MBS FileMaker Plugin presentation from DevCon 2016

On the FileMaker DevCon 2016, I had a presentation of the MBS Plugin.
In case you missed it, you can now view the video:

MBS Plugin @ DevCon 2016

We recorded the screen on my Mac. So the sound is not very load, especially for people asking questions. But it's better than nothing and hopefully FileMaker Inc. will in future record vendor sessions, too.

You can also watch the German recording from FMK 2015.

See also video from DevCon 2017 and DevCon 2018.

Upcoming Changes for our SQL Plugin

From talks with clients, we got a few cool ideas for our SQL Plugin to make live easier or give you more flexibility.

We get some new method overloads for SQLValueMBS to pass MemoryBlocks for various blob field types there as value. So if you have a memoryblock and you pass it, the value is not first converted to a string (a copy of the bytes) and passed to the plugin. Now it passes the memoryblock directly. In general we want to have all plugin functions taking a block of bytes should accept either string or memoryblock to avoid extra conversions.

To quickly get the content of a blob field, you can now use asBLobMemory and asBLobString. Next the Prepare command on SQLDatabaseMBS now returns a SQLPreparedStatementMBS object, so you don't need to cast it anymore. For ODBC, we set the ODBCAddLongTextBufferSpace option now by default to false.

For SQLFieldMBS and SQLParamMBS we add ReadLongOrLob methods so you can read a blob value and have it be written directly to a file (folderitem) or to a stream. For the stream, you can pass any object of a class implementing the Writeable interface. So binary stream is fine as well as a socket, serial port or textoutputstream. This saves you may be a line of code, but it may help people looking for such a method.

For SQLValueMBS class, we added new methods to pass folderitem, memoryblock or Readable interface, e.g. a binarystream. So you can have the plugin stream from a file to a blob field for you from a file.

Next you can pass all parameters as a Dictionary to SQLCommandMBS. Also you can use a dictionary with Bind method in SQLPreparedStatementMBS, too. So if you have data for new record already in dictionaries, you can pass them to SQL commands. With SQLValueMBS you can now set it with a variant.

Now as we can set values for parameters by variant, we detect the type from the variant. So if the variant has a string, we set the parameter to be a string parameter. The auto detection works so well here, that now for prepared statement the binding of a type is optional. So if you bind values to a prepared statement with newer plugin without specifying the actual type, the bind will now work.

There is one thing to note: Passing a memoryblock or a string without a defined encoding, we take it as bytes (BLOB). If you pass text or a string with define encoding, we pass it as a text value. Please make sure you pass either explicit type or you make sure encoding is defined or not.

Tip of the day: DynaPDF form creation with calculation with FileMaker

And just after I wrote it for Xojo, we got a query to do the same in FileMaker. The following snippet creates four form fields. The last field is read only and has a calculation in javascript attached, so the PDF Viewer can calculate the sum of the three fields above. The example shows a second feature called number formats. The PDF Viewer can than format the number with the given number of digits, dot or comma as decimal or thousands separator and of course with a currency prefix/postfix.

 

Set Variable [$y; Value:50]

Set Variable [$script; Value:"var v1 = this.getField(\"Val1\");" & ¶ & "var v2 = this.getField(\"Val2\");" & ¶ & "var v3 = this.getField(\"Val3\");" & ¶ & "event.value = v1.value + v2.value + v3.value;"]

Set Variable [$script; Value:MBS( "Text.ReplaceNewline"; $script; 2)]

Set Variable [$a; Value:MBS( "DynaPDF.CreateJSAction"; $pdf; $script)]

#Create 1st field

Set Variable [$f; Value:MBS( "DynaPDF.CreateTextField"; $pdf; "Val1"; -1; 0; 0; 50; $y; 200; 20)]

Set Variable [$r; Value:MBS( "DynaPDF.SetTextFieldValue"; $pdf; $f; "50.00"; "50.00"; "Right")]

Set Variable [$r; Value:MBS( "DynaPDF.SetNumberFormat"; $pdf; $f; "NoneDot"; 2; "MinusBlack")]

#Create 2nd field

Set Variable [$y; Value:$y + 30]

Set Variable [$f; Value:MBS( "DynaPDF.CreateTextField"; $pdf; "Val2"; -1; 0; 0; 50; $y; 200; 20)]

Set Variable [$r; Value:MBS( "DynaPDF.SetTextFieldValue"; $pdf; $f; "100.00"; "100.00"; "Right")]

Set Variable [$r; Value:MBS( "DynaPDF.SetNumberFormat"; $pdf; $f; "NoneDot"; 2; "MinusBlack")]

