSS is a binary file. It has had 16 changes to in over the past few years. We would like to have these historical changes stored in git allowing us to reference this history without the need to go back to VSS. The catch is, we only want to store the text equivalent of the form in git. Is there someone out there that has done this in the past? Thank you, Tracy

I wish. One of the things that Grid is supposedly not for is data entry. I need a grid that can handle that. Sincerely, Gene Wirchenko

The future of Xbase
by Johan Nel 09 Jan '19

09 Jan '19

Good day all, Not sure who of you are aware of it, but coming from a Clipper background I have been developing software since 1986 through Visual Objects, Vulcan.NET and now X# (XSharp). X# started out in 2015/16 as an open source compiler for Vulcan.NET and VO, based on Microsoft's Rosslyn open source project of the c# compiler. It integrates into Visual Studio and there is also an IDE 100% written in X# available. Good progress by the development team has already XBase++ and Harbour language packs available. The development team has decided to expose the development to a broader audience and a visit to the USA is planned in March. I apologize if this is maybe a bit off-topic, but VFP is high on the priority list of future languages to support and I felt you might maybe be interested in attending the presentation. I attach the details. Further information regarding the project can be found at http://www.xsharp.info Kind regards, Johan Nel Created: 04 January 2019 Introduction In March 2019 we are organizing our first US event, where we would like to meet our customers and potential customers from the United States, Mexico and other countries around the world. Since we are a small open source project and we have limited financial resources, we have chosen to organize this as a relatively low budget event. We have also chosen a location in the south of the US, so developers from Mexico and other Middle American countries are also able to come with a reasonable travel time. The main audience for this event is existing Visual Objects and Vulcan.NET developers. However developers working with other XBase languages, such as XBase++ and Harbour, are also invited, there will be enough interesting information for you as well. We will present the current state of the X# development and show how to migrate your apps from VO to .Net. We will also have time to explain some of the internals of the X# compiler and runtime and how you can use the new features in the product (generics, lambda expression, linq, scripting, multi threading etc) in your apps. We will also show you the support that we have for other dialects (such as XBase++ and Harbour). Our partner QLAdmin from Austin has helped us to set up an event that will be both informative but also attractive. You have the change to meet colleagues that create applications with the same tools, as well as enjoy presentations where we will demonstrate our new open source solution to help you move your applications forward towards .Net. There will also be some other interesting technical sessions as well. This summit is structured to encourage open and facilitated face-to-face discussion and idea sharing amongst all attendees. Refreshments will be provided all day with scheduled lunch and snack breaks. You are also invited to join in the group activities to continue your informal networking and make new friends in the X# world. Location The event will take place at the following hotel: Best Western Plus / Austin City Hotel 2200 South IH-35 Austin, Texas 78704 512-444-0561 https://austincityhotel.com/ • Near downtown Austin, with corner store nearby for snacks or forgotten items. • Complimentary hearty breakfast buffet is included in room charge. • Lounge features complimentary gourmet coffee machine, with drink/snack vending near meeting room. • Free onsite parking and Google Fiber wifi throughout hotel. • Hotel restaurant is open until 10pm, and the bar is open until 11pm. • Rooms equipped with king beds, work space, mini-fridge, microwave, Keurig coffeemaker. • 100% smoke free hotel environment. Agenda The preliminary agenda for the event is: Wednesday 5:00pm to 6:30pm Welcome Reception (see below) Thursday 9am to 4:30pm X# Summit 12pm to 1:15pm Group Lunch 6pm to 8pm Riverboat Dinner Cruise (see below) Friday 9am to 1pm X# Summit 1pm to 2:30pm Group Lunch Excursion (see below) Speakers At this moment the following speakers have confirmed: * Nikos Kokkalis (X# development team) * Robert van der Hulst (X# development team) * Rolf van der Hulst (Roboteam Twente) We are still looking for contributions. If you are interested in attending the event and presenting a session (or showcasing your own application) please contact us. Please note (as mentioned above) : we have a very small budget, so we can't pay for your travel or hotel expenses. Subjects The preliminary list of subjects is: * Migrating your Visual Objects applications to X# * X# Language improvements compared to Visual Objects and Vulcan.Net. * Understanding and making the most of X# and the X# runtime * .Net Core * Asynchronous programming and Multi Threading * XSharp Scripting and using Roslyn and the X# compiler from your app * Creating Services with .Net and X# * Application Show (show your application to other developers) * Using Artificial Intelligence in your application, with examples from the world of Robot Soccer * Question and Answers, and what do you expect from the X# project Registration To register for this event, please send an email to robert(a)xsharp.eu <mailto:robert@xsharp.eu>. The registration fee for the event is $ 350.

Most of them have no sense for other purpose than data entry. Yes, but I had a period of time where I was not using xBASE. That was about when the fancy browses had their day. I have looked at BROWSE, and it does not have quite what I want. > One of my first programming challenges was to do a component > exactly as you need it to (I'm talking about dBase III+ era), and > could do it, but the problem was that performed horribly, too slow > to navigate records and columns.

It is going to be fun, but I have some ideas. I am concerned with how the scrollbar works, but I may just come up with my own version that bypasses the issues. >Controlling every key for navigation and other needed purposes - >Controlling the visualization of each aspect of your info (think on >Autosizing columns, pre-programmed sizes, combination of both, >assuring that you show columns correctly and fluently ,etc) I do not plan to have every feature that Grid has, at least for the start.

I can not get proper row-level validation working consistently. I have tried and tried and tried. I keep finding cases where it breaks. I deal with a case, and something else breaks. It is very frustrating. I had quite a lot of trouble to get my test case to work. I had to experiment with events and methods, but once I got it, it worked and did so consistently. > And more importantly: Is really a grid what you need? why can't > you use an input form with navigation keys that scrolls data in background? Because some of the work that needs to be done needs multiple rows visible at once. [snip] Sincerely, Gene Wirchenko

Please >explain why you differ on opinion Because despite multiple efforts by me to get it to work, it would not work. I do not believe that Grid works. At the very least, it is so quirky, it is very difficult to use. Given that I have been able to learn how to use other VFP classes fairly easily, I lean to the view that Grid is buggy.

Custom Scrollbar
by Gene Wirchenko 06 Jan '19

06 Jan '19

Hello: I want to create my own grid. I am slowly making progress. I have decided that I need my own scrollbar control. It appears that a combination of Image controls will do what I need -- but do you have some other ideas? -- but I have not worked with VFP graphics. Now, I need to define some icons/images. What software do you recommend for creating these at the pixel level? I would like to be able to duplicate the appearance (colourwise) so I would like to be able to pick the colours off existing VFP controls (especially scrollbars) as well. One issue that I am concerned with is being able to have a scrollbar stretched and still look good. How does one stretch an Image properly? Is there anything you think I am not considering but should? Sincerely, Gene Wirchenko
