TransactedTeceiveScope not persisting when assigning value to a variable

Posted By:      Posted Date: August 29, 2010    Points: 0   Category :Windows Application
In a TransactedTeceiveScope I write to a DB table (via a custom activity SaveApprovalRequest using EF) and want to execute some other activities. With SaveApprovalRequest being the only acitivty workflow persistance works fine. As soon as I addionally assign a value to a variable the workflow no longer gets persisted. Why? I am using EF to write to a table in the same DB where . Below a minimal test case. With the assign activity the workflow does not persist. Without the assign activity the workflow does persist. <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.diagnostics> <sources> <source name="System.ServiceModel" switchValue="Warning,ActivityTracing" propagateActivity="true"> <listeners> <add name="svcTraceFile" type="System.Diagnostics.XmlWriterTraceListener, System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089" initializeData="X:\temp\Logs\ApprovalWorkflowTrace.svclog" traceOutputOptions="Timestamp"> <filter type="" /> </add> </listeners> </source> </sources> </system.diagnostics> <connectionStrings> <add name="approval" connectionString="Data Source=(local);Initial Catalog=Approv

Problem assigning a value to a variable in a Script Task

I've found loads of posts with the error I'm seeing: "The type of the value being assigned to variable [XXX] differs from the current variable type". However, I can't see anything that matches my scenario.  I'm simply trying to assign a value to a variable BEFORE passing the variable to an Execute SQL Task. I want to assign "true" or "false" to a Boolean variable called LogError, but as I got this error, I tried instead to assign 0 or 1 to it after converting it to an Int16 variable, but got the same result. I can see all manner of posts that make me wonder what I may have problems with next when I try to pass this variable to my stored proc that's expecting a BIT, but for now, I'd love SSIS to simply assign the value to the variable! Any ideas?

Script Component - Assigning value to a variable problem


I have a Script Component and in it I want to assign a value from a row to a variable. I am iterating through a For Each Loop, so I am only getting 1 row at a time. I have a variable declared as ScriptedSaleID and the following code in my Input0_ProcessinputRow method:



myvars As IDTSVariables100

        'We lock the variable for writing. 1st parameter is the name of the variable
        VariableDispenser.LockOneForWrite("ScriptedSaleID", myvars)

        'Now we can write the value to the variable
        myvars(0).Value = Row.SaleID

        'Now we unlock the variables

My problem is

FOR XML Blank Attributes missing end tag when assigning to Variable


Hi Everyone,

We have FOR XML Query that is giving the required XML with correct format when we are executing it within a stored procedure. Now when we are assigning it to a variable the attributes having blank value are being returned as single tag <Geography/>.

When not assigned variable, here is how output is looking like -



Local variable scoping in C#

In my previous post, Compiler-generated scopes for local variable declarations, I briefly touched on the issue of multiple meanings applied to the same name. In this post, I'll aim to flush out the compiler's rules with regards to binding names in their local scopes.

Compiler-generated scopes for local variable declarations

I was tasked with understanding and fixing a bug on error reporting with foreach iteration variables the other day, and it got me thinking about local variable scoping rules in C# in general. First, the bug.

Retrieving a variable from a previous page



I'm looking to have a search page where a user will select an item from a listview, then then taken to another page that wil display data based on their original selection.

A user will type in a string and be presented with a list of usernames that are like that string, when they select a user name who's profile they would like to view I would like the page that they're taken to, to be that users profile.

How would I transfer the variable from the search page to the profile page, and when I work on the profile page, how can I access that variable?


Embeb a variable number of videos


I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?

Hidden variable has no value


I know I have a valid solution, but the js is telling me that the value in the hdnRecordSaved variable has no value!
Even when I specify in my function the following, it still tells me it has no value:
var myTextField = document.getElementById('hdnRecordSaved');

When I put the full value of the variable in (ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value), I get the correct contents back ("1"), which I set in my code behind. However, I would prefer to just put the short name in since the masterpages may change, etc. Unfortunately, I know I can get around this with VS2010, but we are using VS2008.

What am I doing wrong with the js naming conventions that can't give me the contents? Here is my below js.

<asp:Panel ID="pnlMapFields" runat="server" ScrollBars="Both" Height="430px">

<telerik:RadTreeView ID="RadTreeView1" runat="server" DataTextField="Description"

DataFieldParentID="MapFieldparentID" DataF

Session Variable issues


Hello everyone,

I ran into an issud to day with the follwoing code.  The strPanelOrder session variable is false, however, once it goes into the next if statement and sets the strTrimOrder to True, it changes the strPanelOrder session varialbe to true as well.  Why is this and how to I stop that from happening?

If Session(strPanelOrder) Is "False" Then
                If (strItemNumber.Length() = 10) And (strItemNumber.Substring(0, 2) = "FS" Or strItemNumber.Substring(0, 2) = "FC" Or strItemNumber.Substring(0, 2) = "DS" Or strItemNumber.Substring(0, 2) = "DC") Then
                    Session(strPanelOrder) = "True"
                End If
End If
If Session(strTrimOrder) Is "False" Then
               If (strItemNumber.Substring(4, 1) = "T") And (strItemNumber.Substring(0, 2) <> "AC") And (strItemNumber <> "Length") Then
                    Session(strTrimOrder) = "True"
                End If
End If


Thanks in advance for taking a look at this.
