These scripts are called by other processes, and are ran on a server, so there is nobody to dismiss the error box. What I'd like is for the error message to be dumped to STDOUT, and execution to return the calling process. Popping as a MSGBox just hangs the entire thing.

At the Windows command prompt, type the following to display help. cscript //? I suggest the following: cscript //H:CScript This will make CScript your default scripting interpreter. CScript prints messages to the console (i.e., stdout) as you desire. (It does not use dialog windows.) You may also want to try the //B switch, but I can't tell if that has to be run per-script or not. If it is a persistent, one-time switch like the //H switch is, then this may work for you; if not, you may need to modify all of your remote programs to include it. From the information you provided, I think just changing the default interpreter (//H) will do what you want. You will also need to add some sort of error handling to keep the script from terminating on an error. In Visual Basic Scripting Edition, the easiest thing

Good error handling is https://redmondmag.com/Articles/2000/05/01/Graceful-Error-Handling.aspx the key. Graceful Error Handling Sometimes, you want to trap scripting errors before anyone notices. Good error handling is the key. By Chris Brooke05/01/2000 I remember a certain math http://www.robvanderwoude.com/vbstech_debugging.php teacher I had in high school. She was so understanding. Whenever I made a mistake on my homework, she would lean all 275 pounds on my desk, put those on error big, bloodshot eyes right in front of mine, and say: “You Got It WRONG!” Ever since then, I’ve tried to ensure that if I do make a mistake, I fix it before anyone else notices. As NT administrators, we must remain vigilant about errors. We perform backups, install hardware RAID 5 arrays in our mission-critical servers, and on error resume even implement expensive single-IP clustering solutions to make sure that if—heaven forbid—anything does go wrong, no one will notice (we hope). It’s important to be equally conscientious regarding potential errors in your scripts. Exactly how idiot-proof we can make our scripts depends on the particular idiot (ourselves) running them. (I’ve always maintained that as soon as you make something idiot-proof, someone comes along and builds a better idiot!) As scripts become more complex, the potential for errors increases greatly. It’s vital to trap these errors as they happen and deal with them gracefully. The alternative is the see-no-evil, hear-no-evil approach—close your eyes, wait for something to happen, and then blame the user! To Err is Human, to Forgive… Err.Clear There are several ways to handle errors in your scripts. For instance, in “Supercharge Your Scripts” (October 1999), I put an “If…Then” section at the beginning of the script to ensure that the user had entered the correct command-line arguments. That’s error handling! That kind of error handling is preventative; whereas, here
