Description
Use the ValueType
property to get the data type of the value returned by the method that the given aqObjMethodObj
object provides information about. To check whether the method returns a value, use the HasRetValue property.
Declaration
aqObjMethodObj.ValueType
Read-Only Property | Integer |
aqObjMethodObj | An expression, variable or parameter that specifies a reference to an aqObjMethod object |
Applies To
The property is applied to the following object:
Property Value
An integer that indicates the type of the method's return value. The following types are possible:
Constant Name | Hex Value | Integer Value | Description |

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. |

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. |
Example
The code below specifies the type of the value that is returned by the Click
method.
