MBS Xojo Developer Conference

Monday 31 March 2014 at 12:31 am
If you liked the Xojo Conference in Las Vegas, maybe you are looking forward to also visit our conference in Germany?

Hotel in Koblenz is reserved for 17th to 20th September 2014.

17th - training in German
18th and 19th - conference in English
20th - training in English

Registration is open and we are looking for speakers. If you are interested in coming, you can already email me to put you on the list.

And after the conference you can take train to Munich for the start of the Oktoberfest. ICE from Koblenz brings you saturday morning in just 5 hours to Munich where you can enjoy the great opening at noon. Due to size of festival I would recommend getting a hotel 100 miles outside of Munich and take the trains in and out.

Here a few pictures from the conference:

You probably read Bob's report, but I can add that new compiler is scheduled for Q1/2015. So when that means we have a beta in Q1, maybe a good working one in Q2?

For iOS, well, they target to get it out in Summer for alpha/beta. But this first version will probably not support plugins, e.g. linking in static libraries and calling them with declares. I have no problem providing a library for Xojo iOS with wrapper classes in Xojo which declare to the functions in a static library to get DynaPDF, SQL and ChartDirector to the iPhone/iPad. But we'll see how soon that's possible.

My Session at the Xojo Conference

Friday 28 March 2014 at 05:12 am
My session was moved to just after the lunch, so if you plan to come, please check the updated schedule tomorrow.

Tip of the day: Change EXIF metadata

Wednesday 26 March 2014 at 1:33 pm
Our XMP plugin can read/write EXIF metadata, IPTC and of course the XMP values:

dim file as FolderItem = SpecialFolder.Desktop.Child("test.jpg") // use XMPFilesMBS to open file dim flags as integer = XMPFilesMBS.kOpenForUpdate dim xf as new XMPFilesMBS(file, XMPFilesMBS.kUnknownFile, flags) // now read the metadata dim xmp as new XMPMetaMBS dim PacketInfo as XMPPacketInfoMBS dim xmppacket as string if xf.GetXMP(xmp, xmppacket, PacketInfo) then // set a value like here a different GPS altitude xmp.SetProperty xmp.kNS_EXIF, "GPSAltitude", "24695/43" // update file if xf.CanPutXMP(xmp) then xf.PutXMP(xmp) xf.CloseFile(XMPFilesMBS.kUpdateSafely) else MsgBox "Can't update." end if end if

Sneak Peak

Tuesday 25 March 2014 at 10:41 pm
The conference room is located on second floor and today staff was putting in tables and chairs.

See you there tomorrow!

Registration starts today at 7pm in main foyer (also tomorrow 7am there).

Tonight you can come to The Pub (there is only one pub in Monte Carlo) and try one of over hundred different beer types.

Just added: Zoom for HTMLViewer/Webviewer on Windows

Saturday 22 March 2014 at 10:21 pm
Today I found a trick to do the zooming on HTMLViewer in Xojo and Webviewer in FileMaker for Windows:

So we have now functions for both Mac and Windows.

Tip of the day: Use Int64 for file and memory sizes

Friday 21 March 2014 at 9:13 pm
While improving old projects, we often run into the case where we use integers for file sizes or memory calculations. That is normally no problem, but integers are 32 bit currently and like to overflow. So if you show a list of files with file sizes and you use integers, all files with 3 GB will show as -1 GB. Our old code was from a time where folderitem.length was an integer and no 64bit data types existed in Realbasic.

So better use Int64 for file sizes. Also use 64bit integers for memory allocations. Some versions ago the runtime.MemoryUsed property was updated to be UInt64 (in spring 2011). This allows now showing correct values for apps use more than 2 GB of memory. Remember the address space for Xojo apps is currently always 4 GB. Minus app, stack, system libraries, you have on Mac about 3.5 GB to work with.

MBS Xojo Developer Conference - Save the date

Thursday 20 March 2014 at 11:18 am
You can mark in your calendar the dates 18th and 19th September for the conference.

Location will be again the Contel Hotel in Koblenz. We ordered an extra Internet connection with WLAN for the conference. So we'll have two WLANs, the normal hotel one and our extra one. I hope this makes Internet more usable. The hotel also got an english version of the website.

Training days will be 17th and 20th, one in German and one in English.

Interested to do a presentation? Please contact us.

MonkeyBread Software Releases the MBS Xojo / Real Studio plug-ins in version 14.1

Tuesday 18 March 2014 at 2:43 pm
NICKENICH, Germany (March 18th, 2014) -- Monkeybread Software releases
version 14.1 of the MBS plug-in for Xojo and Real Studio.

