For example, consider this C# call to the DeleteFile Win32 function: //attempt to delete a file that doesn't exist DeleteFile("TestFileNotThere"); If the call fails (as it should in this case), we can call the Marshal.GetLastWin32Error method to retrieve the Win32 error code like this: Console.WriteLine("DeleteFile last error code: {0}", Marshal.GetLastWin32Error()); However, this will only work if we include the SetLastError field in the DllImport function declaration like this: //save the last error, and use the wide version [DllImport("kernel32.DLL", CharSet = CharSet.Unicode, SetLastError = true)] public static extern bool DeleteFile(string fileName); When we execute DeleteFile for a nonexistent file, we see these results: DeleteFile last error code: 2 This is the correct error code since 2 is defined as ERROR_FILE_NOT_FOUND in the Win32 documentation. Since we set SetLastError to true, PInvoke saved the value from the GetLastError API function, making it available to us via Marshal.GetLastWin32Error. If we declare the function like this, without the SetLastError field, we will be unable to get a meaningful error code: //do not save the error code [DllImport("kernel32.DLL", CharSet=CharSet.Unicode)] public static extern bool DeleteFile(string fileName); Calling Marshal.GetLastWin32Error in this case will give us an unpredictable result. We ll get a number returned, but it will not be the correct error code. The reason is that we have not instructed PInvoke to save the last error code from the Win32 call.

Words are stored as a series of allophones in an array, so to make it easier to read the array we'll define a memorable token for the "Word Pause" value that is appended after each word. The SpeakJet has six different pauses available, but the most commonly used pause between words is allophone 6 which has a duration of 90 milliseconds. By defining WP as the value 6 we can simply put WP into the word array as if it's a single byte, and not have to remember that allophone 6 is a magic value. #define WP 6 Next, we'll set up an array called message to hold the allophones for the words we want to speak. By breaking it up visually and embedding comments within each line we can make the array much easier to read. Finally, tacking a WP value onto the end of each word inserts allophone 6, the word pause. Working with the message array this way makes it relatively simple to copy and paste different words into place to make up your own sentences, as follows: byte /* /* /* /* /* }; message[] = hello */ my */ name */ is */ arduino */ { 183, 140, 141, 8, 152, 007, 155, 154, 129, 148, 159, WP, 140, 167, 175, 146, 164, WP, WP, WP, WP, 147, 128, 141, 164, WP

Once you have obtained the last Win32 error code, you can use the Win32Exception class to look up a descriptive message for the error. It is not necessary to use PInvoke to call the Win32 FormatMessage function to look up the message. The constructor for this exception takes the error code that you retrieved like this: //turn the win32 error into an exception throw new Win32Exception(lastError); When you throw this exception, any code that catches it will have access to a descriptive message for the Win32 error. We can rewrite the preceding code to not only retrieve the error code, but also throw the exception and show the results:

While a manager may enter an original estimate based on a project plan, the actual estimate must be owned by the developer who s actually doing the work You can t get a 10-hour feature done in 5 hours simply by chopping the estimate in half Keep all the work that has to be done in a single system (such as FogBugz!) If there s a place to estimate every task, developers will be less likely to pad estimates to include time for off the books work When you run into a new task that s not on the project, take the time to enter a case for it After you ve been entering estimates for a while, take the time to review the original and final estimates on your own closed cases to look for patterns.

Later the program will need to know the length of the message array, so rather than count the values manually and have to update it every time the message is changed we'll instead have the program count the array elements and store it for future reference.

try { //attempt to delete a file that doesn't exist DeleteFile("TestFileNotThere"); //returns system error code 2: ERROR_FILE_NOT_FOUND //"The system cannot find the file specified" int lastError = Marshal.GetLastWin32Error(); Console.WriteLine("DeleteFile last error code: {0}", lastError); //turn the win32 error into an exception throw new Win32Exception(lastError); } catch(Win32Exception e) { Console.WriteLine( "DeleteFile last error message: {0}", e.Message); } Normally, you wouldn t throw and catch an exception like this within the same code block, but this works to demonstrate the results of the Win32Exception class. As an alternative, you can use one of the other constructors for this exception class that accept an error code. By doing this, you can simply construct a Win32Exception object and reference the Message property to obtain the description for the error.
