  • Debug formatting code

    - by Arcadian
    I'm trying to debug my code here: private void CheckFormatting() { StringReader objReaderf = new StringReader(txtInput.Text); List<String> formatTextList = new List<String>(); do { formatTextList.Add(objReaderf.ReadLine()); } while (objReaderf.Peek() != -1); objReaderf.Close(); for (int i = 0; i < formatTextList.Count; i++) { if (!Regex.IsMatch(formatTextList[i], "G[0-9]{2}:[0-9]{2}:[0-9]{2}:[0-9]{2} JG[0-9]{2")) { MessageBox.Show("Line " + formatTextList[i] + " is not formatted correctly.", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error); break; } else { this.WriteToFile(); MessageBox.Show("Your entries have been saved.", "Saved", MessageBoxButtons.OK, MessageBoxIcon.Information); } } } what it is supposed to do is to check each line in the list. if one of them isn't formatted correctly, then break the loop and display a message box, if all the lines are formatted properly then it should call the WriteToFile method. However, when testing it using input that WAS correctly formatted it displayed the error message and broke the loop. Anyone figure out why? There's some rep points in it for you :) Thanks in advance

  • Dreaded iframe horizontal scroll bar can't be removed in IE?

    - by mrjrdnthms
    I have an iframe. The content is wider than the width I am setting so the iframe gets a horizontal scroll bar. I can't increase the width of the iframe so I want to just remove the scroll bar. I tried setting the scroll property to "no" but that kills both scroll bars and I want the vertical one. I tried setting overflow-x to "hidden" and that killed the horizontal scroll bar in ff but not in IE. sad for me.

  • Load iframe in html, only with jquery

    - by phpExe
    In this jquery code: $(document).ready(function(){ $list = $(".channeList li"); $list.click(function(){ var $this = $(this); var $mainDesc = $(".ply"); var iframe = $("a", $this).attr("rel"); $("iframe", $mainDesc).attr("src", iframe); } ); } ); There is a list o channels in left that iframe loads from a rel's. I want to load first iframe in <div class="ply"></div> In html, I dont want insert the first item. Can we do this without load first item in html and do this only with jquery? The php function channel() { if (is_numeric($_GET['kanalID'])) { $kanalID = $_GET['kanalID']; } if ($_GET['kanalID'] == "") { $kanalID = 1;} $channel = '<ul class="channeList">'; foreach ($tv as $id => $kanal) { $class = $kanalID == $id ? $class = "currentt": ''; $channel .= '<li> <a href="#" rel="http://mysite.com/index.php?id='.$id.'&w=500&h=320" >'.$kanal.'</a></li>'; } $channel .= '</ul>'; $channel .= '<div class="ply"><iframe frameborder=0 width="500" height="320"></iframe></div>'; return $channel; } Thanks in advance

  • Hash passwords before transmitting? (web)

    - by wag2639
    I was reading this Ars article on password security and it mentioned there are sites that "hash the password before transmitting"? Now, assuming this isn't using an SSL connection (HTTPS), a. is this actually secure and b. if it is how would you do this in a secure manor? Edit 1: (some thoughts based on first few answers) c. If you do hash the password before transmission, how do you use that if you only store a salted hash version of the password in your user credentials databas? d. Just to check, if you are using a HTTPS secured connection, is any of this necessary?

  • Filtering forms in MS Access

    - by terence6
    I have a simple form showing products from my database. Each product has a foreign key to manufacturer_id . I would like to filter my form by manufacturer_id instead of default product_id. How I can do that ? I know I must create a macro. Also I've already created a query, that takes manufacturer's name as argument and returns manufacturer_id. So basically it should work in this way, that when I press 'Filter' button on my form, it runs macro that opens my query asking for manufacturer's name. And when the name is returned the whole form is filtered (so somewhere there should be comparison between manufacturer_id in product and that returned from query, but I can't manage to do that). I'm using access 2007. Model:

