System 2.0.0.0 4.0.0.0 System.Enum The control delegates the actual responsibility for parsing the input characters to the class. Many of the methods of , in addition to returning a success result, also provide an additional output parameter of type . This enumeration provides additional information about the operation of the method. The method can be used to convert a value into a success value. Specifies values that succinctly describe the results of a masked text parsing operation. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed.An input character was encountered that was not alphanumeric. . Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed.An input character was encountered that was not a member of the ASCII character set. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Success. The operation succeeded because a literal, prompt or space character was an escaped character. For more information about escaped characters, see the method. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed. An input character was encountered that was not a digit. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed. The program encountered an input character that was not valid. For more information about characters that are not valid, see the method. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed. An input character was encountered that was not a letter. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Success. The primary operation was not performed because it was not needed; therefore, no side effect was produced. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed. The current position in the formatted string is a literal character. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed. The specified position is not in the range of the target string; typically it is either less than zero or greater then the length of the target string. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed. The prompt character is not valid at input, perhaps because the property is set to false. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Success. The primary operation was not performed because it was not needed, but the method produced a side effect. For example, the method can delete an unassigned edit position, which causes left-shifting of subsequent characters in the formatted string. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed. An input character was encountered that was not a signed digit. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Success. The primary operation succeeded. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Operation did not succeed. There were not enough edit positions available to fulfill the request. Field 2.0.0.0 4.0.0.0 System.ComponentModel.MaskedTextResultHint Unknown. The result of the operation could not be determined.
