I have been unable to correctly convert a string to date. The string is read from a text file and placed into a string, below is a snippet of how the text file is read until the date is field is read:
Dim varOrderNo As String
Dim varDate As String
Static Dim currentrow(20) As String
[Code] .....
I have then tried loads of different ways to convert it to a Date so when I then write it to a SQL Database it enters as a date. The string read from the text file is in the format of 13122011. If I don't try to change it to a Date before writing to SQL it doesn't recognise it as a date and sets the field to 01/01/1900. I have tried and searched loads online and everything i try should work but doesn't.
Dim varDateConvert As Date
varDateConvert = CDate(varDate)
varDateConvert = Convert.ToDateTime(varDate)
varDateConvert = DateTime.Parse(varDate)
All of the above cause my program to drop out / crash at the point of the converting.
I have also tried to format the string to insert the '/' before converting:
txtDate.Text = varDate.Substring(0, 2) & "/" & varDate.Substring(2, 2) & "/" & varDate.Substring(4, 4)
varDateConvert = DateTime.Parse(txtDate.Text, Globalization.CultureInfo.CreateSpecificCulture("en-GB"))
The result for the above is:
From File: 13122011
Substring: 13/12/2011
Convert: 12/13/2011 - Crashes here
It seems like I keep having problems with dates. I am using the following code:
Dim LocalDateCultureProvider As New CultureInfo(CultureInfo.CurrentCulture.ToString) Dim CurrentDate As DateTime = Convert.ToDateTime(System.DateTime.Now.ToString("dd/MM/yyyy"), System.Globalization.CultureInfo.InvariantCulture) ExpiryDate = DateTime.ParseExact(strDate, "dd/MM/yyyy", LocalDateCultureProvider) If DateTime.Compare(ExpiryDate, CurrentDate) < 0 Then MsgBox("This file has expired.")
I'm using date in the format dd-mm-yyyy and I need to convert a string inthis format to a date type.My string is "18-01-2010" but when I do the conversion using dim TargetDate as date=CDate(TgDstr).where TgDstr is "18-01-2010", the resutant TargetDate, as note in the debugger window, is #1/18/2010# rather than #18/1/2010# which I expected.What change in code should I made to get the desired result?
(P.s. I've checked the current culture with the following line of code:
Dim str As String = CultureInfo.CurrentCulture.Name and get the result 'zh-HK'... and the date-time format I find in the control panel is also in dd-mm-yy format)
The user will select an entry in a gridview, which then redirects them to a form that is populated with the data from the selected row (thus making the gridview editable in a more user friendly way). Null values are accepted by the DB and I would like to show null date values as blank (or " ") in the corresponding text boxes. Instead I get the error:
Conversion from type 'DBNull' to type 'Date' is not valid.
Here is my code:
'preceded by connection code Dim sqlcmd As String = "SELECT * from Master WHERE RecNum = @recnum" 'Dim sqlCmd As New OleDb.OleDbCommand("SELECT * from Master WHERE RecNum = @recnum", connection) Dim FileCommand3 As New OleDb.OleDbCommand(sqlcmd, connection)
I use following codes to to convert string to date. In messagebox it displays correct date with format but in textbox it displays only #12:00:00 AM #. How to send date to textbox1 from variable mydate.
Dim mydate As Date Dim dateString = "31/12/2009" Dim formats As String() = {"dd/MM/yyyy", "dd/MM/yyyy"} Dim dateObject As DateTime = DateTime.ParseExact(dateString, formats, System.Globalization.CultureInfo.InvariantCulture, Globalization.DateTimeStyles.NoCurrentDateDefault) MessageBox.Show(dateObject.ToString("dd/MM/yyyy")) Me.TextBox1.Text = mydate
I'm trying to do some validation testing in VB.NET. If Entity.WeekEndDate.ToString = String.Empty Then ErrorList.Add(New cValidationError("id", "Incorrect Week End Date"))
Where WeekEndDate is of type Date. When I originally build the object, how can I insert a value into WeekEndDate that will generate an empty string(ie. "") when converted from a Date to a String?
I am pulling two fields and putting them together with a "-". When I export to excel it seems to think that the string is a date and converts it from 11-11 to 11-Nov. I can't seem to figure out how to fix this.I am exporting a gridview into excel. This asp.net using .net 3.5 and vb.net within VS 2008.

