It may be a good idea to first check image on client before inserting it into a database. So the client would crash and not the server. As you see the server crashes when creating the thumbnails. (this is FileMaker Server 13. Newer ones may handle this better)

MBS FileMaker Plugin, version 6.4pr2

New in this prerelease of the 6.4 plugins:
  • Updated to DynaPDF
  • Added EmailParser.ReceiveDate and renamed EmailParser.Date to EmailParser.SentDate.
  • Added PHP.GetResultContainer function.
  • The dialog functions now set the dialog title on Mac, too.
  • Added LDAP.AddList and added more parameters for LDAP.Add.

FileMaker Conference Discount Offer

Just a reminder to all the people who visited out booth:
If you like to use the coupon code, please do it this month. The coupon code will expire soon. Alternative please email me what you need and I can setup an invoice for you.

In general we appreciate developers joining a conference. It is a big investment in time and money to actually attend in person and we want to honor this by offering discounts on our products. If I remember correctly all the offers in the exhibition area, you could actually save more money buying things on the show than the conference ticket costed you.

As FileMaker Inc. didn't provide a barcode scanner and barcodes on the badges, we have no email list to send a reminder.

DynaPDF Optimize Command

With the next prerelease of our FileMaker, Xojo and Real Studio plugins we will include DynaPDF and the Optimize command has two big changes: First, it now can now scale down images and reduce the size of PDF files significantly. Second, the license changes and the Optimize command is now included in the Pro license.

For optimize you can specify a few parameters. For each image in the PDF, DynaPDF will check the display resolution of the image. That is not the resolution stored in some metadata with the image, but the actual size the image will be displayed. You can specify the minimum resolution for images to be checked independently for Color, grayscale and 1 bit images. Next you define the resolution you want as maximum for the output images. For example you want to scale down all images with more than 100 dpi and reduce them to maximum 150 dpi. For the filter parameter you can specify the compression you want, e.g. JPEG. Converting images from Flate compression to JPEG with same or lower resolution will of course reduce the file size.

When optimizing PDFs, we can remove private data, invisible paths and create new link names. This further reduces size down and rebuilds the structure of the PDF. While doing the optimize we fix problems in PDF files automatically. Some PDFs which showed error messages when opening in Adobe Reader now open without errors.

Here an example:

The test PDF optimize-before.pdf is created with FileMaker 15 from the product catalog example with a few pictures. Than printed to PDF in FileMaker. Of course you can use whatever test PDFs you like for your own tests. Now we run through and let DynaPDF limit image resolution to 150 dpi. The new PDF optimize-after.pdf is much smaller. From 686 KB down to 89 KB (87% saved).

See yourself:
before vs. after

or when we scale them up at 200%:
before vs. after

We can extract the images and see that FileMaker placed a 816x612 Pixel big JPEG file (optimize-image-before.jpg) there. DynaPDF replaced that with a 206x154 Pixel big (optimize-image-after.jpg). I don't think you see the difference at the target size in the PDF. And 150 dpi is quite good for reading on screen and sending via email. FileMaker probably uses 600 dpi here to make sure it looks good when printing.

If you join FileMaker DevCon in Las Vegas, please visit our booth to try compression on your test PDFs!

MBS FileMaker Plugin 6.3 for OS X/Windows

Nickenich, Germany - (July 12th, 2016) -- MonkeyBread Software today is pleased to announce MBS FileMaker Plugin 6.3 for Mac OS X or Windows, the latest update to their product that is easily the most powerful plugin currently available for FileMaker Pro. As the leading database management solution for Windows, Mac, and the web, the FileMaker Pro Integrated Development Environment supports a plugin architecture that can easily extend the feature set of the application. MBS FileMaker Plugin 6.3 has been updated and now includes over 4000 different functions, and the versatile plugin has gained more new functions:

With the new version we add SSH functions. They allow you to connect to a remote server with Secure Shell protocol. You can authenticate via password or your private key. Than you can execute shell commands, provide input and receive output text. Our existing CURL functions provide SFTP file uploads and downloads using the same SSH connection parameters.

As the speak command in FileMaker is limited, we added a new Text.Speak command. Our speak command has less problems and also works on Windows. You can choose the voice and decide whether to wait for speech to finish.

For accessing smartcard readers, we got a set of new functions. You can list the readers, detect cards and transmit data to them. This is very low level and requires knowledge about the protocols used with your smart card.

