The following table shows window control styles that are supported by Windows CE.
Check box styles |
Description |
BS_3STATE |
Creates a check box in which the box can be unavailable as well as selected or cleared. Use the unavailable state to show that the state of the check box is not determined. |
BS_AUTO3STATE |
Creates a three-state check box in which the state cycles through selected, unavailable, and cleared each time the user selects the check box. |
BS_AUTOCHECKBOX |
Creates a check box in which the check state switches between selected and cleared each time the user selects the check box. |
BS_CHECKBOX |
Creates a small, empty check box with a label displayed to the right of it. To display the text to the left of the check box, combine this flag with the BS_RIGHTBUTTON style. |
BS_LEFT |
Left-aligns the text in the button rectangle on the right side of the check box. |
BS_RIGHT |
Right-aligns text in the button rectangle on the right side of the check box. |
BS_RIGHTBUTTON |
Positions a check box square on the right side of the button rectangle. |
WS_TABSTOP |
Turns the control into a tab stop, which enables the user to select the control by tabbing through the controls in a dialog box. |
Combo box styles |
Description |
CBS_AUTOHSCROLL |
Automatically scrolls the text in an edit control to the right when the user types a character at the end of the line. If this style is not set, only text that fits within the rectangular boundary is enabled. |
CBS_DISABLENOSCROLL |
Shows a disabled vertical scroll bar in the list box when the box does not contain enough items to scroll. Without this style, the scroll bar is hidden when the list box does not contain enough items. |
CBS_DROPDOWN |
Displays only the edit control by default. The user can display the list box by selecting an icon next to the edit control. |
CBS_DROPDOWNLIST |
Displays a static text field that displays the current selection in the list box. |
CBS_LOWERCASE |
Converts to lowercase any uppercase characters that are typed into the edit control of a combo box. |
CBS_NOINTEGRALHEIGHT |
Specifies that the combo box will be exactly the size specified by the application when it created the combo box. Usually, Windows CE sizes a combo box so that it does not display partial items. |
CBS_OEMCONVERT |
Converts text typed in the combo box edit control from the Windows CE character set to the OEM character set and then back to the Windows CE set. This style is most useful for combo boxes that contain file names. It applies only to combo boxes created with the CBS_DROPDOWN style. |
CBS_SORT |
Sorts strings that are typed into the list box. |
CBS_UPPERCASE |
Converts to uppercase any lowercase characters that are typed into the edit control of a combo box. |
WS_TABSTOP |
Turns control into a tab stop, which enables the user to select the control by tabbing through the controls in a dialog box. |
Edit control styles |
Description |
ES_AUTOHSCROLL |
Automatically scrolls text to the right by 10 characters when the user types a character at the end of the line. When the user presses the ENTER key, the control scrolls all text back to the zero position. |
ES_AUTOVSCROLL |
Scrolls text up one page when the user presses the ENTER key on the last line. |
ES_CENTER |
Centers text in a multiline edit control. |
ES_COMBOBOX |
Indicates that the edit control is part of a combo box |
ES_LEFT |
Left-aligns text. |
ES_LOWERCASE |
Converts all characters to lowercase as they are typed into the edit control. |
ES_MULTILINE |
Designates a multiline edit control. The default is a single-line edit control.
When the multiline edit control is in a dialog box, the default response to pressing the ENTER key is to activate the default button. To use the ENTER key as a carriage return, use the ES_WANTRETURN style.
When the multiline edit control is not in a dialog box and the ES_AUTOVSCROLL style is specified, the edit control shows as many lines as possible and scrolls vertically when the user presses the ENTER key. If you do not specify ES_AUTOVSCROLL, the edit control shows as many lines as possible and beeps if the user presses the ENTER key when no more lines can be displayed.
If you specify the ES_AUTOHSCROLL style, the multiline edit control automatically scrolls horizontally when the caret goes past the right edge of the control. To start a new line, the user must press the ENTER key. If you do not specify ES_AUTOHSCROLL, the control automatically wraps words to the beginning of the next line when necessary. A new line is also started if the user presses the ENTER key. The window size determines the position of the word wrap. If the window size changes, the word wrapping position changes and the text is redisplayed.
