Can someone convert this batch file into a vbs please?

Here is a batch file I made, so that I can run Minecraft on a computer where I don't have access to the real %Appdata%, so it makes Minecraft think that Appdata is at N:\data !

Code:

@echo off
SET APPDATA=N:\data\
Start  "Minecraft" "N:\minecraft.jar"

Now, the problem is- on this system we are not allowed to use the command prompt AT ALL.

So batch files won't work.

However, we CAN use vbs files.

I was wondering if any of you incredibly nice people ( ) could convert this basic batch file into a vbs that will do exactly the same thing.

Thanks in advance.

 

Try something like that:

Code:

Set objWSH = CreateObject("WScript.Shell")
objWSH.Environment("PROCESS")("APPDATA") = "N:\data"
objWSH.Run "N:\minecraft.jar"

Thank you!

I will test this tomorrow.

 

You should also test this 3rd line:

Code:

objWSH.Run """Minecraft"" ""N:\minecraft.jar"""

because I'm not sure about the meaning of "Minecraft" in your batch file (looks like wrong syntax).

It's irrelevant really, it just gives a name to what I'm running "Minecraft".

 

I feared there would be a minecraft.exe in the current directory.
But now I assume the START line of your batch file has the right syntax, also my first code should work as provided.

Hi it's me again.

It worked perfectly (thanks), but I'd like to give it 2048 MB of RAM.

The Minecraft website says to run it as "java -Xmx2048M -Xms2048M -cp Minecraft.jar", but I don't know how to do this in vbs...

 

Depends on where java.exe ist placed on your drive.
Try:

Code:

Set objWSH = CreateObject("WScript.Shell")
objWSH.Environment("PROCESS")("APPDATA") = "N:\data"
objWSH.Run """C:\Program Files\Java\jre6\bin\java.exe"" -Xmx2048M -Xms2048M -cp N:\minecraft.jar"

But if you have another java version the path could also be different.

The java.exe is placed there (I checked), but this script does nothing.

It brings up the command prompt for like 1 millisecond, and then nothing happens...

 

I'm not familiar with this computer game stuff. I had a look at my registry to figure out how .jar files are opened by default. For that reason you should try the following line

Code:

objWSH.Run """C:\Program Files\Java\jre6\bin\javaw.exe"" -Xmx2048M -Xms2048M -jar N:\minecraft.jar"

Now also a message box should turn up if an error occures.

Now I get "cannot create the virtual machine...".

But at least I got something there, lol.

 

Did you use option -cp or option -jar ?

 

-jar

 

Seems you try to allocate too much RAM space. As far as I know the limit on 32bit systems is 1536 MB (not sure).

That was the problem!

Thank you again

 

Happy to help you
