Ordner öffnen und Windows-Lautstärke ändern

Hallo,
die Frage is zwar sowas von simpel aber ich musses zum ersten mal machen un hab keine Ahnung wie es funktioniert. Ich will einfach nur über einen CommandButton einen Ordner öffnen.

Ich dachte immer es geht mit Shell("C:/") oder so. Aber hab gerade bemerkt dasses so nicht geht:D
Hab schon im Internet geguckt un 10000 Sachen gefunden, aber nicht den einfachen Befehl einen Ordner zu öffnen:D.
Es is ja auch schon spät :depp:

Wäre nett wenn mir mal einer sagen kann wie es funktioniert..;)
Danke schonmal
mfg fexs

Edit:
Achso un wo ich grad schon am dumme Fragen stellen bin:
Weiß jemand mit welchem Befehl man "Ton Aus/Ein" hinbekommen könnte??
Bis dann
 
Der Befehl
Code: 
explorer /root,c:
öffnet dir den explorer im Verzeichnis c:\ (in der Konsole)

Also dürfte es in VB dann mit
Code: 
Shell("explorer /root,c:")
funktionieren...
 
Hier gibt es noch eine offen Frage: VB6 oder VB.NET?

Eine weitere Frage: Die Antworten öffnen alle einen Explorer.
In einem Programm kann man damit reichlich wenig anfangen.

Wills Du einen Explorer, oder einen Dateidialog aus einer Anwendung heraus?
 
Unter VB.NET finde ich diese Loesung optimal:

Code: 
System.Diagnostics.Process.Start("C:\")

Unter VB6 (was du hoffentlich nicht verwendest), kannste den Shell() mist probieren.
 
Hallo,
das was Zerd gesagt hat wollte ich nur wissen;)
Danke:)

Aber hat zufällig auch einer ne Ahnung wie das mit dem Ton aus/ Ton ein geht?^^
Also gibts en Code dafür oder liegt vllt irgendwo im System ne .exe die bei klick den Ton ausmacht?:D
Oder kann man sone .exe downloaden und ann irgendwie ausfürn?
Könnte ja sein..
Bis dann
