  • Variable type for Application on Time Events [on hold]

    - by user2931226
    Been Trying to figure out how to go about setting a Variable for some Application On Time events, But still not confident to do it. These events (Macro's) get called by another Macro then they wait for 10 - 20 minutes, then they don't Run. So have read that (EarliestTime argument) should be assigned to a variable to store it other wise it looses it when other things are running Help appreciated Thanks Sub settimers() Application.OnTime TimeValue(Range("$X$9").Text), "StartBlink" Application.OnTime TimeValue(Range("$W$11").Text), "StopBlink" End Sub

  • Why do we use to talk about addresses and memory of variable in C?

    - by user2720323
    Why do we use to talk about addresses and memory of variable in C, where in other languages (like in Java, .Net etc) we do not talk about variable address and memory in a program, we will directly use the variables. But in C Language we are listening the word address and memory. How to explain this? I hope C is high level language designed over the assembly language. So C is a thin layer over assembly language (in assembly language we will use memory locations to store a variable and track a variable). But in other languages these addresses and memory related things are wrapped in that specific language, so that we will not listen these words.

  • Variable scope and the 'using' statement in .NET

    - by pete the pagan-gerbil
    If a variable is at class level (ie, private MyDataAccessClass _dataAccess;, can it be used as part of a using statement within the methods of that class to dispose of it correctly? Is it wise to use this method, or is it better to always declare a new variable with a using statement (ie, using (MyDataAccessClass dataAccess = new MyDataAccessClass()) instead of using (_dataAccess = new MyDataAccessClass()))?

  • Quetion regarding local and global variable in javascript

    - by caramel1991
    Today,I started to code a page that prompt the user to choose their PC spec,and the code is as follow <html> <title>Computer Specification Chooser</title> <head> <script type="text/javascript"> var compSpec = document.compChooser; function processorUnavailable_onclick() { alert("Sorry that processor speed is currently unavailable"); compSpec.processor[2].checked = true; } </script> </head> <body> <form name="compChooser"> <p>Tick all components you wan included on your computer</p> <p> DVD-ROM <input type="checkbox" name="chkDVD" value="DVD-ROM" /> <br /> CD-ROM <input type="checkbox" name="chkCD" value="CD-ROM" /> <br /> Zip Drive <input type="checkbox" name="chkZIP" value="ZIP DRIVE" /> </p> <p> Select the processor speed you require <br /> <input type="radio" name="processor" value="3.8" /> 3.8 GHZ <input type="radio" name="processor" value="4.8" onclick="processorUnavailable_onclick()" /> 4.8 GHZ <input type="radio" name="processor" value="6" /> 6 GHZ </p> <input type="button" name="btnCheck" value="Check Form" /> </form> </body> </html> The problem I'm facing is on the function that I've tie to the event handler,when I try to choose the radio button of the processor value 4.8 GHZ,yes it alert me with the message inside the function,but after that,it doest not execute the next statement inside the function,that is to check the next processor value 6 GHZ,I've try my effort to change it and test on it,and find out when I set the var compSpec = document.compChooser as a local variable inside the function instead of a global variable,the next statement could be executed.But I thought for a global variable,it is accessible in everywhere on the page and also inside a function.But why now I can't accesses it inside my function??Any idea??Besides,I stumble upon a weird article while googling,it says that when a global variable is created,it is added to window object.I just curious why this happen??And what's the benefits and uses of it??THANK YOU

  • Using Variables for Class Names in Python?

    - by Sam McAfee
    I want to know how to use variables for objects and function names in Python. In PHP, you can do this: $className = "MyClass"; $newObject = new $className(); How do you do this sort of thing in Python? Or, am I totally not appreciating some fundamental difference with Python, and if so, what is it?

  • CopyFileEx and 8.3 file names

    - by Lobuno
    Suppose you have 2 files in the same directory: New File Name.txt and NewFil~1.txt If you use CopyFileEx to copy both files to the same destination, maintaining the same names, you will end up having only ONE file (the second one replaces the first one) which can be sometimes not a good thing. Any workaround for this behavior?

  • Troubles with a PHP session variable after form submission

    - by Psyche
    Hello, I'm setting a PHP session variable with a success message for a HTML form that I'm submitting. If there are no form errors, I redirect to the same page (using header()) and display the message from the session variable. Everything is fine until here, but if I access that page again after submission, the message is still there. Is it possible to make it appear only when I redirect after a successful submit? Thank you.

