我有一个AutomationElement A(MS UI Automation),它代表一个组合框.我想使用Windows API调用在该组合框中选择第n项
IntPtr ComboBox_SetCurSel(IntPtr hWnd, int index)
A.NativeWindowHandle包含组合框的句柄,但为了将其传递给ComboBox_SetCurSel,我需要将其转换int为IntPtr.
怎么样？
我有一个控制台应用程序,它需要一个命令行参数.
int _tmain(int argc, char* argv[])
{
...
printf("Path: %s\n", argv[1]);
...
}
当我使用参数(myprogram.exe D:\myfolder\myfile)运行程序时,它打印Path: D而不是Path: D:\myfolder\myfile.
我应该如何更改提取第一个命令行参数(argv[1])的过程,以便它返回完整路径,而不仅仅是第一个字母？
我试图将路径放在quotes(myprogram.exe "D:\myfolder\myfile")中,但它没有帮助.
我有一个基于Primefaces的应用程序,其中有一些冗长的操作.
当这样的操作正在执行时,我想以某种方式表明这一点(比如显示沙漏或消息,它出现在屏幕的中央).
在Primefaces/JSF中最简单的方法是什么？
我有一个Android活动,其中有一些调用
final ConnectToServerAsyncTask task = new ConnectToServerAsyncTask(...);
和
final Intent intent = new Intent(this, SomeActivity.class);
为了单元测试这个类,我需要能够嘲笑的创建ConnectToServerAsyncTask和Intent(例如使用的Mockito).
有比下面描述的方法更优雅的方法吗？
public class MainActivityOfTheApp extends Activity {
private IAsyncTaskFactory asyncTaskFactory = new AsyncTaskFactory();
private IIntentFactory intentFactory = new IntentFactory();
public void setAsyncTaskFactory(final IAsyncTaskFactory aFactory)
{
asyncTaskFactory = aFactory;
}
public void setIntentFactory(final IIntentFactory aFactory)
{
intentFactory = aFactory;
}
@Override
protected void onResume() {
...
final ConnectToServerAsyncTask task = asyncTaskFactory.create(...);
...
final Intent intent = intentFactory.create(this, OtherActivity.class);
...
}

https://sapes1.sapdevcenter.com/sap/opu/odata/sap/ZCD204_EPM_DEMO_SRV/BusinessPartners('0100000000')/ SalesOrders /？$ expand = SalesOrderItems
我们能够绑定属于每个SalesOrder的根级项目.但是,如果将SalesOrderItems子数据绑定到子进程,我们遇到问题SalesOrder.
我们无法将SalesOrderItems的字段绑定到任何对象.我们尝试使用{SalesOrderItems/results/QuantityUnit},{SalesOrderItems/QuantityUnit}没有太多运气.
你能建议任何替代方案吗？
SalesOrder和SalesOrderItem之间有1..m基数
