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.

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?

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

I tried using Int32.Parse or Convert.ToInt32 but still couldn't solve it.Here's my code behind for better comprehension (this doesn't do the trick):
