如何从批处理文件运行Visual Studio exe

Question

My script is as below:

for %%i in (*.mudp) do echo %%i >> test.txt
@ECHO OFF
SETLOCAL
:: remove variables starting $
FOR  /F "delims==" %%i In ('set $ 2^>Nul') DO SET "%%i="

FOR /f "delims=" %%i IN (test.txt) DO SET $%%i=Y
(FOR  /F "delims=$=" %%i In ('set $ 2^>Nul') DO ECHO %%i)>test.txt

 for /f %%C in ('Find /V /C "" ^< test.txt') do set Count=%%C
  echo The file has %Count% lines.
@echo off
cd "C:\Users\gbyraiah\pcap\createPcap\Debug"
start createPcap.exe %Count% 
exit

I am listing all text files with .mudp extension in the current directory to a test.txt file in Windows.

Then counting the number of files in the list and so I get Count value of 2 if 2 .mudp files are found.

Then I want to open Visual Studio .exe , loop the .exe to run it the number of times equal to Count and also pass count as a command line argument to the exe.

So here my issue is I am not able to run the .exe and so neither I am able to loop.

Answer 1

Simply write yourExecutable.exe to start it; write yourExecutable.exe 1 to pass over the argument 1 .

To do that in a loop using arguments from 1 up to the value of %Count% , do this:

for /L %%J in (1,1,%Count%) do yourExecutable.exe %%J

The start command should not be necessary for running your .exe at all. Regard that start runs the .exe in a new process, so the batch script does not wait for the .exe to be finished, unless you provide the switch /WAIT (like start "" /WAIT yourExecutable.exe ; "" is the title of a new window that might be opened, which should always be specified to avoid trouble with quotation of paths).
