# SolverGet Function

Returns information about current settings for Solver. The settings are specified in the **Solver Parameters** and **Solver Options** dialog boxes.

**Note** The Solver add-in is not enabled by default. Before you can use this function, you must have the Solver add-in enabled and installed. For information about how to do that, see Using the Solver VBA Functions. After the Solver add-in is installed, you must establish a reference to the Solver add-in. In the Visual Basic Editor, with a module active, click **References** on the **Tools** menu, and then select **Solver** under **Available References**. If **Solver** does not appear under **Available References**, click **Browse**, and then open Solver.xlam in the \Program Files\Microsoft Office\Office14\Library\SOLVER subfolder.

**SolverGet**(** TypeNum**,

**)**

*SheetName***TypeNum** Required **Integer**. A number specifying the type of information you want. The following settings are specified in the **Solver Parameters** dialog box.

TypeNum |
Returns |
---|---|

1 | The reference in the Set Target Cell box, or the #N/A error value if Solver has not been used on the active sheet. |

2 | A number corresponding to the Equal To option: 1 represents Max, 2 represents Min, and 3 represents Value Of. |

3 | The value in the Value Of box. |

4 | The reference (as a multiple reference, if necessary) in the By Changing Cells box. |

5 | The number of constraints. |

6 | An array of the left sides of the constraints, in text form. |

7 | An array of numbers corresponding to the relationships between the left and right sides of the constraints: 1 represents <=, 2 represents =, 3 represents >=, 4 represents int, and 5 represents bin. |

8 | An array of the right sides of the constraints, in text form. |

13 | True if the Simple LP Solving method is selected; False if another Solving method is selected. |

20 | True if the Make Unconstrained Variables Non-Negative check box is selected; False if it is cleared. |

The following settings are specified in the **Solver Options** dialog box.

TypeNum |
Returns |
---|---|

9 | The Max Time (Seconds) option (All Methods tab). |

10 | The Iterations option (All Methods tab). |

11 | The Constraint Precision option (All Methods tab). |

12 | The Integer Optimality (%) option (All Methods tab). |

14 | True if the Show Iteration Results check box is selected; False if it is cleared. |

15 | True if the Use Automatic Scaling check box is selected; False if it is cleared (All Methods tab). |

16 | A number corresponding to the type of estimates: 1 represents Tangent, and 2 represents Quadratic. |

17 | A number corresponding to the Derivatives option in the GRG Nonlinear tab: 1 represents Forward, and 2 represents Central (GRG Nonlinear tab). |

18 | A number corresponding to the type of search: 1 represents Newton, and 2 represents Conjugate. |

19 | The Convergence tolerance (GRG Nonlinear tab and Evolutionary tab). |

21 | The Population Size option (GRG Nonlinear tab and Evolutionary tab). |

22 | The Random Seed option(GRG Nonlinear tab and Evolutionary tab). |

23 | True if the Use Multistart check box is selected; False if it is cleared (GRG Nonlinear tab). |

24 | True if the Require Bounds on Variables check box is selected; False if it is cleared (GRG Nonlinear tab and Evolutionary tab). |

25 | The Mutation Rate option (Evolutionary tab). |

26 | The Max Subproblems option (All Methods tab). |

27 | The Max Feasible Solutions option (All Methods tab). |

28 | The Ignore Integer Constraints option (All Methods tab). |

29 | The Maximum Time without Improvement option (Evolutionary tab). |

**SheetName** Optional **Variant**. The name of the sheet that contains the Solver model for which you want information. If ** SheetName** is omitted, this sheet is assumed to be the active sheet.

## Example

This example displays a message if you have not used Solver on Sheet1.

```
Worksheets("Sheet1").Activate
state = SolverGet(TypeNum:=1)
If IsError(State) Then
MsgBox "You have not used Solver on the active sheet"
End If
```
