General Exception and Module Load Err

jivemedia · April 15th, 2009, 12:46 AM

Hi Mitch,
Followed the book instructions, added your code to make sure it was correct , and have triple checked the manafest.

After I add the module to the page I recieve the following errors:

Setting a breakpoint on ViewGuestbooVB.ascx.vb produces two errors.

1. The class or CssClass is not defined
2. ResourceKey is not a valid attribute of element 'label'

Any suggestions?

It appears the manifest was propagating the text box below the source dropdowns with the control source loacation proceeded by spaces.

After manually selectung the source from the source dropdown for the 3 ascx files it now works.

A manifest example in the download would have been helpful.

TIA

I was not aware of any issues in the format of the manifests. The code samples are from my working development machine, I do apologize if there were spaces prior to the path of the controls.

I will try to review the download shortly.

jivemedia · April 15th, 2009, 12:52 PM

Hi Mitch,

Since the manifest in the VB folder is empty, I modified the one in the CS folder and got things working.

FYI - I had accidentally added the Settings.ascx to the Guestbook VB definition resulting in duplicate control keys on that definition.

I could not recover from the error and was forced to remove the module and reinstall.

During the uninstall process there was a syntax error thrown in the Uninstall.SqlDataProvider code. Sorry, I should have saved it for you.

The final concern is the inability to approve the moderated listing. Even though I am seeing the approve and delete links, by clicking approve does not show the listing to a non-registered user.

This is occurring while logged in as Host on FireFox and not logged in on IE.

I also noticed that even though I have configured the Sign Guestbook VB settings to moderate posts, after updating the settings the checkbox tick is not being saved.

Just tryin' to learn...

TIA

I will have to download the source and compare it to my local copies.

I am not sure of the issue, once you approve the items, do they disappear from the view for approval?

jivemedia · April 15th, 2009, 01:37 PM

No,

When logged in as host, by clicking approve the page just redirects.

Maybe it is not recognizing
SqlHelper.ExecuteNonQuery(ConnectionString, GetFullyQualifiedName("ApproveGuestbookEntry"), moduleId, entryId)

I can go directly to the SQL table and manually approve and delete, By doing so the results to the non- logged in user are viewable.

I can run the following script in host >> SQL

UPDATE dbo.[DNNModuleProgramming_VB_Guestbook]
SET IsApproved = 1
WHERE ModuleId = 382
AND EntryId = 2

And it works as expected.

The delete routine is also behaving the same way as described above.

If it will save you time...

If you need me to wrap up a zip of the project and send it to you - let me know

msellers · April 16th, 2009, 10:30 AM

My guess is that there is a translation error between the stored procedure name, and the code. I was just notified of a typo in the CS version, which had a missing p in approve.

Do you get any errors to the Event Log when you try to approve/delete an item?

jivemedia · April 16th, 2009, 12:39 PM

Hi Mitch,

No, the event log is not capturing any errors.

The link URL for the delete link is http://localhost/dotnetnuke/Guestboo...1/Default.aspx

The calling page is http://localhost/dotnetnuke/Guestboo...5/Default.aspx

I have not turned on HumanFriendly formatted URLS in web.config yet to avoid any URL format issues.

I can also try deleting the module to capture the uninstall.sqldataprovider DROP syntax error that was thrown during the uninstall process.

One thing at a time.

Let me know what else I can do to help debug.

TIA
Buck

Buck,

I'll try to take a look at this here either today or tomorrow. I'm not sure what the issue is, but I'll be sure to capture it ASAP. Sorry for the troubles.

I don't know if this is the same problem, but the approve and delete links in the ViewGuestbook control do not work... I ran the saved procedure in VS and entered the ModuleID and ItemID from the DB table and it worked fine... when I debugged by attaching to process I noticed that the ModuleID being passed to the stored procudeure was different... the db said 437 but we were passing 435... I changed in QuickWatch and the deletion worked... debugging further I noticed the following:

when we're getting the ModuleID for deletion I get 435 from this code in the ViewGuestbook control

Code:

int oSignModuleId = int.Parse(Settings["WroxModules_Guestbook_SignModule"].ToString());

but when we add an entry I get ModuleID 437 from this code in the SignGuestbook Control

Code:

oInfo.ModuleId = this.ModuleId;

looking at the db ModuleSettings table I see this:

ModuleID SettingName SettingValue
436 WroxModules_Guestbook_SignModule 435
437 WROX_Guestbook_AllowAnon False
437 WROX_Guestbook_EnableCaptcha False
437 WROX_Guestbook_ModerateEntries False

.... I'm still trying to sort this out, but we definitely have a mismatch between the ModuleID which we use to insert into db table and the ModuleID we use to try to delete an entry
