Question

Below is part of a working normal win32 application created from scratch, not dialog based. it will show the text on the buttom, not top:

hButtonApply = CreateWindow(
    "BUTTON",
    "Reset",
    WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON | BS_BOTTOM,
    95, 130, 120, 40, 
    hWnd, (HMENU)IDC_BUTTON_RESET, hInstance, NULL);
SendMessage(hButtonApply, BM_SETSTYLE, BS_TOP, TRUE);

this however makes it a radio button:

SendMessage(hButtonApply, BM_SETSTYLE, BS_RADIOBUTTON, TRUE);

same for a resource-defined dialog button control.

Subclassing is acceptable. Owner-Drawn Buttons are not acceptable. Thanks, Haotian Yang

Answer 1

Some window styles can only be set during CreateWindow, I guess this might be one of them.

Did you try SetWindowLong ?

Edit:

This seems to work:

LONG style = GetWindowLong(hBtn,GWL_STYLE);
style = (style & ~BS_BOTTOM) | BS_TOP;
SetWindowLong(hBtn,GWL_STYLE,style);
