One more thing: after some updates of MIUI developer mode becomes disabled. I was sure, that is was turned on, but i couldn't start the application. So i reenabled developer mode and everything started to work. I've encountered this problem several times. Hope it helps.
For quick steps just check summary. If interested to know details, go on to read below.
adb is a daemon. Doing ps adb
we can see its process.
shell@grouper:/ $ ps adb
USER PID PPID VSIZE RSS WCHAN PC NAME
shell 133 1 4636 212 ffffffff 00000000 S /sbin/adbd
I just checked what additional property variables it is using when adb is running as root and user.
adb user mode :
shell@grouper:/ $ getprop | grep adb
[init.svc.adbd]: [running]
[persist.sys.usb.config]: [mtp,adb]
[ro.adb.secure]: [1]
[sys.usb.config]: [mtp,adb]
[sys.usb.state]: [mtp,adb]
adb root mode :
shell@grouper:/ # getprop | grep adb
[init.svc.adbd]: [running]
[persist.sys.usb.config]: [mtp,adb]
[ro.adb.secure]: [1]
[service.adb.root]: [1]
[sys.usb.config]: [mtp,adb]
[sys.usb.state]: [mtp,adb]
We can see that service.adb.root
is a new prop variable that came up when we did adb root.
So, to change back adb to user from root, I went ahead and made this 0
setprop service.adb.root 0
But this did not change anything.
Then I went ahead and killed the process (with an intention to restart the process). The pid
of adbd
process in my device is 133
kill -9 133
I exited from shell automatically after I had killed the process.
I did adb shell
again it was in user mode.
SUMMARY :
So, we have 3 very simple steps.
(pid of adbd)
After these steps just re-enter the shell with adb shell
and you are back on your device as a user.
No Root and no ADB tools required method. Install MyAppSharer app from the play store.
Launch your app and keep it in foreground.
Run the below command:
adb shell dumpsys window windows | find "mcurrentfocus"
As to the short script, the following runs on my Linux host
#!/bin/bash
HOST_DIR=<pull-to>
DEVICE_DIR=/sdcard/<pull-from>
EXTENSION="\.jpg"
while read MYFILE ; do
adb pull "$DEVICE_DIR/$MYFILE" "$HOST_DIR/$MYFILE"
done < $(adb shell ls -1 "$DEVICE_DIR" | grep "$EXTENSION")
"ls minus one" lets "ls" show one file per line, and the quotation marks allow spaces in the filename.
Solution for me was (thx to David Ljung Madison post)
adb kill-server
Building on @Bhaskar's answer and others, here's a full command to unlock (tested on Pixel 3):
adb shell input keyevent 26 && adb shell input keyevent 82 && adb shell input text <password> && adb shell input keyevent 66
I have thesame issue before but i solved it easily by just following this steps:
*connect your android phone in a debugging mode (to enable debugging mode goto settings scroll down About Phone scroll down tap seven times Build Number and it will automatically enable developer option turn on developer options and check USB debugging)
download Universal ADB Driver Installer
*choose Adb Driver Installer (Universal)
*install it *it will automatically detect your android device(any kind of brand) *chose the device and install
Make sure it's not running in the task-manager processes. If so, end the process and then start it from a command prompt as in a previous answer. This worked for me.
You need not specify receiver. You can use adb instead.
adb shell am broadcast -a com.whereismywifeserver.intent.TEST
--es sms_body "test from adb"
For more arguments such as integer extras, see the documentation.
if you are using Android Studio in MAC OS X , you could exec the following command in your terminal app:
echo 'alias adb="/Applications/Android\ Studio.app/sdk/platform-tools/adb"' >> .bashrc
exec $SHELL
and next:
adb devices
and you should be showing a list with your android devices connected via USB cable in your MAC, for example something like this:
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
deb7bed5 device
use adb Shell Commands to simulate the touch event
adb shell input tap x y
and also
adb shell sendevent /dev/input/event0 3 0 5
adb shell sendevent /dev/input/event0 3 1 29
You can read the binary from stdout instead of saving the png to the sdcard and then pulling it:
adb shell screencap -p | sed 's|\r$||' > screenshot.png
This should save a little time, but not much.
adb tcpip 5555
adb connect <DEVICE_IP_ADDRESS>:5555
adb devices
In windows, this command works for me to show current activity name
adb shell dumpsys window windows | find "mCurrentFocus"
Output:
mCurrentFocus=Window{a43a55b u0 com.android.contacts/com.android.contacts.activities.TwelveKeyDialer}
Other solutions with "grab" produce error in my windows pc
'grep' is not recognized as an internal or external command, operable program or batch file.
So, using "find" solve the error in my case.
For Power-Shell
./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'
For linux(burrowing asnwer from @0x8BADF00D)
adb shell getprop | grep "model\|version.sdk\|manufacturer\|hardware\|platform\|revision\|serialno\|product.name\|brand"
For single string find in power shell
./adb shell getprop | Select-String -Pattern 'model'
or
./adb shell getprop | Select-String -Pattern '(model)'
For multiple
./adb shell getprop | Select-String -Pattern '(a|b|c|d)'
For anyone still confused about how to define the service name parameter, the forward slash goes immediately after the application package name in the fully qualified class name.
So given an application package name of: app.package.name
And a full path to the service of: app.package.name.example.package.path.MyServiceClass
Then the command would look like this:
adb shell am startservice app.package.name/.example.package.path.MyServiceClass
How to Enable USB Debugging for LG Optimus (LGD415). Android version 4.4.2 (KitKat)
Go to this website and download the drivers to your phone:
http://www.lg.com/us/support/mobile-support
For example, mine would be:
http://www.lg.com/us/support-mobile/lg-LGD415RD. Then click on “Software Update & Drivers”
On your phone, you need to enable USB debugging. To do so,
Go to “Settings”.
Go to “About Phone”
Go to “Software Information”
Tap “Build number” five times.
A pop-up will appear saying “You are now a developer”. Your’re not done yet.
Go back to your phone’s home page by pushing the home button.
Go to “Settings”.
Go to “Developer options”
Click the “USB debugging- Turn on debug mode when USB is connected”. A blue checkmark will appear.
(EDIT: If USB Debugging is greyed out, unplug your phone. USB Debugging should no longer be greyed out. If it is not greyed out, check the box and plug your phone into your PC.)
Unplug your phone from your PC. Then plug it back in. On the pop-up, make sure you set it to “Media Sync (MTP)”.
Now your phone will show up on an option when you want to run your app in Eclipse.
(Look for dialog box on phone and agree to allow debugging connection with your computer.)
(Also, go to Control Panel | Device Manager and make sure there are TWO entries for your phone, similar to those expanded below.)
I finally found out how to do this! Basically you need to run adb shell
first and then while you're in the shell run su
, which will switch the shell to run as root!
$: adb shell
$: su
The one problem I still have is that sqlite3 is not installed so the command is not recognized.
For anyone coming to this question wondering how to do this in Eclipse, You can remove the displayed text from the logCat using the button provided (often has a red X on the icon)
You can reboot the device by sending the following broadcast:
$ adb shell am broadcast -a android.intent.action.BOOT_COMPLETED
I keep this build-and-run script handy, whenever I am working from command line:
#!/usr/bin/env bash
PACKAGE=com.example.demo
ACTIVITY=.MainActivity
APK_LOCATION=app/build/outputs/apk/app-debug.apk
echo "Package: $PACKAGE"
echo "Building the project with tasks: $TASKS"
./gradlew $TASKS
echo "Uninstalling $PACKAGE"
adb uninstall $PACKAGE
echo "Installing $APK_LOCATION"
adb install $APK_LOCATION
echo "Starting $ACTIVITY"
adb shell am start -n $PACKAGE/$ACTIVITY
Check out Android Documentation Managing Virtual Devices
My Nexus 5 phone did not have developer options in the settings menu. I had to do the following:
On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to Settings > About phone and tap Build number seven times. Return to the previous screen to find Developer options.
My fix to this issue:
Why don't you try to grep the return of your command ? Something like :
adb devices -l | grep 123abc12
It should return only the line you want to.
Not all USB cables can transfer data. Try using a different USB cable if your device is charging, but doesn't establish a connection to your machine.
It seems trivial. But it's worth a try if each and every other solution that normally works, doesn't.
I Solved it. I just had to add the path of android studio's platform-tools after removing my earlier eclipse's path. I don't know, maybe some conflict in the command.
Make sure you enter the full package name with application name:
com.domain.app
Sounds a bit familiar with my problem: aapt not found under the right path
I needed to clean all open projects to get it working again...
1) Go to Phone Setting > Developer options > Revoke USB debugging.
2) Turn off USB debugging and Restart Again.
It will work definitely, in my case it worked.
I am using Mac 10.11.1 and using android studio 1.5, I have my adb "/Users/user-name/Library/Android/sdk/platform-tools"
Now edit you bash_profile
emacs ~/.bash_profile
Add this line to your bash_profile, and replace the user-name with your username
export PATH="$PATH:/Users/user-name/Library/Android/sdk/platform-tools"
save and close. Run this command to reload your bash_profile
source ~/.bash_profile
This helped me at the end:
Quick guide:
Download Google USB Driver
Connect your device with Android Debugging enabled to your PC
Open Device Manager of Windows from System Properties.
Your device should appear under Other devices
listed as something like
Android ADB Interface
or 'Android Phone' or similar. Right-click that and
click on Update Driver Software...
Select Browse my computer for driver software
Select Let me pick from a list of device drivers on my computer
Double-click Show all devices
Press the Have disk
button
Browse and navigate to [wherever your SDK has been installed]\google-usb_driver and select android_winusb.inf
Select Android ADB Interface
from the list of device types.
Press the Yes
button
Press the Install
button
Press the Close
button
Now you've got the ADB driver set up correctly. Reconnect your device if it doesn't recognize it already.
If your Application used to be debuggable, and suddenly it's no more debuggable.Here is my solution
USB debug
switch in your phone.Click on Attach Debuger to Android Process and Click On Restart ADB.
Note that if you use Android Studio and download through its SDK Manager, the SDK is downloaded to ~/Library/Android/sdk
by default, not ~/.android-sdk-macosx
.
I would rather add this as a comment to @brismuth's excellent answer, but it seems I don't have enough reputation points yet.
Use this command in cmd:
adb shell pm uninstall -k com.packagename
For example:
adb shell pm uninstall -k com.fedmich.pagexray
The -k
flag tells the package manager to keep the cache and data directories around, even though the app is removed. If you want a clean uninstall, don't specify -k
.
...the OP’s own answer is wrong in so far, that there are no “special system permissions”. – The “no permission” problem boils down to ... no permissions.
Unfortunately it is not easy to debug, because adb makes it a secret which device it tries to access! On Linux, it tries to open the “USB serial converter” device of the phone, which is e.g. /dev/bus/usb/001/115 (your bus number and device address will vary). This is sometimes linked and used from /dev/android_adb.
lsusb
will help to find bus number and device address. Beware that the device address will change for sure if you re-plug, as might the bus number if the port gets confused about which speed to use (e.g. one physical port ends up on one logical bus or another).
An lsusb-line looks similar to this: Bus 001 Device 115: ID 4321:fedc bla bla bla
lsusb -v
might help you to find the device if the “bla bla bla” is not hint enough (sometimes it does neither contain the manufacturer, nor the model of the phone).
Once you know the device, check with your own eyes that ls -a /dev/bus/usb/001/115
is really accessible for the user in question! Then check that it works with chmod
and fix your udev setup.
PS1: /dev/android_adb can only point to one device, so make sure it does what you want.
PS2: Unrelated to this question, but less well known: adb has a fixed list of vendor ids it goes through. This list can be extended from ~/.android/adb_usb.ini, which should contain 0x4321 (if we follow my example lsusb line from above). – Not needed here, as you don’t even get a “no permissions” if the vendor id is not known.
Answer 1 worked perfectly for me. I tested it on a new MID 10' tablet. Here are the lines I added in the .inf file and it installed without a problem:
;Google MID
%SingleAdbInterface% = USB_INSTALL, USB\Vid_18d1&Pid_0003&MI_01
%CompositeAdbInterface% = USB_INSTALL, USB\Vid_18d1&Pid_0003&Rev_0230&MI_01
You could just drag the adb.exe
on to the command prompt from sdk/platformtools
and leave a space and type the command you want: like logcat
.
It looks like this for me:
C:\adt-bundle-windows-x86-20130917\adt-bundle-windows-x86-20130917\sdk\platform-tools.exe logcat
and hit enter.
just to add the full command:
adb shell ls -R | grep filename
this is actually a pretty fast lookup on Android
To kill from the application, you can do:
android.os.Process.killProcess(android.os.Process.myPid());
I did it using this command:
syntax: adb push filename.extension /sdcard/0/
example: adb push UPDATE-SuperSU-v2.01.zip /sdcard/0/
Every answer I've read indicates the SUBSYSTEM=="usb"
. However, my (perhaps ancient) udev needed this to be changed to DRIVER=="usb"
. At last I can run the adb server as a non-root user... yay.
It can be instructive to look at the output of udevmonitor --env, followed by the output of
udevinfo -a -p <DEVICE_PATH_AS_REPORTED_BY-udevmonitor>
By default CM10 only allows root access from Apps not ADB. Go to Settings -> Developer options -> Root access, and change option to "Apps and ADB".
If the above CMD command option is not working and you cannot make it work in any other way then follow this below.
Click on below link
and download the first link with name ADB Kits ( contains adb.exe and necessary .dll files).
After downloading replace these files with the ones in the path
Android/Sdk/platform-tools/
Now click on adb.exe and it will open cmd and will start the adb server.
Now it will detect the device and no problem. OOOOOllllaaaaa.....
If the Problem persists again then do the same... save the folder somewhere.... just replace files... it will detect the device automatically then
You probably haven't run the Android SDK in forever. So you probably just have to update it. If you open the Android Studio Software it'll probably let you know that and ask to update it for you. Otherwise refer to following link: Update Android SDK
Sometimes you just need to recreate new device
I tried all the solutions above, it fixes the issue sometimes, but still from time to time I happened to get stuck with the "Waiting for the debugger to attach" message box.
The final solution in my case was to unplug all the Android devices but the one I want to debug on. I don't know which one is the culprit: the Nexus 7 running JB 4.2, the HTC One X running ICS, the HTC Desire S running Gingerbread, or the combintation of the 3, but as soon as I only have one device plugged in, it runs smooth as silk.
One other difference:
More detail code trace into inside AOSP Framework can be found here:
http://www.srcmap.org/sd_share/4/aba57bc6/AOSP_adb_shell_input_Code_Trace.html#RefId=7c8f5285
For those people to whom none of the answers worked.... try closing the chrome://inspect/#devices tab in chrome if opened... This worked for me.
Here is what worked for me:
adb -d shell "run-as com.example.test cat /data/data/com.example.test/databases/data.db" > data.db
I'm printing the database directly into local file.
If you have access to the application package, then you can install with the -r option and it will kill the process if it is currently running as a side effect. Like this:
adb -d install -r MyApp.apk ; adb -d shell am start -a android.intent.action.MAIN -n com.MyCompany.MyApp/.MyActivity
The -r option preserves the data currently associated with the app. However, if you want a clean slate like you mention you might not want to use that option.
I found one solution with Nexus 5, and TWRP installed. Basically format was the only solution I found and I tried all solutions listed here before: ADB Android Device Unauthorized
Ask Google to make backup of your apps. Save all important files you may have on your phone
Please note that I decline all liability in case of failure as what I did was quite risky but worked in my case:
Enable USB debugging in developer option (not sure if it helped as device was unauthorized but still...)
Make sure your phone is connected to computer and you can access storage
Download google img of your nexus: https://developers.google.com/android/nexus/images unrar your files and places them in a new folder on your computer, name it factory (any name will do).
wipe ALL datas... you will have 0 file in your android accessed from computer.
Then reboot into BOOTLOADER mode... you will have the message "you have no OS installed are you sure you want to reboot ?"
Then execute (double click) the .bat file inside the "factory" folder.
You will see command line detailed installation of the OS. Of course avoid disconnecting cable during this phase...
Phone will take about 5mn to initialize.
Just a tiny update with built-in wireless debugging in Android 11:
adb pair [IP_ADDRESS]:[PORT]
and type pairing code.For me, it's that the USB cable was not plugged in all the way into the slot. Although it shows charging on my Nexus 5.
also make sure adb isn't running in your processes automatically. If it's there right click open file location, figure out what is starting it, kill it with fire. Run the updated adb from an updated android sdk platform tools. This was the issue with mine, hope it helps someone.
UPDATE 2020
Database Inspector (for Android Studio version 4.1). Read the Medium article
For older versions of Android Studio I recommend these 3 options:
In build.gradle:
dependencies {
// Stetho core
compile 'com.facebook.stetho:stetho:1.5.1'
//If you want to add a network helper
compile 'com.facebook.stetho:stetho-okhttp:1.5.1'
}
Initialize the library in the application object:
Stetho.initializeWithDefaults(this);
And you can view you database in Chrome from chrome://inspect
My Android Studio version 3.6.1
After getting updated the latest version I have been facing this problem for few hours. My steps to solve this:
-> Updated sdk platform-tools [though it's not fetching my device yet]
-> Change the USB cable, then my 2 devices both are getting connected with Studio and run my app successfully.
I don't know this silly step might help anyone but U can have a look on that. I just share my experience, Thanks.
I had just the same problem, here's how to deal with it:
Someone mentioned something similar earlier.
Thanks for the comments below.
in Developer options,
(if there is no a Developer option menu, you have to click 3 times build number of Phone State menu to be developer. you can sse a developer option menu.)
You can use
adb shell ps | grep apps | awk '{print $9}'
to produce an output like:
com.google.process.gapps
com.google.android.apps.uploader
com.google.android.apps.plus
com.google.android.apps.maps
com.google.android.apps.maps:GoogleLocationService
com.google.android.apps.maps:FriendService
com.google.android.apps.maps:LocationFriendService
adb shell ps returns a list of all running processes on the android device, grep apps searches for any row with contains "apps", as you can see above they are all com.google.android.APPS. or GAPPS, awk extracts the 9th column which in this case is the package name.
To search for a particular package use
adb shell ps | grep PACKAGE.NAME.HERE | awk '{print $9}'
i.e adb shell ps | grep com.we7.player | awk '{print $9}'
If it is running the name will appear, if not there will be no result returned.
If you launch the VM with the the launchpad (genymotion binary where you download the VMs) and you set the Android SDK path into the application parameters the connection is automatic and you don't need to run adb connect
You can find the information in the Genymotion Docs.
If you get your adb from Android Studio (which most will nowadays since Android is deprecated on Eclipse), your adb
program will most likely be located here:
%USERPROFILE%\AppData\Local\Android\sdk\platform-tools
Where %USERPROFILE%
represents something like C:\Users\yourName
.
If you go into your computer's environmental variables and add %USERPROFILE%\AppData\Local\Android\sdk\platform-tools
to the PATH (just copy-paste that line, even with the % --- it will work fine, at least on Windows, you don't need to hardcode your username) then it should work now. Open a new command prompt and type adb
to check.
I found this question after seeing the 'more than one device' error, with 2 offline phones showing:
C:\Program Files (x86)\Android\android-sdk\android-tools>adb devices
List of devices attached
SH436WM01785 offline
SH436WM01785 offline
SH436WM01785 sideload
If you only have one device connected, run the following commands to get rid of the offline connections:
adb kill-server
adb devices
If you're using a USB Type-C cable, check if it has the charging and data transfer capability. Many USB Type-C cables are for charging only, and are not recognized by Android Studio.
i have solve this problem several times using the same steps :
1- Close Eclipse.
2- Restart your phone.
3- End adb.exe process in Task Manager (Windows). In Mac, force close in Activity Monitor.
4- Issue kill and start command in \platform-tools\
C:\sdk\platform-tools>adb kill-server
C:\sdk\platform-tools>adb start-server
5- If it says something like 'started successfully', you are good.
but now it's doesn't work cause i have an anti-virus called "Baidu", this program have run "Baidu ADB server", finally i turn this process off and retry above steps it's work properly.

