  • How to assign a value to an pointer-pointer passed in call by reference?

    - by mystify
    I want to achieve something similar to what these guys do here: - (NSUInteger)countForFetchRequest:(NSFetchRequest *)request error:(NSError **)error like you can see, you pass an NSError pointer and that nice method will assign a real NSError object to your pointer in case there is an error. So the cool thing about this is, that the method returns an NSUInteger but can ALSO return an NSError, without having to mess around with ugly and fat arrays or dictionaries. So how could I assign an object to the passed-in error pointer?

  • Go - Raise an exception

    - by nevalu
    I would want to raise an exception as it's made in Python or Java --to finish the program with an error message--. An error message could be returned to a parent function: func readFile(filename string) (content string, err os.Error) { content, err := ioutil.ReadFile(filename) if err != nil { return "", os.ErrorString("read " + filename + ": " + err) } return string(content), nil } but I want that it can be finished when the error is found. Would be correct the next one? func readFile(filename string) (content string) { content, err := ioutil.ReadFile(filename) defer func() { if err != nil { panic(err) } }() return string(content) }

  • MySQLi Insert prepared statement via PHP

    - by Jimmy
    Howdie do, This is my first time dealing with MySQLi inserts. I had always used mysql and directly ran the queries. Apparently, not as secure as MySQLi. Anywho, I'm attempting to pass two variables into the database. For some reason my prepared statement keeps erroring out. I'm not sure if it's a syntax error, but the insert just won't work. I've updated the code to make the variables easier to read Also, the error is specifically, Error preparing statement. I've updated the code, but it's not a pHP error. It's a MySQL error as the script runs but fails at the execution of: if($stmt = $mysqli - prepare("INSERT INTO subnets (id, subnet, mask, sectionId, description, vrfId, masterSubnetId, allowRequests, vlanId, showName, permissions, pingSubnet, isFolder, editDate) VALUES ('', ?, ?, '1', '', '0', '0', '0', '0', '0', '{"3":"1","2":"2"}', '0', '0', 'NULL')")) { I'm going to enable MySQL error checking. I honestly didn't know about that. <?php error_reporting(E_ALL); function InsertIPs($decimnal,$cidr) { error_reporting(E_ALL); $mysqli = new mysqli("localhost","jeremysd_ips","","jeremysd_ips"); if(mysqli_connect_errno()) { echo "Connection Failed: " . mysqli_connect_errno(); exit(); } if($stmt = $mysqli -> prepare("INSERT INTO subnets (id, subnet, mask,sectionId,description,vrfld,masterSubnetId,allowRequests,vlanId,showName,permissions,pingSubnet,isFolder,editDate) VALUES ('',?,?,'1','','0','0','0','0','0', '{'3':'1','2':'2'}', '0', '0', NULL)")) { $stmt-> bind_param('ii',$decimnal,$cidr); if($stmt-> execute()) { echo "Row added successfully\n"; } else { $stmt->error; } $stmt -> close; } } else { echo 'Error preparing statement'; } $mysqli -> close(); } $SUBNETS = array ("2915483648 | 18"); foreach($SUBNETS as $Ip) { list($TempIP,$TempMask) = explode(' | ',$Ip); echo InsertIPs($Tempip,$Tempmask); } ?> This function isn't supposed to return anything. It's just supposed to perform the Insert. Any help would be GREATLY appreciated. I'm just not sure what I'm missing here

  • Sphinx search: failed to unpack mysqlcompress column

    - by Un_tangable
    I have compiled sphinx 0.9.9 for debian x64. When I try to index using unpack_mysqlcompress, I get this error: "WARNING: failed to unpack column 'page_text', error=-5" The 'page_text' field is around 5Kb, and unpack_mysqlcompress_maxsize is set to 64M, yet the zlib manual says error -5 indicates Z_BUF_ERROR. Also if mysql does the decompression using UNCOMPRESS(), it works fine. Any ideas why sphinx is generating this error?

