I have a hierarchy that I need to: break apart doSomething() put it back together the same way it was before. I know how to break things for sure, and have plan about what I need to do when they are flat in hierarchy. The problem is how do I parent them back? Details This is related to my previous question: Freeze scale transform on a parent object with animated child (MAYA MEL/Python script) I need to freeze scale transforms on all nodes in a hierarchy. Problem is that nodes have translate animations on them, and if I try to freeze scale on a parent node, it's child animation gets weird.

How to pass messages from a child user-control to the parent

由 五迷三道 提交于 2019-12-01 08:29:21
This is a Windows Forms / .Net C# question. I have a borderless windows whose transparency key and background color make it completely transparent. Inside the window are a couple of user controls. I want to be able to move the window. I know how to do this on the parent window, but my problem is that the child controls are the only thing visible and thus the only thing click-able. The question is: how can I pass certain messages up to the Parent so the Parent can move when the right mouse button is down and the mouse is moving on any one of the child controls? Or maybe you can suggest another

SQL - detecting loops in parent child relations

I have parent child data in excel which gets loaded into a 3rd party system running MS SQL server. The data represents a directed (hopefully) acyclic graph. 3rd party means I don't have a completely free hand in the schema. The excel data is a concatenation of other files and the possibility exists that in the cross-references between the various files someone has caused a loop - i.e. X is a child of Y (X->Y) then elsewhere (Y->A->B-X). I can write vb, vba etc on the excel or on the SQL server db. The excel file is almost 30k rows so I'm worried about a combinatorial explosion as the data is

Differences between // and /descendant in XPath selecting multiple children

由 时光总嘲笑我的痴心妄想 提交于 2019-12-01 05:20:15
I can't clearly understand the differences between using //element and /descendant::element when selecting multiple children of a base element in XPath. Given this HTML snippet <html> <body> <div class="popupContent"> <table> <tr class="aclass"><td> Hello </td> <td> <input type="text" value="FIRST" /> </td></tr> <tr class="aclass"><td> Goodbye </td> <td> <input type="text" value="SECOND" /> </td></tr> </table> </div> </body> </html> I need to select each input based on its positioning in the table. //div[@class='popupContent']//input[1] this selects the first input //div[@class='popupContent']
