Redefinition of ‘BOOKMARK’

If you include in a VC++ project <mapidefs.h> and <sqltypes.h> and build for the x64 platform you get a redefinition error.

1>C:\Program Files\Microsoft SDKs\Windows\v6.0A\include\sqltypes.h(283) : error C2371: ‘BOOKMARK’ : redefinition; different basic types 1> C:\Program Files\Microsoft SDKs\Windows\v6.0A\include\MAPIDefS.h(1142) : see declaration of ‘BOOKMARK’ The reason is that BOOKMARK is defined in both files.

C++ Renaissance at Microsoft

At the beginning of this year, Microsoft announced a “C++ renaissance”. Quoting from the description of a Channel 9 video with Craig Symonds and Mohsen Agsen: C++ is currently undergoing a renaissance. This means that, by definition, the language, compilers and compositional tooling are evolving and coalescing into a state that maximizes native developer efficiency,…

New Colors Game in WPF

Last year I posted a small MFC application on my blog, called Colors Game, about covering with a single color a grid initially colored in six colors. It wasn’t a big deal of an application, but it was fun and recently I decided to write a WPF version of that MFC game. This is the…

The Day Visual Studio Went Crazy

I said it before, the Visual Studio installer gets me mad. All is fine until you want to install the Service Pack. After that you cannot install additional components until you uninstall the SP. Because of that, you should make sure you installed the entire Visual Studio package before installing SP1. So I did, but…

Alchemy 2.0

The most reported bug for Alchemy so far has been the layout mess on small resolution systems, such as netbooks. It wasn’t a bug actually, but a feature. The application required a higher…

Generate Output from T4 at Build Time

Text templates (aka T4) is a great feature in Visual Studio, that proves helpful in many scenarios. I use it for instance in developing Alchemy. However, it has a significant drawback: it does not generate code automatically when you build your solution. To build the files and generate their output you have to manually run…

Finding Installed Applications with VC++

Finding applications installed on a machine (the ones that you see in Control Panel Add/Remove programs) could be a little bit tricky, because there isn’t a bulletproof API or method. Each of the available methods has its own weak points. WMI is slow and can actually be disabled on a machine. MSI API only shows…

Chrome 11 Speech Input

This Wednesday Google released version 11 of the Chrome Browser. One of the most important addition was the support for speech recognition for English. One can enable speech recognition in an input field by adding the x-webkit-speech proprietary attribute, like in this example:

The result should look like this (of course, in Chrome 11,…
