DB/Reporting :: Rdp Connection String From Database?
Sep 24, 2009
I have just written an application for myself and a few other users to use .rdp to connect to a number of servers, by clicking on the appropriate button. In the full version of the program I have two sets of connections one for when we are inside our vpn, which uses local ip addresses and DNS names; and the other which uses the external IP addresses and DNS names.This works quite well; if the user has stored credentials on their pc for the connection they connect straightaway; and if they don't the .rdp dialogue opens up with the server name/address filled in, ready for them to edit the rest of the required information.The problem for me is that this means I have to code 43 different Private Subs and then link the buttons; and I was hoping that instead of individually coding each connection, I could get the users to:Select by an option button whether the connection was internal or external

I have created a very simple Visual Studio .net 2002 VB# program. It consists of form1 containing a DataGrid bound to an Access 2007 Database using OleDbConnection1, OleDbDataAdapter1 and DataSet11.The location address of the Database will change based on the user so, I need to make the connection string variable. Problem is inserting the following string variable "source=" & strFileLocation & ";" creates a fatal error

I have been given the task of debugging someone else's program. It previously ran flawlessly on a 32-bit Windows XP system, but now we are steadily switching over to 64-bit systems and this program has "spit the bit" so to speak.
This is App.Config.xml
Code:
<configuration>
<appSettings>
[Code] .....
The problem is I don't know my alternatives are. System.Configuration.ConfigurationMananger.AppSettings doesn't work.
I've tracked the problem to the last line Con.Open().
Code:
Public Function get_quotes(ByVal strDBConnection As String) As DataSet
Dim con As SqlConnection = New SqlConnection(strDBConnection)
Dim strQuery As String = "SELECT qmpQuoteID FROM Quotes"
Dim da As New SqlDataAdapter(strQuery, con)
Dim dsQuotes As New DataSet("quotes")
Try
con.Open()
The error is "The ConnectionString property has not been initialized."

I've been working with VB6, 2003, 2005 and 2010 and I've always hardcoded my database passwords. Recently we ran into a problem where we would like to change all our db passwords for audit purposes. The problem is passwords for different dbs have been hardcoded in all our programs. How can I create programs going forward without hard coding the passwords in? I think I should be using a config file of some sort, but not sure how or where to start.

I have a connection string in my app.config:
Code:
connectionString="data source=.sql2008 ;Database=Database1; Integrated Security=FALSE; Persist Security Info=True;" />
How do I change to another database (one of many) without using multiple strings? Can I change while the connection is open?
Code:
Dim myConn As New SqlConnection(System.Configuration.ConfigurationManager.AppSettings("ConnectionString"))

I need my program to connect to a database within my application i.e.What I have:
m_cnADONetConnection.ConnectionString = "Provider=Microsoft.jet.OLEDB.4.0;Data Source = C:Documents and SettingsmeroneyfMy DocumentsVisual Studio 2008ProjectsAsset Manager 2008inDebugDatabaseAssetManager.mdb"
What I need is: m_cnADONetConnection.ConnectionString = "Provider=Microsoft.jet.OLEDB.4.0;Data Source = DatabaseAssetManager.mdb"
I have used:System.Windows.Forms.Application.StartupPath & "ImagesSystemDefaultImage.bmp"
for loading of images within the default directory. but this returns the app path but also includes "System.Windows.Forms.Application.StartupPath" in the string?

1.Establishing a connection to a database(preferably one that is inherit within the project and can travel with it)
2. Setting the correct references to the database ( I tried connecting via JET with windows 7 and I get an error that I cannot use JET)
3. Query the database (Access) with SQL, and return those results to a recordset.
4. Loop through the recordset.
5. close the database connection
6. Open recordset and write data to table.

I've created a small DLL, an addin for Autodesk Inventor, this addin saves some information provided by the user and the program to an access(mdb)database.The whole idea behind this is that it allows users to quickly find drawings, assemblies and so on.The DLL works great on x86 systems however it has issues on x64 because I used ado.net.In a attempt to solve it I forced .net to compile it with the target x86 CPU settings.
However using this I'm unable register the dll (C:WINDOWSMicrosoft.NETFramework64v2.0.50727RegAsm.exe /codebase SavetoDatabase.dll )It says its not a proper .net dll file and therefore cannot be registered.
is there any other access-database connection provider (like dao or ado.net) that works on a 64 bit machine? Or do I need to change from mdb databases to another type (like mysql)? because sooner or later all machines its running on will be converted to x64.Or do I need to register the dll in another way?I've also tried to replace the conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0 with ACE, with no luck however

My Ms-Access .mdb file is on my website. It is in the App_Data Folder
The current connection string is:
OleDbDataAdapter Da = new OleDbDataAdapter("Select * from SerialNo",
new OleDbConnection(@"provider=microsoft.jet.oledb.4.0;
data source=ftp://ftp.WebsiteName.com/App_Data/SerialNo.mdb"));
Where am I making a mistake in above connection string?

My query is not the straightforward connection to MS Access.I am using a third application that places all data in an Access database BUT recently they changed the database so that it doesn't end in '.mdb', instead in another suffix: '.accdb'.The database is still an Access database but I cannot connect to it using the connection strings:[code]Previously I was able to use the second connection when the database name ended in '.mdb' (Database Name.mdb).

I have an application that will be called by a database(this application is called from an access shell that uses SQL Server Tables), my question is do I need to provide a connection string to write to the database or since it is already open I can just pass the insert statement. If I am to provide a connection string do I use OLEDB JET 4.0 or ?

I just want to know what is your suggestion about storing database connection strings in .NET? I am using My.Setting usually, but now I am facing with versioning of my application. When I upgrade my application to higher version the value in My.Setting has been changed, it didn't remain as user has set before, but changed base on my machine's setting. eg. the value in My.Settings Version 1.0.0.0 (User's computer) is 'ABC' When I develop again some new feature on my machine and set its version to 1.0.0.2, of course the connection string in my computer's My.Setting file is different with User's computer's My.Setting. So when I copied my recent updated file to use's computer, then run the application, the application read the new My.Setting file from my computer but not from their computer. the value in My.Settings Version 1.0.0.2 (Developer's computer) is 'DEF' Therefore I have to reset and reset their connection strings onve I updated their application, that's too annoying?

I will be developing a program using visual studio 2008 with ms access 2007 as my database. What I only use is this type of connection string: "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:mydatabase.mdb;Jet OLEDB:System Database=system.mdw;" but i was asked if it is possible to put the database in sharepoint and I haven't even tried it before. The case is like this, the program that i will do would be installed on some computer units of different branches of the company then the database should be accessible through sharepoint so that every users can access the most updated database.

I'm trying to add a datagridview in vb.net, but it does not allow me to change the connection string or the database that should be imported to connect to it. The only thing that I'm seeing is the previous ms sql database that I connected with datagridview and everytime I click the new connection, the window closes and it leaves me with the datagridview with the previous connection that I have. And its not applicable because, now I want to connect it with mysql. Not ms sql. Its some sort of a cache like feature in vb.net, how do I get rid of it. so that I can add the new connection for mysql? Do I need to reinstall visual studio 2008?

For example, database A needs to be checked in every 5 mins and database B needs to be checked every 24 hours.
