<div>
I have just realised that I have a handler for this button already:<br />
<br />
DDX_Control(pDX, IDC_BUTTON_1, m_button1);<br />
<br />
could this be causing problems???

CBitmapButton  SubclassDlgItem throwing an assert

Smartphones run using a variety of operating systems -- Android, iOS and Windows Mobile most commonly -- and an even wider variety of programming languages, including Objective-C, Java, Visual C#, C++ and .NET, not to mention HTML5 and JavaScript, and cross-platform frameworks such as PhoneGap.

Smartphone Programming

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.

System Programming

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