  • Update table.column with another table.column with common joined column

    - by Matt
    Hit a speed bump, trying to update some column values in my table from another table. This is what is supposed to happen when everything works Correct all the city, state entries in tblWADonations by creating an update statement that moves the zip city from the joined city/state zip field to the tblWADonations city state TBL NAME | COLUMN NAMES tblZipcodes with zip,city,State tblWADonations with zip,oldcity,oldstate This is what I have so far: UPDATE tblWADonations SET oldCity = tblZipCodes.city, oldState = tblZipCodes.state FROM tblWADonations INNER JOIN tblZipCodes ON tblWADonations.zip = tblZipCodes.zip Where oldCity <> tblZipcodes.city; There seems to be easy ways to do this online but I am overlooking something. Tried this by hand and in editor this is what it kicks back. Msg 8152, Level 16, State 2, Line 1 String or binary data would be truncated. The statement has been terminated. Please include a sql statement or where I need to make the edit so I can mark this post as a reference in my favorites. Thanks!

    I have an ASP.NET page in which there is a textbox. The user enters a string in the textbox and I want that string to be searched in Google and redirect the search results to my web page. I'm using VB as the background programming language. How can I do that? And also which toolbox control should I use in my page, for displaying the search results?

  • SQL CLR Assembly Error 80131051 when late binding to a registered C# COM .dll

    - by Shanubus
    I must have hit an unusual one, because I can't find any reference to this specific failing anywhere... Scenario: I have a legacy SQL function used to transform(encrypt) data. This function is called from within many stored procedures used by multiple applications. I say this, because the obvious answer of 'just call it from your code' is not really an option (or at least one I'd prefer not explore). The legacy function used sp_OA with an ActiveX dll on SQL2000 to perform its work. The new function is targeted at SQL2008 x64. I am ditching the sp_OA call in favor of CLR assembly; and am getting rid of the ActiveX dll and using a COM+ .dll (3rd party) to perform the same work. This 3rd party COM+ is required to be used based on spec given to me, so can't get rid of this piece either. Problem: After multiple attempts at getting this to work I have eliminated the following approaches 1) Create a Sql Assembly to call the local COM+ directly -- Can't do this as it requires a reference to System.EnterpriseServices. Including this requires that a whole slew of unsupported assemblies be registered which I don't want. The COM+ requires it's methods to be accessed via an Interface, so my attempts at late binding to it directly have not been successful (late binding would allow me to drop the unsupported references). 2) Create a Sql Assembly which references a C# class library that then calls the COM+. -- Same issue as #1; since the referenced dll uses System.EnterpriseServices and will be added as a dependency when referenced in the Sql Assembly, again trying to load all the unsupported libraries 3) Create a Sql Assembly which late binds to an ActiveX COM dll that calls the COM+. -- Worked in my dev environment, but can't go to x64 in production with ActiveX dll's written in VB6 (not to mention I hate backtracking anyway)... again failure... I am now onto an approach that is almost working, with of course one last hangup. I now have -a Sql Assembly that late binds to a C# COM dll, eliminating the need for including System.EnterpriseServices and eliminating the need to reference the C# COM in the SqlAssembly itself. The C# COM does reference System.EnterpriseServices to call the COM+, but since I am late binding to it from the SqlAssembly, I bypass the need for Sql to actually load them as referenced assemblies. Works in debugger.. Works on my dev box when the SqlAssembly dll is referenced in a test console app and called directly Installs to Sql2008 just fine Executing the actual UDF works, but returns no data due to a failure reporting from the late bound dll! So the SqlAssembly is instanciated just fine. It actually fails on it's late binding to the C# COM, which is working from a test console app on the same machine. It appears to be a difference in behavior based on whether called from within the SQL UDF or not. Since it is working on the same box from my console app, I am assuming it's on the SQL side. My steps to install were. --Install the COM+ dll and ensure it can be called successfully (as from with in the console app) --Register the C# COM dll (which calls the COM+) and get it to the GAC (again proofed to be working from console app) --Create my Assymetric Key CREATE ASYMMETRIC KEY SqlCryptoKey FROM EXECUTABLE FILE = 'D:\SqlEx.dll' CREATE LOGIN SqlExLogin FROM ASYMMETRIC KEY SqlExKey GRANT UNSAFE ASSEMBLY TO SqlExLogin GO --Add the assembly CREATE ASSEMBLY SqlEx FROM 'D:\SqlEx.dll' WITH PERMISSION_SET = UNSAFE; GO --Create the function CREATE FUNCTION dbo.f_SqlEx( @clearText [nvarchar](512) ) RETURNS nvarchar(512) WITH EXECUTE AS CALLER AS EXTERNAL NAME SqlEx.[SqlEx.SqlEx].Ex GO With all that done, I can now call my function SELECT dbo.f_SqlEx('test') But get this error in the event log... Retrieving the COM class factory for component with CLSID {F69D6320-5884-323F-936A-7657946604BE} failed due to the following error: 80131051. I can't really provide direct code examples, due to internal security implications; but all the code itself seems to work, I am suspecting perms or something of the like... I just find it odd that I can't find any reference to error 80131051. If someone out there believe some 'indirect' code samples will help, I will be happy to provide. Any assistance is appreciated.

