WF4 and DLL which is multi-threaded - fundamental question?

Posted By:      Posted Date: September 10, 2010    Points: 0   Category :Windows Application
From a CodeActivity, I'm calling into a DLL which internally uses AutoResetEvent to implement Two-way signalling.  This call, into the DLL, writes to a USB/Serial Port and then waits for the reply.  It isn't working. Is this because the WF4 runtime uses its own threadpool and can not interact with threads that were created before calling the CodeActivity?

question about multi user website and security



i am developing a multi-user website using Dynamic Data and wondered if someone could answer the following or provide advice:

what is the best way of protecting data so someone (who has a login to the site) cannot see records intended ONLY to be viewable by another valid user?

as far as i can see a user can simply tamper with querystring or url values (if using routing) and bring up the details of records they should not.


any help qould be gratefully appreciated. i am drawing a blank so far and the easiest option may be to back to a traditional asp.net site where i can control things simply by use of a Session variable (UserID)



question about multi rows update in SQL table


Hello, im tryin to do something without success. I have some SQL table with few columns (fileId(int), fileName, copies, color and finish), the page is build in a way, that the user upload few files (the files uploads to some folder, and the fileId and fileName are write to the above SQL table - so the other columns (copies, color, finish) are stay blank - which is OK!!!) after he finished uploading the files he can see the files names in GridView and in that grid view i put some textbox for copies, and 2 DDL for color and comments. I need to update the rows with the new data after the user click some button (the all rows) this is the code:


<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" BackColor="White"
                                        BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="3" DataKeyNames="fileId"
                                        Width="100%" Font-Names="Arial" Font-Size="X-Small">
                                        <RowStyle ForeColor="#000066" />
                                            <asp:BoundField DataField="fileName" HeaderText

Multi threaded Parallel Workflow



    I am in the process of designing a system that brings data from different sources, I was wondering if there is a way of executing the workflow in a multithreaded parallel environment. My scenario is as follows


We have 4 similar legacy databases one for each Geography (this is a legacy database, we cant merge the data for now), I am creating a front-end which will retrieve data from all 4 databases. I want to utilize workflow by executing the data in different databases in a multithreaded environment and combining the result. Is this possible?

Any help is appreciated



Multi-threading in .NET: Introduction and suggestions

This article uses the C# type shorthands throughout - int for Int32 etc. I hope this makes it easier for C# developers to read, and won't impede any other developers too much. It also only talks about the C# ways of declaring variables to be volatile and locking monitors. Developers using other languages can find the equivalents in their own preferred environment, I'm sure.

Web Site to Web Application Question


I've been building web sites and for my next project I will be creating a web application.  I use a 'BasePage' class in all my projects but, since web applications do not contain the 'App_Code' folder, what is the best place/practice for the 'BasePage' class?



connection string question from a newbie


when publishing  in the webmatrix dialogue it asks for "destination connection string" for my "database.mdf"

I was not sure what it was so I pasted this from my web.config file :

Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\database.mdf;Integrated Security=True;User Instance=True

it all published ok, but wont run, so I guess it has somthing to do with this connection string or some kind of configuration issue.

My question is this, What should go in the field for "Destination connection string"

Security Question Answer Retrieval


I know there is a method built in for retrieving the encrypted password, but how do I retrieve the encrypted security answer?

What I want to do is have a member profile update screen that the end user can update their password and security question and answer. However, when they get to this page, I want to already be showing the security question (the easy part) and its answer (the not so easy part).

I have updated web.config with passwordFormat=Encrypted and have added a machineKey with the generator (forgot the link, but located on eggheadcafe somewhere).

I haven't done ANYTHING yet, since I already have a user store with hashed information. I wanted to get some functionality done before publishing, wiping the store and recreating users (only a couple developers).


Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!




C#, LINQ: (List<>) Question???


Hi Everyone,

I have a strange problem:


There is an entity (Table) called "Filters" in my .edmx which has all my tables and stuff in it (to use it for LINQ queries)

I have created a class called "CustomFilters" which inherits "Filters". So now my cutom class has all the properties of the original "Filters" class (table) and 1 more additional property that i wanted which is a List of "CustomFilters":

List<CustomFilters> children = new List<CustomFilters>();

Now i get all my records into:

List<CustomFilters> theOriginalList = new List<CustomFilters>();

NOTE: first all records are tken into a List<Filters> and then these are added into List<CustomFilters> where List<CustomFilters> for children of that record is added, and then children of the child records, and so on......

so now, every record is an instance of CustomFilters which has a property named "children" which is a list again; and each child again has instanaces of "CustomFilters", and each instance again has children...and on and on and on.....

(basiacally its a data source for a treeview in my silverlight control)

every thing is good and working as expected.


linqdatasource parameters question



I'm currently getting to know the linqdatasource control. What would happen if several WHERE parameters are added to the linqdatasource control declaritively in the aspx page but no WHERE clause is defined? 

1. is there any issue with setting up multiple WHERE parameters in the aspx markup for linqdatasource but then deciding which ones actually get used at runtime by setting the actual WHERE clause at run time? Would the unused parameters simply be ignored and cause no issues?

2. when you need to modify WHERE clause or WHERE parameters at runtime do you need to do so in an event handler? such as linqdatasource.selecting?
I see from the above link it is possible, but is that the standard way to handle controlling filtering in code behind for linqdatasource?

2b. if you use an event such as linqdatasource.selecting to add where parameters and/or modify the where clause in code will that also break the builtin sorting and paging support of the linqdatasource with a gridview? 

database interface design question


For handy database interface, is it good to use SqldataSources exclusively intead of EntLib functions?

Thanks for any feedback.
