Re: vb.net 08 Reading data from multiple reg keys
 

C# IS .net. It's just a C style usage of it.

    Public Function GetInstalled()

        Dim uninstallKey As String

        Dim rk As RegistryKey

        Dim sk As RegistryKey

        Dim skName As String

        Dim sublist As New ArrayList



        uninstallKey = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"



        rk = Registry.LocalMachine.OpenSubKey(uninstallKey, True)



        For Each skName In rk.GetSubKeyNames()

            sk = rk.OpenSubKey(skName)

            sublist.Add(sk.GetValue("DisplayName"))

        Next skName



        Return sublist

    End Function

Try Comatose's code, and tell what you get?

Re: vb.net 08 Reading data from multiple reg keys
 

okay that code returns no errors but how do i display the display names it finds in a combo or text box?

Re: vb.net 08 Reading data from multiple reg keys
 

Drag a comboBox and drop it into your form
Edit Comatose's code

For Each skName In rk.GetSubKeyNames()            

sk = rk.OpenSubKey(skName)            

comboBox1.Items.Add(sk.GetValue("DisplayName"))        

Next skName

Re: vb.net 08 Reading data from multiple reg keys
 

okay, but when i run the code nothing gets returned in the box.

could it be the displayname part as if you go to the registry and pick a sub key, you will see displayname. When you click on display name the key is shown but its the 2nd part under value data i need.

as if i want a particular key for the processor i use

Dim myCPUDescription As String = My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0", "ProcessorNameString", "No CPU Found").ToString.Trim

and that returns the value data under the key

Re: vb.net 08 Reading data from multiple reg keys
 

You shouldn't modify the function. The concept of a function, is that you shouldn't make them interact with the form. The idea of a function is that a function can be modular.... what if in the future, you decide to change it from a combobox, to a listbox... or save it to a file. Then you have to modify the function that actually GETS the display names of the registry keys. The purpose of a function is abstraction.... what this function does, is get the list of items in the registry (their display values) and returns them to the calling procedure. So for example, if you have a button, you would do:

dim something as new arraylist

something = GetInstalled()

for I = 0 to something.count 

     msgbox something(i)

next I

It might have to be for I = 0 to something.count -1

I know Comatose, but it was my last chance to get him solve his problem!!!

Re: vb.net 08 Reading data from multiple reg keys
 

I know why you did it, and were absolutely right... I just wanted to make the distinction for him, so that he understands the concepts. I would have suggested the same code mod you did ;)

Re: vb.net 08 Reading data from multiple reg keys
 

ah right so the function is left alone so if i add a button i would now need to call that function from the code under the button.

Re: vb.net 08 Reading data from multiple reg keys
 

Right, it returns an arraylist. So you would call it from the button, then assign the return value to an arraylist, and loop through it.

dim something as new arraylist

something = GetInstalled()

for I = 0 to something.count 

     msgbox something(i)

next I