The MBS plug-in comprises a collection of several plug-in parts which extend the Real Studio development environment with 2,000 classes featuring over 51,000 documented functions. Our plugins support all three platforms Mac OS X, Windows and Linux with all project types desktop, web and console.

Some of the highlights on the 14.1 update:

For Mac OS X we added MapKit classes using the open source MapKit framework. While Apple offers a MapKit framework directly, it's only available for 64bit application. The MapKit framework we use here is available for 32bit and 64bit and uses google maps internally. We can later update the plugin to either use Google or Apple map service once Xojo builds 64bit applications.

To list processes with details on Linux we added a LinuxProcessMBS class. It can show you which processes are running and query the list of open files.

In order to support proxies better for network connections, we added new classes: For Mac we have a CFProxyMBS class and for Windows a WinHTTPClientMBS class. Both allow to query current system proxy settings and help with detecting the auto config URLs and parsing the configuration scripts.

Our SQL Plugin got a couple of improvements. The SQLPreparedStatementMBS class has been rewritten with new methods to bind parameters by name. You can now decide to raise exceptions for errors in the SQLDatabaseMBS class. The SQLDateTimeMBS class is now working better with existing date objects.

We also updated barcode plugin with color properties for barcode generation, added more CoreImage functions and improved Cocoa file handle and printing functions. DynaPDF has been updated to version, LittleCMS to version 2.6.

See release notes for a complete list of changes.

Quiz of the day: What happened to this dialog?

Tuesday 18 March 2014 at 10:46 am

This is an open dialog in an app made with Real Studio, but the developer did make a mistake...
Please comment with your guesses. I'll give answer tomorrow. :-)

Answer: This is what you see if you call GetOpenFolderItem in a thread. The open dialog works only well on the main thread.

Survey Results

Monday 17 March 2014 at 10:45 am
We recently did make a survey about a possible Xojo Conference in 2014. From the survey we know that most people already visited a conference. 22% XDC, 50% MBS, 13% other and 35% none. As you see there are a few people who visited several conferences.

And from next question it looks like 90% could come to a conference. Still there are a few people saying no and we got a few xojo bashing comments in the comment section.

For the conference week, the majority doesn't care, but the week in favor by the others is the third one in September. If you like, you could go to Munich after conference and visit Oktoberfest (starting 20th September).

The location is interesting. We got 42% for Koblenz, 13% for Mainz, 28% for Frankfurt, 35% for Munich and 17% for the don't care choice. From comments we know that people love to have an airport next to hotel (like the conference in Atlanta years ago). But also people regularly ask for the bigger cities like Berlin, Paris or London. We'd of course appreciate if Xojo Inc. does a European XDC in fall in addition to an USA based in spring. And than they could go to the bigger places.

Training is also welcome for half of the people. And everyone loves social events, so we'll look into something new. The castle last year was a lot of fun for the attendees. We already got some people to speak there, but no sponsor. So the only sponsor probably will be again MBS paying the deficit.

When considering the location for the new conference, we had a lot of ideas for why to go there or there. A lot of people like to have a big city like Munich, but it's the most expensive option for us. Hotel prices in Munich are even higher than those in Frankfurt for nice hotels near center. Part of the reason the Xojo Developer conference costs what it costs ($750-$950) is that Xojo, Inc. flies in their staff which of course is calculated into the price tag. For us a remote conference like in Frankfurt or Munich would probably cost 2000 Euro more than doing it around the corner here. And that would lead to a higher price per participant of course. So doing it in Koblenz again we can keep prices down and charge the same price as last year (299 Euro). Again we offer early bird price of 249 Euro and speaker price of 149 Euro.

So we are looking forward to Koblenz in September, but final decision depends on the hotel options we have. We'll check that soon.

MBS Xojo / Real Studio Plugins, version 14.1pr5

Saturday 15 March 2014 at 10:26 am

Download: macsw.de/plugin/Prerelease. Or ask us to be added to our shared Dropbox folder.

Using Dropbox for plugins

Thursday 13 March 2014 at 5:38 pm
As I just added another user to my shared dropbox folder for our plugins, I'd like to ask if there are more users who want to be added?

I can add you to the shared folder for latest Xojo / Real Studio Plugins or to the shared folder for latest Filemaker plugin.

Interested? Just send me an email or chat message with the email address you use on Dropbox.com.
And if you don't use dropbox, I can of course invite you.

