[ad_1] Q1. can we compile this java class? Note we don’t have a main method in this class. Yes, that class should compile.

[ad_1] In SQL Server, the update should start: update TBLSurvey set Status = -1 from TBLSurvey . . . The syntax for update in SQL Server is here. If I had to guess, it looks like you are confused with aspects of MySQL syntax. [ad_2] solved Incorrect syntax near the keyword ‘set’ and ‘as’ [closed]
[ad_1] Just change scanf(“%c”,&one); to scanf(” %c”,&one); and scanf(“%c”,&two); to scanf(” %c”,&two); scanf function seems to be skipped in c 1 [ad_2] solved C Programming Rock-Paper-Scissors Not Working [duplicate]
[ad_1] .your-div-class:hover, .your-div-class:focus { color: #fff; } side note: check in your code that .your-div-class or any class associated to its inner text hasn’t a color assigned with !important, in that case either remove the !important or assign it to the hover too. EDIT: try this: .schedule-layout2 .schedule-nav li:hover .day-number { color: #fff !important; } … Read more
[ad_1] If you really want to implement this as a macro then you need to remove the return from inside the macro. You can’t assign the “result” of your macro to a variable as it is not a single statement. #include <cstdio> #define IPV4_ZEROVAL_CHECK(ip, result) {int d1,d2,d3,d4; result = (4 == sscanf(ip, “%d.%d.%d.%d”, &d1, &d2, … Read more
[ad_1] Here is the simplest version using your original line of thoughts Implementing a range function can be more complex than this, but since this works, I suggest it for now function buildArray(a, b) { var arr = []; for (var i = a; i <= b; i++) { arr.push(i); } return arr; } console.log(buildArray(5, … Read more
[ad_1] You don’t have to make the member names match the SQL column names. If you’re using some kind of ORM, there’s almost always a way to specify the mapping explicitly. For ADO.Net, obviously you’re free to use the names as appropriate. I’d rename the member NoteText. I’d also consider applying the same change in … Read more
[ad_1] The problem is the condition becomes false in the first instance of the loop , 5/360 would be 0.013888 which is less than 0.0 , So it would not enter to append the text which you are trying to do. So the loop exists and the object text has only the initial value which … Read more
[ad_1] You can do aggregation with coalesce() : select event_id, coalesce(max(case when state=”FAILED” then ‘FAILED’ end), max(case when state=”COMPLETED” then ‘COMPLETED’ end), ‘PENDING’ ) from table t group by event_id; [ad_2] solved Very complicated SQL query
[ad_1] Nullable types can hold nulls. When type is nullable the question mark is set after it’s type: val str: String? = null Non-nullable types can’t hold nulls: val str: String = “some value” If we try to set null value to Non-nullable type, IDE will give an error and code will not be compiled: … Read more

[ad_1] Just set onClick in the XML, it’s much easier. android:onClick=”whatever” Then in your class, public void whatever(View v) { // Do your stuff } You do not need all this: button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { image.setImageResource(R.drawable.player_pause); } }); 1 [ad_2] solved button.setOnClickListener not working
[ad_1] You are setting the query before you add the filter to the query string. // Get the results from the query $query->setQuery($sqlSelect) ->setParameter(‘startMonth’, $startMonth) ->setParameter(‘endMonth’, $endMonth); if (!empty($filter)) { $sqlSelect .= ‘AND LOG.VALUE LIKE :filter ‘; $query->setParameter(‘filter’, ‘%’.$filter.’%’); } You are setting the query to $sqlSelect and aftwards appending the filter part after setting … Read more
[ad_1] for ( a = line.getSize() – 1; a >= 0; a–); test(a, line); } You have a semicolon at the end of your for loop. What happens is that the for loop loops but never executes test. So a is set to -1 through the iterations then test is called. Get rid of the … Read more
[ad_1] You should be able to just use string concatenation with +. mfile.open ( accname + “.txt”); If you are not on c++ 11, then you probably need a C-style string. mfile.open ( (accname + “.txt”).c_str()); 5 [ad_2] solved C++ Probllem with output [closed]
