v | Autoscroll: Text is automatically scrolled upwards if ENTER key is pressed on the last displayed line. This style also enables scrolling in the absence of a vertical scroll bar (e.g. via cursor keys or mouse wheel). Note An edit area with a vertical scroll bar is implicitly autoscrollable.

#### Possible Value for Group Frame Controls

#### Possible Value for Image Controls

Value | Meaning
--- | ---
s | Scaled. If the required width or height of the rendered image differ from the width or height of the image(s) taken from the image file, the images are scaled, rather than being either extended in the background color or truncated.
T | Transparent. Image is rendered transparently. For bitmap image files (*.bmp), bitmap pixels matching the background color are not drawn. If the background color is specified as "default", the color of the first pixel in the bitmap is assumed to be the background color. For icon image files (*.ico), where the background color is "default" and no scaling needs to be performed on the image, the transparency mask provided with the icon is used. Otherwise, the icon's bitmap is handled as for bitmap image files and the transparency mask is ignored.
C | Composite image. Image bitmap file assumed to consist of multiple images joined together horizontally into one large bitmap, based on the image list's ITEM-H and ITEM-W attributes, or (if zero) the system small icon size if the image list's "Small images (S)" style is specified, or the system large icon size (typically 32 by 32 pixels) if the image list's "Large images (L)" style is specified. If none of these are specified, the system small icon size (typically 16 by 16 pixels) is assumed. This style cannot be used for icon image files.
O | Overlay image. An overlay images is an images that may be superimposed on the base image displayed for an item. Overlay images may be specified via the OVERLAY and/or OVERLAY-INDEX attributes, and are always implicitly rendered transparently.

#### Possible Value for Image List Controls

Value | Meaning
--- | ---
L | Large images. Indicates that the image list consists of images corresponding to the system large icon size (typically 32 by 32 pixels). This should be set if the image list is used to source large icons for a control (e.g., for the Icon view mode of a list view control).
S | Small images. Indicates that the image list consists of images corresponding to the system small icon size (typically 16 by 16 pixels). This should be set if the image list is used to provide small icons for a control (e.g., for a tree view control).

Notes:

1. Both of the above styles may be specified, in which case the image list control consists of both large and small images (e.g. for list view controls).
2. If neither of the above styles are specified, the image size is determined by the ITEM-W and ITEM-H attributes. If either of these is zero, the system small icon width or height (respectively) is assumed.

Note
When you edit the STYLE attribute value in the scroll bar control attributes window, setting "h" instead of "v" and vice versa, the RECTANGLE-H and RECTANGLE-W attribute values are exchanged.

k | Arrow keys (default). Causes the control to increment or decrement the position when the Up Arrow and Down Arrow keys are pressed, respectively.
n | No thousands (default). Thousands separators are not used. For example, "1,200,000" is displayed as "1200000" in the buddy input field control (if any). Note This option only has an effect if the "Set buddy (s)" STYLE is also set.
t | Hot tracking. Causes the up and down arrow buttons to be highlighted when the mouse cursor moves over them. Note This option is implicitly set if Windows XP styles are in use.
