Shootin' Trouble with Application Launcher/Explorer
Novell Cool Solutions: Tip
Digg This -
Posted: 4 May 1999
Did you know that you have some extremely useful information just a few clicks from the Application Launcher and Application Explorer icons on your desktop? True. If you run into a problem and call Novell Technical Services, you may need to supply the version of the program you're running or of the files that make up a program you're running.
Maybe you've read one of our TIDs and need to find out if the version of a DLL you're running matches the version of a DLL that fixes a specific problem your system is having. Or, what if you're the network administrator and are upgrading the Application Launcher? If the server and workstations are running the same version of the software, you can upgrade at the server only. That could save you some time and effort.
Get Information about File Locations (Paths) and Versions
In any of the situations described above, you'd need to find out about paths and file versions. Here's how you do it:
- From Application Launcher or the Application Explorer window, select Help > About > More.
- Read the information about filenames, paths, and versions in use by Application Launcher.
You can also right-click the Application Explorer icon on the desktop and select Properties > More. This location shows the path and version number of specific files.
Figure 1 shows the More About dialog box for Application Launcher. Notice the file pathnames and date stamps (22.214.171.124 means September 17, 1998) for the different kinds of files.
To find out whether you have the correct version of a file or application, compare the version number of your file or application to the date on the recommended file or application version. If the date of your version matches the date on the recommended version, you're in business.
Get Information about the State of Currently Running Applications
This procedure is available only for Application Launcher, not Application Explorer.
- Press and hold the Shift key when opening the About box (Help > About).
The Applications Running field gives the number of currently running Application Launcher-delivered applications for the current user. The Resources In Use field reports the number of resources (a server connection, a drive letter, or a printer port) in use.
- From the Debug Information Box, click Applications to display debug information about the applications running. Highlight an application and click Select to see the resources for that application. Or, click Resources to display all resource information for applications currently running. You can also click Environment to read information about any environment variables in use for Application Launcher-delivered applications.
Get Tree-Specific Information
At some point you may need to find tree-specific information for the currently authenticated user. Follow these steps to get to that information:
- From Application Launcher or the Application Explorer window, choose Help > About >
- While holding down Ctrl+Alt, double-click an Application object in the Login Information list.
The following table explains the information you will find in the User Information dialog box:
|Information in This Box||Answers This Question|
|Container levels||How many levels up the NDS tree does Application
Launcher/Explorer look for applications?
This number is specified on the Launcher Configuration property page of the User or container object to which the Application object is associated.
|Supports application objects||Are Application objects supported in this tree? Does this tree have the necessary schema extensions to support Application objects?|
|Schema supported||What are the version numbers of supported schemas?|
|Rights to group membership list||What rights does the user have to his or her group membership attribute on his or her User object?|
|Monitored connection||Don't worry about this little tidbit of information. It's not used any more.|
|Save folders||Will personal folders be saved at exit if they've been changed?|
|NRD support||Is the NetWare® Registry Database (NRD) supported? What
is the path to the NRD.DLL? If "No," NRD.DLL was not
(NRDDLL16.DLL, NRDDLL95.DLL, NRDDLLNT.DLL).
If "Yes, No," NRD.DLL was found but the tree does not have the NRD extensions or the user does not have rights to the NRD attributes on his or her User object. If "Yes, Yes," NRD.DLL was found and is ready to go.
|E-mail attribute||Which attribute on the User object is used for the E-mail address in the Contacts page?|
|Login DLL version||What is the version and path to login DLL (used for script processing)?|
|Read groups for applications||Does the User object look to groups to which applications
might have been associated?
If a Group object has been associated with Application objects, users who are members of that Group can run Application objects by virtue of their membership. While this is a convenient way of indirectly associating users with applications, it can also decrease performance. If you want to increase performance, set this option to No in the Launcher Configuration property page of a User, Organizational Unit, Organization, or Country object.
