The code was developed on vc++ visual studio 2003 and now has been migrated to vc++ visual studio 2010 and maybe because of it there seems to have occured a very peculiar behavior to the date/time control's spin control property, the code works absolutely fine on windows xp sp3 and below but behaves opposite to the way it should on windows 7 and now 8, the reason for it is unknown. when the up button is pressed the data is actually decreased instead of getting increased same holds for the down button and sometime there is a delay of few seconds for the data to get updated.

.NET Framework 4.0

void CDateTimeFunctionControl::OnNotifyDeltaPos(NMHDR *pNMHDR, LRESULT *pResult)
{
    NMUPDOWN *pNMUD = (NMUPDOWN*) pNMHDR;

    static int i = 0;
    TRACE("%d.\t%d:\tOnNotifyDeltaPos()\n", i++, pNMUD->iDelta);

    DWORD vKey;

    if (pNMUD->iDelta < 0)
    {
        vKey = VK_DOWN;
        pNMUD->iDelta = - pNMUD->iDelta;
    }
    else if (pNMUD->iDelta > 0)
    {
        vKey = VK_UP;
    }
    else
        return;

    for (int j = 0; j < pNMUD->iDelta; j++)
    {
        PostMessage(WM_KEYDOWN, vKey, 0x00000001);
        PostMessage(WM_KEYUP, vKey, 0x10000001);
    }

Hello,

Thanks for the report. We have investigated and found that the problem is in your application code, in the handling of the NMUPDOWN message. Your code has a comment ("fix bugs in the datetime picker control that ships with IE4.") and that area of code should be changed to handle the new control behavior. Alternatively you can remove the #pragma in the stdafx.h file that adds the manifest dependency on the Common Control DLL version 6.0.
