Big SQLite Cache for 64-bit in Xojo

Whenever you open a SQLite database in your application, please remember to first send this command via SQL Execute:

PRAGMA cache_size = 20000

this will increase the cache. Default is 2000 pages and with a page size of 1024 bytes that's only 2 MB of cache. You can easily set it to 20000 pages on modern computers for 20 MB. This way you increase SQLite performance a lot!

Now the best cache for SQLite is one where the whole database fits in. On the other side if you set cache bigger, it will only grow until the whole database is in memory. So for one of our projects here, we now use 2 GB cache limit for SQLite:

#if Target64Bit then
  db.SQLExecute "PRAGMA cache_size = 2000000" // 2 GB
  db.SQLExecute "PRAGMA cache_size = 20000" // 20 MB

If the database is 10 MB, of course the cache will only be 10 MB. But if the database is 50 MB for a table and this table is queried, it helps a lot of the whole table fits into the cache. And with 64-bit memory is available and you do not risk running out of it soon, so using it for the database cache is a good idea.

This works for SQLiteDatabase, iOSSQLiteDatabase, SQLDatabaseMBS and SQLConnectionMBS in Xojo as well as with our MBS Filemaker Plugin when used with SQLite.

FileMaker Pro, Server and Go in version 16.0.3

FileMaker Inc. just released a new version of their products:

See details for FileMaker Server 16.0.3, FileMaker Go 16.0.3 and FileMaker Pro 16.0.3.

Fixes include the problems with lost scripts when committing a record after a reconnect. And of course a couple more fixes.

The installation of the update is highly recommended to all users of FileMaker 16 to avoid the problem mentioned above!

Detect PrinterSetup data format

As you may know Xojo 2016r4 to 2017r2 made a move to use DirectDraw for printing. Xojo 2016r3 and older use DEVMODE structure to describe the printer setup in the ANSI version. Xojo 2016r4 and newer use the unicode version. You run into problems if you use an older SetupString with newer Xojo versions. Sadly Xojo missed to increment the version number in their string to ignore older setup strings automatically!

While the exact format of SetupString is not published, you can see it’s text with an embedded binary part. One of the values listed is DevModeStructureSizePS which shows the size of the binary data. Values are for example 1292 for older format and 1356 for newer format of the same printer. Please note the format can be printer specific and change depending on which fields are checked in the printer dialog!

In the byte stream you see first 32 characters in both versions, either unicode (64 bytes!) or ANSI text. Followed is the spec version &h0401 for Windows 2000 and newer. Next value is driver version. The following field is the size of the structure, not including any private, driver-specified data. This value can be &h00DC for size of DEVMODEW structure for Xojo 2017r2 and &h009C for size of DEVMODEA structure for Xojo 2016r3. The next number is the driver’s data size in bytes, e.g. &h0470 for my printer in both cases. If you sum it up, you get &h054C and &h50C, which are exactly the sizes above.

To detect the format of a setup string, you can do the following: You find the string DevModeStructurePS= in the setup string. If you don’t have it, this is an incomplete setup string, e.g. from a new PrinterSetup object and you can simply use it. But if you find it, you look in the binary data, if you find the bytes &h01 and &h04 exactly 32 or 64 bytes after the start of the binary data. Skipping two bytes the next two bytes should be &hDC &h00 for Xojo 2017r2 and &h9C &h00 for Xojo 2016r3.

Implementing the proper function to test a setup string is left as homework to the reader.

PS: If SetupString odes not start with "DoNotAlterThis=SetupString.2" or you are not on TargetWindows, you should not touch it as that may be a new future format.

PPS: The WindowsDeviceModeMBS class in MBS Win Plugin can help to convert from ANSI to Unicode and back if needed.

Arrived in Salzburg

Arrived in Salzburg for German FileMaker Konferenz:

See you all there!

Plugin Reorganization Summary

With last release we reorganized the Xojo plugins a little bit.

