hi ,
yes its possible to call a custom web application / page onClick on ISV button ,
you need to specify the url in ISV Config ( i m assuming that you are using crm 4 as you havent mentioned)
A sample will look like this
<MenuBar>
<!-- Custom Menus - between the Goto Menu and the Help Menu -->
<CustomMenus>
<Menu Title="ISV">
<MenuItem Title="New Window" Url="http://www.microsoft.com" />
<MenuSpacer />
<!-- A horizontal drop down menu spacer -->
<SubMenu Title="ISV Tests">
<MenuItem Title="Modeless Dialog"
Url="http://www.microsoft.com" WinMode="2" />
<MenuSpacer />
<MenuItem Title="Modal Dialog"
Url="http://www.microsoft.com" WinMode="1" />
<MenuSpacer />
<MenuItem Title="Custom JavaScript"
JavaScript="alert('test');" />
</SubMenu>
</Menu>
</CustomMenus>
