    This week we work also on the User Interface - the Flash GUI. It was challenging since neither me nor Loredana had previous experience in creating games under this application. Because of this fact, we searched for some advices on the net and after quite a long trial and errors we found something interesting here . Even that it didn't met all requirements, this tutorial was what we needed to get a quick start. The...

  • Processing NSDate into an ISO8601 string

      During the CSCW Lab, where I had the experience of working on iPhone, I had to connect to a XML RPC server. Some of the parameters of the request had to be formatted as ISO8601 standard. After some reading, I end up using the following code, managing both the conversion of a NSDate to NSString and a NSString to a NSDATE using the above format:   NSString –> NSDate -(NSString *)...

  • GPS – Global positioning system

    GPS is the oldest one from the frameworks available to the large audience. It isn't the first positioning system, but it is the one with the most success and longevity. It started as a military project in 1957. Because of the cold war, once the Russians sent to space the first man-made satellite, a team of scientists started monitoring its radio transmissions. The crucial discovery was that, because of the Doppler...

    While working on my new pet project, I encountered a situation in which I wanted to save some data to a file.

So find out that inside the gadget’s directory, you are free to create, delete, update files with no more rights required than the ...

Instead I looked at a white room with old furniture, a kitchenette with a grandma look - plastic was yellow instead of original color. The room is...

    Xcode – String concatenation

    Don’t be fooled that Objective-C is a Object oriented language. For decades operators overloading is something standard in almost all of them. But in Objective-C you don’t have it. Mostly, I believe that comes from the struggle of Apple guys to assure the stability of the system. A lot of errors can come from poorly designed overloads, thus the crashes can appear. Now let’s put some hands on...

While iterating in the structure using NSXMLParser, a event-based parser, I kept adding the pairs as name and values...

Create GUID in Visual Studio 2005

Dec 21st

Posted by Radu Poenaru in Others

2 comments

From time to time you need to create a GUID (Global Unique IDentifier) in order to mark your dlls. Looking in my Visual Studio 2005 I saw that this command wasn’t available in any tools menu, nor in the Customize toolbars one as a shortcut to a command.

After a quick digging on MSDN site I found this. It is written in Microsoft style – a lot of information, but no solution. It just mentioned something like ”hey, we have something that you want, but guess what – we don’t have it any more”:

  1. On the Tools menu, click Create GUID. The Create GUID tool More >
