breakpoints

问题 I've set a breakpoint with the condition... [event.name isEqualToString:@"Some Name"] This works fine. However, when I try to add another breakpoint with the condition... [part.name isEqualToString:@"Some Value With A Pound Sign £"] I get the error... Internal error [IRForTarget]: An Objective-C constant string's string initializer is not an array Stopped due to an error evaluating condition of breakpoint Do I need to escape the pound sign or something? 回答1: There's a bug with the expression

问题 I would like to set a symbolic breakpoint on "objectAtIndex:" method of a specific property in a specific class. See the following code : @interface Foo ... @property (strong,nonatomic) NSMutableArray *fooArray; ... @end I 've tried the following things: -[[Foo fooArray] objectAtIndex:] -[Foo::fooArray objectAtIndex:] -[Foo::fooArray objectAtIndex] Foo::fooArray::objectAtIndex: Foo::fooArray::objectAtIndex Foo::fooArray::objectAtIndex() None of theses solutions work. Any ideas to do the trick

问题 I am setting breakpoints in an external JS file and I haven't been able to get Firebug hit the breakpoint in a consistent way. It works sometimes but most of the times it doesn't. The only way I can get it to work is by switching on "Break on all errors" I have used the debugger; statement as well without any luck. 回答1: If the line numbers aren't green, it seems like Firebug cannot debug that part of code because it is out of scope. So, if you're using something like $(function () { ... });

问题 I'm trying to refactor some rather horrible code at the moment. It's passing around objects in a very convoluted manner I can't keep track of and apparently directly accessing primitives within the objects at some other location in the code. I'm trying to figure out how I can use the debugger to find out when/where an object I'm interested in is used after it gets passed into the confusing black box of code which passes these objects. What I would like is a way to set a watchpoints that

问题 Possible to set a breakpoint for the code block of javascript like the screenshot below. How can we use them? VS always ignores. 回答1: If Internet Explorer is set as the browser when debugging, Visual Studio is, in theory, able to stop at breakpoints set at client side script. To use the feature, you will need to make sure that "Disable script debugging" is checked in your IE Internet Options, Advanced tab. However, I have found VS script debugging to be a bit flaky; the breakpoint is not

问题 I have two C# WinForm projects in the same solution lets call them A and B. Project A starts Process B via a call like below ProcessStartInfo psi = new ProcessStartInfo(); psi.FileName = Task.EXEFilename; psi.WorkingDirectory = Path.GetDirectoryName(Data.EXEFilename); Process.Start(psi); The process B is started correctly. I wanted to debug the process B while I am debugging A. I thought putting a break point in the B would be enough but it is never hit. I have verified that process that is

问题 I recently started having problems with breakpoints in Visual Studio 2010. When I set a breakpoint and then start debugging, another breakpoint appears on some other line nearby. The screenshots below shows the editor after I set a breakpoint, as well as the breakpoints window: As soon as I start debugging, the breakpoint duplicates, as seen in the following screenshots: Why is this happening and how can I stop it? 回答1: It looks like there is a child breakpoint set up, as described in the

问题 Let's say I have 10 breakpoints and I want to clear one but not the other 9. If I toggle the breakpoint on the one that I want to remove, it is resurrected the next time I restart the app. The only way that I know to permanently get rid of it is to clear ALL the breakpoints, which I would rather not do since I would have to reset the other 9. Is there a better way in ANY VS version? 回答1: The breakpoint's state is only temporarily altered if you change it while you're debugging and it's a

问题 Is there a command line argument or an environment variable that disables the "break on first line" feature of the node debugger? 回答1: There are actually two debugger concepts in node: V8 debugger (with its TCP-based protocol) and a node command-line debugger (CLI). When you run node debug app.js , a debugger CLI is run in the master node process and a new child node process is spawned for the debugged script ( node --debug-brk app.js ). The option --debug or --debug-brk is used to turn on V8

问题 When I go to debug my code all my breakpoints are transparently filled (leaving only the outline) and a small triangle with an exclamation point in the middle is in the corner of the break-point. The error when I hover over the break-point is 'The break-point will not currently be hit. The source code is different from the original version.' I had not tried to debug my code in over an hour, and during that time I added a new class with multiple threading functions. Steps I have taken: Clean
