In the case your batch ends with a CLS command typically added to ensure the command interpreter's window gets closed or with an ECHO command to send some final message to the console, the command will very likely succeed is there any way to make such commands crash?
If you want to retrieve some value produced within the batch such as a command's error code , your best bet is to send it to some output channel and have a stream to catch that channel from your Process instance I can get into deeper detail about this if you can confirm this is what you need.
Also, keep in mind that normally running a batch means something like "invoke CMD. EXE the command line interpreter will likely succeed even if its success is just complaining about some issue with the batch file , it will return zero as its error code. This may be interfering with how Exitcode is retrieved. With so few details, that's all the advise I can give.
Hope this helps. Regards, Herenvardo. Honestly, if running a valid batch file through the Process class yielded a non-zero ExitCode, then I'd begin to worry. You know that when you try to start a. If you take a look on Windows task manager, you'll see that the process running from that action is winword. Batches ain't different: just like. So your process isn't really the batch file, but the CMD.
EXE that's invoked to interpret your batch file. As long as your batch file has reasonable contents, CMD will succeed at parsing and processing it if one or more of the commands on the batch fail that's a separate story , so CMD's exit code should be 0 to represent such success.
In other words, the fact that CMD stays between you and the batch file means that you get CMD's exit code instead of the batch's code. Which in turn means that your need doesn't have an easy solution. So we have to get a bit more creative and look for the possible non-easy solutions. View all page feedback. In this article. Specifies a true condition only if the previous program run by Cmd. Specifies a true condition only if string1 and string2 are the same. You do not need to enclose literal strings in quotation marks.
Forces string comparisons to ignore case. These comparisons are generic, in that if both string1 and string2 are comprised of numeric digits only, the strings are converted to numbers and a numeric comparison is performed.
To know about Environment variable see the below note. Note: Environment variables are a set of dynamic named values that can affect the way, running processes will behave on a computer. For example, an environment variable with a standard name can store the location that a particular computer system uses to store user profile this may vary from one computer system to another. I want to know how they work. Add a comment. Active Oldest Votes. There is a great difference in using the if errorlevel or retrieving the value in the variable: The variable read operation will check if the environment block contains a variable with the indicated name.
The if constuct will not make this test. The variables The batch syntax does not include the option of having more than one variable pointing to the same value in memory in a way that if one of the variables changes its value, the other will reflect the change. See next line line 4: the current delayed expansion used value of the errorlevel variable is retrieved and stored in exeErrorlevel variable. Improve this answer. Community Bot 1 1 1 silver badge. Thank you for your links.
I've updated the question with my code and am realising maybe I don't understand delayed variable expansion properly. Thank you for clarifying that set does not store a pointer, but a copy.
I thought that waiting for them would be silly. Also, I noticed that often! I will implement your suggestions, but what does the "" do before the start command? Sign up or log in Sign up using Google. Sign up using Facebook.
