I am trying to figure out how to change the class name on a textbox from "WindowsForms10.EDIT.app.0.bf7d44" to something like "textbox1". Right now the textbox has no caption so i can not just use vbnullstring for the class since i have no caption for the textbox.
Is there any settings in VB.net 2008 that will allow me to change class names?

I want to change my class library's settings from an another program. For this, I've made a Public property in my class library. It worked right. But this is not my question. I wonder this is a right method? Can I access a class library's settings (My Namespace) from other project directly?

If this were a Windows forms project I have used the System.Drawing.Printing namespace to accomplish my goal. However, I cannot import this namespace into a Class library.Overall here is what I am trying to do:I am trying to set the default printer using this namespace on both Windows XP and Windows 7 workstations. I am using Visual Basic 2008. My ultimate goal is to create a COM dll which is accessed from an older VBA program. The COM Dll will set the default printer to a new printer. Execution will return to the VBA program and it will print a Crystal Report. When the Crystal report is finished the VBA code will use the COM Dll one last time to set the default printer back to the original default Printer.But as I mentioned I cannot import the namespace I want to use into a Class library. Can someone give me some guidance on how to either import the namespace into a Class Library or how to determine the Default printer name and to set the Default printer to a different value?
Update: I was able to add the Imports Namespace after I added a reference to the correct DLL in Project Properties. My project is targeted at the 3.5 .Net Framework. The System.Drawing.Printing DLL is not in the 3.5 framework. That DLL is in the 2.0.50727 framework. After browsing and Adding that DLL, everything is working fine.BUT this leads to a new question. How would determining the default Printer be accomplished in the 3.5 .Net framework?Secondly, am I asking for trouble having a project target the 3.5 framework AND including a 2.0.50727 component in the same project?
I am attempting to move a highly referenced class from one namespace to another. Simply moving the file into the new project which has a different root namespace results in over 1100 errors throughout my solution.Some references to the class involve fully qualified namescape referencing and others involve the importing of the namespace.
I have tried using a refactoring tool (Refactor Pro) to rename the namespace, in the hope all references to the class would change, but this resulted in the aforementioned problem.Anyone have ideas of how to tackle this challenge without needing to drill into every file manually and changing the fully qualified namespace or importing the new one if it doesn't exist already?

In my earlier project I was able to change the connection string during the app settings loaded event and it was successfully. When I try to do the same for a code library project, I am not getting the system.configuration.connectionstringsettings to work. Could you please tell if there is a work around for this, or else it is always better to write the sql code instead of depending on the adapters etc.

View 1 RepliesYou 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?
