  • I installed XAMPP in a virtual drive and now I can't run its services. Why?

    - by Haris
    Hi, The description is quite long. Please spend some time to read it. ^:)^ I have an old PHP application and I'm trying to test and debug it. Unfortunately, the application uses important data so I can't just click this and that. Now, what I'm trying to do is create a copy of the application in a different computer. From now on, I will call the computer running my original PHP application as 'Computer A' and the computer which I'm going to use to run the copy of the application as 'Computer B'. To prevent missing link problems since the application contains static paths, such in images or tags, I have to copy all files and folder related to my PHP application from Computer A to the same path in Computer B. Unfortunately, Computer B only has drive C while Computer A has drive D and the files of my PHP application is located in 'D:\xampp\htdocs' in Computer A. OK, now I have to create drive D in computer B. At first, I tried to create a second partition in Computer B by using PowerQuest Partition Magic 8, but somehow Partition Magic doesn't run in Computer B. I have tried to reinstall it but it still doesn't run. So, another alternative is to create a virtual drive. That is what I did. I created a virtual drive by running the 'subst' command in Command Prompt. The virtual drive is D and it refers to a directory, which is 'C:\Virtual'. After I have drive D in Computer B, I installed XAMPP there. The installation was successful. Now, I also have 'D:\xampp\htdocs' in Computer B. However, when I ran the Apache, MySQL, or Filezilla service, I receive an error message "Error 3: The system cannot find the file specified.". In Computer B, there is no IIS or process using the port 80. What should I do? Please help me. Many thanks in advance, Haris

  • How do I browse a Websphere MQ message without removing it?

    - by jmgant
    I'm writing a .NET Windows Forms application that will post a message to a Websphere MQ queue and then poll a different queue for a response. If a response is returned, the application will partially process the response in real time. But the response needs to stay in the queue so that a daily batch job, which also reads from the response queue, can do the rest of the processing. I've gotten as far as reading the message. What I haven't been able to figure out is how to read it without removing it. Here's what I've got so far. I'm an MQ newbie, so any suggestions will be appreciated. And feel free to respond in C#. Public Function GetMessage(ByVal msgID As String) As MQMessage Dim q = ConnectToResponseQueue() Dim msg As New MQMessage() Dim getOpts As New MQGetMessageOptions() Dim runThru = Now.AddMilliseconds(CInt(ConfigurationManager.AppSettings("responseTimeoutMS"))) System.Threading.Thread.Sleep(1000) 'Wait for one second before checking for the first response' While True Try q.Get(msg, getOpts) Return msg Catch ex As MQException When ex.Reason = MQC.MQRC_NO_MSG_AVAILABLE If Now > runThru Then Throw ex System.Threading.Thread.Sleep(3000) Finally q.Close() End Try End While Return Nothing 'Should never reach here' End Function NOTE: I haven't verified that my code actually removes the message. But that's how I understand MQ to work, and that appears to be what's happening. Please correct me if that's not the default behavior.

  • How to Avoid PHP Object Nesting/Creation Limit?

    - by Will Shaver
    I've got a handmade ORM in PHP that seems to be bumping up against an object limit and causing php to crash. Here's a simple script that will cause crashes: <? class Bob { protected $parent; public function Bob($parent) { $this->parent = $parent; } public function __toString() { if($this->parent) return (string) "x " . $this->parent; return "top"; } } $bobs = array(); for($i = 1; $i < 40000; $i++) { $bobs[] = new Bob($bobs[$1 -1]); } ?> Even running this from the command line will cause issues. Some boxes take more than 40,000 objects. I've tried it on Linux/Appache (fail) but my app runs on IIS/FastCGI. On FastCGI this causes the famous "The FastCGI process exited unexpectedly" error. Obviously 20k objects is a bit high, but it crashes with far fewer objects if they have data and nested complexity. Fast CGI isn't the issue - I've tried running it from the command line. I've tried setting the memory to something really high - 6,000MB and to something really low - 24MB. If I set it low enough I'll get the "allocated memory size xxx bytes exhausted" error. I'm thinking that it has to do with the number of functions that are called - some kind of nesting prevention. I didn't think that my ORM's nesting was that complicated but perhaps it is. I've got some pretty clear cases where if I load just ONE more object it dies, but loads in under 3 seconds if it works.

