JIT Debugger

Hi,

I've been trying to get JIT Debugger to work again. I had no evident problems with it until I installed a HP Deskjet 5610 All-In-One printer. The software for the printer s*cks big time and when I reboot, 1/2 the time I receive a message that states that I need to place the HP CD in my CD ROM Drive in order to install TrayApp and Document Viewer. I've done this at least 10 times. I contacted HP several times but their instructions didn't help. If I don't get the CD in my CD ROM Drive fast enough, I receive a message that's very long and it freezes my computer. The end of the message says:

************** Exception Text **************
System.NullReferenceException: Object reference not set to an instance of an object. at HP.CUE.Video.PlaybackControl.UpdateProgressBar()

This message, I believe, is the cause of all my problems but I don't know the cure.

Then it goes on to say:

To enable just in time (JIT) debugging, the config file for this application or machine (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

I'm surmising that if I enable JIT debugging, I'll no longer have the TrayApp and DocumentViewer problems, but I don't know how to do what it says to do.

I searched through the Microsoft help pages and found this

JIT Debugging Setup
To use JIT debugging, you must configure your platform to support KITL services, and then package the correct debugging libraries into the OS kernel. You must also enable debugger support in the kernel. You can use one of the following methods to enable debugger support:

Include the static library file KdStub in the kernel at build time. In the MODULES section of the Project.bib file, include Kd.dll. For more information about the MODULES section, see MODULES Section.
Dynamically load KdStub. In the FILES section of the Project.bib file, include Kd.dll so that you can dynamically load KdStub later. For more information about the FILES section, see FILES Section.
Typically, you include KdStub in the kernel at build time for a debug version of an OS, often during the early stages of platform development. During the final phase of platform development, when working with a release build, you dynamically load KdStub to provide JIT debugging.

If you include Kd.dll in the MODULES section, JIT debugging is automatically enabled if a second chance exception or a debug break occurs on the target device. If Kd.dll is in the FILES section, JIT debugging does not start until you run Loaddbg.exe to load Kd.dll dynamically.

When JIT debugging is not enabled, exceptions are not handled appropriately and unhandled second-chance exceptions cause the application to terminate.

To use the debugger for JIT debugging, you must allow Platform Builder to connect to the target device, because when the debugger activates, it requires a connection for the debug output. From the Target menu, choose Configure Remote Connection, choose the Settings tab, verify that the Connect to Device check box is selected, and then choose OK.

The final release of an OS should not contain the debug libraries. Removal of the debug libraries ensures that the proper response to a second-chance exception occurs: the application terminates but the OS continues to function.

By loading KdStub, you use the kernel debugger in Platform Builder for JIT debugging. As an alternative, you can use a device-side JIT debugger. To use a device-side JIT debugger, include a JIT debugger such as UsrExceptDmp.exe in the MODULES section of the Project.bib file. In the HKEY_LOCAL_MACHINE\Debug registry key on the target device, register the JIT debugger by adding the name of the debugger to a JITDebugger registry entry. Reset the target device after you add this value to the registry. If you use a device-side JIT debugger, when there is a second chance exception or a debug break, the target device does not connect the Platform Builder kernel debugger but instead runs the JIT debugger included in the MODULES section.

Since I didn't have any idea what the above meant or how to do it, I tried to take the easy way out. I went into Tools -> Internet Options -> Advanced Tab -> uncheck "Disable Script Debugging." However, I keep getting messages on most of the pages that I open that ask me if I wanted to debug a script. I need to click on "Yes" a number of times for each page that causes me to receive the message and most of them end with "permission denied."

In several messages, a reference was made to my Host file. About a year ago, my Host file "disappeared" and it was replaced with Hoster. I don't rememeber the exact wording of the message but the jist of it was that my Host file isn't the original file and it wants the original file.

Can anyone translate the Chinese for me and tell me where I have to go in my pc, how I can get there, what setting needs to be changed, how it needs to be changed and what it needs to be changed to? The instructions seem more like programming than basic software settings and the instructions must be written for programmers.

Maybe you can help me solve this problem first . . . I mentioned it in my original post:

How can I get the debugger to work automatically? Machine Debug Manager is set to Start/Automatic in Services but JIT Debugger is not included in Services.
