  - by paultop6

  Hi Guys, More GTK questions, im trying to compile some code and im getting the following error: error: invalid use of member (did you forget the ‘&’ ?) This is comming from the g_signal_connect call: g_signal_connect ((gpointer) Drawing_Area_CPU, "expose-event", G_CALLBACK (graph_expose), NULL); Drawing_Area_CPU is a GtkWidget* and graph_expose is defined as: gboolean graph_expose(GtkWidget *widget, GdkEventExpose *event, gpointer data); So far as i can tell im doing everything right, but still i get this error.

• What causes Apache Environment Variable set using mod_rewrite to have "redirect_" appended to name?

  - by trowel

  I am trying to set Apache environment variables (for use in PHP) with the [E=VAR:VAL] flag on RewriteRule rules in an .htaccess file. I have already discovered the variables are accessed in PHP as server variables $_SERVER rather than $_ENV (which makes a certain amount of sense). However, my problem is for some rules the [E=VAR:VAL] flag works as expected and I end up with a variable $_SERVER['VAR'] but for other rules I end with a variable $_SERVER['REDIRECT_VAR'] or $_SERVER['REDIRECT_REDIRECT_VAR'], etc A. What causes an Environment Variable set in Apache using the [E=VAR:VAL] flag to get renamed by having "REDIRECT_" appended to the front of the variable name? B. What can I do to make sure I end up with an Environment Variable with an unchanged name so I can access it in PHP as $SERVER['VAR'] without having to resort to checking for variations of the variable name having one of more instances of "REDIRECT" appended to the front of it?

• Programming terms - field, member, properties (C#)

  - by Petr

  Hi, I was trying to find meaning of this terms but especially due to language barrier I was not able to understand what they are used for. I assume that "field" is variable (object too?) in the class while "property" is just an object that returns specific value and cannot contain methods etc. By "member" I understand any object that is declared on the class level. But these are just my assumptions based on commented code samples where some careful programmers used "property region" etc. I would really appreciate if someone could explain it to me.

• The member [class] has no supported translation to SQL

  - by Code Sherpa

  Hi, I am getting the following error: Error Message:The member 'Company.ProductCore.Core.Domain.Account.Email' has no supported translation to SQL. My method looks like this: public Account GetAccountByEmail(string email) { Account account; using (WorkbookDataContext dc = _conn.GetContext()) { account = ( from a in dc.Accounts join em in dc.Emails on a.AccountId equals em.AccountId where a.Email.EmailAddress == email select a).FirstOrDefault(); } return account; } My Account class has a getter / setter that exposes Email: public Email Email { get { return _email; } set { _email = value; } } And my Email is a LINQ object. I have a feeling that the problem is that I am using a LINQ object for me Email property? I am new to LINQ and am not really sure why this is happening. Help appreciated, thanks...

• UDK "Error, Accessing a member of _'s within class through a context expression requires explicit 'O

  I get the following error in the UDK Frontend when I try to make my project: C:\UDK\UDK-2010-03\Development\Src\FixIt\Classes\ZInteraction.uc(58) : Error, Accessing a member of GameUISceneClient's within class through a context expression requires explicit 'Outer' The class ZInteraction extends Interaction.

I am still investigating and I will update as I find out more. edit: Tried fixing the line up as class'UIRoot'.static.GetSceneClient().ConsoleCommand("KEYNAME"@Key); - no change.

• A pointer member variable having different values

  - by Rohan Prabhu

  Ok, to begin with, this is my code: HyperSprite::HyperSprite() { _view = 0; } void HyperSprite::publish(QGraphicsView* view) { _view = view; } void HyperSprite::getKFrame() { if(_view != 0) { qDebug()<<(void*)_view; } } Now, if I call HyperSprite::getKFrame() from within main(), I get the output: 0xbf8ffb84 I have a TCP server, which requires this QGraphicsView* variable. So whenever a new connection is made, HyperSprite::getKFrame() is called. However, whenever I make a connection to my server, this is the output: 0x1e425ff I honestly don't understand this. Shouldn't the value of a member remain same throughout? Why is the pointer value changing? As is obvious, whenever I try to use the _view pointer to access any of its members, a Segmentation Fault occurs. I tried using QSharedPointer, but it also results in the same problem. The data of the QSharedPointer automatically changes. Why is this happening?