  • The worker processcalls OpenSubKey but returns null by accessing Remote Registry service.

    - by Cary
    My web server is deployed in IIS 6. The web server starts the Remote Registry service in the remote machine successfully by creating a process to run some remote operation commands. This first line runs successfully. But the second line returns null. #1 RegistryKey remoteRegKey = RegistryKey.OpenRemoteBaseKey(RegistryHive.LocalMachine, "139.24.185.27"); #2 RegistryKey targetKey = remoteRegKey.OpenSubKey(@"SOFTWARE\Wow6432Node\XXXX\XXXX\Config\Modality", true); I tried to find the reason from MSDN. It tells only one case it would return null. The case is when the subkey does not exist. If it has not enough permission, it will throw exception. But the subkey really exists. I change another machine to debug my code with Visual Studio 2008. It can run two lines successfully. If it has enough permission, it should not only can open the LocalMachine, but also can open any of its subkeys. I am quite confusing about this.

  • Copy SQL Server data from one server to another on a schedule

    - by rwmnau
    I have a pair of SQL Servers at different webhosts, and I'm looking for a way to periodically update the one server using the other. Here's what I'm looking for: As automated as possible - ideally, without any involvement on my part once it's set up. Pushes a number of databases, in their entirely (including any schema changes) from one server to the other Freely allows changes on the source server without breaking my process. For this reason, I don't want to use replication, as I'd have to break it every time there's an update on the source, and then recreate the publication and subscription One database is about 4GB in size and contains binary data. I'm not sure if there's a way to export this to a script, but it would be a mammoth file if I did. Originally, I was thinking of writing something that takes a scheduled full backup of each database, FTPs the backups from one server to the other once they're done, and then the new server picks it up and restores it. The only downside I can see to this is that there's no way to know that the backups are done before starting to transfer them - can these backups be done synchronously? Also, the server being refreshes is our test server, so if there's some downtime involved in moving the data, that's fine. Does anybody out there have a better idea, or is what I'm currently considering the best non-replication way to go? Thanks for your help, everybody. UPDATE: I ended up designing a custom solution to get this done using BAT files, 7Zip,command line FTP, and OSQL, so it runs in a completely automatic way and aggregates the data from a dozen servers across the country. I've detailed the steps in a blog entry. Thanks for all your input!

  • Sending basic authentication information via form

    - by VolatileStorm
    I am working on a site that currently uses a basic authentication dialog box login system, that is the type of dialog that you get if you go here: http://www.dur.ac.uk/vm.boatclub/password/index.php I did not set this system up and am not in a position to easily/quickly work around it, but it DOES work. The issue however is that the dialog box is not very helpful in telling you what login information you have to use (that is which username and password combination), and so I would like to replace it with a form. I had been thinking that this wasn't possible but I wanted to ask in order to find out. Is it possible to set up an HTML form that sends the data to the server such that it accepts it in the same way that it would using this dialog box? Alternatively is it possible to set up a PHP script that would take normal form data and process it somehow passing it to the server such that it logs in? Edit: After being told that this is basic authentication I went around and have managed to find a way that works and keeps the user persistently logged in. However, this does not work in internet explorer. The solution was simply to redirect the user to: http://username:[email protected]/vm.boatclub/password/index.php But Internet Explorer removed it due to phishing uses about 3 years ago. Is there a way to use javascript to get the browser to access the site in this way? Or will I have to simply change my UI?

