Declaration

ObjPropertyObj.ParamType(Index)

Read-Only Property

ObjPropertyObj	An expression, variable or parameter that specifies a reference to an ObjProperty object
Index	[in]	Required	Integer

Applies To

The property is applied to the following object:

ObjProperty

Parameters

The property has the following parameter:

Index

The zero-based index of the desired parameter in the properties parameter's list. To get the total number of parameters, use the ObjProperty.ParamCount property.

Property Value

An integer that indicates the parameter data type. The following types are possible:

Constant Name	Hex Value	Integer Value	Description
`varEmpty`	`0000h`	0	Empty (uninitialized).
`varNull`	`0001h`	1	Null (no valid data).
`varSmallInt`	`0002h`	2	Signed 16-bit integer.
`varInteger`	`0003h`	3	Signed 32-bit integer.
`varSingle`	`0004h`	4	Single-precision floating-point number. Number of significant digits: 7-8.
`varDouble`	`0005h`	5	Double-precision floating-point number. Number of significant digits: 15-16.
`varCurrency`	`0006h`	6	High-precision floating-point number. Number of significant digits: 19-20. Intended to minimize rounding errors in monetary calculations.
`varDate`	`0007h`	7	OLE-compatible TDateTime type.
`varOleStr`	`0008h`	8	String of 16-bit Unicode characters.
`varDispatch`	`0009h`	9	Automation object that implements `IDispatch` interface.
`varError`	`000Ah`	10	Code of an OS error.
`varBoolean`	`000Bh`	11	Boolean.
`varVariant`	`000Ch`	12	Variant.
`varUnknown`	`000Dh`	13	Reference to an unknown OLE object.
`varShortInt`	`0010h`	16	Signed 8-bit integer.
`varByte`	`0011h`	17	Unsigned 8-bit integer.
`varWord`	`0012h`	18	Unsigned 16-bit integer.
`varLongWord`	`0013h`	19	Unsigned 32-bit integer.
`varInt64`	`0014h`	20	Signed 64-bit integer.
`varStrArg`	`48h`	72	A COM-compatible string.
`varString`	`100h`	256	A reference to a dynamically allocated string (not COM-compatible).
`varAny`	`101h`	257	A Variant that can contain any value.
`varArray`	`2000h`	8192	Array. Type of array elements is specified by the lower bits. For example, `2003h` is an array of integers.
`varByRef`	`4000h`	16384	Reference to a value of the type given by the lower bits. For example, `4007h` is a reference to a date.

Remarks

If you use Python or DelphiScript, you should enclose the parameter of the ParamType property in square brackets: ParamType[Index].
