Teach me anout MFC extension DLL's and regular DLL's!

Posted By:      Posted Date: October 27, 2010    Points: 0   Category :.NET Framework


I have studied Wikipedia and MSDN, but still I haven't grasped the different DLL setups. I will put down what I think that I have found out so far. Please correct me where I',m wrong!

  1. A DLL can be of type MFC extension DLL or regular DLL.

  5. A DLL of type MFC extension may be complemented with a .lib-file that is used for statically linking. After statically linking the DLL, the caller can use functions in the DLL as if they where available during build time (all though it is possible to exchange the DLL for a new, compatible, DLL).
  6. A DLL of type regular may be complemented with a .a-file that is used for statically linking. After statically linking the DLL, the caller can use functions in the DLL as if they where available during build time (all though it is possible to exchange the DLL for a new, compatible, DLL).
  7. A regular DLL is compiled with a standard

The Decorator Pattern & Extension Methods

The decorator pattern provides a formal way to add new functionality to an existing type, without sub-classing. First question: What is wrong with classical inheritance? In and of itself, nothing is wrong with the good old Is-A relationship. It is very common to derive a new class from an existing base class in order to override a few virtual members, and add a pinch of new functionality.

The Decorator Pattern & Extension Methods

Numerous design patterns exist in the software world today, and ultimately nothing is preventing you from making your own (if people buy into it or not is another question). Furthermore, there is no 'master list' of patterns that all developers agree upon. While this is true, if you pick up any book on the subject, you will find a set of very common patterns most programmers agree are very useful. Many of these patterns were first formalized in the seminal book on the subject, Design Patterns: Elements of Reusable Object-Oriented Software (aka, the Gang of Four [GOF] book; not to be confused with the UK punk band of the same name).

Regular Expression to Match


Here is the kind of text I want to match via a regular Expression

The id="dgSchedule" is always present in the TAG but its location may differ

The table is span over multiple line/contains white spaces/tabs...

I have the regular expression to match the start and end tag respectively over a single line

\<table .*\>


The problem is to match the whole table span over multiple lines

<table cellspacing="0" rules="all" border="1" id="dgSchedule" style="border-style:None;height:100%;width:100%;border-collapse:collapse;">

		<td>From Place</td><td>To Place</td><td>Time</td><td>Bus Type</td>

	</tr><tr style="background-color:#DEECF5;">
	</tr><tr style="background-color:#EFF5FA;">
	</tr><tr style="background-color:#DEECF5;">
