用TerminateProcess把一个进程结束后有个问题,就是如果该程序在托盘有图标的话,这个图标并不会在它被结束时也消失。当然你用鼠标从上面移过可以解决这个问题,但本人在用自己的刷新辅助软件“疯狂刷新”的时候,每5分钟结束一次,一天下来如果不动电脑,就会在托盘区生成NNN个死图标,即使你拚命去点,也要点半天才能全部消除。有没有办法一下子搞定它呢?答案是肯定的,在网上搜了很久……用Delphi编写几行代码搞定。
添加自定义类型,用作判断系统类型,
type
TOSVersion = (osUnknown, os95, os98, osME, osNT3, osNT4, os2K, osXP, os2K3);
添加自定义函数过程
function GetOS: TOSVersion; //获得系统类型,用来取得托盘句柄
var
OS: TOSVersionInfo;
begin
ZeroMemory(@OS, SizeOf(OS));
OS.dwOSVersionInfoSize := SizeOf(OS);
GetVersionEx(OS);
Result := osUnknown;
if OS.dwPlatformId = VER_PLATFORM_WIN32_NT then begin
case OS.dwMajorVersion of
3: Result := osNT3;
4: Result := osNT4;
5: begin
case OS.dwMinorVersion of
0: Result := os2K;
1: Result := osXP;
2: Result := os2K3;
end;
end;
end;
end
else if (OS.dwMajorVersion = 4) and (OS.dwMinorVersion = 0) then
Result := os95
else if (OS.dwMajorVersion = 4) and (OS.dwMinorVersion = 10) then
Result := os98
else if (OS.dwMajorVersion = 4) and (OS.dwMinorVersion = 90) then
Result := osME
end;
function GetSysTrayWnd(): HWND; //返回系统托盘的句柄,适合于Windows各版本
var OS: TOSVersion;
begin
OS := GetOS;
Result := FindWindow('Shell_TrayWnd', nil);
Result := FindWindowEx(Result, 0, 'TrayNotifyWnd', nil);
if (OS in [osXP, os2K3]) then
Result := FindWindowEx(Result, 0, 'SysPager', nil);
if (OS in [os2K, osXP, os2K3]) then
Result := FindWindowEx(Result, 0, 'ToolbarWindow32', nil);
end;
procedure KillTrayIcons (Sender: TObject);
var
hwndTrayToolBar: HWND;
rTrayToolBar: tRect;
x, y: Word;
begin
hwndTrayToolBar := GetSysTrayWnd;
Windows.GetClientRect(hwndTrayToolBar, rTrayToolBar);
for x := 1 to rTrayToolBar.right - 1 do begin
for y := 1 to rTrayToolBar.bottom - 1 do begin
SendMessage(hwndTrayToolBar, WM_MOUSEMOVE, 0, MAKELPARAM(x, y));
end;
end;
end;
//调用 KillTrayIcons(self) 过程就可以瞬间清除所有无用的托盘图标了。
经过本人测试,Delphi7+XP系统下确实可以用。
