Created MSI But It Does Not Exist In "C:Program FilesMyApp"?
Nov 30, 2009
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'm making a setup project for my application. I have a file, dbconnection.xml, that I want to be installed to C:Program filesmyAppdbconnection.xml regardless of where the user chooses to install the application. I've added the program files 'special folder' and have a subfolder, myApp, under that where I place this xml file.
For whatever reason, no matter where the user installs the application to, the XML file is placed in the install directory, not in c:program filesmyApp.

While I've previously many years of relational databases and procedural languages, I'm stumbling with Visual Basic. In this problem, the simple situation is that I have two files, parent and child. The primary key of the parent file (Area file) is linked by a relation to one of the two fields that makes up the primary key in the child file (Project file) (unique key is formed from 'area' and 'project'). I have the default table adapters created on both files. I have created two maintenance forms showing one each of the two files in datagrid view format.I can create some records in the Parent (Area) file, but when I try to create a record in the child (Project) file, using one of the valid key values from the Area file, I get the 'ForeignKeyConstraint [relation name] requires the child key values [actual value] to exist in the parent table' which I'm absolutely definitely sure it does.
I haven't done any actual coding for those two maintenance forms, just dragged-and-dropped the files from the data sources screen onto separate forms so it creates the controls itself. But I can't work out, if it already knows the data does exist because I can load it back in to the Area maintence form, why it can't check itself to find out the record does exist. Why does it think the record from the parent record doesn't exist? It does exactly the same thing, whether or not the database is in access or SQL Server Express. I have all the latest updates.

I created a VB.Net program in Visual Studio 2010 Pro. Everything runs fine in debug mode on my developement machine. I'm using setup builder installation and cryptolicensing for the license.dll. I have checked the setup program and all the files are installed on the test pc as required. The program was developed on the 4.0 client Framework. The problem is when I install the program on the test computer it will not open or run. No indication of why no messages, nothing. Can anyone steer me where to begin to find out why this is happening.

I right click at solution"my program name" and click rebuild solution. then i try to run again the setup, there is nothing happen after that(It remain like before amendment). Did I miss anything here? I have never used this method before and this is my first time using it.

I'm converting a bunch of FOXPRO / FOXWEB apps to ASP.NET.
The underlying DB is still foxpro (for the moment).
I am passing a table to some VB.NET code that I want to have converted to a CSV file and sent back to the client for download. And it works! Sort of ... It works sometimes, but at other times, instead of asking me if I want to download the CSV file, it just spews the file to the browser window. [code]...

Intended use of program:
1. User enters 1-3 websites they wish to monitor
2. User clicks go next to textbox with data entered, then button and a copy of form refered to as browse is created.
3. Form refered to as browse is directed to the url refered to on the form refered to as monitor, in the associated textbox(passed as a parameter to copyForm)
4. A timer is used to refresh the webpage every 10 seconds
What I wanted to happen was the program turn the associated picturebox in form1 green if page is loaded, and black is loading.

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)
[CODE]...
Loaded Assemblies:
Assembly Version: 2.0.0.0
Win32 Version: 2.0.50727.4918 (NetFXspW7.050727-4900)
CodeBase: file:/Q:/Windows/Microsoft.NET/Framework/v2.0.50727/mscorlib.dll
[CODE]...
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.
