it seems u have to calculate the width of the window and control and accordingly place it using MoveWindow function. -Sarath

No there is not. You were given the correct answer before.

Here's some code to do it. Call "CenterChildren" with a HWND. ------------------------------------------------------------- BOOL CALLBACK MeasureChildrenBoundsProc(HWND hwnd, LPARAM lParam) { RECT *pRectUnion = reinterpret_cast(lParam); RECT RectControl; GetWindowRect(hwnd, &RectControl); HWND hParent = GetParent(hwnd); MapWindowPoints(NULL, hParent, reinterpret_cast(&RectControl), 2); UnionRect(pRectUnion, pRectUnion, &RectControl); return TRUE; } BOOL CALLBACK OffsetChildrenProc(HWND hwnd, LPARAM lParam) { POINT *pPoint = reinterpret_cast(lParam); RECT RectControl; GetWindowRect(hwnd, &RectControl); HWND hParent = GetParent(hwnd); MapWindowPoints(NULL, hParent, reinterpret_cast(&RectControl), 2); SetWindowPos( hwnd, NULL, RectControl.left+pPoint->x, RectControl.top+pPoint->y, 0, 0, SWP_NOZORDER|SWP_NOSIZE ); return TRUE; } void CenterChildren(HWND hWnd) { // Calculate the bounding box around our children. RECT rc = {0}; EnumChildWindows(hWnd, &MeasureChildrenBoundsProc, reinterpret_cast(&rc)); // Move the children. RECT RectParent; GetClientRect(hWnd, &RectParent); int ParentWidth = RectParent.right-RectParent.left; int ParentHeight = RectParent.bottom-RectParent.top; int ChildrenWidth = rc.right-rc.left; int ChildrenHeight = rc.bottom-rc.top; POINT offset = {(ParentWidth-ChildrenWidth)/2-rc.left, (ParentHeight-ChildrenHeight)/2-rc.top}; EnumChildWindows(hWnd, &OffsetChildrenProc, reinterpret_cast(&offset)); } Steve
