  • ODBC vs MySQLClient

    - by Matt
    I'm currently using ODBC to connect to my MySQL database, using C#. I've been told that using the MySql Connector would be better, and faster, and not dependent on Windows. Can someone shed some light on this please? I've been unable to find anything on the net so far

  • iPhone sdk can't get Mobclix to work

    - by Matt S.
    I followed the guide here, and when I build my application the ad (or anything for that matter) doesn't show up. Nothing, nada. I followed the guide very carefully. I know that it is trying to retrieve an ad (thanks to little snitch), but it doesn't display. Has anybody experienced this and do you know of a fix?

  • PHP templating challenge (optimizing front-end templates)

    - by Matt
    Hey all, I'm trying to do some templating optimizations and I'm wondering if it is possible to do something like this: function table_with_lowercase($data) { $out = '<table>'; for ($i=0; $i < 3; $i++) { $out .= '<tr><td>'; $out .= strtolower($data); $out .= '</td></tr>'; } $out .= "</table>"; return $out; } NOTE: You do not know what $data is when you run this function. Results in: <table> <tr><td><?php echo strtolower($data) ?></td></tr> <tr><td><?php echo strtolower($data) ?></td></tr> <tr><td><?php echo strtolower($data) ?></td></tr> </table> General Case: Anything that can be evaluated (compiled) will be. Any time there is an unknown variable, the variable and the functions enclosing it, will be output in a string format. Here's one more example: function capitalize($str) { return ucwords(strtolower($str)); } If $str is "HI ALL" then the output is: Hi All If $str is unknown then the output is: <?php echo ucwords(strtolower($str)); ?> In this case it would be easier to just call the function (ie. <?php echo capitalize($str) ?> ), but the example before would allow you to precompile your PHP to make it more efficient

  • .Net System.Mail.Message adding multiple "To" addresses

    - by Matt Dawdy
    I just hit something I think is inconsistent, and wanted to see if I'm doing something wrong, if I'm an idiot, or... MailMessage msg = new MailMessage(); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); msg.To.Add("[email protected]"); Really only sends this email to 1 person, the last one. To add multiples I have to do this: msg.To.Add("[email protected],[email protected],[email protected],[email protected]"); I don't get it. I thought I was adding multiple people to the "To" address collection, but what I was doing was replacing it. I think I just realized my error -- to add one item to the collection, use .To.Add(new MailAddress("[email protected]")) If you use just a string, it replaces everything it had in its list. Ugh. I'd consider this a rather large gotcha! Since I answered my own question, but I think this is of value to have in the stackoverflow archive, I'll still ask it. Maybe someone even has an idea of other traps that you can fall into.

    Hi, Here is my button <asp:Button ID="myButton" Text="Click Me" OnClick="doSomething(10)" runat="server" /> Here is the server function public void doSomething(int num) { int someOtherNum = 10 + num; } When I try to compile the code I get the error "Method Name Expected" for the line: <asp:Button ID="myButton" Text="Click Me" OnClick="doSomething(10)" runat="server" /> What am I doing wrong? Am I not allowed to pass values to the server from an OnClick event?

  • When to use a module, and when to use a class

    - by Matt Briggs
    I am currently working through the Gregory Brown Ruby Best Practices book. Early on, he is talking about refactoring some functionality from helper methods on a related class, to some methods on module, then had the module extend self. Hadn't seen that before, after a quick google, found out that extend self on a module lets methods defined on the module see each other, which makes sense. Now, my question is when would you do something like this module StyleParser extend self def process(text) ... end def style_tag?(text) ... end end and then refer to it in tests with @parser = Prawn::Document::Text::StyleParser as opposed to just using a class with some class methods on it? is it so that you can use it as a mixin? or are there other reasons I'm not seeing?