  • Python access an object byref / Need tagging

    - by Aaron C. de Bruyn
    I need to suck data from stdin and create a object. The incoming data is between 5 and 10 lines long. Each line has a process number and either an IP address or a hash. For example: pid=123 ip=192.168.0.1 - some data pid=123 hash=ABCDEF0123 - more data hash=ABCDEF123 - More data ip=192.168.0.1 - even more data I need to put this data into a class like: class MyData(): pid = None hash = None ip = None lines = [] I need to be able to look up the object by IP, HASH, or PID. The tough part is that there are multiple streams of data intermixed coming from stdin. (There could be hundreds or thousands of processes writing data at the same time.) I have regular expressions pulling out the PID, IP, and HASH that I need, but how can I access the object by any of those values? My thought was to do something like this: myarray = {} for each line in sys.stdin.readlines(): if pid and ip: #If we can get a PID out of the line myarray[pid] = MyData().pid = pid #Create a new MyData object, assign the PID, and stick it in myarray accessible by PID. myarray[pid].ip = ip #Add the IP address to the new object myarray[pid].lines.append(data) #Append the data myarray[ip] = myarray[pid] #Take the object by PID and create a key from the IP. <snip>do something similar for pid and hash, hash and ip, etc...</snip> This gives my an array with two keys (a PID and an IP) and they both point to the same object. But on the next iteration of the loop, if I find (for example) an IP and HASH and do: myarray[hash] = myarray[ip] The following is False: myarray[hash] == myarray[ip] Hopefully that was clear. I hate to admit that waaay back in the VB days, I remember being able handle objects byref instead of byval. Is there something similar in Python? Or am I just approaching this wrong?

  • ASP.NET Memory Usage in IIS is FAR greater than in DevEnv. Is this normal?

    - by Tom
    Greetings! I have an ASP.NET app that scrapes data from a handful of external pages, parses the relevant bits and displays them in a table. Total data retrieved is 3-4MB and the resulting page is about 1MB. I am using synchronous WebRequest GetResponse for the retrieval, but the same problem existed using an asynchronous BeginGetResponse/EndGetResponse process. There is no database access, no session storage, no caching, but an in-memory list of about 100 objects (total 1MB of data), plus a good amount of AJAX (AjaxControlToolkit). This issue appears on the very first run of the app, even if I have restarted IIS. The issue: When I run the app on my dev computer, the maximum commit charge is about 1.5GB. The biggest user, measured by Task Manager's VM Size, is WebDev.WebServer.exe (600MB). The app runs perfectly. When I run it on my rent-a-server (IIS 7.5, 1GB RAM), the maximum commit charge is over 3.8GB. The biggest user is w3wp.exe at 2.7GB. IIS grinds to a halt and spits out a timed-out error page. Given my limited server budget and the hope of having multiple simultaneous users, I'm kind of in a panic. Is this normal? If I bump the server RAM up to 4GB, will that be enough? Will multiple users require even more memory? Could the culprit be AJAX or the list of objects? Thanks for any insight you can provide.

  • Is it possible to store pointers in shared memory without using offsets?

    - by Joseph Garvin
    When using shared memory, each process may mmap the shared region into a different area of their address space. This means that when storing pointers within the shared region, you need to store them as offsets of the start of the shared region. Unfortunately, this complicates use of atomic instructions (e.g. if you're trying to write a lock free algorithm). For example, say you have a bunch of reference counted nodes in shared memory, created by a single writer. The writer periodically atomically updates a pointer 'p' to point to a valid node with positive reference count. Readers want to atomically write to 'p' because it points to the beginning of a node (a struct) whose first element is a reference count. Since p always points to a valid node, incrementing the ref count is safe, and makes it safe to dereference 'p' and access other members. However, this all only works when everything is in the same address space. If the nodes and the 'p' pointer are stored in shared memory, then clients suffer a race condition: x = read p y = x + offset Increment refcount at y During step 2, p may change and x may no longer point to a valid node. The only workaround I can think of is somehow forcing all processes to agree on where to map the shared memory, so that real pointers rather than offsets can be stored in the mmap'd region. Is there any way to do that? I see MAP_FIXED in the mmap documentation, but I don't know how I could pick an address that would be safe.

  • Why does this gstreamer pipeline stall ?

