debugging

问题 I am making my first silverlight application. I only put a textbox and a button. I tried to debugged and It doesn't work. I tried going to the web project. property pages->start options->debuggers and silverlight is already checked. so I need help. Why is not working???? Thanks Nora 回答1: You need to disable out-of-process hosting for silverlight. Go to about:config in Firefox, look for key "dom.ipc.plugins.enabled.npctrl.dll" and set the value to false (doubleclick). 回答2: Are you using

问题 I am trying to use Flex builder for the first time in years. I haven't used the "Run Application" option before, and when I do that now it tells me "Errors exist in required projects" and whether I should proceed. I would like to debug those errors. Does anyone know how I can do that? PS: When I click the "Debug" button, it does exactly the same thing. I don't see error output in the console views. 回答1: Ensure the Problems view is open (Window -> Show View -> Problems). That will show you

问题 Everyone runs into syntax errors. Even experienced programmers make typos. For newcomers, it's just part of the learning process. However, it's often easy to interpret error messages such as: PHP Parse error: syntax error, unexpected '{' in index.php on line 20 The unexpected symbol isn't always the real culprit. But the line number gives a rough idea of where to start looking. Always look at the code context . The syntax mistake often hides in the mentioned or in previous code lines .

问题 Quite often I will try and run a PHP script and just get a blank screen back. No error message; just an empty screen. The cause might have been a simple syntax error (wrong bracket, missing semicolon), or a failed function call, or something else entirely. It is very difficult to figure out what went wrong. I end up commenting out code, entering "echo" statements everywhere, etc. trying to narrow down the problem. But there surely must be a better way, right? Is there a way to get PHP to

问题 This is a big project, actually a virtual machine of my custom design. Under certain circumstances, program crashes with a segmentation fault every time when I run it on its own, but within GDB under those same circumstances it runs perfectly and never crashes! I am giving it the exact same parameters and input when running inside and outside GDB. So basically, I can't find the bug with GDB because it never has any problem when I use GDB. The binary has been compiled with gcc -g option. When

问题 I needed some sample code to test out the AudioRecord class and I came across this website LINK TO THE SOURCE CODE However the program doesn't run, and hangs after a while. When the program starts it gives blank screen and does not do anything, and after a while a message box pops up saying the program is not responding and whether I want to close it. So I added Toast.makeText(getApplicationContext(), "HERE", Toast.LENGTH_SHORT).show(); as the first line of onCreate() in MainActivity , but

问题 I have a small (<300 lines) C++ file in a C++ CLI project in Visual Studio 2010. I have crafted some macros which do different things depending on the Debug/Release configurations. I would like to be able to look at the resulting .obj files (when I compile in Debug and Release) and be able to compare the two. The hard part is that files are binary and I do not understand their format. I am sure there are other ways to ensure that the macro is not destructive - e.g. try it out at runtime in
