The HBITMAP is a handle to a bitmap, a memory-resident structure that contains no file information, but instead actually describes the layout and data values for a loaded image.
You'd use the GetDIBits() API call to retrieve the actual bitmap into a buffer.

>PARAMETERS:
>p_LabelPath - The path and file name for the label.
>p_LabelDesc - A pointer to a string which is used to obtain the description for the label.
>p_LabelDescMaxLen - A pointer to an unsigned long used to get or supply the maximum length for the p_LabelDesc field. If p_LabelDesc is NULL, p_LabelDescMaxLen will be set to the length of the value (including the NULL terminator) which would have been copied into p_LabelDesc had it not been NULL. Otherwise it will copy only this number of characters. If it is NULL it will not use this value and the number of characters copied to p_LabelDesc will not be limited.

>p_Image - This is a pointer to a bitmap which is a picture of the label design.
