Hi!

I have ha promblem with adding items to a DataGridViewComboBoxCell. This is what I am doing.

private void SetUpforDataGridView()
{
dataGridViewSearched.ColumnCount = 5;
dataGridViewSearched.ColumnHeadersDefaultCellStyle.BackColor = Color.Navy;
dataGridViewSearched.ColumnHeadersDefaultCellStyle.ForeColor = Color.White;
dataGridViewSearched.ColumnHeadersDefaultCellStyle.Font =
new Font(dataGridViewSearched.Font, FontStyle.Bold);

dataGridViewSearched.Name = "Users Searched";
dataGridViewSearched.AutoSizeRowsMode =
DataGridViewAutoSizeRowsMode.DisplayedCellsExceptHeaders;
dataGridViewSearched.ColumnHeadersBorderStyle =
DataGridViewHeaderBorderStyle.Single;
dataGridViewSearched.CellBorderStyle = DataGridViewCellBorderStyle.Single;
dataGridViewSearched.GridColor = Color.Black;
dataGridViewSearched.RowHeadersVisible = false;
dataGridViewSearched.Dock = DockStyle.Fill;

DataGridViewComboBoxColumn dataGridViewcombobox = new DataGridViewComboBoxColumn();

dataGridViewSearched.Columns.Add(dataGridViewcombobox);

dataGridViewSearched.Columns[0].Name = "UserId";
dataGridViewSearched.Columns[1].Name = "Förnamn";
dataGridViewSearched.Columns[2].Name = "Efternamn";
dataGridViewSearched.Columns[3].Name = "Legitimation";
dataGridViewSearched.Columns[4].Name = "Yrkesroll";
dataGridViewSearched.Columns[5].Name = "Enheter";
dataGridViewSearched.Columns[5].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

dataGridViewSearched.Columns[0].Visible = false;
dataGridViewSearched.Columns[0].DefaultCellStyle.Font =
new Font(dataGridViewSearched.DefaultCellStyle.Font, FontStyle.Italic);

dataGridViewSearched.SelectionMode =
DataGridViewSelectionMode.FullRowSelect;
dataGridViewSearched.MultiSelect = false;
}

And the I am trying to set the table with an object it works fine with the text propertis but not with the DataGridViewComboBoxCell.

public void BindUserList(List<User> userList)
{
dataGridViewSearched.Rows.Clear();
object[] row = new object[5];

foreach (User p in userList)
{
row[0] = p.UserId;
row[1] = p.FirstName;
row[2] = p.LastName;
row[3] = p.MedicalProfession;
row[4] = p.ProfessionalRole;

dataGridViewSearched.Rows.Add(row);

foreach (var unit in p.UnitActivationPeriods)
{
((DataGridViewComboBoxCell)dataGridViewSearched.Rows[dataGridViewSearched.Rows.Count - 1].Cells[5]).Items.Add(unit.ToString());
}
dataGridViewSearched.Rows[dataGridViewSearched.Rows.Count - 1].Tag = p;

}
labelNumberOfUsers.Text = userList.Count.ToString();
dataGridViewSearched.Refresh();
}

Thanks, Mjelten

Is there a better way to code the second foreach...?

bool blnAccepted = false;
IList<Country> ftList = svc.GetCountryList;
IList<County> CountyList = svc.GetCountyList;

                foreach (Country c in ftList)
                {
                    blnAccepted = false;
                    foreach (County ic in CountyList)
                    {
                        if (ic.County == c.County)
                        {
                            blnAccepted = true;
                            break;
                        }
                    }

                    if (blnAccepted)
                    {
//Do work
                    }
                }

Yes, I would imagine that creating a map of countries to counties would allow you to do a single lookup. I'm not sure I follow your overall logic, but if you're doing this second loop a lot, a lookup in a hashtable will make it quicker. That's assuming you need to lookup a county for a country. If you just want to see if it exists, then keep a sorted list, so you can perform a search on it, faster than looking through the whole list.

If you are using C# 3.X and above, you can use the extension methods of IEnumerable<t>; the one you are looking for is Intersect. So ftList.Intersect(CountyList) gives you a collection of all elements of ftList that are present in CountyList. Hope that helps!

