Hi,

Im using a WebBrowser control within VB6...I have back and forward buttons just like in IE..however, i want to disable the back, or forward buttons within the menu if the WebBrowsers history is empty...in javascript it is obviously history.length ....is there anyway i can either return this value to my vb app, or use my own VB call to get the windows history????

Also, anyone any idea how to disable an item in a VB 6 menu, i dont see that the menu has any object name i can refer to???

Thanks

From MS:

"The WebBrowser control supports a CommandStateChange event, which is fired whenever the Forward or Back buttons need to be enabled or disabled. "

http://support.microsoft.com/default.aspx?scid=kb;EN-US;163282

' A Visual Basic application can also implement this
' functionality in this manner:  

Private Sub WebBrowser_CommandStateChange(ByVal Command As Long,ByVal Enable As Boolean)

       Select Case Command
           Case CSC_NAVIGATEBACK
               Back.Enabled = Enable
           Case CSC_NAVIGATEFORWARD
               Forward.Enabled = Enable
       End Select

End Sub

oops...

Here are the constants:

Private Const CSC_NAVIGATEFORWARD As Long = 1
Private Const CSC_NAVIGATEBACK As Long = 2

Hi Erick,

That seems to work great, however what does Back.Enabled and Forward.Enabled refer to .... i just ran this code and it crashes due to the fact that there are no objects called Back or Forward in my App...

Should this refer to the menu item name??

Right, replace Back.Enabled to [the name of your back button].enabled
