The information in this article applies to:

• The Microsoft Foundation Classes (MFC), included with: - Microsoft Visual C++, 32-bit Edition, versions 4.0, 4.1, 4.2

SUMMARY

Dialog boxes can be created by using templates in resources or from templates built in memory at run time. The sample contains a class CDlgTempl, which can be used to create these templates in memory. This class provides an easy interface for building and manipulating templates in memory.

MORE INFORMATION

The DLGTEMPLATE and DLGITEMTEMPLATE structures are used for building templates in memory. These structures are not fixed-length structures. They also must aligned properly.

This sample provides a class to build these structures correctly. It also provides the ability to read a template from the resource and then manipulate them. Some of the important functions are:

   SetDlgTemplate  Sets some of the properties of the dialog box.

   SetCaption      Sets the caption for the dialog box.

   AddControl      Adds a control to the template.

   RemoveControl   Removes a control from the template.

   MoveControl     Changes the TAB order of the control.

   LockTemplate    Returns a pointer to memory that contains the dialog
                   box template in a form that can be used with
                   CreateDialogIndirect.

   UnlockTemplate  Should be called to free the memory allocated by
                   LockTemplate.

   CreateTemplateInMemory  Fills the memory passed into the function with
                   the dialog box template.

   FromResource    Initializes the object with information from the
                   template in resource.
