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.
I am a brand new user of MS Visual Basic 2005 Express and MS SQL Server 2005 Express. I have familiarized myself with both programs but have one extremely frustrating problem. Once I open SQL Server, I can not establish a database connection from Visual Basic using the Visual Basic Data Source Configuration Wizard (even if I close SQL Server). If I reboot and open Visual Basic first, I can then connect using the Visual Basic Data Source Configuration Wizard. But then I can not switch to SQL Server and open the database (even if I close Visual Basic). Again, I must reboot to open the database in SQL Server.I suspect there is a setting somewhere that needs to be changed, but I can not find it?

I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.

View 2 RepliesI have several sets of similar objects (labels, progress bars) on a form in Visual Basic 2010 on Windows. In my code, I have collections that contain data, which needs to be pushed into the value/text property of each.
I would like to get a solution similar to PHP in that I can assign values somewhat like:
For ID as Integer from 0 to count(collectionExample)
lblExample{ID}.Text=collectionExample(variableID)
...and as such to loop through so each of the different lblExample's were updated to their corresponding value.
The issue I have come to is that I cannot seem to reference an object on the form using a variable. I have also tried using something like
CallByName("lblExample" + variableID, "Text", CallType.Set, exampleCollection(variableID))... however I still can't combine the string and variable to reference the object.
Any solutions on referring to objects in VB2010 by combining a string prefix and a variable string identifier, similar to PHP's $variable{$variable} approach?

im trying to add a new data source to my visual studio 2010 project. As it stands my project consists of a few windows forms. I plan on making it access a database (made in access, unless this is a problem), and be able to perform pre-set queries, search/sort, and basic delete,add,edit functions. I will hopefully be later adding the function to print reports according to the database entries.However, the problem i am having is that when i go on to data sources, and click add new source, the following happens:3, it asks me which connection i will be using, i click new connection, then in the new connection dialog i choose the following : Microsoft Access Database File (OLE DB), then i browse for the database i made in the 'database file name' box, Then i delete the default username in the log in to database bit, as my database has no protection.
