Send commands to the OS

is it possible to make simple java console application which can send commands to the os? for example in linux, if I want to remove a file through my application, can I send the "rm" command somehow?
thanx a lot

However if you just want to remove a file, you might find the delete() method of java.io.File more convenient than wrestling with all the pitfalls of Runtime.exec().

New Win7 install. Can't open html files. Get "there was a problem sending command to the program".

When I try to open an html file on my hard drive, I get a "There was a problem sending the command to the program" error. There is no way I can open a local html file with firefox, even though Win7 sees it these files as Firefox documents. This is a brand-new Gateway tower running Windows7-64, Athlon phenom 4x processor, 6G RAM, and the latest version of Firefox (a week old).

Can't open Excel files saved to desktop, get popup "There was a problem sending command to the program".

Whenever I save an MS Excel file to my desktop, it creates an icon on the screen. But when I try to open it, I get a popup that says "There was a problem sending the command to the program."
This happens with all Excel files - but MS Word and other files work fine.
Thanks for your help.

Yes, I saw that earlier but it seems to be a temporary fix. I had the same issue return 2 weeks ago, then again yesterday. Each time, I've tried this solution which works but only to see it return at some time in the near future.
Coincidently, I have a similar issue occur on my iPhone 4S w/ iOS 6. There, my keyboard shortcuts won't work in forms unless I tick off Data and Documents iCloud setting, power down the phone, then turn it back on. But like this, it only seems to work for a temporary time and the problem resurfaces in a few days.

How to send command to the control board?

Hello everyone
I am developing pci-7344`s driver under RTX.It says in the DDK that
command and data passed to or from the controller is handled in a
packet format. A packet consists of resourceID,commandID,data etc.Now I
know the information of resourceID,commandID,data etc.DDK or the
hardware user manual does not mention how to send them in a packet.
Moreover The command buffer register is 16-bit.
I try to send them one by one but it indicates "modal error" in the
csr.Since I have not programmed "error-handling" part of the driver ,so
I do not know what the error codes are.
Hope some advice on how to send the command packet? It is best if there
is an example !!
Thank you!!!

Sandy,
Here is a modified version of the example I suggested. It includes the option of using the parallel port for communication. I am in the process of getting some example ZPL for you for the label formats that you are using.This example should give you everything you need to communicate with the printer.

The line "@ SEND /A=N" shouldn't serve any function.
SEND "Message" [TO] <user|group|server> [/B] [/A=N]
/B bindery mode (allows some additional options)
/A=N exclude yourself from the broadcast
SEND.exe stems from NetWare 1.x/2.x/3.x/4.x and has been replaced by the
Client32 broadcast functionality.
There are a couple of 3rd party replacements from the command line.

Unable to send command to smart card reader

i am writing code for reading/writing to a smart card through a smart card reader which support RS232 serial communication.
Problem is that the reader is not responding to the commands i send to it.
My Smart CArd reader (HID 6055 Mifare Smart CArd reader) sends some ack when it is switched on. That data i am able to receive though the following code.
So i think i am unable to write (send command ) to the reader.
Also how do i debug my code to see whether the command is actually being sent or not. I tried hyper terminal but if i use hyper terminal then the java prog is not able to open an OtputStream for writing to the smart card.
I appreciate your kind help...

hi all..
Im new to this technology and wanna learn and try to program some simple applications using Smart Card...
Reading thru all the topics above, Im wonderring is the Card Reader able write codes to the Smart Card, or maybe jux simply able to update the info inside the card??
I also heard about Card Decoder as well, I mean if the Card Reader can do the task.. why do we need Card Decoder ?!
Sorry if I stated something wrong... Im new and hope that someone could share some valuable knowledges here...
Thanks much much !!

