We Keep Coding

Keep int variables values from dataReader c#

I don't have much experience with C# but I am trying to make a simple windows forms app with personal finances.
So, I have 2 dataReader (I am using the Oracle provider), and the sql (oracle table) commands that select only 2 columns from a table, only with 1 value, mainly income 1 and income2 and the sum of all values from a specific month.
the sql strings look like this:
strSQL_sel_income1 = "select DISTINCT categorie,SUM(suma) from financiar where main_categ='income' and categorie IN ('income1') and EXTRACT(month FROM data)=" + luna_income + " Group by categorie";
strSQL_sel_income2 = "select DISTINCT categorie,SUM(suma) from financiar where main_categ='income' and categorie IN ('Income2') and EXTRACT(month FROM data)=" + luna_income + " Group by categorie";
the "luna_income" value is taken from a combobox where I select a specific month.
The problem is when I try to declare an Int variable from the values I get with data reader and these variables are not kept outside the while statement... dr_income1/2 being the dataReader
if (dr_income1.HasRows)
{
while (dr_income1.Read())
{
label26.Text = dr_income1.GetString(0) + ": " + dr_income1.GetInt32(1) + "\n";
int suma_income1 = dr_incomei1.GetInt32(1);
}
}
else
{
label26.Text = "No info;
}
so, I have two similar data readers and two int variables suma_income1 and suma_income2. If I try to make a sum of them, outside the WhIle codes, I get a zero value. Where should I declare the two variables and how to keep their values?
int suma_income_total = suma_income1 + suma_income2;
label29.Text = "Income total: " + suma_income_total;
The suma_income_total is ZERO!!!
dr_income1 = cm1.ExecuteReader();
dr_income2 = cm2.ExecuteReader();
label26.Text = "";
label28.Text = "";
if (dr_income1.HasRows)
{
while (dr_income1.Read())
{
label26.Text = dr_income1.GetString(0) + ": " + dr_income1.GetInt32(1) + "\n";
int suma_income1 = dr_income1.GetInt32(1);
}
}
else
{
label26.Text = "No info";
}
if (dr_income2.HasRows)
{
while (dr_income2.Read())
{
label28.Text = dr_income2.GetString(0) + ": " + dr_income2.GetInt32(1) + "\n";
int suma_income2 = dr_income2.GetInt32(1);
}
}
else
{
label28.Text = "no info";
}
int suma_income_total = suma_income1 + suma_income2;
label29.Text = "income total: " + suma_income_total;
dr_income2.Close();
dr_income1.Close();

I put some changes in your code. It is not ideal since there are several much simple ways. But it is ok as workaround:
dr_income1 = cm1.ExecuteReader();
dr_income2 = cm2.ExecuteReader();
label26.Text = "";
label28.Text = "";
var suma_income1 =0;
var suma_income2 =0;
if (dr_income1.HasRows)
{
while (dr_income1.Read())
{
label26.Text = dr_income1.GetString(0) + ": " + dr_income1.GetInt32(1) + "\n";
suma_income1 += dr_income1.GetInt32(1);
}
}
else
{
label26.Text = "No info";
}
if (dr_income2.HasRows)
{
while (dr_income2.Read())
{
label28.Text = dr_income2.GetString(0) + ": " + dr_income2.GetInt32(1) + "\n";
suma_income2 += dr_income2.GetInt32(1);
}
}
else
{
label28.Text = "no info";
}
int suma_income_total = suma_income1 + suma_income2;
label29.Text = "income total: " + suma_income_total;
dr_income2.Close();
dr_income1.Close();

Doesn't parse updated row from LinqToSQLDataClass to Database LINQ C# WPF

I'm building an Edit/Update system in my program using Linq in C# WPF.
My problem is that my code does submit to the LinqToSQLDatacontex but doesn't parse it through to the actual Database.
The result of that is that the datarow is updated in Runtime but in fact isn't updated in the actual Database.
this is the code I use for Updating my rows.
private void dgUsers_MouseUp(object sender, MouseButtonEventArgs e)
{
try
{
item = dgUsers.SelectedItem;
this.name = (dgUsers.SelectedCells[0].Column.GetCellContent(item) as TextBlock).Text;
var query =
from t in db.tbl_Users
where t.Name == name
select t;
foreach (var q in query)
{
tbMoreName.Text = q.Name;
tbMoreRights.Text = q.Rights;
tbMoreTag.Text = q.Operatortag;
checkMoreActive.IsChecked = q.Active;
tbMoreCardCode.Text = q.CardCode;
}
var table =
from q in db.tbl_UserProfiles
where q.Userprofile == tbMoreRights.Text
select q;
}
catch (Exception exc)
{
MessageBox.Show("NOPE");
}
}
private void btnSaveUser_Click(object sender, RoutedEventArgs e)
{
switch (saveType)
{
case "Edit":
#region save Edit User
var edit =
(from t in db.tbl_Users
where t.Name == name
select t).First();
MessageBox.Show(edit.Id.ToString() + " " + edit.Name.ToString() + " " + edit.Operatortag.ToString() + " " + edit.Rights.ToString() + " " + edit.Active.ToString());
edit.Id = edit.Id;
edit.Name = tbName.Text;
edit.Operatortag = tbOperatortag.Text;
edit.Rights = cbRights.Text;
edit.Active = checkActive.IsChecked.Value;
edit.CardCode = tbCardcode.Text;
MessageBox.Show(edit.Id.ToString() + " " + edit.Name.ToString() + " " + edit.Operatortag.ToString() + " " + edit.Rights.ToString() + " " + edit.Active.ToString() + " " + edit.CardCode.ToString());
db.SubmitChanges();
#endregion
saveType = "";
break;
}
var refresh =
(from q in db.tbl_Users
select new { Name = q.Name, Rights = q.Rights, Operatortag = q.Operatortag, Active = q.Active, Cardcode = q.CardCode }).ToList();
dgUsers.ItemsSource = null;
dgUsers.ItemsSource = refresh;
MessageBox.Show(refresh[0].ToString() + " " + refresh[1].ToString() + " " + refresh[2].ToString() + " " + refresh[3].ToString() + " " + refresh[4].ToString());
}
I hope that one of you guys can help me.
Thanks in advance!!!

