I starting getting the error above today when attempting to deploy updated DSV's and Report models. I can't seem to locate any info about this error - seems like a generic one. We're on 2005 SP1 (think we're on build 2221). Any help is appreciated!
View 5 RepliesGreetings everyone, I am attempting to build my first application using Microsofts Sql databases. It is a Windows Mobile application so I am using Sql Server Compact 3.5 with Visual Studio 2008 Beta 2. When I try and insert a new row into one of my tables, the app throws the error message shown in the title of this topic.
'((System.Exception)($exception)).Message' threw an exception of type 'System.NotSupportedException'
My table has 4 columns (i have since changed my FavoriteAccount datatype from bit to Integer)
http://i85.photobucket.com/albums/k71/Scionwest/table.jpg
Account type will either be "Checking" or "Savings" when a new row is added, the user will select what they want from a combo box.
Next is a snap shot of my startup form.
http://i85.photobucket.com/albums/k71/Scionwest/form.jpg
Where it says "Favorite Account: None" in the top panel, I am using a link label. When a user clicks "None" it will go to a account creation wizard, and set the first account as it's primary/favorite. As more accounts are added the user can select which will be his/her primary/favorite. For now I am just creating a sample account when the label is clicked in an attempt to get something working. Below is the code used.
private void lnkFavoriteAccount_Click(object sender, EventArgs e)
{
FinancesDataSet.BankAccountRow account = this.financesDataSet.BankAccount.NewBankAccountRow();
account.Name = "MyBank Checking Account";
account.AccountType = "Checking";
account.Balance = Convert.ToDecimal("15.03");
account.FavoriteAccount = 1;//datatype is an integer, I have changed it since I took the screenshot.
financesDataSet.BankAccount.Rows.Add(account);
//The next three lines where added while I was trying to get this to work.
//I don't know if I really need them or not, I receive the error regardless if these are here or not.
this.bankAccountTableAdapter1.Update(financesDataSet);
this.financesDataSet.AcceptChanges();
refreshDatabase();
}
the refreshDatabase() code is here:
private void refreshDatabase()
{
this.bankAccountTableAdapter1.Fill(this.financesDataSet.BankAccount);
//Aquire a count of accounts the user has
int numAccounts = financesDataSet.BankAccount.Count;
//Loop through each account and see which one is the primary.
for (int num = 0; num != numAccounts; num++)
{
//Works ok in frmMain_Load, but when my lnkFavoriteAccount_click calls this, it throws the error.
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
{
//Display the primary account on our home page. User can click the link label & be taken to their account register.
this.lnkFavoriteAccount.Text = this.financesDataSet.BankAccount[num].Name.ToString();
this.lnkFavoriteFunds.Text = this.financesDataSet.BankAccount[num].Balance.ToString();
break;
}
}
}
and my form_load code
private void frmMain_Load(object sender, EventArgs e)
{
refreshDatabase();
}
So, when I click on the lnkFavoriteAccount label, and my new row gets added, the app stops at the following line in my DataSet.Designer
[global:ystem.Diagnostics.DebuggerNonUserCodeAttribute()]
public byte FavoriteAccount {
get {
try {
return ((byte)(this[this.tableBankAccount.FavoriteAccountColumn]));
}
catch (global:ystem.InvalidCastException e) {
//Stops at the following line, this error was caused by 'if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)'
throw new global:ystem.Data.StrongTypingException("The value for column 'FavoriteAccount' in table 'BankAccount' is DBNull.", e);
}
}
set {
this[this.tableBankAccount.FavoriteAccountColumn] = value;
}
}
I have no idea what I am doing wrong, all of the code I used I retreived from Microsofts help documentation included with VS2008. I have tried used my TableAdapter.Insert() method and it still failed when it got to
if (this.financesDataSet.BankAccount[num].FavoriteAccount == 1)
in my refreshDatabase() method it still failed.
When I look, the data has been added into the database, it's just when I try to retreive it now, it bails on me. Am I retreiving the information wrong?
Thanks for any help you guys can offer.

