I have a project I'm working on in Qt creator that requires a third-party library. I want to add the headers to the include path for the project. How do I do this?
I'm looking to find a way to in real-time find the shortest path between nodes in a huge graph. It has hundreds of thousands of vertices and millions of edges. I know this question has been asked before and I guess the answer is to use a breadth-first search, but I'm more interested in to know what software you can use to implement it. For example, it would be totally perfect if it already exist a library (with python bindings!) for performing bfs in undirected graphs.
Hello, i want to ask if there is any way to generate the shortest path from node A to node B
without generating the shortest paths to all the other nodes (stop when node B is in the examined set)
with A-star in QuickGraph.
I want to plug QuickGraph into a game and thus generating all the paths is not allowed from the time
limitations the environment imposes.
Any other suggestions to solve my problem in C# are welcome
Thanks in advance,

Hi,
Given a filename in C, I want to determine whether this file exists and has execute permission on it. All I've got currently is:
if( access( filename, X_OK) != 0 ) {
But this wont search the PATH for files and will also match directories (which I don't want). Could anyone please help?
Can any one guide me on how i can send emails with a return path in ASP.net 3.5 / C# 3.5. I know this was possible few years back but now due to spoofing issues this is not possible. I have been looking on internet but no use. I want the emails if bounced, should reach my bounce mail box, which could be like [email protected].
Please guide. Really stuck ...
Best regards,
Haroon
Hello,
I have:
$page_file_temp = $_SERVER["PHP_SELF"];
which will output: /templates/somename/index.php
I want to extract from that path only "/templates/somename/"
How can I do it?
Thanks!
I'm trying to deploy a Yii webapp into Heroku but, it keep throwing at me a weird error:
Application runtime path "/app/www/protected/runtime" is not valid. Please make sure it is a directory writable by the Web server process.
Makes no sense and I know is something to do with Heroku because in my local machine it works fine.
Does anyone what does this means? what do I need to do in Heroku ti fix this??
Many thanks.
Hello world!
I have an .exe application written in vb.net. When I make shortcuts to the application, say on desktop (or anywhere else) and then click on them I want to programatically get the path to that shortcut, ie. C:/Users/xxx/Desktop/shortcut.lnk.
I want this so I can store the pairs shortcuts : (program + different cmd args).
I was wondering if it would be possible to write a file, not to the local system, but to a connected server or other network path. Would i have to use an external php interface for this or can i entrust this to the AIR framework?
I'm pretty sure that AIR has certain security precautions to prevent this.
Thanks a bunch!
Regards
Hey all
so i wehnt ahead and opened up my .gitconfig file and manually input the
[core]
editor = 'C:/Program Files/Notepad++/notepad++.exe'
which would allow me to execute command:
(im trying to setup my .gitignore list)
"C:/Program Files/Notepad++/notepad++.exe" .gitignore
im JUSt not interested in typing this out every time that i need to make a file
SO ive heard something about editing PATH to allow me to replace the above with something like:
npp .gitignore
any help would be aprpeciated!
Hi,
I want to write a new file with the Java FileWriter. I use it like this:
FileWriter newJsp = new FileWriter("C:\\user\Desktop\dir1\dir2\filename.txt");
Now the dir1 and dir2 currently don't exist. I want Java to create them automatically if they aren't already there. Actually Java should set up the whole file path if not already existing.
How can I achieve this?
When I try to use "%~dp0" in batch files stored on remote servers, sometimes it takes a good 45 seconds for the path to resolve! I have a fast connection and doing other things with these remote servers is quick.
Is this normal? Is there any way around it? Any help would be greatly appreciated.
Will data traffic go through the host application program or will be dealt remotely in scenarios where C#'s File.Copy is used:
File.Copy(@"\\SERVER13\LOL\ROFL.txt", @"\\SERVER13\ROFL.txt")
Cheers n thx!
I have a Dynamic Web Project having a flat file (or say text file). I have created a servlet in which I need to use this file.
My code is as following:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// String resource = request.getParameter ("json") ;
if ( resource != null && !resource.equals ( "" ) ) {
//use getResourceAsStream ( ) to properly get the file.
InputStream is = getServletContext ().getResourceAsStream ("rateJSON") ;
if ( is != null ) { // the resource exists
response.setContentType("application/json");
response.setHeader("Pragma", "No-cache");
response.setDateHeader("Expires", 0);
response.setHeader("Cache-Control", "no-cache");
StringWriter sw = new StringWriter ( ) ;
for ( int c = is.read ( ) ; c != -1; c = is.read ( ) ) {
sw.write ( c ) ;
}
PrintWriter out = response.getWriter();
out.print (sw.toString ()) ;
out.flush();
}
}
}
The problem is that the InputStream is has null value.
I'm not sure how to get the correct relative path.
I'm using JBOSS as the app server.
I have added the resource file in the WebContent directory of a Dynamic Web Project.
As a different approch, I tried this:
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
ServletConfig config = getServletConfig();
String contextName = config.getInitParameter("ApplicationName");
System.out.println("context name"+ contextName);
String contextPath = config.getServletContext().getRealPath(contextName);
System.out.println("context Path"+contextPath);
//contextPath = contextPath.substring(0, contextPath.indexOf(contextName));
contextPath += "\\rateJSON.txt";
System.out.println(contextPath);
String resource = request.getParameter ("json") ;
System.out.println("Hi there1"+resource);
if ( resource != null && !resource.equals ( "" ) ) {
System.out.println("Hi there");
//use getResourceAsStream ( ) to properly get the file.
//InputStream is = getServletContext ().getResourceAsStream (resource) ;
InputStream is = getServletConfig().getServletContext().getResourceAsStream(contextPath);
if ( is != null ) { // the resource exists
System.out.println("Hi there2");
response.setContentType("application/json");
response.setHeader("Pragma", "No-cache");
response.setDateHeader("Expires", 0);
response.setHeader("Cache-Control", "no-cache");
StringWriter sw = new StringWriter ( );
for ( int c = is.read ( ) ; c != -1; c = is.read ( ) ) {
sw.write ( c ) ;
System.out.println(c);
}
PrintWriter out = response.getWriter();
out.print (sw.toString ()) ;
System.out.println(sw.toString());
out.flush();
}
}
}
The value of contextPath is now: C:\JBOSS\jboss-5.0.1.GA\server\default\tmp\4p72206b-uo5r7k-g0vn9pof-1-g0vsh0o9-b7\Nationwide.war\WEB-INF\rateJSON
But at this location the rateJSON file is not there? It seems JBOSS is not putting this file in the App.war or doesn't deploy it???
Could someone please help me?
So, my path variable (System-Adv Settings-Env Vars-System-PATH) is set to:

