lpCustColors element in CHOOSECOLOR struct

Hello =)

You can see CHOOSECOLOR struct in our latest MASM64 SDK Beta2

--- Code: ---  CHOOSECOLORA STRUCT QWORD
    lStructSize     dd ?
    hwndOwner       dq ?
    hInstance       dq ?
    rgbResult       dd ?
    lpCustColors    dd ?
    Flags           dd ?
    lCustData       dq ?
    lpfnHook        dq ?
    lpTemplateName  dq ?
  CHOOSECOLORA ENDS

  CHOOSECOLORW STRUCT QWORD
    lStructSize     dd ?
    hwndOwner       dq ?
    hInstance       dq ?
    rgbResult       dd ?
    lpCustColors    dd ?
    Flags           dd ?
    lCustData       dq ?
    lpfnHook        dq ?
    lpTemplateName  dq ?
  CHOOSECOLORW ENDS

  IFDEF __UNICODE__
    CHOOSECOLOR equ <CHOOSECOLORW>
  ELSE
    CHOOSECOLOR equ <CHOOSECOLORA>
  ENDIF

--- End code ---

Pay attention to the lpCustColors element; it is DWORD. Now let's look in M$ docs :


--- Code: ---typedef struct tagCHOOSECOLORA {
  DWORD        lStructSize;
  HWND         hwndOwner;
  HWND         hInstance;
  COLORREF     rgbResult;
  COLORREF     *lpCustColors;
  DWORD        Flags;
  LPARAM       lCustData;
  LPCCHOOKPROC lpfnHook;
  LPCSTR       lpTemplateName;
  LPEDITMENU   lpEditInfo;
} CHOOSECOLORA, *LPCHOOSECOLORA;

--- End code ---

As you can see above lpCustColors element is a pointer to a dword value COLORREF. Also the name indicates that it is a long pointer.

@hutch-- we should update sdk and change lpCustColors type from dd to dq. Otherwise ChooseColor function does not work!

Sorry to be slow but I have much to do.

Is this the form you are after ? I don't have a test piece set up to test it.

  CHOOSECOLORA STRUCT QWORD
    lStructSize dd ?
    hwndOwner dq ?
    hInstance dq ?
    rgbResult dd ?
    lpCustColors dq ?           ; pointer to lpCustColors
    Flags dd ?
    lCustData dq ?
    lpfnHook dq ?
    lpTemplateName dq ?
  CHOOSECOLORA ENDS

  CHOOSECOLORW STRUCT QWORD
    lStructSize dd ?
    hwndOwner dq ?
    hInstance dq ?
    rgbResult dd ?
    lpCustColors dq ?           ; pointer to lpCustColors
    Flags dd ?
    lCustData dq ?
    lpfnHook dq ?
    lpTemplateName dq ?
  CHOOSECOLORW ENDS

Exactly hutch, and you have shared the corrected ones  :thumbsup:

Hi,

Yes I can confirm that changing pointer to 64bit's works. Just figured out that and I didn't remember this post at time. After that calling ChooseColor works.

What happened is that Vasily used my old 32 bit WINDOWS.INC file for his own 64 bit file but this one got past him. When I reused Vasily's include file, I missed it as well as I did not have a test piece to test this structure. Most of the rest has been fed through a multitude of test pieces to get them right and I added a lot of stuff to the include file.

Like any include file, there can always be more, especially as Microsoft keep adding things to their includes.
