Elements ind = table.select("tr:contains(Club information)");
As you can see, I successfully selected the row of the table which contains the text: Club information.
How can I return the row index of this element as I want to use the number for the next search?
Document playerpage = Jsoup.connect("http://en.wikipedia.org/wiki/Diego_Forl%C3%A1n").get();

System.out.println(e);

I am struggling to get past the last line in this code any help will be appreciated:
The error I am getting is "Array is empty: values (line 16, file "Code")". I have double checked the item ID, the spreadsheet ID and that there is data for it to pick up within the correct range. Any pointers or insights...?
function GetFleet() {
var ssDEFECTS = SpreadsheetApp.getActiveSpreadsheet().getSheets()[0];
var rngFLEET = ssDEFECTS.getDataRange();
var values = rngFLEET.getValues();
var FleetList = [];
//Use column 0 and ignore row 1 (headers)
for (var i = 1; i <= values.length; i++) {
var v = values[i] && values[i][0];
v && values.push(v)
}
// Form ID & List ID
var DefectsForm = FormApp.openById('<FORM KEY ID>');
DefectsForm.getItemById(794194842).asListItem().setChoiceValues(FleetList);
};
Nothing is pushed to your array FleetList. Also the coding in your loop is faulty.
Assuming you want to push the first column (not including the header),
try this and see if it works
function GetFleet() {
var values = SpreadsheetApp.getActiveSpreadsheet()
.getSheets()[0].getDataRange()
.getValues();
var FleetList = [];
//Use column 0 and ignore row 1 (headers)
for (var i = 1, len = values.length; i < len; i++) {
FleetList.push(values[i][0])
}
// Form ID & List ID
var DefectsForm = FormApp.openById('<FORM KEY ID>');
DefectsForm.getItemById(794194842)
.asListItem()
.setChoiceValues(FleetList);
};
Have database. Have query with unknown count of columns. Need to put all answer in QList
database = QSqlDatabase::addDatabase("QMYSQL");
...
QString sql = "Select * from test";
QSqlQuery query = QSqlQuery(database);
query.exec(sql);
QList<QStringList> retList;
Use .isValid() on value.
while (query.next()) {
int count = 0;
bool flagValues = true;
QStringList row;
while(flagValues)
{
QVariant value = query.value(count);
if(value.isValid() && !(count == memCount) )
{
count++;
row.append(value.toString());
}
else
{
flagValues = false;
}
}
retList.append(row);
All is ok, but i have a messages (not error) like in every row. :
QMYSQLResult::data: column 3 out of range
I do not want to use additional query (like information_schema) to know columns number.
Use query.record().count() to obtain the number of columns. Thus:
database = QSqlDatabase::addDatabase("QMYSQL");
...
QString sql = "Select * from test";
QSqlQuery query = QSqlQuery(database);
query.exec(sql);
const int memCount = query.record().count();
// query loop goes here
I have the following code:
using (CPASEntities ctx = new CPASEntities())
{
IWorksheet ws = wb.Worksheets[0];
ws.Name = "Summary";
var tsm = (from x in ctx.tblTimesheetMasters
where x.TSID == TSID
select new
{
TimesheetID = x.TSID,
Comments = x.TSComments,
Vendor = x.tblVendor.Vendor_Name,
StartDate = x.TSStartDate,
Author = x.TSAuthor,
Approver = x.TSApprover,
Override_Approver = x.TSOverrideApprover,
Status = x.tblTimesheetStatu.TSStatusDesc
}
).ToList();
SpreadsheetGear.IRange range = ws.Cells["A1"];
// I want to copy the entire tsm list to this range, including headings.
}
As the comment states, I want to put that entire list into the ws worksheet starting at A1. I include the code in case it's easier to use a different construct. FWIW, there will be only one entry...TSID is the primary key. I can, of course, use the .FirstorDefault() construct if that is important. I thought it not important.
Your range is only one cell. You need a range big enough to contain all the cells the list would populate.
To populate your worksheet with the list, you could do something like this.
int iRow = 0;
int iCol = 0;
if (tsm.Count() > 0)
{
foreach (var prop in tsm[0].GetType().GetProperties())
{
ws.Cells[iRow, iCol].Value = prop.Name;
iCol++;
}
iRow++;
foreach (var t in tsm)
{
iCol = 0;
foreach (var prop in t.GetType().GetProperties())
{
ws.Cells[iRow, iCol].Value = prop.GetValue(t, null);
iCol++;
}
iRow++;
}
}
If you want a range, you could add this line.
SpreadsheetGear.IRange range = ws.Cells[0, 0, iRow - 1, iCol - 1];
Having trouble with a list function I wrote using CouchApp to take items from a view that are name, followed by a hash list of id and a value to create a CSV file for the user.
function(head, req) {
// set headers
start({ "headers": { "Content-Type": "text/csv" }});
// set arrays
var snps = {};
var test = {};
var inds = [];
// get data to associative array
while(row = getRow()) {
for (var i in row.value) {
// add individual to list
if (!test[i]) {
test[i] = 1;
inds.push(i);
}
// add to snps hash
if (snps[row.key]) {
if (snps[row.key][i]) {
// multiple call
} else {
snps[row.key][i] = row.value[i];
}
} else {
snps[row.key] = {};
snps[row.key][i] = row.value[i];
}
//send(row.key+" => "+i+" => "+snps[row.key][i]+'\n');
}
}
// if there are individuals to write
if (inds.length > 0) {
// sort keys in array
inds.sort();
// print header if first
var header = "variant,"+inds.join(",")+"\n";
send(header);
// for each SNP requested
for (var j in snps) {
// build row
var row = j;
for (var k in inds) {
// if snp[rs_num][individual] is set, add to row string
// else add ?
if (snps[j][inds[k]]) {
row = row+","+snps[j][inds[k]];
} else {
row = row+",?";
}
}
// send row
send(row+'\n');
}
} else {
send('No results found.');
}
}

