WORD structSize

The size of this structure.

WORD ValueType

Specifies the data type of the parameter field. The Crystal Report Engine supports the following data types: number, currency, Boolean, date, and string. Use the appropriate constant from the Crystal Developers Help.

WORD DefaultValueSet

Indicates whether or not a default value was set for the parameter field. The value can be either TRUE (1) if the field was given a default value or FALSE (0) if it was not.

WORD CurrentValueSet

Indicates whether or not a current value was set for the parameter field.

char Name [ PE_PF_NAME_LEN ]

Specifies the name of the parameter field assigned by the user when the parameter was inserted into the report or the name that was set from code.

char Prompt [ PE_PF_PROMPT_LEN ]

Specifies the prompting text, if any, that appears in the prompting dialog box. This will be either the prompt assigned by the user when the parameter field was inserted into the report or the prompt that was set from code.

PEValueInfo DefaultValue

Specifies the default value assigned to the parameter field if one was set. If the DefaultValueSet member is false, this value is meaningless.

PEValueInfo CurrentValue

Specifies the current value assigned to the parameter field. If CurrentValueSet is False, this value is meaningless. To discard the current value, refresh data.

char ReportName [ PE_PF_REPORT_NAME_LEN ]

The name of the report this parameter field applies to.

WORD needsCurrentValue

TRUE (1) if a current value is required. FALSE (0) if a current value has already been supplied for the parameter field.