Our menu creation is now much quicker due to optimized internal storage of menu items. The DefineQuickMenu function is now much quicker. And you can decide whether a menu item is selectable. This way you can prevent people from selecting a menuitem with a submenu attached.

We updated DynaPDF to version Our new functions DynaPDF.AppendImagePage and DynaPDF.AppendImagePages allow to easily add new pages for existing images, either from a container or a list of file paths. Our function to show difference between two pages can now be parameterized with a specific color tolerance.

For Webviewers on Mac you can now provide login credentials. When the website asks for a password, the plugin will supply it for you. This way you can visit websites without FileMaker showing a password dialog.

Our plugin can now create symbolic and hard links. When working with Word files, you can now replace images. For automated debugging you can now query the content of the data viewer window and store it in a log.

Finally we improved barcode reading, we accept now multiple file paths for Files.Delete and Files.RevealFile. GraphicsMagick handles resolutions better and allows querying/setting XMP data. PortMidi can now provide unicode device names.

See release notes for a complete list of changes.

FileMaker Magazin - MBS Artikel

Alternativer Wolf- und Bärenpark Schwarzwald

This week I had the chance to visit the Alternativer Wolf- und Bärenpark Schwarzwald. This is a project to protect wolves and bears here in Germany and they provides a home to eight bears and three wolves. Those bears are freed/rescued from circus and other places where they had a bad live with punishment. Now they can enjoy the rest of their lives in a natural environment there in the black forest. And visits can go and see them.
As those animals are used to humans they can't survive alone in nature.

My visit there was due to the FileMaker training organized by MKV. I gave a short presentation about the MBS FileMaker Plugin and had some time to talk with the trainees.

If you have a chance, please visit the two parks in Worbis and Bad Rippoldsau.

MBS FileMaker Plugin, version 6.3pr6

New in this prerelease of the 6.3 plugins:
  • Added SQL.FreeAllConnections.
  • Added WordFile.GetMediaFile, WordFile.MediaFiles and WordFile.SetMediaFile functions.
  • Fixed bug in DynaPDF.ShowDifference introduced in pr4.

When I have my next client visit to London, I may be able to schedule my trip to be there for a meeting.
Else you can meet me at DevCon in two weeks :-)

Tip of the day: Mount drive on FileMaker Server

From time to time we get the question whether we can copy files from FileMaker Server to a network share, e.g. for backup.

The answer: Yes, we can, but you need permissions.

When you login to a FileMaker Server and you mount a network drive, this drive is only accessible for the current user (your admin account). It is not available to other accounts on the server including the FMServer or SYSTEM account the FileMaker Server uses. That is a common problem for us here.
One solution is to mount the volume for all users on the local machine. And to provide permissions for anyone to write to a specific folder.

Another solution is maybe more elegant:
You can use Files.Mount to mount the shared folder yourself to a local drive letter. Than you copy files there and later you unmount it with Files.Unmount. This way you only mount when needed and you have full control over what credentials are used.
To copy files or folders you can simply use Files.CopyFile function.

MBS FileMaker Plugin, version 6.3pr5

New in this prerelease of the 6.3 plugins:
  • Improved CURL.GetResultAsContainer to detect extension based on mime type.
  • Fixed PortMidi.GetDeviceInfo's Name property to correctly handle special characters on Mac.
  • Added Clipboard.GetPicture and Clipboard.SetPicture.
  • Changed Barcode.Detect to better detect barcodes which have no whitespace around.
  • Added DynaPDF.AppendImagePage and DynaPDF.AppendImagePages.
  • Changed Files.Delete to accept a list of paths.
  • Added List.DeCombine function.
  • Added new flag to XML.Query to ignore namespaces and do the queries without them.
  • Fixed an issue where XML.Query would respond with two ?xml lines with encodings.

SQLite 3.13 with ICU

Recently a client asked for support of ICU in the MBS SQL plugin.
There is just a little problem. ICU libraries are 20 MB in size and including them for all platforms would increase SQL Plugin size for about 120 MB in size!
But you can use our SQL Plugin with an external SQLite library. Simply download the source code and built a copy with ICU enabled.

For your convenience I just built a copy of the SQLite library for Mac using the ICU library coming with OS X:


To check whether it is working, you can for example do a "SELECT upper('ä')" and see if you get back ä (non working) or Ä (working). You can try lower, like and regexp, too.