Possible to start or send commands to an app from a dock button

Hi,
I was looking into the MFi-program, but before that I was interested in if it is theoretically possible to do this:
Start an ipad-app initiated from a dock-button (e.g. Skype) and then send commands to the app depending on other input from the dock? All over Apple Accessory Protocol.
Best regards

Hi vernel,
Welcome to the Support Communities!
First, I recommend restarting your phone and then resetting if it's still not working:
Restarting your device
Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
Press and hold the Sleep/Wake button until the Apple logo appears.
Note: Reset your device only if you are unable to restart it.
Resetting your device
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
Below are the full articles:

How do I send commands to my oscilloscope in NIMAX?

Hello all,
I am new to LabView and have purchased a digital oscilloscope & a digital signal generator.
I have the Remote command list for each of them.
The oscilloscope is USB, and the signal generator only has an RS232 port.
I am able to send commands to the oscilloscope through the EasyScope software that came with the scope, such as *CAL?, which successfully calibrates my scope.
However, I cannot get my scope to respond in NIMAX.   Nor am I able to get the Signal Generator to work in either NIMAX or EasyScope.
Could someone tell me what I need to do to activate my USB channel in NIMAX, and also my RS232 channel?
Solved!
Go to Solution.

These are cheaper devices from ATTEN.   They also go under the name Siglent.   I have an ADS1102CAL+ scope, and a ATF20D+PA signal generator.
I am running 64bit Windows 8.    I am able to get both the scope & COM1 serial port to show up in NIMax and they look good in Device manager.
The Serial cable is a USB to RS232 adapter, since my PC has no serial ports.
The test panel returns a string for the scope serial number using *IDN?, but none of the other commands work.
Here are 3 screenshots. 3rd shot is 2 commands (*IDN? & *CAL? for the USB Scope. )
I have not been able to get the USB drivers to work or install from their website.

GPIB 488.2 Send command

Why is it that when I use the GPIB 488.2 Send command, using the string "ID", it sends the string over and over again? I just want it to send the string once.

The Send command should only send the string once. Could you possibly attach an NI-Spy log or a GPIB Analyzer capture to show us the problem?

When i click on an excel or word file in 2007 the program begins to open but then an error message says There was a problem sending the command to the program

when i click on an excel or word file in 2007 the program begins to open but then an error message says There was a problem sending the command to the program.

Hi,
Have you try to un-select the Ignore other applications that use Dynamic Data Exchange (DDE) setting?
Click the Microsoft Office Button, and then click Excel Options.
Click Advanced, and then click to clear the Ignore other applications that use Dynamic Data Exchange (DDE)
check box in the General area.
Click OK.
If the problem cannot resolve, the Run as administrator may selected.
Go to Office default install location: C:\Program Files\Microsoft Office\Office12.
Right-click EXCEL.EXE > Properties >
Compatibility tab.
Under Privilege Level, uncheck Run this program as an administrator
check box.
Best regards.

After updating to Firefox 3.6.9, when I click on a link in Outlook email, I get a message which says "General failure. The URL was: .... An error occurred in sending the command to the applicatio." and the link will not open. How can I fix this?

I updated Firefox yesterday to 3.6.9. When I receive a URL link in an email within Outlook, I cannot open the link in Firefox. As I said in the question, when I click on the link, a Microsoft Office Outlook error message appears which states that a General failure has occurred in sending the command to the application (which is Firefox). I am using Office 2007 This did not occur prior to the upgrade of Firefox.

See this lnk for a fix, it worked for me!

Excel won't open and error message There was a problem sending the command to the programe

Hi there
I'd be grateful for your help.
I've just bought a new laptop and installed Office 2013. I used Excel 2013, did what I needed to do and saved it. This was 5 days ago.
Today, I've tried opening the file from my desktop and get the error message 'There was a problem sending the command to the program'.
And when I try to open Excel to do the DDE fix, which seems to be the best suggestion, I can't open Excel at all. I've tried to get into it from the Apps screen.
Any help would be gratefully appreciated.
Thanks

Don't seem like this can be fixed so I went back to version 6.0.2 which works good.
I have Chrome now as my default browser and will not use fire fox until they fix it!
Chrome works great!