  • Add button to a layout programmatically

    - by mmmbaileys
    I'm having trouble adding a button to a layout that I've created in XML. Here's what I want to achieve: //some class else { startActivity(new Intent(StatisticsScreen.this, ScreenTemperature.class)); } //// //ScreenTemperatureClass @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //this is where I call another class that //displays a nice graph setContentView(new GraphTemperature(getApplicationContext())); } I want to add a Button to this new screen so that it'll appear below the graph. I've tried creating a LinearLayout view, then create a Button and add it to this view but I just get NullPointerExceptions.. Any help would be appreciated. Thanks EDIT#1 Here's what I've tried using that created a NullPointerException and 'force close': Button buybutton; LinearLayout layout; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(new GraphTemperature(getApplicationContext())); layout = (LinearLayout) findViewById(R.id.statsviewlayout); Button buyButton = new Button(this); buyButton.setText(R.string.button_back); buyButton.setLayoutParams(new LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); layout.addView(buyButton); } And here's the logcat error: ERROR/AndroidRuntime(293): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.weatherapp/com.weatherapp.ScreenTemperature}: java.lang.NullPointerException ERROR/AndroidRuntime(293): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663) ERROR/AndroidRuntime(293): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) ERROR/AndroidRuntime(293): at android.app.ActivityThread.access$2300(ActivityThread.java:125) ERROR/AndroidRuntime(293): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) theres abviously more lines to do with this error in logcat, not sure if you want it? EDIT#2 So i tried bhups method: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); GraphTemperature GT = new GraphTemperature(getApplicationContext()); layout = (LinearLayout) findViewById(R.id.statsviewlayout); Button buyButton = new Button(this); buyButton.setText(R.string.button_back); buyButton.setLayoutParams(new LayoutParams( ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT)); layout.addView(GT); // line 27 layout.addView(buyButton); setContentView(layout); } This method produced the same logcat error as above, NullPointerException, indicating it was something to do with line no. 27 which is the layout.addView line of code. Any ideas? Thanks again

  • Would a pointer to a pointer to nil match against NULL?

    - by dontWatchMyProfile
    Example: A validation method contains this check to see if an NSError object shall be created or not: - (BOOL)validateCompanyName:(NSString *)newName error:(NSError **)outError { if (outError != NULL) { // do it... Now I pass an NSError object, like this: NSError *error = nil; BOOL ok = [self validateCompanyName:@"Apple" error:&error]; I'm not sure if this matches the check for not NULL. I think it's not NULL, since I believe NULL is not nil. Maybe someone can clear this up?

  • IIS 7.5 FTPS external access - 534 Policy requires SSL

    - by markmnl
    I have setup a FTP site that requires SSL but when I try connect to it externally I get the error: 220 Microsoft FTP Service 534 Policy requires SSL. I know - I set it so! Why doesnt it fetch the SSL cert from the site and allow me to logon?! (Incidentally beware of all the tutorials that Allow but do not Require SSL - while that will solve the problem it will be because SSL is not being used!). I suspect it may be I need a client that supports FTPS (FTP over SSL) and Windows explorer just uses IE which does not. But trying FileZilla and WinSCP I get a little further but then it hangs on TLS/SSL negotiation expecting a response from the server.... UPDATE: I have tried (from: http://learn.iis.net/page.aspx/309/configuring-ftp-firewall-settings/): Configure the Passive Port Range for the FTP Service. Configure the external IPv4 Address for a Specific FTP Site. Configure the firewall to allow the FTP service to listen on all ports that it opens. Disabling stateful FTP filtering so that Windows Firewall will not block FTP traffic. And still I get (in FileZilla trying both Active and Passive): Status: Connecting to 203.x.x.x:21... Status: Connection established, waiting for welcome message... Response: 220 Microsoft FTP Service Command: AUTH TLS Response: 234 AUTH command ok. Expecting TLS Negotiation. Status: Initializing TLS... Error: Connection timed out Error: Could not connect to server The Windows firewall logs unhelpfully have nothing to say.. UPDATE2: Turning the firewall off does not resolve the problem. I cannot believe how difficult it is to get something so simple to work and even once following the documentation it does not work. UPDATE3: Running FileZilla locally connecting through the loopback works in Active mode, in Passive mode I get up to: Command: LIST Response: 150 Opening BINARY mode data connection. Error: GnuTLS error -53: Error in the push function. Turning the firewall off at both ends I can still not connect the client and get the same error as above.

