Store The Connection String In The App.config File That Include The Application.startup Path?
Nov 6, 2009
I'm creating window application with VB.NET and flatfiles.the problem is how do i store the connection string in the app.config file that include the application.startup path?
I want to ask that where to store connection string in VB.Net.AS in ASP.net we can store connection string in web.config file and access it in the foll. way [code]In VB.net where to store conn. string on form_Load or any other place???
I'm stuck regarding to grab connection from app.config file...i'm surf many type and kind to do it..but still can',t.....i need to connect into two database (oracle n firebird).
I need to know what is the common way to store a SQL server connection string for an application in VB.NET.How do I read app.config values How to do it in ASP How do I store a connectionstring (unencrypted thus unsafe)It's quite frustrating not to find a decent and full answer on how to store a connection string in VB.NET in app.config (or settings.settings if it's better) safely. At the moment it's hardcoded and so it is immobile and in plain text.
I have a connection string in my database which I read throughout my VB .Net application. I have another string which is NOT a connection string though. It instead has information about a domain on LDAP. So LDAP string just needs to be stored in the web.config as a string, and also to be retrieved as a string.
I have classes that get the connection string the the .config file through ConfigurationManager. They work great in the actual application. When I use them in a unit test with nUnit I recieve an 'Object referance not set to an instance of an object'. I also tried to see if nUnit would read a ConfigurationManager.AppSetting and it failed too. Is there a configuration or workaround for this?
I been working on a Printer INK Management Program for my Company. We have many different districts we deal with. Each district has a different Server.I am trying to create the application where they can place the database file anywhere they would like on the server and when they first run the application it would ask them to choose the location of where they placed the file.I would like to know how i would be able to edit the connection string information in the app.config file during run time.
I want to write the connection string of my application in app.config file. I dont know how to write it or how to dynamically change it from my application source code either. My App.config file shows like..
I'm facing a problem after installation any software setup that has a database in access(mdb file) How to I transfer file path in our connection string.
I've been getting this error when I try and use my model container:
No connection string named 'PFModelContainer' could be found in the application config file.
I have my edmx file in a separate project. I checked the app.config file and my model was there, and I also put it in my main project app.config file. Still doesn't work. Here's the connection string:
I have a question about the App.Config file. My understanding is that the connection string is stored within this file. I have setup my application so that the App.Config file is not only written to c:users<username>appdatalocal but also to c:users<username>appdataoaming. I plan to encrypt the connection string, my question at this point is will it encrypt the connection string in ALL copies of the App.Config file? It looks like at this point that the App.Config file is stored in two places on the hard drive.
Dim dbconn As OleDbConnection Dim DBCommand As OleDbDataAdapter Dim DS As New DataSet dbconn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:COLORsitedataCUFORHDR.dbf;Extended Properties=dBASE IV;")
[Code]...
I prefer SQL server but im afraid in this app I have no choice. I think the .DBF file is v III dBase according to a thrid party .dbf viewer. The code explodes on the DBCommand.Fill(DS) line, telling me I have provided and invalid file path. The path is good to go.
Should I be using a driver with a different provider? When I remove the Extended Properties parameter I get an error unrecognizable database format - hinting in this case the path is correct.
Private Sub save() Dim con As New SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=D:Chuttu VBProjectsLICLIC.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True")[code]......
For example i have form within the application which shows the connection string in a text box so the user can change it to there database but i cant work out how to save the new string to the connection string within the app.config file
For the first time for my project i have saved the connection string in config file. i have created a new config file by the name of SQL.Config and used it in app.config <connectionStrings configSource="SQL.config"/>
I have been reading/researching/taking advice on connecting to my db by storing the connection string in my app.config. I have the connection string named "MyDB" in my app.config file. However, I cannot figure out how to use it in my code. I use mySQL. I added the configuration.dll reference. How do I pull the connection string from the app.config file and open a connection with it?
I sent the application exe to a user to test and they get an unhandled exception error and the details show my personal My Documents Folder/DEBUG path from the project. So I tried to use Application.ExecutablePath but when I release that it points to "My Documents" Folder (not the debug) folder. The file to open is in the same folder as the exe is in but for some reason the error occurs because the application is not looking for the file using the path where the EXE was launched from. Here is my code that relates to the section giving my users a problem:
from the module Public Class shrd Public Shared ocSess As cSession
[code]....
How can I get the application to open the file that is in the same folder as the exe when the user launches
I have a connection string (which works fine) to connect to AD through my web application in my web.config. Traditionally, however, I've created a new connection to pull info. from the user after login like so:
Using adDirectory as New DirectoryEntry("LDAP://OU=myou,DC=mydc,DC=dc,DC=com") Dim adTicketID as String = ticket.Name myVar = "adDirectory.Children.Find("CN=" & adTicketID).Properties("myproperty").Value End Using
It seems that I should instead use the connection from the web.config like so:
Using ADCS as New DirectoryEntry Dim adTicketID as String = ticket.Name myVar = "adDirectory.Children.Find("CN=" & adTicketID).Properties("myproperty").Value End Using
Is this possible? How would I accomplish it so that I don't need to constantly create new directoryentries?
You will find attached the source code of a small program. I wanted to know if it was possible to modify the connection string in Web.config and use a connection to MySQL. I made some attempt, but does not connect.
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.
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 tested my code in a windows form project and it works great. so now I want it to run as a service.The problem i have is referring to "name" in my configuration string which is in app.config.
Dim settings As ConnectionStringSettings = _ ConfigurationManager.ConnectionStrings(Name)
(Name) is under-squiggled and message name is not declared, file IO functionality is available in the microsoft.visualbasic namespace.
The reason I ask is that I want to print, at run-time, a file in the application's resources, like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim printProcess As New Process printProcess.StartInfo.FileName = "C:UsersGeoffrey van WykDocumentsCountdown_Timer_Help.rtf" ' printProcess.StartInfo.FileName = My.Resources.Countdown_Timer_Help printProcess.StartInfo.Verb = "Print" printProcess.Start() End Sub
The reason I ask is that I want to print, at run-time, a file in the application's resources, like this:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim printProcess As New Process printProcess.StartInfo.CreateNoWindow = True
[code]....
When I use "C:UsersGeoffrey van WykDocumentsCountdown_Timer_Help.rtf" as the argument of FileName, it works. But when I use My.Resources.Countdown_Timer_Help, it says it cannot find the file.
