There is only one scroll bar
When I push once the up or down arrows of the vertical scroll bar I get a multiple WM_VSCROLL, sometimes 3, 5, 10... How can avoid this behavior? Why is this error?
... case WM_VSCROLL: { switch(LOWORD(wParam)) { case SB_LINEUP: curPos-=10; break; case SB_LINEDOWN: curPos+=10; break; case SB_PAGEUP: curPos -= 64; break; case SB_PAGEDOWN: curPos += 64; break; case SB_THUMBPOSITION: newPos = (HIWORD(lParam)); break; default: NewPos = curPos; break; } si.cbSize = sizeof(si); si.fMask = SIF_POS; si.nPos = curPos; SetScrollInfo(hDialogHandle, SB_VERT, &si, TRUE); InvalidateRect( NULL, TRUE ); MessageBox(..."WM_VSCROLL"... ); ... } break;
