GetShellWindow vs. GetDesktopWindow
18 June 11 09:06 PM | pavely | with no comments

In his post about running a process as a standard user from an elevated process, Aaron Margosis uses a technique that gets the access token of the shell process (typically explorer.exe) and uses that token to launch the new process ( Sasha Goldshtein also blogged about that). The first thing his code does is try to locate the shell process id. One way is to look for “explorer.exe” in the list of processes, but that’s a bit limiting, as there may be a different shell, or it may have been renamed for...

C++ 0x, Will you save C++?
05 February 11 08:20 PM | pavely | 13 comment(s)

The emerging new standard of C++ (dubbed C++0X, where X was supposed to be a decimal digit, but now can be considered a hexadecimal digit) will probably be finalized and approved this year (probably to become “C++11”), and is supposed to march C++ into a new era of productivity. Will that actually happen? In recent years, I saw declining usage of C++ in “regular”, data driven applications, UI and graphic applications, in lie of other environments, namely .NET and Java. As I do a lot of training,...

The recently released Visual Studio 2010 SP1 Beta brings many enhancements and bug fixes found since the product’s launch, most of them in the managed world. However, there are new enhancements to the good(?) old MFC , namely wrapping of some of the Direct2D interfaces. Direct2D is a new layer in the DirectX world, sitting on top of Direct3D, providing high performance and flexible 2D graphics. It was introduced with Windows 7 and Windows 2008 R2, but it’s also possible to install it on Windows Vista...

64 bit process addresses
12 April 09 09:00 PM | pavely | 11 comment(s)

native 64 bit processes get a huge address space of 8 TB (instead of the usual 2GB of 32 bit processes). However, to actually get this address space range, the executable image must be linked with the LARGEADDRESSAWARE flag. If it's not, only the lower 2GB will be available. Why is that? Why doesn't a native 64 bit process get automatically the larger address space? I'll leave you to think about this a bit - I'll answer in a few paragraphs. Here's a simple test program: int _tmain...