It appears that you're still trying to execute adb
with ./adb
. That asks the shell to run the program named adb
in the current working directory.
Try just adb
without ./
.
I think this was because the option for USB debugging wasn't checked on the device
I know this thread is old, but I think this could still help. Almost all the time "it just works" on OS X, but sometimes new/prototype or obscure devices aren't picked up. Try to help it out with these steps (I'm not near my Mac right now, but I did this last night and think I remember):
Open System Profiler and find the device on USB. View it's details to find the Vendor ID. For example, Motorola devices will show 0x2bb8. Or just Google for your vendor's hardware id.
If nothing shown, make sure to try different cables. Android File Transfer is good for detecting the device if you have a valid cable.
Edit ~/.android/adb_usb.ini
to include that Vendor ID. If the file doesn't exist, create it with that line only.
Restart ADB
adb kill-server
adb start-server
Maybe unplug/plugin your phone.
And hopefully you see your device.
you can copy this db file to somewhere in eclipse explorer (eg:sdcard or PC),and you can use sqlite to access and update this db file .
After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.
* The arguments which may be supplied in the recovery.command file:
* --send_intent=anystring - write the text out to recovery.intent
* --update_package=path - verify install an OTA package file
* --wipe_data - erase user data (and cache), then reboot
* --wipe_cache - wipe cache (but not user data), then reboot
* --set_encrypted_filesystem=on|off - enables / diasables encrypted fs
Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:
adb shell
recovery --wipe_data
Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.
EDIT:
For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command
For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c
In addition to all the other answers you received, I want to explain the unknown option -- o
error: Your command was
$ adb shell 'su -c mount -o rw,remount /system'
which calls su through adb. You properly quoted the whole su command in order to pass it as one argument to adb shell
. However, su -c <cmd>
also needs you to quote the command with arguments it shall pass to the shell's -c
option. (YMMV depending on su
variants.) Therefore, you might want to try
$ adb shell 'su -c "mount -o rw,remount /system"'
(and potentially add the actual device listed in the output of mount | grep system
before the /system
arg – see the other answers.)
All these input keyevent
combinations are SO android/hardware dependent, it's a pain.
However, I finally found the combination for my old android 4.1 device :
adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
adb shell "input keyevent KEYCODE_DPAD_LEFT;input keyevent KEYCODE_DPAD_RIGHT;input keyevent KEYCODE_DPAD_CENTER"
This is indeed a strange error that can be caused by multidexing your app. To get around it, use the following block in your app's build.gradle file:
android {
splits {
abi {
enable true
reset()
include 'x86', 'armeabi-v7a'
universalApk true
}
}
...[rest of your gradle script]
In my case the solution was this on an Ubuntu based OS:
adb kill-server
sudo cp ~/Android/Sdk/platform-tools/adb /usr/bin/adb
sudo chmod +x /usr/bin/adb
adb start-server
You can find your app package name by below command:
adb shell pm list packages
Above command returns package list of all apps, Example:
org.linphone.debug
.
.
com.android.email
Now I want to start app linphone by using below command and this worked for me:
adb shell am start org.belphone.debug
After you ensure you have enabled USB debugging unlock your phone and plug it into your machine via USB. You will be then asked to authorize communication with the computer you have connected to. It will also show computers RSA key fingerprint.
Accept it and you are good to go!
If all other solutions did not work for your device try this guide how to make a truly universal adb and fastboot driver out of Google USB driver. The resulting driver works for adb
, recovery
and fastboot
modes in all versions of Windows.
You have to grant the Superuser
right to the shell app (com.anroid.shell

In my case, I use Magisk to root my phone Nexsus 6P (Oreo 8.1). So I can grant Superuser

What's dumpsys and what are its benefit
dumpsys is an android tool that runs on the device and dumps interesting information about the status of system services.
Obvious benefits:
What information can we retrieve from dumpsys shell command and how we can use it
If you run dumpsys you would see a ton of system information. But you can use only separate parts of this big dump.
to see all of the "subcommands" of dumpsys do:
dumpsys | grep "DUMP OF SERVICE"
Output:

dumpsys is ultimately flexible and useful tool!
If you want to use this tool do not forget to add permission into your android manifest automatically android.permission.DUMP
Try to test all commands to learn more about dumpsys. Happy dumping!
ADB and driver versions matter. The newer the device, the lower the chances of an older version ADB to work correctly.
Apps using their own ADB copy need to be updated or at least have their ADB updated manually.
When installing Helium / Carbon for instance, it uses an old / incomplete ADB. Newer devices might not link to the ADB server for this very reason.
What I'm writing here should work for any future devices on Windows and possibly *nix OSes.
First the systems must be prepared. on Android:
in Windows:
Once these steps are/were previously done correctly, adb must be tested. If Android SDK was installed previously, open a command prompt where adb.exe is and test the listing of the device.
adb start-server IMPORTANT NOTE: This command will prompt the device to allow the communication between the computer it's been linked to on the first run. The prompt will also list an RSA key specific to the PC in question. Without this prompt on start-server, ADB will NOT work! Nor will any application relying on ADB.
adb devices Must list the device(s). If the list is empty, and most likely the RSA prompt did not occur, then no communication will work. If the list is empty the current ADB (and SDK) must be updated or installed fresh (in the case of apps bringing in their own ADB runtime, like Helium / Carbon).
In the case of applications that do bring their own ADB, if the version is old, and these apps insist in using it instead of the SDK one, these files need to be replaced with the latest ones from Android SDK. Plain and simple copy & paste.
As for Android SDK, the only required packages to be installed are SDK Tools and Platform-tools. There, ADB.exe will need some support libraries, on Windows these files are AdbWinApi.dll and AdbWinUsbApi.dll. After all is done, the SDK can be uninstalled from SDK Manager while being able to retain the ADB tool if this is the only runtime used, depending on the case in question.
If you are not able to find platform-tools folder, please open SDK Manager and install "Android SDK Platform-Tools" from SDK Tools tab.
do adb pull \sdcard\log.txt C:Users\admin\Desktop
I had a similar problem, and none of the previous solutions worked for me, and I've just solved it by myself (after a few hours of frustration), so I'm going to share my solution.
My computer suddenly stopped recognizing any Android device I've plugged in after it installed Android Composite ADB Interface for my Nexus 4. I was not able to uninstall the driver, because any attempt to do so by Device Manager was unsuccessful (Device Manager stopped responding every time).
So I've solved it this way:
Inorder to find an app's name (application label), you need to do the following:
(as shown in other answers)
aapt
command, find the app label.But devices don't ship with the aapt
binary out-of-the-box.
So you will need to install it first. You can download it from here:
https://github.com/Calsign/APDE/tree/master/APDE/src/main/assets/aapt-binaries
Check this guide for complete steps:
How to find an app name using package name through ADB Android?
(Disclaimer: I am the author of that blog post)
I had this issue on one of my development machines (all run windows 7 x64) while all other machines' adb work normally. The reason I ran into this issue is I have an old version of adb.exe reside in %android-sdk%\tools while newer Android SDKs have adb.exe under %android-sdk%\platform-tools
remove the older adb.exe from %android-sdk%\tools and add %android-sdk%\platform-tools to %PATH% solves this issue
or more generally, hunt down any adb executable in your path that are out of date, just use the latest one provided with Android SDK
To get all IPs (WIFI and data SIM) even on a non-rooted phone in 2019 use:
adb shell ip -o a
The output looks like:
1: lo inet 127.0.0.1/8 scope host lo\ valid_lft forever preferred_lft forever
1: lo inet6 ::1/128 scope host \ valid_lft forever preferred_lft forever
3: dummy0 inet6 fe80::489c:2ff:fe4a:00005/64 scope link \ valid_lft forever preferred_lft forever
11: rmnet_data1 inet6 fe80::735d:50fb:2e2:0000/64 scope link \ valid_lft forever preferred_lft forever
21: r_rmnet_data0 inet6 fe80::e38:ce2a:523a:0000/64 scope link \ valid_lft forever preferred_lft forever
30: wlan0 inet 192.168.178.0/24 brd 192.168.178.255 scope global wlan0\ valid_lft forever preferred_lft forever
30: wlan0 inet6 fe80::c2ee:fbff:fe4a:0000/64 scope link \ valid_lft forever preferred_lft forever
You can connect either through adb shell or run the comman ip -o a
directly in a terminal emulator. Again, no root required.
So I was getting this problem and found that a process called dcb was running an older version of adb. So I renamed the folder /usr/local/var/dcb to /usr/local/var/OLDdcb and it was recreated automatically and I was able to successfully run my tests in the emulator.
Another option is if windows updates are turned totally off on your PC. In this case even if you download the USB driver & try update it manually as described above it will not work. The only way in this case is enabling windows updating drivers automatically. Once you enabled this, remove the non-working driver from device manager & connect you tablet to the PC via USB cable. The drivers will be automatically downloaded & installed by Windows. This way worked on my Windows 7 PC.
If you have enabled Developer Options and USB Debugging for a Nexus, the win-usb supposedly works.
One tell-tale sign whether your driver is right is if it's got ADB in the name in Device Manager.
For my Galaxy line, I had a driver installed, but it wasn't the ADB driver.
For many non-Nexus Androids, the win-usb driver will not work. Instead, you will need to install one of the OEM drivers: https://developer.android.com/studio/run/oem-usb.html
This finally got me an ADB compatible driver, and after switching to PTP adb finally was able to find my device.
Android comes with an input
command-line tool that can simulate miscellaneous input events. To simulate tapping, it's:
input tap x y
You can use the adb shell ( > 2.3.5) to run the command remotely:
adb shell input tap x y
Tried all the above, the last piece missing was to enable USB Debugging within Developer Options which was hidden on my 4.4 Galaxy Note 10.1.
See item 5.2 from this link.
Click Revoke USB debugging authorization in Developer option and try it again.
If you use the Logcat display inside the 'debug' perspective in Eclipse the lines are colour-coded. It's pretty easy to find what made your app crash because it's usually in red.
The Java (or Dalvik) virtual machine should never crash, but if your program throws an exception and does not catch it the VM will terminate your program, which is the 'crash' you are seeing.
In Android Studio, Click on 'Tools' on the top tab bar of android studio
Tools >> Android >> SDK Manager >> Launch Standalone Sdk manager
there you can clearly see which platform tool is missing , then just install that and your adb will start working properly.In Image You Can see every thing
We can solve this issue so easily.
cd <platform-tools directory>
adb kill-server

in the command promptCould it be a problem with past preview versions of Android Studio ? nowadays "beta" has replaced the "preview". I try it out step by step debugging while using Memory Monitor at same time by Android Studio (Beta) 0.8.11 on OSX 10.9.5 without any problems.
The tutorial Debugging with Android Studio also helps, specially this paragraph :
Here a couple of screenshot while debugging step by step on a breakpoint a monitoring the memory on the emulator:
The comparison needs to be evaluated fully inside EL ${ ... }
, not outside.
<c:if test="${values.type eq 'object'}">
As to the docs, those ${}
things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.
<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />
By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass()
and then Class#getSimpleName()
instead of adding a custom getter.
<c:forEach items="${list}" var="value">
<c:if test="${value['class'].simpleName eq 'Object'}">

