Re: Looking for a better way to build a Dataset

2-Mar-05 5:03

I have a situation where I need to load 8 key value pairs into a DataSet manually.

The data looks like this:

Mon -- 123.4
Tues -- 232.1
Wed -- 187.4
...
EOW -- 923.6

I have to get these values into a DataSet. Is there a better (less lines of code) way to load it into a DataSet than to create a DataTable manually?

This is what I have so far:

<br />
DataSet ds = new DataSet();   <br />
DataTable dt = new DataTable("MCDVals");<br />
dt.Columns.Add("Legend", typeof(string) );<br />
dt.Columns.Add("Value", typeof(double) );<br />
<br />
DataRow dr = dt.NewRow();<br />
dr("Legend") = "Monday";<br />
dr("Value") = 123.4;<br />
dt.Rows.Add(dr);<br />
<br />
// ... above block repeats another 7 times for the other values<br />
<br />
ds.Tables.Add(dt);<br />

Thanks,
Adam

Just load it into the XML , it is very simple. and you have lots of methods to write , save ...xml using datasets

Like the other's suggested I would use XML also. In your case you are interested in the DataSet.ReadXml() and DataSet.WriteXml() methods. I would:

1) Input all the data by hand into my DataTable and then add that DataTable into a DataSet.

2) Call the DataSet's WriteXml() methods and pass a FileStream into it so you will end up with a file.

3) Now you can use that file as a template to manually change the Value tags in there.

4) When you are done with changing your Value tags you can call the DataSet's ReadXml() method, with another FileStream, to take all your data in the XML file and put it inside a DataTable and a DataSet.

Hi,

Can anyone tell me a way to put my Application on to a web, This is right now a stand alone application with forms ,button ,tab controls ..etc , how do i make this web enabled.

I have tried to put the code under wwwroot on IIS and created a simple html file with a button to invoke my .exe file directly , but it throws an expection for security breach, then i have removed all the security issues and tried, then i get different error.

is there a simple way to move (convert) your stand alone Application to web based

thanks
Samar
