SqlDatasource1 :
Table1
-----------
Result_1
-----------
Result_2
I have a query, and I want to get a Result_2 value from the query in code behind, in the BeforePrint event, and I don´t want to put a label in the report, how can I do this?
Thanks
If you want to manually run the Select command on your data source, you could try something like (C#):
var dv = new DataView()
dv = Sqldatasource1.Select(DataSourceSelectArguements.Empty) as DataView;
if (dv.Count > 0)
{
foreach (DataRowView rv in dv)
{
string Result2Val = rv["Result_2"].ToString();
// do something with the result...
}
}
I'm sure VB will follow a similar pattern.
Alternatively, try and capture the OnSelected event, if it's already being triggered by another control.

I am writing a code which calculate monthly net salary in react but I faced issue NaN. What is my error in this code: ?
There seems to be one of the reason why you are getting NaN is because you have not initialized netSalary, grossSalary and other variables and as a result they are undefined and when you do something like undefined + 1 => you get NaN.
But why are they undefined?
You might think in your function you updated the state variables before using them, but they are not updated instantaneously not synchronously, so after you have written setTaxRates() and if you try to use the state variables at that moment the state variable have not really updated it's value, so you will end up using old value, which will be undefined in this case.
Solution?
First initialize the state variables with some default data.
then in your funciton make sure you do not use state variables just after updating them
so your updated code will look something like this.
const salary()=>{
const [grossSalary,setGross] = useState(0);
const [taxRate, setTax] =useState(0);
const [pension, setPension] = useState(0);
const [netSalary, setNet] = useState(0)
const calSal =()=>{
if(grossSalary > 600 && grossSalary<1651){
let taxR = (grossSalary*0.1)-60;
let penS= grossSalary*0.7
netSal = grossSalary-taxR-pension;
// now update all the states as required
setTaxRate(taxR);
setPension(penS);
setNetSalary(netSal);
}else{
.......
}
.............
}
}

I am developing and Django website, and I have an array of some str values(parts of url).When user is redirect to:
https://www.example.com/something/name/
how can system system knows that that is part of that arry.
I alredy have this:
urlpatterns = [
path(r'<name1>, views.example')
]
And Array:
arr = [name1,name2,name3, ....namen] # elements of array are assigned to variables in for loop.
Thank you in advance.
So you need to change urlpatterns to:
path('<str:name>,views.example)
str is data type, and other data type for this use are:
int – Matches zero or any positive integer.
str – Matches any non-empty string, excluding the path separator(‘/’).
slug – Matches any slug string, i.e. a string consisting of alphabets, digits, hyphen and under score.
uuid – Matches a UUID(universal unique identifier).
And function call to:
views.example(request, name = "name_n") # for better code reading use name_1, name_2, .. name_n instead of name1,name2 etc.
and that would be it, enjoy in Django.

for dateItem in ${times[#]}
do
date2=$(date --date="$dateItem 3 hour ago" +%H:%M:%S)
echo $date2
done
Hi It's worked after doing some changes it works correct,
If you wish todo it without an array
Here it is:
date2=$(date -d "$times 3 hour ago" +"%H:%M:%S")
echo $date2

I'm writing a phonebook application and one of the functions is for searching the phonebook by name.
The program should print out the names the same way as the user entered them (later I will include the numbers and other info). The phonebook has 100 contacts.
sname is the name that user have entered to search.
name[a] is name list. Is there any other code like strstr? Like its operating if its found printing them if not then print("not found any") something like this:
for(a=1; a<101; a++) {
while(strstr(name[a],sname) != NULL) {
printf(strstr(name[a], sname));
}
}
You can do that: it is an infinite loop.
while(strstr(name[a],sname)!=NULL){
printf("%s\n",strstr(name[a],sname));
}
None of a, name[a], sname change in the conditions or body of the while
