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.
View 6 RepliesChange Connection String At Runtime For Strongly Typed DataSet?
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:
Namespace
My
'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.
[Code] .....
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.
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?
VS 2010 Change Reference At Runtime
Nov 26, 2011Is there a way to change reference at runtime ? I am automating Word from VB.Net. I think what I have coded will be same for both Word2003 and Word2007. I used Word 12 Object Library reference(which is of Word2007). So, I want to know how to make it compatible with a machine installed with Office2003. That is, it will check the whether the machine has 2003 installed. If so, use that reference. Otherwise use 2007.

VS 2010 - Possible For User To Change Hotkey In Runtime?
Aug 28, 2011What I want to do is to make my application to SendMessage to another application. I can send message perfectly when i set keys.F1 or F2 etc in code but, I wonder, is it possible that user change this key in runtime? I was thinking about doing something like:
If combobox1.text = "F1" then
SendMessage(pHwid,WM_KEYDOWN, Keys.F1,0)
elseif combobox1.text = "F2" then
SendMessage(pHwid,WM_KEYDOWN, Keys.F2,0)
etc...
But I have 19 usable keys and alot of events with SendMessage function so code will be so big and there's possibility for slowing application. Is there anything that I can do, like...
Dim hKey as STRING? INTEGER? WHATEVER...
SendMessage(pHwid,WM_KEYDOWN, Keys.hKey,0)
?
VS 2010 : Change The Parent-child Relation In A Treeview Control At Runtime?
May 5, 2012I want to program a water supply pipeline network in a treeview control. It has five node (junctions). The parent-child relation is based on a parameter (say pressure). Initially, the node 1 is parent and its child nodes are 2 and 3. The node 3 has child nodes 4 and 5. At run time the pressure changes. Now, node 3 is parent and its child nodes are 1, 4 and 5. The node 1 has child node 2.

.net 3.5 - Change API Reference At Runtime?
Feb 15, 2010I'm writing an application for a device running Windows XP. There are 2 versions of the device and each version has its own API to communicate with the device's software. The application I'm writing needs to pull the same data from the API. My question is how to write a application that will detect at runtime which version of the device it is on and use the appropriate API.
I've created an interface containing all of the common methods and also classes for each device that implement the interface. Now I need to know how to activate the correct one at runtime.
Public Interface IAPI
Sub InitializeMachine()
Function GetActiveProgram() As String

Change Web Service URL At Runtime
Oct 27, 2009I have multiple urls to the same webservice, each with it's own "token". I need to switch from one url to another during runtime. I have planned to do this by storing my URLs inside a XML-file, and then read it, copy innertext of an element and overwrite the WS url in my app.config. My app reads and write to xml just fine, it is when I actually use a method from the webserivice proplems start to appear.

Change/recompile An .exe At Runtime?
Apr 24, 2011I am creating a program that will be sold as a subscription. I am trying to decide how to prevent users from passing the program to others without purchasing it. I was thinking that on the very first run, the program could pull the MAC address from the computer it is run on, and create a constant at run time. This constant is then hard wired into the program and is used for comparison every time the program is run thereafter. If the MAC address do not match, it is on a different computer.
How do I recompile my .exe to include a globally declared constant used for comparison? And how do I use this variable throughout my program?Or is there a simpler way to create my program to require Key Codes for renewal once per year?