Hi,
I got an strange problem with one of my packages.
When running the package in VisualStudio it runs properly, but if I let this package run as part of an SQL-Server Agent job, I got the message "The script threw an exception: Exception of type 'System.OutOfMemoryException' was thrown." on my log and the package ends up with an error.
Both times it is exactly the same package on the same server, so I don't know how the debug or even if there is anything I need to debug?
Regards,
Jan
All,
I have a large package (I know the recommendation is to have one package per data flow.) It has 20+ data flows in it. Personally I have found it much too complex to manage dozens of packages just because I want to have more than one data flow in my package.
I have been working on this package in an iterative manner over the past several months. Recently, I noticed I started getting the error message: "Exception of type 'System.OutOfMemoryException' was thrown" when I went to save my package. This is _extremely_ frustrating, because when this happens, all the changes I have made are generally lost. Occasionally, I have noticed if I close some other BIDS windows, or just wait a bit, I will be able to click save again, and it will actually save. Usually, I am forced to just "end-task" Visual Studio.
Other than splitting the package up into 20 separate packages, is there a way around this problem? I would rather put up with the lost changes than switch to dealing with 20 separate packages. It just makes things to difficult to manage when everything is split up into so many packages - particularly when I am passing variables around from parent to child packages.
Please help!
Thanks,
David Baldauff
Hi,
I've written this code multiple times now. But for the first time i get an error at the line underlined. My procedure runs perfectly when i execute it through Sql Query analyzer.
plzz help.. Its urgent and am unable to find the reason for this error "A first chance exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll"
Thanks !SqlConnection conn = new SqlConnection(DbConnectionString);
conn.Open();
SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "dbo.rqryTradesPRR";
cmd.Parameters.Add("@COBDate",SqlDbType.DateTime).Value = "2002-10-31 00:00:00.000" ;
SqlDataReader reader = cmd.ExecuteReader();
while(reader.Read())
{
// have written something here
}
Thanks in advance !
My SqlConnection is causing an error "sqlConn.ServerVersion threw an exception of type System.InvalidOperationException". Everything I have read seems to suggest that there is a problem with my SQLConnection parameters but as you can see from the commeted code below I have tried three different servers with four different configurations. I am out of ideas on what is causing the error.
Thanks - Amy
Here is a section of my code:
String sqlStmt = "Select [UserName], [Password], [Last], [First] from Contacts Where Login=@Uid AND Password=@Pwd";
SqlConnection sqlConn = new SqlConnection("Data Source=localhost;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=pe2800;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=HorizonDC02;Initial Catalog=test;Integrated Security=SSPI;");//SqlConnection sqlConn = new SqlConnection("Data Source=HorizonDC02;Initial Catalog=test;User ID=username;Password=password;");
SqlCommand sqlCmd = new SqlCommand(sqlStmt, sqlConn);sqlCmd.Parameters.Add("@Uid", SqlDbType.VarChar, 30).Value = uid;sqlCmd.Parameters.Add("@Pwd", SqlDbType.VarChar, 30).Value = pwd;sqlCmd.Connection.Open();
Getting this error "Exception Has been thrown by the target of an invocation" when trying to create Integration Services Project. Any ideas what can be wrong?
Thanks.
I have this exception on page loading, is there any solution for this how can I fix this exception...
View 2 Replies View RelatedHi,I'm developing a desktop C# app that uses SQL Everywhere as an embedded database. I generated strongly typed DataSet and use that to populate a DataGrid on my app.When the app first loads, it populates the DataGrid with a line like this:
this.sTORE_INV_LNTableAdapter.Fill(this.inventoriesDataSet.STORE_INV_LN);
That all works fine. Later on, after adding more data to the database (through reading a csv file), I wanted to refresh the display on the DataGrid.
I used the same line of code:
this.sTORE_INV_LNTableAdapter.Fill(this.inventoriesDataSet.STORE_INV_LN);
however, this time, the following exception was thrown:
The database file cannot be found. Check the path to the database. [ File name = .\Inventories.sdf ]
Does anyone know what may be going on? I saw this article about a bug in VS 2005 when using strongly typed DataSets (http://channel9.msdn.com/wiki/default.aspx/MobileDeveloper.DatabaseCannotBeFoundErrorInTypedDataset)
but that doesn't seem to apply here.
The connection string is identical both times that line of code is called so I'm a bit baffled with what's going on.
Any help would be appreciated. Thanks,

