View 3 RepliesDatabase - Exception Occurs When Trying To View DataGridView
Nov 7, 2011I have a very simple table in access. The data is stored from VB.NET using the OLEDB adapter. I have a second form which has just a single DataGridView which was dragged/dropped using VS2010 from the Data Sources window.When trying to view the window the first time no data is shown and the second time an exception occurs and the program closes.
[code]...
In the Immediate window after clicking the Form.ShowDialog() button this message appears: A first chance exception of type 'System.ArgumentException' occurred in System.Data.dll Also, the data does not load into the datagridview. After closing the window and then clicking the same button (Not data has been changed at all) this error appears: Input string was not in a correct format.Couldn't store <07/11/2011 00:55:06> in Time Column. Expected type is Int32.
Database - How To Deal With Inserting Values Into Two Tables When Exception Occurs
Jul 21, 2010I have 2 tables loginInfo and UserInfo. LoginInfo Stores username and passwords while userinfo stores other user details such as Address,postalcode,phone etc.
I insert values into loginInfo first and if successful I enter the userInfo details. If exception occurs while entering details into userInfo i delete the loginInfo details.
This is how I do now
'login details are entered successfully
If CreateLogin(uName.uPass) Then
Try
'Create the user details
[Code]...
Is there a better way to deal with this situation? can use Transactions?

Getting Error: "Cannot Open Database "MainDB" Requested By The Login. The Login Failed. Login Failed For User 'D630Admin'."
Mar 15, 2012I created a SQL DB named MainDB.mdf and a small VB 2010 application with some forms and datasets.Everything was working OK until i got a new computer and re-installed Visual Studio 2010 and SQL server 2010 on it. I copied my DB from the old to the new computer and also copied by VB 2010 project to it. I used Windows Authentication to connect to the DB in the old computer and also in the new one, i am using different Windows user account names though.
I was able to connect to the DB in the new computer in the Server Explorer section, i created a new connection string to the DB and i can seed there is data in the tables. When i run my VB 2010 application created in the old computer get error:
"Cannot open database "MainDB" requested by the login. The login failed. Login failed for user 'D630Admin'."
I need to get rid of that error and be able to add/mod/del data from my DB using my VB application as i used to.
MySql Login - Lines Above To Login By Database - Error: "Incorrect Fields"
Jul 26, 2010I have the lines above to login by database. However, I really don't know why always give me the error: "Incorrect fields". I am 120% sure that all the fields of the table are right, including the text that I put into my textboxs. I have already add a user into the database. I can make login in PHP but in VB.NET I just can't.
Try
Dim MySQLConnection As New MySqlConnection("server=localhost; user id=root; password=; database=DB")
Dim MySQLQuery As String = "SELECT * FROM TableLogin WHERE Username = @username AND Password = @password"
[CODE]...
I already tried to show the data of the database into a Datagridview and it works fine, it displays to me all the rows that I had add in the database.
SQL - Cannot Open Database "mydb" Requested By The Login. The Login Failed
Feb 21, 2010I followed below attached tutorial but I got this error: Cannot open database "mydb" requested by the login. The login failed. Login failed for user 'NAME OF COMPUTER FOR THE NETWORKUsername'. Second question: When I deploy my application which communicates with SQL server, should I put in the installation file SQL server? If I need to deploy and SQL server, I have to configure server, right? P.S.I use SQL 2005. I changed Authentication Mode of the SQL server to: SQL Server and Windows Authentication mode.
