  • Batch file to open multiple cmd prompts

    - by JHarris
    I am trying to write a batch file that will automate the following manual process: Open a new cmd prompt (prompt1) Run a bat file (b1) Run a program (that will continue to run) Minimize prompt1 Open a new cmd prompt (prompt2) Run a bat file (b1) Run a different program (that will continue to run) Minimize prompt2 I've found ways to open multiple instances of cmd to run different things, but after I've run the first thing (b1), I then need to run a program in that same cmd window. I currently have start /min cmd /k C:\Users\db2admin\python_environment\Scripts\activate.bat start /min cmd /k C:\Users\db2admin\python_environment\Scripts\activate.bat This opens the two windows and runs the bat, great, but now I need to execute another command (running a python file) in each of the cmd windows. How do I send commands to each prompt?

  • Looking for an open source real-time network analysis program

    - by JrSysAdmin
    Can somebody recommend an open source real-time network analysis program? What I'm looking for the program to do is display a graph of bandwidth usage by IP within our internal network that can quickly be viewed any time we need to (typically when we want to quickly find out who is utilizing high amounts of bandwidth and slowing down the network). We ideally simply want to hook up a monitor on the wall of our server room to a system whose NIC will be in permissive mode to log all network activity in a visual manner which can easily be seen and running 24/7. Prefer open source as I do not have a budget for this project and prefer open source projects in general. I'd also prefer for this to be available for CentOS but any linux distro or Windows OS would be acceptable. Thanks!

  • Open file without specifying exact location

    - by person
    Say I have a file in some obscure directory that I want to open and edit. I don't want to do something like this... vim ~/foo/bar/blah/doh/ugh.txt I'd rather be able to say find this file and open it. I know there are commands like locate and find to find a file or directory, but I'm not sure whether these can (or even should) be utilized in what I'm trying to do. Basically, what is the simplest way to open a file with a program w/o specifying its exact location? (In cases where there isn't another file with the same name in the entire system, and cases where there are multiple).

  • How to force "Windows Explorer" to open new folders in the same window

    - by yoshiserry
    I have been searching for an answer to this question for a very long time. I have checked the "open folders in the same window" radio button in the general tab of folder options. I have also been told to uncheck the launch as seperate processes button in the view tab of folder options. I'm thinking some how this must be a registry issue. Anyone know a registry hack that will fix this problem and force windows explorer to open folders in the same window. I'm sick to death of having so many windows open. Im running Windows 7 Ultimate Beta 7100.

  • How to open a EAR/WAR file in windows 7

    - by Calm Storm
    I have a few EAR/WAR files which are Java archives and I would like Windows 7 to open these files the way it opens a file with extension zip. So I open this war file and in the list of softwares available with "Open" I see MS Word, Notepad etc but nothing about CompressedFolderView. I also tried manually specifying the location of exe (I thought this was expand.exe) but that does not work. Does someone know if I can make this work? Or should I use Winzip or some such utilities?

  • Too many files open issue (in CentOS)

    - by Ram
    Recently I ran into this issue in one of our production machines. The actual issue from PHP looked like this: fopen(dberror_20110308.txt): failed to open stream: Too many open files I am running LAMP stack along with memcache in this machine. I also run a couple of Java applications in this machine. While I did increase the limit on the number of files that can be opened to 10000 (from 1024), I would really like to know if there is an easy way to track this (# of files open at any moment) as a metric. I know lsof is a command which will list the file descriptors opened by processes. Wondering if there is any other better (in terms of report) way of tracking this using say, nagios.

  • cannot open file cua in second instance of emacs

    - by Toddeman
    i get the following error when trying to open a second instance of emacs: File error: "Cannot open load file" , "cua" I guess I don't HAVE to open another instance of emacs (that is the beauty after all), I was just trying to keep some things separated (specifically work - like code and debug - and play - like news). Would there be any reason I could not open two instances of emacs if I use cua.el?

  • DirectShow.NET opening any file that Windows Media Player can open

    - by vucetica
    Here is a code snippet from DirectShowNet library, used to open a video file: this.graphBuilder = (IGraphBuilder) new FilterGraph(); // Have the graph builder construct its the appropriate graph automatically hr = this.graphBuilder.RenderFile(filename, null); but the RenderFile method fails. At the same time, Windows Media Player opens the same file nicely. What can be the problem. I got the same behavior without DirectShowNet, but using native C++ code...

  • Feeding PDF through IInternetSession to WebBrowser control - Error

    - by Codesleuth
    As related to my previous question, I have developed a temporary asynchronous pluggable protocol with the specific aim to be able to serve PDF documents directly to a WebBrowser control via a database. I need to do this because my limitations include not being able to access the disk other than IsolatedStorage; and a MemoryStream would be far better for serving up PDF documents that average around 31kb. Unfortunately the code doesn't work, and I'm getting an error from the WebBrowser control (i.e. IE): Unable to download . Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. The line in my code where this occurs is within the following: pOIProtSink.ReportData(BSCF.BSCF_LASTDATANOTIFICATION, (uint)_stream.Length, (uint)_stream.Length); However, if you download the project and run it, you will be able to see the stream is successfully read and passed to the browser, so it seems like there's a problem somewhere to do with the end of reading the data: public uint Read(IntPtr pv, uint cb, out uint pcbRead) { var bytesToRead = Math.Min(cb, _streamBuffer.Length); pcbRead = (uint)_stream.Read(_streamBuffer, 0, (int)bytesToRead); Marshal.Copy(_streamBuffer, 0, pv, (int)pcbRead); return (pcbRead == 0 || pcbRead < cb) ? HRESULT.S_FALSE : HRESULT.S_OK; } Here is the entire sample project: InternetSessionSample.zip (VS2010) I will leave this up for as long as I can to help other people in the future If anyone has any ideas why I might be getting this message and can shed some light on the problem, I would be grateful for the assistance. EDIT: A friend suggested inserting a line that calls the IInternetProtocolSink.ReportProgress with BINDSTATUS_CACHEFILENAMEAVAILABLE pointing at the original file. This prevents it from failing now and shows the PDF in the Adobe Reader control, but means it defeats the purpose of this by having Adobe Reader simply load from the cache file (which I can't provide). See below: pOIProtSink.ReportProgress(BINDSTATUS.BINDSTATUS_CACHEFILENAMEAVAILABLE, @"D:\Visual Studio Solutions\Projects\InternetSessionSample\bin\Debug\sample.pdf"); pOIProtSink.ReportData(BSCF.BSCF_LASTDATANOTIFICATION, (uint)_stream.Length, (uint)_stream.Length); This is progress though, I guess.

