Unable to get stored memcached client value
this does not retrive the value of TEST , what is the wrong in this code?
Console.Out.WriteLine("START:");
var cfg = new MemcachedClientConfiguration();
cfg.AddServer("127.0.0.1", 11211);
cfg.Protocol = MemcachedProtocol.Binary;
//cfg.SocketPool.MinPoolSize = 10;
//cfg.SocketPool.MaxPoolSize = 50;
//TimeSpan ts = new TimeSpan(0, 10, 0);
//cfg.SocketPool.ConnectionTimeout=ts;
//cfg.SocketPool.DeadTimeout = ts;
//cfg.SocketPool
//var m = new MemcachedClient(cfg);
MemcachedClient client = new MemcachedClient(cfg);
client.Store(StoreMode.Set, "Test2", "Hello World");
//Get a string
//var myVal = client.Get<string>("Test2");
string str = client.Get("Test2") as string;
if (str != null)
{
Console.Out.WriteLine("Fetched item with key: mystring, value: " + str);
}
I found the solution , before run this code i would have installed the memcached.exe

I am getting an array of object json encoded from an api and i would like to display an the each row of objects on a new line
var me3 = jsondata["message"];
for (var i = 1; i < me3.length; i++)
me3.forEach((element) => print(element));
Set<String> set = Set.from(me3);
set.forEach((element) => premiumList
..add(Property(propertyName:"Company : $element[1]", propertyLocation:"SSN : 3001245" )));
The aim is to display each record on a new property sheet and display the the tradename value in each row ..
Using StringBuffer we print
var responseFromAPI = ["test1", "test2", "test3", "test4"];
String _errorMessage = "";
StringBuffer sb = new StringBuffer();
for (String line in responseFromAPI) {
sb.write(line + "\n");
}
_errorMessage = sb.toString();
print(_errorMessage);

I am using C# webmethod to provide data to Google line chart. However I am stuck with the format of the data.
Currently I can only send data in list (object) format. But I want to send data in other format.
Is this possible? Please find my code snippet below:
ASP Page
//call to get data from ASP web method
$.ajax({
type: "POST",`enter code here`
contentType: 'application/json',
data: '{}',
url: 'AdminDashboard.aspx/GetChartData',
beforeSend: function () { alert("before send"); },
complete: function () { alert("complete"); },
success: function (data) {
var linedata1 = new google.visualization.arrayToDataTable(data.d);
linedata1.insertColumn(0, 'date', linedata1.getColumnLabel(0));
// copy values from column 1 (old column 0) to column 0, converted to Date
for (var i = 0; i < linedata1.getNumberOfRows() ; i++) {
var val = linedata1.getValue(i, 1);
if (val != '' && val != null) {
var dateArray = val.split('/');
var year = dateArray[2];
var month = dateArray[0] - 1; // convert to javascript's 0-indexed months
var day = dateArray[1];
linedata1.setValue(i, 0, new Date(year, month, day));
}
}
// remove column 1 (the old column 0)
linedata1.removeColumn(1);
dashboard.bind(programmaticSlider, programmaticChart);
dashboard.draw(linedata1);

Please help me with this.
1. My basic requirement is to create a datatable/or any other format with dynamic columns and then bind the data to google mutli-line chart.
For clarity, my current data format i.e list data is as
Date Open Closed InProgress
1/2/13 2 0 0
2/2/13 1 2 0
3/3/13 0 0 1
4/3/13 0 1 0
You can serve the data in many formats (JSON, CSV, TSV, HTML), I strongly recommend to you to use JSON, you can see the Google default structure here:
I got it working by using the JSON format.
i have posted the snippet, might help some one.