I have just sent an email with gmail through Python. Try to use smtplib.SMTP_SSL to make the connection. Also, you may try to change the gmail domain and port.
So, you may get a chance with:
server = smtplib.SMTP_SSL('smtp.googlemail.com', 465)
server.login(gmail_user, password)
server.sendmail(gmail_user, TO, BODY)
As a plus, you could check the email builtin module. In this way, you can improve the readability of you your code and handle emails headers easily.
Check your application's respective Application Framework Pool - it could be stopped. If it is, start it and check again.
If you're still experiencing issues you can also check out Event Viewer to find the cause of that error in order to troubleshoot more.
As of May 2017, multiple FROM
s can be used in a single Dockerfile.
See "Builder pattern vs. Multi-stage builds in Docker" (by Alex Ellis) and PR 31257 by Tõnis Tiigi.
The general syntax involves adding
FROM
additional times within your Dockerfile - whichever is the lastFROM
statement is the final base image. To copy artifacts and outputs from intermediate images useCOPY --from=<base_image_number>
.
FROM golang:1.7.3 as builder
WORKDIR /go/src/github.com/alexellis/href-counter/
RUN go get -d -v golang.org/x/net/html
COPY app.go .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o app .
FROM alpine:latest
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=builder /go/src/github.com/alexellis/href-counter/app .
CMD ["./app"]
The result would be two images, one for building, one with just the resulting app (much, much smaller)
REPOSITORY TAG IMAGE ID CREATED SIZE
multi latest bcbbf69a9b59 6 minutes ago 10.3MB
golang 1.7.3 ef15416724f6 4 months ago 672MB
what is a base image?
A set of files, plus EXPOSE
'd ports, ENTRYPOINT
and CMD
.
You can add files and build a new image based on that base image, with a new Dockerfile
starting with a FROM
directive: the image mentioned after FROM
is "the base image" for your new image.
does it mean that if I declare
neo4j/neo4j
in aFROM
directive, that when my image is run the neo database will automatically run and be available within the container on port 7474?
Only if you don't overwrite CMD
and ENTRYPOINT
.
But the image in itself is enough: you would use a FROM neo4j/neo4j
if you had to add files related to neo4j
for your particular usage of neo4j
.
Slightly more compact:
df = pd.DataFrame([1, 2, 3, 4, 5], index=[100, 29, 234, 1, 150], columns=['A'])
df = df.sort_index()
print(df)
Note:
sort
has been deprecated, replaced by sort_index
for this scenarioinplace
as it is usually harder to read and prevents chaining. See explanation in answer here:
Pandas: peculiar performance drop for inplace rename after dropnaIt looks like the problem is request to server is not a multi-part request. Basically you need to modify your client-side form. For example:
<form action="..." method="post" enctype="multipart/form-data">
<input type="file" name="file" />
</form>
Hope this helps.
I am aware there are existing answers which solves the problem. For those who are new to git, As of 02/11/2021, The default branch in git is "main"
not "master"
branch, The command will be
git push -u origin main
If you just want to initialize outside of any method then use the initializer blocks :
import java.util.ArrayList;
public class Test {
private ArrayList<String> symbolsPresent = new ArrayList<String>();
// All you need is this block.
{
symbolsPresent = new ArrayList<String>();
symbolsPresent.add("ONE");
symbolsPresent.add("TWO");
symbolsPresent.add("THREE");
symbolsPresent.add("FOUR");
}
public ArrayList<String> getSymbolsPresent() {
return symbolsPresent;
}
public void setSymbolsPresent(ArrayList<String> symbolsPresent) {
this.symbolsPresent = symbolsPresent;
}
public static void main(String args[]) {
Test t = new Test();
System.out.println("Symbols Present is" + t.symbolsPresent);
}
}
Below Algo "compare two strings lexicographically"
Input two strings string 1 and string 2.
for (int i = 0; i < str1.length() && i < str2.length(); i ++)
(Loop through each character of both strings comparing them until one of the string terminates):
a. If unicode value of both the characters is same then continue;
b. If unicode value of character of string 1 and unicode value of string 2 is different then return (str1[i]-str2[i])
if length of string 1 is less than string2
return str2[str1.length()]
else
return str1[str2.length()]
// This method compares two strings lexicographically
public static int compareCustom(String s1, String s2) {
for (int i = 0; i < s1.length() && i< s2.length(); i++) {
if(s1.charAt(i) == s2.charAt(i)){
//System.out.println("Equal");
continue;

Here's some code I use to deal with this.
First we show the element, which will typically set the display type to "block" via .show() function, and then set the CSS rule to "visible":
jQuery( '.element' ).show().css( 'visibility', 'visible' );
Or, assuming that the class that is hiding the element is called hidden, such as in Twitter Bootstrap, toggleClass() can be useful:
jQuery( '.element' ).toggleClass( 'hidden' );
Lastly, if you want to chain functions, perhaps with fancy with a fading effect, you can do it like so:
jQuery( '.element' ).css( 'visibility', 'visible' ).fadeIn( 5000 );
Just do nothing once the criteria is met, otherwise do the processing you require and the For
loop will go to the next item.
For i = 2 To 24
Level = Cells(i, 4)
Return = Cells(i, 5)
If Return = 0 And Level = 0 Then
'Do nothing
Else
'Do something
End If
Next i
Or change the clause so it only processes if the conditions are met:
For i = 2 To 24
Level = Cells(i, 4)
Return = Cells(i, 5)
If Return <> 0 Or Level <> 0 Then
'Do something
End If
Next i
IMHO I think that all the models have a great place but the problem I have with the model first approach is in many large businesses with DBA's controlling the databases you do not get the flexibility of building applications without using database first approaches. I have worked on many projects and when it came to deployment they wanted full control.
So as much as I agree with all the possible variations Code First, Model First, Database first, you must consider the actual production environment. So if your system is going to be a large user base application with many users and DBA's running the show then you might consider the Database first option just my opinion.
Also be careful how you execute the js on the page. For example if you do something like this:
(function(window, document, undefined){
var foo = document.getElementById("foo");
console.log(foo);
})(window, document, undefined);
This will return null because you'd be calling the document before it was loaded.
Better option..
(function(window, document, undefined){
// code that should be taken care of right away
window.onload = init;
function init(){
// the code to be called when the dom has loaded
// #document has its nodes
}
})(window, document, undefined);
The simplest way to do that is by opening the certificate store you want and then using X509Certificate2UI
.
var store = new X509Store(StoreName.My, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly);
var selectedCertificate = X509Certificate2UI.SelectFromCollection(
store.Certificates,
"Title",
"MSG",
X509SelectionFlag.SingleSelection);
More information in X509Certificate2UI

tl;dr:
concat
and append
currently sort the non-concatenation index (e.g. columns if you're adding rows) if the columns don't match. In pandas 0.23 this started generating a warning; pass the parameter sort=True
to silence it. In the future the default will change to not sort, so it's best to specify either sort=True
or False
now, or better yet ensure that your non-concatenation indices match.
The warning is new in pandas 0.23.0:
In a future version of pandas pandas.concat()
and DataFrame.append()
will no longer sort the non-concatenation axis when it is not already aligned. The current behavior is the same as the previous (sorting), but now a warning is issued when sort is not specified and the non-concatenation axis is not aligned,
link.
More information from linked very old github issue, comment by smcinerney :
When concat'ing DataFrames, the column names get alphanumerically sorted if there are any differences between them. If they're identical across DataFrames, they don't get sorted.
This sort is undocumented and unwanted. Certainly the default behavior should be no-sort.
After some time the parameter sort
was implemented in pandas.concat
and DataFrame.append
:
sort : boolean, default None
Sort non-concatenation axis if it is not already aligned when join is 'outer'. The current default of sorting is deprecated and will change to not-sorting in a future version of pandas.
Explicitly pass sort=True to silence the warning and sort. Explicitly pass sort=False to silence the warning and not sort.
This has no effect when join='inner', which already preserves the order of the non-concatenation axis.
So if both DataFrames have the same columns in the same order, there is no warning and no sorting:
df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['a', 'b'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])
print (pd.concat([df1, df2]))
a b
0 1 0
1 2 8
0 4 7
1 5 3
df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['b', 'a'])
print (pd.concat([df1, df2]))
b a
0 0 1
1 8 2
0 7 4
1 3 5
But if the DataFrames have different columns, or the same columns in a different order, pandas returns a warning if no parameter sort
is explicitly set (sort=None
is the default value):
df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8]}, columns=['b', 'a'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3]}, columns=['a', 'b'])
print (pd.concat([df1, df2]))
FutureWarning: Sorting because non-concatenation axis is not aligned.
a b
0 1 0
1 2 8
0 4 7
1 5 3
print (pd.concat([df1, df2], sort=True))
a b
0 1 0
1 2 8
0 4 7
1 5 3
print (pd.concat([df1, df2], sort=False))
b a
0 0 1
1 8 2
0 7 4
1 3 5
If the DataFrames have different columns, but the first columns are aligned - they will be correctly assigned to each other (columns a
and b
from df1
with a
and b
from df2
in the example below) because they exist in both. For other columns that exist in one but not both DataFrames, missing values are created.
Lastly, if you pass sort=True
, columns are sorted alphanumerically. If sort=False
and the second DafaFrame has columns that are not in the first, they are appended to the end with no sorting:
df1 = pd.DataFrame({"a": [1, 2], "b": [0, 8], 'e':[5, 0]},
columns=['b', 'a','e'])
df2 = pd.DataFrame({"a": [4, 5], "b": [7, 3], 'c':[2, 8], 'd':[7, 0]},

@Service
@Transactional
public class MyServiceImpl implements MyService{

From similar question DB2 - find and compare the lentgh of the value in a table field - add RTRIM since LENGTH will return length of column definition. This should be correct:
select * from table where length(RTRIM(fieldName))=10
UPDATE 27.5.2019: maybe on older db2 versions the LENGTH function returned the length of column definition. On db2 10.5 I have tried the function and it returns data length, not column definition length:
select fieldname
, length(fieldName) len_only
, length(RTRIM(fieldName)) len_rtrim
from (values (cast('1234567890 ' as varchar(30)) ))
as tab(fieldName)
FIELDNAME LEN_ONLY LEN_RTRIM
------------------------------ ----------- -----------
1234567890 12 10
One can test this by using this term:
where length(fieldName)!=length(rtrim(fieldName))
git branch --contains <ref>
is the most obvious "porcelain" command to do this. If you want to do something similar with only "plumbing" commands:
COMMIT=$(git rev-parse <ref>) # expands hash if needed
for BRANCH in $(git for-each-ref --format "%(refname)" refs/heads); do
if $(git rev-list $BRANCH | fgrep -q $COMMIT); then
echo $BRANCH
fi
done
(crosspost from this SO answer)
Git. Switch to another branch
git checkout branch_name
set WRAP OFF
set PAGESIZE 0
Try using those settings.
You can use Pandas library to read the first few lines from the huge dataset.
import pandas as pd
data = pd.read_csv("names.csv", nrows=1)
You can mention the number of lines to be read in the nrows parameter.
@Navaneeth and @Antfish, no need to transform you can do like this also because in above solution only top border is visible so for inside curve you can use bottom border.
.box {_x000D_
width: 500px;_x000D_
height: 100px;_x000D_
border: solid 5px #000;_x000D_
border-color: transparent transparent #000 transparent;_x000D_
border-radius: 0 0 240px 50%/60px;_x000D_
}
_x000D_
<div class="box"></div>

Try the JSON Parser by Douglas Crockford at github. You can then simply create a JSON object out of your String variable as shown below:
var JSONText = '{"c":{"a":[{"name":"cable - black","value":2},{"name":"case","value":2}]},"o":{"v":[{"name":"over the ear headphones - white/purple","value":1}]},"l":{"e":[{"name":"lens cleaner","value":1}]},"h":{"d":[{"name":"hdmi cable","value":1},{"name":"hdtv essentials (hdtv cable setup)","value":1},{"name":"hd dvd \u0026 blue-ray disc lens cleaner","value":1}]}'
var JSONObject = JSON.parse(JSONText);
var c = JSONObject["c"];
var o = JSONObject["o"];
You can try this:
sales['time_hour'] = pd.to_datetime(sales['timestamp']).dt.hour
I had the same problem, It was solved when I checked the below checkbox
Include externals
Did you try using the -ArgumentList
parameter:
invoke-command -ComputerName studio -ScriptBlock { param ( $myarg ) ping.exe $myarg } -ArgumentList localhost
http://technet.microsoft.com/en-us/library/dd347578.aspx
An example of invoking a program that is not in the path and has a space in it's folder path:
invoke-command -ComputerName Computer1 -ScriptBlock { param ($myarg) & 'C:\Program Files\program.exe' -something $myarg } -ArgumentList "myArgValue"
If the value of the argument is static you can just provide it in the script block like this:
invoke-command -ComputerName Computer1 -ScriptBlock { & 'C:\Program Files\program.exe' -something "myArgValue" }
The jquery colortip plugin also supports <br>
tags in the title attribute, you might want to look into that one.
No one seems to understand that a retail Nexus One even after being rooted still will not let you browse the file system using DDMS File Explorer. We are talking about real phones here and not the emulator. If you happen to have a Nexus One Developer Phone you can browse the file system using DDMS Filer Explorer, but a retail Nexus One that has been rooted you can't. Got it?
So I hope that answers the question of not being able to use the DDMS File Explorer to browse the file system of a rooted retail Nexus One. After rooting a retail Nexus One there is still something that remains to be done to use DDMS to use the File Explorer to browse the phones File System. I don't know what it is. Maybe someone else knowns.
If you don't want to install extensions, you can simply prepend the URL with view-source:
, e.g. view-source:http://content.dimestore.com/prod/survey_data/4535/4535.json
. This usually works in Firefox and Chrome (will still offer to download the file however if Content-Disposition: attachment
header is present).
The commit should be present in your local, check by using git log
.
If the commit is not present then try git fetch
to update the local with the latest remote.
set identity_insert customer on
insert into Customer(id,Name,city,Salary) values(8,'bcd','Amritsar',1234)