    - by timday
    I've been playing around with gstreamer pipelines using gst-launch. I don't have any problems if I just want to process audio or video separately (to separate files, or to alsasink/ximagesink), but I'm confused by what I need to do to mux the streams back together using, say avimux. This gst-launch-0.10 filesrc location=MVI_2034.AVI ! decodebin name=dec \ dec. ! queue ! audioconvert ! 'audio/x-raw-int,rate=44100,channels=1' ! queue ! mux. \ dec. ! queue ! videoflip 1 ! ffmpegcolorspace ! jpegenc ! queue ! mux. \ avimux name=mux ! filesink location=out.avi just outputs Setting pipeline to PAUSED ... Pipeline is PREROLLING ... and then stalls indefinitely. What's the trick ?

  • Java InputReader. Detect if file being read is binary?

    - by Trizicus
    I had posted a question in regards to this code. I found that JTextArea does not support the binary type data that is loaded. So my new question is how can I go about detecting the 'bad' file and canceling the file I/O and telling the user that they need to select a new file? class Open extends SwingWorker<Void, String> { File file; JTextArea jta; Open(File file, JTextArea jta) { this.file = file; this.jta = jta; } @Override protected Void doInBackground() throws Exception { BufferedReader br = null; try { br = new BufferedReader(new FileReader(file)); String line = br.readLine(); while(line != null) { publish(line); line = br.readLine(); } } finally { try { br.close(); } catch (IOException e) { } } return null; } @Override protected void process(List<String> chunks) { for(String s : chunks) jta.append(s + "\n"); } }

  • Proper use of HttpRequestInterceptor and CredentialsProvider in doing preemptive authentication with

    - by Preston
    I'm writing an application in Android that consumes some REST services I've created. These web services aren't issuing a standard Apache Basic challenge / response. Instead in the server-side code I'm wanting to interrogate the username and password from the HTTP(S) request and compare it against a database user to make sure they can run that service. I'm using HttpClient to do this and I have the credentials stored on the client after the initial login (at least that's how I see this working). So here is where I'm stuck. Preemptive authenticate under HttpClient requires you to setup an interceptor as a static member. This is the example Apache Components uses. HttpRequestInterceptor preemptiveAuth = new HttpRequestInterceptor() { @Override public void process( final HttpRequest request, final HttpContext context) throws HttpException, IOException { AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE); CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute( ClientContext.CREDS_PROVIDER); HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST); if (authState.getAuthScheme() == null) { AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort()); Credentials creds = credsProvider.getCredentials(authScope); if (creds != null) { authState.setAuthScheme(new BasicScheme()); authState.setCredentials(creds); } } } }; So the question would be this. What would the proper use of this be? Would I spin this up as part of the application when the application starts? Pulling the username and password out of memory and then using them to create this CredentialsProvider which is then utilized by the HttpRequestInterceptor? Or is there a way to do this more dynamically?

  • Best way to do interprocess communication on Mac OS X

    - by jbrennan
    I'm looking at building a Cocoa application on the Mac with a back-end daemon process (really just a mostly-headless Cocoa app, probably), along with 0 or more "client" applications running locally (although if possible I'd like to support remote clients as well; the remote clients would only ever be other Macs or iPhone OS devices). The data being communicated will be fairly trivial, mostly just text and commands (which I guess can be represented as text anyway), and maybe the occasional small file (an image possibly). I've looked at a few methods for doing this but I'm not sure which is "best" for the task at hand. Things I've considered: Reading and writing to a file (…yes), very basic but not very scalable. Pure sockets (I have no experience with sockets but I seem to think I can use them to send data locally and over a network. Though it seems cumbersome if doing everything in Cocoa Distributed Objects: seems rather inelegant for a task like this NSConnection: I can't really figure out what this class even does, but I've read of it in some IPC search results I'm sure there are things I'm missing, but I was surprised to find a lack of resources on this topic.

  • Is there an XML XQuery interface to existing XML files?

