Code:
http.HandleFunc("/", api.Index)
http.HandleFunc("/list", api.FileList)
http.HandleFunc("/api/upload", api.UploadFile)
http.HandleFunc("/api/delete", api.DeleteFile)
http.Handle("/files", http.StripPrefix("/files/", http.FileServer(http.Dir(settings.FilesPath))))
http.ListenAndServe(":1234", nil)
Result 1:
http://localhost:1234/
http://localhost:1234/list
http://localhost:1234/files
match "/"
api.index (It's wrong for the second and third)
Result 2:
http://localhost:1234/api/upload
http://localhost:1234/api/delete
match "/api/xxx"
api.xxx (It's right)
env:
go 1.13.5 windows/amd64
What should I do to fix this problem?
try to use "/list/" replace "/list"

Please excuse my terrible knowledge of the language - just started looking at it a few hours ago.
I'm trying to understand this code and what it produces but quite unsure. Given that the value of inclusions is 10, why is the output what it is?
seps <- tapply(diff, nonCore, function(x) sort(x)[inclusions])
Outputs
"","x"
"ab",23
"ad",15
The value of diff is
"","x"
"1",31
"2",43
"3",37
"4",22
"5",27
"6",13
"7",24
"8",7
"9",26

"34",27

You should supply the code to construct the vectors diff and nonCore, as it is those who could help you need to do massive edits...
That said, what is happening is that your sorting the combination of the vectors according to ab and and ad. ab matches against the first 20 in diff and ad the last 20. Then you just subset the list that is created with the element number that is given by inclusion.
It's the same as running the function without [inclusion] and doing this afterwards:
sep[[1]][10]
sep[[2]][10]

Hey guys I need to make an application using Qt that reads integers from a text file and creates a 2d plot from it. I figure that I need to transfer the integers from the txt file to an array but I am not sure how to do so.
The file has each integer on its own line. Any help will be appreciated.
Well reading a file line by line and put the contents into a vector shouldn't be that hard. Have a look at the QFile api docs. They have some basic examples there.
std::vector<int> here_are_your_ints;
QFile file("yourFileWithIntegers.txt");
// basic error checking
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
return;
// read the contents line by line
while (!file.atEnd()) {
QByteArray line = file.readLine();
QDataStream ds(line);
int int_in_line = 0;
ds >> int_in_line;
here_are_your_ints.push_back(int_in_line);
}
Searching for a good plotting library? I am using QCustomPlot.

I am creating the function below. The purpose is to take in a user provided variable list from an Access database for use in other functions. I would like users to provide a list separated by commas. I have tried several different methods to loop through the provided variable list but cannot get it to operate correctly. My for loop is problematic.
f.extractVariables<-
structure(function
(dbPath,dbName,table,variables
){
# LOAD LIBRARIES
require(RODBC)
require(xlsx)
setwd(dbPath)
db <- odbcConnectAccess2007(dbName)
for (i in 0:length(variables))
{
dataCollection <- sqlQuery(db, 'SELECT table.variables[[i]]
FROM table;')
}
odbcClose(db)
)
}, ex=function(){
#Positive Test to retrieve specified variables from specified location
dbPath = 'z:/sites/'
dbName = 'oysterSites.accdb'
table = 'tblDataSiteOysterSamplingPlan'
variables= (nwLon, nwLat, neLon, neLat)
No need to use a loop here. You can build your query using paste:
variables= "nwLon, nwLat, neLon, neLat" ## user input string
If use give a list a variables:
variables= c("nwLon", "nwLat", "neLon", "neLat")
variables = paste(variables,collapse=",")
Then you build the query as :
query <- paste(paste("SELECT" ,variables),
"FROM table",sep='\n')
cat(query)
# SELECT nwLon, nwLat, neLon, neLat
# FROM table

UPDATE project_phases p2
SET
p2.ClartiyID = #ClarityID,
p2.Start_date = #start_date,
p2.End_date = #End_date,
p2.Planned_efforts = #Planned_efforts
FROM
WSR.dbo.project_phases p2
INNER JOIN WSR.dbo.tb_Project p1 ON p1.ProjectID=p2.ProjectID
WHERE
ProjectID = #ProjectID
but still the error diplays like object name not found even though that table found
If that is your whole query, why are you linking to tb_Project? It seems like this is only to filter on ProjectID, but this column is in Project_Phases so can't you foget the INNER JOIN and just use:
UPDATE project_phases
SET
ClartiyID = #ClarityID,
Start_date = #start_date,
End_date = #End_date,
Planned_efforts = #Planned_efforts
WHERE
ProjectID = #ProjectID
