I have to import some data in my Shipment table from .csv file,but i have problem with imorting DATE.
Here is you can see my generator:
class Shipment extends Generator
{
private String snd_time;
private String dliv_time;
private int deliv_id;
private int post_id;
int d, m, y, rnd;
public Shipment() throws FileNotFoundException, Exception

Here is my ctl file:
LOAD DATA

TRAILING NULLCOLS
(
id,
send_time,
deliv_time DATE "dd/mm/yyyy",
delivery_id DATE "dd/mm/yyyy",
post_id
)
but when i load this ctl file i get this error
Record 4: Rejected - Error on table SHIPMENT, column SEND_TIME.
ORA-01843: not a valid month
I've tried to write my date without 0, but it still doesn't work and i cannot find a solution for my problem

const seconds = 1000000
var now = moment(moment.duration(seconds).asSeconds()).format('Y[y],M[m],D[d],H[h]')
I want to format this seconds to years, months, days,hours,minutes so I am not able to get where I am making mistake how can I get this format in React native
this code might help you
export function formatDate(seconds) {
var d = new Date(seconds*1000),
month = '' + (d.getMonth() + 1),
day = '' + d.getDate(),
year = d.getFullYear();
if (month.length < 2)
month = '0' + month;
if (day.length < 2)
day = '0' + day;
return [day,month,year].join('/');
}
this code will return you dd/mm/yyyy. if you want to return date+time then you simply return
export function formatDate(seconds) {
var d = new Date(seconds*1000)
return d.toLocaleString()
}
if you want to get remains time, day, month and year then you should use this code
function secondsToHms(sec) {
sec = Number(sec);
var y = Math.floor(sec/31536000) //<<years
var w= Math.floor(y*31536000)
var w1=Math.floor(w-sec)
w=Math.floor(Math.abs(w1)/604800)//<<weeks
var d=Math.floor(Math.abs(w)*604800)
var d1=Math.floor(Math.abs(d)-Math.abs(w1))
d=Math.floor(Math.abs(d1)/86400)
d=Math.abs(d) //<<day
var h = Math.floor(d*86400);
h=Math.floor(h-Math.abs(d1))
h=Math.floor(Math.abs(h)/3600)//<<hours
var m = Math.floor(sec % 3600 / 60);//<<minutes
var s = Math.floor(sec % 3600 % 60);//<<seconds
var yDisplay = y > 0 ? y + (y == 1 ? " year, " : " years, ") : "0 year, ";
var wDisplay = w > 0 ? w + (w == 1 ? " week, " : " weeks, ") : "0 week, ";
var dDisplay = d > 0 ? d + (d == 1 ? " day, " : " days, ") : "0 day, ";
var hDisplay = h > 0 ? h + (h == 1 ? " hour, " : " hours, ") : "0 hour, ";
var mDisplay = m > 0 ? m + (m == 1 ? " minute, " : " minutes, ") : "0 minute, ";
var sDisplay = s > 0 ? s + (s == 1 ? " second. " : " seconds. ") : "0 second. ";
return yDisplay + wDisplay + dDisplay + hDisplay + mDisplay + sDisplay;
}
console.log(secondsToHms(1000000))
Using CP-SAT of google or-tools I'm trying to write this constraint:
q >= (50x + 100y + 150z + 200k + 250p + 300v) / (x + y + z + k + p + v)
Where q is a simple integer.
The thing is I need to round the right side of the equation (let's call it expression) as follows:
if(expression < 75) {
expression = 50;
} else if(expression < 125) {
expression = 100;
} else if(expression < 175) {
expression = 150;
} else if(expression < 225) {
expression = 200;
} else if(expression < 275) {
expression = 250;
} else {
expression = 300;
}
So I need to round the expression
(50x + 100y + 150z + 200k + 250p + 300v) / (x + y + z + k + p + v)
So that it gets one of the following values:
{50, 100, 150, 200, 250, 300}
Let's review 2 cases:
Case 1
q = 180 and expression = 176.
Although the condition 180 >= 176 is true, after rounding up 176 to 200 the tested condition should be 180 >= 200 which is false.
So for q = 180 and expression = 176 I would like the condition to return false.
Case 2
q = 210 and expression = 218.
Although the condition 210 >= 218 is false, after rounding down 218 to 200 the tested condition should be 210 >= 200 which is true.
So for q = 210 and expression = 218 I would like the condition to return true.
I got a great answer here for resolving this challenge over a linear expression but now I need to resolve it for a non-linear expression.
Any suggestions?
Let's rephrase
you have an integer variable e with a value between 0 and 300.
You want to round it to the nearest multiple of 50
if you do:
(e div 50) * 50
you will get the max multiple of 50 less or equal to e
(70 / 50) * 50 -> 50
(99 / 50) * 50 -> 50
(102 / 50) * 50 -> 100
To get a round to nearest, you need to add 25 to e before the division
((e + 25) div 50) * 50
Which will do the correct rounding
((70 + 25) / 50) * 50 -> 50
((99 + 25) / 50) * 50 -> 100
((102 + 25) / 50) * 50 -> 100
with the correct or-tools CP-SAT python code:
numerator = model.NewIntVar(...)
model.Add(numerator == 50x + 100y + 150z + 200k + 250p + 300v)
denom = model.NewIntVar(...)
model.Add(denom == 50x + 100y + 150z + 200k + 250p + 300v)
e = model.NewIntVar(0, 300, 'e')
model.AddDivisionEquality(e, numerator, denom)
shifted_e = model.NewIntVar(25, 325, 'shifted_e')
model.Add(shifted_e == e + 25)
multiple_of_fifty = model.NewIntVar(0, 6, 'multiple_of_fifty')
model.AddDivisionEquality(multiple_of_fifty, shifted_e, 50)
result = model.NewIntVar(0, 300, 'result')
model.Add(result = multiple_of_fifty * 50)
if a and b are positive then
a div b >= q
is equivalent to
a >= q * b
now, your example does not specify how to round (nearest or down)
if you want to round down
q * (x + y + z + k + p + v) <= (50x + 100y + 150z + 200k + 250p + 300v)
If you want to round to nearest, you need to add q / 2 in the right place
q * (x + y + z + k + p + v) <= (50x + 100y + 150z + 200k + 250p + 300v + q / 2)
Now, if you want the other direction
a div b <= q
is equivalent to
a <= q * b + q - 1
The rest of the transformation is the same.