    - by xsaero00
    My company is in education industry and we use XML to store course content. We also store some course related information (mostly metainfo) in relational database. Right now we are in the process of switching from our proprietary XML Schema to DocBook 5. Along with the switch we want to move course related information from database to XML files. The reason for this is to have all course data in one place and to put it under Subversion. However, we would like to keep flexibility of the relational database and be able to easily extract specific information about a course from an XML document. XQuery seems to be up to the task so I was researching databases that supports it but so far could not find what I needed. What I basically want, is to have my XML files in a certain directory structure and then on top of this I would like to have a system that would index my files and let me select anything out of any file using XQuery. This way I can have "my cake and eat it too": I will have XQuery interface and still keep my files in plain text and versioned. Is there anything out there at least remotely resembling to what I want? If you think that what I an asking for is nonsense please make an alternative suggestion. On the related note: What XML Databases (preferably native and open source) do you have experience with and what would you recommend?

  • Why is OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true) causing an OCR running error?

    - by Ian Wells
    Hi folks, I am using MODI to read tiff images and do what I need to do with the text. Some images work fine and then other tiff images always cause the method, OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true) to fail. I have researched this and tried different variations such as 'false','false' in the parameter list. I have also tried SYSDEFAULT instead of English but I still get the error. Can anyone please tell me why it would fail on some tiff images and not on others? I have done some research and found this answer: One possible cause is MODI trying to process a file without any recognisable text. A blank document, or one which has only drawings/scribbles and is effectively blank, will cause this exception. Obviously this is not good enough as there is no way I can have an app that decides to OCR some images and not others. I handle the exception, but the OCR object is not then initalised so I can't do what I need to do from there. This is a bloody nightmare! Why can't the method just do it's bloody job and if the image has some unreadable pages then just ignore them? I am using Windows 7 Ultimate and Office 2007 Ultimate. Visual Studio version is 2008 Thanks, IW

  • HttpWebRequest.BeginGetResponse() does not return the second time

    - by evilfred
    Hi, I make one HttpWebRequest and call GetResponse() on it to get a synchronous response. Then after processing that response, I make a new HttpWebRequest and call BeginGetResponse() on it. Since BeginGetResponse() is an asynchronous call I expect it to return right away, but it doesn't! Why not? Here is some stripped down sample code: HttpWebRequest request = RequestFactory.MakeSessionCreationRequest(); try { // Get the response from the server. using (WebResponse response = request.GetResponse()) { using (Stream responseStream = response.GetResponseStream()) { ; // Get the response. } } ; // Process the response. } catch (WebException e) { Logger("Caught WebException when attempting to connect: " + e); return; } // Make the second, asynchronous request. HttpWebRequest msgRequest = RequestFactory.MakeMessageRequest(); IAsyncResult result = msgRequest.BeginGetResponse( new AsyncCallback(HandleResponse), msgRequest); // PROBLEM: This line is never reached!!! Logger("Message send started");

  • register device at run time

    - by user177893
    In the App ID section of the Program Portal, locate the App ID you wish to use with the Apple Push Notification service. Only App IDs with a specific bundle ID can be used with the APNs. You cannot use a “wild-card” application ID. You must see “Available” under the Apple Push Notification service column to register this App ID and configure a certificate for this App ID. Click the ‘Configure’ link next to your desired App ID. In the Configure App ID page, check the Enable Push Notification Services box and click the Configure button. Clicking this button launches the APNs Assistant, which guides you through the next series of steps that create your App ID specific Client SSL certificate. Download the Client SSL certificate file to your download location. Navigate to that location and double-click the certificate file (which has an extension of cer) to install it in your keychain. When you are finished, click Done in the APNS Assistant. Double-clicking the file launches Keychain Access. Make sure you install the certificate in your login keychain on the computer you are using for provider development. The APNs SSL certificate should be installed on your notification server. When you finish these steps you are returned to the Configure App ID page of the iPhone Dev Center portal. The certificate should be badged with a green circle and the label “Enabled”. To complete the APNs set-up process, you will need to create a new provisioning profile containing your APNs-enabled App ID. IS it posssible to do theses steps through code.

  • Splitting build cross the network?

