Issues Under Non-Administrator Accounts

[User (Old forums)]

#19511 |

I compiled the sample application and tried compressing files with it. The sample application compresses and decompresses files normally under an administrator account, but throws an error under the other accounts. Normally, everything is fine as I program under my normal user account, but Xceed Streaming Compression for .NET just gives strange behavior. I spent a lot of time looking at my own code to see if I did anything wrong, until I came up with the idea of using your sample application as a test.

Sample Used: \Xceed Components\Xceed Streaming Compression for .NET 1.0\Samples\CSharp\Manager
Compression Options: ZLib/Deflate64/Maximum
The sample gives “An unexpected internal failure occurred in the compression engine.”

I’m using 1.0

Can you tell us what is the InnerException of this exception?

This is the error text I got after removing all the TRY blocks

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 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.
