VS 2010 Catching Errors On Database Connection

Oct 11, 2011

I have developed a windows forms application in vb.net 4 which connects to a MSSQL database. I have used the built-in tools to add the data source, data connection and data set. (Data->add new data source-> etc.) The application is installed on staff laptops which may or may not have network connectivity and may or may not be able to access the server on which the database is held. Obviously this is causing unhandled errors when the program starts and tries to make a connection to the database. (using windows credentials) Does anyone know where in the code the connection is made so I can go in and add some error handling? Or any settings I can change to get visual studio to handle the errors nicely?

Get A File Not Found Error?

Feb 3, 2010

I had the following piece of code working for the last few weeks and earlier today it seems stopped working.I have the code in a try/catchh block and in that try I create a file, "Build.bat" with code in it that will get it to do some oracle/sql wizardry

If File.Exists(Application.StartupPath & "Build.bat") Then
Shell(Application.StartupPath & "Build.bat", AppWinStyle.NormalNoFocus, True)
End If

After stepping through my code I noticed that the catch is executed at the shell line, so I put it in an if statement to see if the file exists and it always comes up as true, but on the next line I still get a File not Found error.

Try
Dim BatFile As New StreamWriter(Application.StartupPath & "Build.bat")
Dim SQLPLUS As String[co

IO StreamReader File Not Found - Error

Nov 8, 2009

I am reading a file from the default location. I request a file by name only using an InputBox. If the User types a file that does not exist I get an exception error. I want to be able to handle the problem by outputting to a list box that the file was not found. My Code is something like:

sr = IO.File.OpenText(fileName)
IF fileName <> "found"
Handle issue
Else
Continue Code

I want to run a check to make sure the file does exist in the default location but not sure how to get it done. I had seen the Public Shared Function FileExists but I am not quite sure how to make it work.

Merge Files - Error: File Cannot Be Found

Jun 6, 2005

In the old dos days you could combine 2 files as save to a third file:copy file1 + file2 file3. It still works in a dos shell. I did this: Shell("copy " & file1 & " + " & file2 & " " & file3)I got an error that file3 cannot be found. I know it doesn't exist I want to create it. So I created a bat file:copy %1 + %2 %3 and called it as such:Shell("ccopy " & file1 & " " & file2 & " " & file3). I still get the error that file3 cannot be found. First I don't see how it can tell from the shell that file3 is a file. How do I do this otherwise? Do I have to create a blank file before calling it?

VS 2008 Strange File Not Found Error?

Jul 20, 2010

I have a program that looks for a file named 'license.dat' upon startup. The program first checks the directory it's in, and if the license file isn't there, it prompts the user to select the license file with a file browser dialog. I have tested this code and confirmed it working in a number of different OS environments.Recently, I received reports from two users (one in Germany and one in Italy) that the program can't find the license on their computers, even though it is present in the program's directory and they manually selected it with the file browser dialog. The only commonality I'm seeing here is a lack of English OS, but beyond that I'm stumped.This is the code I'm using:

If System.IO.File.Exists(System.AppDomain.CurrentDomain.BaseDirectory + "license.dat") = False Then
File dialog code goes here

VS 2010 - Database File Cannot Be Found After Adding UserControl

Aug 30, 2011

After adding a UserControl to a form which access my database I get this warning:
Warning1The database file cannot be found. Check the path to the database.
[ Data Source = C:Program Files (x86)Microsoft Visual Studio 10.0Common7IDEDatabase.sdf ]
C:UsersUserDocumentsVisual Studio 2010ProjectsProject1Project1Options.Designer.vb2160

Thing is I never had a database at that location, my database is and has always been in MyDocuments in the Project folder itself. There is nothing anywhere in my code referring to that database! When I double click it I get sent to this line in the Designers window:
Me.Controls.Add(Me.BoxControl1)
Even though I get this error I can still access my database, so basically it does absolutely nothing except drive me mad! So how do I fix this?
