I have a business object with a set of public DataTables and Public Strongly Typed Dataset DataTable Types defined. When I add the business object class to the report as a datasource, only public System datatypes (int, string) show up. I added System.Data to the report properties Assemblies, with no change. Any ideas?
I have a Excel file as data source. On sheet 1 there are some header information. On sheet 2 are a quiet simple data table. Both sheets will be read into memory with SSIS.
Now i want to combine some header information with the data table.
VS05 How are dates removed / nullified? I have a SQL datetime field that is being editted via a datatable / adapter - The table structure defines the datetime as a date. From here I want to remove the date - i.e. write DBNull back to the database. Setting the Date to Nothing or .minvalue results in a min date exception and DBNull cannot be cast to the datetime either. R
I am still confounded with how to create a VIEW involving multiple DATATABLES in a DATASET. Could someone point out a MSDN page where I can see this working and how I go about doing this? Let me re-iterate - I want to create a VIEW that uses JOIN type statements that involves multiple DATATABLES in my loaded DATASET.
I dragged two tables into the dataset designer. And I have a query with a resultset over both of the tables (joined).Is there ANY way I can have a strongly typed datatable out of the resultset?The automatically created dataset adapters won't allow me to create a tableadapter or datatable for the joined resultset but for one single table at a time only.Any solution to that? Theoretically it should be possible since I don't "lose" any type information with a join.. why can't I have a strongly typed datatable over the resultset?The join is not very sophisticated. In fact it couldn't be any more simple.(I'm refering to my previously posted question at http://forums.asp.net/t/1220481.aspx)
Hi, I am new to Crystal Reports. I have a dataset with three datatables that are related. How can I do a subquery on these tables and display its result on my Crystal report ?
The test sub below operates on a SQL Server Table with an xml-type field ("xml"). The purpose of the sub is to learn about storing and retrieving a whole xml document as a single field in a SQL Server table row.When the code saves to the xml field, it somehow automagically strips the xml.document.declaration (<?xml...>). So when it reads the xml field back and tries to create an xmldocument from it, it halts at the xmldocument.load.I order to get the save/retrieve from the xmlfield to work, I add the <?xml declaration to the string when I read it back in from the xml field (this is in the code below).At that point the quickwatch on the string I'm attempting to load into the xmldocument is this:-----------------------------------------------------<?xml version="1.0" encoding="utf-16" ?><Control type="TypeA"><Value1><SubVal1A>Units</SubVal1A><SubVal1Btype="TypeA">Type</SubVal1B></Value1><Value2><SubVal2A>Over</SubVal2A><SubVal2B>Load</SubVal2B></Value2></Control>-----------------------------------------------------The original xml document string is this:-----------------------------------------------------<?xml version="1.0" encoding="utf-16" ?><Control type="TypeA"> <Value1> <SubVal1A>Units</SubVal1A> <SubVal1B type="TypeA">Type</SubVal1B> </Value1> <Value2> <SubVal2A>Over</SubVal2A> <SubVal2B>Load</SubVal2B> </Value2></Control>-----------------------------------------------------which seems to have all the same characters as the quickwatch result above, but clearly is formatted differently because of the indenting.THE FIRST QUESTION: Is there a simpler way to do this whole thing using more appropriate methods that don't require adding the xml.document.declaration back in after reading the .xml field, or don't require using the memorystream to convert the .xml field in order to load it back to the XML document.THE SECOND QUESTION: Why does the original document open in the browser with "utf-16", but when I write the second document back to disk with "utf-16" it won't open...I have to change it to "utf-8" to open the second document in the browser.Here's the test sub'============================================ Public Sub XMLDSTest() '=========================================== Dim ColumnType As String = "XML" '=========================================== '----------Set up dataset, datatable, xmldocument Dim wrkDS As New DSet1() Dim wrkTable As New DSet1.Table1DataTable Dim wrkAdapter As New DSet1TableAdapters.Table1TableAdapter Dim wrkXDoc As New XmlDocument wrkXDoc.Load(SitePath & "App_XML" & "XMLFile.xml") Dim str1 = wrkXDoc.OuterXml Dim wrkRow As DSet1.Table1Row wrkRow = wrkTable.NewRow '=======WRITE to SQL Server============== '------ build new row With wrkRow Dim wrkG As Guid = System.Guid.NewGuid TestKey = wrkG.ToString .RecordKey = TestKey .xml = wrkXDoc.OuterXml '<<< maps to SQL Server xml-type field End With '----- add row to table and update to disk wrkTable.Rows.Add(wrkRow) wrkAdapter.Update(wrkTable) wrkTable.AcceptChanges() '----- clear table wrkTable.Clear() '=======READ From SQL Server ============== '----refill table, read row, wrkAdapter.FillBy(wrkTable, TestKey) Dim wrkRow2 As DSet1.Table1Row = _ wrkTable.Select("RecordKey = '" & TestKey & "'")(0) '===== WRITE TO New .xml FILE =========================== Dim wrkS1 As New StringBuilder Select Case ColumnType Case "XML" '---if xml build xml declaration: '---add this to xml from sql table => <?xml version="1.0" encoding="utf-16" ?