• Using Django.test.client to check template vars

  - by scott

  I've got a view that I'm trying to test with the Client object. Can I get to the variables I injected into the render_to_response of my view? Example View: def myView(request): if request.method == "POST": # do the search return render_to_response('search.html',{'results':results},context_instance=RequestContext(request)) else: return render_to_response('search.html',context_instance=RequestContext(request) Test: c = Client() response = c.post('/school/search/', {'keyword':'beagles'}) # how do I get to the 'results' variable??

• C++ pointer to objects

  - by Tony

  In C++ do you always have initialize a pointer to an object with the new keyword? Or can you just have this too: MyClass *myclass; myclass->DoSomething(); I thought this was a pointer allocated on the stack instead of the heap, but since objects are normally heap allocated, I think my theory is probably faulty?? Please advice.

• Problem migrating membershipProvider functionality from mvc1 to mvc2

  - by Jericho

  I am migrating a web app in mvc1 to mvc2. When it came down to migrating my MembershipProvider authentication I keep getting errors that MembershipProvider and MembershipCreateStatus type cannot be found. I do have the reference to System.Web which to my understanding includes the Security reference, but when I examine the the object, those types do not appear. I am just getting familiar with mvc2, if anyone has any input on this it would be extremely appreciated.

• Generics : List<? extends Animal> is same as List<Animal>?

  - by peakit

  Hi, I am just trying to understand the extends keyword in Java Generics. List<? extends Animal> means we can stuff any object in the List which IS A Animal then won't the following also mean the same thing: List<Animal> Can someone help me know the difference between the above two? To me extends just sound redundant here. Thanks!

• Build a custom drawn control for .net compact framework

  - by Hinek

  I just started on the .net compact framework. I want to draw a Sudoku field on the screen. So I put down a PictureBox and defined a method for the Paint event: private void pictureBoxPlayfield_Paint(object sender, PaintEventArgs e) { // use e.Graphics to draw the grid, numbers and cursor } This works, but you can see as the grid is drawn. So my question is, what is the right/better way to create such a custom control? Is there maybe a way to enable double buffering?

• Why does OpenGL's glDrawArrays() fail with GL_INVALID_OPERATION under Core Profile 3.2, but not 3.3 or 4.2?

  - by metaleap

  I have OpenGL rendering code calling glDrawArrays that works flawlessly when the OpenGL context is (automatically / implicitly obtained) 4.2 but fails consistently (GL_INVALID_OPERATION) with an explicitly requested OpenGL core context 3.2. (Shaders are always set to #version 150 in both cases but that's beside the point here I suspect.) According to specs, there are only two instances when glDrawArrays() fails with GL_INVALID_OPERATION: "if a non-zero buffer object name is bound to an enabled array and the buffer object's data store is currently mapped" -- I'm not doing any buffer mapping at this point "if a geometry shader is active and mode? is incompatible with [...]" -- nope, no geometry shaders as of now. Furthermore: I have verified & double-checked that it's only the glDrawArrays() calls failing. Also double-checked that all arguments passed to glDrawArrays() are identical under both GL versions, buffer bindings too. This happens across 3 different nvidia GPUs and 2 different OSes (Win7 and OSX, both 64-bit -- of course, in OSX we have only the 3.2 context, no 4.2 anyway). It does not happen with an integrated "Intel HD" GPU but for that one, I only get an automatic implicit 3.3 context (trying to explicitly force a 3.2 core profile with this GPU via GLFW here fails the window creation but that's an entirely different issue...) For what it's worth, here's the relevant routine excerpted from the render loop, in Golang: func (me *TMesh) render () { curMesh = me curTechnique.OnRenderMesh() gl.BindBuffer(gl.ARRAY_BUFFER, me.glVertBuf) if me.glElemBuf > 0 { gl.BindBuffer(gl.ELEMENT_ARRAY_BUFFER, me.glElemBuf) gl.VertexAttribPointer(curProg.AttrLocs["aPos"], 3, gl.FLOAT, gl.FALSE, 0, gl.Pointer(nil)) gl.DrawElements(me.glMode, me.glNumIndices, gl.UNSIGNED_INT, gl.Pointer(nil)) gl.BindBuffer(gl.ELEMENT_ARRAY_BUFFER, 0) } else { gl.VertexAttribPointer(curProg.AttrLocs["aPos"], 3, gl.FLOAT, gl.FALSE, 0, gl.Pointer(nil)) /* BOOM! */ gl.DrawArrays(me.glMode, 0, me.glNumVerts) } gl.BindBuffer(gl.ARRAY_BUFFER, 0) } So of course this is part of a bigger render-loop, though the whole "*TMesh" construction for now is just two instances, one a simple cube and the other a simple pyramid. What matters is that the entire drawing loop works flawlessly with no errors reported when GL is queried for errors under both 3.3 and 4.2, yet on 3 nvidia GPUs with an explicit 3.2 core profile fails with an error code that according to spec is only invoked in two specific situations, none of which as far as I can tell apply here. What could be wrong here? Have you ever run into this? Any ideas what I have been missing?

  Hello, I'm writing a multi-threaded application. My worker threads get connection from an environment object as follows:. //EnterCriticalSection(&cs); conn = env->createConnection(username, password, connStr); //LeaveCriticalSection(&cs); For concurrency, should the connection be created in a critical section or not? Does the env need it? And why? Thanks.

