i have a problem on dataset. i create two tableadapters and datatables because i must take from different datase fullname so it is showing this mistake "'System.Data.DataRowView' does not contain a property with the name 'TOID'."
my environment: VS2005, SQLExpress with SP1, WXP with SPs, the error msg I get is: 'System.Data.DataRowView' does not contain a property with the name 'change'. The base for all this is the 'MS Club Site' sample code downloaded from ASP.NET! After adding a new data field "change" to my DB I changed the StoredProcedure "PagedUpcommingEventList" (statement 31) and in the 'Repeater' I added statement 32 to reflect this change (see code below). When calling 'Configure Data Source' on the SQLDataSource I can read the DB (using the StoredProcedure) but I never see the new field 'change'! I certainly checked for additional StoredProcedures with the same name: "PagedUpcommingEventList" --- I definitely have only one in my project.PS: In another .aspx file using a SQLDataSource with a DataGrid; the field is showing up correctly! I spent days in the area of 'caching' without any success; thought the StoredProcedure is always called from the 'cache'! ....

Here's a new one I came across that stumped me for a bit. DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'xxxx'. It appears that one of my dropdown menus was referencing the old SqlDataSource1for its data source id. I had already changed the name of the of the id to something else though. To fix it, I just updated the reference to the new name.

I am having problems exporting data into a flat file using specific code page. My application has a variable "User::CodePage" that stores code page value (936, 950, 1252, etc) based on the data source. This variable is assigned to the CodePage property of desitnation file connection using Property expression.
But, when I execute the package, the CodePage property of the Destination file connection defaults to the initial value that was set for "User:CodePage" variable in design mode. I checked the value within the variable during runtime and it changes correctly for each data source. But, the property of the destinatin file connection doesn't change and results in an error.
[Flat File Destination [473]] Error: Data conversion failed. The data conversion for column "Column01" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
[DTS.Pipeline] Error: The ProcessInput method on component "Flat File Destination" (473) failed with error code 0xC02020A0. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
If I manually update the variable with correct code page and re-run the ETL, everything works fine. Just that it doesn't work during run-time mode.
I developed a simple custom control flow component which has several read/write properties and one readonly property (lets call it ROP) whichs Get method simple returns the value of a private variable (VAR as string). In the Execute method the VAR has a value assigened. When I put the value of ROP or VAR into MsgBox I can see the correct value. However when I execute the component I can not see the value of the ROP in the property window. I see the property but its value is empty string. For example when I put a breakpoint to postexecute or check the property before click OK in a MsgBox I would expect that the property value would be updated in SSIS as well. Is there a way how to display correct values of custom tasks properties in property window?
Untill recently I had a smooth running SSIS package,but suddenly it throws error syaing "OnError,,,,,,,The result of the expression
"@[User:trTextFileImpDirectory] +"SomeTextStringHere"+ @[User:trANTTextFileName] +(DT_STR,30,1252) @[User:taging_Date_Key]+ "SomeTextStringHere" " on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property."
I have child SSIS package running under a parent package (through execute package task)
I have few flat file connection managers in child package for text file import , in which I am building text file path dynamically at run time by assigning an expression in connection string property of connection manager. The Expression is as follows
Where @[User:trTextFileImpDirectory] is a variable which contains path of directory containg text files.Value in this variable is assigned at runtime from parent package's variable,which in turns fetch value from a configuration file on local server.
With my current configuration this path has been configured to some other server's directory over network ( I.e my package picks text files from some other servers folder over network)
While "Some string here"+ @[User:trANTTextFileName]" part of file name string.
(DT_STR,30,1252) @[User:taging_Date_Key] Contain the date of processing ,value in this variable is also picked up at run time from parent package variable.
1) So can someone give me some insight into possible reason of failures. 2) Is it possible that problem arises if directory (from which I m picking text files) is assigned password or is there exist some problem in accessing forlders over network ? 3) Or there can be some problem in package configuration at design time( I.e where I m assigning value in variable from parent package vriables)?

