Hi,

I want to use Popup menu without animation. In MSDN (January 1999) I'm find:

Windows 98, Windows NT 5.0 and later: Use one of the following flags to modify the animation of a menu. Value Meaning
TPM_HORNEGANIMATION Animates the menu from left to right.
TPM_HORPOSANIMATION Animates the menu from right to left.
TPM_NOANIMATION Displays menu without animation.
TPM_VERNEGANIMATION Animates the menu from bottom to top.
TPM_VERPOSANIMATION Animates the menu from top to bottom.

I want to use TMP_NOANIMATION, but I can't find where this constant defined (There is no *.h file where this constant defined).

Q: How can I get OS version and disable animation (For W98 or NT50)?

I'm using VC60 with SP3.

Thanks

Hi mahno,

to get state of or disable menu animation you can use SystemParametersInfo(SPI_SETMENUANIMATION) // or SPI_GETMENUANIMATION ...

Unfortunately I didn't found one of these 5 TPM_* defines...

Hi ZOPPO,

Constants: SPI_SETMENUANIMATION, SPI_GETMENUANIMATION are not defined too.

May be U know it's numeric values?

I found them defined in WinUser.h:

#if(WINVER >= 0x0500)
....
#define SPI_GETMENUANIMATION                0x1002
#define SPI_SETMENUANIMATION                0x1003
....
#endif /* WINVER >= 0x0500 */

Hi Zoppo,

I'm found these define too. But, it does not work:

BOOL bAnim = FALSE;
int rc = SystemParametersInfo(0x1003/*SPI_SETMENUANIMATION*/, 0, (PVOID)&bAnim, 0);

If I try to get animation state:

int rc = SystemParametersInfo(0x1002/*SPI_GETMENUANIMATION*/, 0, (PVOID)&bAnim, 0);

I still recieve TRUE. I'm working over W98. Any ideas?

regards,

To set the state pass the value directly, not via pointer:

BOOL bAnim = FALSE;
int rc = SystemParametersInfo(0x1003/*SPI_SETMENUANIMATION*/, 0, (PVOID)bAnim, 0);

hope that helps,
