Change default batch script .bat to open with cmd a non extencion file

Actually just booted up a machine to look, assoc is built in command but principal is the same... what I have put above should work OK to launch notepad and the like but if you want it to run as a batch file use either
batfile or cmdfile instead of txtfile... except on mine I then get "xxx.a is not a valid Win32 application" and "access is denied".

So not sure

Steve

It didnt work either with my tests, i get is not a valid Win32 too..

I tryed using the batch script:

assoc .=batfile

When i run that script it associates the icon for a batch script, so i need to solve this two things:

First i need to the batch script with non extension work and not getting is not a valid Win32.

Then i need to make the new batch scripts with no extensions to have the default non associated files icon.

OK.... how about

assoc .=mycmdfile
ftype mycmdfile=cmd /c "copy %1 x.cmd & call x.cmd"
set pathext=.;%pathext%

to remove
assoc .=
ftype mycmdfile=
set pathext=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH

Steve

Odd. Had that working once then it didn't.... FAR too late now will think again tomorrow if t0t0 hasn't been along and nicke thepoints :-)

Hello dragon-it could you find out how this could be done?

Help!! Anyone?

Hello, is the question or what i need to do clear enough? or should i change it for something easyer to understand?

Sorry, I don't know whether that is possible or not off hand and haven't got time for EE questions right now due to a new baby.  Please click on the "request attention" link and it will trigger alerts to other experts.

Steve

I have done that a couple of times but i didnt get a respond, thanks!, and congratulations for your new baby.

ok, and thanks.  I'll ask a few of the other experts here see if they know any more.... what I did above seemed to work when it was an '.XXX' file or whatever but for a non extension it doesn't.   Will experiment when I have time and see if I can rouse some more help.

Not possible.

You can tell by the GUI when you right click a file with no extension and select Open - the option to Always use the selected program is unavailable to select.

Is there any reason why you can't simply add a file extension to your file?

Thats what I thought originally ... though adding it to the pathext variable seems to make it open into IE as a text file for me oddly.

and doing

assoc .x=mycmdfile
ftype mycmdfile=cmd /c "copy %1 x.cmd & call x.cmd"

works for other extensions such as .x above but for . doesn't..

Steve

Netman66 i need to hide as much as possible the source code for some scripts.

dragon-it

The .x scripts open has a cmd window but they dont work, if this cant be donde without  file extencions setting one is better than nothing.. So we can try with .xxx extencions.

If someone knows how to do it without one ill try again.

assoc .x=mycmdfile

you need the pathext variable set too I think to say this is an executable - can you explain how you want this to work again, I.e. are we talking that you want a .xxx extension on someones desktop to click say...

How will that stop them looking/knowing it is a script if you expect them to run it?

You could always have a script that copies a script from a network location that is 'hidden', runs it and deletes or similar etc. though if the user has the rights to run/copy it then they can read it too.

Maybe you need to write this in VB or C and compile into an exe, or I think there are some batch compilers too?

Steve

Yes i have batch compilers but it can be easyly get the source scripts, i need to go as further that i can, i have a couple ideas i worked on, this scripts with no extencions are really for the temp folder maybe they wont notice it is a batch script and will not run on other computers if they are extracted and i am making them to work automaticly they wont be for the user to open them, i hope you get the idea. I cannot use VB or C because i dont know the language.

If you can do the batch script with real code at least for .xxx i can understand it and edit it to what ever i want i hope you can help with it.

Can you not just encode them?

http://www.wikihow.com/Encode-a-Computer-File-Into-a-Base64-Encoded-Text-File

Ill try it again myself later from a clean machine but the code I posted before should work from the cmd.exe window you are in.  Otherwise the pathext variable may need changing globally from control panel, user environment in system.

Anyone savvy enough to look in the temp folder would probably be capable of spotting an odd file like this but I imagine in terms of usefulness:

1. Mark the file hidden and/or system - explorer will hide these unless someone has unhidden such files in the options (i.e. a techie).

If they are temporary batch files could they not be deleted at the end of the script with a DEL command?

How are they created, and what sort of things are they doing I.e. does another script run them or the user from an icon (in which case they could right click and open with notepad anyway).

If they are running from another script then hide the files with attrib command, rename .cmd to .tmp or something and when your other script comes to run it rename .tmp to .cmd etc..

Sorry for all the 'it depends'!

Netman66 is there  way to run the encoded file without deconding it? as a batch script, a b64, exe or any other file? or can it be converted it to exe, batch, vbs when encoded and run it like that?.

dragon-it can i add the path ext globally variable from a batch script or reg file?

The temporary batch files can be deleted but while installing they can be extracted, some program take too long with the script open because they take a long time to install.

There is a compiled main script that extracts the temp batch script and that script calls other scripts and programs, but the rest of the scripts are batch scripts.

I already use the renaming but there is a time window when the script is exposed and i need to do this the safest way i can. The base64 its a good idea if it could be run encripted or encoded.

The non extension / or other extension runing as a batch script its a great idea because they  extract the file they wont work on other computers, so if that could be done its a little better than what i have right now. Anyone knows how what can be made?

An encoded file runs as it normally would.

But i have to convert it back decoding it to a batch script? or it runs just like a batch script?, because i cant open it when its encoded.

Or how can i do to run it encoded, just if like it where a batch script?

What happens if you leave the extension as a .CMD or .BAT?

VBScript can be encoded and saved as a .VBE using SRCENC then run normally.

I need to have the source code encripted, that cannot be taken or viewed but still have to run the scripts.

This SRCENC converts only  vbs scipts to vbe? i really dont understand vbs.

Could this work on batch script files?, i understand them much better, i took a look on SRCENC but didnt understand what kind of files or how to manage them.

The base64 scripts are great only if i could run them encoded, and if they would work just like a batch script.

Any other ideas on how i can do this, if they get the files but they cant run them on other computers without the programs or asosiating a non extension file, lets say its a batch script with .tmp extension, if they get that file they wont be able to run on other computers.

Does exist a visual studio, c#, delphi or other small compiler that i can convert the .bat scripts to .exe but that dont leave .bat files hidden on temp folder with the source code?.

Im getting a error message the system cant find the specified file when running newbatch.y

I think its x.cmd that is causing the error on temp folder.

When its running fine how would i change de extension? only the .y to new extension .new?

assoc .y=mycmdfile to assoc .new=mycmdfile

Does x.cmd carries the original batch script code?

Correct.  Yes it still has to rename it to .cmd to run it... (which I know defeats the object a bit!)
Steve

Hey dragon-it did the last script worked well for you?

Maybe can this be done programed on other any language to make it and undo, and then i can call them when the script starts and when the script ends.

Anyone can do it?

Did you try the BAT-to-EXE convertor above?

Yes, i have tryed most of those programs, it looks like thisone its working the online compiler didnt work i didnt know if it was the program or the online one that left the source on temp folder, im just making my tests but im also trying to make what i originally want to do.

Yes the assoc and ftype worked for me (just typing those at .cmd prompt then you can do start | run something.x or type something.x from cmd.exe prompt BUT it does leave the script in tmp as a .cmd....
