QRCoder demo In modern times QR codes should be known by pretty much everyone.

As a fairly serious geek this should be reason enough to engage a bit more in detail with the technology behind it. And what way seems to be more suitable than implementing a QR code generator by yourself?
Because C# is my favourite programming language, the choice fell accordingly to this language. Sadly information on the QR code are not so easy to get. The easiest way of course would be the official way – simply buy the ISO/IEC document. That would be the ISO/IEC 18004. But there’s also a crux on that. The ISO 18004 costs round […]

Workaround: Canon EOS 300D Windows 7 drivers

Recently I put my hands on a Canon EOS 300D and should copy a few photos from the camera to the PC. Easier said than done. The camera has a few years under his belt and Windows 7 was seemingly not able to find suitable drivers. Also the Windows driver search did not help.
Now comes the part where I want to apologize for the misleading headline. In fact I have no Windows 7 driver for you. However, I have a solution on how to get the Canon EOS 300D running under Windows 7 without additional drivers. Therefore just a setting in the camera menu must be changed.
Connect Canon EOS 300D with Windows 7 – how it works
Step 1:
Turn on the camera and click on the “Menu” button on the left edge of the display.

I already wrote an article about how to embed Youtube videos in PowerPoint 2010 presentations. Today I want to show you how this works in PowerPoint 2007. However, for this you need first the developer tools. If you do not have this enabled, you can catch up quickly in this way.
I would like to mention quickly that the screenshots in this manual are from PowerPoint 2010, since I have no PowerPoint 2007 here. The method that I show here, but definitely works well with PowerPoint 2007. So please do not be put off by the screenshots.
Step 1:
Click on the Developer-Tab in the ribbon menu and then on the button with the hammer and wrench. A window opens with a fairly long list of controls, which can be embedded into your PowerPoint presentation. Select from this list the “Shockwave Flash Object” and confirm by clicking the “OK” button.

If the Microsoft Office applications come to their limits, you can help out in many cases with the developer tools. These allow you to write macros, which are small programs in VBA (Visual Basic for Applications) and thus still give your Office projects that certain “liveliness”. However, the tab with the developer tools (Developer tab) isn’t displayed by default. How to enable it in Office 2007 and Office 2010, I want to show you (using PowerPoint) today.

At the moment I have to do a lot off PowerPoint stuff, so there may come the one or other article concerning Microsofts PowerPoint in the next days. I will not go directly to the basics, but rather the one or other little trick that was (hopefully) not known by some of you .
