    <p>Say I've got the following variables:</p> <pre><code>Public Shared x As String = "100" Public Shared y As String = "text" Public Shared z As String = "something" </code></pre> <p>And I got a function:</p> <pre><code>Function giveVar(ByVal varName As String) As String Return varName End Function </code></pre> <p>But this doesn't do what I want, naturally. What I want is that my function <code>giveVar</code> returns the value of the variable that holds <code>giveVar</code>. For example I call <code>giveVar("x")</code> I want my function to return <code>"100"</code>. </p> <p>Of course this can be done by a <code>Select Case</code> but thats not what I like to do. Does anyone has any suggestion? Is it even possible to call a value based on a string?</p> <p>[edit:]</p> <pre><code>Namespace i18n public NotInheritable Class Settings Public Shared LanguageCode As String Public Shared HideAllLocalizedText As Boolean End Class Public NotInheritable Class i18n Private Sub New() End Sub Public Shared Function t(ByVal varName As String) As String Select Case Settings.LanguageCode Case "en" Return en(varName) Case Else Return nl(varName) End Select End Function Private Shared Function en(ByVal varName As String) As String Dim ASP_0344 As String = "Cancel" Dim ASP_0807 As String = "Click" Dim ASP_0808 As String = "here" Dim ASP_0812 As String = "Welcome at the login screen..." ' These are examples there is a whole bigger list Return CallByName(Me, varName, vbGet) End Function Private Shared Function nl(ByVal varName As String) As String Dim ASP_0344 As String = "Annuleren" Dim ASP_0807 As String = "Klik" Dim ASP_0808 As String = "hier" Dim ASP_0812 As String = "Welkom op het inlogscherm..." Return CallByName(Me, varName, vbGet) End Function End Class End Namespace </code></pre> <p>I think this works so far, BUT I get the following error on the <code>CallByName(Me, varName, vbGet)</code> at the <code>Me</code> : <code>"me is only valid within an instance method"</code></p>

    1. COI would question why? To actually do what you want you will need to use reflection and offset any compile exceptions to runtime.

    2. COAre you limiting this to string members only? What if the variable name specified is of a different type?

    3. COIt is only for strings. It's a way to make a 'generic' multilanguage possible based on the users preference. The way I want to do it this way is because the variables are already defined for all languages. I'll post what i did so far in the OP.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