  • surgemail vs Exchange

    - by Gaz
    At work we are running Surgemail. The desktop mail client is Outlook which downloads mail over POP3, and so email is stored on users desktops in PST files. Looking at the features of Surgemail compared to Exchange 2007 can anyone provide a convincing argument to change? The argument must be user related or disaster recovery related they can not be about administration of the system.

  • Forbidden access on Apache in Mac Lion

  • Can't connect to DeploymentShare$ from PC attempting to MDT, but can other PCs on the network

    - by Moman10
    I am in the process of setting up MDT and have run across a problem. MDT is installed on a Windows 2012 server, MDT version 6.2.5019.0. Using WDS as well. Active Directory domain, the server is up to date and on the network. I boot up the PC, it gets an address from DHCP, pulls down the LiteTouchPE_x64.wim image and goes into the MS Solution Accelerators screen, the Processing Bootstrap Settings box comes up and processes for a couple of seconds, then goes away, it sits there for another minute or so and then gives the error: A connection to the deployment share (\\Acme-MDT\DeploymentShare$) could not be made. Can not reach the DeployRoot. Possible Cause: Network Routing error or Network Configuration Error." I can then retry or cancel. I have seen this error online but so far nothing that helps fix it, but seems to be an issue with the FQDN. I verified that I am getting an IP address and that I can successfully ping the MDT server if I use the FQDN, but can not just by it's A record of Acme-MDT. I tried manually mapping the network share using net use and it works if I use the FQDN, but it fails with an error code 53, "Network path not found" if I just use the A record of Acme-MDT. Here is the net use command I'm using: net use * \\Acme-MDT\DeploymentShare$ /u:Domain\Administrator It gives the error System Error 53, Network path not found (and doesn't prompt for a password), but if I use the FQDN of \\Acme-MDT.domain.com\DeploymentShare$ it works fine to map the drive. I guess the problem is, when it tries to load the image, it is trying to start from \\Acme-MDT\DeploymentShare$ and I need it to start from \\Acme-MDT.domain.com\DeploymentShare$, but not sure how to get it to do that. I've put the fully qualified path in CustomSettings.ini and bootstrap, updated the deployment share, regenerated the boot image and replaced the boot wim in WDS. Or, if someone has an idea as to why it's acting this way and knows a way around it. The end result is what matters! :) I did verify in DNS that Acme-MDT is there, with the proper IP, and I can successfully use the net use command to map this drive from a couple other computers that are already on the network. I am assuming it has something to do with that computer not already being part of the domain, but I'm honestly at a loss as to how to fix it. Any ideas are appreciated, thanks in advance for your help!

  • TrueCrypt drive letter not available

    - by Tono Nam
    With c# or a batch file I mount a trueCrypt volume located at A:\volumeTrueCrypt.tc With c# I do: static void Main(string[] args) { var p = Process.Start( fileName:@"C:\Program Files\TrueCrypt\TrueCrypt.exe", arguments:@"/v a:\volumetruecrypt.tc /lw /a /p truecrypt" ); p.WaitForExit(); } the alternative is to run the command on the command line as: C:\Windows\system32>"C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /lw /a /p truecrypt Either way I get the error: Why do I get that error? I was able to run that command the first time. The moment I dismounted the volume and tryied to mount it again I got that error. I know that drive letter W is available because it shows as an available letter on true crypt if I where to open it manually: If I where then click on the button mount and then type the password truecrypt (truecrypt is the password) then it will successfully mount on drive w. Why I am not able to mount it from the command line!? If I change the drive letter on the command line it works. I want to use the drive W though. In other words executing "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /lz /a /p truecrypt will successfully mount that volume on drive z but I do not want to mount it on drive z I want to mount it on drive w. The first time I ran the batch it ran fine. Also if I restart my computer I believe it should work. More info on how to use trueCrypt through the command line can be found at: http://www.truecrypt.org/docs/?s=command-line-usage Edit I was also investivating when does this error occures. In order to generate this error you need to follow this steps. 1) execute the command: (note the /q argument at the end for quiet) "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /ln /a /p truecrypt /q "C...TrueCrypt.exe" = location where trueCrypt is located /v "path" = location where volume is located /n = drive letter n /p truecrypt = password is "trueCrypt" /q = execute in quiet mode. do not show window note I am mounting to drive letter n 2) now volume should be mounted. 3) Open trueCrypt and manually dismount that volume (without using command line) 4) Attempt to run the same command line (without the /q so you see the error) "C:\Program Files\TrueCrypt\TrueCrypt.exe" /v "a:\volumetruecrypt.tc" /ln /a /p truecrypt 5) an error should show up So the problem ocures when I manually dismount the volume. If I dismount it from the command line I get no errors. But I think this is a bug from trueCrypt

