What html code will start an EXE (program) with a click on a webpage link?

The code in bold below worked. After I switched my browser from IE 11 to Firefox to get the hover on hotspots to work, the program gave me this error message. I moved the EXE file to my local file folder and tried it as shown below. Still no success. Any suggestions?

Perhaps this might be helpful:
https://addons.mozilla.org/en-US/firefox/addon/opendownload-10902/
It allows executables in Firefox to be run - it is an extenstion, though, so it must be installed in Firefox before your page will work.
Another option is this solution, but it will still require a manual change in Firefox:

Or this: http://stackoverflow.com/questions/6472435/running-exe-in-firefox-why- do-i-get-an-error
However, you will still have problems with getting it to work cross-browser. Honestly, browsers are not supposed to have access like that to the client side file system, which absolutely makes sense for the web.
That is why you may have to approach the solution from a different angle - perhaps create a server side cloud version of your application(s) which can be easily accessed and run by your family members. I believe you used C to develop the applications? Although I have no experience with this framework, Wt might be a solution to convert your projects to server side applications:

Disk still wakes up with laptop-mode-tools

Hi all,
I have a Thinkpad x61 and I'm trying to manage power use with laptop-mode-tools, but I'm having trouble with the harddrive waking up too much. I have it configured so that lm-tools activates when the power is disconnected, and sure enough, a few seconds later the harddrive spins down. But 1-2 seconds later it spins back up! iotop indicates that dhcpcd is writing to the drive, and thus waking it up.
I thought lm-tools was set so that I could "potentially lose up to 10 minutes of work." Shouldn't that mean that up to 10 minutes of writes get buffered in ram instead of waking up the harddrive? If I disable the network, dhcpcd stops waking things up, but if I save a buffer from emacs, the harddrive instantly wakes up, so it looks like there's no buffering going on...
Here are some relevant settings while in laptop-mode:
$ dmesg|tail
[15425.800826] EXT4-fs (sda1): re-mounted. Opts: data=ordered,commit=600
[15425.982220] EXT4-fs (sda2): re-mounted. Opts: data=ordered,commit=600
$ cat /proc/sys/vm/dirty_writeback_centisecs
60000
$ cat /proc/sys/vm/dirty_expire_centisecs
60000
$ cat /proc/sys/vm/dirty_bytes
0
$ cat /proc/sys/vm/dirty_background_bytes
0
$ cat /proc/sys/vm/dirty_background_ratio
1
It looks like dirty_writeback is getting set to 10 minutes and the journal commit rate is also set to 10 minutes. Should dirty_background_bytes and dirty_bytes be nonzero?
Here are some relevant lines from /etc/laptop-mode/laptop-mode.conf:
LM_BATT_MAX_LOST_WORK_SECONDS=600
CONTROL_READAHEAD=1
LM_READAHEAD=3072
CONTROL_NOATIME=0
USE_RELATIME=1
CONTROL_HD_IDLE_TIMEOUT=1
LM_BATT_HD_IDLE_TIMEOUT_SECONDS=10
BATT_HD_POWERMGMT=1
CONTROL_HD_WRITECACHE=1
NOLM_AC_HD_WRITECACHE=1
NOLM_BATT_HD_WRITECACHE=0
LM_HD_WRITECACHE=0
Any ideas what I'm missing?
Thanks in advance for any suggestions!

Vim calls fsync(2) when writing files and swap files per default. One can control this behavior with the fsync and swapsync options.
I don't know if Emacs has similar options.

Stopping a program in debug mode

Hi all,
i have am having a intermitent issue with a program. first let me give you the issue and then the specs.
This is an inconsistant program lockup. when the program runs in an, .exe format it runs fine for an hour to a couple of days and then goes to a white screen and freezes. the program is basically just continiously reading a DAQ card and comparing readings to set values.
if i have the program running in Debug mode thru CVI and it freezes, CVI sees it as running (in top left hand corner of CVI interface), if i push the stop button (break execution) the break execution dims but the program never stops and the Running indication is still active.
question--- is there another way to stop the program while it is in this frozen state to see where the issue is hanging up. like a hard stop command ????
I can only stop the program by using task manager and ending CVI there. which does me no good in finding the freezing point.
CVI 2012 sp1
with a PCI 6071E DAQ

There isn't an easy way to debug this kind of events.
The behaviour you are seeing (stop button dimmed after click but program that soesn't stop) normally happens when the program is stuck in a operation waiting for it to finish before breaking into the IDE. It may be a popup message waiting for user input, a I/O operation with a long or infinite timeout...
To deal with such a kind of thing you can for example write operations to a log file -one line before each critical call and one after that- so that you can at least see where it hanged. Alternatively you can use DebugPrintf to write messages to the debug output window: if in the IDE you have this window listed in Windows menu, if an .exe you can use utilities like DebugView to receive those messages. Another alternative can be to use Remote Debugging.
However, this is only a list of possible instruments and techniques: solving these problems usually ends up in a boring task of trial and error to narrow down to the critical situation and trying to overcome it.
Proud to use LW/CVI from 3.1 on.

