如果Resume不能唤起线程,请试试如下的函数,试试。
GetExitCodeThread(ThreadHandle,ExitCode)
来取得ExitCode,如果ExitCode=STILL_ACTIVE
表示线程还存在,对于存在的线程,则可以使用ResumeThread(ThreadHandle)来唤醒线程,如果线程仍然处于运行状态,则会返回错误具体的自己去看相关的API的返回值。
本人在实际应用中还是没能够解决上面问题,只好委曲找到另一种解决方法。
procedure TfrmDataExchangePlatformMain.ActionStartServiceExecute(
Sender: TObject);
begin
StatusBar1.Panels[1].Text := '当前操作: ' + ActionStartService.Caption;
Screen.Cursor := crHourGlass;
try
FExecfinish := True;
Timer_Service.Enabled := True;
//MyThread.Resume;
finally
Screen.Cursor := crDefault;
end;
end;
{
procedure TfrmDataExchangePlatformMain.Timer_ServiceTimer(Sender: TObject);
var
ExitCode: DWORD;
begin
//if MyThread.MyThreadExecfinish then
//MyThread.Execute;
MyThread.Resume;
GetExitCodeThread(MyThread.Handle,ExitCode);
if not MyThread.Suspended then
begin
ShowMessage('可以运行');
end;
if ExitCode=STILL_ACTIVE then
begin
ShowMessage('可以运行');
end;
end;
}
procedure TfrmDataExchangePlatformMain.Timer_ServiceTimer(Sender: TObject);
begin
MyThread := TMyThread.CreateEx(False);
MyThread.ExeTimer := Timer_Service;
MyThread.MemoLogStrings := cxMemo_Log.Lines;
MyThread.LogStrings := cxMemo_Log.Lines;;
MyThread.MyThreadExecfinish := True;
MyThread.HTTPRIOLeExp := DMConn.HTTPRIOLeExp;
MyThread.HTTPRIONC := DMConn.HTTPRIONC;
end;
{ TMyThread }
procedure TMyThread.Execute;
begin
inherited;
FreeOnTerminate := True; {这可以让线程执行完毕后随即释放}
if MyThreadExecfinish then
ExecTimer;
end;
function TMyThread.ExecTimer: Boolean;
begin
Result := False ;
FMyThreadExecfinish := False;
Screen.Cursor := crHourGlass;
CoInitialize(nil);
try
FExeTimer.Enabled := False;
TranspondClientBaseData_factory1(HTTPRIOLeExp, HTTPRIONC, LogStrings);
Sleep(1000);
TranspondPersonBaseData_factory1(HTTPRIOLeExp, HTTPRIONC, LogStrings);
Sleep(1000);
TranspondDeptBaseData_factory1(HTTPRIOLeExp, HTTPRIONC, LogStrings);
//readLogStrings;
//SaveLogFile;
finally
Result := True;
FMyThreadExecfinish := True;
CoUninitialize;
FExeTimer.Enabled := True;
Screen.Cursor := crDefault;
//Suspended := True;
end;
end;
遇到此问题的,不妨这么试试吧, 其实上面找到了原因,但是找不到解决方法, 上面应该是线程被停止了,不存在了, 但是就是不知道在哪被停止的, 因为执行两次resume的时候 exitcode和STILL_ACTIVE还是一样, 但是就是在以后就为0了, 不知道怎么回事。不找原因啦, 就用上面这个方法啦。 如果明白的,请告知小弟,嘿嘿。
