Class Microsoft.VisualBasic.ErrObject Syntax Err.Raise(number[, source[, description[, helpFile, helpContext]]])
number (required; Integer) A numeric code for a particular error
source (optional; String) The name of the project, application, or class responsible for generating the error

Description The Raise method generates a runtime error, specifying the details of the error, including optional online help file information. Usage at a Glance If you supply any of the number, source, description, helpFile, or helpContext arguments when you call the Err.Raise method, they are supplied as values to the Number, Source, Description, HelpFile, and HelpContext properties of the Err object, respectively. Refer to the entries of the individual properties in this chapter for additional information. Visual Basic errors are in the range 0 to 65535. The range 0 to 512 is reserved for system errors; the range 513 to 65535 is available for user-defined errors. When setting the Number property to your own error code, add the vbObjectError constant to your error code. The Raise method does not reinitialize the Err object prior to assigning the values you pass in as arguments. Any Err object property values not explicitly assigned through the Raise method are retained.
Version Differences Although the Error statement is still included in the .NET version of Visual Basic, it should not be used. Use the Err.Raise method instead. See Also Err Object, Err.Clear Method |
