Consult your Microsoft Win32 Software Development Kit documentation for detailed information about a particular Windows API constant.
Controls are created in one of two ways: dynamically or from a compiled dialog resource. Dynamic creation, which requires that size and position be specified as instantiation parameters, can be used on any type of window. A compiled dialog resource (which specifies both size and location of the control) can be used only with data windows and dialog windows. Additionally, the default state when a control is created depends on the way you placed the control: With dynamic creation, the control remains invisible until you invoke Control:Show(). This allows the program to set up the control correctly (with the correct size, position, and any other parameters), while avoiding the "visual noise" of changing controls. With resource-bound instantiation, the control is automatically shown, without requiring a call to Control:Show().
