So I am in a computer class and we are learning about scripts. During this class I asked my instructor if there was any way to basically plug in a usb thumb drive into a pc and automatically complete these following steps:
Open a specific applications file location
Copy said application
Paste said application onto the desktop
rename said application to the desired name
So yeah, was wondering if anyone could help me out or show me how to do this and such, I am quite new to all of this.
I haven't really tested that much, This is the first forum page I thought of coming too since my peers have had some good results with help from other users.

I have a bluetooth enabled CNC(key cutter) that I control it from my phone via an app(ios but an equivalent is available for android). I need to be able to gain access to the machine directly with bluetooth or usb(already tried on pc) so I can try to find the correct memory offsets and values so I can change precoded names, values, for already existing "cutting profiles"(Not sure if these files are in the CNC or the app).
Trying to reverse engineer the app seems like a waste of time until I can at LEAST discern which files to expect are kept on the cnc, and which files are kept within the app.
I have experience with memory editors such as cheat engine, a little C / C++.
I have tried searching for solutions based in Bluetooth, but that is only getting be basic file transfer explanations. The app gives no direct access to files of any kind.
ANY help pointing me in the right direction for where to start with this problem, or reference material you think would be relevant would be helpful.
I am a self-taught programmer and have only delved into new areas of programming as the need arises. I have never done any network programming, everything I have written has been for a single computer. I have written a program for an old board game and it runs great. But, now I want to try to write it to run for multiple players across a local network. I have an idea of what has happen in terms of constantly checking a specified folder/file for changes. But... how do you test this without actually building/compiling the program and installing it on another computer every time you make any changes? I have tried to search various forms of what I have as the title here, but all that comes up is about testing network connections, or socket programming (would this be easier/needed) or systemfilewatcher (which may be an option too if it will run on Windows 7 and 10... but, I find nothing about testing programs to actually access the network and simulating 2 copies of the program running. Any suggestions, links, etc. would be greatly appreciated.
I think you will be disappointed in the performance of a file-based network game unless reaction or refresh time is of little consequence for your "board" game. You may also need to work out potential concurrency issues (ie, someone updating a file you've just read). If you have any desire to do other games in the future you should be using sockets (most likely UDP unless you have a good reason not to) to create a client server system.
As to your question, yes, you should be able to test it. You just need to run both a compiled exe and the source in VS debug mode, accessing the same folder on your drive. If you go with the socket-based option, you would use your PC's loopback address 127.0.0.1 (sometimes known as localhost), but the 2 different parts will need to communicate on different ports.
I'm an experienced software engineer in the telecomm industry, lately I've been interested in working on a hardware project.
One of the ideas that floated around in my head is the concept of an open source tablet computer. I'm inspired by the success that the Arduino has made, and it is my personal belief that if this device was open source it could be a great platform for inspiring new projects, and become a cheap device for schools!
Can any of you give me suggestions where an idea like this has been tried before, what went right, and what went wrong?
Well I agree with Casio (this is probably not the place to ask such a question: not sure what is, though), but a significant effort with something similar was made as a part of the OLPC project: it is as open as you could hope, low cost...I would say that is as good a starting point as any: replace the screen with a touch screen and hack away!
On the other hand, there's a company selling kits for basically exactly what you described. Let us know if you go anywhere with this...I'd like to know. :)
Check out the Open Compute Project which started back in 2011 building vanity free open source hardware (servers) for data centres.

I'm trying to run a program written by someone else in LabVIEW. The program records voltage. However it won't open because it is missing subVIs.
Initially I thought that only one was missing and the rest weren't working becuase they were attached to it but after someone on this forum kindly found it for me the rest of the VIs still won't work so I think I need to download them again. However there are too many off them to get separately, also I tried googling them to no avail.
The subVIs are : Magnet Id, Hardware check, Plot Data and Print, Make Plot Lables, Plot it, Relabel It, Write File header, Record Analog Info, Fix Column Heading, Make Igor Label etc etc (this is not a complete list).
I feel that I should download a DAQ from The National Instruments Website but I am not sure which one. I am using 64 bit LabVIEW 2010 on Windows. Can someone please help me pick out the correct driver?