Although, obviously, without the newlines.
Notice the lines containing PathWithSpaces - the first has no spaces, the second has a space, and the third has a space followed by a parenthesis.
Now, notice the output of this batch file:

or specifically the line:

So, what is this bullshit?
Specifically:
Directory in path that is properly
escaped with quotes, but with no
spaces = fine
Directory in path that
is properly escaped with quotes, and
has spaces but no parenthesis = fine
Directory in path that is properly

Whats going on here? How can I fix this? I'll probably resort to a junction point to let my tools still work as workaround, but if you have any insight into this, please let me know :)
Hi,
suppose I have 10 points. I know the distance between each point.
I need to find the shortest possible route passing trough all points.
I have tried a couple of algorithms (Dijkstra, Floyd Warshall,...) and the all give me the shortest path between start and end, but they don't make a route with all points on it.
Permutations work fine, but they are to resource expensive.
What algorithms can you advise me to look into for this problem? Or is there a documented way to do this with the above mentioned algorithms?
Tnx
Jeroen
Where do you guys store 3rd party (and your own) components?
Do you keep separate copies per Delphi version?
For years I've been using c:\program files\borland\delphi7\lib\, even for Delphi 2006, 2007, 2009 and 2010, like this:
c:\program files\borland\delphi7\lib\AggPas\
c:\program files\borland\delphi7\lib\DeHL\
c:\program files\borland\delphi7\lib\DevExpress\
c:\program files\borland\delphi7\lib\FastCode\
c:\program files\borland\delphi7\lib\FastMM\
c:\program files\borland\delphi7\lib\Fundamentals\
c:\program files\borland\delphi7\lib\Graphics32\
c:\program files\borland\delphi7\lib\JCL\
c:\program files\borland\delphi7\lib\JVCL\
c:\program files\borland\delphi7\lib\OmniThread\
c:\program files\borland\delphi7\lib\Raize\
c:\program files\borland\delphi7\lib\TeeChartPro\
c:\program files\borland\delphi7\lib\TurboPower\
c:\program files\borland\delphi7\lib\VirtualTreeView\
c:\program files\borland\delphi7\lib\Zeos\
However, nowadays I don't even use Delphi7 anymore (what can it do that 2010 can't?), so this path doesn't make much sense anymore.
I'm about to install windows7 on my home machine, so I'm thinking on something like this:
c:\src\DelphiLib\
Any better ideas?
config.php put at the root level, this file will be included in any pages.
Then at config.php
<?php
define( 'ROOT_DIR', dirname(__FILE__) );
?>
So at all other pages from different sub/a.php , sub/sub/b.php directories, when I want to include a specific file in specific location, I just need to
include( ROOT_DIR.'/include/functions.php' );
In windows server, the ROOT_DIR bring the value to C:/inetpub/vhosts/domain.com
Is this a good/secure way?
It seems like via this way, when I move the b.php to other upper level folder, I don't need to do any changes to the include file path, which is good for maintenance.
Any cons? Like SEO wise, or any other reason...
What you guys think.
Hi,
I have a small library of a few shortest path search algorithms. They were developed for simple undirected graphs (the normal representation - vertices and edges). Now I'd like to somehow apply them on a bit different scenario - where the maps are represented as 2-dimensional shapes, connected by shared edges (edges of the polygons, that is). In this scenario, the search can start/end either at a map object or some point (x,y). What would be the best approach? Try to apply the algorithms onto shapes? or try to extract a 'normal' graph out of the shapes (I have preprocessing time available)? Any advice would be much appreciated, as I'm really not sure which way to go, and I don't have enough time (and skill) to explore many options...
