Why do I get "Error 6060" when I try to use DBD::Advantage with a 64-bit perl on Linux?

- by WarheadsSE

I realize that I am attempting to go beyond the "supported" behavior of the manf's released drivers for Perl, after all they have only released it in package with x86 .so's. However, since I cannot use their package with x64 Perl on a RHEL 5.4 x86_64 box, and maintaining a seperate install of x86 Perl just for this one package, I have made an attempt to get this puppy working thanks to released 64-bit .so's that accompany other driver packages for Advantage. What I have done to this point: download beta 10 DBI drivers, in 32 download beta 10 PHP extension (it contains 32 and x86_64) copy the required DLLs into the ads-lib location (eg /usr/local/ads/lib64) compile the Perl DBI driver with the path to the lib64's .so's Good compilation, good install, good use. The problem is that I always get : failed: [iAnywhere Solutions][Advantage SQL][ASA] Error 6060: Advantage Database Server not available on specified server. axServerConnect (SQL-HY000)(DBD: db_login/SQLConnect err=-1) Does anyone have any ideas? EDIT: fixed package name in post title EDIT: Updated title. It appears that it's not just the x64 perl, but the RHEL 5.4 underneath that may be interfering. As commented below, I managed to shoe-horn a x86 perl onto the system, and compile the DBD::Advantage 9.99, and later replacing that with 9.10, and none of these x86 would connect either. Neither library (9.99 or 9.10) in either bit-edness will connect from this x86_64 server to the windows server's UNC path. I have successfully mounted this share without problems, but still I cannot seem to connect to the 9.1. I have tried: \hostname\PATH \FQDN\PATH \IP\PATH and all of these variations with the port (default) 6262 included. My windows machine connects fine, with both 9.1 and 9.99 from strawberry perl.

Javascript with Django?

- by Rosarch

I know this has been asked before, but I'm having a hard time setting up JS on my Django web app, even though I'm reading the documentation. I'm running the Django dev server. My file structure looks like this: mysite/ __init__.py MySiteDB manage.py settings.py urls.py myapp/ __init__.py admin.py models.py test.py views.py templates/ index.html Where do I want to put the Javascript and CSS? I've tried it in a bunch of places, including myapp/, templates/ and mysite/, but none seem to work. From index.html: <head> <title>Degree Planner</title> <script type="text/javascript" src="/scripts/JQuery.js"></script> <script type="text/javascript" src="/media/scripts/sprintf.js"></script> <script type="text/javascript" src="/media/scripts/clientside.js"></script> </head> From urls.py: (r'^admin/', include(admin.site.urls)), (r'^media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': 'media'}) (r'^.*', 'mysite.myapp.views.index'), I suspect that the serve() line is the cause of errors like: TypeError at /admin/auth/ 'tuple' object is not callable Just to round off the rampant flailing, I changed these settings in settings.py: MEDIA_ROOT = '/media/' MEDIA_URL = 'http://127.0.0.1:8000/media'

In Python BeautifulSoup How to move tags

- by JJ

I have a partially converted XML document in soup coming from HTML. After some replacement and editing in the soup, the body is essentially - <Text...></Text> # This replaces <a href..> tags but automatically creates the </Text> <p class=norm ...</p> <p class=norm ...</p> <Text...></Text> <p class=norm ...</p> and so forth. I need to "move" the <p> tags to be children to <Text> or know how to suppress the </Text>. I want - <Text...> <p class=norm ...</p> <p class=norm ...</p> </Text> <Text...> <p class=norm ...</p> </Text> I've tried using item.insert and item.append but I'm thinking there must be a more elegant solution. for item in soup.findAll(['p','span']): if item.name == 'span' and item.has_key('class') and item['class'] == 'section': xBCV = short_2_long(item._getAttrMap().get('value','')) if currentnode: pass currentnode = Tag(soup,'Text', attrs=[('TypeOf', 'Section'),... ]) item.replaceWith(currentnode) # works but creates end tag elif item.name == 'p' and item.has_key('class') and item['class'] == 'norm': childcdatanode = None for ahref in item.findAll('a'): if childcdatanode: pass newlink = filter_hrefs(str(ahref)) childcdatanode = Tag(soup, newlink) ahref.replaceWith(childcdatanode) Thanks

