CDate Function Error In IIS 6.0 "Conversion From String "11 Jul 2011 21:10:27" To Type 'Date' Is Not Valid"?

Jan 10, 2012

We are running .NET 2.0 ASMX web services on Windows 2003 server on IIS 6.0. We have migrated a legacy VB 6.0 application to .NET 2.0 application using VB.NET. CDATE function is used at many places and we did not replace that with .NET equivalent date functions. After migration, code was working fine for many years.Recently, we have started encountering issues on our production servers where the below code fails:

CDATE("11 Jul 2011 21:10:27")

Error: Conversion from string "11 Jul 2011 21:10:27" to type 'Date' is not valid."If we perform an iisreset, the same code starts working fine. Could this be due to some recent patch for Windows server/ .NET patch?

Implement String Format To Get Valid Date

Nov 10, 2008

I have a string coming into my app that is in the form of:
"Fri Sep 21 07:17:46 2008 GMT" or
"Fri Sep []3 07:17:46 2008 GMT" ([] is a space)
The tricky thing is the space for the date. I currently split the string and grab what I need to make a valid VB date.

'Receiving a timestamp in the format: Tue Jan 23 19:33:31 2001 GMT
'Split it and grab what we need to make a valid vb date
_element = timeStamp.Split
_dateAndTime = CDate(_element(1) & " " & _element(2) & " " & _element(4) & " " & _element(3))
Return _dateAndTime

I'm running into the problem when the date is a single digit because there is never a 0 on single digit dates. So, when I split the string I get a "" for _element(2) and that's bad. I know workarounds to adapt for this, however, my question is: How to implement the String.Format to manipulate this string as is and make it a valid VB date? How to make VB recognize this string as a valid VB date without a prepending 0 on single dates.

Ensure That Conversion Of A Date To A String And A String To A Date Will Give The Same Date Format?

Jan 16, 2012

how I can ensure that conversion of a date to a string and a string to a date will give me the same date format.

For example:

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim d As Date = Date.Now


I'm actually only interested in the date part as the label text shows so f is more than I want.But also, the day and month are reversed.

I'm getting the error "Conversion from type 'DBNull' to type 'Date' is not valid."here's the line generating the error.

dtReady.Value = dSet.Tables("Db").Rows(Inc).Item("Fixed_Date")

I'm using a date/time picker control and sending the db value to it. I know that the value is null, but I don't understand why the Picker can't be blank. Is there a way to let it be blank? Or should I set up a way to check for nulls and assign today's date or something just in case?

Find The Closest Valid Date To One Given As An Invalid Date String?

Aug 18, 2010

So there's this accounting package at my client that spits out text-based reports with invalid dates, like February 31st or September 31st.The reports are formatted with spaces and mono-spaced fonts. The data that gets parsed out are fed into a more formal local SSRS report, and that's about all you need to know.

What I am interested in fixing is the situation where a date is invalid and can't be converted into a DateTime struct. The date format from the report is "MMM-dd-yy" (e.g. "Feb-30-10"). The date strings need to be fixed before being shown in the formal report. I've seen this done two ways in my time as a developer, and I want to come up with a cleverer way of doing it (if there isn't a built-in way I don't know about).The first bad method (I can't believe I'm even showing you!):

Dim month As Integer = <Parse out the month from the bad date string>
Dim day As Integer = <Parse out the day from the bad date string>
Dim year As Integer = <Parse out the year from the bad date string>
Dim validDate As DateTime

Conversion From Type 'DBNull' To Type 'Date' Is Not Valid

I am getting this exception from the following VB.NET code for only certain months: System. InvalidCastException: Conversion from type 'DBNull' to type 'Date' is not valid.It happens on the line:if CDate(dRow("CompleteDate")).ToString("d") = arrWeekYear(i, 1).ToString("d") Then.If I understand this correctly, then the problem is I am trying to compare some NULL values for CompleteDate to a non-NULL value.However for some of the more recent records, it does not. But I am able to get output from the T-SQL query with same date range and there are no errors; it runs quickly also. And I examined this T-SQL query for both "Date_ Completed" and "Review_Date" NULL values, but either way,"CompleteDate" was always = NON-Null value.So I do not understand how this is happening.[code]When I add this line above the error-causing line above, my report times out for these months.If Not dRow("CompleteDate") Is System.DBNull.Value Then

Convert Excel Date To Sql Server Date Time Format Using ACE Provider?

Jun 24, 2011

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.

The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.

For what it's worth, the relevent part of the query is:
