COM dll, Regular dll, extenstion dll, win32 dll - differences?

Posted By:      Posted Date: December 04, 2010    Points: 0   Category :.NET Framework


I know this is pretty simple, but I have always used Add reference in Visual studio and added COM dlls which created an interop dll and i worked that way.

Suddenly, I came across a dll that is not a COM. Now I searched over the internet and got a couple of infomation which is not deep enough :(

1. COM dll

2. Regular dll

3. Extenstion dll

4. win32 dll

for the above four entities I would like to know

1 - the languages used to create them?

2 - diffrences between each of them?

3 - is this dll compatible with .net framework?


one more question, Can we consume a regular DLL (which is not a COM dll) in a dot net application without writing an explicit wrapper class (because for COM dll, Visual studio generated interop dll automatically)?

Sorry, if those are too many questions on a single topic, but I would regret any inconvenience.

Any replies appreciated. Thanks, Maran.

Inside Windows: An In-Depth Look into the Win32 Portable Executable File Format, Part 2


The Win32 Portable Executable File Format (PE) was designed to be a standard executable format for use on all versions of the operating systems on all supported processors. Since its introduction, the PE format has undergone incremental changes, and the introduction of 64-bit Windows has required a few more. Part 1 of this series presented an overview and covered RVAs, the data directory, and the headers. This month in Part 2 the various sections of the executable are explored. The discussion includes the exports section, export forwarding, binding, and delayloading. The debug directory, thread local storage, and the resources sections are also covered.

Inside Windows: An In-Depth Look into the Win32 Portable Executable File Format


A good understanding of the Portable Executable (PE) file format leads to a good understanding of the operating system. If you know what's in your DLLs and EXEs, you'll be a more knowledgeable programmer. This article, the first of a two-part series, looks at the changes to the PE format that have occurred over the last few years, along with an overview of the format itself. After this update, the author discusses how the PE format fits into applications written for .NET, PE file sections, RVAs, the DataDirectory, and the importing of functions. An appendix includes lists of the relevant image header structures and their descriptions.

Win32 Resources: Using C++ to Programmatically Retrieve a Global Cursor's Shape and ID


Getting global cursor information is useful when developing software that drives or gathers information about other UI-based applications, including information about a remote machine. This article describes a way to programmatically identify the current cursor's ID and bitmap at any point in time. The first technique described is based on polling for information and shows how to get the handle of the current global cursor. This handle will then allow you to get information about the cursor. You can also monitor WinEvents for changes to the global cursor.

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;">
	<tr class="blackbar" align="center" style="background-color:#7FB4DE;font-family:Verdana;font-weight:bold;height:20px;">
		<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;">


Regular form and VSTA form


Hi All,

Initially we had a browser enabled Infopath form built in Infopath 2007, which was simple and without any code. We published it to a form library and users have been using it to submit forms and there are about 500 forms.

Now due to some business requirements we had to update the form add more fields include VSTA. And now we published and got it uploaded by our Admin to SharePoint, now we want users to submit the form using the new template(or content type) and also able to open old forms using the new template.
