『楼 主』:
[求助]懂delph的朋友能否帮个忙？帮忙编译成exe文件 谢谢

用Delphi瞬间消除无用托盘图标2008-10-05 11:52
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 过程就可以瞬间清除所有无用的托盘图标了。

『第
2 楼』:
还有c++的一个方法：找出该图标所对应的进程ID，如果该ID为NULL则删除该图标.
下面是源代码（代码引用自网上，作了些修改）：
#include <AFX.H>
#include <COMMCTRL.H>
#include <iostream.h>
int main()
{
HWND hStatus=::FindWindow("Shell_TrayWnd",NULL); //得到任务栏句柄
if (hStatus==NULL)
{
cout<<"Get Shell_TrayWnd error!\n";
return -1;
}
HWND hNotify=FindWindowEx(hStatus,NULL,"TrayNotifyWnd",NULL); //右下角区域
if (hNotify==NULL)
{
cout<<"Get TrayNotifyWnd error!\n";
return -1;
}
HWND hNotify1=FindWindowEx(hNotify,NULL,"SysPager",NULL);
if (hNotify==NULL)
{
cout<<"Get SysPager error!\n";
return -1;
}
HWND hNotify1_0=FindWindowEx(hNotify1,NULL,"ToolBarWindow32",NULL);//右下角区域(不包括时间)
if (hNotify1_0==NULL)
{
cout<<"Get ToolBarWindow32 error!\n";
return -1;
}
//-------------------以上是得到任务栏右下脚一块地方的句柄
DWORD pid = 0;
GetWindowThreadProcessId(hNotify1_0,&pid);
if (pid==NULL)
{
cout<<"Get pid error!\n";
return -1;
}
HANDLE hProcess=OpenProcess(PROCESS_QUERY_INFORMATION|PROCESS_ALL_ACCESS,true,pid);
if (hProcess==NULL)
{
cout<<"Get hd error!\n";
return -1;
}
::SendMessage(hNotify1_0,WM_PAINT ,NULL,NULL);
CRect rect;
::GetWindowRect(hNotify1_0,&rect);
::InvalidateRect(hNotify1_0,&rect,false);
int iNum=::SendMessage(hNotify1_0,TB_BUTTONCOUNT ,NULL,NULL); //获取任务栏上图标个数
unsigned long n = 0;
TBBUTTON *pButton = new TBBUTTON;
CString strInfo = _T("");
wchar_t name[256] = {0};
TBBUTTON BButton;
unsigned long whd,proid;
CString x;
for(int i=0; i<iNum; i++)
{
::SendMessage(hNotify1_0,TB_GETBUTTON,i,(LPARAM)(&BButton));
ReadProcessMemory(hProcess,&BButton,pButton,sizeof(TBBUTTON),&n);
if (pButton->iString != 0xffffffff)
{
try
{
ReadProcessMemory(hProcess,(void *)pButton->iString,name,255,&n);
}
catch(...)
{
}
strInfo.Format("%d : %s\n",i+1,CString(name));
TRACE(strInfo);
cout<<strInfo<<endl;
}
try
{
whd=0;
ReadProcessMemory(hProcess,(void *)pButton->dwData,&whd,4,&n);
}
catch(...)
{
}
proid=NULL;
GetWindowThreadProcessId((HWND)whd,&proid);
if(proid==NULL)
::SendMessage(hNotify1_0,TB_DELETEBUTTON,i,0);
}
delete pButton;
return 0;
}
