Ensure That Conversion Of A Date To A String And A String To A Date Will Give The Same Date Format?
Jan 16, 2012how 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.

Conversion From Type 'DBNull' To Type 'Date' Is Not Valid
Jul 14, 2011I 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

Jan 10, 2012We 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?
Conversion From Type 'String' To Type 'String' Is Not Valid
Dec 21, 2009I'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".
Find The Closest Valid Date To One Given As An Invalid Date String?
Aug 18, 2010So 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