  • Close child form if already open

    - by j-t-s
    Hi All How can I go about closing a Child form if it's already open? And if it isn't already open, then open it? Thank you I already have this code, which doesn't work, obviously: Form ibx = new inbox(); if(ibx.Visible) ibx.Dispose(); else ibx.Show(); All that the above does is creates a new form whether or not it's already open.

  • Is my objective possible using WCF (and is it the right way to do things?)

    - by David
    I'm writing some software that modifies a Windows Server's configuration (things like MS-DNS, IIS, parts of the filesystem). My design has a server process that builds an in-memory object graph of the server configuration state and a client which requests this object graph. The server would then serialize the graph, send it to the client (presumably using WCF), the server then makes changes to this graph and sends it back to the server. The server receives the graph and proceeds to make modifications to the server. However I've learned that object-graph serialisation in WCF isn't as simple as I first thought. My objects have a hierarchy and many have parametrised-constructors and immutable properties/fields. There are also numerous collections, arrays, and dictionaries. My understanding of WCF serialisation is that it requires use of either the XmlSerializer or DataContractSerializer, but DCS places restrictions on the design of my object-graph (immutable data seems right-out, it also requires parameter-less constructors). I understand XmlSerializer lets me use my own classes provided they implement ISerializable and have the de-serializer constructor. That is fine by me. I spoke to a friend of mine about this, and he advocates going for a Data Transport Object-only route, where I'd have to maintain a separate DataContract object-graph for the transport of data and re-implement my server objects on the client. Another friend of mine said that because my service only has two operations ("GetServerConfiguration" and "PutServerConfiguration") it might be worthwhile just skipping WCF entirely and implementing my own server that uses Sockets. So my questions are: Has anyone faced a similar problem before and if so, are there better approaches? Is it wise to send an entire object graph to the client for processing? Should I instead break it down so that the client requests a part of the object graph as it needs it and sends only bits that have changed (thus reducing concurrency-related risks?)? If sending the object-graph down is the right way, is WCF the right tool? And if WCF is right, what's the best way to get WCF to serialise my object graph?

  • DGML viewer in VS 2010

    - by Fiona Holder
    I've started messing around with the DGML viewer in VS 2010 (which seems awesome). I know you can create diagrams from your code base. Is there any support for creating a directed graph from whatever I like, or is it purely a code analysis tool? I'd like something along the lines of 'Add Node' or something.

    Hi guys, I am trying to upload a image to a gallery on a facebook fan page, here is my code thus far, $ch = curl_init(); $data = array('type' => 'client_cred', 'client_id' => 'app_id','client_secret'=>'secret_key',' redirect_uri'=>'http://apps.facebook.com/my-application/'); // your connect url here curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/oauth/access_token'); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $rs = curl_exec($ch); curl_close($ch); $ch = curl_init(); $data = explode("=",$rs); $token = $data[1]; $album_id = '1234'; $file= 'http://my.website.com/my-application/sketch.jpg'; $data = array(basename($file) => "@".realpath($file), //filename, where $row['file_location'] is a file hosted on my server "caption" => "test", "aid" => $album_id, //valid aid, as demonstrated above "access_token" => $token ); $ch2 = curl_init(); $url = "https://graph.facebook.com/".$album_id."/photos"; curl_setopt($ch2, CURLOPT_URL, $url); curl_setopt($ch2, CURLOPT_HEADER, false); curl_setopt($ch2, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch2, CURLOPT_RETURNTRANSFER, false); curl_setopt($ch2, CURLOPT_POST, true); curl_setopt($ch2, CURLOPT_POSTFIELDS, $data); $op = curl_exec($ch2); When I echo $token, I seem to be getting the token, but when I run the script, I get this error, {"error":{"type":"OAuthAccessTokenException","message":"An access token is required to request this resource."} , I have NO idea why it is doing this! Basically what I am doing in that code is getting the access token with curl, and then, uploading the photo to my album also via curl, but I keep getting that error! Any help would be appreciated, thank you!

  • Financial Charts / Graphs in Ruby or Python

    - by Eric the Red
    What are my best options for creating a financial open-high-low-close (OHLC) chart in a high level language like Ruby or Python? While there seem to be a lot of options for graphing, I haven't seen any gems or eggs with this kind of chart. http://en.wikipedia.org/wiki/Open-high-low-close_chart (but I don't need the moving average or Bollinger bands) JFreeChart can do this in Java, but I'd like to make my codebase as small and simple as possible. Thanks!

  • How do I define and standardize units in my 3D app?

    - by Omega
    I'm starting to design my object graph for an OpenGL ES 1.1 on Android. What's advisable when it comes to actually drawing my triangles when it comes to controlling their size? Should I store all the vertices in units relative to each other and then multiply them by a value I pass during a draw(GL10 gl)? Would this approach have any impact when it comes time to do frustum culling?