Start stop while loop with tab control

I want to be able to start and stop a while loop by entering and leaving a tab. I am using an event structure to do so but it doesn't seem elegant or the right way to do this. The only way I was able to get it to kind of work is by unchecking the lock front panel box in the event structure. I have attached a sample vi of what I have so far.
Solved!
Go to Solution.

Loop test.vi ‏16 KB

The problem is that you can't even stop the program by hitting the stop button until you leave the tab, which is not a friendly user interface.
Event structures should just handle basic user events. Any given event case should not take a long time to run. While you are in the diagnostics tab, your code is stuck in that while loop. Although fixing the lock front panel allows you to do other things, the LabVIEW is just queuing up all of those other UI events (like Stop button value change) and can't handle them until the inner while loop stops and allows the outer while loop to iterate again.
You should have a parallel while loop to handle the waveform graph. You can use notifiers or queues or an action engine FGV (see Ben's Action Engine Nugget) to pass the starting or stopping of the waveform graph update to the parallel while loop.

I Need advise with laptop-mode-tools

Hello,
I installed the laptop-mode-tools to control my external harddrive. I followed closely the wiki and I managed to configure the
/etc/laptop-mode/conf.d/usb-autosuspend.conf
exactly, it is explained in the wiki.
It works (kind of) but I don't know this is the right behaviour. It powers off my external harddrive, but after a while it powers it on again even if I don't touch the external harddrive. I thought when once the harddrive powered off it remains so until I use it.
Is this the proper behavior of the laptop-mode-tools program?
These are my configuration settings (Exactly the same suggested in the wiki).
DEBUG=0
CONTROL_USB_AUTOSUSPEND=1
BATT_SUSPEND_USB=1
LM_AC_SUSPEND_USB=1
NOLM_AC_SUSPEND_USB=0
AUTOSUSPEND_TIMEOUT=2
Thanks,
jmak

Some DE have index services (e.g. gnome) in the background. Maybe it is one of those which wakes it up again. To check you can install something like "iotop" and have a look at the processes when the drive gets woken up.
Another avenue is that the drive itself has powermanagement options to be set additionally. You can check on them with hdparm.

Trouble with Laptop-Mode-Tools, AC Plug-In

I can't get Laptop-Mode-Tools to recognize when I plug my AC in, I have options for "AC_" as it says are allowed in the man page and ArchWiki, although there are no examples of just having the prefix "AC_".
However, it says it should behave in the same way as "BATT_" does, independant of the laptop-mode status.
I have LM enabled for AC in laptop-mode.conf, and acpi_listen has output for the AC in/out. My current workaround is to have it as it is, with "LM_AC_*", but having entries for exclusively battery and AC is easier for me as I plan to always keep Laptop-Mode-Tools enabled.
Is there something I misconfigured, or may I have misunderstood the manual/wiki?
Alternatively, how would I go about debugging? I noticed there was a variable enabling debugging, but I couldn't find where the debugging output occurs. I am a little new with regards to standard debugging practice.

I'm terribly sorry, I fixed everything I had made bold. I was trying to make the technical things stand out for people that were just glancing at the post. But you're absolutely right, I should have used more discretion.
As for the configuration, I did not expect it to magically do what I want. I will provide a more concrete example of what I am talking about, if it helps.
In /etc/laptop-mode/conf.d/lcd-brightness.conf, I have BATT_BRIGHTNESS_COMMAND="echo 0". This works: when I unplug AC, 0 gets output to /sys/class/backlight/acpi_video0/brightness.
However, when I attempt AC_BRIGHTNESS_COMMAND="echo 15" (less than /sys/class/backlight/acpi_video0/max_brightness, hopefully demonstrating my reading of laptop-mode.conf), it is unsuccessful. Instead, I currently use LM_AC_BRIGHTNESS_COMMAND="echo 15" as a workaround. BATT_BRIGHTNESS_COMMAND works without editing /etc/acpid/handler.sh, I was simply wondering why the AC counterpart does not.
I hope I have now supplied enough information now allows us to be on the same page, and I apologize again for the offensive formatting.

Start/Stop Web Modules with JMX

Does anyone know if there is a possibility in OC4J to start/stop/reload web applications via JMX?
When I navigate with the System MBean Browser to a WebModule MBean, e.g. oc4j:j2eeType=WebModule,name=defaultWebApp,J2EEApplication=default,J2EEServer=standalone , the stateManageable attribute says false, and there are no start() and stop() operations available.
Is there any other way to do that, besides starting and stopping the parent J2EEApplication MBean, perhaps with some non-JSR77 MBean?
Best regards,
Volker

Arch news says KDM is now started as user(Fixed with new Dnld)

My system runs in ram and kdmrc has been changed to allow root log-in.
Does the KDM change affect the log-in as root?
Last edited by lilsirecho (2010-09-04 04:22:15)

