在没有用户许可的情况下终止进程不是好的做法,相反,您必须询问用户是否要终止应用程序(在这种情况下是 Web 浏览器)。
现在回到您的问题,您可以使用该方法检测应用程序(网络浏览器)是否正在运行检查进程名称(firefox.exe、chrome.exe、safari.exe)CreateToolhelp32Snapshot
。
uses
Windows,
tlhelp32,
SysUtils;
function IsProcessRunning(const ListProcess: Array of string): boolean;
var
hSnapshot : THandle;
lppe : TProcessEntry32;
I : Integer;
begin
result:=false;
hSnapshot := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if hSnapshot <> INVALID_HANDLE_VALUE then
try
lppe.dwSize := SizeOf(lppe);
if Process32First(hSnapshot, lppe) then
repeat
for I := Low(ListProcess) to High(ListProcess) do
if SameText(lppe.szExeFile, ListProcess[i]) then
Exit(True);
until not Process32Next(hSnapshot, lppe);
finally
CloseHandle(hSnapshot);
end;
end;
并像这样使用
IsProcessRunning(['firefox.exe','chrome.exe','safari.exe'])
现在如果你想要一个更可靠的方法你可以搜索窗口的类名(使用FindWindowEx
方法),然后是句柄的进程所有者的PID(使用GetWindowThreadProcessId
),从这里你可以使用进程的PID来解析exe的名称。
{$APPTYPE CONSOLE}

var

hSnapshot := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
if hSnapshot <> INVALID_HANDLE_VALUE then
try
lppe.dwSize := SizeOf(lppe);
if Process32First(hSnapshot, lppe) then
repeat
if lppe.th32ProcessID=th32ProcessID then
Exit(lppe.szExeFile);
until not Process32Next(hSnapshot, lppe);
finally
CloseHandle(hSnapshot);
end;
end;
