What: We are developing a tool to track variables and their values in C programs as they change at runtime. Because of the low-level, unrestricted memory access the language allows, the challenge lies in collecting accurate information without disrupting the program’s execution. Our approach combines techniques from profiling with memory tracking to analyze dynamic allocation throughout the lifetime of a program.

Business Portal extends Microsoft Dynamics™ GP, providing a browser interface to securely access back office data over an intranet or an extranet. This distributed computing model brings significant security challenges, with levels of integration between clients, servers, and services. This model requires that security be an integral part of every implementation.

Memory protection
Buffer overrun attacks are among the most common mechanisms, or vectors, for intrusion into computers. In this type of exploit, the attacker sends a long string to an input stream or control – longer than the memory buffer allocated to hold it. The long string injects code into the system, which is executed, launching a virus or worm.

In AutoCAD® 2006 software, you can now create blocks that are intelligent and flexible. This exciting new feature, called Dynamic Blocks, enables you to modify blocks within specific constraints. A block library might have dozens of windows (if architectural) or bolts (if mechanical). With Dynamic Blocks, you can create one block that takes the place of all these related blocks and be confident that modifications match the dimensions of their real-world objects. As a result, the process of finding the right block is much more efficient. Inserting and editing the block is practically error-free.

Reflective programming is becoming popular due to the increasing set of dynamic services provided by execution environments like JVM and CLR. With custom attributes Microsoft introduced an extensible model of reflection for CLR: they can be used as additional decorations on element declarations. The same notion has been introduced in Java 1.5. The annotation model, both in Java and in C#, limits annotations to classes and class members. In this paper we describe C# a, an extension of the C# programming language, that allows programmers to annotate statements and code blocks and retrieve these annotations at run-time. We show how this extension can be reduced to the existing model. A set of operations on annotated code blocks to retrieve annotations and manipulate bytecode is introduced. We also discuss how to use C# to annotate programs giving hints on how to parallelize a sequential method and how it can be implemented by means of the abstractions provided by the run-time of the language. Finally, we show how our model for custom attributes has been realized.
