DLGITEMTEMPLATEEX (Windows CE 5.0)
This structure is not defined in any standard header file. The structure definition is provided here to explain the format of an extended template for a dialog box.
For each control in a dialog box, an extended dialog box template has a block of data that uses the DLGITEMTEMPLATEEX format to describe the control. For a description of the format of an extended dialog box template, see DLGTEMPLATEEX.

Members
helpID
Specifies the help context identifier for the control.dwExtendedStyle
Specifies extended styles for a window. This member is not used to create controls in dialog boxes, but applications that use dialog box templates can use it to create other types of windows.style
Specifies the style of the control. This member can be a combination of window style values (such as WS_BORDER) and one or more of the control style values (such as BS_PUSHBUTTON and ES_LEFT).x
Specifies the x-coordinate, in dialog box units, of the upper-left corner of the control. This coordinate is always relative to the upper-left corner of the dialog box's client area.y
Specifies the y-coordinate, in dialog box units, of the upper-left corner of the control. This coordinate is relative to the upper-left corner of the dialog box client area.cx
Specifies the control width, in dialog box units.cy
Specifies the control height, in dialog box units.id
Specifies the control identifier.windowClass
Specifies a variable-length array of 16-bit elements that identifies the window class of the control. If the first element of this array is any value other than 0xFFFF, the system treats the array as a null-terminated Unicode string that specifies the name of a registered window class.If the first element is 0xFFFF, the array has one additional element that specifies the ordinal value of a predefined system class. The ordinal can be one of the atom values shown in the following table.
Value Description 0x0080 Button 0x0081 Edit 0x0082 Static 0x0083 List box 0x0084 Scroll bar 0x0085 Combo box title
Specifies a variable-length array of 16-bit elements that contains the initial text or resource identifier of the control. If the first element of this array is 0xFFFF, the array has one additional element that specifies an ordinal value that identifies a resource, such as an icon, in an executable file. You can use a resource identifier for controls, such as static icon controls, that load and display an icon or other resource rather than text.If the first element is any value other than 0xFFFF, the system treats the array as a null-terminated Unicode string that specifies the initial text.
extraCount
Specifies the number of bytes of creation data that follow this member. If this value is greater than zero, the creation data begins at the next WORD boundary. This creation data can be of any size and format. The control's window procedure must be able to interpret the data. When the system creates the control, it passes a pointer to this data in the lParam parameter of the WM_CREATE message that it sends to the control.
Remarks
An extended template for a dialog box consists of a DLGTEMPLATEEX header followed by a DLGITEMTEMPLATEEX structure for each control in the dialog box.
Each DLGITEMTEMPLATEEX structure must be aligned on a DWORD boundary. The variable-length windowClass and title arrays must be aligned on WORD boundaries. The creation data array, if any, must be aligned on a WORD boundary.
If you specify character strings in the windowClass and title arrays, you must use Unicode strings.
The x, y, cx, and cy members specify values in dialog box units. You can convert these values to screen units (pixels) by using the MapDialogRect function.
Requirements
OS Versions: Windows CE 2.0 and later.
Header: Wingdi.h.
