#10015 obsolete "Object reference not set to an instance of an object" - .NET Framework 4 Sam
Description

PC: Windows 7 Ultimate Virtual Machine: Windows XP Professional SP3

Hi,

I am trying to run an application that was developed using the .NET Framework 4. When I run it I receive the error "Object reference not set to an instance of an object" along with a detailed error log.

When I run this on my native OS I do not receive the error, and I have exactly the same versions of the .NET Framework installed.

After receiving advice from several sources they pointed out it's most likely the Virtual Machine software, i.e. Virtualbox.

The error log I get is:

See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

JIT Debugging To enable just-in-time (JIT) debugging, the .config file for this application or computer (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 computer rather than be handled by this dialog box.

#10018 obsolete No Directx on win 7 Van
Description

Ok I installed windows 7 on vbox 4.1.6 the newest version installed the guest additions but still get the same errors as before:

Which I run COH your the program just crashes for no real reason just crash.

When I run dxdiag I get no ddi version or do I get ny direct3d acceleration.

So I tried the safe mode thingie on win7 and it kill my directx to old version that is not supported my COH and then it trys to update with no help.

So I uninstall the guest additions to see if I could go back to the programs just crashing with no reason but that has gone too just says you need new version of directx. Even after reinstalling the guest additions.

I had to rebuild this VM to get the crashes to come back with the recommend installationof the wddm drivers and still no access to COH.

#10024 obsolete Leaving seamless mode causes X to hang Rainmaker
Description

This might be a "worksforme", but I'm trying to get seamless mode to work properly.

Entering seamless mode is no problem; everything works great. But when trying to leave seamless mode, the screen turns black. The only way to get back to a workable state, is to restart X.

Nothing interesting is shown in the logging.