Multiline edit controls can have scroll bars. An edit control with scroll bars processes its own scroll bar messages. Edit controls without scroll bars scroll as described in the previous paragraphs and process any scroll messages that are sent by the parent window.
|
ES_NOHIDESEL |
Negates the default behavior for an edit control. The default behavior hides the selection when the control loses the input focus and inverts the selection when the control receives the input focus. If you specify ES_NOHIDESEL, the selected text is inverted, even if the control does not have the focus. |
ES_NUMBER |
Accepts into the edit control only digits to be typed. |
ES_OEMCONVERT |
Converts text typed in the edit control from the Windows CE character set to the OEM character set and then converts it back to the Windows CE set. This style is most useful for edit controls that contain file names. |
ES_PASSWORD |
Displays an asterisk (*) for each character that is typed into the edit control. You can use the EM_SETPASSWORDCHAR message to change the displayed character. |
ES_READONLY |
Prevents the user from typing or editing text in the edit control. |
ES_RIGHT |
Right-aligns text in a multiline edit control. |
ES_UPPERCASE |
Converts all characters to uppercase as they are typed into the edit control. |
ES_WANTRETURN |
Specifies that a carriage return be inserted when the user presses the ENTER key while typing text into a multiline edit control in a dialog box. If you do not specify this style, pressing the ENTER key has the same effect as pressing the dialog box’s default push button. This style has no effect on a single-line edit control. |
WS_TABSTOP |
Turns the control into a tab stop, which enables the user to select the control by tabbing through the controls in a dialog box. |
List box styles |
Description |
LBS_DISABLENOSCROLL |
Shows a disabled vertical scroll bar for the list box when the box does not contain enough items to scroll. If you do not specify this style, the scroll bar is hidden when the list box does not contain enough items. |
LBS_EXTENDEDSEL |
Enables the user to select multiple items by using the SHIFT key and the mouse or hot keys. |
LBS_MULTICOLUMN |
Specifies a multicolumn list box that the user scrolls through horizontally. You set the width of the columns by using the LB_SETCOLUMNWIDTH message. |
LBS_MULTIPLESEL |
Turns string selection on or off each time a user taps or double-taps a string in the list box. A user can select any number of strings simultaneously. |
LBS_NOINTEGRALHEIGHT |
Specifies that the list box will be exactly the size specified by the application when it created the list box. Usually, Windows CE sizes a list box so that it does not display partial items. |
LBS_NOREDRAW |
Ensures that the list box appearance is not automatically updated when changes are made. You can change this style by sending a WM_SETREDRAW message. |
LBS_NOSEL |
Specifies that the user can view list box strings but cannot select them. |
LBS_NOTIFY |
Notifies the parent window when the user taps or double-taps a string in the list box. |
LBS_SORT |
Sorts strings in the list box alphabetically. |
LBS_STANDARD |
Sorts strings in the list box alphabetically. The parent window receives an input message when the user taps or double-taps a string. The list box has borders on all sides. |
LBS_USETABSTOPS |
Enables a list box to recognize and expand tab characters when drawing its strings. The default tab positions are 32 dialog box units. A dialog box unit is equal to one-fourth of the current dialog box base-width unit. Windows CE calculates these units based on the height and width of the current system font. |
LBS_WANTKEYBOARDINPUT |
Specifies that the owner of the list box receives WM_VKEYTOITEM messages when the user presses a key and the list box has the input focus. This enables an application to perform special processing on the keyboard input. |
WS_TABSTOP |
Turns the control into a tab stop, which enables the user to select the control by tabbing through the controls in a dialog box. |
Push button styles |
Description |
BS_BOTTOM |
