I am trying to store a SQL Server datetime into MySQL datetime field, but MySQL stores the date value as all zeros. I use this function to trim the fractional part from the SQL Server datetime, but get the same result when trying to store it in MySQL.
[Code]....
I am trying to get data from mysql database and store in sqlserver database. i am getting the following error
The given value of type MySqlDateTime from the data source cannot be converted to type datetime of the specified target column.
I have a field (varchar) field that holds date. Some data was transferred to this column but the transferred data was a timestamp (datetime in the format of say 10/26/2009 4:54:13 AM). Now, I need to modify the new table to only contain 10/26/2009. How can I write a statement to delete the time leavin gonly 10/26/2009? I can use trim function but the # of characters vary as the date might be 1/10/2010 12:50:00 PM, etc?

I am trying to figure out the best way to convert a string object into a DateTime with only using the year. I have something like:
[Code]....
But it is still giving a "String was not a recognized as a valid DateTime." In the full context, I have a webpage with a formview on it and within the formview is a TextBox control that is taking a user input such as "1999" then an ObjectDataSource picks it up and runs it through a BLL. And within the BLL is where I am trying to convert it before it gets inserted into the database.
Using C# & asp.net
Textbox values are = "04/03/2010"
Format: mm/dd/yyyy
I want to convert the date like this 2010-03-04 instead of 04/03/2010
Format: yyyy-mm-dd
how to make a code for converting this values....
I have a maskededit extender
Code:
TargetControlID="dateTextBox"
Mask="99/99/9999 99:99"
MessageValidatorTip="true"
OnFocusCssClass="MaskedEditFocus"
OnInvalidCssClass="MaskedEditError"
MaskType="DateTime"
[Code] ....
So the input format looks like this 12/23/2012 12:12 AM
And I would like to convert this as datetime so i tried to do
Code:
Dim ab As DateTime
ab = DateTime.Parse(dateTextBox.Text)
But it's showing me an error
Code:
at System.DateTimeParse.Parse(String s, DateTimeFormatInfo dtfi, DateTimeStyles styles)
at System.DateTime.Parse(String s)
at admin_trackadd.saveButton_Click(Object sender, EventArgs e)

I am developing website using ASP.net C# using Mysql.query i have made is:

I am setting up a routine whereby I have to copy the results of a MySQL stored procedure into a DataTable so that I can add fields to the end of the result.
Normally I would convert the Msql DateTime to something that I could more easily manipulate; however, the existing code that I have specifically addresses the MySql DateTime type in too many ways to easily change.
So I thought I could do something like this:
Code:
myDataColumn = new DataColumn("ETD_DT");
myDataColumn.DataType = System.Type.GetType("System.DateTime");
returnDataTable.Columns.Add(myDataColumn);
And substitute "MySqlData.Types.MySqlDateTime" for "SystemDateTime", but it fails with "Column Requires a Valid DataType".
i'm developing a website. i have a registration form where user can registered with this website. this have a birthdate field for store user's birthdate.that is a textbox. here is my code.
[Code]....
I 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
Try
If IsDate(FieldName) Then
Dim actualDate As DateTime = CDate(FieldName)
Dim DtLicExp As DateTime = CDate(actualDate.ToString("d", Thread.CurrentThread.CurrentCulture))
FieldName = DtLicExp.ToString("MM/dd/yyyy")
Return True
End If
Catch ex As Exception
'FieldName &= "Format must be MM/dd/yyyy"
Return False
End Try
End Function
validate this date string formate to datetime.
I want to convert this date "27/03/1985" to datetime.
I am developing a C# VS 2008 / SQL Server 2005 Express website application. I have tried some of the fixes for this problem but my call stack differs from others. And these fixes did not fix my problem. What steps can I take to troubleshoot this?

I created a UserControl and added a public DateTime property. I want to set this property in Markup (ie. <cc1:MyControl runat="server" id="MyControl1" DateTimeProp="1/1/2010" /> ) however I live in a place with a dd/mm/yyyy date format so it complains if I set something like "20/1/2010". Is there a way to set markup in my local datetime format or do I have to conform to "mm/dd/yyyy"?

I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)
I have an XML string which contains Dates formatted "dd/MM/yyyy hh:mm:ss".
I'm loading this XML into a dataset using DataSet.ReadXml().
How can I ensure that this Date is stored in the DataSet as a typed DateTime so that I can Sort, Format and RowFilter on it accordingly.
My test harness is as below:
ASPX Page:
[code]....
obj.From = DateTime.Parse(txtFrom.Text, ci);
And it will give error String was not recognized as a valid DateTime. How it can be solved..
