View 2 RepliesI'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")

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.
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 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?
View 10 RepliesIn 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);
Based on below code, how to convert the data ? For the UnitCost input Data is float.
protected void CalNett_TextChanged(object sender, EventArgs e) {
int GrossWeight = Convert.ToInt32(WMGrossWeight.Text.ToString());
int UnitCost = Convert.ToInt32(WMUnitCost.Text.ToString());
decimal NettWeight = (GrossWeight - 85);
decimal TotalCost = (NettWeight * UnitCost);
if (WMItem.SelectedValue == "SW.307.004 ")
this.WMTotalCost.Text = TotalCost.ToString();
}
Using the following quires, for select and Update,. Select qry is working fine ,but update qry throws 'conversion failed when converting datetime from character string' .

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.
View 4 RepliesI have a problem in my application. I have deployed application on server. i have a string in dd/mm/yyyy format. to which when i am trying to parse in datetime it is working fine on my server when i am working locally on server. but when i am trying it remotely(client) it is giving exception saying string is not recognized as valid datetime format. This is how i am trying the code.

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);
I inherited some project which uses crystal reports. The datasource for startdate is in string format but I would like to make it up so that the time does not get added. Should I change the sql query somehow or can I make from the object in crystal reports (IFieldObject) to something more manageable.
View 2 RepliesJust 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.
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.

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"?

And here is the related code. When I debugged this code, "dic" only looped through the 3 column names, but did not look into row values which are stored in "dt", the Data Table.
public static string AppendDataCT(DataTable dt, Dictionary<string, string> dic)
{
if (dic.Count != 3)
throw new ArgumentOutOfRangeException("dic can only have 3 parameters");
string connString = ConfigurationManager.ConnectionStrings["AW3_string"].ConnectionString;

using (SqlCommand cmd = conn2.CreateCommand())
{

cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = conn2;
foreach (string s in dic.Keys)
{
SqlParameter p = cmd.Parameters.AddWithValue(s, dic[s]);
p.SqlDbType = SqlDbType.VarChar;
}
conn2.Open();
cmd.ExecuteNonQuery();
conn2.Close();
errorMsg = "The Person.ContactType table was successfully updated!";
}
}
}
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..