• Getting the last member of a group on an intermediary M2M

  - by rh0dium

  If we look at the existing docs, what is the best way to get the last member added? This is similar to this but what I want to do is to be able to do this. group = Group.objects.get(id=1) group.get_last_member_added() #This is by ('-date_added') <Person: FOO> I think the best way is through a manager but how do you do this on an intermediary model? class Person(models.Model): name = models.CharField(max_length=128) def __unicode__(self): return self.name class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(Person, through='Membership') def __unicode__(self): return self.name class Membership(models.Model): person = models.ForeignKey(Person) group = models.ForeignKey(Group) date_joined = models.DateField() invite_reason = models.CharField(max_length=64)

• I having a problem with the mysqli free() member function

  - by neo skosana

  Hi I have code where I connected to the database like so: $db = new mysqli("localhost", "user", "pass", "company"); Now when I query the database like so: //query calls to a stored procedure 'user_info' $result = $db->query("CALL user_info('$instruc', 'c_register', '$eml', '$pass', '')"); //I use the $result This query works well. Now when I try and free that result like so: $result->free(); or $result->close(); It seems like it doesn't do anything because $result is still set. When I try to run another query it gives me this error: Fatal error: Call to a member function fetch_array() on a non-object in... For me to run this other query I have to close the db conection and connect again, then it will work. I want to know if there is a way I could run the other query without having to disconnect and reconnect to the database. thanks in advance.

• About Attributes member of LUID_AND_ATTRIBUTES used in TOKEN_PRIVILEGES structure

  - by Astaroth

  MSDN article, Enabling and Disabling Privileges in C++, provided the a code example to show how to enable or disable a privilege in an access token. I quote the part in questioned: tp.PrivilegeCount = 1; tp.Privileges[0].Luid = luid; if (bEnablePrivilege) tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; else tp.Privileges[0].Attributes = 0; What is the meaning of zero value for Attributes member? According to the documentation of TOKEN_PRIVILEGES structure, the attributes of a privilege can be a combination of the following values: SE_PRIVILEGE_ENABLED  (it is 0x00000002L in WinNT.h) SE_PRIVILEGE_ENABLED_BY_DEFAULT  (it is 0x00000001L in WinNT.h) SE_PRIVILEGE_REMOVED  (it is 0x00000004L in WinNT.h) SE_PRIVILEGE_USED_FOR_ACCESS  (it is 0x80000000L in WinNT.h) So, we don't see any valid constant with a value of zero. I guess, the zero is equal to SE_PRIVILEGE_REMOVED. Anybody here could explain what the zero value really does?

• Member classes versus #includes

  - by ShallowThoughts

  I've recently discovered that it is bad form to have #includes in your header files because anyone who uses your code gets all those extra includes they won't necessarily want. However, for classes that have member variables defined as a type of another class, what's the alternative? For example, I was doing things the following way for the longest time: /* Header file for class myGrades */ #include <vector> //bad #include "classResult.h" //bad class myGrades { vector<classResult> grades; int average; int bestScore; } (Please excuse the fact that this is a highly artificial example) So, if I want to get rid of the #include lines, is there any way I can keep the vector or do I have to approach programming my code in an entirely different way?

• Overcoming the 1024 character limit with setx

  - by Madhur Ahuja

  I am trying to set environment variables using the setx command, such as follows setx PATH "f:\common tools\git\bin;f:\common tools\python\app;f:\common tools\python\app\scripts;f:\common tools\ruby\bin;f:\masm32\bin;F:\Borland\BCC55\Bin;%PATH%" However, I get the following error if the value is more then 1024 characters long: WARNING: The data being saved is truncated to 1024 characters. SUCCESS: Specified value was saved. But some of the paths in the end are not saved in variable, I guess due to character limit as the error suggests.

• How to tell rails to use non-default ruby?

  - by Hamish Downer

  I need two different versions of ruby on a server. The packaged ruby for the packaged puppet to work, and a compiled ruby for a rails web app to work. So basically I want the default ruby to be the ruby from the package, and for rails to use the compiled ruby (in /usr/local/bin/ and /usr/local/lib/ ) I've found references to setting the RUBYPATH and RUBYLIB environment variables, but I'm confused as to where to set them. In .bashrc, .profile, in the apache config somewhere?

• PHP Session variables not passing across pages

  - by mitch

  Common problem, but I'm stumped. Session variables are passing across pages on my local (localhost) deployment, but not on my (www) host. I use a common includes file for each page with this code: $sessionDomain = "/"; @ini_set("session.cookie_path",$sessionDomain); $sessionName = "ccSID".md5('/store/'); session_name($sessionName); session_start(); I confirmed that the session ID cookie (ccSIDxxxxx...) remains the same across pages in my browser, but session variables don't seem to hold up when changing to a page in a different directory.