when running my program I get the following error:Conversion failed when converting date and/or time from character string. After playing a round with breakpoints I discovered the error to appear during:
When using INSERT INTO statement to SQL 2008 R2 to a column with data type as date and the data I am taking from a DateTimePicker control with date format as short. When my system date format short set to dd/MMM/yyyy the INSERT INTO statement is working perfectly but when the system date format short set to dd/MM/yyyy I am getting the above error.I tried by changing the control format to custom and dd/MMM/yyyy but still the same error is coming.I am using VB2010 and SQLExpress 2008 R2 SP1?
here is an sql query statement i run in vb.net. i keep getting the error of "Conversion failed when converting date and/or time from character string." whenever i try to execute this. the datatype of filing_date and approvale_date is "text" but the deyt variable is originally Date, converted to string: (Date.Today).ToString, like so. nulll is simply a variable with vbNullChar as its value.
Dim a As String a = "INSERT INTO tblVisitor(Name, Sex, TimeIn, EnterDate) VALUES('"& txtName.Text &"', '"& cboSex.Text &"', '"& Now() &"', '"& DateTime.Parse(cboEnterDate.Text) &"')"
[code]....
Which cboEnterDate is my DateTime Picker. Then I got the message:Conversion failed when converting date time from character string.
The error is: Conversion failed when converting date and/or time from character string.Basically I'm trying to make it so that when someone clicks a location in a list box it increments the correct field in a Stats table by 1 to say that they clicked the location. I've been trying to solve this for a while now and can't get anywhere. My date is in date format, and so is the Date field in my Stats table. My code can be seen below.
Dim Current As String Dim Check As String Dim objCmd2 As Object

The issue comes in with the second SQL statement I think. I don't understand why adding a date into a date field would be an issue, I've tried adding it as a string which didn't work.
Dim i as integer For i = 0 to 365 sqlinsert.InsertCommand="insert into cashdate (date) values (getdate()+'" & i & "')"[code]....
getdate is a function in the database that returns the datetime of now i have an error that says conversion failed when converting date or time from character string .what to do now ??
So basically, I have this RSS feed in hand. I converted the RSS into XmlDocument by the following:
Public Function GroveHallFromRss() As String Dim webClient As System.Net.WebClient = New System.Net.WebClient() Dim ourUrl As String = "http://abc.123.org/RSSSyndicator.aspx?type=N&
[Code]....
So I'm wondering how could I display the converted RSS as any other XML file with the nodes styled. (but not rendered and displayed by browser as RSS, but only styled XML)
I have a Generic.List(Of ImportedVehicle) - ImportedVehicle being a simple class as below.There is an enum property which is marked as public.When I serialize to XML using an XMLSerializer, the enum's value is just set to it's default value (which is NotAllocated) and doesn't actually represent the value that is set in code.[code]
I have a problem. I'm making a alarm clock and I need a way of converting a "dd/MM/yyyy HH:mm:ss" format into a date time format. This means I'll be able to compare the dates in a listbox using the for each function, to the current date and see whever it has passed and therfore the alarm should be deleted. It is currently in a string form so I can't use < and > to compare it to the current date as that is in a date form. I've tried using CDate but it doesn't work as it only will convert these formats:
This should be really simple and I figured out how to do it in VBA but it's different in .NET. I have a 3 digit Julian date that I would like converted to a regular date (Gregorian). So if the number is 91, then that means April 1st (non-leap year) and if it's 304 then that means October 31st (also non-leap year). In VBA I was using the Day and Month functions to help me get an output to make it mm/dd format.
My DataGridView is not sorting my date column correclty and it doesn't seem to be sorting it by String either. The column is bound to a date property, all is done using the designer.The set which I'm viewing it on is 424 entries long, there should be two entries for each date and they should be next to each other (regardless if sorting by date or string)The last few dozen entries are sorted correctly but the initial entries are not.Initially every second entry at the start is correct. Here is an extract if some of the sorting it does.(The beginning of the sorted grid is on the left, and the end of grid is on the right)
I'm trying to get an If statement to check is the date picked from a datetimepicker is at least 3 days prior to the current date, I can get it to calculate the difference however if I chose a date that 4 days prior to the current date (i.e the result being -4), the else statement doesnt fire.is this something to do with the result being a negative value? I did try to assign the DateDiff result to a variable defined as a short and then used this variable in the If statement, but still get the same issue. Option Strict isn't showing any issues.
First off a great piece of code [URL] you saved me soooo much time. I am a somewhat newbee to VB2010 and was wondering how would i go about setting lets say setting column(4) to a date format so that i can get it to sort in the correct order.
