Usage of Biztalk SAP Adapter without Biztalk Server to connect .NET and SAP

ぐ巨炮叔叔 提交于 2019-12-06 08:22:51
问题 Is it possible to use the Biztalk adapter pack whithout a Biztalk installation (Biztalk license is available)? I want to use the Biztalk Adapter for SAP RFC calls within a .NET Application (as a replacement of the SAP Connector for .NET , which is unfortunately no longer maintened by SAP and I don't can use third party products like " ErpConnect "). Makes this idea sense or not ? This questions can be also seen in conjunction of my question concerning connecting SAP and Microsoft (Microsoft

Android 开发中踩过的坑之十三: ListView中的getAdapter

筅森魡賤 提交于 2019-12-06 07:53:38
使用Adapter, 有时候为了省事直接强制类型转换, 却出现转换异常,原来 ListView中的getAdapter()方法返回的可能 并不是setAdapter传入的那个adapter 为什么? 因为ListView有个特殊功能 : 添加Header和Footer. 使用ListView的时候可以设置页眉(header)和页脚(footer). 而且可以设置很多页眉和页脚. 打开源码跟进去细看, 就会发现, 一旦设置里页眉页脚, 那ListView的adapter就变了. 变成一个" HeaderViewListAdapter "了, 这个HeaderViewListAdapter 先包装了你传入的adapter , 然后替代它, 当执行getView(), getItem()之类的方法时, 通过运算得出 adapter对应的 getView(), getItem()结果并返回, 如此一来, 必然不能将被包装的类强制转换成包装类了. 解决办法倒也简单, 在需要引用的地方添加变量, 或者通过方法参数传入对象就好了. 但是要注意, adapter通常带有较大的数据, 有时甚至可能保定Context, Veiw, 等大内存的对象. 此时要注意在合适的时机释放所有对adapter的引用(变量置为null). 以保证大对象不会产生内存泄露 来源: oschina 链接: https:/

Get recyclerview listener in another class

[亡魂溺海] 提交于 2019-12-06 05:25:56
I have a main activity that displays an ImageView and below that a RecyclerView . In the adapter for the RecyclerView I implemented onClickListner on the view holder and it is working fine. However I need the click to set the image in the main activity when the button is clicked but I cannot see anyway to implement a listner in the main activity to get the results from the adapter to the main activity. I tried the using the onClick as below but that gives a null pointer exception . class AddVideoTitleViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { TextView

Android - Does SimpleCursorAdapter allow multiple layouts like BaseAdapter?

帅比萌擦擦* 提交于 2019-12-06 05:16:42
问题 I know you can create a custom Adapter extending BaseAdapter and create various layouts which can be inflated depending on which row the AdapterView is at.. But is there any way to get a simple amount of customization with a SimpleCursorAdapter ? Eg. I have a database and I would like to query it and return the results to a ListView with alternating row layouts. Will SimpleCursorAdapter do? Or are there any elegant solutions for this? Cheers 回答1: But is there any way to get a simple amount of

STL 配接器(adapters)

南笙酒味 提交于 2019-12-06 04:59:12
定义 配接器(adapters):将一个class的接口,转换为另一个class的接口,使得原来不能一起使用相互兼容的classes,可以一起协同工作。 配接器是一种设计模式。 STL中提供的各种配接器可分为三类: 改变仿函数接口者,称之为function adapter 改变容器接口者,称之为container adapter 改变迭代器接口者,称之为iterator adapter container adapter graph LR deque --- stack deque --- queue iterator adapter graph LR iterator --- reverse_iterator iterator --- Insert_iterator iterator --- iostream_iterator Insert_iterator --- back_insert_iterator Insert_iterator --- front_insert_iterator Insert_iterator --- insert_iterator 插入迭代器:将一般迭代器的赋值操作转变为插入操作。 reverse adapter 反向迭代器:将一般迭代器的行进方向逆转,使得原本应该前进的operator++变为了后退操作,原本应该后退的operator-

Weblogic could not find resource adapter with “correct” JNDI name for binding

问题 I am trying to bind my message driven bean with Oracle JCA file adapter (which is included in the SOA suite) on Weblogic 10.3.5. So that my MDB can get notified when there is any .txt file is moved to specific directory. After launching a Weblogic domain with SOA features supported, the file adapter is automatically deployed. On Weblogic console I can see the file adapter is deployed as a "Resource Adapter", health is "OK", state is "Active", as shown below: Also I run the tests of the file

ListView与Adapter。。

血红的双手。 提交于 2019-12-06 02:57:32
在开发的过程中,发现ListView这个组件用得非常多,而ListView的使用过程中,又往往与Adapter结下了不结之缘。 ListView是什么呢?Adapter又是什么呢? ListView是Android手机系统中广泛使用的一个组件,以垂直的方式显示所有的列表项,在显示联系人名单等都用到了ListView。 Adapter是把数据和用户界面View绑定到一起的桥梁类,如ArrayAdapter、CursorAdapter、SimpleAdapter、ResourceCursorAdapter、SimpleCursorAdapter都是常见的,我用得比较多的也就是前三种。而这三种有什么区别呢?其实主要是数据源的不同。1.String[]: ArrayAdapter 2. List<Map<String,?>>: SimpleAdapter 3. 数据库Cursor: SimpleCursorAdapter,所以要选择好使用。 ListView与ArrayAdapter 创建ListView有三种方法,第一种是在xml文件里使用ListView组件,第二种是直接继承ListActivity,第三种是在java文件中直接new出一个ListView对象,建议是在xml文件里使用ListView组件,因为属性控制各方面都比较好,但是也要看你项目的具体要求。 main.xml <?

Override buildURL method to include parent model's id

问题 Regarding ember-data and subclassing DS.RESTAdapter to override buildURL . I have two endpoints. Lets say they are: example.com/users/user-id example.com/users/user-id/images Replace "user-id" with the actual user id. So I have two models: App.User = DS.Model.extend images: DS.hasMany 'image', async: true inverse: 'user' App.Image = DS.Model.extend user: DS.belongsTo 'user', async: true inverse: 'images' However, the payload from /users/user-id endpoints do not return the image ids. I do not

I have created a custom Base Adapter class, to populate a list view with image and text. The code of class is as below : public class ViewAdapter extends BaseAdapter { private Activity activity; private String[] data; private static LayoutInflater inflater=null; public ImageLoader imageLoader; private ArrayList<String> items; public ViewAdapter(Activity a, ArrayList<String> items,String[] d) { this.items = items; activity = a; data=d; inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); imageLoader=new ImageLoader(activity.getApplicationContext()); } public

Non-clickable Listview Item with Visible Divider

烈酒焚心 提交于 2019-12-05 21:57:28
I would like to disable clicking of a Listview item. One solution is to override areAllItemsEnabled() to always return false, and isEnabled() to return false for a particular position. However, this causes the divider lines around the particular Listview item to disappear. A few people suggested returning true for areAllItemsEnabled() and false for isEnabled() , but this is not working for me. I am hesitant to place a divider line in manually because I would need to add a parent layout to the item XML. Is there a way to set a Listview item to be non-clickable and still retain The solution is
