I am trying to get data from other website using NuGet but its not get anything.
var aTags showing null value.
var getHtmlWeb = new HtmlWeb();
var document = getHtmlWeb.Load("https://www.google.com");
var aTags = document.DocumentNode.SelectNodes("//a");
int counter = 1;
if (aTags != null)
{
foreach (var aTag in aTags)
{
Label1.Text += counter + ". " + aTag.InnerHtml + " - " + aTag.Attributes["href"].Value + "\t" + "<br />";
counter++;

I want to display Agendas from table "tblAgenda" using Asp.net here is the query:
public static List<int> SelectByYear()
{
DbManager db = new DbManager();
try
{
List<int> list = new List<int>();
var result = from p in db.tblAgenda
group p by p.News.Value.Year
into g
select new { Year = g.Key, Releases = g };
foreach (var obj in result)
{
list.Add(obj.Year);

list.Reverse();
return list.ToList<int>();

now the issue is I am getting no values in list1, I have tried using the debugger on the query and found that I can't access the "tblAgenda", its giving an error that: " Function evaluation disabled because a previous function evaluation timed out. You must continue execution to reenable function evaluation". I have searched alot but didn't find anything good, my connection string is totally fine because all the other tables are working fine even in "tblAgenda" I can store new agenda from admin panel but I can't retrieve the agendas on front end, what is the issue here?
Thanks.
I have tried rewriting this query a few different ways, but with no luck. Help here is much appreciated.
function createWaterBodyDropDown(region) {
var query = "SELECT 'LAKE_NAME' FROM 1IfQgRAeKPbVJwEpAnqqpYlN8sgiPMg1VQ_RyArI WHERE 'REGION'=" + '"' + region + '"';
var queryText = encodeURIComponent(query);
var gvizQuery = new google.visualization.Query(
'http://www.google.com/fusiontables/gvizdata?tq=' + queryText);
//Send query and draw table with data in response
gvizQuery.send(function (response) {
var str;
var numRows = response.getDataTable().getNumberOfRows();
var numCols = response.getDataTable().getNumberOfColumns();
var name = [
'<label style="font-weight:bolder;font-size:16px">Water body: </label>' + '<select id="waterbody_menu" style="font-size:16px;" onchange="select_waterBody(this.options[this.selectedIndex].value);">' + '<option value="">--All--</option>'
];
for (var i = 0; i < numRows; i++) {
var val = response.getDataTable().getValue(i, 0);
name.push("<option value=" + "'" + val + "'" + ">" + val + "</option>");
}
name.push('</select>');
document.getElementById('waterBody_container').innerHTML = name.join('');
});
}
Your column names have no special characters so they don't need to be quoted, though they could be (with single quotes). String values must be quoted with single quotes. See the reference manual for more details.
So:
SELECT LAKE_NAME FROM 1IfQgRAeKPbVJwEpAnqqpYlN8sgiPMg1VQ_RyArI WHERE REGION = 'foobar'
My multiple image upload code works fine. But while inserting the image path url in the database only one image path is saved. How can i save all the image path url's at once.
Here is my GetPictureData()
public string GetPictureData()
{
string retFileName = "";
try
{
if (((FileUpload1.PostedFile != null)))
{
if ((FileUpload1.PostedFile.ContentType.ToUpper().Contains("IMAGE")))
{
HttpFileCollection hfc = Request.Files;
for (int i = 0; i < hfc.Count; i++)
{
HttpPostedFile hpf = hfc[i];
if (hpf.ContentLength > 0)
{
//Stream inStream = hpf.InputStream;
//byte[] fileData = new byte[hpf.ContentLength];
//inStream.Read(fileData, 0, hpf.ContentLength);
String sTimeStamp = GetTimeStamp();
string iFileName = System.IO.Path.GetFileName(hpf.FileName);
string newFileName = iFileName.Replace(" ", "_");
string OutFile = Server.MapPath(ConfigurationManager.AppSettings["LocalImageDirectory"]) + "\\" + sTimeStamp + "_" + newFileName;
hpf.SaveAs(OutFile);
OutFile = ConfigurationManager.AppSettings["LocalImageDirectory"] + "\\" + sTimeStamp + "_" + newFileName;
retFileName = OutFile;
}
}
}
}
}
catch(Exception ex)
{
string msg = ex.Message;
Response.Write(msg);
}
return retFileName;
}
and here is my UploadButton code
protected void btnUpload_Click(object sender, EventArgs e)
{
if (Session["localauctionid"] != null && Session["localauctionid"].ToString() != "")
{
string filepath = GetPictureData();
if (filepath != "")
{
string sqlcommand = " insert into auctionimages (auctionid, ImagePath, GalleryPic) values(" + Session["localauctionid"].ToString() + ",'" + filepath + "', 0);" +
" update auctionstep1 set ListingStatus = 'Photographed' where auctionid = " + Session["localauctionid"].ToString() + " and (listingstatus <> 'Created' AND listingstatus <> 'Saved');";
Database db = DatabaseFactory.CreateDatabase();
DbCommand cmd = db.GetSqlStringCommand(sqlcommand);
db.ExecuteNonQuery(cmd);
LoadImages();
}
}
}
Thanks
You error lies in the fact that the GetPictureData loops over a collection of files, but only the last file is returned to the button event where you call the save to database code. Of course, only the last file will be saved in the database.
The workaround is to create a standalone method to save in the database where you pass the filename and the localAuctionID. You call this method inside the GetPictureData (renamed more correctly to SavePictureData) internal loop for each file to be saved
As a pseudocode (not tested)
private void SaveToDb(int localAutID, string filepath)
{
string sqlcommand = " insert into auctionimages (auctionid, ImagePath, GalleryPic) " +
"values(#auID, #file, 0); " +
" update auctionstep1 set ListingStatus = 'Photographed' " +
"where auctionid = #auID and (listingstatus <> 'Created' " +
"AND listingstatus <> 'Saved');";
Database db = DatabaseFactory.CreateDatabase();
DbCommand cmd = db.GetSqlStringCommand(sqlcommand);
DbParameter p1 = cmd.CreateParameter()
{ParameterName="#auID", DbType=DbType.Int32, Value=localAutID};
DbParameter p2 = cmd.CreateParameter()
{ParameterName="#file", DbType=DbType.AnsiString, Value=filepath};
db.ExecuteNonQuery(cmd);
}
And if SavePictureData call it inside the for loop
for (int i = 0; i < hfc.Count; i++)
{
.....
retFileName = OutFile;
SaveToDb(Convert.ToInt32(Session["localauctionid"]), retFileName);
}
if (Session["localauctionid"] != null && Session["localauctionid"].ToString() != "")
{
string filepath = GetPictureData();
if (filepath != "")
{
string sqlcommand = " insert into auctionimages (auctionid, ImagePath, GalleryPic) values(" + Session["localauctionid"].ToString() + ",'" + filepath + "', 0);" +
" update auctionstep1 set ListingStatus = 'Photographed' where auctionid = " + Session["localauctionid"].ToString() + " and (listingstatus <> 'Created' AND listingstatus <> 'Saved');";
Database db = DatabaseFactory.CreateDatabase();
DbCommand cmd = db.GetSqlStringCommand(sqlcommand);
db.ExecuteNonQuery(cmd);
LoadImages();
}
The person only clicks the upload button once - hence only one image being saved.
Personally I would evaluate the way you have coded this. I would move the code you use to save the image to the db into a stand alone method and call it when the image upload is complete in GetPictureData()
I'm trying to research the routed direction using google maps for asp.net control. Here is my Code.
GoogleMapForASPNet1.GoogleMapObject.APIKey = ConfigurationManager.AppSettings["GoogleAPIKey"];

