窗口服务无法触发exe [英] Window services cant trigger exe

问题描述

我在c＃

中创建一个窗口服务以在特定时间运行exe。但是它可以打开那个exe，

下面是代码

  private   static   string  checkdatentime（）
 {
 currentdate = DateTime.Now; 
  string   value  =   1; 
  for （ int  i =  0 ; i <  xml_date.Count; i ++）
 {
  value  =   2; 
  if （currentdate.Date <  xml_date [i] .Date）
 {
  value  =   3; 
  break ; 
  //  一边走一圈;  
 
} 
  else   if （currentdate.Date >  xml_date [i] .Date）
 {
  value  =   4; 
  //  不执行任何操作意味着循环继续 
 
} 
  else  
 {
  value  =   5; 
  //  如果两个日期相同 
 
  if （currentdate.Date == xml_date [i] .Date）
 {
  value  =   99; 
 currentTime = currentdate.ToString（  hh：mm）; 
 TriggerTime = newItem.TriggerTime.ToString（  hh：mm）; 
 
  if （currentTime == TriggerTime）
 {
  value  =   6; 
  //  运行EXE  
 System.Diagnostics.Process.Start（  E：\\SqlBackup_Programs \\console-backup \\Backup_Console_App 22July Latest\\Backup_Console_App\\ \\\Backup_Console_App\\bin\\Debug\\Backup_Console_App）; 
  return   value ; 
} 
 
} 
 
 
} 
 
 
} 
 
  return   value ; 
} 
 

注意：这里我返回值因为验证是我的代码运行正确与否，并在文本文件上写入VALUE，所以同时我得到VALUE = 6，意味着代码没有问题，

但仍然服务无法打开这个exe，

通过相同的代码我制作了控制台应用程序并且它的运行完美，所以为什么不运行？



这是命令的任何问题，

 System.Diagnostics.Process.Start（）; 

请帮助我!!

解决方案

Windows服务无法使用用户界面运行/启动进程。没有办法解决这个问题，这是设计的。

我得到了答案，我检查了选项Windows服务属性中的允许与桌面交互现在它正在工作。 ： - ）

I make one window service in c#
to run exe on particular time., but it could open that exe,
Below is code

private static string   checkdatentime()
       {
           currentdate = DateTime.Now;
           string value = "1";
           for (int i = 0; i < xml_date.Count; i++)
           {
               value = "2";
               if (currentdate.Date < xml_date[i].Date)
               {
                   value = "3";
                   break;
                   // go out side for loop;

               }
               else if (currentdate.Date > xml_date[i].Date)
               {
                   value = "4";
                   //Do nothing means loops continues

               }
               else
               {
                   value = "5";
                   //if both date are same

                   if (currentdate.Date == xml_date[i].Date)
                   {
                       value = "99";
                       currentTime = currentdate.ToString("hh:mm");
                       TriggerTime = newItem.TriggerTime.ToString("hh:mm");

                       if (currentTime == TriggerTime)
                          {
                              value = "6";
                           //Run EXE
                              System.Diagnostics.Process.Start("E:\\SqlBackup_Programs\\console-backup\\Backup_Console_App 22July Latest\\Backup_Console_App\\Backup_Console_App\\bin\\Debug\\Backup_Console_App");
                           return value;
                        }

                   }


               }


           }

           return value;
       }

NOTE: here I return value because to verify is my code runs correct or not and write VALUE on text file, so on same time I am getting VALUE=6, means there is no problem in code,
But still service cant open this exe,
by same code i made console application and its runs perfectly, so why not services??

Is this any problem with command,

System.Diagnostics.Process.Start();

kindly help me!!

解决方案

A Windows service just cannot run/start a process with a user interface. There is no way to solve this, it's by design.

I got the answer, I had checked the option "Allow to interact with the Desktop" in the Windows service properties And now its Working. :-)
