SUMMARY
On a Windows 2000-based computer, you can dynamically change the application user interface from left-to-right to right-to-left.



MORE INFORMATION
This can be accomplished by using the following code: // Use ANSI versions of GetWindowLong and SetWindowLong because // Unicode is not needed for these calls. lExStyles = GetWindowLongA(hWnd, GWL_EXSTYLE) ;

// Check whether new layout is opposite the current layout. if(!!(pLState->IsRTLLayout) != !!(lExStyles & WS_EX_LAYOUTRTL)) {              // The following lines update the application layout to                 // be right-to-left or left-to-right, as appropriate. lExStyles ^= WS_EX_LAYOUTRTL ; // Toggle layout.

SetWindowLongA(hWnd, GWL_EXSTYLE, lExStyles) ; // This is to update layout in the client area. InvalidateRect(hWnd, NULL, TRUE) ; }