javascript onmouseover hide a div block

- by Loki

SO this is my code so far: JS: <script type="text/javascript"> function Hide(srcField) { var x = srcField.getAttribute('name'); var string = new RegExp("hide_ID",'gi'); switch (x) { case "1": var dataRows= document.getElementsByID("obrazovanje"); alert (dataRows[0].innerHTML); dataRows[0].className.replace('',string); break; case "2": var dataRows= document.getElementsByID("rad_iskustvo"); dataRows[0].className.replace('',string); break; case "3": var dataRows= document.getElementsByID("strani_jezici"); dataRows[0].className.replace('',string); break; case "4": var dataRows= document.getElementsByID("znanja_vjestine"); dataRows[0].className.replace('',string); break; case "5": var dataRows= document.getElementsByID("osobine_interesi"); dataRows[0].className.replace('',string); break; } } </script> CSS: .hide_ID, { display:none } HTML: <a name="1"><h4><span name="1" onmouseover="Hide(this)">OBRAZOVANJE:</span></h4></a> <div ID="obrazovanje"> <ul> <li>2001.-2005. elektrotehnicar</li> <li>2009.-2012. racunarstvo</li> </ul> </div> the idea is that i want to hide the div block when i hover over the title that's in h4, but it doesn't seem to hide it... any ideas? i started using replace but it still didn't work, before that it was just 'dataRows[0].className = "hide_ID"' but that didn't work either.

WCF object parameter loses values

- by Josh

I'm passing an object to a WCF service and wasn't getting anything back. I checked the variable as it gets passed to the method that actually does the work and noticed that none of the values are set on the object at that point. Here's the object: [DataContract] public class Section { [DataMember] public long SectionID { get; set; } [DataMember] public string Title { get; set; } [DataMember] public string Text { get; set; } [DataMember] public int Order { get; set; } } Here's the service code for the method: [OperationContract] public List<Section> LoadAllSections(Section s) { return SectionRepository.Instance().LoadAll(s); } The code that actually calls this method is this and is located in a Silverlight XAML file: SectionServiceClient proxy = new SectionServiceClient(); proxy.LoadAllSectionsCompleted += new EventHandler<LoadAllSectionsCompletedEventArgs>(proxy_LoadAllSectionsCompleted); Section s = new Section(); s.SectionID = 4; proxy.LoadAllSectionsAsync(s); When the code finally gets into the method LoadAllSections(Section s), the parameter's SectionID is not set. I stepped through the code and when it goes into the generated code that returns an IAsyncResult object, the object's properties are set. But when it actually calls the method, LoadAllSections, the parameter received is completely blank. Is there something I have to set to make the proeprty stick between method calls?

Triple Quotes? How do I delimit a databound Javascript string parameter in ASP.NET?

- by David HAust

How do I delimit a Javascript databound string parameter in an anchor OnClick event? I have an anchor tag in an ASP.NET Repeater control. The OnClick event of the anchor contains a call to a Javascript function. The Javascript funciton takes a string for it's input parameter. The string parameter is populated with a databound value from the Repeater. I need the 'double quotes' for the Container.DataItem. I need the 'single quotes' for the OnClick. And I still need one more delimiter (triple quotes?) for the input string parameter of the Javascript function call. Since I can't use 'single quotes' again, how do I ensure the Javascript function knows the input parameter is a string and not an integer? Without the extra quotes around the input string parameter, the Javascript function thinks I'm passing in an integer. Cheers in advance for any knowledge you can drop. The anchor: <a id="aShowHide" onclick='ToggleDisplay(<%# DataBinder.Eval(Container.DataItem, "JobCode") %>);' >Show/Hide</a> and here is the Javascript: <script language="JavaScript" type="text/javascript">/* Shows/Hides the Jobs Div */ function ToggleDisplay(jobCode) { /* Each div has it's ID set dynamically ('d' plus the JobCode) */ var elem = document.getElementById('d' + jobCode); if (elem) { if (elem.style.display != 'block') { elem.style.display = 'block'; elem.style.visibility = 'visible'; } else { elem.style.display = 'none'; elem.style.visibility = 'hidden'; } } }</script>

silverlight 3: long running wcf call triggers 401.1 (access denied)