How to convert DateTime? to String directly (in c# linq)

i'm making a web-service where i'm calling data-objects who are created directly through linq, i was wondering, how i can convert DateTime? directly to string?, this, because i can't convert the DateTime? to DateTime and then to string through a variable or a what not, because linq don't let me.
Here's the code:
lista = (from p in db.Acciones
select new ItemAcciones
{
ID_Accion = p.ID_Accion,
FechaHora = p.FechaHora != null ? (DateTime)p.FechaHora : DateTime.Now,
//ShowFechaHora = !String.IsNullOrWhiteSpace(((DateTime)p.FechaHora).ToString("HH:mm")) ? ((DateTime)p.FechaHora).ToString("HH:mm") : DateTime.Now.ToString("HH:mm"),
ID_EmpresaNombre = p.Empresas.EmpresaNombre,
ID_ResponsableNombre = p.Responsables.LoginID,
ID_ContactoNombre = p.Contactos.Nombres + " " + p.Contactos.Paterno + " " + p.Contactos.Materno,
ID_AccionTipoNombre = p.AccionTipos.AccionTipoGlosa,
ID_AccionEstadoNombre = p.AccionEstados.AccEstGlosa,
AccionGlosa = p.AccionGlosa,
ID_Empresa = p.ID_Empresa,
AccionDescripcion = p.AccionDescripcion,
ID_Negocio = (int?)p.ID_Negocio ?? 0,
ID_Contacto = p.ID_Contacto,
ID_AccionTipo = p.ID_AccionTipo,
ID_AccionEstado = p.ID_AccionEstado,
ID_ProgFecha = p.ID_ProgFecha != null ? (int)p.ID_ProgFecha : 0,
ShowID_ProgFecha = String.IsNullOrWhiteSpace(p.ID_ProgFecha.ToString()) ?? p.ID_ProgFecha.ToString() : "--/--/----",
//ShowID_ProgFecha = StringAEstilizarComoDate(Convert.ToString(p.ID_ProgFecha)),
ID_ProgHora = p.ID_ProgHora != null ? (int)p.ID_ProgHora : 0,
//ShowID_ProgHora = StringAEstilizarComoHora(Convert.ToString(p.ID_ProgHora)),
ID_EjecFecha = p.ID_EjecFecha != null ? (int)p.ID_EjecFecha : 0,
//ShowID_EjecFecha = StringAEstilizarComoDate(Convert.ToString(p.ID_EjecFecha)),
ID_EjecHora = p.ID_EjecHora != null ? (int)p.ID_EjecHora : 0,
//ShowID_EjecHora = StringAEstilizarComoHora(Convert.ToString(p.ID_EjecHora)),
ID_Responsable = p.ID_Responsable,
EmpresaRUTCompleto = p.Empresas.EmpresaRut.ToString() + "-" + p.Empresas.EmpresaDV,
ID_NegocioNombre = p.Negocios.ProyectoNombre,
}).ToList();
Any question, suggestion or comment to improve the question would be appreciated as well as the answer.

