Following is my xml file called PropertyInfo.xml :-
<?xml version="1.0" encoding="utf-8" ?>
<PropertyInformation>
<locations>
<location name="Bombay">

In above LoadPropertyInfo() method, how to cast DataSet to List<Location> locations before returning "locations" ?
My query APPEARS to not return any results to populate my dropdown list.
public void getColumnList() {
SqlConnection con;
SqlCommand cmd;
SqlDataReader dataReader;
con = new SqlConnection(ConfigurationManager.AppSettings["ConString"]);
cmd = new SqlCommand();
[code]....
following code successfuly puts my CommandText within the DropDownList. If I copy and paste the CommandText straight into SQL server, it indeed returns the names of the columns.
dataReader.Read();
if (dataReader.HasRows) {
while (dataReader.Read()) {
chkbxlstColumn.Items.Add(cmd.CommandText);
}
}
So if my query is correct enough for SQL Server, why can't C# and ASP.NET recognize the results returned and put it into my control?
FYI I've even tried the blow (initially) and it didn't work either.
chkbxlstColumn.DataSource = dataReader;
chkbxlstColumn.DataValueField = "name";
chkbxlstColumn.DataTextField = "name";
chkbxlstColumn.DataBind();
I'm trying to create a web service that uses a dataset called dsPeople, but it doesn't seem to know where it is, and gives me a directive/namespace error underneath it where it occurs. Do I need to declare it somewhere or something?

what I need to do is load a dataset with the most recent record for each item in the database table. Each item has an ID, location ID and date along with some numeric data. the item ID, location ID, and date is referenced in each record of the table. So each item will have multiple records with different dates that could be anything. To make things worse there may be the same item in multiple locations. and each locations items most recent record needs to loaded in to the dateset and then displayed in a data grid. At a later time there will be a location sort as well so only items in a particular location or group of locations will be loaded. More question on the data grid to come.
View 3 Replies View RelatedI'm trying to pass one dataset's result as a variable in another stored procedure and this is what I have so far:
DataSet dsID = StoredProcedures.GetID((int)Session["TypeID"]);
int IDValue = Convert.ToInt32(dsID.Tables[0].Rows[0]["ID"]);
DataSet dsRequest = StoredProcedures.GetRequest(IDValue);
But I get the error: cannot implicitly convert to system.dataset.

How would I go about shrink the duplicate data set from CWorksheetTwo? For CWorksheetTwo has both CUser and CUserEx, and I only need CUserEx, and all other classes are happy with CUser
Since there is no such thing virtual variable what are my choices? In CWorksheetTwo set users to NULL and use another exclusively? Change CSettings variable to template <class T> std::vector<T>users?

I'm making a program to draw a trajectory, was using as a basis the tangent, but when I put 90 degrees, the tangent is very large, so I thought of putting an if (angle == 90) did not use the tangent.
the design is right, but after choosing it 90 degrees it stops to draw.
for example
1-30 degrees - draws
2-45 degrees ---- draws
3 draws -90 degrees ---
4-60 degrees --- not drawing
5 --- 80 degrees --- not drawing

making routine design is presented below:
void Draw() {
glColor3f(1.0, 1.0, 1.0);
glBegin(GL_LINES);
convert(graus);
if (ant){
x=xx;
y=yy;

I am doing a project where i need to develop a C# windows application. I need to receive data in my laptop (windows 7) using BLED 112 Dongle from NRF 8001 which is Bluetooth Low Power. Actually NRF 8001 is connected to a sensor and it is streaming the sensor's data. I need to receive those data using Dongle and save those data.
I tried doing this by using the library provided by 32feet.net but using this i could only discover the device but wasn't able to connect my Dongle to NRF 8001. So i couldn't proceed further and i am stuck since couple of weeks already ....
I already tried searching in the internet but didn't find much info however i recently i got a API for my Dongle in this link
