I loaded the trial and the sample databases into SQL Server 2005.



When I try the "Browse Dialog Advanced", "IsDirty Changed Event" or any of the demos I get:

**********************



Interestingly, when I close the Error Dialog, it looks like the Browse Dialog demo works and it can get data y choosing "Browse" or "Browse as Lookup".



However, most demos do not work and all give me errors.



I thought I entered my database credentials incorrectly, but found nowhere to change what I entered. So, I uninstalled StrataFrame. That led to another problem. It hung on Unregistering assemblies. I then moved the open form and noticed an error message that the uninstall path for 2005 templates could not e found (that makes sense because I am using VS2008, not 2005) but it does not make sense that an error dialog is not displayed in front of other forms. After clicking okay, it then uninstalled correctly.



However, I reinstalled StrataFrame (and I ensured the Program Files directories were removed) only to discover my credentials PERSISTED BEYOND THE UNINSTALL!



I looked here on the forum and found the reference to connection.dat... IT IS STORED IN THE HIDDEN APPLICATION DATA DIRECTORY!



Why? I suggest moving it to a non-hidden and expected directory... at least clean up the application data directory when uninstalling.



Anyway, I was then asked for my credentials again, where it is clear that "ad" credentials are tested, so it wasn't a login/access to SQL Server problem.



That leaves me with a demo that is not working and crashes on every demo from the Sample Console.



How do I get this resolved?



TIA

I am beginning to suspect that the Demo is trying to use Integrated Security even though I specified a Username and Password for SQL Server.



FYI: My test server will not accept Integrated Security connections.



...just a thought... its not good trying out a broken demo.

Hi Trevor,



The Connections.dat and AppKeys.dat files are in this folder:

%ProgramData%\MicroFour\ConnectionData




If you connection is not correct, just delete above files and run the demo again.

I think you missed my point: I found those files, deleted them and re-entered my connection info. It didn't fix the problem.

Hi Trevor.

Welcome to the comunity. You will find that people around here are extremely friendly and will do their best to help you out.

One thing that could help at this moment would be to try and get some variables out of the way, so we could concentrate on the StrataFrame features through the demos. Maybe you could set up a testing machine or even a virtual machine and have a fresh install, this way you would have total control of the environment and would certainly be able to run the demos. If you don't mind this, go ahead and we will all be ready to go step by step on the way.

Hope it helps.

Cheers.

You are right Hehe so let's try again....



Based on your error:

SqlException

Invalid object name 'customers'.


The customer table is not being found. Make sure your connection string is pointing to the StrataFrameSample database and that the user have rights for this database and try again.

I have multiple projects with other tools that access the database just fine. I enabled Windows Authentication and tested access to the database.





Consider this:



1) The user account can access that database and get access to SQL Server (I tested named pipes and TCP/IP). The account has been mapped to the database.

2) Again, with the "Browse Dialog Advanced Demo" - After getting the error, The demo WORKS - it accesses the database AND all the records are available.



Hmmm.... I am now wondering if this is a case sensitivity problem. This SQL Server instance is case-sensitive and (just thinking out loud) it appears that the items failing are referencing the wrong case (I.e. customer versus Customer, or rl_role versus rl_Role). I also happened to notice that the browse dialog test will find all the "Smith's" only if I type a search with a capital "S", not a lower-case "s".



looking into it...

Okay, that is definitely the problem: case sensitivity.



I opened the Visual Studio solution for Role-based Security and tried to open the Customers form. I get the same error: that "customers" is not a valid object. I changed the code from this:

      

public void FillTop100() {

this.FillDataTable("SELECT TOP 100 * FROM Customers");

      }

Arghh!!



Okay, hit post by accident.



I changed the case from above from "customers" to "Customers" and it worked.



So, the demo will always fail with any SQL Server instance set to be case-sensitive.

Well, that is a new one for me.



Anyway I am glad at least you found out why it was failing, unfortunately I have no idea how that "case sensitive" stuff can be controlled either by the server or the connection string, hopefully somebody from StrataFrame will be able to comment on this one.
