Application Manifest Schema:

Posted by senthil | 12:41:00 AM | , | 0 comments »

Application manifests are not new to the Windows Vista release. Manifests were used in Windows XP to help application developers identify such things as which versions of DLLs the application was tested with. Providing the execution level is an extension to that existing application manifest schema. The Windows Vista application manifest has been enhanced with attributes that permit developers to mark their applications with a requested execution level. The following is the format for this:

<requestedExecutionLevel
level="asInvoker|highestAvailable|requireAdministrator"
uiAccess="true|false"/>
Your application will prompt for elevation if the user is an administrator and UAC is enabled
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
  <security>
   <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
    <!-- UAC Manifest Options
      If you want to change the Windows User Account Control level replace the 
      requestedExecutionLevel node with one of the following.

    <requestedExecutionLevel level="asInvoker" uiAccess="false" />
    <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
    <requestedExecutionLevel level="highestAvailable" uiAccess="false" />

      Specifying requestedExecutionLevel node will disable file and registry virtualization.
      If you want to utilize File and Registry Virtualization for backward 
      compatibility then delete the requestedExecutionLevel node.
    -->
    <requestedExecutionLevel level="highestAvailable" uiAccess="false" />
   </requestedPrivileges>
  </security>
 </trustInfo>