  • Trouble extending event log messages

    - by Matt H
    Hi. I'm trying to add some extended error codes to the event log but I get the following error. The description for Event ID ( 109 ) in Source ( PumpServer ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: The event log file is corrupt.. The message file looks like this and I added the one on the end:- <---snip---> MessageId= SymbolicName=EVMSG_BADREQUEST Language=English The service received an unsupported request. . MessageId= SymbolicName=EVMSG_DEBUG Language=English %1 . MessageId= SymbolicName=EVMSG_STOPPED Language=English The service was stopped. . MessageId= SymbolicName=EVMSG_INVALIDLICENCE Language=English The service does not have a valid licence. Initialization failed. . It compiles fine. The mc program is running over this file and producing a header file of the same name with my new message id showing. // // MessageId: EVMSG_INVALIDLICENCE // // MessageText: // // The service does not have a valid licence. Initialization failed. // #define EVMSG_INVALIDLICENCE 0x0000006DL Any ideas why it's not finding my message? All the others work.

  • How to obtain the root of a tree without parsing the entire file?

    - by Matt.
    I'm making an xml parser to parse xml reports from different tools, and each tool generates different reports with different tags. For example: Arachni generates an xml report with <arachni_report></arachni_report> as tree root tag. nmap generates an xml report with <nmaprun></nmaprun> as tree root tag. I'm trying not to parse the entire file unless it's a valid report from any of the tools I want. First thing I thought to use was ElementTree, parse the entire xml file (supposing it contains valid xml), and then check based on the tree root if the report belongs to Arachni or nmap. I'm currently using cElementTree, and as far as I know getroot() is not an option here, but my goal is to make this parser to operate with recognized files only, without parsing unnecessary files. By the way, I'm Still learning about xml parsing, thanks in advance.

  • Securely persist session between https://secure.yourname.com and http://www.yourname.com on rails ap

    - by Matt
    My rails site posts to a secure host (e.g. 'https://secure.yourname.com') when the user logs into the site. Session data is stored in the database, with the cookie containing only the session ID. The problem is that when the user returns to a non-https page, such as the home page (e.g. 'http://www.yourname.com') the user appears to have logged out. I believe the reason for this is that a separate cookie is stored for each host (www vs. secure). Is this correct? What is the best secure way to persist the session between both the http and https sections of the site? Does anyone know of any plugins that address this problem? The site runs on Heroku.

  • Cocoa app not launching on build & go but launching manually

    - by Matt S.
    I have quite the interesting problem. Yesterday my program worked perfectly, but now today I'm getting exc_bad_access when I hit build and go, but if I launch the app from the build folder it launches perfectly and there seems to be nothing wrong.

  • Get All Users in an Active Directory Group

    - by Matt Hanson
    I'm using the following code sample to get a list of all users in a specified AD group (in this case, all users in the "Domain Users" group). My listed code works great, with one exception: it won't return users who have their primary group set to "Domain Users". How can I get a list of all users in the group, including those who have it set as their primary group? Private Sub GetUsers() Dim groupSearcher As New DirectorySearcher Dim groupSearchRoot As New DirectoryEntry("LDAP://OU=Users,DC=domain,DC=com") With groupSearcher .SearchRoot = groupSearchRoot .Filter = "(&(ObjectClass=Group)(CN=Domain Users))" End With Dim members As Object members = groupSearcher.FindOne.GetDirectoryEntry.Invoke("Members", Nothing) For Each member As Object In CType(members, IEnumerable) Console.WriteLine(New DirectoryEntry(member).Name.Remove(0, 3)) Next End Sub

  • Start thread with two parameters

    - by Matt
    I've got a method that gets called on an event, which presents me with two variables varA, varB (both strings). This method gets called with new information quite frequently, thus I have created a separate method that takes in the two parameters. I want to run this method in a thread, however have struck the issue that Thread.Start will not accept parameters. I've tried a few supposed methods, but have so far had no luck.. I think my best bet is to create a separate class, and handle it there.. However I have a List which I am inserting data into, and hit a dead end when the separate class tried to access that list, since it was in a different class. Can someone help me out here please?

