I'm using entity framework.
I export a table to excel in this way:
DetailsSet TheDetails = db.DetailsSet.SingleOrDefault(x => x.Id == id);
string filename = Guid.NewGuid() + ".xls";
StringWriter tw = new System.IO.StringWriter();
HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
DataGrid dgGrid = new DataGrid();
// var List = db.GetRegList(TheDetails.CorrectAnswer);
List<RegistrationSet> RegList = TheDetails.RegistrationSet.Where(x => x.Answer == TheDetails.CorrectAnswer).ToList();
dgGrid.DataSource = RegList;
dgGrid.DataBind();
dgGrid.RenderControl(hw);
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
Response.Write(tw.ToString());
Response.End();
The issue is that in the excel, all the text in hebrew from the db is shown like gibresh.
When I remove the .Where(x => x.Answer == TheDetails.CorrectAnswer) from the grid, the excel is OK - means all the texts in hebrew is OK.
Like This is OK:
List<RegistrationSet> RegList = TheDetails.RegistrationSet.ToList();
but like this, is not OK:
List<RegistrationSet> RegList = TheDetails.RegistrationSet.Where(x => x.Answer == TheDetails.CorrectAnswer).ToList();
Full example of OK Function:
DetailsSet TheDetails = db.DetailsSet.SingleOrDefault(x => x.Id == id);
string filename = Guid.NewGuid() + ".xls";
StringWriter tw = new System.IO.StringWriter();
HtmlTextWriter hw = new System.Web.UI.HtmlTextWriter(tw);
DataGrid dgGrid = new DataGrid();
// var List = db.GetRegList(TheDetails.CorrectAnswer);
List<RegistrationSet> RegList = TheDetails.RegistrationSet.ToList();
dgGrid.DataSource = RegList;
dgGrid.DataBind();
dgGrid.RenderControl(hw);
Response.ContentType = "application/vnd.ms-excel";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + filename + "");
Response.Write(tw.ToString());
Response.End();
Response.BinaryWrite(System.Text.Encoding.UTF8.GetPreamble());
Fixed the problem

I have form for upload file and i want to upload thumbnail for the file in the same form I am doing that with this part of code :
var basePath2 = Path.Combine(Directory.GetCurrentDirectory() + "\\Thumbnails\\");
bool basePathExists2 = System.IO.Directory.Exists(basePath2);
if (!basePathExists2)
Directory.CreateDirectory(basePath2);
var thumbnailPath = Path.Combine(basePath2, Thumbnail.FileName);
if (!System.IO.File.Exists(thumbnailPath))
{
using (var stream = new FileStream(thumbnailPath, FileMode.Create))
{
await Thumbnail.CopyToAsync(stream);
}
}
I am saving this model to the database:
var fileModel = new FileUploadViewModel
{
Year = createdOn,
PublishedOn = model.PublishedOn,
FileType = File.ContentType,
Extension = extension,
Name = model.Name,
Description = model.Description,
FilePath = filePath,
Author = model.Author,
ThumbnailPath = thumbnailPath,
};
When I want to show the thumbnail in a view, it doesn't work but in src I have the right path, as you can see in this screenshot:
Screenshot with Source of image
In controller :
string uniqueThumbName = null;
if (Thumbnail != null)
{
string uploadsFolder = Path.Combine(hostingEnvironment.WebRootPath, "Thumbnails");
uniqueThumbName=Guid.NewGuid().ToString() + "_" + Thumbnail.FileName;
string filePath2 = Path.Combine(uploadsFolder, uniqueThumbName);
Thumbnail.CopyTo(new FileStream(filePath2, FileMode.Create));
}
var fileModel = new FileUploadViewModel
{
ThumbnailPath=uniqueThumbName,
};
In View :
var thumbPath = "~/Thumbnails/" + file.ThumbnailPath;
<img style="width:80px;height:80px;" src="#thumbPath" asp-append-version="true" />
i can use elasticsearch 2.3.0 version with C# (Nest)
i want to use the analysis with index,
but index settings doesn't change and i don't know why.
Here's my code:
private void button1_Click_1(object sender, EventArgs e)
{
var conn = new Uri("http://localhost:9200");
var config = new ConnectionSettings(conn);
var client = new ElasticClient(config);
string server = cmb_Serv.Text.Trim();
if (server.Length > 0)
{
string ser = server;
string uid = util.getConfigValue("SetUid");
string pwd = util.getConfigValue("SetPwd");
string dbn = cmb_Db.Text;
string tbl = cmb_Tbl.Text;
setWorkDbConnection(ser, uid, pwd, dbn);
string query = util.getConfigValue("SelectMC");
query = query.Replace("###tbl###",tbl);
using (SqlCommand cmd1 = new SqlCommand())
{
using (SqlConnection con1 = new SqlConnection())
{
con1.ConnectionString = util.WorkConnectionString;
con1.Open();
cmd1.CommandTimeout = 0; cmd1.Connection = con1;
cmd1.CommandText = query;
int id_num =0;
SqlDataReader reader = cmd1.ExecuteReader();
while (reader.Read())
{ id_num++;
Console.Write("\r" + id_num);
var mc = new mc
{
Id = id_num,
code = reader[0].ToString(),
mainclass = reader[1].ToString().Trim()
};
client.Index(mc, idx => idx.Index("mctest_ilhee"));
client.Alias(x => x.Add(a => a.Alias("mcAlias").Index("mctest_ilhee")));
client.Map<mc>(d => d
.Properties(props => props
.String(s => s
.Name(p => p.mainclass)
.Name(p2 => p2.code).Index(FieldIndexOption.Analyzed).Analyzer("whitespace"))));
} reader.Dispose();
reader.Close();
}
IndexSettings Is = new IndexSettings();
Is.Analysis.Analyzers.Add("snowball", new SnowballAnalyzer());
Is.Analysis.Analyzers.Add("whitespace", new WhitespaceAnalyzer());
}
}
}
Well first of all you code is strange.
