问题 I need to assign N entities (each with possible parents and possible children) to M computation nodes while satisfying the following optimization conditions: Children of an entity want to be assigned to the same computation node (to maximize data locality among siblings) The distribution of entities should be as even as possible (i.e. no overtaxing of a single node). I'm looking for some suggestions on heuristic methods to solve this problem. I've read http://en.wikipedia.org/wiki/Assignment

Any idea how to solve this problem. I am using

问题 How to get the focused cell value at the time focussing on the cell by using the keyboard arrow keys 回答1: You can either get the focused cell by using var focusedCell = gridOptions.api.getFocusedCell(); or use the onCellFocused event. Both give you the following properties: rowIndex: number column: Column Use the row-index to retrieve the row-node: var row = gridOptions.api.getDisplayedRowAtIndex(rowIndex); After that you can use those properties to retrieve the raw value of the cell: var

问题 This problem stems from not being able to get my TextBlock to wrap. Basically as a last-ditch attempt I am setting MaxWidth on my container grid's columns. I was surprised to find that my child label and textbox still do whatever they want (bad children, BAD) and are not limited by my grid column's MaxWidth="200". What I'm really trying to do is let my TextBlock fill available width and wrap if necessary. So far after trying many variations of HorizontalAlignment="Stretch" on every known

问题 I'm working on a project where I have a single GridPanel on a page. The panel can display any number of rows and I have the autoHeight property set, which causes the GridPanel to expand to fit the number of rows. I now want a horizontal scrollbar because on some resolutions not all columns get displayed (and I cannot reduce the number of columns). If I set the autoHeight I have no horizontal scrollbar, if I do not set it and set a fixed height I have a horizontal scrollbar but the GridPanel

问题 I want that a Out-GridView closes after a specific time, e.g after 10 seconds. Not used to the windows powershell. Any answer helps. 回答1: Unfortunately, PowerShell doesn't natively offer finding and closing arbitrary GUI windows, but you can use the Add-Type cmdlet with ad hoc-compiled C# code that in turn uses P/Invoke declarations to access the Windows API. The following is a working example: It defines a distinct window title to use for the Out-GridView call so that the window can be