  • long access times and errors in iis application

    - by user55862
    I am having an issue with an IIS application (details of environment at the end of the message). The web site works great most of the time and I cannot reproduce any error in our test system. On the live system however with on averare of 5-15 requests per second I have a problem with that some requests (about 0.05%) will take over 300 seconds to complete. The other requests complete withing 5-10 seconds. It seem like if all the errornous requests end up with a Timer_EntityBody error in the error log. I have never seen this as an end user but I guess that they will receive some kind of error message. I am trying to find out what can be causing this errornous behaviour. Any ideas are welcome. I have read something about that there can be an MTU issue if ICMP and MTU protocols are blocked in the firewall. Does that sound reasonable? I have also read about updating to IIS 7 should do the trick. Does it sound reasonable? I think that the problem has another cause but I have no idea of what. I have tried running hte perormance monitor, monitoring for database locks and active transaction counts. I can see some of these in the perfmon log for the MSSQL server (another machine) for example: Active transactions is sometimes peaking and sometimes for long periods Lock waits per seconds is sometimes peaking Transactions per second is sometimes peaking Page IO Latch wait is sometimes peaking Lock wait time (ms) is sometimes peaking But I cannot see that any of these correlate to the errors in the IIS error log. On the IIS server machine I can also see with perfmon that some values peak a few times during a day: Request execution time Avg disk queue length I can neither see that any of these correlate to the errors in the IIS error log. In the below code I have anonymized by replacing some parts with HIDDEN The following can be seen in the access log 2010-10-01 08:35:05 W3SVC1301873091 **HIDDEN** POST /**HIDDEN**/Modules/BalanceModule.aspx - 80 - **HIDDEN** Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+5.1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.4506.2152;+.NET+CLR+3.5.30729;+.NET4.0C;+.NET4.0E) ASP.NET_SessionId=**HIDDEN** 400 0 64 0 2241 127799 At the same time the following can be seen in the error log: 2010-10-01 08:35:05 **HIDDEN** 1999 **HIDDEN** 80 HTTP/1.0 POST /**HIDDEN**/Modules/BalanceModule.aspx - 1301873091 Timer_EntityBody Test+Pool I can tell the following about the environment: Server: Windows Server 2003 x64 SP2 running on VMWare HTTP Server: IIS v6.0 with ASP.NET 2.0.50727 Antivirus: Trend Micro OfficeScan (Is it a good idea to have this on a server?)

  • Trailing dots in url result in empty 404 page on IIS

    - by Peter Hahndorf
    I have an ASP.NET site on IIS8, but IIS7.5 behaves exactly the same. When I enter a URL like: mysite.com/foo/bar.. I get the following error with a '500 Internal Server Error' status code: even though I have custom error pages set up for 500 and 404 and I don't see anything wrong with my custom error page. In my web.config system.web node I have the following: <customErrors mode="On"> <error statusCode="404" redirect="/404.aspx" /> </customErrors> If I remove that section, I get a 404.0 response back but the page itself is blank. In web.config system.webServer I have: <httpErrors errorMode="DetailedLocalOnly"> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" prefixLanguageFilePath="" path="404.html" responseMode="File" /> </httpErrors> But whether that is there or not, I get the same blank 404.0 page rather than my expected custom error page, or at least an internal IIS message. So first of all why is the asp.net handler picking up a request for '..' (also works with one or more trailing dots) If I remove the following handler from applicacationHost.config: <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" responseBufferLimit="0" /> I get my expected custom 404 page, but of course removing that handler breaks routing in asp.net among other things. Looking at the failure trace I see: Windows Authentication is disabled for the site, so why is that module even in the request pipeline? For now my fix is to use the URL Rewrite module with the following rule: <rewrite> <rules> <rule name="Trailing Dots" stopProcessing="true"> <match url="\.+$" /> <action type="Rewrite" url="/404.html" appendQueryString="false" /> </rule> </rules> </rewrite> This works okay, but I wonder why IIS/ASP.NET behaves this way?