#Create 3rd field

Set Variable [$y; Value:$y + 30]

Set Variable [$f; Value:MBS( "DynaPDF.CreateTextField"; $pdf; "Val3"; -1; 0; 0; 50; $y; 200; 20)]

Set Variable [$r; Value:MBS( "DynaPDF.SetTextFieldValue"; $pdf; $f; "200.00"; "200.00"; "Right")]

Set Variable [$r; Value:MBS( "DynaPDF.SetNumberFormat"; $pdf; $f; "NoneDot"; 2; "MinusBlack")]

#Create sum field

#This last field calculates sum of other fields

#Works only in PDF Viewers supporting JavaScript!

Set Variable [$y; Value:$y + 30]

Set Variable [$f; Value:MBS( "DynaPDF.CreateTextField"; $pdf; "Sum"; -1; 0; 10; 50; $y; 200; 20)]

Set Variable [$r; Value:MBS( "DynaPDF.SetFieldBorderWidth"; $pdf; $f; 0)]

Set Variable [$r; Value:MBS( "DynaPDF.SetTextFieldValue"; $pdf; $f; "350.00 €"; "350.00 €"; "Right")]

Set Variable [$r; Value:MBS( "DynaPDF.SetFieldFlags"; $pdf; $f; "ReadOnly"; 0)]

Set Variable [$r; Value:MBS( "DynaPDF.AddActionToObj"; $pdf; "Field"; "OnCalc"; $a; $f)]

Set Variable [$r; Value:MBS( "DynaPDF.SetNumberFormat"; $pdf; $f; "CommaDot"; 2; "MinusBlack"; " €"; 0)] 

PS: Needs newer plugin. EMail me if you need it today, else wait for the next prerelease.

Tip of the day: DynaPDF form creation with calculation

Today I wrote the following example code for a client. This snippet creates four form fields.

The PDF Viewer can than format the number with the given number of digits, dot or comma as decimal or thousands separator and of course with a currency prefix/postfix. PS: Technically we could also offer this for our FileMaker Plugin if needed.

Two months till German FileMaker Conference in Salzburg, Austria

Nur noch zwei Monate bis zur FileMaker Konferenz und zur MBS Plugin Schulung in Salzburg:



Vom 13. bis 15. Oktober 2016 treffen sich wieder ca. 200 Teilnehmer im Pitter in Salzburg.
Bitte bald anmelden um ein Ticket zu bekommen. Die Konferenztickets und die Zimmer im Hotel Crowne Plaza Salzburg waren in den vorherigen Jahren schon Wochen vor der Konferenz ausverkauft.

Dieses Jahr gibt es neben meinem MBS Vortrag auch einen zum iOS SDK. Mal sehen, was bis zur Konferenz noch alles kommt von FileMaker. Unsere iOS Extension könnte ein Thema sein.

MBS Plugin Schulung
Am Tag vor der Konferenz (12. Oktober) findet der MBS Plugin Workshop statt. Einen Tag mal Intensiv das MBS Plugin anschauen, durch die Beispiele gehen, einen Webservice implementieren und Funktionen ausprobieren. Limitierte Anzahl von Plätzen und gleiches Hotel wie Konferenz, also bald anmelden.
(Noch wenige Restplätze verfügbar.)

Show download in a new tab

In a Xojo Webapp you can not just provide files for download, you can also put them on links:

dim p as Picture = LogoMBS(500)
dim w as new WebPicture(p)

w.Filename = "image.png"
file = w

myLink.Target = myLink.kTargetNewWindow
myLink.URL = w.URL

myLink is a WebLink object on the web page. File is a WebLink property defined in the webpage.
The link now opens in a new browser window or a new tab. For a PDF or image file, this will show it directly in the browser and not start a new download.

Using NetVerify web service with FileMaker

Today we worked with a client using our plugin to implement the netverify API calls using our CURL functions.

As you see this service takes form data with a JSON text and an image file. The picture is a photo of the driver license and this API returns the actual data of the driver and validates the ID. So if the driver license is invalid or expired, you get back an error. People can use this in the field, take picture with iOS device and than perform a script on server to call our plugin to query the server. The result can than be used in the FileMaker solution.