Currently, I have a WinCE application which uses the System.Data from NetCF and System.Data.SqlserverCE from MSSQL Server 2005 Mobile Edition. Now, I'm trying to use the System.Data.Sqlclient but I can't seem to find it in my System.Data. I notice that there are different version which is one from NetCF and one from the MS.Net framework itself.
Here's my question: Is it possible for me to use both System.Data? or should I only choose one. This is for my attempt to connect also from an SQLServer and connect to the local SQLServerCE as well.

Is there something I'm doing wrong?
I am importing data from xls file to a db table with a dts. In the time of the dts creation I am using 'Transform Data Task Properties' GUI window to map incoming xls fields (source) to the table columns (destination). Question: Is there any way to invoke the 'Transform Data Task Property' GUI window in dts runtime and use it to change the mapping dynamically in the run time? Thanks, Vadim.
I have this Stored Procedure: Create PROCEDURE ListEventas If MONTH(GetDate()) <= 6 Begin SELECT EventTitle, EventDuration, (CASE WHEN MONTH(StartDate) = 1 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Jan', (CASE WHEN MONTH(StartDate) = 2 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Feb', (CASE WHEN MONTH(StartDate) = 3 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Mar', (CASE WHEN MONTH(StartDate) = 4 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Apr', (CASE WHEN MONTH(StartDate) = 5 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'May', (CASE WHEN MONTH(StartDate) = 6 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Jun'FROM dbo.tblEvent INNER JOIN dbo.tbl ON (tblEvent.EventID = tblEventdate.EventID)WHERE YEAR(StartDate) = Year(GetDate())group by EventTitle, EventDuration,StartDate,EndDateEnd Else BeginSELECT EventTitle, EventDuration,(CASE WHEN MONTH(StartDate) = 7 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Jul', (CASE WHEN MONTH(StartDate) = 8 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Aug', (CASE WHEN MONTH(StartDate) = 9 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Sep', (CASE WHEN MONTH(StartDate) = 10 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Oct', (CASE WHEN MONTH(StartDate) = 11 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Nov', (CASE WHEN MONTH(StartDate) = 12 THEN Datename(Day,StartDate) + ' - ' + Datename(Day,EndDate) ELSE '' END) AS 'Dec'FROM dbo.tblEvent INNER JOIN dbo.tbl ON (tblEvent.EventID = tblEventdate.EventID)WHERE YEAR(StartDate) = Year(GetDate())group by EventTitle, EventDuration,StartDate,EndDateEnd When I execute it in the SQLExpress, the result returned as expected. But when I bind to Gridview I got this error: A field or property with the name 'Jan' was not found on the selected data source. How do I solve this? I am using drag and drop SQLDatasource to call the Stored Proc and VB.net is the language. Thanks
I've created a Union All data flow task which unions string fields from a couple of queries. I found that I needed to increase the length of the string field in the queries. Increasing the length causes an error in my Union All task. I can't seem to find a way to change the property of the fields in the Union All task. Most of the other data flow tasks have an advanced editor where I can change the length or type of the fields on the input and or output. I can't seem to find this for the Union All task.
Is there any way short of deleting the Output column and recreating it? (I like the order of my original output columns)
I am having trouble with using disable property in the expression for data flow task. Here is the issue as explained below-
lets say i have 3 tables TableA, TableB, TableC from which i need to export data. So i create a table (TableList) where I save these table names and a unique id to these tables. e.g.
in the ssis package select these tableNames & Ids from tableList in Execute SQL Task. And assign the result set to a variable object (@TableList.
Then i use For Each Loop Container (For Each ADO Enumerator) , to loop through these tablesnames & iDs
Inside this loop container, i define three data flow tasks one for each table. So i have DataFlowTaskA (For TableA), DataFlowTaskB(For TableB), DataFlowTaskC (For TableC).
