Waiting for files to finish after folder loop

Brian Nowlan

I have a programme where files in a folder need to be launched sequentially. I am using the following Process[] localByName = Process.GetProcessesByName("iOSRVEODMAIN") Once the first file is finished it’s process I need it to move onto the next file. I can’t seem to figure out how to use the folder foreach and the Proccess wait for exit loop as each file will need a wait for exit of Process[] localByName = Process.GetProcessesByName("iOSRVEODMAIN")

I'm not quite sure about its execution (as not having vbs files), trying below snippet will help you to accomplish it.
string filepath = "c:\\Patch_DevSSO\\";
            DirectoryInfo d = new DirectoryInfo(filepath);
            DirectoryInfo info = new DirectoryInfo(filepath);
            string.Format("\"{0}\"", info.FullName);


            foreach (var file in d.GetFiles("*.vbs"))
            {
                string commandArg = string.Format("\"{0}\"", file.FullName);

                var myProcess2 = new Process { StartInfo = new ProcessStartInfo(commandArg) };
                myProcess2.Start();
                Thread.Sleep(500); // sleep the process for 500 millisecond, so that it can capture the process if started delayed

                //Each vb starts the process
                Process[] localByName = Process.GetProcessesByName("iOSRVEODMAIN");
                foreach (var process in localByName)
                {
                    //waiting for exit
                    process.WaitForExit();
                }
                // waiting for exit of the main process
                myProcess2.WaitForExit();

            }
            Console.ReadLine();

Each Vb file in the folder launches an instances of iOSRVEODMAIN.exe
The VB file is ran by the foreach looping through the folder. currently it runs each file sequentially.which is fine.
I am looking for it to wait for iOSRVEODMAIN.exe to finish its task based on the particular VB script which can take a variable amount of time..
File1.vbs launches with instances of iOSRVEODMAIN.exe WaifForexit then launch next file in folder
File2.vbs launches with instances of iOSRVEODMAIN.exe WaifForexit then launch next file in folder

I hope this explains it ok it's a bit confusing

Ah!! Let me rectify my improper snippet, I read your question in a hurry!
Process[] localByName = Process.GetProcessesByName("iOSRVEODMAIN");

            foreach (var process in localByName)
            {
                process.WaitForExit();
            }
The above code will get the process name and wait for exit and continue execution for further line to process.
The code was good, will you elaborate, what exact problem you are facing

Apologies for the code as I am just trying to understand it all a bit better.
myProcess2.WaitForExit(); //apply wait for exit here, so that your loop
This willl not work as I need the specific name of the EXE highlighted Process.GetProcessesByName("iOSRVEODMAIN"); This is a VB shell which the VB script launches at each file

Hey @Brian
The below code was poorly written here, as this will decrease the performance.
foreach (var process in localByName)
            {

                process.WaitForExit(); // it is useless here, will not work!


            }
You can wait for the process for its exit until the process is being called by your application. like
foreach (var file in d.GetFiles("*.vbs"))
               {
                   string commandArg = string.Format("\"{0}\"", file.FullName);

               var myProcess2 = new Process { StartInfo = new ProcessStartInfo(commandArg) };
               myProcess2.Start();
               myProcess2.WaitForExit();  //apply wait for exit here, so that your loop will wait for the process to exit, you can also pass millisecond on its parameter to wait for that particular time
               Console.WriteLine(commandArg);

               }

Hope it helps :)