- by sympatric greg

I have a wcf service consumed by a silverlight 3 control. The Silverlight client uses a basicHttpBindinging that is constructed at runtime from the control's initialization parameters like this: public static T GetServiceClient<T>(string serviceURL) { BasicHttpBinding binding = new BasicHttpBinding(Application.Current.Host.Source.Scheme.Equals("https", StringComparison.InvariantCultureIgnoreCase) ? BasicHttpSecurityMode.Transport : BasicHttpSecurityMode.None); binding.MaxReceivedMessageSize = int.MaxValue; binding.MaxBufferSize = int.MaxValue; binding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly; return (T)Activator.CreateInstance(typeof(T), new object[] { binding, new EndpointAddress(serviceURL)}); } The Service implements windows security. Calls were returning as expected until the result set increased to several thousand rows at which time HTTP 401.1 errors were received. The Service's HttpBinding defines closeTime, openTimeout, receiveTimeout and sendTimeOut of 10 minutes. If I limit the size of the resultset the call suceeds. Additional Observations from Fiddler: When Method2 is modified to return a smaller resultset (and avoid the problem), control initialization consists of 4 calls: Service1/Method1 -- result:401 Service1/Method1 -- result:401 (this time header includes element "Authorization: Negotiate TlRMTV..." Service1/Method1 -- result:200 Service1/Method2 -- result:200 (1.25 seconds) When Method2 is configured to return the larger resultset we get: Service1/Method1 -- result:401 Service1/Method1 -- result:401 (this time header includes element "Authorization: Negotiate TlRMTV..." Service1/Method1 -- result:200 Service1/Method2 -- result:401.1 (7.5 seconds) Service1/Method2 -- result:401.1 (15ms) Service1/Method2 -- result:401.1 (7.5 seconds)

bash: listing files in date order, with spaces in filenames

- by Jason Judge

I am starting with a file containing a list of hundreds of files (full paths) in a random order. I would like to list the details of the ten latest files in that list. This is my naive attempt: ls -las -t `cat list-of-files.txt` | head -10 That works, so long as none of the files have spaces in, but fails if they do as those files are split up at the spaces and treated as separate files. I have tried quoting the files in the original list-of-files file, but the here-document still splits the files up at the spaces in the filenames. The only way I can think of doing this, is to ls each file individually (using xargs perhaps) and create an intermediate file with the file listings and the date in a sortable order as the first field in each line, then sort that intermediate file. However, that feels a bit cumbersome and inefficient (hundreds of ls commands rather than one or two). But that may be the only way to do it? Is there any way to pass "ls" a list of files to process, where those files could contain spaces - it seems like it should be simple, but I'm stumped.

UpdateAllViews() from within a worker thread?

- by Harvey

I have a worker thread in a class that is owned by a ChildView. (I intend to move this to the Doc eventually.) When the worker thread completes a task I want all the views to be updated. How can I make a call to tell the Doc to issue an UpdateAllViews()? Or is there a better approach? Thank you. Added by OP: I am looking for a simple solution. The App is running on a single user, single CPU computer and does not need network (or Internet) access. There is nothing to cause a deadlock. I think I would like to have the worker thread post (or send) a message to cause the views to update. Everything I read about threading seems way more complicated than what I need - and, yes, I understand that all those precautions are necessary for applications that are running in multiprocessor, multiuser, client-server systems, etc. But none of those apply in my situation. I am just stuck at getting the right combination of getting the window handle, posting the message and responding to the message in the right functions and classes to compile and function at all.

Perl WordPress::XMLRPC categories not being set.

- by Jay

The following code works fine to upload a new post to a WordPress blog but for the life of me I can't seem to get the categories to be set. The categories exist. I've tried all lower case, tried case-matching, tried the slug version. Nothing works. No matter how I try passing the categories, the post gets assigned only to the default category. I've scoured the web to find other pieces of sample code and none mention the actual code semantics of how to assign post to certain categories using the WordPress::XMLRPC module. use WordPress::XMLRPC; my $o = WordPress::XMLRPC-new; $o-username('username'); $o-password('password'); $o-proxy('http://blogdomain.com/xmlrpc.php'); $o-server() || die "$!"; my $hashref = { 'title' = 'Test New Post 999 555456782', 'categories' = ['Categorie1', 'Categorie2'], 'description' = '<pHere is the content</p', 'mt_keywords' = 'tag1, tag2, tag3', 'mt_allow_comments' = 1, }; my $ID = $o-newPost($hashref, 1);