> wrkS1.Append("<?xml version=" & Chr(34) & "1.0" & Chr(34)) wrkS1.Append(" encoding=" & Chr(34) & "utf-16" & Chr(34) & " ?>") wrkS1.Append(wrkRow2.xml) End Select Dim wrkBytes As Byte() = (New UnicodeEncoding).GetBytes(wrkS1.ToString) Dim wrkXDoc2 As New XmlDocument Dim wrkStream As New MemoryStream(wrkBytes) wrkXDoc2.Load(wrkStream) '=========================================== '---- this just shows that the file actually was touched Dim wrkN2 As XmlNode = wrkXDoc2.CreateNode(XmlNodeType.Text, "ss", "TestNode2") wrkN2 = wrkXDoc2.SelectSingleNode("//Value1/SubVal1B") wrkN2.Attributes("type").Value = "This was from the xml field" '---------------- '------ update the encoding....otherwise the file won't open in the browser with utf-16 Dim wrkN1 As XmlNode = wrkXDoc2.CreateNode(XmlNodeType.Element, "ss", "TestNode") wrkN1 = wrkXDoc2.FirstChild wrkN1.InnerText = Replace(wrkN1.InnerText, "utf-16", "utf-8") '------------Now write the file back as an .xml file Dim wrkFilePath As String = SitePath & "App_XML" & "XMLFile2.xml" Dim wrkXW As XmlWriter = XmlWriter.Create(wrkFilePath) wrkXDoc2.WriteContentTo(wrkXW) wrkXW.Close() End Sub===============================
I'm writing a Windows application (Visual Studio 2005, c#) utilizing a local SQLExpress database. It consists of about 10 tables and I've created about 15 Stored Procedures to address various functions... I can run the update Stored Procedures interactively within the designer and the data tables update as designed. However, if I run the update Stored Procedures from within my windows application is where they fail. I get no error messages, if I return a rowcount variable from the Stored Procedure it tells me that one row was updated (SELECT @RtnVal == @@rowcount)... but when I open the subject table in the designer, there is no new data.
My update queries address both insert and update functions, so if it is new row of data, it performs the insert action, otherwise it updates an existing row.
I can query the data using my stored procedures to load default values into my windows form, I can search and find client records to display in the form... I just can't update records. I'm of the opinion that it is a rights issue, but I can't find any resources that address user access accounts with SQLExpress and windows apps. The current connection string for my local database is set for Integrated Security = true; User Instance = true
I've tried two approaches... one utilizes my stored procedure....
Both fail... which points to the only common point in both approaches, the connection string and user rights... but I can't find any place to address user accounts or configurations for windows apps.

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?
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. I have used the "Dim" statement as "Dim DaAuthorLogin as System.Data.SqlClient.SqlDataadapter and Dim DaAuthorLogin as New ......) at the start of the private sub generated by the event requiring the data.

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.

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

Some previous forums stated checking the webconfig file but the web config file look okay. Is there another way to fix this.
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?
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?
I am new at this and we encountered a problem. Can names in the public role be deleted? We have some names that need to go - however the delete option does not high light?
I am unable to deny DMV rights to public. I have already ran the SQL query successfully: "DENY VIEW SERVER STATE TO public" and "DENY VIEW DATABASE STATE TO public"
However when I check my master DB, the public still have rights to all the dm_***** objects. Am I doing it wrong or is there any steps I missed out? Can anyone help please? Thanks a million.
Is there a way to make a report public, to outside your domain users? We have a web application the users are authenticated in that is not in .NET and not using NT authentication and we want to have a report linked from inside the application that will pass the parameters in the URL. This is not very sensitive data and the report is using SQL authentication. We also don't want then to log in a second time for the report. Can this be done easily?
I'm actually using global public variables in the custom code of my reports.
Is there a "chance" that , if the report is executed at the same time by two users, values calculated for an user will be crushed by other user's execution ?

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 ?
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:
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.