Thanks!
Just going from memory, those aren't NI VIs that I recognize, especially if the misspellings are in the original.
What hardware is this interfacing with?
You should still be able to open the main VI. It will not compile or run, since the subVIs are missing, but you should be able to open it and maybe get some clues about what it's doing.
The SubVIs all appear to be in the llb file so they should be available. I'm not sure how you can access the subVIs directly from the llb file so you may want to convert this to a project folder (this is the new way of creating libraries since version 8 I think). There are some pages on the NI website that may help, try Converting an LLB to a Project Library and then add this Project Library to your project.
From what I can see the VIs make use of the VISA drivers to communicate with the individual instruments so you should make sure you have this installed. You don't mention what version of LabVIEW 2010 you have but I think they should be provided even the Basic version, I know they are provided with the Professional Development System version.
I am using an Olimex sam7s256 board. I tried to get it up and running in linux (Ubuntu). I was able to successfully install GCC and binutils. I installed SAM-BA for linux from the atmel site. I was able to get the USB port for connection as specified in the SAM-BA manual (.dev/ttyUSB0).
But when I try to use the GUI and 'connect' there is no response.
I though that there is a connection failure, so when I presses the reset button in the board, I get a message "Failed to initialize FLASH accesses".
No matter how long I wait before pressing the reset button, I am not getting any SAM-BA window as given by other tutorials as below
can any one one help me out in this?
I did the 'tst' jumper set, reconnect the board for 10 s, disconnect and 'tst' jumper reset, reconnect before opening SAM-BA.
Any help will be greatly appreciated.
I am stuck.
It is the same for both SAM-BA 2.9 and 2.8.
By this point you are already connected. If you specified the at91sam7256-ek even if you arent using that board it will not put this gui up if it didnt talk to the chip/board. I recently went through this exercise with an olimex sam7s-256 header board. (with ubuntu linux). If I didnt specify the board type then the window came up but it wasnt really connected.
Notice how the code at 0x00200000 is valid instructions (most start with a 0xE and the vector table starts with a bunch of 0xEAs which are branches out of the vector table) that is ram it didnt make those up it read that from somewhere. Load a binary file into ram in the 0x00200000 range and the refresh the memory (assuming your binary is different from what is there) and see it change.
When ready/comfortable you can erase the flash and see in the memory window that the flash (0x0010000 or something like that) changes to all 0xFFFFFFFFs. Now remember it wont boot when you do that. With the board I have there is a jumper you move then power the board to get the built in bootloader re-loaded into the flash so that you can use sam-ba again, I am sure there is a way to do that with your board but read the users guide first.
Please do not close this person out for asking about using a software tool. There are countless numbers of how do I use my iphone simulator or why is my android simulator slower than my iphone simulator questions that dont get touched. this question is as relevant as any of the programming questions about how to use gcc or some web thing or how to start up my phone simulator or java vm. I wouldnt want to have to start a campaign to close all of the gcc or iphone tagged questions because they are not programming questions.
I think my question was misunderstood. The GUI window which I have posted is NOT what I get. I just posted it to say that I am not getting such a window at all. That window pops up only when I select 'no board'. When I select SAM7S256-EK there is no response. No window opens. As given in your blog sam7stuff.blogspot.com, I downloaded SAM-BA. The onlydifference as u have posted and in the response also id that u are using a 'h' board.
Right now I am using a custom made SAMBA alternative from this website,
http://claymore.engineer.gvsu.edu/~steriana/Software/
It is also a python based boot loader. It is command line though.
I would love to use the SAM-BA GUI. I am sure that the board is OK and samba is communicating with the board b'cos if I select any other board type other than ARM7S256-EK option it is giving me 'communication failure'.
If you have any suggestions please do let me know. Also many thanks for backing me up. I had some real good insights from this forum about embedded field and I felt it is a good place to discuss embedded programming doubts and never thought of 'programming' or 'non-programming' b'cos for SAM-BA user guide itself talks a lot about customizing the SAM-BA for a custom made board involving TCL scripts but I couldnot get hold of the concepts. So I thought someone would have had the same problem and would have found a TCL or C 'programming' solutions in this forum.
Thank you.
