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.
View 4 RepliesI am trying to re write a VB6 program using MS Access, many years ago, using VB 2010 express and SQL server 2008 R2 Express. I have a database with several tables, which I created using the designer. I am able to connect to the database and select data and display it in textboxes etc in vb code. What I have not been able to in code is to INSERT rows DELETE rows or UPDATE any data in the tables. I can do any of these operations using the Query Designer, but I want to do it in code. I can post some code if necessiary, but I thought it might just be some property that I had not set in the designer.

Title pretty much says it all. How do I format the date of a dateandtimepicker to insert it into the SQL date datatype?

I tried to start using VB 2010 Express with a program I originally developed with VB 2005 Express that I moved to VB 2008 Express successfully a couple years ago. It uses a database file (*.mdf) that is on the computer ( not out on a server). When attempt to run the program in debug mode, I get the following error "An attempt to attach an auto-named database for file C:Documents and SettingsTomMy DocumentsQuizzing StuffQuestion Database 2010QuizQuest ionGameQuizQuestionGameinReleaseQuizQuestionDB.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share."
I first made a copy of the entire project folder that was working in VB 2008 Express and gave it a different name. In VB2010 I opened the project in the copied folder and it said it successfully converted the project. I am able to open the Data Source inthe Designer and see the database structure as I expect. I think the project is still using SQL Server 2005 Express (because it is what is checked in the list of prerequisites on the Publish tab).
Note, I have programmed off and on for many years, but fairly new to using databases and SQL Server.
Here is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.

I'm running Microsoft Visual Basic 2010 Express on Windows 7, using a Regional Setting set to New Zealand.
When I enter a date in a NZ format (d/mm/yyyy), the IDE highlights the date and tooltip reports date constant not valid. But it is valid for NZ! Meanwhile, the IDE happily accepts dates in the US format.
I would have expected VB to look at my PCs regional settings and set this as the default format. What is wrong here? I have reinstalled the application, but still have the same problem.
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 " & _

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 was wondering how can I fill a column automatically in the database with the GETDATE() ?

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.