    - by Dandikas
    Is there a known solution for splitting build process cross the network machines? Use case: We are an average software development company. We own around 50 development workstations (Quad Core 2.66Ghz, 4 GB ram, 200 GB raid). No need to tell that at any single moment not every machine is loaded to the max. There are 5 to 15 projects running simultaneously at any single moment. Obviously all of them are continuously build on server, than deployed to proper environment. Single project build is taking from 3 to 15 minutes. The problem: Whenever we build 5 projects in a row the last project is going to be ready after around 25 - 50 minutes. Building in parallel does not solve the problem (build is only a part of the game, than you need to deploy, run tests etc.) YES the correct solution is to add another build server, but "That involves buying new Expensive hardware, and we already spent a lot!". Yea, right(damn them)! Anyway. What about splitting build among developers workstation? Lets say whenever we need to build project "A" we check 5 workstations and start build on all that are not overloaded. The build can be canceled by a developer if he really needs all the power of his machine as long as there is at least 1 machine that is still building. After build is finished deployment can be performed to a proper environment (hosted on some server, not on workstation :) ). The bigger the company the more this makes sense to me. Anyone tried something like this? Are there any good practices? Any helpful software? (90% of the projects are .net C#)

  • multithreading issue

    - by vbNewbie
    I have written a multithreaded crawler and the process is simply creating threads and having them access a list of urls to crawl. They then access the urls and parse the html content. All this seems to work fine. Now when I need to write to tables in a database is when I experience issues. I have 2 declared arraylists that will contain the content each thread parse. The first arraylist is simply the rss feed links and the other arraylist contains the different posts. I then use a for each loop to iterate one while sequentially incrementing the other and writing to the database. My problem is that each time a new thread accesses one of the lists the content is changed and this affects the iteration. I tried using nested loops but it did not work before and this works fine using a single thread.I hope this makes sense. Here is my code: SyncLock dlock For Each l As String In links finallinks.Add(l) Next End SyncLock SyncLock dlock For Each p As String In posts finalposts.Add(p) Next End SyncLock ... Dim i As Integer = 0 SyncLock dlock For Each rsslink As String In finallinks postlink = finalposts.Item(i) i = i + 1 finallinks and finalposts are the two arraylists. I did not include the rest of the code which shows the threads working but this is the essential part where my error occurs which is basically here postlink = finalposts.Item(i) i = i + 1 ERROR: index was out of range. Must be non-negative and less than the size of the collection Is there an alternative?

  • dotNet Templated, Repeating, Databound ServerControl: Modifying underlying ServerControl data per te

    - by Campbeln
    I have a server control that wraps an underlying class which manages a number of indexes to track where it is in a dataset (ie: RenderedRecordCount, ErroredRecordCount, NewRecordCount, etc.). I've got the server control rendering great, but OnDataBinding I'm having an issue as to seems to happen after CreateChildControls and before Render (both of which properly manage the iteration of the underlying indexes). While I'm somewhat familiar with the ASP.NET page lifecycle, this one seems to be beyond me at the moment. So... How do I hook into the iterative process OnDataBinding uses so I can manage the underlying indexes? Will I have to iterate over the ITemplates myself, managing the indexes as I go or is there an easier solution? [edit: Agh... writing the problem out is very cathartic... I'm thinking this is exactly what I will need to do...] Also... I implemented the iteration of the underlying indexes during CreateChildControls originally in the belief that was the proper place to hook in for events like OnDataBinding (thinking it was done as the controls were being .Add'd). Now it seems that this may actually be unnecessary. So I guess the secondary question is: What happens during CreateChildControls? Are the unadulterated (read: with various <%-tags in place) controls added to the .Controls collection without any other processing?

