Create two buttons that interact with an editbox

[Arkanops]

Hi all I hope in an answer that could help me about my problem because I'm going crazy.
I'm creating a GUI in Visual C++ .NET and I'd like to split the "Spin Control" in two buttons.

I created an editbox with a spin, only to test the code, and the result is this:


Here the code that I wrote:
The spin control:

CSpinButtonCtrl *spin = (CSpinButtonCtrl*)GetDlgItem(IDC_SPIN_ROTOR_TEST);
spin->SetRange(0, 25);
spin->SetPos(0);
GetDlgItem(IDC_ROTORTEXT)->SetWindowText("A");

The letters in the editbox:

void CTestDlg::onShowposSpinStr(NMHDR* pNMHDR, LRESULT* pResult)
{
int nNewPos;
char szNumber[][16] =
{
"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "W", "V", "X", "Y", "Z"
};
NM_UPDOWN *pNMUpDown = (NM_UPDOWN*) pNMHDR;

nNewPos = pNMUpDown->iPos + pNMUpDown->iDelta;

if(nNewPos >= 0 && nNewPos <= 25)
{
GetDlgItem(IDC_ROTOR3TEXT)->SetWindowText(szNumber[nNewPos]);
}
*pResult = 0;
}

But now I have to split the spin into two buttons that interact with the editbox, to increase/decrease the letters, like this:


I have no idea on how I can do this...
Please someone help me, I'm desperate.

I know there is a spin control already in VS -- its under active x stuff --
not sure about your version.