Why you are doing mapping in while? Do mapping only once.
Its impossible to help you because you are not even providing error you get. I would recomend to add simple debug method.
protected void ValidateResponse(IResponse response)
{
if (!response.IsValid ||
(response is IIndicesOperationResponse && !((IIndicesOperationResponse) response).Acknowledged))
{
var error = string.Format("Request to ES failed with error: {0} ", response.ServerError != null ? response.ServerError.Error : "Unknown");
var esRequest = string.Format("URL: {0}\n Method: {1}\n Request: {2}\n",
response.ConnectionStatus.RequestUrl,
response.ConnectionStatus.RequestMethod,
response.ConnectionStatus.Request != null
? Encoding.UTF8.GetString(response.ConnectionStatus.Request)
: string.Empty);
}
}
All requests such as client.Alias, client.Map returns status. So you can do
var result = client.Map<mc>(.....YOUR_CODE_HERE....)
ValidateResponse(result);
Then you will see two things, propper error which ES return + request which NEST sends to ES
I am exporting to excel using closedxml my code is working fine, but i want to format my exported excel file with a title, backgroundcolour for the title if possible adding image.

I need to export Excel and I'm using MVC4
This is my code
var co = from c in context.AN_COMPANY
orderby c.COMPANY_DESCR
select c;
List<AN_COMPANY_EXT> societa_list = new List<AN_COMPANY_EXT>();
foreach (var o in co)
{
AN_COMPANY_EXT c_ex = new AN_COMPANY_EXT(o);
societa_list.Add(c_ex);
}
GridView gv = new GridView();
gv.DataSource = (from d in societa_list
select new { Codice = d.ID_COMPANY, Descrizione = d.COMPANY_DESCR, SAP_Alias = d.COMPANY_SAP_ALIAS, Booking_Company = d.IS_BOOKING_COMPANY });
gv.DataBind();
Response.Buffer = true;
Response.AddHeader("content-disposition", "attachment; filename=AnagraficaSocieta.xls");
Response.ContentType = "application/ms-excel";
Response.Charset = "";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gv.RenderControl(htw);
Response.Output.Write(sw.ToString());
Response.Flush();
Response.End();
return RedirectToAction("Index");
How can I set column name with a space, for example "SAP ALIAS" instead of SAP_ALIAS?
I could get the handle to the google text doc i needed. I am now stuck at how to read the contents.
My code looks like:
GoogleOAuthParameters oauthParameters = new GoogleOAuthParameters();
oauthParameters.setOAuthConsumerKey(Constants.CONSUMER_KEY);
oauthParameters.setOAuthConsumerSecret(Constants.CONSUMER_SECRET);
oauthParameters.setOAuthToken(Constants.ACCESS_TOKEN);
oauthParameters.setOAuthTokenSecret(Constants.ACCESS_TOKEN_SECRET);
DocsService client = new DocsService("sakshum-YourAppName-v1");
client.setOAuthCredentials(oauthParameters, new OAuthHmacSha1Signer());
URL feedUrl = new URL("https://docs.google.com/feeds/default/private/full/");
DocumentQuery dquery = new DocumentQuery(feedUrl);
dquery.setTitleQuery("blood_donor_verification_template_dev");
dquery.setTitleExact(true);
dquery.setMaxResults(10);
DocumentListFeed resultFeed = client.getFeed(dquery, DocumentListFeed.class);
System.out.println("feed size:" + resultFeed.getEntries().size());
String emailBody = "";
for (DocumentListEntry entry : resultFeed.getEntries()) {
System.out.println(entry.getPlainTextContent());
emailBody = entry.getPlainTextContent();
}
Plz note that entry.getPlainTextContent() does not work and throws object not TextContent type exception
finally i solved it as:
for (DocumentListEntry entry : resultFeed.getEntries()) {
String docId = entry.getDocId();
String docType = entry.getType();
URL exportUrl =
new URL("https://docs.google.com/feeds/download/" + docType
+ "s/Export?docID=" + docId + "&exportFormat=html");
MediaContent mc = new MediaContent();
mc.setUri(exportUrl.toString());
MediaSource ms = client.getMedia(mc);
InputStream inStream = null;
try {
inStream = ms.getInputStream();
int c;
while ((c = inStream.read()) != -1) {
emailBody.append((char)c);
}
} finally {
if (inStream != null) {
inStream.close();
}
}
}
