My overall goal is pulling different machine information for remote machines.

I have several user controls all pull different information. One user controls gets the information (machine name) and I need the others user controls to see it.

The way I have it set up is I have a text box and a button and on button click I would like the application to pull the machine information.

I have read about global variables, but I am new to programming.
I have tried:

VB

Dim comphost as string
comphost = machinename.text

I think I am on the right path, but I need help.

Solution 1

It all depends on what you want to do with the variable. What will the UserControls do with this information ?

In answer to your comment. You should create a public property in your main form, something like this:-

VB

Public Property CompHost() As String
Get
    return compHost
End Get
Set(ByVal Value As String)
    compHost = Value
End Set
End Property

then in your user control you create a constructor that takes a string as a parameter and pass in this property when you open it, something like this:-

Public

VB

Class myUserControl

    Public Sub myUserControl(compHost As String)
        'do something with compHost
    End Sub

End Class

Maybe this will give you a better idea. Good luck!

all i want it to do is use the machine name that goes in the text box so the other user controls can use it as well. I have one user control that pulls hard drive info and another that pulls networking infor and all they need is the machine name. If you can help that would be great.

Then you should create a public property on your main form, that gets passed to the user controls through their constructor, as and when they get created.

sorry for such a late response but i have tried that and i m still having issues. I have the text box called comphost, and the usercontrol it sits in is call uctrl_header. I dont understand how i tell the code above how to pull the text from the text for the comphost. Forgive me i am new to visual basic. thanks for the help
