I created a new Setup project to my original project. In my project's code there is this line: Public DBPath As String = My.Computer.FileSystem.SpecialDirectories.MyDocuments & "Visual Studio 2008ProjectsFUV1FUV1FU.mdb" I just wanted to know, if I am instaling the project in other computer that has no VS in it, with the SETUP project, do I need to change this line? something to do with the Application Folder of the Setup project?

How I make SetUp for program in vb.net with local database(data base which include in visual studio.net 2008) to make it work in other computers which not have the visual studio 2008?
View 7 RepliesI am trying out the Visual Studio 2008 Standard Edition Setup and Deployment - Setup Wizard on a very simple VB 2008 app which includes a simple SQL Express dB. The build works fine and it installs on the target system ok. But when I go to run the application and add a new record for example, I get a "read-only" error indicating that the sql db is read-only. Yet none of the files in the folder are read-only. What is odd is that the folder that it was installed into "acts" like it is read only, yet it is not identified as such. If I move the .exe and db files out of that folder, (onto the desktop for example) it works just fine. Should I set up a post build event or something to make

In my development I want to use sql server with dataset.
When I finish the project at my development machine, I want the ability to install it at these 3 servers.
What is the best way to configure the connection?
Can I change the connection string created by the wizard during run time?
I am creating a VB windows form applications , the working can be summarized as users fills some form and data is saved in sql server database.Now the problem i am facing is that i have to deliver this as a setup file to someone, and that person will further distribute it to different users to run on their PC, what i am thinking is that the code once installed on other computers and executed will give errors because of the connection string of sql server db as it will not match with that computer . I know that if a distribute projects i can put connection string in app.config and every user can change it according to his/her machine .But as i am giving a setup file how to solve this problem

I'm guessing the connection string is wrong, I'm going to try the server as localhost, but in the mean time hopefully someone might see what I might be doing wrong.I'd also like to look into doing it asynchronously, so the UI doesn't freeze,
I am trying to open an Oracle database connection in vb.net 2008 in order to issue a Select statement and the populate a listbox with it.

Dim orclstr As String = _

"Data Source=10.0.0.77;" & _
"User ID=myuser;" & _

Obviously, I am doing something wrong, but I can't figure out what.
I've already finished the program and the last task was to add a password for my MS Access database. I've created the password in Ms Access and I've already modified the connection and saved the password but when I run the program all codes like this
Me.Table1TableAdapter.Fill(Me.Database1DataSet.Table1)got an error message says Not a valid password.
how i can create a connection to a database when i open my program and then close that connection when the program closes, so that the user has a permanent connection while the program is running that can be used for multiple things depending on what the user decides to do.
View 5 RepliesI am using VS 2008 VB and setup my application software in Win XP without any issue. But after installed in Win 7, it doesn't work well (it show one file not found, but I saw the file in the right folder). Could it be the incompatibility of VS 2008 and Win 7? If I upgrade to VS 2010, will the issue be fixed?

I know this topic has been addressed a million times but please help me out. I have read so many articles on HOW TO encrypt and decrypt the app.config file but I need to know WHEN and WHERE I should encrypt it.
The problem arose because we found an AppName.exe.config file on a users computer and the database username and password was clearly visible. I understand that the .config file gets created during the VB app install process and is used
by the application. I then learned about the aspnet_regiis.exe tool and ran it on the app.config file inside my VB project. I am guessing that was the wrong thing to do.
When I now install the app on user desktops, it gives an error stating failed to decrypt the connection string. Also, when one of my other developers attempts to open the project in his copy of visual studio on his computer, he receives an error when trying to access the setting portion of the project properties. We store all of our projects on a file server and any developer can access the projects via a mapped drive on their computer.
So how am I supposed to encrypt the .config file. If I can't encrypt the App.config file in the development environment, then I'm guessing I have to perform the encryption on the users PC during the install process? How do I do that? Or is that what I am supposed to do?
Just for reference, here is the aspnet_regiis command I ran.
aspnet_regiis.exe -pef "connectionStrings" S:ProjectsDevelopmentVB.netPTPUSourceCodePTPU -prov "DataProtectionConfigurationProvider"
One last thing, maybe it's my misunderstanding of the issue but if this problem has existed since .Net 2.0, why has an option not been built into the development studio to encrypt connection strings?. This would seem to be a very common issue, even their own dataset wizard creates connection strings that are clearly readable.
I have a piece of code connecting to my database retrieving data. I was just testing the form on another computer and everytime it loads this specific form it closes the form.You can see the lines I had to comment out in order for the form to NOT close on load.

I have some software that grabs information from a mysql server. However, users minimize it to the system tray, and leave it idle for hours until using it again.If a user leaves the program idling for about 15 minutes, then goes into the program again to perform a query, it throws a Fatal Error in the mysql, and says 'connection must be valid and open'
The reason is simply because the mysql connection has timed out..I was wondering what the code would be to re-connect to the server IF it has timed out.

I am storing my connection string in my app.config file. I am using sql server express 2005. The connection string on my dev machine is different from the ones at the clients. so each time I update I open the config file and edit the connection string setting. This is quite a pain.also I have now published my app to an ftp folder so that the clients can get the updates each time I make changes. saves me the hassle of going to them each time i update. so now i need it to be so that I won't have to change the setting all the time.Would the best way be to store the connection string in a settings table in the database?