I have used kde log-in for years, in the last year or so with kde4 I employed root log-in by modifying kdmrc to enable root log-in.
The recent upgrade to kde4 seems to have re-imposed user as the only mode permitted.
There is no Konsole terminal nor does Dolphin respond with a menu.
This has occured on two HDD's, one is a backup for the other.
I can log-in with kmrc enabled but the condition above exists, no terminal...no pacman...nada!
The log-in requires that I enter root and the passwd ( I don't think it needs one). This is with kdmrc root enabled.
This entry of root is not encountered with another boot device which has not been upgraded to kde4.5-1. That device has root inserted and only needs passwd entered. It has kdmrc enabled. Everything is normal in that device, as I am using it now.
Thus, because both hdd's have identical problem, it appears to have been a mod to kde4 to prevent root use.
This restriction is also applied to vlc which won't run in root without modifying it.
I would appreciate knowing for sure that kde4.5-1 cannot be entered by root login without compromising the performance.
When I select console log-in, I can use X and perform pacman activities.
I am 85 years old for a couple of weeks and don't appreciate being big-brothered in an open linux system.
Security is the reason given for the change in root log-in.....the Pentagon has security but was compromised....so much for security..a pipe dream...
I see no other reason for losing the critical elements in the kde desktop except for the requirement that only users can log-in to it successfully.

How do you start a java program with more RAM alloaction

ASP code to start a Java program (with parameters)

Hi! All,
I am trying to write some ASP code which should start a java program. Does anybody know a simple way to do this? Am new to ASP
Thanks

It doesn't have anything to do with java.
Basically you need to make a system call which will start an external application. The external application can be anything including something like "java MyClass".
So either find an ASP forum/board/newsgroup to ask how to do a system call or read some docs on it.

Starting/Stopping 9iAS Infrastructures with batch files

I created the following two batch files to start and stop my iAS Infrastructure. I found that if I used the services settings of automatic, all did not go well.
start.bat:
@ECHO OFF
cls
ECHO About to start the listener
net start Oracle9ias_InfraTNSListener
ECHO About to start the database
net start OracleServiceIASDB
ECHO About to start the OID monitor
e:\ora9iasinfra\bin\oidmon start
ECHO About to start the OID server
e:\ora9iasinfra\bin\oidctl server=oidldapd configset=0 instance=1 start
ECHO About to start the website
net start Oracle9ias_infraEMWebsite
ECHO About to start opmn and OC4j
e:\ora9iasinfra\dcm\bin\dcmctl start -ct ohs
e:\ora9iasinfra\dcm\bin\dcmctl start -co OC4J_DAS
stop.bat:
@echo off
cls
ECHO About to stop the website
net stop Oracle9ias_infraEMWebsite
ECHO About to stop opmn and OC4j
e:\ora9iasinfra\dcm\bin\dcmctl shutdown
ECHO About to stop the OID server
e:\ora9iasinfra\bin\oidctl server=oidldapd configset=0 instance=1 stop
ECHO About to stop the OID monitor
e:\ora9iasinfra\bin\oidmon stop
ECHO About to stop the database
net stop OracleServiceIASDB
ECHO About to stop the listener
net stop Oracle9ias_InfraTNSListener
When I execute the batch files sometimes they work and sometimes they don't, for example after starting, occasionally the Apache process has not been created, and sometimes processes won't stop.
However if I enter each command seperatly all works OK. Can anyone suggest a reason for this, maybe ordering is significant or a time delay may be required between certain actions?. Also after starting the website manager the process managers for both the infra and ias instances are started (I have installed both the iAS and the Infrastucture on the same machine - this all works fine when started as a series of individual commands but not when through batch files).
Also If I try to use:
SQLPLUS /NOLOG
SQL>CONNECT sys/password@iasdb as sysdba
SQL>Start
I also get an 'unable to create a dedicated server' error. I can start/stop the database through the enterprise manager in either standalone or management server configuration without any errors. Can anyone shed any light on this?. I have set both TNS_ADMIN and ORACLE_SID correctly.

Thanks, I had read that and it was very informative. I did however solve my problem using a few other threads that have been posted about the runtime.runtime().exec commands. Thanks for you help.

Stop whole program with one button

Hi, I've written a program for reading some values out of a measurement instrument. Now i want to have one button which stops the entire program no matter in which loop or which subVI the program is in. I have a subvi to make a connection to the device and i can't get out of this when he is trying to make that connection. Also the stopbutton i've used now is only read when the program is in a specific while loop. Can is solve this problem. I've attatched my program.

You will need to use global variables to communicate between VIs. Don't make it a habit since using them can lead to race conditions and synchronization problems, so I would recommend that you look into functional global variables, semaphores, notifiers and queues. The Help document in LabVIEW has detailed explanations on each one of them.
You will need to call a subVI in parallel if you want to continue with the execution of other tasks in your mainVI. I have created a quick example which shows the use of a global variable and using a subVI in parallel.
