# @ohos.bundle.appControl (appControl)

The **appControl** module provides APIs for setting, obtaining, and deleting the disposed status of an application. An application in the disposed status is forbidden to run. When a user clicks the application icon on the home screen, the corresponding page is displayed based on the disposal intent.  

> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
>
> The APIs provided by this module are system APIs.

## Modules to Import

``` ts
import appControl from '@ohos.bundle.appControl'
```

## appControl.setDisposedStatus

## Obtaining appId of an Application

**appId** is the unique identifier of an application and is determined by the bundle name and signature information of the application. It can be obtained by calling [getBundleInfo](js-apis-bundleManager.md#bundlemanagergetbundleinfo).

**Example**

```ts
import bundleManager from '@ohos.bundle.bundleManager';
import { BusinessError } from '@ohos.base';

let bundleName = 'com.example.myapplication';
let appId: string;
try {
  bundleManager.getBundleInfo(bundleName, bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_SIGNATURE_INFO)
    .then((data) => {
      appId = data.signatureInfo.appId;
      console.info("appId is " + appId);
    }).catch((error: BusinessError) => {
      let message = (error as BusinessError).message;
      console.error("getBundleInfo failed " + message);
  });
} catch (error) {
    let message = (error as BusinessError).message;
    console.error("getBundleInfo failed " + message);
}
```
