## How to exclude WIA sources in the source list?

> Applicable to Windows only

There are two ways to achieve this:

* Set [IfUseTwainDSM](/_articles/info/api/WebTwain_Acquire.md#ifusetwaindsm) to `true`

``` javascript
DWTObject.IfUseTwainDSM = true;
```

* Filter sources before listing them

``` javascript
var sources = DWTObject.GetSourceNames();
sources = sources.filter(source => !source.toLowerCase().includes('wia'));
```
