Firefox crash instantiating NPAPI plugin -


I already had a complete plugin working as a very simple implementation with many global and stable variables, I have now changed it to an object based design, so I can safely instantify several instances.

However, since I have done this, when creating an example of a plugin, it becomes MyScriptableNPObject :: NewObject () method, where it tries to call the createobject but never Also does not return and the browser crashes. 

  ScriptableNPObject * ScriptableNPObject :: NewObject (NPP npp) {_DebugLog ("ScriptableNPObject :: NewObject"); ScriptTableNPOBject * Newbase = (MyScacheNOPObject *) NPNFunks- & gt; ProjectObact (NPP, & amp; _npclass); _DebugLog ("ScriptableNPObject :: NewObject - end"); Return new obz; }

I'm getting some basic logging as a quick way to debug it and I can see that this method is expected from getValue (), but never end logs On getting out, something is obviously going wrong in the createobject ().

I have defined my own allocation () method for NPObject and NP class can be defined properly, as far as I can tell, these are as follows - 

  NPObject * ScriptableNPObject :: _Olotate (NPP NPP, NP class * Excel) {Return (NPObject *) New ScriptTableNPOject (NPP); } NPClass ScriptableNPObject :: _ npclass = {NP_CLASS_STRUCT_VERSION}, scriptable NPObject :: _ allocated, scriptable NPObject :: _ Deallocate, NULL, ScriptableNPObject :: _HessDystem, ScriptableNPObject :: _Invoice, ScriptableNPObject :: _AnvoicDefault, ScriptableNPObject :: _Hesproperty, ScriptableNPObject :: _GetProperty, NULL, NULL, Faucet, ScriptTableNPOBJJ :: _ Creation;};

npnfuncs struct is also valid from the I can see. That's why I'm a little wrong!

Any help would be greatly appreciated,

thanks.

Check the NPNFanks Pointer in your DPor; I'm sure there is a problem with it.

Except that, get the Mozilla source and create a debug version so that you can take action through the code and see why it is crashing. This is the easiest way to track pointers issues like the ones you have mentioned.

Seriously, however, George said the second (although I am certainly biased): Second, check FireBreath, it will save you a lot of troubleshooting and make the port easier in IE if you Want to do anytime.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
