Posted by Raffael on Posted in Downloads, Test, Wordpress

WordPress2Doc - 1.2.8.5 ReleaseRound about 8 months ago, I release the last WordPress2Doc update. Some may have thought that the project has fallen asleep. But that is not the case.
There is always something going on/changing on the codebase (available on GitHub) and today there is also a new “real” release.
From now on WordPress2Doc is available in version 1.2.8.5. In addition to a new feature, the release also includes a bugfix (that fixes a problem with images coming from blogs with SSL / https support). So let’s do it quick today …

Default field lengths for address fields in databases

Posted by Raffael on Posted in Programming, SQL, Test, Wiki Tagged , , , ,

Standard lengths for address fields in databasesToday, we will dive into some more theoretical stuff. The topic of this article will be field lengths of database fields for addresses. For every second database I create, I am faced with the same problem: How long / “big” do I actually make the database fields for addresses? So fields, such as first name, surname, street, e-mail address, etc.
So far I have oriented myself to given requirements or old databases. But now I wanted to work up the topic once for all right. So the question is: Is there actually a standard for address field lengths?
Looking for standards for address field lengths
A search for “address field lengths for databases” spits a huge amount of hits. Unfortunately there are only opinions […]

Change Logitech FN-key behaviour without software

Posted by Raffael on Posted in Linux, Test, Tutorials, Windows

Change standard FN-key behaviourToday there is once again a short tip – this time for all owners of Logitech keyboards with a FN-key. Some time ago I was looking for a new keyboard. Criterion: Parallel usage of several devices – usually via Bluetooth. In the end the choice fell on the Logitech K375s. Stylish design, support for up to 3 devices that can be connected via Bluetooth or Logitech Unifying receiver. Only one small problem remained: the FN key.
No products found.
By pressing the FN key, the second assignment of individual keys can be activated. For example: You can control the volume by pressing the F12 key while holding down the FN key. So that’s the way I would prefer it at least. In practice, the FN key […]

How to generate Swiss QR Code in C# and VBA

Posted by Raffael on Posted in C#.Net, Programming, Test, VBA Tagged , , ,

Swiss QR Code in C-Sharp and VBAToday, we are looking into the field of business computer science. Since end of April, SIX has released the specification for the new Swiss QR Code according to ISO 20022. The Swiss QR Code is an integral part of the new Swiss deposit slip, the so-called QR invoice, which shall be implemented by all companies by mid-2018 at the latest. The Swiss QR code is placed in the so-called “number part with QR code” of the QR invoice.
In the following, we will discuss how the Swiss QR code can be generated using C # or VBA. To do this, we use the free QRCoder library, which I developed almost 4 years ago and to which recently added the Swiss QR Code. One more […]

.NET Core – gdiplus.dll not found in Linux

Posted by Raffael on Posted in C#.Net, Kubuntu, Linux, Linux Mint, Programming, Test, Ubuntu Server

A few days ago there was an issue raised in my QrCoder project. It was reported that the code would not run under Linux, as the following error message would occur:

Unhandled Exception: System.TypeInitializationException: The type initializer for ‘System.Drawing.KnownColors’ threw an exception.
—> System.TypeInitializationException: The type initializer for ‘System.Drawing.GDIPlus’ threw an exception.
—> System.DllNotFoundException: Unable to load DLL ‘gdiplus.dll’: The specified module could not be found.
(Exception from HRESULT: 0x8007007E)
at System.Drawing.GDIPlus.GdiplusStartup(UInt64& token, GdiplusStartupInput& input,

However the error message had its origin not in my QrCoder, but in the interplay of the .NET core framework with the GDI Plus library. The .NET Core Framework tries to access “gdiplus.dll” when accessing “System.Drawing.GDIPlus”, which is simply not available on Linux.
First solution approach
First, ensure that GDI+ is installed at all. This can be done with the following shell command:

sudo apt-get install libgdiplus

If libgdiplus is installed, however, another important step is missing …
Link libgdiplus for .NET Core
Because the […]
