窗体前置

下面是我在项目中常用的将窗口置前的函数，你试下：

Delphi/Pascal code
function BringWindowToTopEx(hWnd: HWND): Boolean;
begin
if IsIconic(hWnd) then
ShowWindow(hWnd, SW_RESTORE);
if GetForegroundWindow <> hWnd then
SetForegroundWindow(hWnd);//enabled
//BringWindowToTop(hWnd);//not enabled
//ForceForegroundWindow(hWnd);//enabled
{SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE);
SetWindowPos(hWnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE);//enabled}
//SwitchToThisWindow(hWnd, True);//enabled
Result := GetForegroundWindow = hWnd;
end;

function BringWindowToTopMost(hWnd: HWND; bTopMost: Boolean): Boolean;
begin
if IsIconic(hWnd) then
ShowWindow(hWnd, SW_RESTORE);
if bTopMost then
SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE)
else
SetWindowPos(hWnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE or SWP_NOSIZE);
end;

function BringWindowToTopXY(hWnd: HWND; X, Y: Integer;
hWndInsertAfter: HWND): Boolean;
begin
Result := BringWindowToTopEx(hWnd);
Result := SetWindowPos(hWnd, hWndInsertAfter, X, Y, 0, 0, SWP_NOSIZE)
and Result;
end;
