I am trying the following to select a long date, but becase the value is stored in SQL database as DateTime I am unable to return any results unless minutes and seconds match perfectly...I then tried to use 2 calendars and have the same issue with the DateTime format..
CODE:
I have a datetime for eg:23/9/2009 10:00:00 AM .I want to get date from datetime.Means 23/9/2009 .
View 4 RepliesI have this example and it gives me exception "Conversion from string x to dateTime is invalid"
here is my method to validate Datetime. Example Date string : "27/03/1985"
Public Function validateDateColumn(ByRef FieldName As String) As Boolean
[Code]...
I'm getting date-time from a source as 20110731183330. I want to convert it to '7/31/2011 06:33:30 PM'. Is there a one line code for the same in vb.net?
View 3 RepliesI'm trying to format a datetime field to just show the date. The datetime is bound to an asp:label and for the Text attribute I have tried the following....
Text= String.Format("{0:D}", '<%# Bind("CReviewDate") %>')
and
Text= String.Format("{0:D}", <%# Bind("CReviewDate") %>)
[Code]....
In all cases I get a green wavy line under the equation and the tip help says "Validation (ASP.Net): If this attribute value is enclosed in quotation marks, the quotation marks must match. String.Format("{0:D}", DateTime.Now) is the syntax that I have been told should work.
Ok, just needing a 2nd set of eyes looking at this to make sure the error isn't something else other than my LINQ code here. Here's the function class itself:
Public Function GetJacketByPolicyID(ByVal jacketID As Int32) As tblPolicy
Dim db As New DEVDataContext()
Dim j As tblPolicy = db.tblPolicies.Single(Function(p) p.policyNumber = jacketID)
Return j
End Function
and here is the code which calls this class function in the web control form itself:
Dim p As tblPolicy
Dim j As New Jackets()
p = j.GetJacketByPolicyID(3000050)
For some reason it's flagging the 2nd line in the GetJacketByPolicyID function saying the specified cast is not valid. So I'm guessing it's something I'm doing wrong. I'm sure the tblPolicy/tblPolicies class works right since I can create a new instance of a tblPolicy and set a few variables by hand and return it, so that's not it. I've also checked the datarow I'm fetching and there's no null values in the record, so that shouldn't be it either.
I am using OleDb, trying to do this:
Dim d as Date = DateSerial(Year(rptDate), Month(rptDate), 1 - 1)
Dim conn as OleDbConnection = new OleDbConnection(connStr)
Dim cm as OleDbCommand = new OleDbCommand()
[code]....
I know that d is the same date as the one in SQL server, specifically 3/31/2011 12:00:00 AM.
I need a convert a Date in the Julian format to the complete DateTime format(with date and time with hour,minutes and seconds)

System.Globalization.CultureInfo("en-GB"

I Have this date "27/03/1985" and because it starts with days i can't convert it to datetime.
View 2 RepliesI am trying to store DoteOfBirth from a Calender control in visual studio 2010.

I wanna save like dd/MM/yyyy without anything else but when i save it it shows like

I don't know where to change the format and I don't know how to remove the thing attached to the date. I am writing it in vb.net and saving to xml file.

I am new to working with XML and have a question. I can recover any one value from an XML file but how do I recover 2 values from the same file and align them into a column format.
This is what I have been doing so far:
Dim doc As New System.Xml.XmlDocument
doc.Load("C:a_xmltestingDev_Clean.xml")
Dim list = doc.GetElementsByTagName("product") 'this returns the product ok
Dim list2 = doc.GetElementsByTagName("product_code") 'this returns the product code ok
I can pass either list into this and recover the values but not both
For Each item As System.Xml.XmlElement In list2
Debug.WriteLine(item.InnerText)
Next
Can I pass 2 GetElementsByTagName into a list?
Im using the folowing function to return a SelectList. I need a custom format on Descr, but replacing Key.ToString() to Key.ToString("DD/MM/YY") render me the error "Method 'System.String ToString(System.String)' has no supported translation to SQL.". How could i use a custom date format on Descr?

I have a stored procedure (I cannot edit) that I am calling via linq.
The stored procedure returns values (more complex but important data below):
Customer Stock Item Date Price Priority Qty
--------------------------------------------------------
CUST1 TAP 01-04-2012 £30 30 1 - 30
CUST1 TAP 05-04-2012 £33 30 1 - 30
CUST1 TAP 01-04-2012 £29 20 31 - 99
CUST1 TAP 01-04-2012 £28 10 1 - 30
I am trying to limit this list to rows which have unique Dates and unique quantities in LINQ. I want to remove items with the HIGHER priority leaving rows with unique dates and qty's.
I have tried several group by's using Max and order by's but have not been able to get a result.
Is there any way to do this via linq?
EDIT:
Managed to convert brad-rem's answer into VB.net.
Syntax below if anyone needs it:
returnlist = (From p In returnlist
Order By p.Qty Ascending, p.Priority
Group By AllGrp = p.Date, p.Qty Into g = Group
Select g.First).ToList
I want to create a custom date type. I want to allow null values, and return a string to the user if no date if specified.
View 13 RepliesI want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.

example: inside regional date format setting i set "Short date format dd/MMM/yyyy" and inside vb.net program i set "strSQL = strSQL & ",'" & Date(Date.Now.ToString("dd/MM/yyyy")) & "'" ----> working fine. if user changed the regional date format setting to other format like "mm/dd/yy" facing problem during saving record into sql table. error date conversion. It's possible to avoid using computer regional date format from vb.net? or have any other way...