I'm trying to convert the function below to VB .NET but I am having issues with the line that reads s+ = (char)....Any help would be appreciated.
private static string GetHexString(byte[] bt)
{
string s = string.Empty;
for (int i = 0; i < bt.Length; i++)
{
byte b = bt[i];
int n, n1, n2;
n = (int)b;
n1 = n & 15;
n2 = (n >> 4) & 15;
if (n2 > 9)
s += ((char)(n2 - 10 + (int)'A')).ToString();
else
s += n2.ToString();
if (n1 > 9)
s += ((char)(n1 - 10 + (int)'A')).ToString();
else
s += n1.ToString();
if ((i + 1) != bt.Length && (i + 1) % 2 == 0) s += "-";
}
return s;
}
Is there a better way to write this function in VB.NET?
This
s += ((char)(n1 - 10 + (int)'A')).ToString();
is the same as
s &= Chr((n1 - 10 + Asc("A")))
I have developed the excel using the Apache NPOI dll using HSSFWORKBOOK. But in my excel having 3 dependent dropdowns one in each other.
Here my question is I am unable to clear the cell value of dependent dropdowns. Let say like dropdown1 have country values and on the selection of this dropdown2 state values got a filter and selected one of the state. Now if I changed the country again able to filter the data but whatever the previous state selection not getting cleared.
code ref:
No, i am just referring the list of columns data from sheet2 to sheet1 using the formulae. below is code ref:
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
//if (i >= MaxRowCount)
//{
// sheet2.CreateRow(1000 + i).CreateCell(1).SetCellValue(ds.Tables[0].Rows[i][1].ToString());
// MaxRowCount += 1;
//}
//else
// sheet2.GetRow(1000 + i).CreateCell(1).SetCellValue(ds.Tables[0].Rows[i][1].ToString());
if (CategoryCount == 250)
{
rownumber = rownumber + 3000;
CategoryCount = 16;
MaxRowCount = 0;
}
DataRow[] DR = ds.Tables[1].Select("LOCATION_ID=" + ds.Tables[0].Rows[i][0].ToString());
int RowCount = 0;
//int rownumber = 1000;
foreach (DataRow d in DR)
{
if (RowCount >= MaxRowCount)
{
sheet2.CreateRow(rownumber + RowCount).CreateCell(CategoryCount).SetCellValue(d[0].ToString());
MaxRowCount += 1;
}
else
{
sheet2.GetRow(rownumber + RowCount).CreateCell(CategoryCount).SetCellValue(d[0].ToString());
}
RowCount++;
}
IName DeptHierarchy_Dept = hssfworkbook.CreateName();
DeptHierarchy_Dept.NameName = "XDeptHierarchy_Dept_SUB" + (XDeptHierarchy_Dept_SUBCount).ToString();
if (CategoryCount / 26 < 1)
DeptHierarchy_Dept.RefersToFormula = "'Template Field Specs2'!$" + ((char)(65 + CategoryCount)).ToString() + "$" + (StartRowNumber + 1) + ":$" + ((char)(65 + CategoryCount)).ToString() + "$" + ((StartRowNumber + 1) + (RowCount == 0 ? 0 : RowCount - 1)).ToString();
else
DeptHierarchy_Dept.RefersToFormula = "'Template Field Specs2'!$" + ((char)(65 + (CategoryCount / 26) - 1)).ToString() + ((char)(65 + CategoryCount % 26)).ToString() + "$" + (StartRowNumber + 1) + ":$" + ((char)(65 + (CategoryCount / 26) - 1)).ToString() + ((char)(65 + CategoryCount % 26)).ToString() + "$" + ((StartRowNumber + 1) + (RowCount == 0 ? 0 : RowCount - 1)).ToString();

You are looking for "Dependent Drop Down Lists". You'll have to be creative for your formula because your row will keep changing.
one approach i can think of is store the list of "Country-capital" on named region some where deep in excel. On selection of country, parse and find the capital from named region and populate your target cell.
Please see the documentation.

i have this code, the first condition is satisfied but it doesn't run the code.
Use Val ()
Without val() its a string comparision.
