Change Connection String At Runtime?
Dec 2, 2009I'm writing a windows form application using vs2008. I need to connect to different SQL server express database files during runtime. There is a "how to do" video showing a technique for this
[Code]...
and then in the Form1_load sub and before calling the data adapter to fill data, insert codes below:
Dim strConnectingSting = NewConnectionString
My.Settings.RunTimeConnectionString = strConnectingSting
The method works but only for the first database. I found once adapter.fill is called and the connection to a database is established, the connection can't be changed.To do what I want, I have to create a startup project to call my main project. When I want to change connection, close the main project and start again.

Runtime Change On Connection String?
Apr 30, 2010I have read through some other post and haven't been able to find an exact answer that I am looking for. I have a connection string saved in my.settings that I am using. My database is residing on a server. Now I am going to have to install this application at more then one area and they will have the database on their server. What I am wanting to do is for the application when it is loading to search the network to find the database and return the connection string without the user having to do anything. I know with a web application you can search the machine you are on for the connection string without knowing its location but was hoping there was some feature like that to search the network to find it.

Strongly Typed DataSet Connection String At Runtime?
Oct 6, 2008I'm sorry but Microsoft did not think about this very well. I have used the dataset wizard to connect to my sql server and the connection string was placed in the app.config file. The only problem with this is that you can not write to it nor change string at runtime. So I need a way for each one of my users to specify their connection either during installation or after installation. I would appreciate any help in this matter.

Jun 28, 2010I need to be able to change the connection string of a strongly typed dataset at runtime. I have gone into the settings.vb page and written this code:

'This class allows you to handle specific events on the settings class:
' The SettingChanging event is raised before a setting's value is changed.
' The PropertyChanged event is raised after a setting's value is changed.
' The SettingsLoaded event is raised after the setting values are loaded.
' The SettingsSaving event is raised before the setting values are saved.

The way the code is suppose to work is that when a user logs in, the application gets the user's site ID (gvUserSite), then uses that to set the connection string. But when I log on with a SiteID of "21" it always uses the Case Else value. Also when I set breakpoints in settings.vb the application never stops on the breakpoints I set during runtime. As if the breakpoints were never set. Also if I put any code in the "MySettings_SettingChanging" in settings.vb I get a runtime error
"The debugger cannot continue running the process. Process was terminated.
Changing A Connection String At Runtime For A Tableadapter That Was Created Using The Wizard?
Jun 21, 2010I've created two forms of which two separate datasets/tableadapters were created by adding a datasource and dragging and dropping the fields onto my form.I was testing the program using a db that was located on my local drive. Well after publishing the app to the users machines, I noticed that the binded information was still being pulled from my local machine and not the database that the user is working off of.I've set the connection modifier properties for both tableadapters to Public, and I have written the following attempting to change the connection strings:
Private Sub btnSaveSettings_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveSettings.Click
Dim pap As New frmPap
My.Settings.dbLocation = txtSettings.Text

Change Connection String From Class Library In Main Application At Runtime?
Jan 16, 2009You can change the connection string at run-time like this. You make the connection string setting available for writing as a separate property inside the MySettings class:
Partial Friend NotInheritable Class MySettings
Public WriteOnly Property RunTimeConnectionString()
Set(ByVal value)
[code]....
Then, in some place when the application is being initialized (before using any table adapters of typed datasets), write something like:
My.Settings.RunTimeConnectionString = My.Settings.ProductionConnectionString
Where ProductionConnectionString is a simple String setting. It is a User Scope setting so every user can change it (by assigning a value to it, similar to the code above) and save it by calling My.Settings.Save()This code works well for connection strings which were initially created in the main project and stored in it's settings (= app.config file).
The connection string in the app.config actually has a longer name: MyApp.MySettings.MyConnectionString.When you have a connection string stored in the app.config in a class library project, and reference that project in the main project, the app.config files will somehow be merged, so the class library has it's settings.The thing that don't know how to do, is change a setting from the class library at run-time. I could copy the connection string setting from the class library to the main project's app.config. I must keep the same name, which looks something like: MyClassLibrary.My.MySettings.MyConnectionString.Can the same principle I showed above be somehow applied to this second connection string?

Winforms - .net Connection Entity Framework Connection String Security?
Sep 3, 2011I understand the possibilities for encrypting a connection string in .net v4. I have a win forms application that will be used by multiple people on different machines. I understand that I need to protect the connection string at time of the app being first run on the target machine. However I am concerned that for a period of time my connection string will be unencrypted. I am looking for advice in how to deploy my app with the connection string already encrypted or encrypted during installation. encrypting the connection string in a secure way?
View 1 RepliesInvalid Connection String When Modifying Tableadapter Connection?
Jan 19, 2011I'm developing an app in vb.net (visual studio 2008). I have a Teradata back-end that will be supporting multiple users in a production environment. I need to use variables in the connection string as the user/pass will be changed every 3 months.
For the gist of the application:
In it's most basic form - I have a search form which works correctly - it pulls results into a listbox and the user then double clicks the list box which will then open a form that is bound via table adapter to the back-end table (Teradata). My connection string is fine everywhere in the application. My problem is using a modified connection string for the "fill" function of the table adapter once the form is opened.
I'm using the code below for the on-load event and keep getting an "invalid connection string" - again, the connection string works fine everywhere else in the app, and the variables etc... are working correctly.
Private Sub adaptertest_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

Creating An SQL DB Connection During Runtime?
Nov 22, 2009Needing pointed in the right direction. I am fooling around with data sources and connections per homework and what I'm looking for is creating an SQL DB connection during runtime. I know that you can add a data source in design by going through the Wizard but what if one would want to create the connection, adapter, and dataset during runtime? Where would you start?
I have cruzed the net looking for some form of a tutorial to just get me started, I don't need it all completely outlined but I need to know where and how to start and what I need to declare the connection, string, and dataset as. I have seen a lot of information using VB6 but nothing that I come across seems to work.
My basic questions are:Do I have to create a seperate class for the database connection?How do I delcare the nuts and bolts of the connection,adapter, and dataset?If a seperate class isn't required then where is the most realistic place these items would be created?

Pointer - Rewrite A C++ Library
Jan 4, 2012I'm trying to rewrite a C++ library. But I have an issue. I'm not extremely pointer-savvy. In the C++ class there is a std::vector that holds unsigned int pointers (vector<unsigned int*>), and the int pointer just points to an array of integer data.
Here is the C++ code I'm a bit unsure about:
unsigned int* relocation = m_relocations.front();
m_relocations.pop();
unsigned int* reloc = *(unsigned int **)relocation;
