Win 10 Registry Key Value in Visual Basic

Question

Hi,

I am following this article to create and set the registry key in VB.
how-to-create-a-registry-key-and-set-its-value

It's creating keys as REG_SZ but I would like to create REG_DWORD (32-bit) value, is it possible?

You can see the samples from MSDN:

RegistryKey.SetValue Method

Answer 3

After reading the documentation for microsoft.win32.registry.setvalue
consider the following -

   Sub Main()  
       Try  
           Registry.CurrentUser.CreateSubKey("VBRegTest")  
           Registry.SetValue("HKEY_CURRENT_USER\VBRegTest", "String Value", "42")  
           Registry.SetValue("HKEY_CURRENT_USER\VBRegTest", "DWORD Value", 42)  
           'Following line unintentionally creates a string value because numeric value exceeds the capacity of 32 bit DWORD  
           Registry.SetValue("HKEY_CURRENT_USER\VBRegTest", "Unintended String Value", 3000000000)  
           'Following line creates a numeric 64 bit value  
           Registry.SetValue("HKEY_CURRENT_USER\VBRegTest", "QWORD Value", 3000000000, RegistryValueKind.QWord)  
           'Following line will throw an exception because the numeric value cannot fit into the explicitly specified DWORD data type  
           Registry.SetValue("HKEY_CURRENT_USER\VBRegTest", "QWORD Value", 3000000000, RegistryValueKind.DWord)  
       Catch ex As Exception  
           Console.WriteLine("Caught exception - {0}", ex.Message)  
       End Try  
     
   End Sub
