How can I find the width of a command line window from a GNU C++-program ? I'll use this information to display a progress bar when copying files, so I need to know the width to be able to display the progress bar correctly.

I am trying to create a gui that will interact with an existing external console application, e.g. the user only changes information in text boxes or radio buttons and that will prompt the VB.net program to sumbit a certain set of commands. I will create a folder for the end user that has only two programs in it, the VB.exe and the OtherProgram.exe. I have tried using ProcessStart with SendKeys to send information to the terminal with limited success (errors include multiple instances opening, entering "ttttttteeeeeeexxxxxxtttttt" instead of "text") and also Shell(OtherProgram.exe) and SendKeys with the same result. I am …

Is it possible to have an optional command-line argument? For example, I want: [CODE]script.py -b[/CODE] to behave differently than [CODE]script.py -b 6[/CODE] In script.py, an enumerated -b argument specifies a behaviour, but if no argument is specified, a behaviour is randomly chosen. Here is my experimentation with getopt. With an enumerated argument, this works perfectly: [CODE]>>> import getopt >>> my_args = '-a -b BeastieBoys -c InterGalacticPlanetary'.split() >>> my_args ['-a', '-b', 'BeastieBoys', '-c', 'InterGalacticPlanetary'] >>> optlist, args = getopt.getopt(my_args, 'ab:c:') >>> optlist [('-a', ''), ('-b', 'BeastieBoys'), ('-c', 'InterGalacticPlanetary')][/CODE] But if an argument is not specified for -b, then the next opt …

I want to parse command line arguments. Say someone gives me ./progname param2 [-price=50] [-size=10] [-weight=16] [-height=7] Square bracketed items are optional. Either none or exactly two of -price, -size, -weight, and -height can be specified. If none of them are specified, it should be taking default values for price & weight. I have already found how to decode for argv[0], argv[1]. But for argv[2] beyond till these optional items end, i am not able to parse. I require code that can help me or some sort of syntax if complete code not possible. Thanks.

I need to run several commands more than 400 times for a mass number of files. Therefore, I'm trying to incorporate the commands in to a python script to automate the processes. Even though the commands run successfully in the the windows command prompt (I have manually tested the commands), they do not run successfully in python using os.system module as below. [CODE] import os os.system('command') [/CODE] For some commands such as 'cd' or 'dir', I get 0 for the exit code. For other commands I am getting 1 or 2 for the exit code (sometimes I get both). As …

Hi, I just started programming in Java, and now i tried to compile a file with the Mac Terminal (Command-line), but it did only give me an error which i couldn't explain, because this code did work in Eclipse compiler. Here's my code: [code="java"] class HelloWorldApp { public static void main (string [] args) { System.out.println("Hello World!"); // Display the string. } } [/code] (Yes, i can do better, i just wrote this to see if i could compile something with the command-line.) and this is what i did: Last login: Fri Sep 2 18:06:02 on ttyp1 Welcome to Darwin! …

Is it possible to set the maximum memory windows can use via command line. This option is very easily changed through the GUI as seen [URL="http://www.sevenforums.com/tutorials/66482-memory-set-maximum-amount-used-windows-7-a.html"]in this tutorial[/URL] I can't seem to find any examples online without running into something similar to the tutorial provided above. My target device is windows 7. Thanks