//for dynamic data binding
string jsonData = #"{ ""cols"" :[ { ""label"" : ""Type"" , ""type"" : ""string"" },{ ""label"" : ""Count"" , ""type"" : ""number"" }], ""rows"" :[{""c"":[{""v"":""Mushrooms""},{""v"":3}]}," +
#"{""c"":[{""v"":""Total""},{""v"":1}]}," +
#"{""c"":[{""v"":""Open""},{""v"":1}]}," +
#"{""c"":[{""v"":""Closed""},{""v"":1}]}," +
#"{""c"":[{""v"":""In-Progress""},{""v"":2}]}]}";
The catch was to use "double quotes" for every value. JSON recognizes "double quotes".
Thanks
Been playing with Lucene.NET the last two days.
After reading up on Dates, I was led to believe that Dates are best converted to Milliseconds, and stored in NumericField, with Indexing=true, and Store=No.
But now nothing ever returns - it must be something basic, but I'm just not seeing it.
The saving code is as follows:
...
else if (type == typeof (DateTime?))
{
var typedValue = (DateTime?) value;
field = numericField = new NumericField(documentFieldName, 4, Field.Store.YES, true);
long milliseconds = typedValue.HasValue?(typedValue.Value.Date.Ticks/TimeSpan.TicksPerMillisecond):0;
numericField.SetLongValue(milliseconds);
doc.Add(numericField);
}
...
else
{
field = stringField = new Field(
documentFieldName,
(value != null)?value.ToString():string.Empty,
Store.YES,
Field.Index.ANALYZED) ;
doc.Add(stringField);
}
// Write the Document to the catalog
indexWriter.AddDocument(doc);
When I query for docs against the values saved in Field ... no problem.
When I query for documents by matching against the values in NumericFields, nothing returns.
Where did I go wrong?
Thanks for your help.

So, I have a method that converts entities into a DataTable. The only problem is it is very slow. I made sure to call .ToList() on the IQueryable to make it go ahead and load before processing the results into a DataTable. It takes hardly any time to load the 3000+ rows into memory. However, the real time slayer is in the following iteration in the method:
foreach (var index in imgLeaseIndexes)
{
DataRow dataRow = dataTable.NewRow();
dataRow["StateCode"] = index.StateCode;
dataRow["CountyCode"] = index.CountyCode;
dataRow["EntryNumber"] = index.EntryNumber;
dataRow["Volume"] = index.Volume;
dataRow["Page"] = index.Page;
dataRow["PageCount"] = index.ImgLocation.PageCount;
dataRow["CreateDate"] = index.ImgLocation.CreateDate;
dataTable.Rows.Add(dataRow);
}
And here is the complete method, for what it's worth:
private DataTable buildImgLeaseIndexDataTable(List<ImgLeaseIndex> imgLeaseIndexes)
{
var dataTable = new DataTable();
var dataColumns = new List<DataColumn>();
var tdiReportProperties =
new List<string>() { "StateCode", "CountyCode", "EntryNumber", "Volume", "Page", "PageCount", "CreateDate" };
Type imgLeaseIndexType = imgLeaseIndexes.FirstOrDefault().GetType();
PropertyInfo[] imgLeaseIndexPropertyInfo = imgLeaseIndexType.GetProperties();
dataColumns.AddRange(
(from propertyInfo in imgLeaseIndexPropertyInfo
where tdiReportProperties.Contains(propertyInfo.Name)
select new DataColumn()
{
ColumnName = propertyInfo.Name,
DataType = (propertyInfo.PropertyType.IsGenericType &&
propertyInfo.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>)) ?
propertyInfo.PropertyType.GetGenericArguments()[0] : propertyInfo.PropertyType
})
.ToList());
Type imgLocationType = imgLeaseIndexes.FirstOrDefault().ImgLocation.GetType();
PropertyInfo[] imgLocationPropertyInfo = imgLocationType.GetProperties();
dataColumns.AddRange(
(from propertyInfo in imgLocationPropertyInfo
where tdiReportProperties.Contains(propertyInfo.Name)
select new DataColumn()
{
ColumnName = propertyInfo.Name,
DataType = (propertyInfo.PropertyType.IsGenericType &&
propertyInfo.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>)) ?