Can't say for sure since you gave little detail, however, a probable source of problems, is the use of arrays to collect data from every row: it consumes an unpredictable amount of memory. This may explain why it works when you query for a few records, and fails when you query for all records.
You should try to arrange data in a way that eliminates the need to collect all values before sending output to the client. And keep in mind that while map and reduce results are saved on disk, list functions are executed on every single query. If you don't keep list function fast and lean, you'll have problems.
I am trying to export to excel using Open XML with simple formatting. Export to Excel is working. The problem is with formatting the data. I am trying to have very basic formatting. i.e. the Column names should be in bold and rest of the content in normal font. This is what I did. Please let me know where am I going wrong.

It seems like you are missing a ")" after your first font creation. So then you end opp with only one font index (the default one)
Below is the code I use for exactly what you are asking for.
You might remove fills and borders and remove them from cellformat, but I had some syntax problems while writing this so I just left it when it all worked :-)
private Stylesheet GenerateStyleSheet()
{
return new Stylesheet(
new Fonts(
// Index 0 - Default font.
new Font(
new FontSize() { Val = 11 },
new Color() { Rgb = new HexBinaryValue() { Value = "000000" } }
),
new Font(
new Bold(),
new FontSize() { Val = 11 },
new Color() { Rgb = new HexBinaryValue() { Value = "000000" } }
)
),
new Fills(
// Index 0 - Default fill.
new Fill(
new PatternFill() { PatternType = PatternValues.None })
),
new Borders(
// Index 0 - Default border.
new Border(
new LeftBorder(),
new RightBorder(),
new TopBorder(),
new BottomBorder(),
new DiagonalBorder())
),
new CellFormats(
// Index 0 - Default cell style
new CellFormat() { FontId = 0, FillId = 0, BorderId = 0 },
new CellFormat() { FontId = 1, FillId = 0, BorderId = 0, ApplyFont = true }
)
);
}