#Setup transfer

Set Variable [$curl; Value:MBS("CURL.New")]

Set Variable [$result; Value:MBS("CURL.SetOptionURL"; $curl; "https://netverify.com/api/netverify/v2/fastfill")]

Set Variable [$result; Value:MBS("CURL.SetOptionVerbose"; $curl; 1)]

Set Variable [$result; Value:MBS("CURL.SetOptionUserName"; $curl; "05f1e486-3452-4265-3434-77d53bdc7fb9")]

Set Variable [$result; Value:MBS("CURL.SetOptionPassword"; $curl; "Krpo1QNoSokiChtghfkloFR9YdKFidLJ7")]

Set Variable [$result; Value:MBS("CURL.SetOptionHTTPHeader"; $curl; "Accept: application/json"; "Expect:")]

Set Variable [$metadata; Value:"{\"type\": \"DRIVING_LICENSE\",\"country\": \"USA\"}"]

Set Variable [$r; Value:MBS("CURL.FormAddKeyValue";$curl; "metadata"; $metadata)]

Set Variable [$r; Value:MBS("CURL.FormAddKeyContainerContentType";$curl; "backsideImage"; "test.jpg"; Test::Image; "image/jpeg")]

Set Variable [$r; Value:MBS("CURL.FormFinish";$curl)]

#Run transfer

Set Field [Donor Docs::ResultCodePost; MBS("CURL.Perform"; $curl)]

#Check result

Set Field [Donor Docs::DebugTextPost; MBS("String.ReplaceNewline"; MBS("CURL.GetDebugAsText"; $curl);1)]

Set Variable [$result; Value:MBS("String.ReplaceNewline"; MBS("CURL.GetResultAsText"; $curl);1)]

Set Field [Donor Docs::ResultTextPost; $result]

Maybe this script helps you if you need to talk to a similar service.

Recent changes for DynaPDF licenses

Did you notice recent changes to the licenses and features in DynaPDF?
There were two changes which may have gone unnoticed by licensees of the DynaPDF library:

1. Extracting images is now possible with Lite edition due to the new GetImageObj function. This does not apply to inline images, but to all of the big images and those are usually the ones of interest. e.g. if the PDF is from a scanner and only contains a big JPEG stream, you can get this image with Lite instead of Pro. The Pro version still offers more details with the parser interface where you can see which image is used on which page and with what output size. This allows you to know the display resolution, so you can detect low resolution images.

2. The optimize command moved recently from being part of the PDF/A add-on down to the Pro version. You still need the PDF/A add-on to convert arbitrary PDF files to PDF/A. But if you only need to reduce file size by removing duplicate content (e.g. common fonts or images in merge PDFs), you can now just go with your Pro license. This also applies to scaling down images to reduce file size even more!
The optimize command can be used to fix errors in PDFs as it rebuilds the content streams to make them error free. Especially when you archive emails from various clients, you may want to rebuild them just to make sure they display in the future on all readers.

If you are interested in a license, be sure to contact us with your wishes, so we can see if we can build a nice bundle for you for various licenses or apply any current discount offer.
All features are available for FileMaker, Xojo and Real Studio solutions.

Talking to a SmartCard in FileMaker Pro

We had today some progress on talking to a SmartCard on Windows from FileMaker. Below the script which connects to the card and runs a query to figure out the version of the card:

 

If [MBS( "SmartCard.Available" ) = 1]

#Start a new session

Set Variable [$SCContext; Value:MBS( "SmartCard.Init" )]

If [MBS( "SmartCard.Valid"; $SCContext )]

#Query list of readers and pick first

Set Variable [$SCReader; Value:GetValue ( MBS( "SmartCard.ListReaders"; $SCContext) ; 1 )]

If [MBS("IsError") = 0]

#Connect to card

Set Variable [$SCConnect; Value:MBS( "SmartCard.Connect"; $SCContext ; $SCReader ; "Shared"; "any")]

Set Variable [$PRotocol; Value:MBS( "SmartCard.GetActiveProtocol"; $SCContext)]

If [$SCConnect = "OK"]

#Run a query

Set Variable [$Result; Value:MBS( "SmartCard.Transmit"; $SCContext; "0200000008000000"; "00ca018202"; 512 )]

#Result is 4 bytes. Starts with C901 for Version 5.0 or C903 for Version 5.3

Show Custom Dialog ["Version"; $result]

#Disconnect

Set Variable [$SCDisconnect; Value:MBS( "SmartCard.Disconnect"; $SCContext; "Leave" )]

Else

Show Custom Dialog ["Error"; "No card available."]

End If

End If

#End Card Session

Set Variable [$SCRelease; Value:MBS( "SmartCard.Release" ; $SCContext )]

Else

Show Custom Dialog ["Error"; "Failed to initalize"]

End If

Else

Show Custom Dialog ["Error"; "No SmartCard API on this OS."]

End If
