Check your compiler warnings and hints. They may still be errors.
I try to follow a zero hints and warnings policy for my code. (I admit I don’t always succeed though. 😉 ) But I was initially confused on how to solve this, and because of that learned something about not always following directions blindly… See this example code. This function should return true if everything […]

ReSharper Postfix Templates plugin
Developers: ever notice how you often, when typing some piece of code, most often a variable or other class reference, have to track back your keystrokes to surround it or prefix it with something else? The Postfix Templates extension for ReSharper by Alexander Shvedov (@ControlFlow) minimizes the times you have to backtrack what you typed, […]

Keeping Java updated without installing the Ask toolbar
Not only does the Oracle Java installer for Windows come with a useless toolbar from Ask, it is not enough to uncheck it at installation time. With every Java update you get, which you are recommended to install, you will be ‘ask’ed again and it is checked by default. I can count on myself to […]

An underrated operator: using EXCEPT in MS SQL Server to track changes
Working with a colleague who is a longtime Oracle user, I noticed he used an operator I didn’t know of, to grab hold of the differences in rows between two nearly identical tables: he used a “minus”. I couldn’t imagine MS SQL Server would not have something like it and it didn’t, it came up […]

Free up space on your OS disk by moving the Delphi XE6 installer files elsewhere
I noticed the free space on my SSD was getting smaller. Searching for ways to clean up a bit I discovered a ± 10 Gb hidden folder under c:\users\(account)\appdata\local\(guid). Inspecting its contents, it turned out to belong to the RAD Studio XE6 installer. No need to delete them, but I didn’t want them to take […]

Solving I/O Error 103 in LoadXMLDocument
In a Delphi console application that reads its configuration from an XML file, I unexpectedly ran into “I/O error 103”. I/O error 103 will look familiar to most of you Delphi developers, it means “File not open”. I traced it to this source line: xmlcfg := LoadXMLDocument(FConfigFilePath); LoadXMLDocument comes from the Delphi unit XMLDoc.pas, so […]

Registry setting may block nVidia driver updates
Not completely development related, this post, but since I am developing on a dual full hd monitor display setup, I like to keep my (nvidia) graphics card drivers up to date. I was unable however to update to the latest drivers, installation would say “failed” everytime.

VS2013 installation breaks SQL Server Data Tools in VS2010
After installation of Visual Studio 2013, an existing SQL server data tools project in VS2010 on the same machine would no longer build. The exception in the error window read “The “SqlBuildTask” task failed unexpectedly. System.MissingMethodException: Method not found: ‘Void Microsoft.Data.Tools.Schema.SchemaModel.DataSchemaModel.Serialize” (…) Fortunately, the solution was rather simple. It turns out there is a new […]

Downloading UTF-8 filenames from an FTP-server that does not support them, with System.Net.FtpWebRequest
I have written a windows service in .Net that monitors an FTP location for new files, which it then downloads to a local folder for processing. To be precise, the tool first renames the file before downloading it. It uses the .Net standard FtpWebRequest class from System.Net. Every once in a while, a file could […]
