objective c - Watching variables in Xcode -

-

I'm looking at a variable with Xcode. I am following the instructions by pausing on a breakpoint, selecting Run> Variables View> ... but with the exception of "Enable Data Formats", all the options have been deepened. idea?

I am using Xcode version 3.1.3.

I unfortunately, the clock pens created from the run menu are not available for me to work. Being aware of the thing is that when the scope of a variable is over, the clock's check may be invalid.

If you do not believe in a bit more depth, then you can use the low level gdb for example to determine the status of a clock for memory address For, in the guide you've linked, they show how to view the variable path which is an indicator with the value 0xbfffeb70 . To manually set the location of a clock for that address, click on the debugger console (where debugging output is printed) after prompting "(gdb)" and type something like this: 

  clock * (Int *) 0xbfffeb70)

Secret syntax is required because gdb is expected to input as C expression. For a little more detail, and go to the section titled "Using Hardware Watchpoints" (I'm testing on an Intel machine, it is not sure how the PowerPC handles it. ) When you set the clock points in this way, Xcode will alert you with a drop-down sheet when a clock bar will arrive and tell you how the value changed, and go to the GDB console only Will reproduce the print.

How to Create Master-Details view using Asp.Net MVC framework -

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...

delphi - Mouseover hint for TChart series value -

-
I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);
