call

问题 When I compile the program below, I have an error and a warning in the call Coor_Trans command line as Warning: Line truncated Error: Syntax error in argument list I compile the program several times, but it does not work. Maybe there is something wrong with my call command. program 3D implicit none integer :: i,j,k integer, parameter :: FN=2,FML=5,FMH=5 integer, parameter :: NBE=FN*FML*FMH real, parameter :: pi = 4*atan(1.0) real(kind=4), dimension(1:FN,1:FML+1,1:FMH+1) :: BEXL,BEYL,BEZL

问题 I have a problem with the following code: callBash.py: import subprocess print \"start\" subprocess.call(\"sleep.sh\") print \"end\" sleep.sh: sleep 10 I want the \"end\" to be printed after 10s. (I know that this is a dumb example, I could simply sleep within python, but this simple sleep.sh file was just as a test) 回答1: Making sleep.sh executable and adding shell=True to the parameter list (as suggested in previous answers) works ok. Depending on the search path, you may also need to add ./

问题 I\'m a beginner and I\'ve always read that it\'s bad to repeat code. However, it seems that in order to not do so, you would have to have extra method calls usually. Let\'s say I have the following class public class BinarySearchTree<E extends Comparable<E>>{ private BinaryTree<E> root; private final BinaryTree<E> EMPTY = new BinaryTree<E>(); private int count; private Comparator<E> ordering; public BinarySearchTree(Comparator<E> order){ ordering = order; clear(); } public void clear(){ root

问题 I\'m new to ajax and callback functions, please forgive me if i get the concepts all wrong. Problem: Could i send a callbackfunction as a parameter to another function that will execute the callback? function firstFunction(){ //some code //a callback function is written for $.post() to execute secondFunction(\"var1\",\"var2\",callbackfunction); } function secondFunction(var1, var2, callbackfunction) { params={} if (event != null) params = event + \'&\' + $(form).serialize(); // $.post() will

问题 I try to sort my thoughts about how javascript\'s bind() works. I see that if I do var f = function (a) { ... } var g = f.bind(obj); g(1) then f is called with obj as this and 1 as a . What I thought is g is a wrapper function around f. But when I do var f = function (a) { ... } var g = f.bind(obj); g.call(1) then f is called with 1 as this and a undefined. So it seems g is not just a simple wrapper, but call somehow differentiates between normal and bound functions. One more thing is I

问题 I\'m new to C# and i really need to know how to call/use a string from another method. For example: public void button1_Click(object sender, EventArgs e) { string a = \"help\"; } public void button2_Click(object sender, EventArgs e) { //this is where I need to call the string \"a\" value from button1_click string b = \"I need \"; string c = b + a; } So in this example I need to call string \" a \" defined in function button1_Click() from function button2_Click() Thanks!! 回答1: Usually you'd

问题 This my simplified script: Sub SomeOtherSub(Stattyp As String) \'Daty and the other variables are defined here CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2) End Sub Sub CatSubProduktAreakum(Stattyp As String, starty As Integer) \'some stuff End Sub The call of CatSubProduktAreakum is marked red as a \"syntax error\". I don\'t understand the error. It is a simple sub-routine call with two arguments. Why does VBA not accept the call? 回答1: Try - Call CatSubProduktAreakum

问题 I have the following code. I cannot for the life of me figure it out. I want to call a different sub depending on the value of i . For example, if i = 1 it should call sale_call1 and if i = 2 it should call sale_call2 . Private Sub test_Click() Dim i As String Dim pro As String i = Me.tb1.Value pro = \"sale_call\" + i If i = \"1\" Then Call pro Else Call pro End If End Sub Sub sale_call1() MsgBox \"Hello\" End Sub Sub sale_call2() MsgBox \"goodbye\" End Sub 回答1: Try this Replace Call pro with

问题 I use the Call keyword when calling subs in VB/VBA. I know it\'s optional, but is it better to use it or leave it off? I\'ve always thought it was more explicit, but maybe it\'s just noise. Also, I read this on another forum: Using the Call keyword is faster because it knows that it is not going to return any values, so it doesn\'t need to set up any stackspace to make room for the return value. 回答1: Ah ha. I have long wondered about this and even reading a two inch thick book on VBA

问题 I stumbled onto this neat shortcut for converting a DOM NodeList into a regular array, but I must admit, I don\'t completely understand how it works: [].slice.call(document.querySelectorAll(\'a\'), 0) So it starts with an empty array [] , then slice is used to convert the result of call to a new array yeah? The bit I don\'t understand is the call . How does that convert document.querySelectorAll(\'a\') from a NodeList to a regular array? 回答1: What's happening here is that you call slice() as
