debugging

问题 I am creating a C# application using Visual Studio that uses an SQLExpress database. When I hit f5 to debug the application and make changes to the database I believe what is happening is there is a copy of the database in the bin/debug folder that changes are being made to. However, when I stop the debugging and then hit f5 the next time a new copy of the database is being put in the bin/debug folder so that all the changes made the last time are gone. My question is: Is there a way that

问题 I am using Eclipse 3.5 and I attached the src.zip to my global settings in Eclipse. Windows--> Preferences -->Java -->Installed JREs -->rt.jar - Source attachment - ...../jdk/src.zip I am successfully able to step in the java core library .class files and view the source code.

When I debug the breakpoints in my source code (my projects) are working good but when I need to step into the java

问题 I have an EXE file using a DLL file which is using another DLL file. This situation has arisen: In DLL file 1: class abc { static bool FindSubFolders(const std::string & sFolderToCheck, std::vector< std::string > & vecSubFoldersFound); } In DLL file 2: void aFunction() { std::vector<std::string> folders; std::string sLocation; ... abc::FindSubFolders(sLocation, folders) } In release mode, everything works fine. But in debug mode, I come up with an assertion failure in the destructor of one of

问题 I have a Samsung Spica i5700 which I already have updated to Android 2.1. I am using the phone with an application called Run.GPS (http://www.rungps.net). This application logs data such as GPS position, route, speed, bearing etc. It can also log heartrate provided the user has a Zephyr HxM bluetooth heart rate monitor ("HxM"), which I do have. I can pair the HxM to the phone through the standard bluetooth utility. I'm prompted for the PIN, which I enter and the device is shown as 'Paired but

问题 I know I can find out if a variable is null in Java using these techniques: if (var==null) -> too much work try { ... } catch (NullPointerException e) { ...} -> it tells me what line is throwing the exception using the debugger -> by hand, too slow Consider this line of code: if (this.superSL.items.get(name).getSource().compareTo(VIsualShoppingList.Source_EXTRA)==0) { I would like to know if there's a generic way to find out programatically what variable (not just the line) is throwing the

问题 How can I print the values being sent to the sqlite database while using Core Data SQL Debug? Using the " -com.apple.CoreData.SQLDebug 1 " in my " Arguments Passed on Launch " debug options prints the SQL structure just fine (you can check see how to use this here: XCode4 and Core Data: How to enable SQL Debugging) But the problem is that the NSLog printed is something like UPDATE ZTABLE SET ZCOLUMN = ? WHERE ZID = ? and it does not help at all if you are trying to see what is the full SQL

问题 Using VB6, I have created an Outlook plugin, that has a property page. The property page is an OCX control. When I compile the project to an OCX file, and then run OUTLOOK, things work fine: I am able to see my OCX as a tab in the Outlook options. However, when I try to debug by running the OCX in VB6 I get an error. My debugging is started like this: 1) Debug options set to Wait for components to be created" 2) F5-RUN project in VB6. 3) Start Outlook. 4) Get the error: "Cannot display "MyOcx

问题 I feel like I'm missing something very simple here. I have Eclipse set up to break on all exceptions. So, let's say that it breaks on an AssertationFailedException. The Debug window will show that thread suspended and has the following data: Thread [Thread-1] (Suspended (exception AssertionFailedException)) ContactManager.addContact(String) line: 93 ContactManager$ContactDataCallback.dispatch(String, Element, ClientConnector) line: 118 PacketHandler.handle(FractusPacket) line: 173

问题 I'm developing a webapplication (asp.net mvc 4) with Microsoft Visual Studio 2012, and as the solution is getting bigger, the debug is getting slower. Need to know if there is a way to debug only my client side (javascript) on visual studio instead of the entire application (server+client). Is there any way to attach to process of IE and get the breakpoints working ....? Not interested on get the debugger running on entire client/server application, just client . 回答1: First open Visual studio

问题 Under linux, can I use GDB to debug a process that is currently running? 回答1: Yes. Use the attach command. Check out this link for more information. Typing help attach at a GDB console gives the following: (gdb) help attach Attach to a process or file outside of GDB. This command attaches to another target, of the same type as your last " target " command (" info files " will show your target stack). The command may take as argument a process id, a process name (with an optional process-id as