I use ­
, inserted manually where necessary.
I always find it a pity that people don’t use techniques because there is some—maybe old or strange—browser around which doesn’t handle them the way they were specified. I found that ­
is working properly in both recent Internet Explorer and Firefox browsers, that should be enough. You may include a browser check telling people to use something mature or continue at their own risk if they come around with some strange browser.
Syllabification isn’t that easy and I cannot recommend leaving it to some Javascript. It’s a language specific topic and may need to be carefully revised by the deskman if you don’t want it to turn your text irritating. Some languages, such as German, form compound words and are likely to lead to decomposition problems. E.g. Spargelder
(germ. saved money, pl.) may, by syllabification rules, be wrapped in two places (Spar-gel-der
). However, wrapping it in the second position, turns the first part to show up as Spargel-
(germ. asparagus), activating a completely misleading concept in the head of the reader and therefore shoud be avoided.
And what about the string Wachstube
? It could either mean ‘guardroom’ (Wach-stu-be
) or ‘tube of wax’ (Wachs-tu-be
). You may probably find other examples in other languages as well. You should aim to provide an environment in which the deskman can be supported in creating a well-syllabified text, proof-reading every critical word.
Your JSON-data contains the property Data
, but you're accessing data
. It's case sensitive
function jsonparser1() {
$.ajax({
type: "GET",
url: "http://10.211.2.219:8080/SampleWebService/sample.do",
dataType: "json",
success: function (xml) {
alert(xml.Data[0].City);
result = xml.Code;
document.myform.result1.value = result;
},
});
}
EDIT Also City and Code is in the wrong case. (Thanks @Christopher Kenney)
EDIT2 It should also be json, and not jsonp (at least in this case)
UPDATE According to your latest comment, you should read this answer: https://stackoverflow.com/a/11736771/325836 by Abdul Munim
The Web Site project is compiled on the fly. You end up with a lot more DLL files, which can be a pain. It also gives problems when you have pages or controls in one directory that need to reference pages and controls in another directory since the other directory may not be compiled into the code yet. Another problem can be in publishing.
If Visual Studio isn't told to re-use the same names constantly, it will come up with new names for the DLL files generated by pages all the time. That can lead to having several close copies of DLL files containing the same class name, which will generate plenty of errors. The Web Site project was introduced with Visual Studio 2005, but it has turned out not to be popular.
The Web Application Project was created as an add-in and now exists as part of SP 1 for Visual Studio 2005. The main differences are the Web Application Project was designed to work similarly to the Web projects that shipped with Visual Studio 2003. It will compile the application into a single DLL file at build time. To update the project, it must be recompiled and the DLL file published for changes to occur.
Another nice feature of the Web Application project is it's much easier to exclude files from the project view. In the Web Site project, each file that you exclude is renamed with an excluded keyword in the filename. In the Web Application Project, the project just keeps track of which files to include/exclude from the project view without renaming them, making things much tidier.
The article ASP.NET 2.0 - Web Site vs Web Application project also gives reasons on why to use one and not the other. Here is an excerpt of it:
- You need to migrate large Visual Studio .NET 2003 applications to VS 2005? use the Web Application project.
- You want to open and edit any directory as a Web project without creating a project file? use Web Site project.
- You need to add pre-build and post-build steps during compilation? use Web Application project.
- You need to build a Web application using multiple Web projects? use the Web Application project.
- You want to generate one assembly for each page? use the Web Site project.
- You prefer dynamic compilation and working on pages without building entire site on each page view? use Web Site project.
- You prefer single-page code model to code-behind model? use Web Site project.
Web Application Projects versus Web Site Projects (MSDN) explains the differences between the web site and web application projects. Also, it discusses the configuration to be made in Visual Studio.
It seems like you can also use the patch command. Put the diff in the root of the repository and run patch
from the command line.
patch -i yourcoworkers.diff
or
patch -p0 -i yourcoworkers.diff
You may need to remove the leading folder structure if they created the diff without using --no-prefix
.
If so, then you can remove the parts of the folder that don't apply using:
patch -p1 -i yourcoworkers.diff
The -p(n) signifies how many parts of the folder structure to remove.
More information on creating and applying patches here.
You can also use
git apply yourcoworkers.diff --stat
to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).
use this too :
if(e.preventDefault)
e.preventDefault();
else
e.returnValue = false;
Becoz e.preventDefault() is not supported in IE( some versions ). In IE it is e.returnValue = false
I am new to .NET/MVC programming, but my understanding is that the Site.css file (under the Content folder in MVC) is a site-level override for Bootstrap CSS, allowing you to override bootstrap native settings in a portable and non-destructive manner (e.g. you can easily save and reapply your site.css changes when updating Bootstrap on your system.)
In Bootstrap 3.0.0, Site.css has the following style setting:
/* Set width on the form input elements since they're 100% wide by default */
input,
select,
textarea {
max-width: 280px;
}
Other blogs have suggested that this 280px width was added in haste near a release date, in a desire to make the UI look better than it does with 100% width input. Fortunately it was placed in a "visible" location in the site file so you would notice it.
Simply change the width setting, either for all three input types, or pull out textarea and give it its own setting if you want to leave the others alone.
Did something like that once:
CREATE TABLE exclusions(excl VARCHAR(250));
INSERT INTO exclusions(excl)

('%timeline%'),
('%Placeholders%'),
('%Stages%'),
('%master_stage_1205x465%'),
('%Accessories%'),
('%chosen-sprite.png'),
('%WebResource.axd');
GO
CREATE VIEW ToBeDeleted AS

WHERE lf.file_id NOT IN
(
SELECT DISTINCT
lf.file_id
FROM LargeFiles lf
LEFT JOIN exclusions e ON(lf.URL LIKE e.excl)
WHERE e.excl IS NULL
)
);
GO
CHECKPOINT
GO
SET NOCOUNT ON;
DECLARE @r INT;
SET @r = 1;
WHILE @r>0
BEGIN
DELETE TOP (10000) FROM ToBeDeleted;
SET @r = @@ROWCOUNT
END

Here we can use urllib's Legacy interface in Python3:
The following functions and classes are ported from the Python 2 module urllib (as opposed to urllib2). They might become deprecated at some point in the future.
Example (2 lines code):
import urllib.request
url = 'https://www.python.org/static/img/python-logo.png'
urllib.request.urlretrieve(url, "logo.png")
Add Delegate : UITextFieldDelegate
@interface ViewController : UIViewController <UITextFieldDelegate>
and then add this delegate method
// This should work perfectly
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
setTimeout() function it's use to delay a process in JavaScript.
w3schools has an easy tutorial about this function.
The same can be done with Lock interface:
import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;
public class NumberPrinter implements Runnable {
private Lock lock;
private Condition condition;
private String type;
private static boolean oddTurn = true;
public NumberPrinter(String type, Lock lock, Condition condition) {
this.type = type;
this.lock = lock;
this.condition = condition;
}
public void run() {
int i = type.equals("odd") ? 1 : 2;
while (i <= 10) {
if (type.equals("odd"))
printOdd(i);
if (type.equals("even"))
printEven(i);
i = i + 2;
}
}
private void printOdd(int i) {
// synchronized (lock) {
lock.lock();
while (!oddTurn) {
try {
// lock.wait();
condition.await();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
System.out.println(type + " " + i);
oddTurn = false;
// lock.notifyAll();
condition.signalAll();
lock.unlock();
}
// }
private void printEven(int i) {
// synchronized (lock) {
lock.lock();
while (oddTurn) {
try {
// lock.wait();
condition.await();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
System.out.println(type + " " + i);
oddTurn = true;
// lock.notifyAll();
condition.signalAll();
lock.unlock();
}
// }
public static void main(String[] args) {
Lock lock = new ReentrantLock();
Condition condition = lock.newCondition();
Thread odd = new Thread(new NumberPrinter("odd", lock, condition));
Thread even = new Thread(new NumberPrinter("even", lock, condition));
odd.start();
even.start();
}
}
Date Casting for Laravel 6.x and 7.x
/**
* The attributes that should be cast.
*
* @var array
*/
protected $casts = [
'created_at' => 'datetime:Y-m-d',
'updated_at' => 'datetime:Y-m-d',
'deleted_at' => 'datetime:Y-m-d h:i:s'
];
It easy for Laravel 5 in your Model add property protected $dates = ['created_at', 'cached_at']
. See detail here https://laravel.com/docs/5.2/eloquent-mutators#date-mutators
Date Mutators: Laravel 5.x
namespace App;
use Illuminate\Database\Eloquent\Model;
class User extends Model
{
/**
* The attributes that should be mutated to dates.
*
* @var array
*/
protected $dates = ['created_at', 'updated_at', 'deleted_at'];
}
You can format date like this $user->created_at->format('M d Y');
or any format that support by PHP.
The universal adb driver installer worked for me. I went from an HTC to a Samsung to a LG Nexus. The drivers are all over the place for me.
You can use shorthand syntax as of Twig 1.12.0
{{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
{{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}
Just in case anyone wants to, IMHO the best solution using CSS is by a flexbox.
Here is an example:
.kw-dvp-HorizonalButton {_x000D_
color: #0078d7;_x000D_
display:flex;_x000D_
flex-wrap:nowrap;_x000D_
align-items:center;_x000D_
}_x000D_
.kw-dvp-HorizonalButton:before, .kw-dvp-HorizonalButton:after {_x000D_
background-color: #0078d7;_x000D_
content: "";_x000D_
display: inline-block;_x000D_
float:left;_x000D_
height:1px;_x000D_
}_x000D_
.kw-dvp-HorizonalButton:before {_x000D_
order:1;_x000D_
flex-grow:1;_x000D_
margin-right:8px;_x000D_
}_x000D_
.kw-dvp-HorizonalButton:after {_x000D_
order: 3;_x000D_
flex-grow: 1;_x000D_
margin-left: 8px;_x000D_
}_x000D_
.kw-dvp-HorizonalButton * {_x000D_
order: 2;_x000D_
}
_x000D_
<div class="kw-dvp-HorizonalButton">_x000D_
<span>hello</span>_x000D_
</div>
_x000D_
This should always result in a perfectly centered aligned content with a line to the left and right, with an easy to control margin between the line and your content.
It creates a line element before and after your top control and set them to order 1,3 in your flex container while setting your content as order 2 (go in the middle). giving the before/after a grow of 1 will make them consume the most vacant space equally while keeping your content centered.
Hope this helps!
You can also relax your CSP for styles by adding style-src 'self' 'unsafe-inline';
"content_security_policy": "default-src 'self' style-src 'self' 'unsafe-inline';"
This will allow you to keep using inline style in your extension.
As others have pointed out, this is not recommended, and you should put all your CSS in a dedicated file. See the OWASP explanation on why CSS can be a vector for attacks (kudos to @ KayakinKoder for the link).
Use CONCAT_WS instead:
CONCAT_WS() does not skip empty strings. However, it does skip any NULL values after the separator argument.
SELECT CONCAT_WS('-',`affiliate_name`,`model`,`ip`,`os_type`,`os_version`) AS device_name FROM devices
To summarise some of the current options for traversing/filtering JSON data, and provide some syntax examples...
JSPath
.automobiles{.maker === "Honda" && .year > 2009}.model
json:select() (inspired more by CSS selectors)
.automobiles .maker:val("Honda") .model
JSONPath (inspired more by XPath)
$.automobiles[?(@.maker='Honda')].model
I think JSPath looks the nicest, so I'm going to try and integrate it with my AngularJS + CakePHP app.
(I originally posted this answer in another thread but thought it would be useful here, also.)
A very simple example is that if you have a UserService
that has @Autowired
jpa resposiroty UserRepository
...
class UserService{
@Autowired
UserRepository userRepository;
...
}
then in the test class for UserService
you will do
...
class TestUserService{
@Mock
UserRepository userRepository;
@InjectMocks
UserService userService;
...
}
@InjectMocks
tells the framework that take the @Mock UserRepository userRespository;
and inject that into userService
so rather than auto wiring a real instance of UserRepository
a Mock of UserRepository
will be injected in userService
.
Here's an approach using the URL() interface:
new URL(location.pathname, location.href).href
A list comprehension is a simple approach:
j2 = [x for x in j if x >= 5]
Alternately, you can use filter
for the exact same result:
j2 = filter(lambda x: x >= 5, j)
Note that the original list j
is unmodified.
OK I was able to solve this myself:
$(document).ready(function() {
$('#tid_css').DataTable({
"iDisplayLength": 100,
"bFilter": false,
"aaSorting": [
[2, "desc"]
],
"fnRowCallback": function(nRow, aData, iDisplayIndex, iDisplayIndexFull) {
if (aData[2] == "5") {
$('td', nRow).css('background-color', 'Red');
} else if (aData[2] == "4") {
$('td', nRow).css('background-color', 'Orange');
}
}
});
})
You can do this:
And to capture locale. You can do this:
private static final String LOCALE = LocaleContextHolder.getLocale().getLanguage()
+ "-" + LocaleContextHolder.getLocale().getCountry();
You should use htmlspecialchars
. It replaces characters as below:
&
(ampersand) becomes &
"
(double quote) becomes "
when ENT_NOQUOTES is not set.'
(single quote) becomes '
only when ENT_QUOTES is set.<
(less than) becomes <
>
(greater than) becomes >
This will clean the caches used to store bundle dependency resolution and eclipse extension registry data. Using this option will force eclipse to reinitialize these caches.
eclipse -clean
You can use Chr(13). Then just wrap the whole thing in Chr(34). Chr(34) is double quotes.
Not sure if this help or not but this is a command line tool which let you simply send test mails from a SMTP server priodically. http://code.google.com/p/woodpecker-tester/
Simply use CAST,
CAST(column_name AS UNSIGNED)
The type for the cast result can be one of the following values:
BINARY[(N)]
CHAR[(N)]
DATE
DATETIME
DECIMAL[(M[,D])]
SIGNED [INTEGER]
TIME
UNSIGNED [INTEGER]
You can use pandas dataframes or series as Julien said but if you want to restrict your-self to numpy you can pass an additional array of indices:
from sklearn.model_selection import train_test_split
import numpy as np
n_samples, n_features, n_classes = 10, 2, 2
data = np.random.randn(n_samples, n_features) # 10 training examples
labels = np.random.randint(n_classes, size=n_samples) # 10 labels
indices = np.arange(n_samples)
x1, x2, y1, y2, idx1, idx2 = train_test_split(
data, labels, indices, test_size=0.2)
In my case I need to do
sudo npm install
my project is inside /var/www so I also need to set proper permissions.
ini_set('magic_quotes_runtime', 0)
I guess.
This is how I do it...
public class ThreadA {
public ThreadA(object[] args) {
...
}
public void Run() {
while (true) {
Thread.sleep(1000); // wait 1 second for something to happen.
doStuff();
if(conditionToExitReceived) // what im waiting for...
break;
}
//perform cleanup if there is any...
}
}
Then to run this in its own thread... ( I do it this way because I also want to send args to the thread)
private void FireThread(){
Thread thread = new Thread(new ThreadStart(this.startThread));
thread.start();
}
private void (startThread){
new ThreadA(args).Run();
}
The thread is created by calling "FireThread()"
The newly created thread will run until its condition to stop is met, then it dies...
You can signal the "main" with delegates, to tell it when the thread has died.. so you can then start the second one...
Best to read through : This MSDN Article
I would do something like the following:
INSERT INTO cache VALUES (key, generation)
ON DUPLICATE KEY UPDATE (key = key, generation = generation + 1);
Setting the generation value to 0 in code or in the sql but the using the ON DUP... to increment the value. I think that's the syntax anyway.
Every time you use html syntax you have to start the next razor statement with a @. So it should be @if ....
There is a better way to do this:
If the array $arr_options contains the existing array.
$arr_new_input['name'] = [
'type' => 'text',
'label' => 'First name',
'show' => true,
'required' => true
];
$arr_options += $arr_new_input;
Warning: $arr_options must exist. if $arr_options already has a ['name'] it wil be overwritten.
Hope this helps.

