I am already using Process class to run the executable program. The output files are created by the arguments given to the executable program. I tried to give a different name to the output each time. I am runing the program with the help of a cycle. And the input changes name in each cycle and the output the same. But the only thing it's saved it is the last output. How can I solve this?

How can I build a windows form which contains a table?

I want to write in a Xml file some data, but I have an error because I have the same attribute "ClusterRoute" who appears many times. XmlTextWriter myXmlTextWriter = new XmlTextWriter(@"c:\\Results.xml", Encoding.UTF8); myXmlTextWriter.WriteStartDocument(); for (int i = 0; i < clustersList.Count; i++) { myXmlTextWriter.WriteStartElement("Clusters"); for (int j = 0; j < clustersList[i].Count; j++) { myXmlTextWriter.WriteAttributeString("ClusterRoute", clustersList[i][j].CityID.ToString()); } myXmlTextWriter.WriteEndElement(); } myXmlTextWriter.WriteEndDocument();

that's not my problem. I just want to read the value from a Xml file and to convert it to time, in a string without date.

this is the function which reads the Xml File and is part of a class Cities. public class Cities : List { public void OpenCityList(string filename) { DataSet cityDS = new DataSet(); try { this.Clear(); cityDS.ReadXml(filename); DataRowCollection cities = cityDS.Tables[0].Rows; foreach (DataRow city in cities) { this.Add(new City(Convert.ToInt32(city["X"], CultureInfo.CurrentCulture), Convert.ToInt32(city["Y"], CultureInfo.CurrentCulture), Convert.ToInt32(city["Demand"], CultureInfo.CurrentCulture), Convert.ToString(city["Open"], CultureInfo.CurrentCulture))); } } finally { cityDS.Dispose(); } } private TimeSpan startHour; public TimeSpan StartHour { set { startHour = value; } get { return startHour; } } public void ShowCityHour() { foreach (City cityhour in this) { startHour = cityhour.OpenTime; } } } And in another class, named City I have : public class City { private int demand; private TimeSpan openTime; public City(int x, int y, int citydemand, string open)// I am interested about the string open { Location = new Point(x, y); demand = citydemand; DateTime oTime = DateTime.Parse(open); TimeSpan openTime = oTime.TimeOfDay; } public TimeSpan OpenTime { get { return openTime; } set { openTime = value; } } } It is something like that. I take the data from the Xml file and I store it in the string open, and I want to convert it to time, because after that I will have to sort the whole list in order of the hours.

Thanks for trying to help me, but I dont want to make that. I want only to show the hour I read it from the Xml file. That's the problem, because I tried it and it shows something like 00:00, and not 07:30, like it should.

I read a Xml file and from it I will have a string, for example the string name is open="07:30". I tried to read it like this DateTime oTime = DateTime.Parse(open); TimeSpan openTime = oTime.TimeOfDay; where openTime is of type TimeSpan. But the result is 00:00:00 and it doesnt work.

The problem is that I will take the string from a Xml file and I cant use it like that. I really need help.

But if my string is like this "07:30", what can I do? Because I tried that method and my result is 00:00:00. :doh:

Hi, I have a problem with the conversion of a string of type "07:30" into a time. I want to take only the time, without the date. I tried DateTime openTime = DateTime.Now.ToShortTimeString(open); ,where open = "07:30". Please help me with this problem.

Can someone help me telling me how can I convert a element of a list to int?

How can I convert a value taken from a Xml file into a time value? Please help.