How does this work for different classes? I simplified the code earlier, so this is what I have:

Table Def:
Locations: ID, Description, TypeID, ParentID
LocationType: TypeID, Description

Rows in Location:
1 England 1 0
2 France 1 0
3 London 2 1
4 Hampshire 2 1
5 Dorest 2 1
6 Portsmouth 3 4
6 Paris 2 2
etc....

Rows in LocationType:
1 Country
2 Regions
3 Cities
4 Hospitals
5 Hotels

I now have a hierarchy of locations, each with a specific type.

So how do I use ftList.Intersect(Type) on just the TypeID?
Foreach (ftList.Intersect(TypeID = 2 | 4 | 5 )) ???

For arbitrary filtering, use the Where extension method - you pass in a predicate to that method which can use any of the properties of your object.

I found that rewriting the SQL as a stored procedure was easier to get the hierarchy that I needed

CREATE PROC sp_Hierarchy
(@ParentID int)
AS
BEGIN
WITH _items(ID, ParentID, TypeID, Depth)
AS (
SELECT ID, ParentID, TypeID, 0 AS Depth FROM tblItems WHERE ID = @ParentID
UNION ALL
SELECT t.ID, t.ParentID, t.TypeID, i.Depth + 1 FROM tblItems t JOIN _item i ON t.ParentID = i.ID
)
SELECT * FROM _item
END

Hi all,
i'm using webservice in my form, i called this service dynamicly according to its URL, i want to save its assemply localy to read it from any application rather than load this service everytime as any c# dll.
i use this code to load webservice but its a vb.net code

Dim Client As System.Net.WebClient = New System.Net.WebClient()

Dim Stream As System.IO.Stream
Dim Provider1 As CodeDomProvider

Dim oops As CompilerError
Dim assemblyReferences As String() = New String(4) {"System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll"}
Dim ComPram As CompilerParameters
Stream = Client.OpenRead(URL)
Dim Errors As String = ""
Dim Description As New ServiceDescription
Description = ServiceDescription.Read(Stream)
Dim Importer As ServiceDescriptionImporter = New ServiceDescriptionImporter()
Importer.AddServiceDescription(Description, String.Empty, String.Empty)
Importer.ProtocolName = "Soap"

Importer.Style = ServiceDescriptionImportStyle.Client
Importer.CodeGenerationOptions = Xml.Serialization.CodeGenerationOptions.GenerateProperties
Dim nmspace As CodeNamespace = New CodeNamespace()
Dim Unit1 As CodeCompileUnit = New CodeCompileUnit()
Unit1.Namespaces.Add(nmspace)
Dim Warning As ServiceDescriptionImportWarnings
Warning = Importer.Import(nmspace, Unit1)
If (Warning = 0) Then
    Provider1 = CodeDomProvider.CreateProvider("VisualBasic")
    ComPram = New CompilerParameters(assemblyReferences)

If you're calling a webservice you won't have access to its compiled DLL, it is stored on the webserver.

The code provided in the link is working perfectly fine.
You only have to clear the Temp Files folder and rebuilding Web Site again. Hope this will solve the problem

Hi all,
I want to get conversion of this format 'Mon Jun 08 15:19:42 CEST 2009' to DateTime type.
I explain the problem i'm reading from RSS feed but some of them bring that format of datetime, so my code

m_pubDate = Convert.ToDateTime(DirectCast(xNode.Element("pubDate").Value, String))
Broke for RSS Feeds that bring that format and i'm not able to convert this to DateTime.
Thank you for help

Try DateTime.ParseExact?

If you are getting the values in different formats, you may need to use a Regular Expression to determine which format each one uses.

[SOLVED] Process ID

22-Jun-09 22:36

Hi all,

I want to find the process ID, on one of my application. I want to do this, because later on I want to kill those process as well. I decide to use the process ID, because my application can run multiple time. Say the notepad. I can open multiple notepad docs and each have separate PIDs.

So I tried this.

Process[] servers = Process.GetProcessesByName("notepad.exe");
for (int index = 0; index < servers.Length; index++)
{
    int id = servers[index].Id;
}

But each time, Process array length is zero. Even I've open multiple notepads.

Can anyone comment on this.

Thanks a lot Smile | :)

I appreciate your help all the time...
