New Stuff Since Your Last Visit 1. Comment about Using BDE TTables to read or write text file records
BDE Ttables have helped me out with my work, as well. I owe it to these tables for the work I did on the pay for an essay project. That was one of the most difficult jobs of my life and this ttable made it easy for me.

Database Desktop on Windows 10
I've been using Database Desktop for years to maintain Paradox tables in a Delphi development environment, but it now appears that DBD doesn't work on Windows 10 for build 1703 or later.  Is there an updated DBD that does work?  Or is there an alternative tool I can use?  I've found several tools that will let me view and modify the data in Paradox tables, but none that will let me modify the table structures.  Any suggestions?  I don't have Paradox for Windows, only Delphi.

1. The Case for Delphi (On the Desktop)

In 1995 Borland revolutionized the world of software development when they introduced Delphi.

It had the distinction of being the first integrated development environment (IDE) featuring a fully object-oriented language and a blazing-fast compiler that produced highly optimized, native Intel machine code. Programs written in Delphi were among the fastest in existence – and still are.

After all these years, is Delphi still relevant?

You bet it is! (And, in many cases, it is still your best bet.)

Here's why...

2. Where Does Your Data Belong?

Back in the wild and wooly days of C/PM, DOS, and early versions of Windows, we programmers could store our data pretty much anywhere. It might not have been a good idea, but we could get away with it.

Things have changed drastically!!

If your program stores data, you need to know where it belongs, and that varies quite a bit from one version of Windows to others.

Read on to find out where your data belongs.

3. TDBGrid: Rerarranging Columns at Will

Delphi's TDBGrid is an incredibly useful component; one you'd expect to find in any professional development tool.

One of it's handy behaviors is that users can click in column headers and drag to rearrange column ordering to their liking.

Unfortunately, TDBGrid doesn't offer the developer any really easy way to rearrange grid columns from code. This is inconvenient because you might offer the user a choice of various columns upon which they can search, and it would be nice to make their chosen column the leftmost - at least. Often it makes sense to rearrange other columns as well.

This little class allows you to do that.

It has no exposed methods, and only two properties, so it's incredibly easy to use.

Read on to learn how it works and to get the code.

4. Grid, Column Order List

Delphi's TDBGrid is an incredibly useful component; one you'd expect to find in any professional development tool.

One of it's handy behaviors is that users can click in column headers and drag to rearrange column ordering to their liking.

Unfortunately, TDBGrid doesn't offer the developer any really convenient way to rearrange grid columns from code. This is inconvenient because you might offer the user a choice of various columns upon which they can search and it would be nice to make their chosen column the leftmost - at least. Often it makes sense to rearrange other columns as well.

This little class allows you to do that.

It has no exposed methods, and only two properties, so it's incredibly easy to use. Here are the steps:

1: Set up your TDBGrid. It must already be populated with the desired column specifications before using this little grid manager. Let's say it's named DBGrid1.

2: Instantiate an instance of TDBGridColumnManager:

  MyGridManager := TDBGridColumnManager.Create;

3: Specify the grid that TDBGridColumnManager jis intended to manage.

MyGridManager.Grid := DBGrid1;

4: From then on, you can rearrange the grids columns any time by simply setting the other property, ColumnOrderList, a string. When you do, the columns are reordered instantly.

ColumnOrderList should be a string of data column names separated by commas. Note that I said data column names, not header title captions; In a TDBGrid, these are the names assigned to the FieldName property of each column.

How it works:
