Batch files ?!!!!?

[sarah516]

Hi,

I am using a batch file to silently install an application and then later in the batch file refer to that installed app.

One problem I am facing is that in my batch file:
line#1 creates the app
line#2 refers to a file created by line#1

the PROBLEM is that by the time line#2 is called, line#1 has not completed creating the app, so I get a msg that the file&folder I am looking for does not exist!

Is there any way to make the batch file wait until the entire application is created?  

Also, second question... is it possible to use some sort of condition to:
if(app does not exist)
    create app
else
    just keep going  8-)


Thanks

Hi sarah516;

Look you can do this very easily by simply using a start wait call.
More info: http://www.computerhope.com/starthlp.htm

your command line would thus be something like:

start /wait [command/program]

This ensures that your programs do not trip over each other while trying to complete.

Hope this helps you out.

Depending on how long it takes to install the program, you could try this:

@echo off
(((put your code to install the program)))
PING Insert 7=(8-1) second delay
PING Insert 7=(8-1) second delay
PING Insert 7=(8-1) second delay
(that will delay for maybe around 6 seconds)
(((put the code to refer to the program)))

Basically PING Insert 7=(8-1) second delay puts in a delay between commands.

Hope it helps.

carbon dudeoxide i dont think ur way is really good because if u do that
the file might still be not there so use the "start /wait [command/program]" way
that will ensure that the file would be there

I typed start /wait /? in command prompt and it seems very complicating...just have to know how to use it...

Why are we trying to silently install an application?

edit:
And then run it?

[lordoftheplat]

maybe people want to start a keylogger to log what theif kids are doing or something

. . . or for other, more sinister reasons.
I don't think it is wise to proceed any further before we know what's going on here.

[lordoftheplat]

dont think so negatively

Lol, sarah, what exactly are you trying to do?

I think negatively, then I am pleasantly surprised if I am wrong.
And this does sound fishy to me.

you guys are thinking way too negatively. i work at a computer company and we silently install programs all the time on client computers. the beauty of silent install is that it doesn't bother/confuse the current user with open windows, and also leaves less chance that they'll "accidentally" close a window that's doing something important.

trying to do something unnoticed doesn't mean you're doing something devious.

OK, I guess.
Still, it could be malicious.
Can't be too careful.
