Training day for MBS Filemaker Plugin

The people at are hosting a training for our MBS Filemaker Plugin. So if you want to spend a day with us learning about our plugin, please join us.

We make a guided tour and show you a couple of highlights and examples. Talk about what you can do and how you do some things. Later we will implement a couple of things in sample databases like the Audit function. Also download and upload with CURL is a good topic. We will look into the webviewer extensions and fill a sample form. Next we will do some image editing and writing a report into a Excel file.
Finally we have plenty of time for questions.

This event is in German (english event is also possible).
We meet 6th February 2014 at 9:30 am in Denkform office. Cost is 70 Euro (+VAT) and you can buy a 5 seat license for additional 70 Euro (+VAT).
You can register on the denkform website. After the event, there is the regular meeting which everyone can join for free and have dinner with us.

Other dates for similar events are: 8th May 2014, 7th August 2014 and 6th November 2014.

Tip of the day: Map Links on Mac and iOS

As described on Apple's website you can use special links to open Map app on Mac and iOS. For example here are two links:

So the URL always begins with and you add parameters. Like q for a simple search. You can use saddr and daddr to provide source and destination address for a route. You can include type of map with t parameter with "m" for map, "k" for satellite and "h" for hybrid.

Those URLs work fine on Mac desktop and iOS devices with FileMaker, Xojo and Real Studio.

Xojo Sale

As I just read there is a sale going on:

25% on renewals today
14% on new licenses with code GET14

And it seems like some people got an email about this sale.

Update: You don't receive the email if you opted-out for marketing emails. But you can opt-in again if you like to know about offers.

Tip of the day: avoiding cgi in the call to a web app

if your web app has an URL like this:

you can also have it like this:

For that to work, you need to modify the default .htaccess created by Xojo to look like this:
Options +ExecCGI +Indexes
DirectoryIndex webstarterkit.cgi
order allow,deny
deny from all
<Files *.cgi>
allow from all
<Files "">
allow from all
So we added the "+Indexes" and we added the line with "DirectoryIndex webstarterkit.cgi" with the name of our CGI. Next we added the allow to all for the Files with an empty name. This will make sure you don't get a forbidden message.

but after you installed our plug-in to /Library/QuickLook and you restarted the Finder or logged in the next time, your icons look like this:

Enjoy! This plug-in is freeware, so tell your friends. Version 1.4 adds support for upcoming 2014 Xojo versions.

SSL Trouble

Today I reported two bug cases for SSL connections.

Case 31707: Web Standalone leak
Yesterday I saw the blog article about using SSL in standalone web edition applications. Nice addition, but when I try it, it leaks a lot of memory. Over 10 MB per new session. Seems like some memory from the session/sockets are not freed. The bug does not happen in this magnitude without SSL.

Case 31706: SSLSocket leak with ServerSocket
When working the last days on a client server project for a client, I saw the problem that my sockets on the server are not freed. The management of the sockets is up to the server socket. But even as they are closed, the destructor is not called.
Digging into the reference counting system, I see that in connected event my SSLSocket object has a reference count of 5 while without SSL, it only has 3. So there is a leak somewhere in the handling of SSL Sockets.

Case 2820: Certificates with sslsocket, httpsecuresocket
This is an old case about a feature missing in Xojo. We can't check the certificate from the server in our SSL Socket. So we can't prevent a man-in-the-middle attack.
I'd love to change the plugin and add at least an event to provide the certificate data. This way code in the event could make decision and return true or false back to the socket on whether to accept of not.

We'll see what can be fixed for 2014r1.

Connecting to a Firebird database using Xojo, Real Studio or FileMaker

If you need to connect to Firebird, you can use our MBS SQL Plugin. First you need to set option on SQLConnectionMBS: The kOptionLibraryFirebird option must point to the name/path of the firebird library file, e.g. fbclient.dll. Next you connect to the database. Connection string for a local database is simply the file path like "C:\webfakt\daten\webfakt.fdb" in our sample. The username and passwords must be set, e.g. "SYSDBA" and "masterkey". Now call connect method and pass connection string, username, password and the client which is kFirebirdClient.

