.NET Questions and Solutions

Symptoms
On a computer that is running Microsoft .NET Framework 1.1, when you use the StreamWriter.Flush() method or the StreamWriter.Close() method to access a file on a disk that has insufficient space, you receive the following exception error message:

System.IO.IOException: There is not enough space on the disk.After you free up space on the disk and then try to access the file again, you receive the following exception error message:

System.IO.IOException: The process cannot access the file “C:\outputTest.txt” because it is being used by another process.
Resolution
This problem occurs if the common language runtime (CLR) does not close the file handle after you receive the first exception error message. If the file handle does not close, you cannot access the file regardless of how much space is on the disk.

Symptoms
When a System.EnterpriseServices.TransactionProxyException exception is triggered during a transaction completion, it cannot be caught from other application domains. Instead, you receive a System.Runtime.Serialization.SerializationException exception that resembles the following:

Unhandled Exception: System.Runtime.Serialization.SerializationException: Type ‘System.EnterpriseServices.TransactionProxyException’ in Assembly ‘System.EnterpriseServices, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ is not marked as serializable.
Resolution
This problem occurs because the TransactionProxyException exception is not serialized, and then cannot be caught from another application domain.

Symptoms
The following floating-point exception error message might occur for queries that require a “merged” histogram:

Server: Msg 3628, Level 16, State 1, Line 2 A floating point exception occurred in the user process. Current transaction is canceled.
Resolution
A float overflow exception occurs in SQL Server when it combines the histograms for two indexes to handle the cardinality estimation for outer-join operators.

Symptoms
When you try to create a new user profile in Microsoft Commerce Server 2007, a new user profile may not be created.Additionally, you may receive the following exceptions in the Application event log.

Symptoms
When you run a Microsoft .NET Framework 2.0-based application, the application may experience an ArgumentNullException exception and may exit unexpectedly (crash).
Resolution
This problem occurs because the FileSystemWatcher class throws an unhandled ArgumentNullException exception. This exception is generated because a race condition occurs between events that raise loops and the StopRaisingEvents method.
