View 6 RepliesI am currently working on a custom data type, and wanted to implement a = operator.
I data type is a nullable date that returns a string value if date was supplied.
I want to allow the variable to be set like this
Dim nd as New NullableDate nd = Today Does anyone know how this can be done, or can anyone point me in the right direction?
when i am trying this Date.Compare(Format(DateTimePicker1.Value.Date, "dd/MM/yyyy"), Convert.ToDateTime(dr(1))) < 0 it gives an error message as "Conversion from string "23/06/2011" to type 'Date' is not valid."where dr(1) is database field in text format as 29/3/2011 (dd/mm/yyyy) .

AlteredDate = SelectedDay & "/" & SelectedMonth & "/" & SelectedYear would always work defaulting to DD/MM/YYYY before the clean install.

View 3 RepliesI want to to make date format dd/mm/yyyy with access 2003
Dim strdate As string="22/09/2010"
Dim dd1 As New Date
dd1= strdate
I get : Conversion from string "22/09/2010" to type 'Date' is not valid.
conversion of date
if i used -- Date.parse("28/01/2011")
it gives me error as "String was not recognized as a valid DateTime."
so then i modify above code as -- CDate("28/01/2011").it gives me error as "Cast from string "28/01/2011" to type 'Date' is not valid." I used convert.todatetime also date.parseexact but nothing is working..
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:
Code:
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.
Title pretty much says it all. How do I format the date of a dateandtimepicker to insert it into the SQL date datatype?

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?
When I close my form without saving I want to check if the data on my form has changed since the last time I saved the data.This peace of code, which I included at the bottom always worked fine.Except when I compade a DateTimePicker with a null value in the db.Than I get the error "Conversion from type 'DBNull' to type 'Date' is not valid."Probably on this peace of

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
View 2 RepliesWe 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?
I'm in the process of porting an old excel addin that was writen in VBA to VB .NET. The Excel addin interacts with a number of external com objects. The code sorta looks like this:[code...]
What I'm trying to do is read the string from the COM object and get it in durr for use later in my program.
That second line results in the exception posted above. If I try casting with CStr/CType I get the same exception.
The visual studio watch window reports the type of hurr.getString as a "System.__ComObject" whereas the VBA watch window reports the type as "Variant/Object/String".
Microsoft.VisualBasic.Information.TypeName(hurr.getString) says the type is "String".
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