Adapting the PATH
should work. Just tried on my Git bash:
$ python --version
sh.exe": python: command not found
$ PATH=$PATH:/c/Python27/
$ python --version
Python 2.7.6
In particular, only provide the directory; don't specify the .exe
on the PATH
; and use slashes.
The string in quotes after "[submodule" doesn't matter. You can change it to "foobar" if you want. It's used to find the matching entry in ".git/config".
Therefore, if you make the change before you run "git submodule init", it'll work fine. If you make the change (or pick up the change through a merge), you'll need to either manually edit .git/config or run "git submodule init" again. If you do the latter, you'll be left with a harmless "stranded" entry with the old name in .git/config.
With Jeffrey Fox's interpretation about no-cache
, i've tested under chrome 52.0.2743.116 m, the result shows that no-cache
has the same behavior as must-revalidate
, they all will NOT use local cache when server is unreachable, and, they all will use cache while tap browser's Back/Forward button when server is unreachable.
As above, i think max-age=0, must-revalidate
is identical to no-cache
, at least in implementation.
Open "localhost:8080" on your browser and see what is running on this port.
I did it and I just found Oracle 10g XE running on background, so I went to start->Services and stopped all oracle services. Then I redo mvnw spring-boot:run
on IntelliJ and it runs like magic.
What you are looking for is this:
SHOW VARIABLES;
You can modify it further like any query:
SHOW VARIABLES LIKE '%max%';
I just learned something new thanks to Artiso. I gave each module a name in the properties box. These names were also what I declared in the module. When I tried to call my second module, I kept getting an error: Compile error: Expected variable or procedure, not module
After reading Artiso's comment above about not having the same names, I renamed my second module, called it from the first, and problem solved. Interesting stuff! Thanks for the info Artiso!
In case my experience is unclear:
Module Name: AllFSGroupsCY Public Sub AllFSGroupsCY()
Module Name: AllFSGroupsPY Public Sub AllFSGroupsPY()
From AllFSGroupsCY()
Public Sub FSGroupsCY()
AllFSGroupsPY 'will error each time until the properties name is changed
End Sub
If you run your legacy program with ProcessBuilder, you will be able to specify its working directory.
As Nikolai has said you can use the gdb 'set' command to change the value of a variable.
You can also use the 'set' command to change memory locations. eg. Expanding on Nikolai's example:
(gdb) l
6 {
7 int i;
8 struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10
(gdb) p &i
$2 = (int *) 0xbfbb0000
(gdb) set *((int *) 0xbfbb0000) = 20
(gdb) p i
$3 = 20
This should work for any valid pointer, and can be cast to any appropriate data type.
My problem is multi modules project with base module, app module and feature module. Each module has AndroidManifest of its own, and I implemented build variant for debug and main. So we must sure that "android:name" just declared in Manifest of debug and main only, and do not set it in any of Manifest in child module. Ex: Manifest in main:
<application
android:name=".App"/>
Manifest in debug:
<application
tools:replace="android:name"
android:name=".DebugApp"
/>
Do not set "android:name" in other Manifest files like this:
<application android:name=".App">
Just define in feature module like this and it will merged fine
<application>
If you are using the image as a bullet, you might consider the :before pseudo element.
#footer ul li {
}
#footer ul li:before {
content: url(/images/arrow.png);
filter:alpha(opacity=50);
filter: progid:DXImageTransform.Microsoft.Alpha(opacity=0.5);
opacity:.50;
}
Your format specifier is incorrect. From the printf()
man page on my machine:
0
A zero '0
' character indicating that zero-padding should be used rather than blank-padding. A '-
' overrides a '0
' if both are used;Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);
Precision: An optional period, '
.
', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;
For your case, your format would be %09.3f
:
#include <stdio.h>
int main(int argc, char **argv)
{
printf("%09.3f\n", 4917.24);
return 0;
}
Output:
$ make testapp
cc testapp.c -o testapp
$ ./testapp
04917.240
Note that this answer is conditional on your embedded system having a printf()
implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.
You can also use DEV_RANDOM, where 128 = 1/2 the generated token length. Code below generates 256 token.
$token = bin2hex(mcrypt_create_iv(128, MCRYPT_DEV_RANDOM));
If you don't "care" about the data you can just do something like:
search_params = params[:search].valid_encoding? ? params[:search].gsub(/\W+/, '') : "nothing"
I just used valid_encoding?
to get passed it. Mine is a search field, and so i was finding the same weirdness over and over so I used something like: just to have the system not break. Since i don't control the user experience to autovalidate prior to sending this info (like auto feedback to say "dummy up!") I can just take it in, strip it out and return blank results.
In Rails 2, I would have written:
validates_uniqueness_of :zipcode, :scope => :recorded_at
In Rails 3:
validates :zipcode, :uniqueness => {:scope => :recorded_at}
For multiple attributes:
validates :zipcode, :uniqueness => {:scope => [:recorded_at, :something_else]}
If your button still doesn't show anything with title
, check if your button is NOT disabled
var length = $('#selected ul').children('li').length
// or the same:
var length = $('#selected ul > li').length
You probably could also omit li
in the children's selector.
See .length
.
The easiest way to do this, is to use the disabled
attribute, as you had done in your original question:
<button class="btn btn-disabled" disabled>Content of Button</button>
As of now, Twitter Bootstrap doesn't have a method to disable a button's functionality without using the disabled
attribute.
Nonetheless, this would be an excellent feature for them to implement into their javascript library.
if(doc.SelectSingleNode("//mynode")==null)....
Should do it (where doc is your XmlDocument object, obviously)
Alternatively you could use an XSD and validate against that

I'm the author of the AI program that others have mentioned in this thread. You can view the AI in action or read the source.
Currently, the program achieves about a 90% win rate running in javascript in the browser on my laptop given about 100 milliseconds of thinking time per move, so while not perfect (yet!) it performs pretty well.
Since the game is a discrete state space, perfect information, turn-based game like chess and checkers, I used the same methods that have been proven to work on those games, namely minimax search with alpha-beta pruning. Since there is already a lot of info on that algorithm out there, I'll just talk about the two main heuristics that I use in the static evaluation function and which formalize many of the intuitions that other people have expressed here.
This heuristic tries to ensure that the values of the tiles are all either increasing or decreasing along both the left/right and up/down directions. This heuristic alone captures the intuition that many others have mentioned, that higher valued tiles should be clustered in a corner. It will typically prevent smaller valued tiles from getting orphaned and will keep the board very organized, with smaller tiles cascading in and filling up into the larger tiles.
Here's a screenshot of a perfectly monotonic grid. I obtained this by running the algorithm with the eval function set to disregard the other heuristics and only consider monotonicity.
The above heuristic alone tends to create structures in which adjacent tiles are decreasing in value, but of course in order to merge, adjacent tiles need to be the same value. Therefore, the smoothness heuristic just measures the value difference between neighboring tiles, trying to minimize this count.
A commenter on Hacker News gave an interesting formalization of this idea in terms of graph theory.
Here's a screenshot of a perfectly smooth grid, courtesy of this excellent parody fork.
And finally, there is a penalty for having too few free tiles, since options can quickly run out when the game board gets too cramped.
And that's it! Searching through the game space while optimizing these criteria yields remarkably good performance. One advantage to using a generalized approach like this rather than an explicitly coded move strategy is that the algorithm can often find interesting and unexpected solutions. If you watch it run, it will often make surprising but effective moves, like suddenly switching which wall or corner it's building up against.
Here's a demonstration of the power of this approach. I uncapped the tile values (so it kept going after reaching 2048) and here is the best result after eight trials.
Yes, that's a 4096 alongside a 2048. =) That means it achieved the elusive 2048 tile three times on the same board.
While all of the other answers work, they all have one big problem: it is up to the browser to decide what to do if they encounter a Location header. Usually browser stop processing the request and redirect to the URI indicated with the Location header. But a malicious user could just ignore the Location header and continue its request. Furthermore there may be other things that cause the php interpreter to continue evaluating the script past the Location header, which is not what you intended.
Image this:
<?php
if (!logged_id()) {
header("Location:login.php");
}
delete_everything();
?>
What you want and expected is that not logged in users are redirected to the login page, so that only logged in users can delete_everything. But if the script gets executed past the Location header still everything gets deleted. Thus, it is import to ALWAYS put an exit after a Location header, like this:
<?php
if (!logged_id()) {
header("Location:login.php");
exit; // <- don't forget this!
}
delete_everything();
?>
So, to answer your question: to redirect from a php page to another page (not just php, you can redirect to any page this way), use this:
<?php
header("Location:http://www.example.com/some_page.php");
exit; // <- don't forget this!
?>
Small note: the HTTP standard says that you must provide absolute URLs in the Location header (http://... like in my example above) even if you just want to redirect to another file on the same domain. But in practice relative URLs (Location:some_page.php) work in all browsers, though not being standard compliant.
You manage the list of available compilers in the Window -> Preferences -> Java -> Installed JRE's tab
.
In the project build path configuration dialog, under the libraries tab, you can delete the entry for JRE System Library
, click on Add Library
and choose the installed JRE to compile with. Some compilers can be configured to compile at a back-level compiler version. I think that's why you're seeing the addition version options.

If you're wondering how to get the file content from each ZipEntry
it's actually quite simple. Here's a sample code:
public static void main(String[] args) throws IOException {
ZipFile zipFile = new ZipFile("C:/test.zip");
Enumeration<? extends ZipEntry> entries = zipFile.entries();
while(entries.hasMoreElements()){
ZipEntry entry = entries.nextElement();
InputStream stream = zipFile.getInputStream(entry);
}
}
Once you have the InputStream you can read it however you want.
The above answers work for many cases but they miss some. Consider the following:
fl = sum([0.1]*10) # this is 0.9999999999999999, but we want to say it IS an int
Using this as a benchmark, some of the other suggestions don't get the behavior we might want:
fl.is_integer() # False
fl % 1 == 0 # False
Instead try:
def isclose(a, b, rel_tol=1e-09, abs_tol=0.0):
return abs(a-b) <= max(rel_tol * max(abs(a), abs(b)), abs_tol)
def is_integer(fl):
return isclose(fl, round(fl))
now we get:
is_integer(fl) # True
isclose
comes with Python 3.5+, and for other Python's you can use this mostly equivalent definition (as mentioned in the corresponding PEP)
<script src="//code.jquery.com/jquery.min.js"></script>

function changes() {
$('#link').val('new value');

Let's say I have Table1
with primary key _id
and a boolean column doc_availability
; Table2
with foreign key _id
and DateTime column last_update
and I want to change the availability of a document with _id
14 in Table1
to 0 i.e unavailable and update Table2
with the timestamp when the document was last updated. The following query would do the task:
UPDATE Table1, Table2
SET doc_availability = 0, last_update = NOW()
WHERE Table1._id = Table2._id AND Table1._id = 14
try the below code
execute immediate 'truncate table tablename' ;
It's more convenient to use a session, this way you don't have to remember to set headers each time:
session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})
session.get('https://httpbin.org/headers')
By default, session also manages cookies for you. In case you want to disable that, see this question.
It worked for me just by adding serverTimeZone=UTC on application.properties.