  • How does Bitmap.Save(Stream, ImageFormat) format the data?

    - by Matt Jacobsen
    I have a non transparent, colour bitmap with length 2480 and width 3507. Using Bitmap.GetPixel(int x, int y) I am able to get the colour information of each pixel in the bitmap. If I squirt the bitmap into a byte[]: MemoryStream ms = new MemoryStream(); bmp.Save(ms, ImageFormat.Bmp); ms.Position = 0; byte[] bytes = ms.ToArray(); then I'd expect to have the same information, i.e. I can go to bytes[1000] and read the colour information for that pixel. It turns out that my array of bytes is larger than I anticipated. I thought I'd get an array with 2480 x 3507 = 8697360 elements. Instead I get an array with 8698438 elements - some sort of header I presume. In what format the bytes in my array stored? Is there a header 1078 bytes long followed by Alpha, Red, Green, Blue values for every byte element, or something else?

  • send keystrokes from iphone to PC

    - by Matt Facer
    hi guys. I'm looking to create a simple app which will send keystrokes from an iphone to a PC. I understand that I will need to have a program on my PC "listening"... I've been looking in to AsyncSocket and NSStream, but there are no tutorials which really make it clear to understand. Does anyone know if this is right? I basically want to interact with a program on my PC which listens for keystrokes to control it. Does anyone know of a tutorial or place where I could start to learn this? (I've written iphone apps before, but I am new to networking)

  • Return a value if no rows are found SQL

    Here's my simple query. If I query a record that doesn't exist then I will get nothing returned. I'd prefer that false (0) is returned in that scenario. Looking for the simplist method to account for no records. SELECT CASE WHEN S.Id IS NOT NULL AND S.Status = 1 AND (S.WebUserId = @WebUserId OR S.AllowUploads = 1) THEN 1 ELSE 0 END AS [Value] FROM Sites S WHERE S.Id = @SiteId

  • Security of WCF endpoints

    - by Matt
    For the sake of argument, lets say that I've got a basicHttp WCF service. Besides implementing authentication (login/logout methods), what is stopping someone from just cracking open Visual Studio, adding a web reference to my website's service, and then playing playing around with my service? I'm not familiar with a method of stopping someone from doing this. The idea of someone downloading all of my Data/Operation contracts and then start playing around is keeping me up at night, and I like my sleep!

  • How do I call setattr() on the current module?

    - by Matt Joiner
    What do I pass as the first parameter "object" to the function setattr(object, name, value), to set variables on the current module? For example: setattr(object, "SOME_CONSTANT", 42); giving the same effect as: SOME_CONSTANT = 42 within the module containing these lines (with the correct object). I'm generate several values at the module level dynamically, and as I can't define __getattr__ at the module level, this is my fallback.

  • Unit Testing Model Classes that inherit from NSManagedObject

    - by Matt Baker
    So...I'm trying to get unit tests set up in my iPhone App but I'm having some issues. I'm trying to test my model classes but they inherit directly from NSManagedObject. I'm sure this is a problem but I don't know how to get around it. Everything is building and running as expected but I get this error when calling any method on the class I'm testing: Unknown.m:0:0 unrecognized selector sent to instance 0xc2b120 If I follow this structure (http://chanson.livejournal.com/115621.html) to create my object in my tests I end up with another error entirely but it still doesn't help me. Basically my question is this: how can I test a class that inherits from NSManagedObject?

  • Reading Windows ACLs from Java

    - by Matt Sheppard
    From within a Java program, I want to be able to list out the Windows users and groups who have permission to read a given file. Obviously Java has no built-in ability to read the Windows ACL information out, so I'm looking for other solutions. Are there any third party libraries available which can provide direct access to the ACL information for a Windows file? Failing that, maybe running cacls and capturing and then processing the output would be a reasonable temporary solution - Is the output format of cacls thoroughly documented anywhere, and is it likely to change between versions of Windows?
