how find the value of "_WIN32_WINNT" ? http://msdn.microsoft.com/en-us/library/ms646839%28v=vs.85%29.aspx Code:
sf_ OPENFILENAME
invoke GetOpenFileName,sf_
;from MSDN
;---------
typedef struct tagOFN {
DWORD lStructSize;
HWND hwndOwner;
HINSTANCE hInstance;
.....
.....
LPCTSTR lpstrDefExt;
LPARAM lCustData;
LPOFNHOOKPROC lpfnHook;
LPCTSTR lpTemplateName;
#if (_WIN32_WINNT >= 0x0500) ;<------------------ ??
void *pvReserved;
DWORD dwReserved;
DWORD FlagsEx;
#endif
} OPENFILENAME, *LPOPENFILENAME; _________________ I am not young enough to know everything (Oscar Wilde)-  |

Check http://msdn.microsoft.com/en-us/library/aa383745%28VS.85%29.aspx
In your particular example, it you decide to use those three fields then your code with need Windows 2000 at minimum. |

Code: invoke GetVersionEx,addr buff mov edx,[buff+OSVERSIONINFO.dwMajorVersion] mov eax,[buff+OSVERSIONINFO.dwMinorVersion] |

If you don't use the additional fields on WinXP it is OK, because you'll also pass a lower lStructSize value and hence no attempts to fill the "ghost" fields will be performed by the API function (i.e. the API has backwards compatibility to older software).

Indeed, I had not thought of that, well done Loco !

it works, the places bar is not displayed 
Code: sf_ OPENFILENAME dd 0 ; the three additional fields dd 0 dd 1 ;<----------- FlagsEx mov [sf_.lStructSize],sizeof.OPENFILENAME \ \ + 3*4 ;<-------- ! FlagsEx / OFN_EX_NOPLACESBAR (0x00000001) If this flag is set, the places bar is not displayed _________________ I am not young enough to know everything (Oscar Wilde)- |