Private constructor and static methods on a class marked as final.
I liked cocogza's answer except that calling base.IsValid resulted in a stack overflow exception as it would re-enter the IsValid method again and again. So I modified it to be for a specific type of validation, in my case it was for an e-mail address.
[AttributeUsage(AttributeTargets.Property)]
class ValidEmailAddressIfTrueAttribute : ValidationAttribute
{
private readonly string _nameOfBoolProp;
public ValidEmailAddressIfTrueAttribute(string nameOfBoolProp)
{
_nameOfBoolProp = nameOfBoolProp;
}
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
if (validationContext == null)
{
return null;
}
var property = validationContext.ObjectType.GetProperty(_nameOfBoolProp);
if (property == null)
{
return new ValidationResult($"{_nameOfBoolProp} not found");
}
var boolVal = property.GetValue(validationContext.ObjectInstance, null);
if (boolVal == null || boolVal.GetType() != typeof(bool))
{
return new ValidationResult($"{_nameOfBoolProp} not boolean");
}
if ((bool)boolVal)
{
var attribute = new EmailAddressAttribute {ErrorMessage = $"{value} is not a valid e-mail address."};
return attribute.GetValidationResult(value, validationContext);
}
return null;
}
}
This works much better! It doesn't crash and produces a nice error message. Hope this helps someone!
The query either returned no rows or is erroneus, thus FALSE
is returned. Change it to
if (!$dbc || mysqli_num_rows($dbc) == 0)
mysqli_num_rows
:
Return Values
Returns TRUE on success or FALSE on failure. For SELECT, SHOW, DESCRIBE or EXPLAIN mysqli_query() will return a result object.
Add new socket connections to an array and then when you want to close all - loop through them and disconnect. (server side)
var socketlist = [];
io.sockets.on('connection', function (socket) {
socketlist.push(socket);
//...other code for connection here..
});
//close remote sockets
socketlist.forEach(function(socket) {
socket.disconnect();
});
Late to the party, but node-windows will do the trick too.
It also has system logging built in.
There is an API to create scripts from code, i.e.
var Service = require('node-windows').Service;
// Create a new service object
var svc = new Service({
name:'Hello World',
description: 'The nodejs.org example web server.',
script: 'C:\\path\\to\\helloworld.js'
});
// Listen for the "install" event, which indicates the
// process is available as a service.
svc.on('install',function(){
svc.start();
});
svc.install();

link.attr({

};
element.bind('click', function(e) {
scope.buildCSV().then(function(csv) {

Take a look at my implementation. It's safe from null lists.
IList<string> all= new List<string>();
if (letterForm.SecretaryPhone!=null)// first list may be null
all=all.Concat(letterForm.SecretaryPhone).ToList();
if (letterForm.EmployeePhone != null)// second list may be null
all= all.Concat(letterForm.EmployeePhone).ToList();
if (letterForm.DepartmentManagerName != null) // this is not list (its just string variable) so wrap it inside list then concat it
all = all.Concat(new []{letterForm.DepartmentManagerPhone}).ToList();
I've tried different cases and only when owner was set to nginx (chown -R nginx:nginx "/var/www/myfolder"
) - it started to work as expected.
You might want to try one of the following ways:
createNativeQuery(sqlString, resultClass)
Native queries can also be defined dynamically using the EntityManager.createNativeQuery()
API.
String sql = "SELECT USER.* FROM USER_ AS USER WHERE ID = ?";
Query query = em.createNativeQuery(sql, User.class);
query.setParameter(1, id);
User user = (User) query.getSingleResult();
@NamedNativeQuery
Native queries are defined through the @NamedNativeQuery
and @NamedNativeQueries
annotations, or <named-native-query>
XML element.
@NamedNativeQuery(
name="complexQuery",
query="SELECT USER.* FROM USER_ AS USER WHERE ID = ?",
resultClass=User.class
)
public class User { ... }
Query query = em.createNamedQuery("complexQuery", User.class);
query.setParameter(1, id);
User user = (User) query.getSingleResult();
You can read more in the excellent open book Java Persistence (available in PDF).

As Alex Martelli wrote, if you simply want to check if any key in B is not in A, any(True for k in dictB if k not in dictA)
would be the way to go.
To find the keys that are missing:
diff = set(dictB)-set(dictA) #sets
C:\Dokumente und Einstellungen\thc>python -m timeit -s "dictA =
dict(zip(range(1000),range
(1000))); dictB = dict(zip(range(0,2000,2),range(1000)))" "diff=set(dictB)-set(dictA)"
10000 loops, best of 3: 107 usec per loop
diff = [ k for k in dictB if k not in dictA ] #lc
C:\Dokumente und Einstellungen\thc>python -m timeit -s "dictA =
dict(zip(range(1000),range
(1000))); dictB = dict(zip(range(0,2000,2),range(1000)))" "diff=[ k for k in dictB if
k not in dictA ]"
10000 loops, best of 3: 95.9 usec per loop
So those two solutions are pretty much the same speed.
Why you don't use a DELETE CASCADE FK
?
In order to verify a client certificate is being sent to the server, you need to analyze the output from the combination of the -state
and -debug
flags.
First as a baseline, try running
$ openssl s_client -connect host:443 -state -debug
You'll get a ton of output, but the lines we are interested in look like this:
SSL_connect:SSLv3 read server done A
write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
0000 - 16 03 01 00 07 0b 00 00-03 .........
000c - <SPACES/NULS>
SSL_connect:SSLv3 write client certificate A
What's happening here:
The -state
flag is responsible for displaying the end of the previous section:
SSL_connect:SSLv3 read server done A
This is only important for helping you find your place in the output.
Then the -debug
flag is showing the raw bytes being sent in the next step:
write to 0x211efb0 [0x21ced50] (12 bytes => 12 (0xC))
0000 - 16 03 01 00 07 0b 00 00-03 .........
000c - <SPACES/NULS>
Finally, the -state
flag is once again reporting the result of the step that -debug
just echoed:
SSL_connect:SSLv3 write client certificate A
So in other words: s_client
finished reading data sent from the server, and sent 12 bytes to the server as (what I assume is) a "no client certificate" message.
If you repeat the test, but this time include the -cert
and -key
flags like this:
$ openssl s_client -connect host:443 \
-cert cert_and_key.pem \
-key cert_and_key.pem \
-state -debug
your output between the "read server done" line and the "write client certificate" line will be much longer, representing the binary form of your client certificate:
SSL_connect:SSLv3 read server done A
write to 0x7bd970 [0x86d890] (1576 bytes => 1576 (0x628))
0000 - 16 03 01 06 23 0b 00 06-1f 00 06 1c 00 06 19 31 ....#..........1
(*SNIP*)
0620 - 95 ca 5e f4 2f 6c 43 11- ..^%/lC.
SSL_connect:SSLv3 write client certificate A
The 1576 bytes
is an excellent indication on its own that the cert was transmitted, but on top of that, the right-hand column will show parts of the certificate that are human-readable: You should be able to recognize the CN and issuer strings of your cert in there.
is a concept that languages like Perl have had for quite a while, and now we’ll get this ability in C# as well. In String Interpolation, we simply prefix the string with a $ (much like we use the @ for verbatim strings). Then, we simply surround the expressions we want to interpolate with curly braces (i.e. { and }):
It looks a lot like the String.Format() placeholders, but instead of an index, it is the expression itself inside the curly braces. In fact, it shouldn’t be a surprise that it looks like String.Format() because that’s really all it is – syntactical sugar that the compiler treats like String.Format() behind the scenes.
A great part is, the compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.
C# string interpolation is a method of concatenating,formatting and manipulating strings. This feature was introduced in C# 6.0. Using string interpolation, we can use objects and expressions as a part of the string interpolation operation.
Syntax of string interpolation starts with a ‘$’ symbol and expressions are defined within a bracket {} using the following syntax.
{<interpolatedExpression>[,<alignment>][:<formatString>]}
Where:
The following code example concatenates a string where an object, author as a part of the string interpolation.
string author = "Mohit";
string hello = $"Hello {author} !";
Console.WriteLine(hello); // Hello Mohit !

From this post, try this javascript:
function removeRow(id) {
var tr = document.getElementById(id);
if (tr) {
if (tr.nodeName == 'TR') {
var tbl = tr; // Look up the hierarchy for TABLE
while (tbl != document && tbl.nodeName != 'TABLE') {
tbl = tbl.parentNode;
}
if (tbl && tbl.nodeName == 'TABLE') {
while (tr.hasChildNodes()) {
tr.removeChild( tr.lastChild );
}
tr.parentNode.removeChild( tr );
}
} else {
alert( 'Specified document element is not a TR. id=' + id );
}
} else {
alert( 'Specified document element is not found. id=' + id );
}
}
I tried this javascript in a test page and it worked for me in Firefox.
If your problem is still there it's certainly because you are trying to compile a different version from your current settings.
For example if you set your Additional Include Directories
in Debug x64, be sure that you are compiling with the same configuration.
Check this: Build > Configuration Manager... >
There is problably something like this in your active solution configuration: Debug x86 (Win32) platform
.
Use the java.lang.Math class, and specifically for absolute value and square root:, the abs()
and sqrt()
methods.
Application.Exit()
kills your application but there are some instances that it won't close the application.
End
is better than Application.Exit()

adb shell
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
This assumes your /system is yaffs2 and that it's at /dev/block/mtdblock3 the easier/better way to do this on most Android phones is:
adb shell
su
mount -o remount,rw /system
Done. This just says remount /system read-write, you don't have to specify filesystem or mount location.
For me, the only thing that worked in Java 7 on OS X 10.9 was this:
// driver = new RemoteWebDriver(new URL(grid), capability);
driver.manage().window().setPosition(new Point(0,0));
driver.manage().window().setSize(new Dimension(1024,768));
Where 1024
is the width, and 768
is the height.
Remember.. inherits is case sensitive for C# (not so for vb.net)
Found that out the hard way.
The short answer is:
int nBits = ceil(log2(N));
That's simply because pow(2, nBits) is slightly bigger than N.
There's an ELSE in the DOS batch language? Back in the days when I did more of this kinda thing, there wasn't.
If my theory is correct and your ELSE is being ignored, you may be better off doing
IF NOT EXIST file GOTO label
...which will also save you a line of code (the one right after your IF).
Second, I vaguely remember some kind of bug with testing for the existence of directories. Life would be easier if you could test for the existence of a file in that directory. If there's no file you can be sure of, something to try (this used to work up to Win95, IIRC) would be to append the device file name NUL
to your directory name, e.g.
IF NOT EXIST C:\dir\NUL GOTO ...
The Swiss Army knife of image lazy loading is YUI's ImageLoader.
Because there is more to this problem than simply watching the scroll position.
Here's a complete example of an HTTP GET request with parameters using angular.js in ASP.NET MVC:
CONTROLLER:
public class AngularController : Controller
{
public JsonResult GetFullName(string name, string surname)
{
System.Diagnostics.Debugger.Break();
return Json(new { fullName = String.Format("{0} {1}",name,surname) }, JsonRequestBehavior.AllowGet);
}
}
VIEW:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script type="text/javascript">
var myApp = angular.module("app", []);
myApp.controller('controller', function ($scope, $http) {
$scope.GetFullName = function (employee) {
//The url is as follows - ControllerName/ActionName?name=nameValue&surname=surnameValue
$http.get("/Angular/GetFullName?name=" + $scope.name + "&surname=" + $scope.surname).
success(function (data, status, headers, config) {
alert('Your full name is - ' + data.fullName);
}).
error(function (data, status, headers, config) {
alert("An error occurred during the AJAX request");
});
}
});
</script>
<div ng-app="app" ng-controller="controller">

I updated answer of Morteza Ziaeemehr to a cleaner and better code, This will unzip a file provided within form into current directory using DIR.
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8' >

}
span{
font-family: 'Consolas', 'courier new', monospace;
background: #eee;
padding:2px;
}
</style>
</head>
<body>
<div class="wrapper">
<?php
if(isset($_GET['page']))
{
$type = $_GET['page'];
global $con;
switch($type)
{
case 'unzip':
{
$zip_filename =$_POST['filename'];
echo "Unzipping <span>" .__DIR__. "/" .$zip_filename. "</span> to <span>" .__DIR__. "</span><br>";
echo "current dir: <span>" . __DIR__ . "</span><br>";
$zip = new ZipArchive;
$res = $zip->open(__DIR__ . '/' .$zip_filename);
if ($res === TRUE)
{
$zip->extractTo(__DIR__);
$zip->close();
echo '<p style="color:#00C324;">Extract was successful! Enjoy ;)</p><br>';
}
else
{
echo '<p style="color:red;">Zip file not found!</p><br>';
}
break;
}
}
}
?>
End Script.

For global setting, open the terminal (from any where) run the following:
git config --global user.name "your username"
git config --global user.password "your password"
By that, any local git repo that you have on your machine will use that information.
You can individually config for each repo by doing:
run the following:
git config user.name "your username"
git config user.password "your password"
It affects only that folder (because your configuration is local).

Commenting here as this seems to be the most popular answer on the subject for searching for files whilst excluding certain directories in powershell.
To avoid issues with post filtering of results (i.e. avoiding permission issues etc), I only needed to filter out top level directories and that is all this example is based on, so whilst this example doesn't filter child directory names, it could very easily be made recursive to support this, if you were so inclined.
Quick breakdown of how the snippet works
$folders << Uses Get-Childitem to query the file system and perform folder exclusion
$file << The pattern of the file I am looking for
foreach << Iterates the $folders variable performing a recursive search using the Get-Childitem command
$folders = Get-ChildItem -Path C:\ -Directory -Name -Exclude Folder1,"Folder 2"
$file = "*filenametosearchfor*.extension"
foreach ($folder in $folders) {
Get-Childitem -Path "C:/$folder" -Recurse -Filter $file | ForEach-Object { Write-Output $_.FullName }
}
Combining the answers above, you can implement something that works like the gem colorize without needing another dependency.
class String
# colorization
def colorize(color_code)
"\e[#{color_code}m#{self}\e[0m"
end
def red
colorize(31)
end
def green
colorize(32)
end
def yellow
colorize(33)
end
def blue
colorize(34)
end
def pink
colorize(35)
end
def light_blue
colorize(36)
end
end
I've had this same problem, and I wrote a one-liner in shell to do it.
rm -rf $(mvn help:evaluate -Dexpression=settings.localRepository\
-Dorg.slf4j.simpleLogger.defaultLogLevel=WARN -B \
-Dorg.slf4j.simpleLogger.log.org.apache.maven.cli.transfer.Slf4jMavenTransferListener=warn | grep -vF '[INFO]')/*
I did it as a one-liner because I wanted to have a Jenkins-project to simply run this whenever I needed, so I wouldn't have to log on to stuff, etc. If you allow yourself a shell-script for it, you can write it cleaner:
#!/usr/bin/env bash
REPOSITORY=$(mvn help:evaluate \
-Dexpression=settings.localRepository \
-Dorg.slf4j.simpleLogger.defaultLogLevel=WARN \
-Dorg.slf4j.simpleLogger.log.org.apache.maven.cli.transfer.Slf4jMavenTransferListener=warn \
--batch-mode \
| grep -vF '[INFO]')
rm -rf $REPOSITORY/*
Should work, but I have not tested all of that script. (I've tested the first command, but not the whole script.) This approach has the downside of running a large complicated command first. It is idempotent, so you can test it out for yourself. The deletion is its own command afterwards, and this lets you try it all out and check that it does what you think it does, because you shouldn't trust deletion commands without verification. However, it is smart for one good reason: It's portable. It respects your settings.xml file. If you're running this command, and tell maven to use a specific xml file (the -s or --settings argument), this will still work. So you don't have to fiddle with making sure everything is the same everywhere.
It's a bit wieldy, but it's a decent way of doing business, IMO.
This worked for me :
date -d '20121212 7 days'
date -d '12-DEC-2012 7 days'
date -d '2012-12-12 7 days'
date -d '2012-12-12 4:10:10PM 7 days'
date -d '2012-12-12 16:10:55 7 days'
then you can format output adding parameter '+%Y%m%d'
This is the suggested Matplotlib 3 solution from the official website HERE:
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0, 2*np.pi, 100)
y = np.sin(x)
ax = plt.subplot(111)
ax.plot(x, y)
# Hide the right and top spines
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)
# Only show ticks on the left and bottom spines
ax.yaxis.set_ticks_position('left')
ax.xaxis.set_ticks_position('bottom')
plt.show()
Noticed mine worked on chrome. Got it to work in Firefox
by going to <about:config>
and setting full-screen-api.allow-trusted-requests-only
to false
.
After full screen worked once, I could set that back to true, and full screen still worked which was quite perplexing.
The li
tag has a property called list-style-position
. This makes your bullets inside or outside the list. On default, it’s set to inside
. That makes your text wrap around it. If you set it to outside
, the text of your li
tags will be aligned.
The downside of that is that your bullets won't be aligned with the text outside the ul
. If you want to align it with the other text you can use a margin.
ul li {
/*
* We want the bullets outside of the list,
* so the text is aligned. Now the actual bullet
* is outside of the list’s container
*/
list-style-position: outside;
/*
* Because the bullet is outside of the list’s
* container, indent the list entirely
*/
margin-left: 1em;
}

elementThere's so many conflicting answers to this, most of which had no effect for me.
I was finally able to set (or retrieve current) X-axis minimum & maximum displayed values with chart.options.scales.xAxes[0].ticks.min
(even if min & max are only a subset of the data assigned to the chart.)
Using a time scale in my case, I used:
chart.options.scales.xAxes[0].ticks.min = 1590969600000; //Jun 1, 2020
chart.options.scales.xAxes[0].ticks.max = 1593561600000; //Jul 1, 2020
chart.update();
(I found no need to set the step values or beginAtZero
, etc.)