Now when you do queries, the plugin will ask firebird library to provide strings in unicode. For that the database must have a character set defined. But what happens if none is defined? In that case the try to convert the guessed character set to Unicode will destroy probably the umlauts in the text. The solution can be to cast the encoding like this: CAST(FIRMA as varchar(100) CHARACTER SET ISO8859_1)

So for each field we select, we redefine the datatype with a cast operation and fix the encoding. On the long run the database encoding should be defined to fix this and have the plugin automatically provide correct strings.

PS: Same works in FileMaker with our MBS FIleMaker Plugin and the SQL functions.

Tip of the day: Find network interfaces by name

We had this week the issue that we need to find a NetworkInterface object for a network interface based on the name. As NetworkInterface class does not have a property for that, we use our NetworkInterfaceMBS class to build a mapping from IP address to actual name. It works well here and I think this code maybe useful for you. Beside name, it also allows to use any IP or MAC address to specify the interface.

Function FindNetworkInterface(name as string) As NetworkInterface name = name.trim if name.len = 0 then Return nil // search by IP/MAC dim u as integer = System.NetworkInterfaceCount-1 for i as integer = 0 to u dim n as NetworkInterface = System.GetNetworkInterface(i) if n.IPAddress = name or n.MACAddress = name then Return n end if next // use MBS Plugin to build a mapping dim interfaces() as NetworkInterfaceMBS = NetworkInterfaceMBS.AllInterfaces dim map as new Dictionary for each n as NetworkInterfaceMBS in interfaces dim IPv4s() as string = n.IPv4s dim IPv6s() as string = n.IPv6s for each IPv4 as string in IPv4s map.Value(IPv4) = n.Name next for each IPv6 as string in IPv6s map.Value(IPv6) = n.Name next if n.MAC<>"" then map.Value(n.MAC) = n.Name end if next // now search interfaces by name, IPv4 or IPv6 for i as integer = 0 to u dim n as NetworkInterface = System.GetNetworkInterface(i) if map.Lookup(n.IPAddress, "") = name then Return n end if if map.Lookup(n.MACAddress, "") = name then Return n end if next End Function

xDev Magazine Issue 12.1

The January/February 2014 (12.1) issue of xDev Magazine is now available.
Here's a quick preview of what's inside:

* Birmingham 2013 * by Richard Duke
Did you miss the Xojo Conference in Birmingham, England last November? Don't worry--Richard's got the complete scoop, along with plenty of photos.

* Window Tricks * by Sam Rowlands
Mac OS can do a lot things automatically for you--if you know how to harness the right Cocoa calls. Sam shows how to get the OS to manage a window menu for you, save and restore window positions, add a document icon proxy, and much more.

* Reporting Valentina * by Paul Budd
Did you get a copy of Valentina Reports with last summer's OmegaBundle? You may have been wondering how to use the software, so Paul gives you step-by-step instructions on using it with Xojo.

* Smart Localization * by Trisha Duke
Localization might seem like something you add last-minute to your application, but it's really something you need to carefully plan. In this article, Trisha reveals her tips and techniques for localizing your Xojo applications.

Plus: Event-driven programming, tips and tricks, database structure, using AddHandler, RegEx, and much more!

Call delegate on main thread

We just added a new feature to the plugin: CallDelegateOnMainThreadMBS

We call the delegate on the main thread later with passing a parameter. Our plugin supports various combinations of up to 2 parameters of type string, variant, boolean, double, integer and object. If you need more combinations, please contact us.

Here are a few example calls:

CallDelegateOnMainThreadMBS AddressOf testString, "Hello"
CallDelegateOnMainThreadMBS AddressOf testNumbers, 5, 6
CallDelegateOnMainThreadMBS AddressOf TestNoParameters
CallDelegateOnMainThreadMBS AddressOf Test, "4th call", 4

This allows us to call methods to update GUI directly from a thread :-)
And with the automatic type matching, you can simply use addressOf/weakAddressOf with your method and if the plugin has a matching method, the compiler will accept and build the plugin.
PS: I added this myself because feedback case 16504 is not implemented.