GoogleMapForASPNet1.GoogleMapObject.Height = "600px";
GoogleMapForASPNet1.GoogleMapObject.ZoomLevel = 10;
GoogleMapForASPNet1.GoogleMapObject.CenterPoint = new GooglePoint("1", 1.352083, 103.819836);
GoogleMapForASPNet1.GoogleMapObject.ShowTraffic = true;
int count=0;
bool flag = false;
GoogleMapForASPNet1.GoogleMapObject.Points.Clear();
foreach (var gitem in tblG)
{
foreach (var item in tblDT)
{
if (item.Latitude==gitem.Latitude && item.Longitude==gitem.Longitude && flag!=true)
{
count += 1;
GooglePoint GP1 = new GooglePoint();
GP1.ID = "GP" + count.ToString();
GP1.Latitude = Convert.ToDouble(gitem.Latitude);//latitude;
GP1.Longitude = Convert.ToDouble(gitem.Longitude);
GP1.InfoHTML = " Name:<b>" + Name + "</b></br>Point:<b>" + "GP" + count.ToString() + "</b></br>Time:<b>" + gitem.CDate.ToString() + "</b></br>";//stime;
GoogleMapForASPNet1.GoogleMapObject.Points.Add(GP1);
string address = gitem.Latitude + "," + gitem.Longitude;
GoogleMapForASPNet1.GoogleMapObject.Directions.Addresses.Add(address);
flag = true;
}
}
flag = false;
}
I want it as Routed Direction is only between start and End point.
But I got result look like driving Direction. I don't want to get that result. How to fix that problem?
I've been given working ASP code which I have to change in order to update existing data in database insted of creating new entries. I think I should swap INSERT INTO statment with UPDATE but the code is a bit too coplicated for me to figure out where and what to change.
Here it comes:

// set the form action variable
