Problem Getting DTS Object To Work On A Web Form

Feb 26, 2007

Hi;

 I would like to run a DTS package from the On click button event on a web form.

I tried using code that works in a windows form.

But ASP.net, VS 2005 doesn't like the code.

Here are the libraries that I used with the windows form.

 Imports System, Imports System.Data. Imports System.Data.SqlClient.

Is there a library that I am missing ?

And here are the lines of code that won't compile:

 Dim oPackage As New DTS.Package2Class

Dim oStep As DTS.Step

Package.LoadFromSQLServer("123WXYZTRSQL", , , DTS.DTSSQLServerStorageFlags.DTSSQLStgFlag_UseTrustedConnection, , , , "cpyPrinters2Excel", )

I am able to run the above in a windows form with no problem.

Thanks for any insights,

Gordon

Inserting Data In SQL 2005 Using Javascript From A Form Object

Mar 4, 2008

I am new to ASP.NET. At present i am developing a web application in which i need to insert data in database(MS SQL 2005) from a form which uses only HTML controls. I need to use HTML controls so posting of form to the server is not done and hence i need to generate HTML controls using javascript. So the data in the form must be stored in the database. How this data can be inserted in the database is the problem and i think that javascript might be the solution for it.

Binding A DataSource Table Column To A Form Object (RadioButtons)

Oct 25, 2006

Hi,

  I have a little question.  I have an application which interfaces with a SQL Express Database.   On a form, I want to bind a control which is made of several Radio buttons to a table column which is in fact a varchar(1).  This is the picture:

        Table column:  OptVisualRpt  varchar(1)

        Screen control:  2 radio buttons

                                    rb_VisRPTbImp_O    for "yes"

                                    rb_VisRPTbImp_N    for "no"

 

  I'm really scratching my head as how I can bind a single table column to my radio buttons controls.   I think that I just can't this way but rather have to use an intermediate variable or control. 

Solution 1?

 I thought of using a local variable that I would set to "y" or "n" following "CheckedChanged" events fired from radio buttons but I don't know how to bind this variable to my table column.                 

Solution 2?

  I thought of placing a hidden text control into my form, which one would be binded to my table column, that I would also set to "y" or "n" following "CheckedChanged" events fired from radio buttons.

Any of these solutions which would be feasible or any more neat way to do it?

Many thanks in advance,

Stéphane

Where To Order The Table Values Displayed In A Web Form Object? In Sql Server Or In The Application?

Sep 10, 2004

Hi,

I have a table in my database with several car types, and the order I want for that table is:

Car_typeA_1
Car_typeA_2
Car_typeA_3
Car_typeA_4
Other_Cars_typeA
Car_typeB_1
Car_typeB_2
Car_typeB_3
Other_Cars_typeB
Car_typeC_1
Car_typeC_2
Car_typeC_3
Car_typeC_4
Car_typeC_5
Other_Cars_typeC
...


This table is more or less always the same, but from time to time I want to add a new car type, for instance; Car_typeA_5, but this new type must be located under the last register, in the example under ‘Other_Cars_typeC’. So, now the order is wrong, and when I want to display these car types to a web form object, the items will appear wrong ordered.

My question is: To order the values(items) correctly, Where I have to do it? In the web page (ASP.NET) code behind, or somewhere in SQL Server (for example in the Stored Procedure that passes the value to the application)? Or maybe in the same database table..?

Thank you,
Cesar

One Form To Update Different SQL Tables Based Upon Form Selection

Apr 16, 2008

Hello,
My company Intranet has a form that agents can use to post their comments about the company to upper management, but our customer service department would like to modify the form so that the agent has to pick from a comment type.
The dropdown options on the form will be as follows:
ComplimentsComplaintsGeneral CommentsSuggestions
Each dropdown option has a designated table in a SQL DB.Using postback on the same page, I need to change which fields of the form are visible based upon which dropdown selection the user chooses, and I need the fields to then be inserted into the table that corresponds with the dropdown selection item.
For example: If the Compliments dropdown selection is picked, I need a text box to show for the user's location, the name of the customer, account number, and the message box. Once the submit button is clicked, the characters in these boxes need to be inserted into the Compliments table using its data adapter.
However, if the user selects Suggestions, the name of the customer and the account number should not be visible, since these fields do not exist and when the submit button is pressed, the Suggestions table should be updated.
If you need more information, I will provide whatever is needed.
As always, thanks for everyone's assistance.
Chris

How To Make The SSMSE To Return Whole Records Without Any Close Query Form And Re-create Query Form Operation?

Dec 25, 2007

Hi,
I got a problem.
I installed Microsoft SQL Server Management Studio Express 2005 version.
And I created a Compact database.
I created an connection in SSMSE to connect the database and opened a query form.
then, i run the following sql:

Select * from Table1

It returned 3 records to me.
After that, I used program to insert record into this table.
Then i ran this sql again, it still show me 3 records.
I closed the query form, and re-created a new query form, then run the sql, it returned 4 records to me.