Hi,
I replace the reference assembly System.Data.SqlServerCe with version 3.5 beta2 in Microsoft.Practices.EnterpriseLibrary.Data.SqlCe. When I used the Data.SqlCe block in application, an exception ("Cannot access a disposed object named SqlCeConnection") threw. This didn't occur in SSCE 3.5 beta1 and early versions.
Finally I found the difference between beta1 and beta2.
In the SqlCeConnection class, there is a RemoveWeakReference method. this is code snippet of beta1:
internal void RemoveWeakReference(object value)
{
if (this.weakReferenceCache != null)
{
this.weakReferenceCache.Remove(value);
}
}
and this is for beta2:
internal void RemoveWeakReference(object value)
{
if (this.weakReferenceCache == null)
{
throw new ObjectDisposedException("SqlCeConnection");
}
this.weakReferenceCache.Remove(value);
}
So, if we dispose a connection before a command, such as:
SqlCeConnection cn;SqlCeCommand cmd;... cn.Dispose();cmd.Dispose(); // Error, an exception will be threw. Is it a bug of Beta2?
Running 2005 Beta 3 Refresh. When I first deploy, it works fine. Subsequent deployments yield the following error:

I have been encountering a problem using a CLR Assembly in SQL server. The Assembly is one provided by Microsoft for an example on using Exchange web services with SQL server.
http://www.microsoft.com/downloads/details.aspx?FamilyId=D6924897-7B62-46FD-874E-24FB0FBA2159&displaylang=en#Requirements
Essentially what this package is, is a set of c# classes that access the Exchange 2007 Web Services via a set of user defined functions and views in MS SQL Server 2005.
We have not modified the code except to configure for our host environment.
We are able to register the assembly using the setup.sql file included. But when we try to access any of the views or use the functions we get the following error:
Msg 10314, Level 16, State 11, Line 10
An error occurred in the Microsoft .NET Framework while trying to load assembly id 65551. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error:
System.IO.FileLoadException: Could not load file or assembly 'exchangeudfs, Version=0.0.0.0, Culture=neutral, PublicKeyToken=777b97dde00f3dbe' or one of its dependencies. The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

We have 3 testing environments. 2 Windows 2003 servers called test and test2. Also a single Windows 2000 server called test3. Test and test2 have a full suite installed on them, web server, exchange 2007, sql server 2005, they are also domain controllers for their own domains.
We get the above error on test and test2 but it runs fine on test3. Test and test2 represent what our production environment is like. Test3 was just part of our troubleshooting process.
We have tried a lot to make this work. Here are some details on the things we have tried.
The database is set up to allow CLR Assemblies. This is part of the setup.sql.
The assembly's permission is set to external_access.
We have gone all the way to setting the file permissions on the dll to full control to the Everyone group.
We have tried different accounts to run the SQL Service. We've tried the system account, the local admin account and a seperate user account.
The database we are using is a fresh brand new database. Therefore it does not fit into the bug reported in this article:
http://support.microsoft.com/kb/918040
I am really at a loss to where to go from here. Any ideas on why this 'out of the box' solution is causing us so many headaches would be appriciated.
Thanks,
Tim
I just opened a large table with about 800 columns and 300,000 rows.
Doing the right click open on table displays message: Exception has been thrown by the target of an invocation.
Please help me determin what the error is and how to solve it.
I have google it for days now and no one has similar situation as mine. Many have same error, but their fix is not relevant to my issue. If you know about some SQL query limit please let me know.
Funny thing is that if I right click table and do script ---> select, then it does pull the data. ONly doesn't work when I do "Open Table."
Thanks for your help.
I have a custom SSIS Script task (c# code) which , using WINSCP secure FTP libraries, downloads files from an FTP server to local folder.This works perfectly fine on my personal machine.But when I deploy the project on to Catalog, and try and run the same SSIS package using Agent Service , I get this error -Â "Exception has been thrown by the target of an invocation."
The Service account used to run the package (on the server) has all the needed permissions to write into the folder on the server.
've got an execute task that take data from a simple table ,I set up the variable Passing as object and I pass the variable to a For Each loop container..
I call the variable in the for each loop container and using the script VB I try to msgbox the variable but it gives me the error:
exception has been thrown by the target of an invocation.
What's wrong?
Help,
I get the following exception anytime I attempt to open a .dtsx file in the SSIS project in VS2005:
"External component has thrown an exception. (System.Windows.Forms)"
I haven't made any changes to this project and it was up and running fine a week or so ago. Any ideas? Help.

Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

//System.Data.Odbc.OdbcDataAdapter oLead = new System.Data.Odbc.OdbcDataAdapter();
//SqlDataAdapter oLead = new SqlDataAdapter();
System.Data.DataTable dt = new System.Data.DataTable();
DataSet ds = (DataSet)this.Variables.ObjVariable; // here i am getting error
ds.Tables.Add(dt);
ADODB.Record rs = new ADODB.Record();
oLead.Fill(ds, rs, "Variables");
foreach (DataRow row in dt.Rows)

Output0Buffer.Column = (int)row["Column"];
Output0Buffer.Column1 = row["Column1"].ToString();
Output0Buffer.Column2 = row["Column2"].ToString();
}
}
}

Hello,
I have created a report model project using BI studio, to try ad-hoc reporting. In that project, i have also created a report model for a database named Galactic that resides in my sql server instance. When i want to deploy the project to the report server it gives following error:
Error 1 The path of the item '//GDS/Models' is not valid. The full path must be less than 260 characters long; other restrictions apply. If the report server is in native mode, the path must start with slash. 0 0
Properties of my project are as follows:
OverriteDataSources : False
TargetDataSourceFolder : /GDS/Shared Reports
TargetModelFolder : /GDS/Models
TargetServerURL : http://localhost/ReportServer
By the way, i have a second problem. When i try to open the url "http://localhost/ReportServer" it asks for a user name and password. altough i provide my windows account's user name and password which have administrator rights, they are not accepted.
hi,
ive been using rsscripter to deploy my reports/models.
this has been working fine but i am now getting an error deploying one of my models:
Running script "XModels estDSV.smdl.rss"

If i deploy the model manually (from visual studio) the model is successfully deployed.
Anyone seen this error before?
Thanks.
Good Afternoon.
I am trying to write a short application within which I would like to embed a SQL Server Express database, all of which would be deployed via ClickOnce through a web site. The installation process seems to be working without trouble, including installation of the .NET Framework 2.0 and SQL Server Express 2005.
When the application launches on the new machine, however, I get a big Microsoft .NET Framework "Unhandled exception" error dialog box that indicates the database already exists and that the database file could not be attached. I am working with a clean virtual machine that I know has never had the database installed on it.
I fear I am overlooking something quite straightforward, but since this is the first time I have ever attempted to build a data-bound application, I am not sure where I am going wrong.
Perhaps the source of the problem, or a related problem, might be revealed even when I run the application in debug mode from within Visual Studio. I can run the application once, but if I try to run it again, I get an error when I try to open the database connection that is similar in content (database already exists...could not attach). I can run the SSEUtil and detach the database and then run the application again in debug mode and it works no problem (the first time!).
Lastly, if I install the application on the machine on which it was developed and make sure the database is detached, it will run without any trouble (even repeatedly). But, on a new blank machine, there is no database listed that matches my database name, so I cannot try to detach anything!?
My apologies for such a novice question!

In order to deploy the replication implementation along with the software that has been created,how to package the correct set of necessary assemblies along with our client to ensure that the software can function correctly?

Hi all,
I did make changes in to webconfig with time out = 1200 and maxrequestlength = '102400' ( i think it is 10 mb)
I also made changes to machine.config.comment requestLimit = "50147483647" [number] ( does it mean 5 MB or G)
My report model is 4 MB and it still keep getting error of
Error 2 There was an exception running the extensions specified in the config file. ---> Maximum request length exceeded. c:documents and settingspdesaimy documentsvisual studio 2005projectshrintegral_reportmodelHR Integral1.smdl 0 0
I have a VS 2012 SSIS project with more and more packages being added. I've got project parameters so I'm committed to the project deployment model (which is pretty convenient BTW). My question is how we're supposed to occasionally limit the packages we want deployed. There are times when 2 or more packages may be in development and 1 is deployable and the other not. I can temporarily exclude the not ready package and then deploy. It seems cumbersome bringing it back in. BIDS complains that all the tasks have lost their connection managers; even though they're are present in the editor. And it makes a copy of the .dtsx.
what's the recommended way to work in this environment?