It's a manually solution, but you can use SqlFunctions to handle the string for your Date.
var qqqq = db.YourTable.Select(q => (q.YourDate == null ? "" : (SqlFunctions.DateName("day",q.YourDate) + "/" + SqlFunctions.DateName("month", q.YourDate) + "/" + SqlFunctions.DateName("year", q.YourDate) + " " + SqlFunctions.DateName("hour", q.YourDate) + " " + SqlFunctions.DateName("minute", q.YourDate)))).ToList();
Hope that helps. =)

TFS API - How to obtain the parent of a work item

My ultimate goal is to get the parent of one work item at a time recursively, until there are no more parents in the hierarchy. At the moment, there is nothing recursive yet, I am still at the point of optimizing the way I obtain the parent work item. I have thought of a way of doing this involving a query:
public WorkItem GetParentWorkItem(int id)
{
StringBuilder queryString = new StringBuilder("SELECT [System.Id]" +
" FROM WorkItemLinks " +
" WHERE [Source].[System.WorkItemType] = '" + TFS_TIMESHEET_WORK_ITEM_TYPE + "'" +
" AND [Source].[System.TeamProject] = '" + TFS_TIMESHEET_PROJECT_KEY + "'" +
" AND [Source].[System.Id] = " + id
);
Query wiQuery = new Query(GetWorkItemStore, queryString.ToString());
WorkItemLinkInfo[] wiTrees = wiQuery.RunLinkQuery();
WorkItem wi = GetWorkItemStore.GetWorkItem(wiTrees[1].TargetId);
return wi;
}
The problem with this method is that it gets all the linked work items, including predecessor, successor, child and parents. I knew that wiTrees[1] was the parent work item so I hard coded the index.
I found out a way to get the "parent" WorkItemTypeEnd object from the work item store:
WorkItemLinkTypeEnd linkTypEnd = GetWorkItemStore.WorkItemLinkTypes.LinkTypeEnds["Parent"];
Where do I go from here?

This works on TFS 2013:
var parent_link = work_item.WorkItemLinks.Cast<WorkItemLink> ().FirstOrDefault (x => x.LinkTypeEnd.Name == "Parent");
WorkItem parent_work_item = null;
if (parent_link != null)
parent_work_item = work_item_store.GetWorkItem (parent_link.TargetId);

Found a solution, which returns the parent WorkItem if there is a parent, if not returns null.
public WorkItem GetParentWorkItem(int id)
{
StringBuilder queryString = new StringBuilder("SELECT [System.Id]" +
" FROM WorkItemLinks " +
" WHERE [Source].[System.WorkItemType] = '" + TFS_TIMESHEET_WORK_ITEM_TYPE + "'" +
" AND [Source].[System.TeamProject] = '" + TFS_TIMESHEET_PROJECT_KEY + "'" +
" AND [Source].[System.Id] = " + id
);
Query wiQuery = new Query(GetWorkItemStore, queryString.ToString());
WorkItemLinkInfo[] wiTrees = wiQuery.RunLinkQuery();
int parentLinkId = GetWorkItemStore.WorkItemLinkTypes.LinkTypeEnds["Parent"].Id;
foreach (WorkItemLinkInfo linkInfo in wiTrees)
{
// -2 is the LinkTypeId for parent
if (linkInfo.LinkTypeId == parentLinkId)
{
workItem = GetWorkItemStore.GetWorkItem(linkInfo.TargetId);
break;
}
else
{
workItem = null;
}
}
return workItem;
}

I wrote my own custom parser that will read the script and parse Email from it.here goes the code
If this code can be optimized or can be written more neatly please let me know
private string ReadEmail(string EmailScript)
{
string EncriptedEmail = "";
string dataPart = "";
dataPart = EmailScript.Substring(0, EmailScript.IndexOf("document.write")).Replace("//<![CDATA[\r", "").Replace("\"", "").Replace("\r\n","");
EncriptedEmail = EmailScript.Replace("\"","");
EncriptedEmail = EncriptedEmail.Substring(EncriptedEmail.IndexOf("'> + "), EncriptedEmail.IndexOf(" + </a>") - EncriptedEmail.IndexOf("'> +")).Replace("'> +", "").Trim();
string[] requiredVariables = EncriptedEmail.Split('+');
List<string> ExtractedDataFromRaw = new List<string>();
string email = "";
foreach (string variable in requiredVariables)
{
string temp = dataPart.Substring(dataPart.IndexOf(variable),dataPart.Length-dataPart.IndexOf(variable)).Replace(" ","");
string tempValueofVariable = temp.Substring(0, temp.IndexOf(";"));
tempValueofVariable = tempValueofVariable.Substring(tempValueofVariable.IndexOf("="), tempValueofVariable.Length - temp.IndexOf("=")).Replace("=","");
if (tempValueofVariable.Contains("String.fromCharCode"))
{
tempValueofVariable = GetCharacterFromASCII(tempValueofVariable.Replace("String.fromCharCode(", "").Replace(")", ""));
}
ExtractedDataFromRaw.Add(tempValueofVariable.Replace("'",""));
email += tempValueofVariable.Replace("'", "");
}
return email;
}
private string GetCharacterFromASCII(string value)
{
int result = 0;
int.TryParse(value, out result);
return char.ConvertFromUtf32(result);
}

That code is building the email address one character at a time from character codepoints and then assembling it later. I suppose this is an attempt to prevent email spam. Depending on what you need to do, it might be easiest to just pull the email address from the link using jQuery or something. $('a[href^=mailto]').attr('href').substring(7) or something ought to do it.