Sharing session variables from http and https versio

- by tangurena

I am trying to fix an ASP.NET site that a friend had botched converting from older technologies. To the user, the site appears to have public and secured sections. Behind the scenes, the public and private sites are separate web applications with separate app pools. The difficulty arises because it appears that the applications share the same session IDs (when going from the public to the secured pages, the session ID remains the same), yet none of the (InProc) session variables are getting passed from the public site to the private one. Basically, the workflow consists of the user checking a checkbox ("I agree" type of stuff) on the public site (let's call that page http://www.boring.gov/iAgree.aspx), then logging in on the secured site (let's call that page https://www.boring.gov/login.aspx). The commandments from the parent agency in DC are that the user may not bookmark the login page, the user has to click "I agree" every time they log in, and that the "I agree" stuff has to be on a separate page. What am I missing? How would you do it? Notes: 1 - This is getting hosted on a single Windows 2003 server. 2 - Yes, it is a government agency. 3 - I would have done things very differently if I was doing the conversion, but I wasn't brought in until the poop hit the fan, and it is too late to redo things. 4 - Two previous SO threads that appear to be related, yet don't apply are this and that

Visual Studio 2008 / ASP.NET 3.5 / C# -- issues with intellisense, references, and builds

- by goober

Hey all, Hoping you can help me -- the strangest thing seems to have happened with my VS install. System config: Windows 7 Pro x64, Visual Studio 2008 SP1, C#, ASP.NET 3.5. I have two web site projects in a solution. I am referencing NUnit / NHibernate (did this by right-clicking on the project and selecting "Add Reference". I've done this for several projects in the past). Things were working fine but recently stopped working and I can't figure out why. Intellisense completely disappears for any files in my App_Code directory, and none of the references are recognized (they are recognized by any file in the root directory of the web site project. Additionally, pretty simple commands like the following (in Page_Load) fail (assume TextBox1 is definitely an element on the page): if (Page.IsPostBack) { str test1; test1 = TextBox1.Text; } It says that all the page elements are null or that it can't access them. At first I thought it was me, but due to the combination of issues, it seems to be Visual Studio itself. I've tried clearing the temp directories & rebuilding the solution. I've also tried tools -- options -- text editor settings to ensure intellisense is turned on. I'd appreciate any help you can give! Thanks, Sean

Is it just me? I find LINQ to XML to be sort of cumbersome, compared to XPath.

- by Cheeso

I am a C# programmer, so I don't get to take advantage of the cool XML syntax in VB. Dim itemList1 = From item In rss.<rss>.<channel>.<item> _ Where item.<description>.Value.Contains("LINQ") Or _ item.<title>.Value.Contains("LINQ") Using C#, I find XPath to be easier to think about, easier to code, easier to understand, than performing a multi-nested select using LINQ to XML. Look at this syntax, it looks like Greek swearing: var waypoints = from waypoint in gpxDoc.Descendants(gpx + "wpt") select new { Latitude = waypoint.Attribute("lat").Value, Longitude = waypoint.Attribute("lon").Value, Elevation = waypoint.Element(gpx + "ele") != null ? waypoint.Element(gpx + "ele").Value : null, Name = waypoint.Element(gpx + "name") != null ? waypoint.Element(gpx + "name").Value : null, Dt = waypoint.Element(gpx + "cmt") != null ? waypoint.Element(gpx + "cmt").Value : null }; All the casting, the heavy syntax, the possibility for NullPointerExceptions. None of this happens with XPath. I like LINQ in general, and I use it on object collections and databases, but my first go-round with querying XML led me right back to XPath. Is it just me? Am I missing something? EDIT: someone voted to close this as "not a real question". But it is a real question, stated clearly. The question is: Am I misunderstanding something with LINQ to XML?

