# AviWriter.ShowOptionDialog Property 
 
Gets/sets a value which specifies whether to display the options dialog to specify the writer object settings.
 
**Namespace:** [Aurigma.GraphicsMill.Codecs](https://www.graphicsmill.com/docs/gm5/N_Aurigma_GraphicsMill_Codecs.htm.md)
 **Assembly:** Aurigma.GraphicsMill.Codecs.AviProcessor (in Aurigma.GraphicsMill.Codecs.AviProcessor.dll)
 
## Syntax
  
```
Public Property ShowOptionDialog As Boolean
```
 
```csharp
public bool ShowOptionDialog { get; set; }
```
 
### Property Value
A boolean value which whether to display the options dialog to specify the writer object settings.
 
## Remarks
  
Set this value to **true** whenever you want the user to specify AVI compressor parameters from the user interface rather than to set them programmatically. In this case the dialog associated with the compressor will be displayed. It may provide more control on parameters rather than you can do programmatically. Those parameters of the writer which you specify in the code will be used as initial values of controls on the dialog.
 
The dialog will be displayed when the very first frame will be added to the writer.
 
To make this dialog integrated with your application closer, use the [OptionsDialogParentHandle](https://www.graphicsmill.com/docs/gm5/P_Aurigma_GraphicsMill_Codecs_AviWriter_OptionsDialogParentHandle.htm.md) property.
 
**Note** 
You should set this value **before** you open the writer object. You cannot change it when the writer is already opened!