propertyInfo.PropertyType.GetGenericArguments()[0] : propertyInfo.PropertyType
})
.ToList());
dataTable.Columns.AddRange(dataColumns.ToArray());
foreach (var index in imgLeaseIndexes)
{
DataRow dataRow = dataTable.NewRow();
dataRow["StateCode"] = index.StateCode;
dataRow["CountyCode"] = index.CountyCode;
dataRow["EntryNumber"] = index.EntryNumber;
dataRow["Volume"] = index.Volume;
dataRow["Page"] = index.Page;
dataRow["PageCount"] = index.ImgLocation.PageCount;
dataRow["CreateDate"] = index.ImgLocation.CreateDate;
dataTable.Rows.Add(dataRow);
}
return dataTable;
}
Does anyone have ideas on how I can make this more efficient and why it is so slow as is?
UPDATE:
I removed the reflection and explicitly set the data columns at compile time per the feedback I've received so far, but it is still really slow. This is what the updated code looks like:
private DataTable buildImgLeaseIndexDataTable(List<ImgLeaseIndex> imgLeaseIndexes)
{
var dataTable = new DataTable();
var stateCodeDataColumn = new DataColumn();
stateCodeDataColumn.ColumnName = "StateCode";
stateCodeDataColumn.Caption = "State Code";
stateCodeDataColumn.DataType = typeof(Int16);
dataTable.Columns.Add(stateCodeDataColumn);
var countyCodeDataColumn = new DataColumn();
countyCodeDataColumn.ColumnName = "CountyCode";
countyCodeDataColumn.Caption = "County Code";
countyCodeDataColumn.DataType = typeof(Int16);
dataTable.Columns.Add(countyCodeDataColumn);
var entryNumberDataColumn = new DataColumn();
entryNumberDataColumn.ColumnName = "EntryNumber";
entryNumberDataColumn.Caption = "Entry Number";
entryNumberDataColumn.DataType = typeof(string);
dataTable.Columns.Add(entryNumberDataColumn);
var volumeDataColumn = new DataColumn();
volumeDataColumn.ColumnName = "Volume";
volumeDataColumn.DataType = typeof(string);
dataTable.Columns.Add(volumeDataColumn);
var pageDataColumn = new DataColumn();
pageDataColumn.ColumnName = "Page";
pageDataColumn.DataType = typeof(string);
dataTable.Columns.Add(pageDataColumn);
var pageCountDataColumn = new DataColumn();
pageCountDataColumn.ColumnName = "PageCount";
pageCountDataColumn.Caption = "Page Count";
pageCountDataColumn.DataType = typeof(string);
dataTable.Columns.Add(pageCountDataColumn);
var createDateDataColumn = new DataColumn();
createDateDataColumn.ColumnName = "CreateDate";
createDateDataColumn.Caption = "Create Date";
createDateDataColumn.DataType = typeof(DateTime);
dataTable.Columns.Add(createDateDataColumn);
foreach (var index in imgLeaseIndexes)
{
DataRow dataRow = dataTable.NewRow();
dataRow["StateCode"] = index.StateCode;
dataRow["CountyCode"] = index.CountyCode;
dataRow["EntryNumber"] = index.EntryNumber;
dataRow["Volume"] = index.Volume;
dataRow["Page"] = index.Page;
dataRow["PageCount"] = index.ImgLocation.PageCount;
dataRow["CreateDate"] = index.ImgLocation.CreateDate;
dataTable.Rows.Add(dataRow);
}
return dataTable;
}
Any ideas on what else might be causing this?
UPDATE 2:
So it looks like other people have had this problem - specific to creating and setting the DataRows. My co-worker came across this:
The DataRow value setter is slow!
I'm going to try some of the stuff suggested in the link.
As Thiago mentioned in the comments the problem is the use of reflection.
The reflection part is where you are using PropertyInfo. You are getting the structure of the data types at runtime. But these are known at compile time.