Thanks a lot
If you install the latest java 1.6 jdk, without installing the public jre option, you end up having two \bin dirs with java.exe:
%JAVA_HOME%\jre\bin
%JAVA_HOME%\bin
if you compare those dirs, there are a few files that are identical (java.exe etc), and a bunch that are either in one or the other. So far I used to add %JAVA_HOME%\bin to my Path environment var, but now I am wondering, does it make a difference? Is there any side effect to choose one or the other?
And would not be much cleaner if the installation had only one java.exe and \bin folder?
Lets say I have an application with a structure such as:
System
set date
set name
set something
Other
set death ray target
calibrate
and I want to have "back" and "next" buttons on a page. The catch is, if you're going in via the "wizard", I want the nav path to be something like "set name" - "set death ray target" - "set name". If you go via the Advanced options menu, I want to just iterate options... "set date" - "set name" - "set something" - "set death ray target" - calibrate.
So far, I'm thinking I have to use different URIs, but that's that. Any ideia how this could be done?
Thanks.
xcopy /e /q ".\dlls\*.*" "%programfiles(x86)%\foo" >> TEMP
xcopy /e /q dlls "%programfiles(x86)%\foo" >> TEMP
xcopy /e /q ".\dlls" "%programfiles(x86)%\foo" >> TEMP
All of the above work on two of my machines (windows 7 64bit).
But on two peers' laptops (windows 7 64 bit and windows 8 64bit) they return
file dlls not found
or (in the case of the first one)
file *.* not found
Can someone shed some light here? The only difference I can see between the machines is possibly permissions. But I don't see how that would affect xcopy's ability to recognize a local path.
In school I am part of a team of four working to create a GUI to translate the paper records of a made-up company and their functionality to a digital format. We're using an ASP.NET website for this purpose.
Basically we use stored procedures and C# classes to represent the database. The folder we're using for the project contains the site and the libraries in separate folders. If I try to open the site from the folder containing both these elements the site will not run. I want to know if there is some way I can set up a relative path to the database in the Settings.Settings.cs file (or by some other means) of my libraries so I don't have to constantly change the database location for the connection string value every time we move the project.
I suppose I should also mention that the database is in an App_Data folder.
Hello,
I'm trying to read a css file with the Resources provided by Spring.
My application looks like this:
src
src/com herer my classes inside packages
WebContent
WebContent/resources/style/myCSS.css -- the css I want to read
WebContent/WEB-INF -- here is my application-context.xml
I can get the css and read it by doing something like this:
UrlResource file = new UrlResource("http://localhost:8080/myApp/resources/style/myCSS.css");
but it depends on the server and aplication names.
I've tried to do it by other implementations of Resource Interface, but the file is not found cause I can't find out how to wite the path. I've tried with this:
FileSystemResource file = new FileSystemResource("/WebContent/resources/style/myCSS.css");
I also tried with wildcards, but it doesn't find the file either.
ApplicationContext ctx = new FileSystemXmlApplicationContext("classpath*:/WEB-INF/application-context-core.xml");
Resource file = ctx.getResource("file:**/myCSS.css");
How should I write the path to get the css.
Thanks.