  • Using RegEx to replace invalid characters

    - by yeahumok
    Hello I have a directory with lots of folders, subfolder and all with files in them. The idea of my project is to recurse through the entire directory, gather up all the names of the files and replace invalid characters (invalid for a SharePoint migration). However, i'm completely unfamiliar with Regular Expressions. The characters i need to get rid in filenames are: ~, #, %, &, *, { } , \, /, :, <, ?, -, | and "" I want to replace these characters with a blank space. I was hoping to use a string.replace() method to look through all these file names and do the replacement. So far, the only code i've gotten to is the recursion. I was thinking of the recursion scanning the drive, fetching the names of these files and putting them in a List. Can anybody help me with how to find/replace invalid chars with RegEx with those specific characters?

  • Test and Production Server

    - by Mike Silvis
    I am using Git for a test and production server and I'm trying to figure out the best way to update the production server. I have limited SSH access, and don't want to manually update my production server using FTP. I essentially would like to just be able to run a simple command and have the whole production server files match my dev. It is also important to note that users will be uploading images, and other files to our production server only, that we can not lose. Thanks,any help is appreciated

  • What's the shebang in Facebook URLs for?

    - by BoltClock
    I've just noticed that the long, convoluted Facebook URLs that we're used to now look like this: http://www.facebook.com/example.profile#!/pages/Some-Other-Page/123456789012345 As far as I can recall, earlier this year it was just a normal URL-fragment-like string (starting with #), without the exclamation mark. But now it's a shebang (#!), which I've previously only seen in shell scripts and Perl scripts. Does #! now play some special role in URLs, like for a certain Ajax framework or something since Facebook's interface is now largely Ajaxified? Or is it for some other purpose?

  • how to swap array-elements to transfer the array from a column-like into a row-like representation

    - by Christian Ammer
    For example: the array a1, a2, a3, b1, b2, b3, c1, c2, c3, d1, d2, d3 represents following table a1, b1, c1, d1 a2, b2, c2, d2 a3, b3, c3, d3 now i like to bring the array into following form a1, b1, c1, d1, a2, b2, c2, d2, a3, b3, c3, d3 Does an algorithm exist, which takes the array (from the first form) and the dimensions of the table as input arguments and which transfers the array into the second form? I thougt of an algorithm which doesn't need to allocate additional memory, instead i think it should be possible to do the job with element-swap operations.