Xojo Cloud

Wednesday 12 March 2014 at 11:03 pm
The new Xojo cloud is a nice addition for quickly deploying a web solution for a client. From just a test installation to a full running solution. Of course you may need to upgrade from the smallest plan to a bigger one.

The package is designed to make it very convenient for the developer to run a web app. While you can get a small virtual private server for just $15 from Amazon, but with the xojo cloud you don't need to do a lot of things yourself:
  • Install and configure linux
  • install and configure web server
  • Install and configure a working backup
  • Install and configure an intruder detection software package
  • Install updates regularly
  • Configure web server to run perl cgi scripts
  • Configure firewall
  • Configure SSL certificates
  • Configure exceptions to Firewall to talk to a database server
With smallest package you get 512 MB of RAM, 20 GB hard disk, 20 GB of outgoing bandwidth, 20 Mbps network throughput and a single virtual CPU. Two bigger packages are available and if you need even more, you can ask. Probably all the configurations rackspace offers can be offered for xojo cloud.

512 MB is quite okay for a couple of web apps with limited use of memory. But the server is configured with 512 MB of virtual memory, so with swapping you have 1 GB total. As far as I see after launching first Xojo app there is about 135 MB free. You can see that in my little infos app. We have an AMD Opteron Processor 4170 HE, which run with 2.1 GHz. You can query memory and CPU statistics using our MBS Plugin functions.

If you want to add a database beside SQLite, you can rent a database server or use your own database server. But for a database server it may be worth renting one from rackspace and use the same data center (Chicago) to have a very fast local network connection to database. But for that you will have to ask Xojo to open the firewall for local connections.

What you don't get is SSH access or any kind of FTP. If you need, you have to build yourself one of the examples as a simple file manager. The control panel is still quite limited. I miss controls to see current CPU and memory usage of all the apps. Also missing for us are good default and error pages in case someone tries different URLs for our server.

For European users, well the cloud is not very usable. There are issues with uploads to cloud, both from the IDE for uploading the app and with WebFileUploader control. And as servers are only in the chicago data center, so a lot of web apps are not allowed to be hosted there for us in Europe. Privacy laws don't allow storage of data outside the European Union for us. And some data is not even allowed to be outside the own country. This will be changed once Xojo Cloud is supported for the London data center.

SQLPreparedStatementMBS improvements

Wednesday 12 March 2014 at 12:13 pm
You can now bind parameters by name with next plugin version:
// by index dim r as PreparedSQLStatement = db.Prepare("Insert into test_tbl(fid, fvarchar20) values(:1, :2)") r.BindType(0, SQLPreparedStatementMBS.kTypeLong) r.BindType(1, SQLPreparedStatementMBS.kTypeString) r.SQLExecute 12345, "Hello World by index" // by name dim sql as string = "Insert into test_tbl(fid, fvarchar20) values(:fid, :fvarchar20)" dim v as Variant = db.Prepare(sql) dim p as SQLPreparedStatementMBS = v p.BindType("fid", SQLPreparedStatementMBS.kTypeLong) p.BindType("fvarchar20", SQLPreparedStatementMBS.kTypeString) p.Bind("fid", 2345) p.Bind("fvarchar20", "Hello World by name") p.SQLExecute

More about Xojo 2014r1

Tuesday 11 March 2014 at 11:31 pm
So the new release is out and we all start using it. Of course a big project like Xojo is never done, but over a 100 bug fixes is a good thing. I personally like to see them work more on bug fixes than on new features, so the latest release has only a few additions.

The new AVFoundation based movieplayer control and the movie class can be used with our AVFoundation plugin. So you can actually use the plugin to access additional properties on the underlaying AVFoundation classes. For example you can use AVAssertMBS to get the metadata for the current playing movie like the lyrics or access the individual tracks of it.

The new IF function is really cool. It acts exactly like the normal IF command and only evaluates the one of the two choices for the result. This is more efficient than anything you can write yourself as a helper function.

In the web edition we got a major improvement for the listbox with header control. There is a new event HeaderPressed which allows us to do sorting in listbox on our own. And with HeaderStyle property we can style the headers differently.

If you just update projects to use 2014r1, be aware that a lot of quicktime classes have been removed. So Xojo is no longer using QuickTime at all (including Windows). MBS Plugin functions using QuickTime raise now in Xojo 2014 exceptions are the underlying plugin functions are no longer available. If you code sign your app, please update scripts to sign the framework instead of the dylib.

More to Xojo Cloud later.
