CPushPinButton v1.29

Welcome to CPushPinButton, A freeware MFC PushPin button class. The class is derived from CButton and when used appears as follows:

Usage

To use the class in your code simply include PushPin.cpp and PushPin.h in your project and #include "PushPin.h" in which ever of your modules needs to make calls to the class.
You should also ensure that the bitmaps IDB_PUSHPIN & IDB_PUSHPIN_HELP are copied over into your rc file from the PushPinFrameDemo.rc file.
Create a dialog template with an owner-draw button positioned where you want the push pin button. The size of the button in the template does not matter.
Using Classwizard associate a CBitmap with the button you just created. Then modify the declaration of the variable to make it a CPushPinButton instead of CButton.
To ensure that the class operates correctly when a color scheme change occurs, You should call the ReloadBitmaps method in response to WM_SETTINGCHANGE or WM_WININICHANGE messages.
Your code will need to include MFC either statically or dynamically.
As of v1.23, the class is now designed for VC 2017 or later. They will not compile on earlier releases of VC.

You are allowed to include the source code in any product (commercial, shareware, freeware or otherwise) when your product is released in binary form.
You are allowed to modify the source code in any way you want except you cannot modify the copyright details at the top of each module.
If you want to distribute source code with your application, then you are only allowed to distribute versions released by the author. This is to maintain a single distribution point for the source code.

Added a number of comments to improvde code readibility.
Changed the resouce id of the button bitmaps to more meaningful values.
Class no longer uses message reflection to catch changes in the clicked state. This means that parent classes can now catch the clicked notification.
Code now uses mouse capturing which means that the button appears pressed if you click and hold the left mouse button over the push pin. This gives the pushpin class this standard button behaviour.
