Hi all,

I've developed a PollControl add-on for the club site starter kit. You can find all information about it on this page:

Very tidy clean code Tom, cascading deletes, love those, keeps it all clean. It looks very good, I will try it out in the next few days. One comment - would use nvarchar in case somebody wants to react in Japanese or something

Um, my name is in your readme file - which I am flattered and glad to see that
IN NO EVENT SHALL MARK BRACEWELL BE LIABLE

Ha ha Lol!! ;-)

You're cool.

P.S. the Budweiser we get in the states is nasty, how about you send us a case of  Stella so we're all on the same (web) page ;-) ??

Answer 3

User-1941076836 posted

Damn! :-)

Well, it was late when I finished the PollControl last night. I had to do is a Search & Replace on your name in the readme file. :-D

Thanks for your feedback.

Very cool Tom,

Can't use it in VB site though,  sigh.........

Nevertheless great stuff,

Answer 6

User-1941076836 posted

Lex,

It's not that hard to convert the code to VB.NET. Just a matter of syntax...

It only takes time to convert it. If you search for C# to VB.NET convertors in your favorite search site, you'll definetly find some convertors.

Maybe I will convert it to VB.NET in a few days. Can't promise you when dough.

Greetz,

Tom

User380413204 posted

He Tom,

That would be great of course. Momentarily I am still busy with the links Mark gave me concerning RSS.

I am fighting at many (ASP) fronts at the same time, but being new at all facets almost the simplest of things (in the eyes of guys that can really shift some code, like you and Mark) ) are a hugh challenge to me.

Nevertheless I am enjoying it very much and occasionally get something right too.

Best regards,

Lex

I left Tom a private message about where he can get the VB code.

How's that RSS stuff coming?

Answer 11

User380413204 posted

Hi guys,

Thank you both,

It works like a charm. One of these days i'll try to convert the Poll_view page to VB so I can show the Poll in Default.aspx.

Also I am looking forward to the proposed alterations. I think they make sense.

RSS basically works (see other thread) Lots of cosmetic changes and improvements to be made still.

 

You guys rock,

Lex

Answer 13

User380413204 posted

Hi,

Ok, so i got a bit enthousiastic and tried to convert Poll_View from C# to VB.

The first section gives an enigmatic (for me anyhow) response: Tried a few Convertors, but gave the same error. (probably the same Convertor......) 

The rest it seems to translate fine (no obvious errors, but then again could'nt test it yet. Is this something you guys can easily solve?

Thanks in advance,

Lex

Original code: public partial class Poll_View : System.Web.UI.Page

Converter output:

Class Poll_View
   Inherits System.Web.UI.Page
    '
   'ToDo: Error processing original source shown below

I sincerely apologize for being an ass,

The whole exercise of converting Poll_Vies.aspx to VB was not necessary at all.

Just pasted the Control  <Club:PollControl ID="PollControl1" runat="server" /> at another spot and now it works fine, must have picked an awkward spot earlier.

I've put a new version (1.0.3) on my demosite for the clubcontrol: http://clubdemo.jpworks.be/default.aspx

Answer 28

User-1065173911 posted

Tom,

Thanks.  I have implemented your classes and aspx pages on my site.  I am having one problem with IE7.  IE7 throws this error when I click on the green rollover, Manage Polls button, on my default page when logged on as admin:

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

I get this error on my local server and remote server when rendering with IE7.  Firefox does not throw this error.  I read through the forum for a fix, but mostly found the workaround of adding

"<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode ="Never" />",

to the web config.  I have looked at a few other sites, but all recommend the same, or recommend using the same <machine> key on each server, but I am not utilizing a web farm or multitple server configuration.

Any ideas on why I would be throwing this error?  Hope this feedback helps and thanks ahead of time for any insight you can provide, or to anyone else who may come across this thread that may of had the same error and can lend some insight.

Awesome!

Great work Tom,

Ever more flexible your Pollsystem.

One small thing, but that might be a problem of my own, since I haven't yet thoroughly tested it.

When I leave Rank blank I get:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Line 84: } Line 85: Line 86: if (string.IsNullOrEmpty(e.NewValues["Rank"].ToString())) Line 87: { Line 88: e.NewValues["Rank"] = 10;

While the code seems to want to prevent an empty Rank control, or am I mistaken?

