Web Forms :: ExecuteNonQuery - Conversion Failed When Converting DateTime From Character String

Jun 2, 2012

I'm trying to submit my form into the database but I'm getting this error on the cmd.ExecuteNonQuery() section:

Conversion failed when converting datetime from character string.

I have three date fields (in bold below) and in the database they are set up as datetime (8).

What am I missing:

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim conn As Data.SqlClient.SqlConnection = New Data.SqlClient.SqlConnection("Data Source=cmssolutions.db.9373013.hostedresource.com; Initial Catalog=cmssolutions; User ID=CMSSolutions; Password=CMSMedical1")
If BMItxt.Text = "" Then
BMItxt.Text = "01/01/1900"

Converting String To DateTime

Sep 11, 2010

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.

VS 2010 - Converting String To Datetime

Nov 18, 2011

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)

Web Forms :: What Is The Correct Format For A DateTime String

Jun 22, 2010

In a simple ASPX page, I have an SqlDataSource and a DataList control bound to it.It shows 3 columns; UserName, DateTimeStamp, and Comment.The database table has these defined as nvarchar(24), datetime, and nvarchar(80).The UserName and DateTimeStamp are shown in the ItemTemplate as Labels, while the Comment is a multiline TextBox.I have an event handler for the OnTextChanged for the Comment so that I can update the table as soon as the user tabs off the TextBox.I use the UserName and DateTimeStamp as the Primary Key, and pass all 3 to a stored procedure, where the parameters are declared the same types as the table.What I'm getting though is an "Input string was not in the correct format", which can only be the DateTime that I am passing.

I've tried different date/time formats, but so far come up empty as to the one that will actually work from the C# code.All the different formats I've tried work fine if I pass them to the SP directly via Management Studio, but all throw an error when I use

SqlDataSource.UpdateParameters.Add("DateTimeStamp", System.Data.DbType.DateTime, lblDateTimeStamp.Text);

Datetime Formatting With String.format

Sep 23, 2010

I have a table in my SQL DB that is a DateTime table, what I want to do is take the numeric datetime it stores and convert it to a long date (i.e. 12/12/2012 conversts to December 12, 2012). Seaching the forums it looks like the string.format is the way to go and searching for info on that I found [URL] which lists all the different formats but they do not list a formating string to convert to the format I want to use. Does anyone know what format string I would use to convert a numeric date to a long date like I want? And can you show it in a code example because I am not 100% sure I understand the code examples shown on that site.

C# - Convert String To Specific DateTime Format?

Jul 30, 2010

I've been googling for a while now and for the life of me can't seem to find a solution. I thought this would be easy but it's taking too long and am turning to stackoverflow.

I need to convert a string which contains a date and time to a DateTime variable. I've formatted the string in the exact format I want to store it in but when i convert it to a DateTime it keeps adding the seconds which I don't want. I want it stored as 01/01/2010 09:00AM. Here's the code I've been using so far:

DateTime.ParseExact(startTime,"MM/dd/yyyy hh:mmtt", null);

C# - Format DateTime String Representation In GridView Dataset

Dec 3, 2010

Just looking for some strategies to modify the typical

mm/dd/yy 00:00:00 to simply
mm/dd/yy of a datetime item being returned in a dataset that is bound to the gridview

the item is within a dataset and I am simply doing the following

gridview.DataSource = GetDataSet();
gridview.DataBind();

So I don't have a ton of interaction with the dataset at the moment. I could brute force iterate through it and do something like

foreach(Table)
foreach(Row)
grab date Col, format and concat to look as desired

but this is very messy and was wondering if there is a more elegant solution.

C# - DateTime.TryParse With Dates Of Yyyy-dd-MM Format / Can Convert String To Date

Jan 17, 2011

I have the following date in string format "2011-29-01 12:00 am" . Now I am trying to convert that to datetime format with the following code:

DateTime.TryParse(dateTime, out dt);

But I am alwayws getting dt as {1/1/0001 12:00:00 AM} , Can you tell me why ? and how can I convert that string to date.

EDIT:

I just saw everybody mentioned to use format argument. I will mention now that I can't use the format parameter as I have some setting to select the custom dateformat what user wants, and based on that user is able to get the date in textbox in that format automatically via jQuery datepicker.
