I have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.
But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.
How to make Dynamic Connection string for VB.Net 2008 & Sql Server 2005 database
View 1 RepliesI have a gridview which I databind to EntityModel This typically looks like
something a
something b
companyID
on Login I get and set the compnay which has the ID so what in essence I want to do is on databind set the Where clause of data source to what the server side paramter for company ID is. I am sure this is super simple but it is driving me nuts
Ok I have a question about connection string in vb.net. Im using the string [Code] but here I am specifying the serverName by its name, now if I deploy my application and send it to another person to use it I see that server name is changing according to the name of the computer. Is there any way where by I can make my application to detect itself the Name of the server present in that computer and use it in connection string?

I am looking to make a data connection with a network server(sql server 2005). When I run the data source configuration wizard, it allows me only to pick a local database file. I want to use a connection string like this "Data Source=SQLSERVER;Initial Catalog=mydb;User Id=username;Password=password;" I know I can do that programmatically. But I would like to know whether I can do that using the data source wizard so that I will be able to use Bindingsources and tableadapters.

I have an existing project written in VB.NET using Visual Studio 2005 communicating to a SQL Server 2005 database. The database was migrated to a sql server 2008 r2 on a different physical server so the dataset's server name needs to be updated. I do not have access to the database anymore. is there a way to just update the server name without invoking the dataset wizard and requiring a connection to the database?
UPDATE: I tried to created a new project with just a button with the command calling the following subroutine to test the connection from a windows app to the sql server database. here is the sub:

I am able to created a system dsn on the same server with the same credentials and test the connection successfully.
Which technology should I use for data access layer?What's the best way of connecting to a dynamic data source and binding the result to a grid?I'm writing a little web app that user can define connection string and table name (MS Sql Server) and the program will display values in that table inside a grid.We must use datasets (because of dynamic data source) and generate the query as a text command ("Select * From " + TableName).We don't have a model (data source is defined by user at run time) so we can not use EF.

[i][b]I have always developed apps for desktops with an access database on one server for one company or sql server. I had one connection string. Now I am in a situation with multiple clients using my software on their own server. This means different connection strings can anyone suggest an efficient way to do this without changing connection strings for each server throughout the application?[/b][/i]
View 1 Repliesi have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?

I re-wrote this to make it more readable. If you want to skip right to the chase, look at the ALL CAPS comments in the code blocks. All necessary code has been included for debugging. I've searched multiple forums (including ASP.NET), and the MSDN library and cannot fix this >.<

View 7 RepliesI have an application I have developed which works great on individual PC's. However I've had some interest from a few customers that asked if I have a network version for site licencing.If my app did not save any data or write any reg entries, this might have been ok. But it does to the local computer. I also built in my own copy protection and trial function that stores data in the registry on the local computer.What would I need to do to enable my application to run on a server/network share, so that the only a serial number needed is for the server?

View 4 RepliesI have installed sql server 2005 in my machine which is installed vb.net 2008. I want my machine to distribute the database to the clients and make it as server.I don't have that much knowledge of how to overcome this issue as i am awfully naive about it.Let me start it here:I have got an application in vb.net...at first i was using ms access database 2007. then decided to switch on to the sql server since i want to distribute the database to the clients who are going to use my application.When i installed the sql server, i imported my access db files onto sql server database. i enabled tcp/ip as enable in the sql server network Configuration. i want use sql server windows authentication as my default user account of my system for the sake to simplify the issue.
Hence, i connected the sql server into the vb.net through the "add new data source".am done with that...the problem is how do i assign the connection string to the vb.net? Or how do i include a connection string in vb.net which tells every other computer that the database data source is in my computer so that every computer can automatically check it in the network.Where exactly shall i put the connection string...as far as my knowledge is concerned for access database, you can easily identify your connection string in project /properties/settings...it goes here and you put your database in any where.And what is the best connection string do i need for sql server 2005..computers are running windows xp.
