Debugging COM server using CDB/WinDbg combination

By

This actually applies to any application but most applicable for COM/DCOM servers and Windows services. 

For example, to debug Notepad application remotely or on another session add the following to the registry on the target computer. 

c:\> reg.exe ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\Notepad.exe" /v debugger /t REG_SZ /d  "\"C:\Program Files (x86)\Windows Kits\10\Debuggers\x86\cdb.exe\" -server tcp:port=5500 -g -G" /f

 When Notepad.exe is run it will automatically be attached to a debugger (cdb). To connect to the cdb session using WinDbg, do 

c:\> "C:\Program Files (x86)\Windows Kits\10\Debuggers\x86\windbg.exe" -remote tcp:server=localhost,port=5500

~ts

The following add-ins could not be started MonoDevelop.GnomePlatform

By
Installing MonoDevelop in OpenSUSE 12.2 from its repository was very easy. When running it for the first time though I got the message: The following add-ins could not be started: The root of the trace shows MonoDevelop.GnomePlatform,2.8 A quick search shows that MonoDevelop depends on libgnomeui . This should have been part of dependencies when installing the application but well.... Below is the screen shot of the error message. References: http://software.1713.n2.nabble.com/MonoDevelop-and-openSUSE-12-1-td7462957.html [2013/04/09] - Same issue observed in OpenSUSE 12.3 and also the same fix. [2014/11/02] - Same issue observed in OpenSUSE 13.3, mondevelop 3.0.6 and the same fix.

Error! Could not locate dkms.conf file install VirtualBox 4.1.8 on Ubuntu 11.10

By
Tried to update my Ubuntu host today and it did pickup that new version of VirtualBox is available (4.1.8). All other packages installed properly except that VirtualBox installation was complaining about missing dkms.conf file, see error message below. $: sudo /etc/init.d/vboxdrv setup * Stopping VirtualBox kernel modules [ OK ] * Uninstalling old VirtualBox DKMS kernel modules Error! Could not locate dkms.conf file. File: does not exist. [ OK ] * Trying to register the VirtualBox kernel modules using DKMS [ OK ] * Starting VirtualBox kernel modules [ OK ] Though it looks like installation was fine but I am concerned about its effects to VirtualBox functionality. To fix this, do: $: cd /var/lib/dkms/vboxhost $: sudo rm -r 4.1.4 $: sudo /etc/init.d/vboxdrv setup Of course you have to re
