Using CALL for labels in a batch script

由 |▌冷眼眸甩不掉的悲伤 提交于 2019-12-03 16:36:44
问题 When using the CALL command to call a label in a batch script, and you end the sub-routine with GOTO:eof, what happens from there? Does it return back to where the sub-routine's CALL is located? Or does it continue on after the location of the call script? For example: ECHO It's for my college fund. CALL :OMGSUB ECHO *runs away and cries like a little girl* :OMGSUB ECHO Your mom goes to college. GOTO:eof ECHO *picks up jewelry box* After GOTO:eof which line will it echo next? 回答1: Why not

问题 Using VBA with Access 2010, I have a sub: Public Sub setInterest(account As String, dmonth As Integer) ...somecode... End Sub And I am calling it with setInterest("myAccount",3) And I get syntax errors. Modifying the sub to only take one argument and leaving out the 3 gives no errors, the problem is only when I have 2 arguments. 回答1: When using multiple arguments, you can either write: setInterest "myAccount", 3 Or Call setInterest("myAccount", 3) In both examples you can name the arguments:

问题 I'm writing a program in C++ which do some special treatment for all the files in the current directory on Linux OS. So i was thinking of using system calls such as system("ls") to get the list of all files. but how to store it then inside my program ? ( how to redirect the output of ls to let's say a string that i declared in the program ) Thanks 回答1: I suggest you don't call out to ls - do the job properly, using opendir/readdir/closedir to directly read the directory. Code example, print

javascript setTimeout call error

I want to invoke the window.setTimeot function with my custom scope so I use the call method, but there is something wrong. function foo() { this.bar = function() { console.log("keep going"); window.setTimeout.call(this,this.bar,100); } this.bar(); } new foo; under Firefox this prints to the console only 1 line and then nothing, and under google chrome it throws a TypeError . What is the problem in my code? Using call does not help here: it calls setTimeout with your this object, but the callback function itself is still called from the global scope. What you really want to do is something

Calling a Objective C function from C++ Code

I googled around and I find a million results to this subject. But none of the pages helps me. I think that I have a very common problem. I'm playing around with audio programming especially working with audio queues. The purpose of my program does not matter for explaining the problem. But in a nutshell: I get an error when I try to call an objective-c function from c++ code. So here is my code that contains the error: AudioRecorder.h: #import <Foundation/Foundation.h> @interface AudioRecorder : NSObject { } -(void)setup; -(void)startRecording; -(void)endRecording; -(void)playAlarmSound; @end

Python, subprocess, call(), check_call and returncode to find if a command exists

由 我与影子孤独终老i 提交于 2019-12-03 10:58:05
I've figured out how to use call() to get my python script to run a command: import subprocess mycommandline = ['lumberjack', '-sleep all night', '-work all day'] subprocess.call(mycommandline) This works but there's a problem, what if users don't have lumberjack in their command path? It would work if lumberjack was put in the same directory as the python script, but how does the script know it should look for lumberjack? I figured if there was a command-not-found error then lumberjack wouldn't be in the command path, the script could try to figure out what its directory is and look for

Are modern C++ compilers able to avoid calling a const function twice under some conditions?

问题 For instance, if I have this code: class SomeDataProcessor { public: bool calc(const SomeData & d1, const SomeData & d2) const; private: //Some non-mutable, non-static member variables } SomeDataProcessor sdp; SomeData data1; SomeData data2; someObscureFunction(sdp.calc(data1, data2), sdp.calc(data1, data2)); Let's consider the potentially equivalent code: bool b = sdp.calc(data1, data2); someObscureFunction(b,b); For this to be valid, the calc() function should meet some requirements, and
