Use this it works….. create boolean variable as global within class but outside methods. boolean flag=true; and add this clicked method. @Override public void onClick(View v) { if (flag){ power.setVisibility(View.GONE); flag=false; } else { flag=true; power.setVisibility(View.VISIBLE);} } }); mute always visible , because you performing visibility with power that why the result coming same. enjoy … Read more
NSMutableString.string is a hack. It “works” for the same reason that myString.length and [myString length] produce the same result. However, since dot notation is not used with an actual property, it is an abuse of the language feature, because properties have a different semantic. For example, when you access a property multiple times, you naturally … Read more
Starting at the left hand side: struct foo *ptr declares ptr to be of type struct foo *, that is a pointer to struct foo. The = initializes that ptr variable to whatever the right hand side evaluates as. And the right hand side (struct foo *) p2 is an expression that casts p2 to … Read more
Maybe something like this: SELECT b.id FROM iv_stock_details a, iv_stock_details b WHERE a.id + 1 = b.id AND b.stock_stat_no >= a.stock_stat_no AND b.stock_stat_no < a.stock_end_no AND b.stock_end_no <= a.stock_end_no AND b.stock_end_no > a.stock_stat_no; SQLFiddle: http://sqlfiddle.com/#!2/94722/7 solved Compare nth row with n+1 th row and if it lies in range of n th row print n+1th … Read more
The if and the else both have different scopes. Variables declared in the if can be used only in the if and any of its children Similarly, variables declared in the else can be used only in the else and any of its children Read more about variable scope for more information. solved Why does … Read more
You need to handle the exception for Runtime.getRuntime().exec(“calc”);. Try this: else if(e.getActionCommand().equals(“Window Calculator”)){ try { Runtime.getRuntime().exec(“calc”); } catch(IOException ioe) { ioe.printStackTrace(); } } From OP comments: If i catch the exception,how will it help..the code that i want to use will not be executed by this This will not help you to run your code … Read more
Yes it is largely possible (though there are some caveats and counter examples discussed in the answers here) SELECT * FROM Foo WHERE 1 = CASE WHEN Name IN ( ‘name1’, ‘name2’ ) THEN CASE WHEN Type = 1 THEN CASE WHEN ( Date < ‘2013-01-01’ AND Date > ‘2010-01-01’ ) THEN 1 END END … Read more
Perhaps what you’re looking for is an Array or List. Both of these can contain a sequence of multiple values, which would allow you to do this, for example: var resultArray = new[] { sqlCmd2.ExecuteScalar().ToString(), sqlCmd3.ExecuteScalar().ToString() }; // Read results with resultArray[0], resultArray[1] Another option is to assign each result to an object property: var … Read more
In your second code block you are first checking if the first character is the same as the last. If it isn’t, return false. Else, return true. So this isn’t going to be a valid palindrome check. It only checks if the first and last letters are the same or not and ignores the letters … Read more
This sub procedure works with two variant arrays.

you can use id to get the element you want to style. <!DOCTYPE html> <html> <body> <p id=”myp”>Click the button to change the style of the p element.</p> <button onclick=”myFunction()”>Try it</button> <script> function myFunction() { var color1 = Math.floor((Math.random() * 255) + 1); var color2 = Math.floor((Math.random() * 255) + 1); var color3 = Math.floor((Math.random() … Read more
You could use reduce for this kind of thing, here is an example: var calendar = {Q1 : {P1 : {WK1 : {start: ‘1/1/2018’,end: ‘1/7/2018’},WK2 : {start: ‘1/8/2018’,end: ‘1/14/2018’}},P2 : {WK3 : {start: ‘1/15/2018’,end: ‘1/21/2018’}}},Q2 : {P3 : {WK5 : {start: ‘2/1/2018’,end: ‘2/7/2018’},WK6 : {start: ‘2/8/2018’,end: ‘2/14/2018’}},P4 : {WK7 : {start: ‘2/15/2018’,end: ‘2/21/2018’}}}}; var result … Read more
If the encryption method is an accepted standard method such as AES and the key is good it is not possible to find the key given the plain and encrypted data. If the encryption method is trivial such as Caeser Cipher then it can be found. If the key is trivial such as “password” or … Read more
Unboxing When you call a method that wants a boolean but give it a Boolean, Java has to unbox the value. This happens automatically and implicitly. Therefore, during compilation, Java replaces your call foo(value); by foo(value.booleanValue()); This process is explained in detail in JLS, chapter 5.1.8. Unboxing Conversion: At run time, unboxing conversion proceeds as … Read more
These are different symbols. Add these lines to your fiddle to see it: Console.WriteLine((int)’‐’); Console.WriteLine((int)’-‘); You can write your own comparison function and treat all different variants of hyphen as the same symbol or you can replace all such symbols in your strings with the one hyphen variant before the comparison. 3 solved Why is … Read more