  • How do I get the latest FastCGI and PHP versions to peacefully coexist on IIS 6?

    - by BHelman
    I have been going round and round trying to get any sort of PHP running on IIS 6. I somehow managed to successfully get version 5.1.4 running using the php5isapi.dll file. However, I want to upgrade a website to begin using a Content Management System. I have never dug into CMS before so I'm open to programs that are easy to use. I am currently looking into TomatoCMS and ImpressCMS - but that's beside the point. I have never done an installation with PHP before and I think I'm getting familiar with how it works. However the current situation is this. Microsoft's Web Platform Installer 2.0 installed FastCGI for me. I need to upgrade to PHP 5.3.1 for a CMS system. So I downloaded the Windows installer and let it go at it. After consulting several other blog articles, I believe I know how it is supposed to work but I am currently not having luck. THE SETUP *.php is a registered extension in IIS 6 for all websites (on Win 2k3). The application that it calls is C:\Windows\system32\inetsvr\fcgiext.dll, like it should. The fcgiext.ini config has the proper lines: [Types] php=PHP [PHP] ext=C:\program files\PHP\php-cgi.exe And the php.ini file also has the correct configs. All extensions are disabled and I changed the correct things for FastCGI. And everything is registered correctly with the PATH variable. Everything is exactly how it should be. BUT when I launch the "info.php" page () on another computer, I get the following error: FastCGI Error The FastCGI Handler was unable to process the request. Error Details: * Section [PHP] not found in config file. * Error Number: 1413 (0x80070585). * Error Description: Invalid index. HTTP Error 500 - Server Error. Internet Information Services (IIS) A quick Google search reveals that I have it all setup correctly as far as the INI's go and the mapping of the php extension. I am completely at a loss. Does anyone have any suggestions? Although the server is hosting three small websites, I don't really care what I have to do to it to get it to work.

  • Tomcat can't talk to MySql after outage

    - by gav
    I missed a payment for my server and hey suspended my account for a day or so. When they brought the server back up all my data was in tact but for some reason Tomcat can't make a JDBC connection to my MySql server. They both run on the same machine and hence I have a bind address of 127.0.0.1. It's strange because I have reset the machine of my own accord before without issue but clearly something has been reset in the downtime. I followed this guide (Just the bits which don't concern S3, I am not on Amazon infrastructure) originally and everything worked as expected. I'm very new to being a SysAdmin and I'm not sure what to try, how would you go about diagnosing this issue? The stack trace I get is as follows; INFO: Deploying web application archive myapp-1.1.war 2010-05-26 22:07:22,221 [main] ERROR context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageSource': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Cannot resolve reference to bean 'hibernateProperties' while setting bean property 'hibernateProperties'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateProperties': Cannot resolve reference to bean 'dialectDetector' while setting bean property 'properties' with key [hibernate.dialect]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dialectDetector': Invocation of init method failed; nested exception is org.springframework.jdbc.support.MetaDataAccessException: Could not get Connection for extracting meta data; nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (Communications link failure The last packet sent successfully to the server was 0 milliseconds ago.

I get this error for a number of 'beans'. If I type mysql at my command prompt then I can easily login with the same credentials as my grails app which uses GORM and Hibernate to persist objects to the DB. I might not have given enough info to start with but I'm really interested to learn and will certainly provide it if asked, I just really don't know where to start on this one. Thanks, Gav
