[ad_1] It’s just 106 “public final static int int1 = int1value” in the first class. No List or Arrays. How lame! Unfortunately there is no neat way to sum the values of a large number of statics. You could do it using reflection (see @BalusC’s answer), or simply by writing a method evaluates hard-wired expressions … Read more
[ad_1] I don’t think you need 3 queries. One should be fine selecting both values. Queries 2 & 3 are identical anyway. $result1 = mysqli_query($con,”SELECT company_id, closed_state FROM tbl_company WHERE company_id=’$company_id'”) or die(mysql_error()); while($row = mysqli_fetch_array($result1)){ if ($row[‘closed_state’] == “yes”){ echo ‘<a href=”https://stackoverflow.com/questions/30514499/customers_open.php?company_id=”.$row[‘company_id’].'”>Reopen account</a>’; }else{ echo ‘<a href=”customers_close.php?company_id=’.$row[‘company_id’].'”>Close account</a>’; } } 1 [ad_2] solved Best … Read more

[ad_1] You cannot do it for local variables like this. For member fields you can use reflection; for locals, the simplest approach is to use Dictionary, for example, like this: IDictionary<string,string> vars = new Dictionary<string,string> { {“one”, “find”} , {“two”, “cancel”} }; combobox1.text = vars[“one”]; [ad_2] solved Use of string as an existing variable in … Read more
[ad_1] Moving the line stringstream aa; just before the line aa << b; solves the problem for me. This is perhaps caused by use of aa both as an input stream as well as output stream.

[ad_1] Variables are concepts in the C++ abstract machine that may or may not have a concrete counterpart in your computer. The not-so-closely guarded secret is that C++ abstract machines are not easy to come by (they’re abstract!), so instead we use some very smart tools, the compilers, to emulate the behaviour of a C++ … Read more