  • jQuery encoding values differently than expected for jQuery.ajax data elements

    - by Adam Tuttle
    I'm using jQuery.ajax() to make a PUT request to a REST web service, but seeing some really strange serialization behavior. (Before you say it: Yes, I know that not all browsers support PUT -- this is just an example implementation for an api/framework, and ultimately will not be called by a browser, but rather by a server-side library that does support the extra http verbs.) Here's the form: <form action="/example/api/artist" method="put" id="update"> First Name: <input type="text" name="firstname" /><br/> Last Name: <input type="text" name="lastname" /><br/> Address: <input type="text" name="address" /><br/> City: <input type="text" name="city" /><br/> State: <input type="text" name="state" /><br/> Postal Code: <input type="text" name="postalcode" /><br/> Email: <input type="text" name="email" /><br/> Phone: <input type="text" name="phone" /><br/> Fax: <input type="text" name="fax" /><br/> Password: <input type="text" name="thepassword" /><br/> <input type="hidden" name="debug" value="true" /> <input type="submit" value="Update Artist" /> <input type="reset" value="Cancel" id="updateCancel" /> </form> And the JS: $("#update").submit(function(e){ e.preventDefault(); var frm = $(this); $.ajax({ url: frm.attr('action'), data:{ firstname: $("#update input[name=firstname]").val(), lastname: $("#update input[name=lastname]").val(), address: $("#update input[name=address]").val(), city: $("#update input[name=city]").val(), state: $("#update input[name=state]").val(), postalcode: $("#update input[name=postalcode]").val(), email: $("#update input[name=email]").val(), phone: $("#update input[name=phone]").val(), fax: $("#update input[name=fax]").val(), thepassword: $("#update input[name=thepassword]").val() }, type: frm.attr('method'), dataType: "json", contentType: "application/json", success: function (data, textStatus, xhr){ console.log(data); reloadData(); }, error: function (xhr, textStatus, err){ console.log(textStatus); console.log(err); } }); }); When using FireBug, I see the request go through as this: firstname=Austin&lastname=Weber&address=25463+Main+Street%2C+Suite+C&city=Berkeley&state=CA&postalcode=94707-4513&email=austin%40life.com&phone=555-513-4318&fax=510-513-4888&thepassword=nopolyes That's not horrible, but ideally I'd rather get %20 instead of + for spaces. I tried wrapping each field value lookup in an escape: firstname: escape($("#update input[name=firstname]").val()) But that makes things worse: firstname=Austin&lastname=Weber&address=25463%2520Main%2520Street%252C%2520Suite%2520C&city=Berkeley&state=CA&postalcode=94707-4513&email=austin%40life.com&phone=555-513-4318&fax=510-513-4888&thepassword=nopolyes In this case, the value is being escaped twice; so first the space is encoded to %20, and then the % sign is escaped to %25 resulting in the %2520 for spaces, and %252C for the comma in the address field. What am I doing wrong here?

  • SQL Server connection identification

    - by andrew007
    Hi, I have several developers which connect to production and test servers where we have DBs with similar names and structures. In SSMS there are info related to the connection, but sometimes are not properly displayed and/or hidden. I know that it is possible to customize the status bar of each connection in SSMS, but how do you ensure that your developer is connecting to the right server before he runs a query? Is there any way to handle this? THANKS!

  • Integrating YUI tests with CruiseControl

    - by Dan R
    I am using YUI to test my JavaScript app, and want to integrate the test results into my CruiseControl build system. How can I use CruiseControl to run the tests? I initially thought about using the JUnit plugin to drive the tests, but that is a no go. Does anyone else have this working? (Please note: Changing either YUI or CruiseControl isn't an option for me.)

  • Efficient determination of which strings in an array are substrings of the others?

    - by byte
    In C#, Say you have an array of strings, which contain only characters '0' and '1': string[] input = { "0101", "101", "11", "010101011" }; And you'd like to build a function: public void IdentifySubstrings(string[] input) { ... } That will produce the following: "0101 is a substring of 010101011" "101 is a substring of 0101" "101 is a substring of 010101011" "11 is a substring of 010101011" And you are NOT able to use built-in string functionality (such as String.Substring). How would one efficiently solve this problem? Of course you could plow through it via brute force, but it just feels like there ought to be a way to accomplish it with a tree (since the only values are 0's and 1's, it feels like a binary tree ought to fit somehow). I've read a little bit about things like suffix trees, but I'm uncertain if that's the right path to be going down. Any efficient solutions you can think of?

  • Reconstruction of java command line arguments

    Is there a way to reconstruct the command line arguments passed to Java within a Java program, including the JVM options and classpath option? I have a Java program that needs to restart the JVM and manipulate its bootclasspath (i.e. trying to override some system classes). I use the libc system method to invoke the new JVM. I'm open for better approaches, but Java agents isn't an option.

  • Is there a WPF "WrapGrid" control available or an easy way to create one?

    - by Jason Coyne
    Essentially I want a wrapPanel, but I would like items to snap to a grid rather than be pressed up to the left, so I can get a nice uniform looking grid, that automatically consumes available space. WrapPanel handles the resize part. WPF.Contrib.AutoGrid handles a nice automatic grid. Anyone got a control that combines them? My use case is I have a series of somewhat irregularly shaped controls. I would like them to appear in nice columns so the wrap panel should snap to the next "tabstop" when placing a control