• Trying to change variables in a singleton using a method

  - by Johnny Cox

  I am trying to use a singleton to store variables that will be used across multiple view controllers. I need to be able to get the variables and also set them. How do I call a method in a singleton to change the variables stored in the singleton. total+=1079; [var setTotal:total]; where var is a static Singleton *var = nil; I need to update the total and send to the setTotal method inside the singleton. But when I do this the setTotal method never gets accessed. The get methods work but the setTotal method does not. Please let me know what should. Below is some of my source code // // Singleton.m // Rolo // // Created by on 6/28/12. // Copyright (c) 2012 Johnny Cox.

• Proper way to set class variables

  - by ensnare

  I'm writing a class to insert users into a database, and before I get too far in, I just want to make sure that my OO approach is clean: class User(object): def setName(self,name): #Do sanity checks on name self._name = name def setPassword(self,password): #Check password length > 6 characters #Encrypt to md5 self._password = password def commit(self): #Commit to database >>u = User() >>u.setName('Jason Martinez') >>u.setPassword('linebreak') >>u.commit() Is this the right approach? Should I declare class variables up top? Should I use a _ in front of all the class variables to make them private? Thanks for helping out.

• Idiomatic ruby for temporary variables within a method

  - by Andrew Grimm

  Within a method, I am using i and j as temporary variables while calculating other variables. What is an idiomatic way of getting rid of i and j once they are no longer needed? Should I use blocks for this purpose? i = positions.first while nucleotide_at_position(i-1) == nucleotide_at_position(i) raise "Assumption violated" if i == 1 i -= 1 end first_nucleotide_position = i j = positions.last while nucleotide_at_position(j+1) == nucleotide_at_position(j) raise "Assumption violated" if j == sequence.length j += 1 end last_nucleotide_position = j Background: I'd like to get rid of i and j once they are no longer needed so that they aren't used by any other code in the method. Gives my code less opportunity to be wrong. I don't know the name of the concept - is it "encapsulation"? The closest concepts I can think of are (warning: links to TV Tropes - do not visit while working) Chekhov'sGun or YouHaveOutlivedYourUsefulness. Another alternative would be to put the code into their own methods, but that may detract from readability.

• How to pass variables using Unittest suite

  - by chrissygormley

  Hello I have test's using unittest. I have a test suite and I am trying to pass variables through into each of the tests. The below code shows the test suite used. class suite(): def suite(self): #Function stores all the modules to be tested modules_to_test = ('testmodule1', 'testmodule2') alltests = unittest.TestSuite() for module in map(__import__, modules_to_test): alltests.addTest(unittest.findTestCases(module)) return alltests It calls tests, I would like to know how to pass variables into the tests from this class. An example test script is below: class TestThis(unittest.TestCase): def runTest(self): assertEqual('1', '1') class TestThisTestSuite(unittest.TestSuite): # Tests to be tested by test suite def makeTestThisTestSuite(): suite = unittest.TestSuite() suite.addTest("TestThis") return suite def suite(): return unittest.makeSuite(TestThis) if __name__ == '__main__': unittest.main() So from the class suite() I would like to enter in a value to change the value that is in assert value. Eg. assertEqual(self.value, '1'). I have tried sys.argv for unittest and it doesn't seem to work. Thanks for any help.

• Why doesn't environment variable get updated in cmd without restart?

  - by John Nevermore

  CMD commands: setx SOMEVARIABLE "newpath" /M setx SOMEVARIABLE "%SOMEVARIABLE%;newpath2" /M Expected output on ECHO %SOMEVARIABLE%: newpath;newpath2 Actual output: %SOMEVARIABLE% Actual value stored (From System Properties-Environment Variables GUI): %SOMEVARIABLE%;newpath2 The only way i can get the expected output is, if i restart the command prompt every time i modify the environment variable. I'm using this command to automate environment variable value appending multiple times during the same process. Why doesn't environment variable get updated in cmd without restart? Is it possible to get the updated value of %SOMEVARIABLE% without restarting the command prompt?

• Unable to view values of variables while debugging

  - by RexM

  I'm trying to debug portions of the current application I'm working on, however when I try and check the value of a property/variable I get the error: Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized. This is just a regular ASP.NET project. In some portions of the application I can view the properties and variables perfectly fine. I haven't figured out what's different about the blocks of code that I can and can not see the values of the variables in.