• Windows 7 Missing Shortnames

  - by Aaron Bush

  I noticed that if you get a Scripting.File object from certain windows files (Example: any wav in C:\Windows\Media) the Scripting.File.ShortPath property shows the long path. Curious I dropped to the command prompt and tried Dir /A /X and sure enough the short paths were missing from all the files in that directory. Anyone know: A.) What that's all about? B.) How to get the short path of a file that doesn't seem to have one?

• Is there a comprehensive list of the NHibernate event listeners and when they actually fire?

  - by snicker

  So I am looking for a nice list of NHibernate events that actually describes when they are fired, in a typical scenario. IE something like PreUpdateEventListener - Fires when an object that is already persistent is changing I currently just rifle through the source and try to figure it out, but it's kinda painful, and I figure that someone must have done this already at some point.

• How to get only the first row from a java.sql.ResultSet?

  - by llm

  I have a ResultSet object containing all the rows returned from an sql query. I want to be able to (in the java code, NOT force it in the SQL) to be able to take a ResultSet and transform it so that it only contains 1 (the first) row. What would be the way to acheive this? Also, is there another appropriate class (somewhere in java.sql or elsewhere) for storing just a single row rather than trimming my ResultSet? Thanks!

• How do make dependency generation work for C? (Also..decode this sed/make statement!)

  - by Derek

  Hi all. I have a make build system that I am trying to decipher that someone else wrote. I am getting an error when I run it on a redhat system, but not when I run it on my solaris system. The versions of gmake are the same major revision (one off on minor revision). This is for building a C project, and the make system has a global Makefile.global that is inherited by each directory's local Makefile The Makefile.global has all the targets in it, starting with all: $(LIB) $(BIN) where LIB builds libs and BIN builds binaries. jumping down the targets I have $(LIB) : $(GEN_LIB) $(GEN_LIB) : $(GEN_DEPS) $(GEN_OBJS) $(AR) $(ARFLAGS) $(GEN_LIB) $(GEN_OBJS) $(GEN_DEPS) : @set -e; rm -f $@; \ $(CC) $(CDEP_FLAG) $(CFLAGS) $(INCDIRS) `basename $@ | sed 's/\.d/\.c/' | sed 's,^,$(HOME_SRC)/,'` | sed 's,\(.*\)\.o: ,$(GEN_OBJDIR)/\1.o $@ :,g' > [email protected] ; \ cat [email protected] > $@ ; \ cat [email protected] | cut -d: -f2 | grep '\.h' | sed 's,\.h,.h :,g' >> $@ ; \ rm [email protected] $(GEN_OBJS) : $(CC) $(CFLAGS) $(INCDIRS) -c $(*F).c -lmpi -o $@ I think these are all the relevant targets I need to include to answer my question. Definitions of those variables: CC = icc CDEP_FLAG = -M CFLAGS = various compiler flags ifdef type flags INCDIRS = include directory where all .h files are GEN_OBJDIR = /lib/objs HOME_SRC = . GEN_LIB = lib/$(LIB) GEN_DEPDIR=/lib/deps GEN_DEPS = $(addprefix $(GEN_DEPDIR)/,$(addsuffix .d,$(basename $(OBJS)))) I think this has everything covered you need. Basically self explanatory from the names. Now as best I can tell, this is generating in /lib/deps a .d file that has the object and source dependencies in it. In other words, for the utilities.a library, I will get a utils.o and utils.c dependency stack, all in the file utils.d There is some syntax error that is being generated in that file I think, because I get the following error: ../lib/deps/util.d:25: *** target pattern contains no '%'. Stop. gmake[2]: *** [all] Error 2 gmake[1]: *** [all] Error 2 gmake: *** [all] Error 2 I am not sure if my error is in the dependency generation, or some further down part, like the object generation target? If you need further info, let me know, I will add to post

• Achieving C# "readonly" behavior in C++

  - by Tommy Fisk

  Hi guys, this is my first question on stack overflow, so be gentle. Let me first explain the exact behavior I would like to see. If you are familiar with C# then you know that declaring a variable as "readonly" allows a programmer to assign some value to that variable exactly once. Further attempts to modify the variable will result in an error. What I am after: I want to make sure that any and all single-ton classes I define can be predictably instantiated exactly once in my program (more details at the bottom). My approach to realizing my goal is to use extern to declare a global reference to the single-ton (which I will later instantiate at a time I choose. What I have sort of looks like this, namespace Global { extern Singleton& mainInstance; // not defined yet, but it will be later! } int main() { // now that the program has started, go ahead and create the singleton object Singleton& Global::mainInstance = Singleton::GetInstance(); // invalid use of qualified name Global::mainInstance = Singleton::GetInstance(); // doesn't work either :( } class Singleton { /* Some details ommited */ public: Singleton& GetInstance() { static Singleton instance; // exists once for the whole program return instance; } } However this does not really work, and I don't know where to go from here. Some details about what I'm up against: I'm concerned about threading as I am working on code that will deal with game logic while communicating with several third-party processes and other processes I will create. Eventually I would have to implement some kind of synchronization so multiple threads could access the information in the Singleton class without worry. Because I don't know what kinds of optimizations I might like to do, or exactly what threading entails (never done a real project using it), I was thinking that being able to predictably control when Singletons were instantiated would be a Good Thing. Imagine if Process A creates Process B, where B contains several Singletons distributed against multiple files and/or libraries. It could be a real nightmare if I can not reliably ensure the order these singleton objects are instantiated (because they could depend on each other, and calling methods on a NULL object is generally a Bad Thing). If I were in C# I would just use the readonly keyword, but is there any way I can implement this (compiler supported) behavior in C++? Is this even a good idea? Thanks for any feedback.
