Sql Server - SQLException Obtaining More Information?
Jun 14, 2012
Currently working with converting SQLException error messages into messages that are more useful for the end user. My largest issue has been finding the information I'm looking for.For instance, error code 8114 is
"Error converting data type [Type1] to [Type2]" And error code 8152 is "String or binary data would be truncated"
Using ADO.NET in VB.NET with SQLServer, is there a simple way to figure out which columns are affected by these errors?
I am developing an application to be deployed on an XP Tablet edition PC. I am interested in monitoring information (e.g. Channel, AP MAC Address) about the Access Points that I am connecting to to location where in the facility a given Tablet PC is operating in.I have been unsuccessful in finding any code samples/snippets showing information on how to retrieve this sort of information.
i keep on getting SqlException was unhandled incorrect syntax near '+'.i cant seen to see whats wrong with my code.i hope someone can help me solve this code.[code]
I'm currently trying to create a function to parse error messages to make them more helpful for the end user. Currently I'm working with SQLServer and VB.NET.
Right now I'm raising error 547 which looks like this:
DELETE statement conflicted with COLUMN REFERENCE constraint Constraint Name. The conflict occurred in database 'Database Name', table 'Table Name',
[Code].....
I'm able to pull every piece of information I need from the error message except the name of the parentTable. I've already determined that the SqlException doesn't store the statement that caused the exception, and as far as I can tell it doesn't store information about the name of the parent table, only the table that is trying to reference it.
Is there an easy way to get the name of the parentTable?
My application requires a user to log in and allows them to edit a list of things. However, it seems that if the same user always logs in and out and edits the list, this user will run into a "System.Data.SqlClient.SqlException: Timeout expired." error. I've read a comment about it possibly caused by uncommitted transactions. And I do have one going in the application.
I have created a database holding general information about Patients using sql server management studio 2005. I then created an interface for the table created in visual studio 2008. I created a connection between sql server and the form using visual basic as language. I have a button to save the patient information. The problem is that the information entered is not saved in the sql server. [Code]
I am new to web services in VB.net. I have imported the WSDL into the Visual Studio 2010, but using the .net 2.0 "Web References" framework instead of the new "Service References".I simply need to learn how to pass my API key and one other piece of information through the API to the server. This is all that I have. What code to I need to add to a) Send the API Keyb) Send the Database Mode String
Public Sub Call_Web_Service_Method() Dim CallWebService As New PersonService.Header() Dim sPostAPIKEY As String = CallWebService.APIKey()
Created an XSD file that represents my table structure from my database. Created a class file to hold my functions such as the one below.
Code sample:
Public Function GetUser(ByVal UserID As String) As xsdUser.UserDataTable Dim SqlConn As New SqlConnection(ConfigurationManager.ConnectionStrings("MyDatabase").ConnectionString)
[Code]....
Now it seems odd to me to have two files doing what should be contained within just one file. I feel like I should have one class file called "User" and have member variables in there along with the class functions like the one above. But all the tutorials I see are using these data tables. On top of that I'm not sure how to handle the if statement at the end of the function. I don't think I would want to return a whole DataTable since I should only have one row, and I also don't know how I would handle an error if my function is supposed to return a data table. I suppose I could return an empty one and then if the table is empty in my code then I would handle it there, but this also seems messy.
Is this the common way of retrieving information from a stored procedure? Or is there a more up-to-date method that I'm not seeing in my search results?
I am real new in vb. I need to connect to ms server and retrieve information for database. Just simple ''select * from update, delete and so on.If I add new data source using data source configuration wizard - everything is fine, but I want to use just simple selects.I use
Dim connectionString As String = _ Provider=Microsoft.Jet.OLEDB.4.0;Data Source=BBD-2;Initial Catalog=wilopumpen1;Persist Security Info=True;User ID=*****;Password=****;" Dim queryString As String = _ "SELECT * from dbo.tableName "
I'm developing a Windows application that runs on a terminal server and users connect to it via remote desktop. Standard stuff. However, I would like to know something about the user and I was wondering if there's a way to get some information about the client that the user connects from (his local machine).
I have built a very simple application which has buttons, and dropdowns containing links to intranet/internet sites.As I have no Idea on how to put them into a database for easy maintenance, this app will no doubt cause me pain.Nevertheless.. When I do create a new revised version of the file.. eg 1.0.0.1 how to I go about setting the application to auto check for updates ?
I've been scrambling my brain to figure out how to access my FTP server thing to get a list of text files in a folder and to edit the contents of those files online.
I'm currently working on a legacy project in VB.NET 2.0.The project has a very funny DAL-layer which does not incorporate transactions :-|Anyway, it's my job to make some parts of the program transactional and I don'thave access to the DAL layer code.So I'm trying to put entire sections of code inside single TransactionScope.
I am connecting to a vendor-supplied Web Service running in our domain and am attempting to execute one of its methods. I am receiving the error below (Timeout Expired) and not sure how to fix it. The server is running SQL Server 2000 (soon to be upgraded!) and I have checked the timeout setting which is set to 0 (unlimited)
I just got this error while creating my own login form. It generates an error "Invalid Column name manoyanx" where 'manoyanx' is the string i am querying in the database. Here is my snippet :
Dim connetionString As String Dim cnn As SqlConnection Dim mycomm As SqlCommand = New SqlCommand Dim dr As SqlClient.SqlDataReader
[code].....
the highlighted line of the code is dr = mycomm.ExecuteReader
I'm trying to store a data from the checkbox. when i checked on NSO Birth Certificate it has to be stored into my mssql server.here is my code
If nso.Checked = True Then strsql = "insert into student info(Requirements) values ('" & nso.Checked & "')" Dim sqlcmd As New SqlClient.SqlCommand 'opens the db
This may or may not need to be moved to the deployment folder...Okay I have a vb.Net application that connections to a sql server 2005 database "TacticalDB" while debugging the application I was using the connection string,
Dim con As SqlConnection = New SqlConnection("Data Source=.SQLEXPRESS; AttachDbFilename=" + Application.StartupPath + "DataTacticalDB.mdf; Database=TacticalDB; Trusted_Connection=True; User Instance=true")
Which works fine, but I have moved into getting the application ready for deployment and so I created a setup application in the same solution as the application. Now I have added the database file with the setup but when my application gets to the con.Open() line it catches an exception,
System.Data.SqlClient.SqlException: Database 'C:UsersJohnDocumentsVisual Studio 2008ProjectsBlackout_ScoutBlackout_Scoutinx86DebugDataTacticalDB.mdf' already exists. Choose a different database name. Cannot attach the file 'C:Program Files (x86)MicrosoftSetup1DataTacticalDB.mdf' as database 'TacticalDB'.
[code]....
Now I only have the one place where the application should look for the Database and thats Application.startupPath/Data/TacticalDB.mdf and if im running the newly installed exe it shouldn't look back in the myprojects folder but it is.
I have a aspx page with several input fields(couple of int's and strings) and 3rd party gridview. Data is validated, and stored procedure is called from code behind to save data in DB. Gridview has capability to display error box to user which can be called from code behind. So when I catch exception I give it my error message(error message is something like:"Data can't be saved to database. Error:" & ex.message and call function that displays errorbox.
What I am trying to do is have a button that will pop up a dialog to where you can select a directory. Then the path of the directory will be placed in a text field.Click Button > Dialog Pops Up > Select Directory > DirectoryField.Text will equal "C:Program FilesStuff"
How do you provide an image to the program, so the program finds that image on the screen and tells its coordinates. So if I was to provide an image of the start button, the program would tell the coordinates like (2,1000) or something similar.
