Error - String Was Not Recognized As A Valid DateTime

May 25, 2011

We have data feed, a file with index values and dates (like the S&P 500, for instance). The dates are represented as YYYYMMDD. The Date.Parse() method doesn't understand this format, of course.I wrote a simple static method on a class to parse this, not a big deal, but it irritates the engineer in me that I can't figure out how to get the IFormatProvider functionality to work. All the examples deal with the FORMATTING step, not the PARSING step.So basically, I want to be able to say:

Dim d as DateTime = Date.Parse("20110522", New CustomFormatter())

and get the correct date value out of the Parse method.

Having implemented the IFormatProvider method on CustomFormatter, the GetFormat() method gets called with a System.Type of DateTimeFormatInfo, but I honestly have no idea what to do from there since all the example deal with formatting, not parsing. It doesn't matter if I return an object (self) or null I simply get "String was not recognized as a valid DateTime."

String Was Not Recognized As A Valid DateTime

Aug 4, 2011

I am trying to parse a date to a datetime picker but this error keeps on appearing "String was not recognized as a valid DateTime" The reason behind this is because the date format of the computer is "MM/dd/yyyy" whereas the date am passing is in this format "dd/MM/yyyy" Here is how I tried resolving the problem:

DTDateReceived.Value = Date.Parse(ListView1.Items.Item(ListView1.FocusedItem.Index).SubItems(7).Text)

The aforementioned error occurs

String Was Not Recognized As A Valid DateTime?

Jun 1, 2011

working with dates is driving me mad I have the following function to parse al datetime strings in my project:

Public Shared Function ToDate(ByVal obj As Object) As DateTime?
If obj = String.Empty OrElse obj Is DBNull.Value Then Return Nothing
Return DateTime.Parse(obj.ToString)
End Function

Most of my date strings on my pc are "yyyy/MM/dd" and it parses fine. However on the server the dates are "dd/MM/yyyy".I tried this but it made no difference:

Public Shared Function ToDate(ByVal obj As Object) As DateTime?
If obj = String.Empty OrElse obj Is DBNull.Value Then Return Nothing
Return DateTime.Parse(obj.ToString, System.Threading.Thread.CurrentThread.CurrentCulture.DateTimeFormat)
End Function

on my pc if I assign DateTime.Now to a textbox I get 2011/05/31 08:02:00 AM for example. On the server I have my project the date displays as 31/05/2011 08:02:00 AM. Now I use objectdatasources to save the values to my database. Yesterday I was getting this error:Cannot convert value of parameter '' from 'System.String' to 'System.DateTime'until I formatted the date value like so:

Me.odsRates.InsertParameters.Add("CreatedDate", rt.CreatedDate.ToString("yyyy/MM/dd hh:mm:ss"))

VS 2008 String Not Recognized As A Valid Datetime?

I'm creating an XML file from values contained in a datatable. When I try to write an XML date value, I receive "String not recognized as a valid datetime. The dates that are stored in the datatable column is in this format "yyyymmdd". I tried to use XmlConvert.ToDateTime but I get a warning about the method being obsolete and I'm not sure what serialization mode I should use. How would I format the date from the datatable to MM/dd/yyyy and write to an XML file?

VS 2010 - String Not Recognized As Valid DateTime

Jun 30, 2011

I am having a major issue understanding why this code runs fine once and then when run a second time causes the "String was not recognized as a valid DateTime." exception. This program loops through folders and subdirectorys and retrieves the file dates from the last modified date of the file , Its only when i click New Report to reset all the values in the settings which clears all object lists and resets all the other values that this issue occurs.

This is the value being passed to this function:
#6/14/2011 4:46:51 PM# (The file inside the subdirectory,s last modified date.)

The function is
Public Sub setFileDate(ByVal fileDate As DateTime)
'Format the datetime from the filedate to a UK culture.
Dim myDateTime As DateTime = DateTime.Parse(fileDate, ukCulture.DateTimeFormat)
'Set the current files date.
dFileDate = myDateTime.Date

Regions / Locales - String Not Recognized As Valid DateTime

Feb 5, 2012

I've been having several problems lately with clients that are using a different Windows Region setting than I am. The error is as follows:
The type initializer for 'InventoryDataTable' threw an exception. ---> System.TypeInitializationException: The type initializer for 'InventoryDataTable' threw an exception. ---> System.FormatException: String was not recognized as a valid DateTime.

The error occurs when users load the application and their region settings do not match my own. The application loads up a dataset and attempts to receive a small amount of data before allowing the user to log in. When this is removed, the problem occurs immediately after the user logs in to the app. I cannot seem to find the proper settings to force the user to use either my Region, or to allow the application to figure it out on it's own...

VS 2008 - Format / Year And DateTime Function Not Recognized

Dec 3, 2009

I recently moved a webservice VB.net project from VS 2005 to VS 2008 and now a conversion I use to create a unique receipt number is no longer working.

The Format() function which is supposedly a Visual basic function gives the error:
'Format' is a type and cannot be used as an expression.

The Year() Function which is also a VB function gives the error:
Name 'Year' is not declared.

The Datetime() Function which is also a VB function gives the error:
'DateTime' is a type and cannot be used as an expression.

The actual code statement remains unchanged between the two web services but VS2005 compiles and VS2008 does not.
Dim julda As Long = CLng(Format(Year(oneRowDon.Item(8)), "0000") _
+ Format(DateTime("d", CDate("01/01/" _
+ Format(Year(oneRowDon.Item(8)), "0000")), oneRowDon.Item(8)) _
+ 1, "000"))

All its supposed to do is, when you click on the OK button it shows a code that is fetched from a database table. (X001). Then when you click on it ober and over again. The number should increase. X002, X003, X004... so on.Here's my code

NET Class Is Recognized In VS Get A 'Type Is Undefined' Error On Build?

Mar 22, 2012

I am working on a VB NET project and had the strangest thing happen.I created a class file(just like a dozen or so I have already created). I wrote in the code to access it. The autocomplete found the class, filled it in and colored it blue, just as it should.But, when I run the app, I get a type is undefined error.

There is nothing in the class yet. And there is really no code to post..it is as straight forward as I described.I tried restarting VS; Deleting and recreating the class; Deleting the class and creating a new one with a different name.

Is there something in the VB NET configuration I can check to see if it is not being added somewhere?

I found the problem. I have 2 projects in one solution. They both share some classes that were trying to use my new classes. When I hit F5, both projects are compiled, and since I hadn't shared the classes with the second project, it errored.

So, now my question is changed; How do I specify to only build the specified Startup Project when debugging?

Dim varWeek As String
If varWeek < 10 Then

Could this be causing the problem as it is trying to see if a String is less than 10 which is an Integer?As I said before as I am unable to see this error in the first place so changing this to an Integer doesn't change anything on my system.