Best regards,

Lex

Answer 32

User-1941076836 posted

Hi Lex,

That's a copy/paste error. Sorry about that. You can just change it to the following:

        if (e.NewValues["Rank"] == null)
        {
            e.NewValues["Rank"] = 10;
        }

Just the same as in the DetailsView1_ItemInserting event handler.

Answer 35

User380413204 posted

This looks nice Tom,

 

Tried to convert the code of Pollcontrol.cs to Pollcontrol.vb but converter could not do the job.

One of the problems:  rlb.Click += New EventHandler(SubmitButton_Click)

 

Compilation Error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: BC32022: 'Public Event Click(sender As Object, e As System.EventArgs)' is an event, and cannot be called directly. Use a 'RaiseEvent' statement to raise an event.

Source Error:

Line 128: Dim rlb As RolloverButton = New RolloverButton() Line 129: rlb.Text = "Submit" Line 130: rlb.Click += New EventHandler(SubmitButton_Click) Line 131: Me.Controls.Add(rlb) Line 132: End If

Source File: C:\Webs\App_Code\PollControl.vb    Line: 130

So I guess my question is who can help me convert this into VB?

Thanks in advance,

Lex

Answer 36

User-1941076836 posted

Hi Lex,

Sorry, I forgot to convert it to VB.NET [:S]

But the problem here is the syntax. You need to use toe AddHandler keyword:

AddHandler rlb.Click, AddressOf SubmitButton_Click

I'll try to convert it to VB.NET this weekend. However it's a nice practice, if you did it yourself ;-)

Greetz,

Tom

Hi Tom,

Don't get me wrong, this was no demand on you per se.

I am at the moment trying to do it myself. Almost there I think

This is one of them

Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.RadioButtonList'.

Hi,

Just do what the exception is telling you:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
  <%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:
<configuration>
   <system.web>
       <compilation debug="true"/>
   </system.web>
</configuration>

Then you got more detailed information about the exception.

Alright!  Thanks Tom for pointing me in the right direction.

For all U others out there that are new to this, to get this to run on your PC, I did the following:
opened up SQL Server Management Studio Express
Connected up to my local Service
In the right side, clicked on databases
Right click on white area - select attach add
find the club.mdf table and then this part is done.
Close the app

In explorer, find the clubPoll.sql
double click on it - SQL Server Management Studio Express should open - connect in, and the sql should be there.
U will see "master" in the toolbar, change this to the "club MDF" that U just added in the first step.
hit execute and the sql will run and install Tom's tables.

User-1941076836 posted
Hi, Most likely the Question object is null. But I'm sure you figured that out yourself. You said that it worked well locally. Strange because the only thing that's different probably is your connectionstring to another database. Normally, the pollcontrol works just fine when there are no questions (polls) yet... You can try to change your connectionstring to the host's database and debug it locally. Greetz, Tom

Any ideas on securing this so that only people in a specific "Role" can vote?  Right now all they have to do is be registered.  I have the rest of the site secured so that I place people in a "HomeOwner" role before they can actually do anything on the site.  As implemented right now people can vote immediately after they register.  I'd like to keep it a little more secured to a role, but still be able to show the poll on the default.aspx page.

Thanks in advance.

Hi all,

I have installed the poll on my site but I have got two problems. I am using VB.Net and SQL Server 2005. Poll works fine apart from the Poll_view doesnt show the reactions and Poll_View doesnt show the list of polls? i know there is no data sorce on these pages? I think I may have to add these but tried that and think my SQL statements are incorrect.

 
Any ideas? is it because Im using VB.NET. I can manage polls as administrator okay and vote in polls etc?

Hello all. I just attempted to install the PollControl and ran into this error off right away:

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

 I downloaded the control 1-10-07

I didn't see any finally to this so I hope I can proivde a solution.
This problem only occurs in the versions 1.0.4 when "PollControl.vb" is being used. I conpared the cs and vb files and found that the VB code is a little off.

 

TO FIX THIS, do the following

Around Line 104 you should find an "End If" statement, this is right after an "Else" statement

Cut the "End if" statement

Paste the "End If" statement above the "End Sub" around line 204

IT should look like 

   "              adminLinkButton.Text = "Manage Polls"
                 Me.Controls.Add(adminLinkButton)
          End If"

      End if <!-- This is the newly pasted End if -->

End Sub

Thats it, It should work fine. The code was trying to load the Question when none was available.

I will attempt to email Tom so he can update his downloadables.

I love the PollControl add-on, but I'd like to be able to have a poll with more than one question.  Has anyone re-worked the code for this?

 

Thanks so much!
