• How to get stack trace of a running process from a Visual Studio add-in?

  - by Jack

  I am writing a Visual Studio add-in in C# and I need access to the currently running process' stack trace. I tried putting this code into my add-in but it returns the add-in's stack trace, not the process I am debugging. System.Diagnostics.StackTrace stacktrace = new System.Diagnostics.StackTrace(true); System.Diagnostics.StackFrame stackframe = stacktrace.GetFrame(0); Any help would be appreciated.

  - by keruilin

  I have -- what I think -- is a simple question. Here's my code: class Fruit < ActiveRecord::Base end class Apple < Fruit end class Kiwi < Fruit end Assume that I have all the STI setup correctly, and there are multiple types of Apple and Kiwi records in the table. From here... fruits = Fruit.find(:all) ...how do I return an array of just Apples from the fruits array?

• How do I get VB6 to integrate with Visual Source Safe 6.0?

  - by Ben McCormack

  We use Visual Source Safe 6.0 at work and VB6 is supposed to integrate smoothly with Source Safe. Both applications are installed on my PC, but VB6 is not showing the options to integrate with Source Safe (e.g. checking out a file, seeing if a file is shared, etc.). What do I need to do to get VB6 to integrate with Source Safe 6.0?

• How do you compile gnu flex in Visual Studio 2005/2008?

• How do I load ascx pages faster in visual studio 2008?

  - by diadem

  One of my (my team's) biggest peeves with VS2008 is the slow speed in which ascx load. It could take up to a couple minutes to do something as simple as a text or style change simply because of the time it takes to load an ascx page into the visual studio text editor. Half the time I'm tempted to check out the file, edit it in notepad, then check it back in. Is there any trick to speeding this up?

• How to fix Visual Studio 2008 freeze?

  - by Mnementh

  My Visual Studio 2008 freezes under some conditions. First, after a restart it is fine, but once it starts updating IntelliSense and counting down items it stops on the same number (the number slightly changed with further changes in the project). After that I get a sure freeze for: right-click in the code to get a context-menu changing from Debug to Release and vice versa quitting visual studio After a freeze I have to kill the process. Any idea what is wrong here?

• Can Perforce and SourceSafe co-exist in Visual Studio?

  - by Chris

  Visual Studio 2008, to be more specific. We're testing out moving to Perforce for source control, so I'd like to install the P4SCC plugin to monkey around with. However, I'd also like to continue using SourceSafe's IDE capabilities for projects that haven't been moved over yet. Can the two co-exist peacefully, or is it one or the other for a specific install of VS?

• Javascript function using "this = " gives "Invalid left-hand side in assignment"

  - by Brian M. Hunt

  I am trying to get a Javascript object to use the "this" assignments of another objects' constructor, as well as assume all that objects' prototype functions. Here's an example of what I'm attempting to accomplish: /* The base - contains assignments to 'this', and prototype functions */ function ObjX(a,b) { this.$a = a, $b = b; } ObjX.prototype.getB() { return this.$b; } function ObjY(a,b,c) { // here's what I'm thinking should work: this = ObjX(a, b * 12); /* and by 'work' I mean ObjY should have the following properties: * ObjY.$a == a, ObjY.$b == b * 12, * and ObjY.getB() == ObjX.prototype.getB() * ... unfortunately I get the error: * Uncaught ReferenceError: Invalid left-hand side in assignment */ this.$c = c; // just to further distinguish ObjY from ObjX. } I'd be grateful for your thoughts on how to have ObjY subsume ObjX's assignments to 'this' (i.e. not have to repeat all the this.$* = * assignments in ObjY's constructor) and have ObjY assume ObjX.prototype. My first thought is to try the following: function ObjY(a,b,c) { this.prototype = new ObjX(a,b*12); } Ideally I'd like to learn how to do this in a prototypal way (i.e. not have to use any of those 'classic' OOP substitutes like Base2). It may be noteworthy that ObjY will be anonymous (e.g. factory['ObjX'] = function(a,b,c) { this = ObjX(a,b*12); ... }) -- if I've the terminology right. Thank you.

• Can I use Visual Studio's testing facilities in native code?

  - by Billy ONeal

  Is it possible to use Visual Studio's testing system with native code? I have no objection to recompiling the code itself under C++/CLI if it's possible the code can be recompiled without changes -- but the production code shipped has to be native code. The Premium Edition comes with code coverage support which I might be able to get cheaply from my University -- but I can get the Professional Edition for free from DreamSpark -- and that's the only thing I can see that I'd use. (But I'd use it a LOT)