  • Perl ENV variable contains newline and tab

    - by Michael
    Say I have an environment variable myvar myvar=\tapple\n when the following command will print out this variable perl -e 'print "$ENV{myvar}"' I will literally have \tapple\n, however, I want those control chars to be evaluated and not escaped. How would I achieve it? In the real world $ENV residing in substitution, but I hope the answer will cover that.

  • Setting Environment Variable for Tomcat 6 Servlet

    - by amaevis
    I'm using Ubuntu's default installation of Tomcat 6. I'm deploying a ROOT.war, and trying to set an environment variable specific to it, i.e. accessible from System.getenv() in the Servlet.init(config). According to the docs (http://tomcat.apache.org/tomcat-6.0-doc/config/context.html), I can specify this in a Context element in conf/Catalina/localhost/ROOT.xml. I've created that with these contents: <Context> <Environment name="FOO" value="bar" type="java.lang.String" override="false"/> </Context> And I've deployed the webapp as usual, i.e. to webapps/ROOT.war. Server.getenv("FOO") in the Servlet.init(config) still returns null. What am I missing?

  • An object reference is required for the non-static field, method, or property using global variable

    - by Jose Cardama
    Hello Iam working in a global int in which a variable will be used later. I've made the global variable like this: class Foo { public static int stream = Bass.BASS_StreamCreateFile(path1.Text, 0, 0, BASSFlag.BASS_DEFAULT); } which will be later called like this: Foo.stream and it can also contain more then 1 stream for example stream20,30,etc... The problem here is that it returns me this error: "An object reference is required for the non-static field, method, or property" where I call the text in path1.Text How do I fix this?

  • Where to export a truly global environment variable?

    - by Socio
    I want to set an environment variable that will be visible to all processes launched by Upstart. This is on a CentOS system, but I presume the same applies to Ubuntu given that they both use Upstart. Somewhere in /etc/init/ perhaps? Note that adding it in /etc/profile.d only applies to login shells. I want all processes (e.g cron, rc.local, etc) to see it. Obviously I'd prefer not to edit existing sys config files if it can be avoided.

  • Do there exist programming languages where a variable can truly know its own name?

    - by Job
    In PHP and Python one can iterate over the local variables and, if there is only once choice where the value matches, you could say that you know what the variable's name is, but this does not always work. Machine code does not have variable names. C compiles to assembly and does not have any native reflection capabilities, so it would not know it's name. (Edit: per Anton's answer the pre-processor can know the variable's name). Do there exist programming languages where a variable would know it's name? It gets tricky if you do something like b = a and b does not become a copy of a but a reference to the same place. EDIT: Why in the world would you want this? I can think of one example: error checking that can survive automatic refactoring. Consider this C# snippet: private void CheckEnumStr(string paramName, string paramValue) { if (paramName != "pony" && paramName != "horse") { string exceptionMessage = String.Format( "Unexpected value '{0}' of the parameter named '{1}'.", paramValue, paramName); throw new ArgumentException(exceptionMessage); } } ... CheckEnumStr("a", a); // Var 'a' does not know its name - this will not survive naive auto-refactoring There are other libraries provided by Microsoft and others that allow to check for errors (sorry the names have escaped me). I have seen one library which with the help of closures/lambdas can accomplish error checking that can survive refactoring, but it does not feel idiomatic. This would be one reason why I might want a language where a variable knows its name.

  • Save all file names in a directory to a vector

    - by Bobby
    I need to save all ".xml" file names in a directory to a vector. To make a long story short, I cannot use the dirent API. It seems as if C++ does not have any concept of "directories". Once I have the filenames in a vector, I can iterate through and "fopen" these files. Is there an easy way to get these filenames at runtime?

  • How to free static member variable in C++?

    - by user299831
    Can anybody explain how to free memory of a static member Variable? In my understanding it can only be freed if all the instances of the class are destroyed. I am a little bit helpless at this point... Some Code to explain it: class ball { private: static SDL_Surface *ball_image; }; //FIXME: how to free static Variable? SDL_Surface* ball::ball_image = SDL_LoadBMP("ball.bmp");

  • Dynamic Data - Make Friendly Column Names?

    - by davemackey
    I've created a Dynamic Data project with an Entity Framework model. It works nicely. But, right now it shows all my database tables with the db column names - which aren't always the most friendly (e.g. address_line_1). How can I got about giving these more friendly column titles that will display to the end user?
