This function changes an attribute of the window specified by the hwnd parameter.
hwnd
Identifies the window to be modified.
nIndex
Specifies the byte offset of the word to be changed.
wNewWord
Specifies the replacement value.
The return value specifies the previous value of the specified word.
To access any extra two-byte values allocated when the window-class structure was created, use a positive byte offset as the index specified by the nIndex parameter, starting at zero for the first two-byte value in the extra space, two for the next two-byte value and so on.
Use the SetWindowLong function to set the following system-defined values:
| Old SetWindowWord Index | New SetWindowLong Index |
| GWW_HINSTANCE | GWL_HINSTANCE |
| GWW_HWNDPARENT | GWL_HWNDPARENT |
| GWW_ID | GWL_ID |
