Things to do in Denver beside XDC


As of now I am signed up for the XDC 2018 conference in next April. Hotel is reserved as reservation can be adjusted easily later when flights are booked. Now I am looking for things to do beside the conference. For example:
  • In Denver
    • 16th street, food walk area with lots of shops and restaurants
    • Capitol in Denver with the one mile high step.
    • Denver Zoo
    • Children's museum of Denver, if you come with family.
  • In the Rocky Mountains
    • Trail Ridge Road with 3713m high pass
    • Independence Pass with 3687m high
    • Loveland Pass with 3655m high
    • Frisco historic park, behind Loveland pass.
  • A trip to the north
    • Mount Rushmore National Memorial
    • Crazy Horse Memorial
    • Devils Tower National Monument
    • Scotts Bluff National Monument
  • West of Denver
    • Colorado Railroad museum
    • The Buffalo Bill Museum and Grave
    • Golden city with Golden History Museum and Clear Creek Historic Park Trail
    • Roxborough State Park
Anything else you can recommend or plan to visit?

If you come by airplane, you should know there is a train from airport, which brings you directly from the main building in the airport down to Union Station. It costs only $9 and you can walk to the conference hotel.

Updates for Updater, WebStarter and Bugreporter Kits


Today we update our Xojo developer Kits for Updater, Bugreporter and Web Starter. The main point is the move to use Xojo 2017 everywhere and remove the example projects for Real Studio. And over the years we collected a few improvements and bug fixes, which now go in the release for everyone.
  • Bug Reporter Kit 1.3
    • Added console example project.
    • Updated for Xojo 2017.
  • Web Starter Kit 1.2
    • Added helper functions for WebPopupMenu
    • Fixed some back buttons.
    • Added low level exception/signal handling classes from Bug Reporter Kit.
    • Changed code because some App.File* functions which are not available in newer Xojo versions.
    • Renamed Hash Function to not conflict with hash function in other Web components.
    • Updated for Xojo 2017.
  • Updater Kit 2.1
    • Fixed timeout property for CURL.
    • Updated for Xojo 2017.
Those updates are free for all current license holders. Of course if you have the code already in your projects, you may just look on our changes and maybe transfer them to your project.

Interest for UK Xojo event in November 2017?


It is still a lot of time till XDC in April. You probably all sign up till end of October to get the $200 discount on the XDC Ticket, right?

So how about a smaller local event in London again?

We could go back to the Antoinette Hotel in Wimbledon, which is located a bit outside of London, so more affordable, but still you can just take a train to center London easily from Wimbledon.

If interest is good, I'd love to organise an event:
  • Thursday an optional Xojo training day with me for beginner/intermediate level.
  • Thursday the great buffet dinner
  • Friday a conference day with a few presentations.
  • Friday evening dinner together
  • and you can stay the weekend and visit London!
Here is a survey to find interest:
surveymonkey.de/r/CBKZNVT

Please let me know if you are interested, so I can put all people on the list.

LibSndfile and TagLib plugins for Xojo


Over the weekend I added two new plugin parts which will come with next plugin release:

LibSndfile, an open source library to read and write sample data with various sound file formats.
We compiled it for all targets and it seems to work well so far. The website has a table for supported audio formats.
Our new SoundFileMBS class provides the generic interface and allows you to load the library, open or create files and read/write samples in various formats.

Due to being LGPL, you need to build yourself or get the libraries from us prebuilt. We can’t include GPL code in the plugin, but as it’s LGPL, you can load the library in your closed source app at runtime without problems.
Website: www.mega-nerd.com/libsndfile/

TagLib, an open source library to read metadata from audio files, e.g. ID3 tags.
Now we first add the generic interface which works for all file formats supported. See new classes like TagLibTagMBS.
Later we can add specific classes for individual formats based on demand.

This library is available both with LGPL and MPL. As we have to statically link the library (it’s C++), we need to use the Mozilla Public License, which doesn’t restrict us like the GPL does.
Website: taglib.org

Under the Radar Podcast


The last days I enjoyed listening to a couple of episodes of the Under the Radar podcast.

Originally pointed to by Paul Lefebvre's tweet, I quickly subscribed as they talk about various topics for independent app developers and those episodes are very interesting. They face similar issues as myself and so I like to hear their solutions.

Thanks to David Smith and Marco Arment for their apps and the podcast.

And thanks to Xojo Inc. for supporting the shows. Xojo is sponsor for episodes #92 and #93. Coupon code is RADAR.

Windows, Xojo and the Clipboard


You may know that we have a few clipboard dedicated classes in our Xojo plugins.
Now Xojo’s move to DirectDraw in 2016r4 and subsequent changes in 2017r1 and 2017r2, we had to adjust our plugins to keep working on Windows. So for next plugin version we include fixes to our SetPicture and GetPicture functions to correctly put a bitmap on the clipboard. Our plugin can get/set the bitmaps to the clipboard now in 32 and 64bit.

The clipboard can hold several data types and Windows defines a couple of standard formats. Beside the bitmap type, there is a DIB type for a device independent bitmap and Metafile Picture for vector graphics. Normally Windows should convert from DIB to BITMAP or back.

Still some applications like Excel or Word look for the DIB and the conversion from BITMAP doesn’t work well. So we added new SetDIB/GetDIB functions to put a Xojo picture on the clipboard in the DIB format. This should solve problems people may have with clipboard.

If you like to try the newer plugins, please do not hesitate to contact us.

Multiple recordsets with Microsoft SQL Server


If you try to run two SQL statements on one connection, you often see this error message:

"HY000 [Microsoft][SQL Server Native Client 11.0]Connection is busy with results for another command"

We regularly see the problem with Microsoft SQL Server, but it also happens with Sybase ASE and others.

To solve you can set the option "SQL_ATTR_CURSOR_TYPE" with the value "SQL_CURSOR_DYNAMIC" to get a server side cursor. This will tell the connection to use a dynamic cursor and you can have several of those.
In Xojo:

dim cmd as SQLCommandMBS
cmd.Option("SQL_ATTR_CURSOR_TYPE") = "SQL_CURSOR_DYNAMIC"

in FileMaker:

MBS( "SQL.SetCommandOption"; $Command; "SQL_ATTR_CURSOR_TYPE"; "SQL_CURSOR_DYNAMIC" )

For next plugins we will include code to make sure you can set the option on the connection and pass it down to all commands on that connection.

Alternatively you can use the flag MARS_Connection when connecting inside the connection string:

"bedlam-m\\sql2014en@test;MARS_Connection=yes"

This is global option for the connection.

Xojo 2017 Release 2

URL scheme handling in Xojo


Handling URL schemes in both Mac and Windows can be tricky.
For Mac you need to define plist entry to declare the URL scheme and later handle the AppleEvent.
For Windows it is more difficult. First you edit registry to declare your URL scheme. Than you need to handle the URL as start parameter. But as a second copy of your app may be launched, you need to talk yourself to the first instance via IPCSocket and pass URL command to main app.

Robert Beier from Dibomedia GmbH in Leipzig recently implemented a helper class to handle this and put it on githup:

github.com/CranberryStackCookie/xojo-url-scheme

Feel free to send feedback including bug fixes to him. And next time you meet him at a Xojo conference, you can of course invite him for a drink!
