I tried this format:

C++

case IDC_BTN_BUYSTOP:

if ( SendMessage( GetDlgItem(hDlg1, IDC_RADIO1), BM_GETCHECK, 0,0 )== BST_CHECKED)
				nSel = 40; 
			
else if ( SendMessage( GetDlgItem(hDlg1, IDC_RADIO2), BM_GETCHECK, 0,0 )== BST_CHECKED)
				nSel = 50; 

			SetWindowLong(hDlg1, GWL_USERDATA, nSel);
                     
int res= GetWindowLong(hDlg1, GWL_USERDATA);

break;

return zero. tried this:

C++

case IDC_BTN_BUYSTOP:

if ( SendMessage( GetDlgItem(hDlg1, IDC_RADIO1), BM_GETCHECK, 0,0 ))
				nSel = 40; 
			
else if ( SendMessage( GetDlgItem(hDlg1, IDC_RADIO2), BM_GETCHECK, 0,0 ))
				nSel = 50; 

			SetWindowLong(hDlg1, GWL_USERDATA, nSel);
                     
int res= GetWindowLong(hDlg1, GWL_USERDATA);

break;

return zero. and another

C++

case IDC_BTN_BUYSTOP:

if ( ::SendMessage( GetDlgItem(hDlg1, IDC_RADIO1), BM_GETCHECK, 0,0 ))
				nSel = 40; 
			
else if ( ::SendMessage( GetDlgItem(hDlg1, IDC_RADIO2), BM_GETCHECK, 0,0 ))
				nSel = 50; 

			SetWindowLong(hDlg1, GWL_USERDATA, nSel);
                     
int res= GetWindowLong(hDlg1, GWL_USERDATA);

break;

return zero again.

I just tried this and it works fine; where are you getting zero returned?

You should add {} to your case statement, since you define integer variable res.

I didn't see any code that returned anything. Where is your 'return res;'?

The SendMessage() calls return a value...

There is more than one format that is correct... but your problem statement doesn't specify what you're doing and when you encounter the problem. Do you even know that you're getting to the SendMessage() calls?