Why? It's very strange and difficult to operate, right?
Is there anyone know how to make the SSMSE to return whole records without any close query form and re-create query form operation?

Thanks a lot!

And Merry X'max!!!

First Form Normalizations And Second Form Normalization

Jul 19, 2006

Hi everyone,
What is the main difference between first form normalizations and second form normalization ?
In my opinion, they are both generated for the same operation which is to prevent redundancy(in other words; duplication of data in several records).
So would you please explain it to me ?

Thanks

' The Definition Of Object [object Name] Has Changed Since It Was Compiled' Error When Altering A Trigger In 2005

Aug 17, 2007

Hello All

Not sure if this is the right forum to post this question to, so if it's not, please accept my apologies.

I'm working in SQL Server 2005 with a database that was migrated to 2005 from SQL Server 2000. I have to alter a trigger on a table for some functionality changes, and when I modify the trigger and then access it through the application the database is working with, I receive this error:


There was a error in the [stored procedure name] procedure. Error Number: -2147217900 Error Description: [Microsoft][ODBC SQL Server Driver][SQL Server]The definition of object '[trigger name]' has changed since it was compiled.


[stored procedure name] and [trigger name] are where the actual names appear in the message.

I've tried running sp_recompile on the trigger, stored procedure, and table that are associated with this, and nothing works. I have dropped the trigger, which allows the save process to complete (but doesn't perform the required functionality, of course), and then re-created the trigger, but the error message still comes up. The compatibility level for the database is SQL Server 2000 (80) (as it was migrated from SQL Server 2000 as I mentioned above).

Has anyone seen this, and if so, how can I fix it?

Thanks in advance for your help!

When Using A Sqldataadapter In VS 2005 I Get The Following Error At Runtime. Object Reference Not Set To An Instance Of An Object

Dec 21, 2006

Help! I have posted this before and I had hoped that the VS2005 SP1 would help my problem. It didn't. My code is shown below. I have dropped a sqlconnection, sqldataadapter and a strongly-typed dataset from the toolbox onto the component designer for my page and written my code. It compiles without any errors but at runtine I receive the system error "Object reference not set to an instance of an object." The error occurs at the first line where the sqldataadapter is mentioned. I have shufflled the code and the error still occurs at first mention of the dataadapter. I have set parameters to a simple string such as "myemail." It hasn't helped.

Predict Query Gives 'DMPluginWrapper; Object Reference Not Set To An Instance Of An Object' Error

Mar 17, 2008



Hi,

I am trying to develop a custom algorithm. I have implemented and tested training methods, however I fail at prediction phase. When I try to run a prediction query against a model created with my algorithm I get:


Executing the query ...
Obtained object of type: Microsoft.AnalysisServices.AdomdClient.AdomdDataReader
COM error: COM error: DMPluginWrapper; Object reference not set to an instance of an object..
Execution complete


I know this is not very descriptive, but I have seen that algorith doesn't even executes my Predict(..) function (I can test this by logging to a text file)
So the problem is this, when I run prediction query DMPluginWrapper gives exception -I think- even before calling my custom method.

As I said it is not a very descriptive message but I hope I have hit a general issue.

Thanks...

When trying to create a new Integration Services Project and start work in the designer receive the MICROSOFT VISUAL STUDIO 'Object reference not set to an instance of an object.' dialog box with message "Creating project 'Integration Services project1'...project creation failed."

Previously I had SQLServer 2000 client with the little VS tool that came with it installed. Uninstalled these prior to installing the 2005 tools (VS and SQLServer).

I'm not finding any information on corrective action for this error.

Any one have this problem and found the solution?

Report Server Issue Object Reference Not Set To An Instance Of An Object

Nov 14, 2006

Hi all,

I'm getting this problem 'Object reference not set to an instance of an object.' whenever I try to review a report and I checked the log file and this is what it had

Reporting Services Error - Object Reference Not Set To An Instance Of An Object

Jan 14, 2008

Hello -

For the life of me I cannot figure out why i'm getting the "Object Refence Not Set To an Instance of An Object" error after I try and create a Report Services project in Business Intelligence Studio. I've followed all of the steps in similar posts such as checking the ReportServer/web.config file but everything checks out.

Does anyone have any other ideas as to how I can get rid of this annoying error and start creating some reports?

Thanks!!!

Script Component Throws Object Reference Not Set To An Instance Of An Object

Dec 27, 2007

Hello,

I've ran into trouble while creating a rather simple transformation script component (one input, one output). The only thing it has to do is test the values coming from it's input rows and set the values of the output rows according to some rules; something like:





Code Block

Public Overrides Sub InputBrowser_ProcessInputRow(ByVal Row As InputBrowserBuffer)


If Row.UserAgent.Contains("MSIE") Then 'test input
Row.BrowserName = "Internet Explorer" 'set output
End If



End Sub

This raises an "Object reference not set to an instance of an object." exception. Commenting out the input (Row.UserAgent) solves the exception, but I actually do need to test the contents of the input row (and by leaving only the output manipulation, the script won't reach it's end, the components remain yellow). What can I do about this?


