```


## Use RaiseWindowsUiAccessibilityNativeEvent

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using host.windows

// Connect Windows display, session, clipboard, and accessibility services.
windowsUiAccessibilityBridge bridge = windowsUiAccessibilityBridge(1, 1)
text nodeId = "node Id"
int generation = 1
text eventName = "event Name"
text propertyName = "property Name"
text oldText = "old Text"
text newText = "new Text"
int thread = 1
bool result = RaiseWindowsUiAccessibilityNativeEvent(bridge, nodeId, generation, eventName, propertyName, oldText, newText, thread)
Console.Log(Text.From(result))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.host_windows__raisewindowsuiaccessibilitynativeevent"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "host.ui_services"
version = "0.1.0"
path = "../../../yeho/packages/host/ui_services"

[[dependencies]]
package = "host.windows"
version = "0.1.0"
path = "../../../yeho/packages/host/windows"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

```sh
./yeho/build/dolphin-metal/yehoc ./api-examples/host.windows--RaiseWindowsUiAccessibilityNativeEvent/usage --backend cpu-oracle -o /tmp/yeho-example
/tmp/yeho-example
```


Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
