I'm using ASP.NET/VB and I'm trying to insert a date and time into an Access date/time field, but I'm getting an error (Data type mismatch in criteria expression). Here's a simplified version of my code:
Dim myDate As Date = Now() Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (date_submitted) VALUES (?)", myConn) myIns1.Parameters.AddWithValue("@myDate", myDate) myIns1.ExecuteNonQuery()
Not sure why I'm getting the error, and not quite sure if this is even the correct way to approach inserting the current date. From looking at other similar questions it appears there are a few different ways to do this, but my technical knowledge is kind of limited so I'm having a hard time figuring it out (in other words deciphering the answers that use technical terms I know nothing about).
I am trying to insert date and time in dtime column in oracle database by using this code but it gives me following error ORA-01830 date formate pictures ends before converting entire output.
Using VB2010, I am trying to insert a row into an Access 2010 database. The database has several tables, but right now, I'm just trying to insert a row into a standalone table in the database.
My Task Background :I have list of data items and have to calculate/aggregate details about each data item and populate that to SQLServer database.I can do 1 by 1 insert [Traditional method]But, the application needs to perform good.Is it possible to aggregate the data in a 2d array and dump into database @ once ?' Populate this and insert it to database.
Private data(100, 100) As Object
So, how to do that ?Also, is it possible to use dataset in some way ?
If I declare my object at the beggining of my page class, and instantiate it in a dropdownlist selected_index change event. Shouldn't this object be available thru out the entire page and also persist thru a postback? I lose the object in my selected date change event in my calendar.
I'm trying to set the format of a column in a datagridview.When I put the format statement in the on load event for the form, it has no effect. When I put it in the cellformatting event I get the "Object reference not set to an instance of an object" error. I checked the column name. What I am doing wrong?
This is the code:Private Sub MeetingTblDataGridView_CellFormatting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellFormattingEventArgs) Handles MeetingTblDataGridView.CellFormatting Me.MeetingTblDataGridView.Columns("Starttime").DefaultCellStyle.Format = "HH:mm:ss" End Sub What I'm trying to do is get rid of the date part of a Date/Time field (stored in an Access database) in a datagridview column.
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)

I have a SQL database names TestSQLVB
In it a table called tblTest2, with a three fieldstest2id , int, pk, increment by 1field1, varchar(50)field2, varchar(50)
I have a dataset named Dataset2.xsd
A tableadapter named tblTest2TableAdapter
A insert query names InsertTest2 with fields @f1, @f2 and ExecuteMode = Scalar
When I run the following code per MSDN [URL] the database does not get updated.

im in the middle of doing sql queries i can search my data base usingGetDateFrom (Select, from, where) Me.nameTableAdapter.FillBy(namenDataSet.descip, Me.box1TextBox.Text,Me.box1TextBox.Text, Me.box2TextBox.Text, Me.box2TextBox.Text)i have this working fine im struggling with inderting data to my databse i have made the query ..
my sql statement is returning null when when I compare date from access database and date entered in textbox in vb. seems to me that the two dates are of different format so null is returned from the select statement but how do I go about this.[code]
After reading all the examples for list of T exists and Find and find first, none show how to handle multi-property objects. Below is bare bones example maybe someone could flesh out to show how this should be done.
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim DatePriceList As New List(Of DateAndPrice) DatePriceList.Add(New DateAndPrice(Date.Parse("1/1/2000"), 10.12)) DatePriceList.Add(New DateAndPrice(Date.Parse("1/2/2000"), 11.12))
I have a web app with a form that I am trying to pass to an ASP.NET server (using VB.NET) and then on to a MS SQL Server table. The form uses a jQuery datepicker in several textboxes and formats them as MM/dd/yyyy. The form fields are then passed through a PageMethod to the web server which takes the various field values and combines them into a SQL UPDATE command.
I am constantly getting the following error whenever I try to execute the SQL command:Conversion failed when converting date and/or time from character string.Here is the code on the server:
Using myConn As New System.Data.SqlClient.SqlConnection(CString.ConnectionString) myConn.Open() Dim cmd As New System.Data.SqlClient.SqlCommand("UPDATE table " & _
[code]....
Note: I've tried about twenty different ways of parsing the dates, converting them to dates, changing around the formats and none of it has worked.
Note 2: The conditional statements at the end are simply to prevent empty date fields from being stored in the SQL DB as "1/1/1900", but rather as an actual SQL NULL value. From debugging though, it seems that this is not the issue - it is when there is an actual value that the error is fired.
I have been disturbed for a week now. I have a project in vb.net. And on forms I have two masked text boxes. One is for the user to enter their date of birth and in the second one Iam trying to get the date the record is created. With this one I get the current date from pc and format it to dd/mm/yyyy because I want the user to understand the date. How do I INSERT the user date of birth and the the Now () date which is also in masked text box into a MYSQL database? I know how to insert other text but the date fails to appear in database.
I have some date fields that I want to not have any dates during a record creation. I figured the way to go would be to insert NULL. The way I'm going about it now gives me a Type mismatch error.[code]...
I am using VB 2008 and have a datetime picker. I wam trying to use this value in an INSERT command to load in to a table but I just can't get it to work. I debug it out which shows something along the lines of "24/03/2010" but it just won't accept it. However, if I create a string variable e.g. strDate = "24/03/2010". it works. I am obviously doing something wrong in the conversion.