Thanks in advance!

Object Reference Not Set To An Instance Of An Object. And Connection String

Feb 18, 2007

Hi, I am deploying my web through a web hosting services which provides SQL database support. I got following errors whenever I try to open my webpage,which never happen when I run my web on the local machine.  I have my connection string configured in my web.config as below:
<add name="ArtHouseConnection" connectionString="Server=serveripaddress; Integrated Security=True; Database=arteh3_database;User Id=username;Password=password;" providerName="System.Data.SqlClient"/>
<add name="ASPNETDBConnectionString1" connectionString="Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
This is the source code where error was generated:
public static class ArtHouseConfiguration
{
//cache connection string
private readonly static string dbConnectionString;
//cache data provider name
private readonly static string dbProviderName;
private readonly static string siteName;

static ArtHouseConfiguration()
{
dbConnectionString = ConfigurationManager.ConnectionStrings["ArtHouseConnection"].ConnectionString;
dbProviderName = ConfigurationManager.ConnectionStrings["ArtHouseConnection"].ProviderName;
siteName = ConfigurationManager.AppSettings["SiteName"];
}
and finally this is the error mg I got:

SQL 2012 :: Get Object Type For Synonym Base Object?

Jun 17, 2014

I need to get the object type (view, table ...etc) for a synonym base object inside a script. The only place where I see something related to this stored is in column "base_object_name" in sys.synonyms but there I can see only the same with format [database].[user/schema].[name]. After some testing playing with different users without specifying database/schema I think that maybe the object_id must be stored in a another place, my first idea was parent_object_id in sys.synonyms but it isn't stored there.

know if object_id for the base object is stored in any other place ?

Forms Authentication - Object Reference Not Set To An Instance Of An Object

Apr 12, 2007

I have successfully implemented forms authentication, that means, I can access it from a web browser, get the login page, add my credentials and log on to Reporting Services.



But now I try to access reporting services Web service from a winforms app, doing something like this:

ReportingService _rs = new ReportingService();

_rs.LogonUser("myUsername", "myPassword", "");

_rs.Url = "http://myServer/ReportServer/ReportService.asmx";

CatalogItem[] items = _rs.ListChildren("/", true);



The first three lines works fine, but he last line (ListChildren) throws a "Object reference not set to an instance of an object" exception. I have enabled remote error and looked in the RS log files, but nowhere I can find where this null-pointer exception occured.



Any idea about where to go from here?



Regards Andreas

Getting Object Reference Not Set To An Instance Of An Object In Execute SQL Task

Jun 6, 2007



When I try and parse a simple execute of a stored procedure in the Execute SQL Task Editor, I get the error:



"Object reference not set to an instance of an object"



Now, I ONLY get this error on my laptop, so I'm assuming it might be an installation error. I've tried to do the exact same thing in other environments, and received no error. Here's what I'm doing:



1. I create a simple stored procedure on a SQL 2005 database. Here's what it does:



create proc usp_testsp

as

begin

select 'whatever' ;

end



2. I create a new SSIS package in BIS.

3. I create an ADO.NET connection to the above SQL 2005 database

4. I pull over an Execute SQL Task item from the toolbox to the Control Flow tab.

5. I choose the ADO.NET connectiontype, the connection I created in #2, SQLSourceType of Direct input, SQLStatement is: exec usp_testsp, IsQueryStoredProcedure set to True. And I try ResultSet as both Single row and None



When I try to Parse the Query, I get the above error. If I still try to run the task in the debugger, here's what I get with the ResultSet set to None:



Error: 0xC002F210 at Execute SQL Task, Execute SQL Task: Executing the query "exec usp_testsp" failed with the following error: "Could not find stored procedure 'exec usp_testsp'.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.



And just so you know, I can execute the sp with no problems. And just to check, I granted execute to public on the sp.



And here's what I get with ResultSet set to Single row:



Error: 0xC00291E2 at Execute SQL Task, Execute SQL Task: There is an invalid number of result bindings returned for the ResultSetType: "ResultSetType_SingleRow".



I only get this on my laptop. I have SQL Server 2005 SP2 Developer Edition on Windows XP Professional, SP2.



Thanks,

Michael

Object Validation To Avoid Invalid Object Name Error

Sep 27, 2007



There are certain errors that does not come during compilation and it shows during execution because of late-binding concept implemented in SQL Server from 7.0 version.

The problem is when Tables are not there, SPs are created. And there is no option where we can set like 'Validate object resolution during compilation"

There are lot of SPs that are in invalid status because the tables are really not there and SP needs to be modified to reflect the correct table name. In Oracle, if I have to find the list of objects that are in invalid state (because of object resolution problems), it was possible. How do I do it in SQL?

I need a listing of all objects in my database that is in invalid state. Searched in NET but there seems to be no supporting tool also that lists invalid objects.

Pl let me know whether there exists a way by which I can get to know the invalid object lists in my SQL 2005 database
