Example: no target device found android studio Choose "Run" then "Edit Configurations". In the "General" tab, check the "Deployment Target Options" section. In my case, the target was already set to "USB Device" and the checkbox "Use same device for future launches" was checked. I had to change the target to "Show Device Chooser Dialog" and I unchecked the check box. Then my device appeared in the list. If your device still doesn't appear, then you have to enable USB-Debugging in the smartphone settings again.

Answer : Put this as the first line in C:\...\httpd-vhosts.conf (and restart the web server): NameVirtualHost *:80 So, it should look like this: NameVirtualHost *:80 <VirtualHost *:80> ServerName localhost DocumentRoot "C:/xampp/htdocs" </VirtualHost> <VirtualHost *:80> ServerName walkpeakdistrict.local DocumentRoot "C:/xampp/htdocs/walkpeakdistrict_uk/public" </VirtualHost> I would place all my projects somewhere outside of C:/xampp/htdocs and C:/xampp . Let C:/xampp/htdocs be the standard localhost location, with just two files inside (simple index.php and index.html ), but use another one for the projects. Even better, use another partition, not the system partition C: . Like D:/projects , or so. So, you would have D:/projects/walkpeakdistrict_uk . Good luck. Ok, I'm not sure why this was an issue but it seems to work when I change the virtual host's server name to anything other than ".loca

Example 1: javascript check if number //Updated dec 2020 // The first 2 Variations return a Boolean // They just work the opposite way around // IsInteger if (Number.isInteger(val)) { // It is indeed a number } // isNaN (is not a number) if (isNaN(val)) { // It is not a number } // Another option is typeof which return a string if (typeof(val) === 'number') { // Guess what, it's a bloody number! } Example 2: javascript check if number function isNumber(n) { return /^-?[\d.]+(?:e-?\d+)?$/.test(n); } ------------------------ isNumber('123'); // true isNumber('123abc'); // false isNumber(5); // true isNumber('q345'); // false isNumber(null); // false isNumber(undefined); // false isNumber(false); // false isNumber(' '); // false Example 3: To check if a value is a number in JavaScript const value = 2 isNaN(value) //false isNaN('test') //true isNaN({}) //true isNaN(1.2) //false

Answer : Always working workaround (Manual download) Download directly from Apple: Latest Release version or Latest Beta version or Any version you need. And all other downloadable contents Then extract and move it where you like. This has so many benefits comparing to appstore update. (like the ability to resume download, not replacing the old one, not wasting hidden directories and etc.) Note that you should use safari to download it. Apple suggested workaround (Force App Store to redownload) Since This is Known Issues Xcode may fail to update from the Mac App Store after updating to macOS Catalina. (56061273) Apple suggest this: To trigger a new download you can delete the existing Xcode.app or temporarily change the file extension so it is no longer visible to the App Store.

Answer : The ZIP format doesn't allow for encrypting file lists. This means that file lists are viewable by anyone. Only the contents of the files is encrypted, which means that no one can read the file without your password. Due to this, 7-Zip only asks for your password before unzipping. If you need a format that encrypts the file list, use 7Z and make sure you check "Encrypt File Names". For the more technical minded, the ZIP specification doesn't allow for encryption of the Central Directory. You will be prompted for a password when you try to extract the files. To simply view the contents of the archive does not require a password. If you would like to obfuscate the contents of the archive, compress the directory into an archive, and then compress that archive with a password. Thus, you will have to extract the archive with a password, to pull out the archived (and obfuscated) contents. A generalized solution that works for all zip programs (WI

Answer : But shouldn't it suppose verify before I get the OTP? What's the reason, Isn' it a security issue? This is absolutely NOT a security issue! quite the opposite it's a protection. Lets go through the steps. You put in card details. You put in CVV You put in the OTP. The payment is processed if and only if the combination of all of it are correct. Now assume a scenario where it tell's you the CVV is wrong before the 2FA that is just going to simply give the attacker a chance to better attack.Now the attacker knows the CVV is wrong and can simply change that.While in the correct scenario attacker will have to break 2 Factor authentication to gain that information As well as the general rule of not giving the attacker information by rejecting too early, there are some things specific to the payment industry which are somewhat relevant. Although often presented to the customer as mandatory, the authentication information on a payment i

Example 1: Write a Program to find exponential without using pow() method # include <stdio.h> int main ( ) { int base , exp ; long long result = 1 ; printf ( "Enter a base number: " ) ; scanf ( "%d" , & base ) ; printf ( "Enter an exponent: " ) ; scanf ( "%d" , & exp ) ; while ( exp != 0 ) { result *= base ; -- exp ; } printf ( "Answer = %lld" , result ) ; return 0 ; } Example 2: power func in c The function pow ( ) is used to calculate the power raised to the base value . It takes two arguments . It returns the power raised to the base value . It is declared in “math . h” header file . Example 3: powers of 2 in cpp // If not using any extra libraries // Powers of 2.
