Working with Edit Boxes in Visual FoxPro

I had a circumstance where I wanted to show a potentially large piece of text in a read-only edit box in VFP.

I was changing the height of the box to only show the actual content therefore if I only had one line, I wanted the edit box to only take up one line in height.

Sounds simple, right?

Not quite. My other requirement was that the user should be able to change the alignment of the text in the box. Left Align worked beautifully but whenever I switched the Alignment to Center or Right, the text disappeared.

What was going on?

When using alignments other than Left, Edit boxes have to be at least a certain height to display properly. What is the magic number? As it turns out, it's 34.

Try it yourself:

x = CREATEOBJECT("Form")
x.AddObject("editbox","editbox")
x.editbox.Visible =.t.
x.editbox.FontSize = 8
x.editbox.Value = "Here is my text"
x.Show
x.editbox.width = x.Width
x.editbox.ScrollBars = 0
x.editbox.BorderStyle = 0
x.editbox.Alignment = 2
x.editbox.height = 30 && Text disappears
x.editbox.height = 34 && Text Appears

Note: this is true in most versions of Visual FoxPro.

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.

Programmers vs. Developers vs. Architects

I received an email this morning from Brandon Savage 's newsletter. Brandon's a PHP guru (works at Mozilla) but his newsletter and books have some great overall perspectives for developers of all languages. However, this last one (What's the difference between developers and architects?) kind of rubs me the wrong way. Either that, or I've just missed the natural inflation of job descriptions. (maybe, it's like the change in terminology between Garbage man and Waste Engineer or Secretary and Office Administrator) So maybe it's just me - but I think there's still a big difference between Programmer, Developer and then of course, architect. The key thing here is that every role has a different perspective and every one of those perspectives has value. The original MSF create roles like Product Manager, Program Manager, Developer, Tester, etc - so every concept may pigeon hole people into different roles. But the statements Brandon makes are often distinction

FoxInCloud Stats

FoxInCloud sent this link a while back about their statistics regarding visits to their site: http://foxincloud.com/blog/2017/12/27/VFP-community-lessons-from-foxincloud-site.html What's interesting here is the breakdown of people. Yes, I think it's understandable that the Fox community is getting older. Another factor is the growth of the mobile and web environments taking over development. These environments really do push people towards the newer non-SQL or free SQL/hosted environments but more towards hosted storage options like Amazon and Google. A tool like FoxInCloud that helps MOVE existing applications to the cloud inherently competes with those environments. But FoxInCloud also allows developers to extend their application further by giving them a starting point using Javascript and the basic CSS (such as Bootstrap). If you're not rebuilding your application from scratch, it's certainly a great step forward. FoxPro VFP
