TX Text Control supports system DPI aware applications, which detect the system DPI and scale to it. You make an application such as the [TXWords sample](https://docs.textcontrol.com/tx-text-control-activex/document-editor/word-processor/llms-full.txt) DPI aware with an application manifest embedded in its executable.

### How DPI Awareness Is Set

The recommended way to specify the default DPI awareness of a process is a setting in the application manifest. The manifest must be embedded in the application's executable as an application resource.

### Create the Manifest

The following manifest file configures the DPI awareness. You find this XML file in the samples folder:

```xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <application xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings>
      <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true</dpiAware>
    </windowsSettings>
  </application>
</assembly>
```

The `dpiAware` element with the value `true`, inside `windowsSettings`, declares the application as DPI aware.

### Embed the Manifest

The manifest is embedded in the executable with the tool *Mt.exe*, which is part of the Microsoft Windows Software Development Kit (SDK):

| System | Default installation path of the Windows SDK |
|---|---|
| 32-bit | *\\Program Files\\Windows Kits\\10* |
| 64-bit | *\\Program Files (x86)\\Windows Kits\\10* |

Applications created with Visual Basic 6 are 32-bit applications, but you can use either the 32-bit or the 64-bit version of *Mt.exe*.

Open a **Developer Command Prompt**, or define the environment variables manually, and run one of the following commands:

If your executable already contains a manifest resource, update the resource:

```text
mt -manifest dpiaware.manifest -updateresource:txwords.exe
```

If your executable doesn't contain a manifest resource, embed a new manifest:

```text
mt -manifest dpiaware.manifest -outputresource:txwords.exe
```

### Next Steps