The throws Exception
declaration is an automated way of keeping track of methods that might throw an exception for anticipated but unavoidable reasons. The declaration is typically specific about the type or types of exceptions that may be thrown such as throws IOException
or throws IOException, MyException
.
We all have or will eventually write code that stops unexpectedly and reports an exception due to something we did not anticipate before running the program, like division by zero or index out of bounds. Since the errors were not expected by the method, they could not be "caught" and handled with a try catch clause. Any unsuspecting users of the method would also not know of this possibility and their programs would also stop.
When the programmer knows certain types of errors may occur but would like to handle these exceptions outside of the method, the method can "throw" one or more types of exceptions to the calling method instead of handling them. If the programmer did not declare that the method (might) throw an exception (or if Java did not have the ability to declare it), the compiler could not know and it would be up to the future user of the method to know about, catch and handle any exceptions the method might throw. Since programs can have many layers of methods written by many different programs, it becomes difficult (impossible) to keep track of which methods might throw exceptions.
Even though Java has the ability to declare exceptions, you can still write a new method with unhandled and undeclared exceptions, and Java will compile it and you can run it and hope for the best. What Java won't let you do is compile your new method if it uses a method that has been declared as throwing exception(s), unless you either handle the declared exception(s) in your method or declare your method as throwing the same exception(s) or if there are multiple exceptions, you can handle some and throw the rest.
When a programmer declares that the method throws a specific type of exception, it is just an automated way of warning other programmers using the method that an exception is possible. The programmer can then decide to handled the exception or pass on the warning by declaring the calling method as also throwing the same exception. Since the compiler has been warned the exception is possible in this new method, it can automatically check if future callers of the new method handle the exception or declare it and enforcing one or the other to happen.
The nice thing about this type of solution is that when the compiler reports Error: Unhandled exception type java.io.IOException
it gives the file and line number of the method that was declared to throw the exception. You can then choose to simply pass the buck and declare your method also "throws IOException". This can be done all the way up to main method where it would then cause the program to stop and report the exception to the user. However, it is better to catch the exception and deal with it in a nice way such as explaining to the user what has happened and how to fix it. When a method does catch and handle the exception, it no longer has to declare the exception. The buck stops there so to speak.
Yes as long as it is public and you pass the correct args. See this link for more information. http://www.codestyle.org/java/faq-CommandLine.shtml#mainhost
You can use following formulas.
For Excel 2007 or later:
=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")
For Excel 2003:
=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))
Note, that
List!A:C
in VLOOKUP
and returns value from column ? 3
VLOOKUP
equals to FALSE
, in that case VLOOKUP
will only find an exact match, and the values in the first column of List!A:C
do not need to be sorted (opposite to case when you're using TRUE
).It can be done through "Import/Export Data..." in SQL Server Management Studio
Here's how I do it using a DataTable. This is a working piece of TEST code.
using (SqlConnection con = new SqlConnection(connStr))
{
con.Open();
// Create a table with some rows.
DataTable table = MakeTable();
// Get a reference to a single row in the table.
DataRow[] rowArray = table.Select();
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(con))
{
bulkCopy.DestinationTableName = "dbo.CarlosBulkTestTable";
try
{
// Write the array of rows to the destination.
bulkCopy.WriteToServer(rowArray);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}//using
This should work for any divisor, not only three. Currently only for unsigned, but extending it to signed should not be that difficult.
#include <stdio.h>
unsigned sub(unsigned two, unsigned one);
unsigned bitdiv(unsigned top, unsigned bot);
unsigned sub(unsigned two, unsigned one)
{
unsigned bor;
bor = one;
do {
one = ~two & bor;
two ^= bor;
bor = one<<1;
} while (one);
return two;
}
unsigned bitdiv(unsigned top, unsigned bot)
{
unsigned result, shift;
if (!bot || top < bot) return 0;
for(shift=1;top >= (bot<<=1); shift++) {;}
bot >>= 1;
for (result=0; shift--; bot >>= 1 ) {
result <<=1;
if (top >= bot) {
top = sub(top,bot);
result |= 1;
}
}
return result;
}
int main(void)
{
unsigned arg,val;
for (arg=2; arg < 40; arg++) {
val = bitdiv(arg,3);
printf("Arg=%u Val=%u\n", arg, val);
}
return 0;
}
Try document.getElementById("FileUpload1").value
this value should have a path for a file to be uploaded, just strip all dirs from that value and you will have file name.
For future readers: Try this if other answers don't work (As was the case with me):
1.) Download PHPMailer, open the zip file and extract the folder to your project directory.
3.) Rename the extracted directory to PHPMailer and write the below code inside of your php script (the script must be outside of the PHPMailer folder)
<?php
// PHPMailer classes into the global namespace
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
// Base files
require 'PHPMailer/src/Exception.php';
require 'PHPMailer/src/PHPMailer.php';
require 'PHPMailer/src/SMTP.php';
// create object of PHPMailer class with boolean parameter which sets/unsets exception.
$mail = new PHPMailer(true);
try {
$mail->isSMTP(); // using SMTP protocol
$mail->Host = 'smtp.gmail.com'; // SMTP host as gmail
$mail->SMTPAuth = true; // enable smtp authentication
$mail->Username = '[email protected]'; // sender gmail host
$mail->Password = 'password'; // sender gmail host password
$mail->SMTPSecure = 'tls'; // for encrypted connection
$mail->Port = 587; // port for SMTP
$mail->setFrom('[email protected]', "Sender"); // sender's email and name
$mail->addAddress('[email protected]', "Receiver"); // receiver's email and name
$mail->Subject = 'Test subject';
$mail->Body = 'Test body';
$mail->send();
echo 'Message has been sent';
} catch (Exception $e) { // handle error.
echo 'Message could not be sent. Mailer Error: ', $mail->ErrorInfo;
}
?>
If your hardware fails then you can use mechanical storage to recover it. If your code base is small and have some physical space then you can use a mechanical data store.
There will be a surface of material which will not be affected by radiation. Multiple gears will be there. A mechanical reader will run on all the gears and will be flexible to move up and down. Down means it is 0 and up means it is 1. From 0 and 1 you can generate your code base.
A lot of people have given some very technical answers for this and similar questions, but I think it's simpler than that. Sometimes if you're not paying attention a selector that you don't intend to use can be attached to something in the interface. You might be getting this error because the selector's there but you haven't written any code for it.
The easiest way to double-check that this is not the case is to control-click the item so you can see all of the selectors that are associated with it. If there's anything in there that you don't want to be, get rid of it! Hope this helps...
And yet another way:
#include<stdio.h>
void main ()
{
int num;
printf ("=====This Program Converts ASCII to Alphabet!=====\n");
printf ("Enter ASCII: ");
scanf ("%d", &num);
printf("%d is ASCII value of '%c'", num, (char)num );
}
#include<stdio.h>
void main ()
{
char alphabet;
printf ("=====This Program Converts Alphabet to ASCII code!=====\n");
printf ("Enter Alphabet: ");
scanf ("%c", &alphabet);
printf("ASCII value of '%c' is %d", alphabet, (char)alphabet );
}
Here goes a straightforward example:
# Do something, or tell me why it failed
my_update_function <- function(x){
tryCatch(
# This is what I want to do...
{
y = x * 2
return(y)
},
# ... but if an error occurs, tell me what happened:
error=function(error_message) {
message("This is my custom message.")
message("And below is the error message from R:")
message(error_message)
return(NA)
}
)
}
If you also want to capture a "warning", just add warning=
similar to the error=
part.
You'll do it the same way you would apply a css selector. For instanse you can do
$("#mydiv > .myclass")
or
$("#mydiv .myclass")
The last one will match every myclass inside myDiv, including myclass inside myclass.
Use history.replaceState
or history.pushState
* to change the hash. This will not trigger the jump to the associated element.
$(document).on('click', 'a[href^=#]', function(event) {
event.preventDefault();
history.pushState({}, '', this.href);
});
* If you want history forward and backward support
If you are using history.pushState
and you don't want page scrolling when the user uses the history buttons of the browser (forward/backward) check out the experimental scrollRestoration
setting (Chrome 46+ only).
history.scrollRestoration = 'manual';
I created an extension for RelativeLayout
that shows/hides Layouts with animations.
It can extend any kind of View
to gain these features.
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationSet;
import android.view.animation.AnimationUtils;
import android.widget.RelativeLayout;
public class AnimatingRelativeLayout extends RelativeLayout
{
Context context;
Animation inAnimation;
Animation outAnimation;
public AnimatingRelativeLayout(Context context)
{
super(context);
this.context = context;
initAnimations();
}
public AnimatingRelativeLayout(Context context, AttributeSet attrs)
{
super(context, attrs);
this.context = context;
initAnimations();
}
public AnimatingRelativeLayout(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
this.context = context;
initAnimations();
}
private void initAnimations()
{
inAnimation = (AnimationSet) AnimationUtils.loadAnimation(context, R.anim.in_animation);
outAnimation = (Animation) AnimationUtils.loadAnimation(context, R.anim.out_animation);
}
public void show()
{
if (isVisible()) return;
show(true);
}
public void show(boolean withAnimation)
{
if (withAnimation) this.startAnimation(inAnimation);
this.setVisibility(View.VISIBLE);
}
public void hide()
{
if (!isVisible()) return;
hide(true);
}
public void hide(boolean withAnimation)
{
if (withAnimation) this.startAnimation(outAnimation);
this.setVisibility(View.GONE);
}
public boolean isVisible()
{
return (this.getVisibility() == View.VISIBLE);
}
public void overrideDefaultInAnimation(Animation inAnimation)
{
this.inAnimation = inAnimation;
}
public void overrideDefaultOutAnimation(Animation outAnimation)
{
this.outAnimation = outAnimation;
}
}
You can override the original Animation
s using overrideDefaultInAnimation
and overrideDefaultOutAnimation
My original Animations were fadeIn/Out, I am adding XML animation files for Translating in/out of the screen (Translate to top and from top)
in_animation.xml:
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="600"
android:fillAfter="false"
android:fromXDelta="0"
android:fromYDelta="-100%p"
android:toXDelta="0"
android:toYDelta="0" />
out_animation.xml:
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="600"
android:fillAfter="false"
android:fromXDelta="0"
android:fromYDelta="0"
android:toXDelta="0"
android:toYDelta="-100%p" />
Put parentheses around the "OR"s:
SELECT ads.*, location.county
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1
AND ads.type = 13
AND
(
ads.county_id = 2
OR ads.county_id = 5
OR ads.county_id = 7
OR ads.county_id = 9
)
Or even better, use IN:
SELECT ads.*, location.county
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1
AND ads.type = 13
AND ads.county_id IN (2, 5, 7, 9)
foreach (DataGridViewRow row in dataGridView1.Rows)
{
for (int i = 0; i < dataGridView1.Columns.Count; i++)
{
String header = dataGridView1.Columns[i].HeaderText;
//String cellText = row.Cells[i].Text;
DataGridViewColumn column = dataGridView1.Columns[i]; // column[1] selects the required column
column.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells; // sets the AutoSizeMode of column defined in previous line
int colWidth = column.Width; // store columns width after auto resize
colWidth += 50; // add 30 pixels to what 'colWidth' already is
this.dataGridView1.Columns[i].Width = colWidth; // set the columns width to the value stored in 'colWidth'
}
}
Maybe you can use WebView, but as you can see in the doc WebView doesn't support javascript and other stuff like widgets by default.
http://developer.android.com/reference/android/webkit/WebView.html
I think that you can enable javascript if you need it.
NSString* NSStringWithoutSpace(NSString* string)
{
return [string stringByReplacingOccurrencesOfString:@" " withString:@""];
}
If you create your own adapter, there is one notable abstract function:
public void registerDataSetObserver(DataSetObserver observer) {
...
}
You can use the given observers to notify the system to update:
private ArrayList<DataSetObserver> observers = new ArrayList<DataSetObserver>();
public void registerDataSetObserver(DataSetObserver observer) {
observers.add(observer);
}
public void notifyDataSetChanged(){
for (DataSetObserver observer: observers) {
observer.onChanged();
}
}
Though aren't you glad there are things like the SimpleAdapter and ArrayAdapter and you don't have to do all that?
For the first solution proposed by Joe Kington ( .copy_from_bbox & .draw_artist & canvas.blit), I had to capture the backgrounds after the fig.canvas.draw() line, otherwise the background had no effect and I got the same result as you mentioned. If you put it after the fig.show() it still does not work as proposed by Michael Browne.
So just put the background line after the canvas.draw():
[...]
fig.show()
# We need to draw the canvas before we start animating...
fig.canvas.draw()
# Let's capture the background of the figure
backgrounds = [fig.canvas.copy_from_bbox(ax.bbox) for ax in axes]
Ctrl + MouseWheel works on almost anything...not just visual studio
You can use Array.push()
for appending elements to an array.
For deleting, it is best to use this.$delete(array, index)
for reactive objects.
Vue.delete( target, key )
: Delete a property on an object. If the object is reactive, ensure the deletion triggers view updates. This is primarily used to get around the limitation that Vue cannot detect property deletions, but you should rarely need to use it.
In urlip3 there's no .urlopen
, instead try this:
import requests
html = requests.get(url)
Use __dirname!!
__dirname
The directory name of the current module. This the same as the path.dirname() of the __filename
.
Example: running node example.js from /Users/mjr
console.log(__dirname);
// Prints: /Users/mjr
console.log(path.dirname(__filename));
// Prints: /Users/mjr
https://nodejs.org/api/modules.html#modules_dirname
For ESModules you would want to use:
import.meta.url
The ideal way would be to add CORS support to your server.
You could also try using a separate jsonp module. As far as I know axios does not support jsonp. So I am not sure if the method you are using would qualify as a valid jsonp request.
There is another hackish work around for the CORS problem. You will have to deploy your code with an nginx server serving as a proxy for both your server and your client.
The thing that will do the trick us the proxy_pass
directive. Configure your nginx server in such a way that the location block handling your particular request will proxy_pass
or redirect your request to your actual server.
CORS problems usually occur because of change in the website domain.
When you have a singly proxy serving as the face of you client and you server, the browser is fooled into thinking that the server and client reside in the same domain. Ergo no CORS.
Consider this example.
Your server is my-server.com
and your client is my-client.com
Configure nginx as follows:
// nginx.conf
upstream server {
server my-server.com;
}
upstream client {
server my-client.com;
}
server {
listen 80;
server_name my-website.com;
access_log /path/to/access/log/access.log;
error_log /path/to/error/log/error.log;
location / {
proxy_pass http://client;
}
location ~ /server/(?<section>.*) {
rewrite ^/server/(.*)$ /$1 break;
proxy_pass http://server;
}
}
Here my-website.com
will be the resultant name of the website where the code will be accessible (name of the proxy website).
Once nginx is configured this way. You will need to modify the requests such that:
my-server.com/<API-path>

