I'm trying to do something that I'm considering quite simple but it does not seems to work.
Basically, I need to start workflows, persist them right away and pick up it from another machine (host).

Does call to StopRuntime method on the Workflow Runtime also releases the lock hold on an instance in persistence store by this runtime.
or the instance is locked for complete duration
I have a state machine workflow having around 15 states. In few of the states I am using SqlWorkflowPersistenceService to persist the workflow instance into the database. Workflow is using WorkflowInstance.Unload() method to manually persist the
workflow instance and UnloadOnIdle is set to false. Workflow service is hosted as WCF service on a windows service.
Problem: The states which implements SqlWorkflowPersistenceService to persist the wf instance calls another WCF service (which may take a lot of time) and then persists the instance. WCF service when finished with its processing responds the
Workflow service by calling the operation contract associated with the Receive Activity in the next state of Workflow Service. Everything runs fine if the WCF service takes some time to respond the Workflow back. But sometimes it happens that WCF service
has nothing to process and it responds immediately to the workflow, in this case workflow throws the error
"Workflow with id “xxxxx” not found in state persistence store."
What I think here is when WCF service reponds back to the WF immidiately then WF is still busy in persisting the WF instance. WF Runtime finds no wf instance in memory and checks into the persistance database. Since WF instance is still in the
This is quite strange. here is the issue:
1. I'm using a multi-select jqgrid.
2. I have my own delete button to delete multiple orders
When i press the delete button on the pager of my jqgrid, the records are deleted from the database but JqGrid shows some records (4-5). On refreshing the grid, correct numbers of records are shown.
Here is the code:
I need to store more than 4k of bytes in my SQLCE 4 database. How can I do that with the ASP.NET Web Pages 1.0?
1: The Microsoft.Data provider fails when I try to populate a parameter with more than 4k bytes.2: Referencing SqlServerCe assembly and using SqlCeConnection/SqlCeCommand/SqlCeParameter throws exception: SQL Server Compact is not intended for ASP.NET development.
How can I somehow map the generic DbType, which does not have NText as an option, to the ntext column in my database? (SqlCeParameter supports DbSqlType, which has ntext, but see problem #2)
Can anyone tell me the best way of storing Japanese characters through ASP.NET.I have to put characters into a asp:textbox on one page, which saves it to an Access DB.On a second page I want to display the content in a asp:label.
Should I store the characters directly to the database or should they be encoded, andhow do I encode the characters?
In my web.config i have:
<globalization fileEncoding="ISO-2022-JP" requestEncoding="ISO-2022-JP" responseEncoding="ISO-2022-JP" culture="ja-JP" uiCulture="ja-JP" />
On the display page I have:
<meta HTTP-EQUIV="Content-Type" CONTENT="text/html;CHARSET=shift_jis">
My problem is whenever i execute my app the first page that loads is the login page pointed to by my web.config file forms authentication, this page is meant to show CSS formatting for the info i am displaying but it is not. Any help with this problem would be great. A cut and paste of my problem is shown below as you can see there is no CSS.

Handheld device users need to be able to synchronize with a main data store when it's convenient and, preferably, when the back-end database server isn't busy. SQL Server 2000 Windows CE Edition allows you to build a traveling data store that can be displayed and run on a variety of devices. SQL Server CE supports a subset of the full SQL Server package, and can be used as a standalone server or in tandem with SWL Server and IIS. The architecture of SQL Server CE, along with data manipulation, synchronization, and connectivity issues, are discussed in this article. Topics such as making your data public, choosing the right type of replication, and handling errors are also covered.
