GETLASTERRORTEXT Function

  • Artykuł

Gets the text that was included in the last error message that was generated.

Syntax

  
String := GETLASTERRORTEXT

Property Value/Return Value

Type: Text

The text string that was contained in the last error message that was generated by Dynamics NAV.

If no error has occurred, then the function returns an empty string.

Remarks

If you call the GETLASTERRORTEXT function immediately after you call the CLEARLASTERROR function, then an empty string is returned.

The result of the GETLASTERRORCODE Functionis not translated into the local language. The result of the GETLASTERRORTEXT function is translated into the local language.

Example

If you call the Codeunit.RUN function to run a codeunit and an error occurs in the codeunit, then the error is displayed. However, if you also use the return value of the Codeunit.RUN function, then the error is not displayed. In this case, you can use the GETLASTERRORTEXT function to determine whether an error has occurred and to see the text of the last error message that was generated. This example shows how to use the GETLASTERRORTEXT function. This example requires that you create two codeunits. Codeunit 50001 generates an error. Codeunit 50002 runs codeunit 50001 and if an error occurs, then it displays the text of the error.

// Codeunit 50001  
// OnRun trigger  
ERROR(‘Some error message.’);  
  
// Codeunit 50002  
// OnRun trigger  
CLEARLASTERROR();  
IF NOT Codeunit.RUN(50001) THEN  
  MESSAGE(‘The last error was: ’ + GETLASTERRORTEXT);

In this example, because the IF statement uses the return value of the Codeunit.RUN function, the error from codeunit 50001 is not displayed. Instead, you use the GETLASTERRORTEXT function to display the error.

When you run codeunit 50002, the message window displays the following:

The last error was: Some error message.