In case you are not familiar with nginx I would advise you to go through the documentation.
To explain what is happening in the configuration above in brief:
upstream
s define the actual servers to whom the requests will be redirectedserver
block is used to define the actual behaviour of the nginx server.server_name
is used to identify the block which will be used to handle the current request. error_log
and access_log
directives are used to define the locations of the log files (used for debugging)location
blocks define the handling of different types of requests:
/
all these requests are redirected to the client/server/<API-path>
. We will be redirecting all such requests to the server.Note: /server
here is being used to distinguish the client side requests from the server side requests. Since the domain is the same there is no other way of distinguishing requests. Keep in mind there is no such convention that compels you to add /server
in all such use cases. It can be changed to any other string eg. /my-server/<API-path>
, /abc/<API-path>
, etc.
Even though this technique should do the trick, I would highly advise you to add CORS support to the server as this is the ideal way situations like these should be handled.
If you wish to avoid doing all this while developing you could for this chrome extension. It should allow you to perform cross domain requests during development.
You don't directly read a value. You can set it with .setValue()
, but there is no .getValue() on the reference object.
You have to use a listener. If you just want to read the value once, you use ref.addListenerForSingleValueEvent()
.
Example:
Firebase ref = new Firebase("YOUR-URL-HERE/PATH/TO/YOUR/STUFF");
ref.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
String value = (String) dataSnapshot.getValue();
// do your stuff here with value
}
@Override
public void onCancelled(FirebaseError firebaseError) {
}
});

change the your servlet name dispatcher to any other name .because dispatcher is predefined name for spring3,spring4 versions.
<servlet>
<servlet-name>ahok</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ashok</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
This is my proposed solution:
void showProgressDialog()
method can be added to the fragment-activity listener interface for this purpose.If the image is too large and you can't save&load it to the storage, you should consider just using a global static reference to the bitmap (inside the receiving activity), which will be reset to null on onDestory, only if "isChangingConfigurations" returns true.
NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];
or use
NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);
Barring the CSS solution. The fastest possible way is to hide it immediatly with a script.
<div id="hideme"></div>
<script type="text/javascript">
$("#hideme").hide();
</script>
In this case I would recommend the CSS solution by Vega. But if you need something more complex (like an animation) you can use this approach.
This has some complications (see comments below). If you want this piece of script to really run as fast as possible you can't use jQuery, use native JS only and defer loading of all other scripts.
This is currently not possible with CSS alone as @BoltClock wrote in the accepted answer, but you can work around that by using JavaScript.
I created a container query (aka element query) prolyfill to solve this kind of issue. It works a bit different than other scripts, so you don’t have to edit the HTML code of your elements. All you have to do is include the script and use it in your CSS like so:
.element:container(width > 99px) {
/* If its container is at least 100px wide */
}
There is indeed a big difference, which you should keep in mind. setScale really set the scale of your number whereas round does round your number to the specified digits BUT it "starts from the leftmost digit of exact result" as mentioned within the jdk. So regarding your sample the results are the same, but try 0.0034 instead. Here's my note about that on my blog:
http://araklefeistel.blogspot.com/2011/06/javamathbigdecimal-difference-between.html
Another solution could be following:
This is how you use it:
final Opt<String> opt = Opt.of("I'm a cool text");
opt.ifPresent()
.apply(s -> System.out.printf("Text is: %s\n", s))
.elseApply(() -> System.out.println("no text available"));
Or in case you in case of the opposite use case is true:
final Opt<String> opt = Opt.of("This is the text");
opt.ifNotPresent()
.apply(() -> System.out.println("Not present"))
.elseApply(t -> /*do something here*/);
This are the ingredients:
The "cosmetically" enhanced Function interface.
@FunctionalInterface
public interface Fkt<T, R> extends Function<T, R> {
default R elseApply(final T t) {
return this.apply(t);
}
}
And the Optional wrapper class for enhancement:
public class Opt<T> {
private final Optional<T> optional;
private Opt(final Optional<T> theOptional) {
this.optional = theOptional;
}
public static <T> Opt<T> of(final T value) {
return new Opt<>(Optional.of(value));
}
public static <T> Opt<T> of(final Optional<T> optional) {
return new Opt<>(optional);
}
public static <T> Opt<T> ofNullable(final T value) {
return new Opt<>(Optional.ofNullable(value));
}
public static <T> Opt<T> empty() {
return new Opt<>(Optional.empty());
}
private final BiFunction<Consumer<T>, Runnable, Void> ifPresent = (present, notPresent) -> {
if (this.optional.isPresent()) {
present.accept(this.optional.get());
} else {
notPresent.run();
}
return null;
};
private final BiFunction<Runnable, Consumer<T>, Void> ifNotPresent = (notPresent, present) -> {
if (!this.optional.isPresent()) {
notPresent.run();
} else {
present.accept(this.optional.get());
}
return null;
};
public Fkt<Consumer<T>, Fkt<Runnable, Void>> ifPresent() {
return Opt.curry(this.ifPresent);
}
public Fkt<Runnable, Fkt<Consumer<T>, Void>> ifNotPresent() {
return Opt.curry(this.ifNotPresent);
}
private static <X, Y, Z> Fkt<X, Fkt<Y, Z>> curry(final BiFunction<X, Y, Z> function) {
return (final X x) -> (final Y y) -> function.apply(x, y);
}
}
This should do the trick and could serve as a basic template how to deal with such requirements.
The basic idea here is following. In a non functional style programming world you would probably implement a method taking two parameter where the first is a kind of runnable code which should be executed in case the value is available and the other parameter is the runnable code which should be run in case the value is not available. For the sake of better readability, you can use curring to split the function of two parameter in two functions of one parameter each. This is what I basically did here.
Hint: Opt also provides the other use case where you want to execute a piece of code just in case the value is not available. This could be done also via Optional.filter.stuff but I found this much more readable.
Hope that helps!
Good programming :-)
Below code(jQuery.isEmptyObject(anyObject) function is already provided) works perfectly fine, no need to write one of your own.
// works for any Object Including JSON(key value pair) or Array.
// var arr = [];
// var jsonObj = {};
if (jQuery.isEmptyObject(anyObjectIncludingJSON))
{
console.log("Empty Object");
}
if you just want any letters:
'a'*10 # gives 'aaaaaaaaaa'
if you want consecutive letters (up to 26):
''.join(['%c' % x for x in range(97, 97+10)]) # gives 'abcdefghij'
What does res.render do and what does the html file look like?
res.render()
function compiles your template (please don't use ejs), inserts locals there, and creates html output out of those two things.
Answering Edit 2 part.
// here you set that all templates are located in `/views` directory
app.set('views', __dirname + '/views');
// here you set that you're using `ejs` template engine, and the
// default extension is `ejs`
app.set('view engine', 'ejs');
// here you render `orders` template
response.render("orders", {orders: orders_json});
So, the template path is views/
(first part) + orders
(second part) + .ejs
(third part) === views/orders.ejs
Anyway, express.js documentation is good for what it does. It is API reference, not a "how to use node.js" book.
Write it as below
<script language="javascript">
var visitorName = 'Chuck';
var myOldString = 'Hello username. I hope you enjoy your stay username.';
var myNewString = myOldString.replace('username', visitorName);
document.write('Old String = ' + myOldString);
document.write('<br/>New string = ' + myNewString);
</script>
simply just use click event my check box id is CheckAll
$('#CheckAll').click(function () {
if ($('#CheckAll').is(':checked') == true) {
alert(";)");
}
}
setTimeout
may help out here
$("#message_link").click(function(){
setTimeout(function() {
if (some_conditions...){
$("#header").append("<div><img alt=\"Loader\"src=\"/images/ajax-loader.gif\" /></div>");
}
}, 100);
});
That will cause the div to be appended ~100ms after the click event occurs, if some_conditions are met.
There are three ways to do what you want
This includes something like php, asp, jsp.... But you said no to that
Your server is serving up the pages so why not take advantage of the built in server side includes? Each server has its own way to do this, take advantage of it.
This solutions has you calling back to the server after page has already been loaded on the client.
you can also use PHP short tag to make it shorter. here's an example
<a href="<?= site_url('controller/function'); ?>Contacts</a>
or use the built in anchor function of CI.
For anyone using Python 3.8 or newer I recommend using "Assignment Expressions" as described in PEP 572 -- Assignment Expressions.
if any((match := i) > 3 for i in range(10)):
print(match)
Try the following:
<script>
//Functions to open database and to create, insert data into tables
getSelectedRow = function(val)
{
db.transaction(function(transaction) {
transaction.executeSql('SELECT * FROM Employ where number = ?;',[parseInt(val)], selectedRowValues, errorHandler);
});
};
selectedRowValues = function(transaction,results)
{
for(var i = 0; i < results.rows.length; i++)
{
var row = results.rows.item(i);
alert(row['number']);
alert(row['name']);
}
};
</script>
You don't have access to javascript variable names in SQL, you must pass the values to the Database.
for windows try left Ctrl key with F11 or F12 or Num off 7
SUM CASE using example:
SELECT
DISTINCT(p.`ProductID`) AS ProductID,
SUM(IF(p.`PaymentMethod`='Cash',Amount,0)) AS Cash_,
SUM(IF(p.`PaymentMethod`='Check',Amount,0)) AS Check_,
SUM(IF(p.`PaymentMethod`='Credit Card',Amount,0)) AS Credit_Card_,
SUM( CASE PaymentMethod
WHEN 'Cash' THEN Amount
WHEN 'Check' THEN Amount
WHEN 'Credit Card' THEN Amount
END) AS Total
FROM
`payments` AS p
GROUP BY p.`ProductID`;

To tell from the style of your code snippet, I suppose you were using IPython rather than Jupyter Notebook.
In this issue on GitHub, it was made clear by a member of IPython in 2016 that the display of charts would only work when "only work when it's a Jupyter kernel". Thus, the %matplotlib inline
would not work.
I was just having the same issue and suggest you use Jupyter Notebook for the visualization.
:g/^$/d
:g
will execute a command on lines which match a regex. The regex is 'blank line' and the command is :d
(delete)
None of these solutions quite worked for me. My original audio was being overwritten, or I was getting an error like "failed to map memory" with the more complex 'amerge' example. It seems I needed -filter_complex amix.
ffmpeg -i videowithaudioyouwanttokeep.mp4 -i audiotooverlay.mp3 -vcodec copy -filter_complex amix -map 0:v -map 0:a -map 1:a -shortest -b:a 144k out.mkv
From the manual: The SELECT ... INTO OUTFILE
statement is intended primarily to let you very quickly dump a table to a text file on the server machine. If you want to create the resulting file on some client host other than the server host, you cannot use SELECT ... INTO OUTFILE
. In that case, you should instead use a command such as mysql -e "SELECT ..." > file_name
to generate the file on the client host."
http://dev.mysql.com/doc/refman/5.0/en/select.html
An example:
mysql -h my.db.com -u usrname--password=pass db_name -e 'SELECT foo FROM bar' > /tmp/myfile.txt
With array_intersect_key
and array_flip
:
var_dump(array_intersect_key($my_array, array_flip($allowed)));
array(1) {
["foo"]=>
int(1)
}
If you want an ImageView
that both scales up and down while keeping the proper aspect ratio, add this to your XML:
android:adjustViewBounds="true"
android:scaleType="fitCenter"
Add this to your code:
// We need to adjust the height if the width of the bitmap is
// smaller than the view width, otherwise the image will be boxed.
final double viewWidthToBitmapWidthRatio = (double)image.getWidth() / (double)bitmap.getWidth();
image.getLayoutParams().height = (int) (bitmap.getHeight() * viewWidthToBitmapWidthRatio);
It took me a while to get this working, but this appears to work in the cases both where the image is smaller than the screen width and larger than the screen width, and it does not box the image.
The same way -- e.g. if you have an 8-bit char, 7 bits can be used for magnitude and 1 for sign. So an unsigned char might range from 0 to 255, whilst a signed char might range from -128 to 127 (for example).
Online index rebuilds are less intrusive when it comes to locking tables. Offline rebuilds cause heavy locking of tables which can cause significant blocking issues for things that are trying to access the database while the rebuild takes place.
"Table locks are applied for the duration of the index operation [during an offline rebuild]. An offline index operation that creates, rebuilds, or drops a clustered, spatial, or XML index, or rebuilds or drops a nonclustered index, acquires a Schema modification (Sch-M) lock on the table. This prevents all user access to the underlying table for the duration of the operation. An offline index operation that creates a nonclustered index acquires a Shared (S) lock on the table. This prevents updates to the underlying table but allows read operations, such as SELECT statements."
http://msdn.microsoft.com/en-us/library/ms188388(v=sql.110).aspx
Additionally online index rebuilds are a enterprise (or developer) version only feature.
If you are using Eclipse,
They should all be in there. Right click and "checkout."
That error usually occurs when you try to subtract an interval from DateTime.MinValue
or you want to add something to DateTime.MaxValue
(or you try to instantiate a date outside this min-max interval). Are you sure you're not assigning MinValue
somewhere?
It is, but requires a CSS2 capable browser (all major browsers, IE8+).
.OwnerJoe:before {
content: "Joe's Task:";
}
But I would rather recommend using Javascript for this. With jQuery:
$('.OwnerJoe').each(function() {
$(this).before($('<span>').text("Joe's Task: "));
});
This is array initializer syntax, and it can only be used on the right-hand-side when declaring a variable of array type. Example:
int[] x = {1,2,3,4};
String y = {"a","b","c"};
If you're not on the RHS of a variable declaration, use an array constructor instead:
int[] x;
x = new int[]{1,2,3,4};
String y;
y = new String[]{"a","b","c"};
These declarations have the exact same effect: a new array is allocated and constructed with the specified contents.
In your case, it might actually be clearer (less repetitive, but a bit less concise) to specify the table programmatically:
double[][] m = new double[4][4];
for(int i=0; i<4; i++) {
for(int j=0; j<4; j++) {
m[i][j] = i*j;
}
}
