The 'what' and 'where do I get it' of WTL

What is the Windows Template Library you ask?

Brief history

In the beginning when ATL appeared, developers were happy. We had a way to write fast, small COM components. Well the happiness ended soon after when we found that we had to write code wrappers for any of the window's controls we wanted to use. So MS responded to our plight and gave us WTL, completely unfinished and unsupported (for now).

See WTL Documented for more information.


  • All the power of C++
  • Thin wrappers for the common controls
  • A small but functional Application framework (minus the ever-popular Document-View Architecture)
  • Print and Print Preview support
  • Ports of MFC’s CPoint, CRect, CSize, CString, etc.
  • New Message cracking Macros, conceivably they’re an upgrade of the existing ones.

All this but no documentation! Oh well, we're all professionals and can read code, so for now that will have to suffice.

Where do you get it?

Thanks to Nenad Stefanovic of the WTL development team we now have 2 methods of downloading the WTL source file (Special thanks to Shannon McCoy for pointing this out).

Method 1

Click here to download the WTL source files.

Method 2

Go and get the Platform SDKs.

WTL resides in the Platform SDKs. To find and install WTL you need to download the latest release of the Platform SDKs. In the screen seen below, Expand the Source code tree item and select the Windows Template Library for download.

So, you have the SDKs installed, your ready to go... well almost. Don’t forget to add the WTL include path to Developer Studio. To do that in Developer Studio go to Tools | Options and click on the 'Directories' tab. Once you are there simply add the include path to the 'Include files' list.

What’s in the box?

Let’s take a look at the goodies we got. The WTL is setup so that all the code resides in header files; it's setup this way so that we have full control of what is been tacked into your project.

The Headers

File name Description
atlapp.h Message loop, interfaces, general app stuff
atlcrack.h Message cracker macros atlctrls.h Standard and common control classes
atlctrlw.h Command bar class atlctrlx.h Bitmap button, check list view, and other controls
atlddx.h Data exchange for dialogs and windows
atldlgs.h Common dialog classes, property sheet and page classes
atlframe.h Frame window classes, MDI, update UI classes

DC classes, GDI object classes


ATL ports of CPoint, CRect, CSize, CString, etc.


Printing and print preview

atlres.h Standard resource Ids
atlscrl.h Scrollable windows
atlsplit.h Splitter windows
atluser.h Menu class

The Samples

Directory Description

Multithreaded notepad sample


ATL version of the MDI sample


ATL version of the GuidGen sample

The App-Wizard

File Name Description
AtlApp60.Awx ATL/WTL AppWizard

And of course there is a 'readme.txt', which outlines the class hierarchy of the WTL. Sorry, I said there was no documentation, my bad Smile | :)

Thats it! You got the WTL and your ready to go.

(Thanks, Michael, for new information.)

Here is updated version of the WTLextract.bat
batch file for instalation of WTL from two plain cab
files. New version of the batch extracts also examples
and ATL/WTL wizard. If you have any suggestion, share it!

set psdk=Oct2000
set scommon=893058
set swizard=39162

echo If you want to install also the WTL wizard, download also

echo The size of the cabinet for %psdk% is %swizard% bytes.
echo Place the cabinet(s) to the same directory where this batch is and