Places the text at the bottom of the button rectangle. |
BS_CENTER |
Centers the text horizontally in the button rectangle. |
BS_DEFPUSHBUTTON |
Creates a push button with a heavy black border. If the button is in a dialog box, the user can select the button by pressing the ENTER key, even when the button does not have the input focus. This style is useful for enabling the user to quickly select the most likely option, or default. |
BS_LEFT |
Left-aligns the text in the button rectangle. |
BS_NOTIFY |
Enables a button to send BN_DBLCLK, BN_KILLFOCUS, and BN_SETFOCUS notification messages to its parent window. Note that the button sends the BN_CLICKED notification message regardless of whether it has this style. |
BS_OWNERDRAW |
Creates an owner-drawn button. The owner window receives a WM_MEASUREITEM message when the button is created and a WM_DRAWITEM message when a visual aspect of the button has changed. |
BS_PUSHBUTTON |
Creates a push button that posts a WM_COMMAND message to the owner window when the user clicks the button. |
BS_RIGHT |
Right-aligns text in the button rectangle. |
BS_TOP |
Places text at the top of the button rectangle. |
BS_VCENTER |
Vertically centers text in the button rectangle. |
WS_TABSTOP |
Turns the control into a tab stop, which enables the user to select the control by tabbing through the controls in a dialog box. |
Radio button styles |
Description |
BS_AUTORADIOBUTTON |
Creates a radio button that, when selected by a user, clears all other buttons in the same group. |
BS_LEFT |
Left-aligns the text in the button rectangle on the right side of the check box. |
BS_RADIOBUTTON |
Creates a small circle with a label displayed to the right of it. To display the text to the left of the circle, combine this flag with the BS_RIGHTBUTTON style. |
BS_RIGHT |
Right-aligns the text in the button rectangle on the right side of the check box. |
BS_RIGHTBUTTON |
Positions a check box square on the right side of the button rectangle. |
WS_TABSTOP |
Turns the control into a tab stop, which enables the user to select the control by tabbing through the controls in a dialog box. |
Static control styles |
Description |
SS_BITMAP |
Specifies that a bitmap will be displayed in the static control. The text is the name of a bitmap that is defined elsewhere in the resource file, not a file name. The style ignores the nWidth and nHeight parameters; the control automatically sizes itself to accommodate the bitmap. |
SS_CENTER |
Specifies a simple rectangle and centers the error value text in the rectangle. Windows CE formats the text before display. The control automatically wraps words that extend past the end of a line to the beginning of the next centered line. |
SS_CENTERIMAGE |
Specifies that the midpoint of a static control with the SS_BITMAP style will remain fixed when you resize the control. The four sides are adjusted to accommodate a new bitmap. If the bitmap is smaller than the control’s client area, the rest of the client area is filled with the color of the pixel in the upper-left corner of the bitmap. |
SS_ICON |
Specifies that an icon will be displayed in the static control. The text is the name of an icon defined elsewhere in the resource file, not a file name. The style ignores the nWidth and nHeight parameters; the icon automatically sizes itself. |
SS_LEFT |
Specifies a rectangle and left-aligns the text in the rectangle. Windows CE formats the text before display. The control automatically wraps words that extend past the end of a line to the beginning of the next left-aligned line. |
SS_LEFTNOWORDWRAP |
Specifies a rectangle and left-aligns the text in the rectangle. Tabs are expanded, but words are not wrapped. Text that extends past the end of a line is clipped. |
SS_NOPREFIX |
Prevents interpretation of any ampersand (&) characters in the control’s text as accelerator prefix characters.
An application can combine SS_NOPREFIX with other styles by using the bitwise OR (|) operator. This can be useful when file names or other strings that might contain an ampersand (&) must be displayed within a static control in a dialog box.
