我有运行其他应用程序的HTTP服务器应用程序(作为桌面应用程序运行的服务应用程序),之后应该激活另一个应用程序的窗口。计算机X包含所有应用程序当我从计算机X的Opera网络浏览器中运行 http://192.168.16.21:225/command/TTaskType.ttTestTask 时,我的WinActivate
功能正常运行。当我从计算机Y运行 http://192.168.16.21:225/command/TTaskType.ttTestTask 时,窗口未激活。无调试输出返回错误(我打印出FLastErrorY)。我甚至尝试以管理员身份运行HTTP服务器。 我还能尝试什么?
function WinActivate(const AWinTitle: string): boolean;
var
_WindowHandle: HWND;
_KeyboardState: TKeyboardState;
begin
ResetError;
_WindowHandle := FindWindow(nil, PWideChar(AWinTitle));
FLastError := GetLastError;
SetCursorPos(10, 12);
OutputDebugString(PWideChar('FLastError1: ' + IntTostr(FLastError) +
', _WindowHandle: ' + Format('%.8X', [_WindowHandle]) + ' ' + DateTimeToStr(Now)));
if _WindowHandle <> 0 then
begin
//ShowWindow(_WindowHandle, SW_MINIMIZE);
if IsIconic(_WindowHandle) then
begin
ShowWindow(_WindowHandle, SW_RESTORE);
ResetError;
Result := IsIconic(_WindowHandle);
if Result then
Result := WinWaitActive(AWinTitle, 1000);
end
else
Result := SetForegroundWindow(_WindowHandle);
OutputDebugString(PWideChar('FLastErrorX: ' + IntTostr(FLastError) +
', _WindowHandle: ' + Format('%.8X', [_WindowHandle]) + ' ' + DateTimeToStr(Now)));
if not Result then
begin
FLastError := GetLastError;
OutputDebugString(PWideChar('FLastError2: ' + IntTostr(FLastError) +

// Applications might lock focus, so, hack it around
GetKeyBoardState(_KeyboardState);
ShowWindow(_WindowHandle, SW_SHOWNORMAL);
SystemParametersInfo(SPI_SETFOREGROUNDLOCKTIMEOUT, 0, 0, SPIF_UPDATEINIFILE);
if _KeyboardState[VK_MENU] <> 1 then

答案 0 :(得分:0)
所以,我发现什么是错的。我知道AutoHotkey有窗口激活功能。我已经下载了它的源代码,并且窗口激活代码编写得很好并且已经过评论。所以我使用AutoHotkey构建了一个测试应用程序,我的窗口没有被激活。我发现这是因为没有活跃的用户登录。
