Question

When I executed the following code piece it fails with error code 317. How can solve the issue? We are using Unicode Character Set for the project

  char* pszMessgeBuffer = NULL;
  FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | 
        FORMAT_MESSAGE_FROM_SYSTEM | 
        FORMAT_MESSAGE_IGNORE_INSERTS,
        NULL,
        dwErrorId,
        0, // Default language
        (LPTSTR) &pszMessgeBuffer,
        0,
        NULL )

Answer 1

Using the error code lookup tool from Visual Studio, 317 is described as

The system cannot find message text
for message number 0x%1 in the message
file for %2.

This means that a message description does not exist in the system for the previous error code. The MSDN documentation for FormatMessage with flag FORMAT_MESSAGE_FROM_SYSTEM states that:

Not all Windows Embedded CE–based
devices will contain the system
message-table resources. This is a
selectable part of the Windows
Embedded CE operating system and is
often removed to conserve space.