|
SS_NOTIFY |
Sends the parent window the STN_CLICKED notification when the user clicks the control. |
SS_RIGHT |
Specifies a rectangle and right-aligns the specified text in the rectangle. Windows CE formats the text before display. The control automatically wraps words that extend past the end of a line to the beginning of the next right-aligned line. |
Trackbar control styles |
Description |
TBS_AUTOTICKS |
The trackbar control will have a tick mark for each increment in its range of values. |
TBS_BOTH |
The trackbar control will display tick marks on both sides of the control. This will be both top and bottom when used with TBS_HORZ or both left and right if used with TBS_VERT. |
TBS_BOTTOM |
The trackbar control will display tick marks below the control. This style is only valid with TBS_HORZ. |
TBS_ENABLESELRANGE |
The trackbar control can display a selection range only. The tick marks at the starting and ending positions of a selection range are displayed as triangles (instead of vertical dashes), and the selection range is highlighted. |

The trackbar control will display tick marks above the control. This style is only valid with TBS_HORZ. |
TBS_VERT |
The trackbar control will be oriented vertically. This is the default orientation. |
Basic common control styles |
Description |
CCS_ADJUSTABLE |
Enables a toolbar’s built-in customization features, which enable the user to drag a button to a new position or to remove a button by dragging it off the toolbar. In addition, the user can double-click the toolbar to display the Customize Toolbar dialog box, which enables the user to add, delete, and rearrange toolbar buttons. |
CCS_BOTTOM |
Causes the control to position itself at the bottom of the parent window’s client area and sets the width of the control to be the same as the parent window’s width. Status windows have this style by default. |
CCS_LEFT |
Causes the control to display vertically on the left side of the parent window. |
CCS_NODIVIDER |
Prevents a 2-pixel highlight from being drawn at the top of the control. |
CCS_NOMOVEX |
Causes the control to resize and move itself vertically, but not horizontally, in response to a WM_SIZE message. This message does not apply if your control has the CCS_NORESIZE style. |
CCS_NOMOVEY |

CCS_NOPARENTALIGN |
Prevents the control from automatically moving to the top or bottom of the parent window. Instead, the control keeps its position within the parent window despite changes to the size of the parent. If the application also uses the CCS_TOP or CCS_BOTTOM styles, it adjusts the height to the default, but does not change the position and width of the control. |
CCS_NORESIZE |
Prevents the control from using the default width and height when setting its initial size or a new size. Instead, the control uses the width and height that is specified in the request for creation or sizing. |
CCS_RIGHT |
Causes the control to display vertically on the right side of the parent window. |
CCS_TOP |
Causes the control to position itself at the top of the parent window client area and matches the width of the control to the width of the parent window. Toolbars have this style by default. |
CCS_VERT |
Causes the control to display vertically. |
Date and time picker styles |
Description |
DTS_APPCANPARSE |
Enables the owner to parse user input. When a date time picker (DTP) control has this style, a user can make changes within the client area of the control by pressing the F2 key. The control sends a DTN_USERSTRING notification message when the user is finished editing. |
DTS_LONGDATEFORMAT |
Displays the date in long format. The default format string for this style is defined by LOCALE_SLONGDATEFORMAT, which produces output like “Friday, April 19, 1998.” |
DTS_SHORTDATEFORMAT |

Rebar styles |
Description |
CCS_VERT |
Causes the control to appear vertically at the left side of the parent window. |
RBBS_NOGRIPPER |
Creates a rebar band that displays no gripper. This style applies to individual bands, not to the entire rebar. Windows CE is the only Windows-based OS that supports the RBS_NOGRIPPER style for rebar controls. |
RBS_AUTOSIZE |
Specifies that the layout of a band will automatically change when the size or position of its control changes. When the layout changes, the control sends an RBN_AUTOSIZE notification. |
RBS_BANDBORDERS |

TCS_FLIP |
Flips all tabs from top to bottom or left to right. |
TCS_FOCUSNEVER |
Creates a tab control that never receives the input focus. |
TCS_FOCUSONBUTTONDOWN |
Specifies that a given tab, when selected, receives the input focus. |
TCS_FORCEICONLEFT |
Aligns an icon with the left edge of a fixed-width tab. This style can only be used with the TCS_FIXEDWIDTH style. |
TCS_FORCELABELLEFT |
Aligns a label with the left edge of a fixed-width tab; that is, it displays the label immediately to the right of the icon instead of centering it. This style can only be used with the TCS_FIXEDWIDTH style, and it implies the TCS_FORCEICONLEFT style. |
TCS_MULTILINE |
Displays multiple rows of tabs, if necessary, so that all tabs are visible at once. |