First, we renamed a few plugins

Plugin PartRenamed to

This makes it more clear that all those plugins are for Mac.

Second, we removed QuickTime and QTKit plugin parts, as Apple deprecated them years ago and Xojo dropped support for QuickTime long ago.

Third, we merged some plugin into others:

Plugin PartMoved to

This reduced the number of plugins a lot.

We moved few parts to new plugins, e.g. CoreAnimation and ImageKit classes. This way we reduced the dependencies between plugins.

In general the reorganization was well received and no class was missing even as we removed 5% of the plugin parts.

FileMaker Conference .fmp[x]Berlin 2018

We just got announcement for the FileMaker Conference .fmp[x]Berlin 2018.

This conference is organized by Egbert Friedrich and takes place from 7th to 9th June 2018 in Berlin, Germany.

As the conference is in english, this is your chance to meet people from around the world at a conference in Europe. And for a lot of people it's easier to get to Berlin than to cross the atlantic and deal with US immigration officers.

dotfmp is an effort of various leading European FileMaker Developers. It is meant to bring all kinds of higher level developers together to share knowledge, educate and challenge each other.
dotfmp starts at the 6th June 2018 in the later afternoon with a relaxed "Beer and Sausages" in one of the most famous Berlin Beergarden.The session days itself last from 7th until 9th June with various socialising events in the evenings. Additionally we offer support on 10th June to see more from Berlin and its surroundings.
dotfmp is a 3 Day-Unconference, Meetup, Hangout or Barcamp. It is an informal and self-organized effort to meet on a personal base.
dotfmp takes place in one of the most famous spots in Berlin. The GLS Campus is located in a vibrant area with a very short walking distance to all the famous restaurants.
We feel there are far too few possibilities to talk to, learn from, and hangout with fellow developers in a relaxed and informal environment. And we'd like to share work and get feedback from people chewing on similar challenges.

If you like to join the conference and present something, please register soon.

Xojo Forum now with 18000 members

The Xojo forum has been growing over the last years.

Since June 2013, the new forum is growing with content and it got huge.
The old Real Studio forum had 7542 members and 45738 topics and needed twelve years for that.

But the new Xojo forum got over double the members in a fraction of the time.
With now 18000 members and over 40000 conversations, it got the much more posts: 341349 postings vs. 265843. And only 9% are from Michel Bujardet, the current top poster.

Congratulations to the community for such a vital forum!

Click on a container to set points in FileMaker

Here is a nice example database to show how to make clicks on a PDF:

So first we render PDF to an image using DynaPDF functions. Than user can click on image inside a container to set a point. We draw the point with our GraphicsMagick functions in MBS Plugin and build a list of records for the points.

Later those points could be used to draw them on a new PDF with existing PDF in background.
Maybe this is useful for you? I'll include it with next plugins (or email me for a copy)

It’s Thanksgiving this weekend in Germany. Time to say thank you to all the good things that happen in live. Thanks for the wife and three healthy kids, thanks for having a great job and thanks to you my customers, who keep this company running.

Thanks for my father's colleagues who recommend him to buy a Mac 20 years ago. Thanks to Geoff for buying CrossBasic, making it REALbasic and thanks for Macwelt magazine to pointing me to it. Thanks for the first customers who hired me in 1999 to code for them, so I started a company in April 2000. Thanks to customers pushing me to learn C++ and writing plugins for Xojo and FileMaker. And thanks to everyone who bought a license. Over the years we can keep doing this, because people support us with their purchases. Thanks to keep me doing this instead of applying for a regular job somewhere to pay my bills.

And thanks for the travel around the world and the conferences. Organizing a conference is a lot of work, so thanks to all people who organize conferences. And of course thanks to everyone leaving their office to go to a conference. Only attending conferences makes them great and keeps them going!

So lets keep this running and see you at conferences in Salzburg, Madrid, London, Montreal, Denver, Munich and wherever another one will be!
