ImageList_SetImageCount function (commctrl.h)

Resizes an existing image list.

Syntax

BOOL ImageList_SetImageCount(
  [in] HIMAGELIST himl,
  [in] UINT       uNewCount
);

Parameters

[in] himl

Type: HIMAGELIST

A handle to the image list that will be resized.

[in] uNewCount

Type: UINT

A value specifying the new size of the image list.

Return value

Type: BOOL

Returns nonzero if successful, or zero otherwise.

Remarks

If an application expands an image list with this function, it must add new images by using the ImageList_Replace function. If your application does not add valid images at the new indexes, draw operations that use the new indexes will be unpredictable.

If you decrease the size of an image list by using this function, the truncated images are freed.
