问题 I have 4 choices assigned to 4 buttons. One of the choices is correct and it is assigned to the string "correctAnswerString" The 4 buttons call "action:@selector(submitAnswer:)" I want to be able to access the string "correctAnswerString" in the "submit Answer" method and compare if the button with the correct answer has been pressed.

问题 I have a report in SSRS. The report has one string parameter and one integer parameter. Both parameters have default values set up. I have a text box with an Action to the report itself (drill-through report).

The integer parameter keeps its default value when the drill-through report is rendered. Do you know if there's an issue with integer parameters in

问题 Using JavaScript, say I have a function X, and in that function an object called objectX is created. function X returns objectX. Later in the code function Z(somevar, anObject) receives objectX as one of it's parameters. Now in function Z, is objectX and all its properties referred to as anObject inside function Z? And what happens if function Z returns anObject? Will the rest of the code see the object as "objectX" or "anObject"? function X() { ... objectX = {}; ... return objectX; } X();

问题 I am attempting to write a PHP script that will allow for me to select a few files to download from a predetermined location. I'd like my script to pass an array to a Powershell script that id written earlier and have my Powershell script handle the downloading (basically the php file just needs to tell the powershell file what needs to be downloaded).
