How to fix Windows XP Bluescreen Error 0x0000007B

Posted by Raffael on 01/21/201301/21/2013 Posted in Tutorials Tagged 0x0000007B, AHCI, Bluescreen, IDE, Windows XP

Meanwhile I’m going three tracks on my laptop. This means concretely – Windows 7, Windows XP and Linux Mint 12 are bid me welcome every time I boot my laptop.
After installing Windows XP, however, I was faced with a blue screen and the following error message at the first boot:
Stop: 0x0000007B
I was on the point of doing to install XP again, when I found a solution which is much more convenient. In the BIOS of my laptop the SATA AHCI mode was set. Switching to the IDE mode brought the desired success. XP simply isn’t delivered with an AHCI compliant driver.

In the last days I once again tinkered a bit. Certainly more bad than good, but where are no professional tools, there won’t be high quality. But the ultimately goal was not a professional product, but rather a simple and cheap solution. But what is it all about?
The product of my tinkering is a low-cost GSM door opener. That is simplified a small device, that opens your door when you call it and may bring the costs next to nothing. And now a little about the implementation …
Anyone who wants to get an overview about the project, can view the following video, which I made from the final product.

To build a similiar application you need the following components:

Nokia 6230i
12V relay (a 5V relay would be better, but I had none)
Connector strips
A few wires

First I disassembled the phone and removed the vibration motor. To the now vacant contacts on the phone board […]

How to solve representation/encoding errors in C# Winforms applications

I know the title of this post hurts, but I wasn’t able to describe the problem with fewer words. But let us get to the point. As part of the development of my cloud downloader I encountered (among much others) the following problem. Korean characters were displayed as blank boxes, even though they were shown in the source code editor correctly. Those of you, who wonder now, from where you can get the Korean characters on your keyboard, should just stop by Google Translate. (The screenshot below illustrates the problem once again. Please click to enlarge the image.)
Koreanische Zeichen falsche Darstellung
On the Internet I found only very few solutions. And almost all were, in my opinion, rather suboptimal. In most cases the following solution was proposed:
It is recommended that you call the SetCompatibleTextRenderingDefault() method with […]

At first there was Facebook. But now there’s Google Plus. And yeah, I like it. But what is a social network without contacts? Probably nothing. But who thinks, Facebook contacts can be easily transfered to Google, is on the wrong way.
For a short time there was this plugin for the Chrome browser, named Friend Exporter, which has taken over the job very well. However, this was quickly blocked by Facebook. But there is another way that I want to show you below.
How to export your Facebook friends and import them in Google Plus
The workaround to import the contacts works with the help of Yahoo mail. If you have no account there, then you can just create one here. It’s free and takes less than 2 minutes.
You have a Yahoo mail account? Then you can […]

How to save user input in C#

Posted by Raffael on 01/09/2013 Posted in C#.Net, Tutorials Tagged C#, how to save user input c#, how to save user settings c#

On request of a reader, I’ll show you today some C# basics. After I had posted a little snippet for dealing with the AppSettings, I was asked how we could now actually save user input on a GUI with help of this snippet. Here comes the solution.
For clarification, I have a created a little C# WinForms project in Visual Studio. The WinForm got a label and a textbox on it. Also the above mentioned functions for loading and storing values in the AppSettings will be used.
If you have created the project and added to the controls, your Application should look similar to the left-hand picture.
Next, you two need to add event handlers. The easiest way is via the “Events” window. (This is the one that […]