Now for a given table selected in the iteration, only the corresponding DataFlow Task should be exeuted. e.g. For the 1st iteration, if TableA is selected then only DataFlowTaskA should be executed and DataFlowTaskB& C should be skipped.
In order to achieve this, I am using a 3 variable @FlagA, @FlagB, @FlagC (type Boolean) one for each Table. and use the value of these flags for the "Disable" property of the data flow task (so @FlagA will be used for Disable property in the Expression for Data FlowTaskA, and so on..)
SotThe First Step inside the Loop, I use Script Task. (Input for the script task: read variable is @TableID and Read/Write varaibles are these 3 flags)
In this script task, I initialize these flags to true or false appropriately. So this is what i do
If (Dts.Variables("TableID").Value.ToString = "1") Then Dts.Variables("@FlagA").Value = False Else Dts.Variables("@FlagA").Value = True
End If
If (Dts.Variables("TableID").Value.ToString = "2") Then Dts.Variables("@FlagB").Value = False Else Dts.Variables("@FlagB").Value = True
End If
So in the 1st iteration, (if TableA comes) @FlagA=False and B&C will be True. So the Disable property for DataFlowTask will be set false and for others it will be set to True. Thus, only DataFlowTaskA will be executed.
And this action should be repeated for each input table. this is the logic.
However only for the 1st iteration(say TableA is selected) it behaves as above. i.e. DataFlowTaskA is executed and DataFlowTaskB & C are skipped. But in the 2nd iteration(say TableB is selected) , it again executes DataFlowTaskA and doesnt exeute B & C (where it should have executed B & skipped A&C).
I do set daelay validation to true for all these but it still it doesnt working as expected. Even I checked the values for all the flags for each iteration and they seem to get the correct values. But somehow Diable propery in the expression not behaving as it should.
Am i missing anything. Do i need to set any other property to make this work.
The default Engine Thread property of a data flow task is set to 5, is this the best setting? what if I would like to run complex data flow tasks on multi-processor machines, should I increase the engine thread? If so, then what is the recommended Engine Thread number for running complex data flow tasks in a multi processor system?
Even if i am running simple data flow tasks on a multi processor machine, should I change the engine thread?
I am putting together an invoice for my company. I have a text box describing each section of the invoice, followed by a table to list out the charges. I am using multiple tables based on what type of charge the client is receiving.Â
I would like to hide each section if there are no items purchased of that type. I can do this with the table using the expression "=CountRows() < 1", but I do not know how to refer to that table (call it Tablix1 for the sake of discussion) for the text box. I've tried using a ReportItems function as my basis, without success.Â
I have a matrix table with a rectangle in the data cell. The rectangle has an image and textbox. The textbox has an expression in it's Hidden property based on the column name. The report renders fine on screen. When the report is exported to Excel, CSV, XML the textbox contents are not output (the images display as expected). I've tried setting the DataElementOutput to Output/Yes with no success. Exporting to TIFF, PDF, Web Archive/MTHML is fine.
I am using a stored procedure which returns a value of charecter datatype 'V' to the calling program.I am getting an sql exception System.Data.SqlClient.SqlException: Syntax error converting the varchar value 'V' to a column of data type inti didnot define any int datatype in my tablethis is my codeSqlCommand com = new SqlCommand("StoredProcedure4", connection);com.CommandType = CommandType.StoredProcedure; SqlParameter p1 = com.Parameters.Add("@uname", SqlDbType.NVarChar);SqlParameter p2 = com.Parameters.Add("@opwd", SqlDbType.NVarChar);SqlParameter p3 = com.Parameters.Add("@role", SqlDbType.NVarChar);p3.Direction = ParameterDirection.ReturnValue;p1.Value = username.Text.Trim();p2.Value = password.Text.Trim();com.ExecuteReader();lblerror2.Text = (string)(com.Parameters["@role"].Value); can your figure out what is the error ? Is it a coding error or error of the databse

Hey All, I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form. I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.
