MFC spin control scroll up and down

To achieve this, you only need to capture the udn_deltapod message of spin control, as shown in the following example:

Ondeltaposspin1 (nmhdr * pnmhdr, lresult * presult)
{
Lpnmupdown pnmupdown = reinterpret_cast <lpnmupdown> (pnmhdr );
// Todo: add control notifications hereProgramCode

If (pnmupdown-> idelta = 1) // if this value is 1, the spin arrow is clicked.
{

// Add the numeric value in the edit box
}
Else if (pnmupdown-> idelta =-1) // if this value is-1, it means you have clicked the up arrow of spin.
{
// Reduce the numeric value in the edit box
}

}
