Over the last couple months I've created a fairly substantial program for a friend in vb 2008 express to deal with the management of a fantasy football league, for its data storage it uses mainly an sql server 2008 express database for all the data, however there are a couple of text files for some unrelated fixed values.
I have spent the last week or so putting some vague finishing touches on it so that I can give it to said friend to test for me. However after working perfectly fine for me for the duration of the construction and also working fine on a couple of computers I installed and tested it on, upon giving it to my friend I find that (after installing) as soon as he opens up any form which relies on database data it spits out an error akin to the following:
Exception Text:
System.Data.SqlClient.SqlException: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

I have used a combination of LINQ and SQL statements to query and and update the database, with LINQ for querying and SQL for the updating, due to this most of the database communication is done through a LINQ to SQL datacontext using the pre-generated connection string in my app.config file: <add name="FFL.My.MySettings.FFLv2ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\FFLv2.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient" />
The only other time a connection string for the database is used is in an SQL execution function which uses the following: Dim connectionString As String = "Data Source=.\SQLEXPRESS;AttachDbFilename='" + Application.StartupPath + "\FFLv2.mdf';Integrated Security=True;User Instance=True"
The textfiles are also referred to using the 'Application.StartupPath + "folders/filename"' method
As for other details; I started this program on vb 2008 express but upon finding that the express version didn't have much in the manner of deployment facilities, downloaded a 90 day trial of visual studio 2008 pro to deploy the program as an msi install file. Operating system wise, I started the project on XP before converting over to Vista home premium + latest service pack (I think) which is what I've finished it on and am using currently, the 2 computers I successfully installed it on were both running XP SP3 and my friend runs a dualboot of Windows 7 and Vista (not sure what edition), he's tried it on both to no avail.
And for reference; to the above code/error, the database is called FFLv2.mdf and the project FFL.
The pre-requisites for my program (as highlighted by vb) are as follows:
.Net Framework 3.5 SP1
Windows installer 4.5
SQL Server 2008 express edition
I've tried changing the connection strings to specify a specific filepath, but that didn't help.

View 3 RepliesI am using VB.Net 2010 and calling a stored procedure with a dataset to get values in a table plus "created" values.
The values for the "created" values do not come across from the stored procedure. They all show as zero in the IDE and False for the variables. I know I am getting the record because the first five values come across from the stored procedure into the variables correctly.
When I step through a VB6 program using ADO the values are pulled across from the stored procedure.
The problem seems to be in the interface between a dataset and "created" fields in a stored procedure.[code]...

I have created an MSI. Before I install it, I look at "C:Program FilesMyApp" and it does not exist. I execute the MSI and look at "C:Program FilesMyAppData Base" and it contains my database with no data in it. I have checked it everyway possible. I open the app and stop it before the Fill dataset and check the connection string, it points to "C:Program FilesMyAppDataBase". I fill the dataset and it contains data from my previous install of the app. The database at "C:Program FilesMyAppDataBase" is empty. I use Windows explorer and check the database it is empty. I check the adapter and the connection string is "C:Program FilesMyAppDataBase". This is an Access database 2007 and the app is VS2008 in VB. It looks as though the installer is setting up a parallel environment somewhere.

I am still a beginner programmer so keep in mind that what I'm trying to do is beyond my knowledge but I have no one to teach me Visual Basic except from what little I can learn off of the internet. Currently, I am using Visual Basic 2008 Express Edition so my problem may be appear different if I show you any of my code.
I've created a program that contains a label and the words in the label form a question. Below that is a textbox with some text that has to be memorize for a play. Just think of the question as the previous speakers part. So far I've set it so that the words in the textbox are randomly removed and are replaced with a blank. I face with the program is that the user can't enter the answer because the blank is in the way.
Instead of putting a blank where the missing word is I would like to have some textboxes put there that way the user can enter the missing word and so that I can later insert some code that will let the user check to see if the answer they entered is correct.now the missing word is still replaced by the blank so I need to get rid of that and insert the textbox wherever the words are missing.