  • Symfony - Several form on the same page -> ID issue

    - by Julien
    Hi folks. I have an issue while displaying several forms of the same model on the same page. The problem is that with the NameFormat, the fields have the same ID : $this->widgetSchema->setNameFormat('display[%s]'); Will display <form class="update_display_form" id="update_display_0" action="/iperf/web/frontend_dev.php/update_display" method="post"> <input type="checkbox" name="display[displayed]" checked="checked" id="display_displayed" /> <label for="display_displayed">test</label> </form> <form class="update_display_form" id="update_display_1" action="/iperf/web/frontend_dev.php/update_display" method="post"> <input type="checkbox" name="display[displayed]" checked="checked" id="display_displayed" /> <label for="display_displayed">truc</label> </form> And if you click on the second label, it will activate the first checkbox So I thought I could use the object id to make them unique : $this->widgetSchema->setNameFormat('display'.$this->getObject()->getId().'[%s]'); But then I can not process the request, since I don't know the name of the parameters. The best option I found was to set an ID : $this->widgetSchema['displayed']->setAttributes(array("id" => "display".$this->getObject()->getId() )); but then I totally loose the connections between the label and the checkbox. The problem would be solved if I could change the "for" attribute of my label. Does somebody know how to do that ? Or any other option ?

    - by Elliot
    I am getting weird errors when I try to convert a black and white PIL image to a numpy array. An example of the code I am working with is below. if image.mode != '1': image = image.convert('1') #convert to B&W data = np.array(image) #convert data to a numpy array n_lines = data.shape[0] #number of raster passes line_range = range(data.shape[1]) for l in range(n_lines): # process one horizontal line of the image line = data[l] for n in line_range: if line[n] == 1: write_line_to(xl, z+scale*n, speed) #conversion to other program code elif line[n] == 0: run_to(xl, z+scale*n) #conversion to other program code I have tried this using both array and asarray for the conversion, and gotten different errors. If I use array, then the data I get out is nothing like what I put in. It looks like several very shrunken partial images side by side, with the remainder of the image space filled in in black. If I use asarray, then the entirety of python crashes during the raster step (on a random line). If I work with a greyscale image ('L'), then neither of these errors occurs for either array or asarray. Does anyone know what I am doing wrong? Is there something odd about the way PIL encodes B&W images, or something special I need to pass numpy to make it convert properly?

  • SQL2008 merge replication fails to update depdendent items when table is added

    - by Dan Puzey
    Setup: an existing SQL2008 merge replication scenario. A large server database, including views and stored procs, being replicated to client machines. What I'm doing: * adding a new table to the database * mark the new table for replication (using SP_AddMergeArticle) * alter a view (which is already part of the replicated content) is updated to include fields from this new table (which is joined to the tables in the existing view). A stored procedure is similarly updated. The problem: the table gets replicated to client machines, but the view is not updated. The stored procedure is also not updated. Non-useful workaround: if I run the snapshot agent after calling SP_AddMergeArticle and before updating the view/SP, both the view and the stored procedure changes correctly replicate to the client. The bigger problem: I'm running a list of database scripts in a transaction, as part of a larger process. The snapshot agent can't be run during a transaction, and if I interrupt the transaction (e.g. by running the scripts in multiple transactions), I lose the ability to roll back the changes should something fail. Does anyone have any suggestions? It seems like I must be missing something obvious, because I don't see why the changes to the view/sproc wouldn't be replicating anyway, regardless of what's going on with the new table.

  • Questions related to mantis:

    - by Komal Matkar
    We are interested in installing Mantis but we have some doubts Please clarify as early as possible if you can so that we can go for further process. 1) We have one team at USA (Client’s place) and one is at India. In which server we should install the Mantis. If we are installing at USA will it run slow in India? 2) What about technical Support. You may take technical support with payment. But how much support will be given free (As we have to discuss this with client). 3) As we have seen details in your website, you have given it supports oracle and sql database. But we wanted to know till which lowest version of oracle and sql it supports. Please send us minimum requirement. 4) What is the capacity of the database to store defects? Backup facility is available? If yes please tell us how should we take. Because we have big team and 5-6 applications so it should not give further problems. 5) Database support: Do you provide database support or database while installation? While installing all the prerequisite application will get installed or we need any application separately. 6)How many users can access at a time? Will it work slowly if more users are working at a time? Thanks Komal