Eclipse+PyDev+GAE memcache error

- by bocco

I've started using Eclipe+PyDev as an environment for developing my first app for Google App Engine. Eclipse is configured according to this tutorial. Everything was working until I start to use memcache. PyDev reports the errors and I don't know how to fix it: Error: Undefined variable from import: get How to fix this? Sure, it is only PyDev checker problem. Code is correct and run on GAE. UPDATE: I'm using PyDev 1.5.0 but experienced the same with 1.4.8. My PYTHONPATH includes (set in Project Properties/PyDev - PYTHONPATH): C:\Program Files\Google\google_appengine C:\Program Files\Google\google_appengine\lib\django C:\Program Files\Google\google_appengine\lib\webob C:\Program Files\Google\google_appengine\lib\yaml\lib UPDATE 2: I took a look at C:\Program Files\Google\google_appengine\google\appengine\api\memcache\__init__.py and found get() is not declared as memcache module function. They use the following trick to do that (I didn't hear about such possibility): _CLIENT = None def setup_client(client_obj): """Sets the Client object instance to use for all module-level methods. Use this method if you want to have customer persistent_id() or persistent_load() functions associated with your client. Args: client_obj: Instance of the memcache.Client object. """ global _CLIENT var_dict = globals() _CLIENT = client_obj var_dict['set_servers'] = _CLIENT.set_servers var_dict['disconnect_all'] = _CLIENT.disconnect_all var_dict['forget_dead_hosts'] = _CLIENT.forget_dead_hosts var_dict['debuglog'] = _CLIENT.debuglog var_dict['get'] = _CLIENT.get var_dict['get_multi'] = _CLIENT.get_multi var_dict['set'] = _CLIENT.set var_dict['set_multi'] = _CLIENT.set_multi var_dict['add'] = _CLIENT.add var_dict['add_multi'] = _CLIENT.add_multi var_dict['replace'] = _CLIENT.replace var_dict['replace_multi'] = _CLIENT.replace_multi var_dict['delete'] = _CLIENT.delete var_dict['delete_multi'] = _CLIENT.delete_multi var_dict['incr'] = _CLIENT.incr var_dict['decr'] = _CLIENT.decr var_dict['flush_all'] = _CLIENT.flush_all var_dict['get_stats'] = _CLIENT.get_stats setup_client(Client()) Hmm... Any idea how to force PyDev to recognize that?

Get available screen area in autohotkey

- by Herms

I'm trying to write a few simple AutoHotkey scripts for moving windows around, and I'm having trouble getting the correct screen size values. I'm trying to get the size of the usable area on the screen (generally the full screen resolution minus the taskbar, and maybe any other docked windows like the sidebar in Vista). Neither of the methods I've found for getting the screen width seems to work. None of the 3 methods I found to get the screen size are giving me the right values. Here's the test script I'm using (running on XP with the taskbar on the bottom at its default size): #7:: WinMove A,,0,0,A_ScreenWidth,A_ScreenHeight return #8:: ;SM_CXMAXIMIZED and SM_CYMAXIMIZED SysGet, ScreenWidth, 61 SysGet, ScreenHeight, 62 WinMove A,,0,0,ScreenWidth,ScreenHeight return #9:: ;SM_CXFULLSCREEN and SM_CYFULLSCREEN SysGet, ScreenWidth, 16 SysGet, ScreenHeight, 17 WinMove A,,0,0,ScreenWidth,ScreenHeight return #7 causes the window to take up the entire resolution, so it overlaps the taskbar. #8 causes the width to be larger than the resolution (I see the window's right edge show up on my secondary monitor) and the height is slightly too large, so the window partially overlaps the taskbar area. Looks like this is correct except for not taking into account the window decorations at the edges. #9 seems to have the correct width, but the height is too short. It looks like it's subtracting the taskbar's height from the resolution's height, but then subtracting another 30 pixels from it. I could just use what I have in #9 and add 30 to the height I get, but that feels too much like a hack that would break in other configurations. It seems like there has to be a way to get the available screen size properly, but I can't find it in AutoHotkey. For reference, this seems to give me what I need in Java: Toolkit.getDefaultToolkit().getScreenSize();

what's an effective way to build a csproj file in code?

- by jcollum

I'd like to avoid a command line for this. I've been using the MSBuild API ( Microsoft.Build.Framework and Microsoft.Build.BuildEngine) with code that looks like this: this.buildEngine = new Engine(); BuildPropertyGroup props = new BuildPropertyGroup(); props.SetProperty("Configuration", "Debug"); this.buildEngine.RegisterLogger(this.logger); Project proj = new Project(this.buildEngine); proj.LoadXml(this.projectFileAndPath, ProjectLoadSettings.None); this.buildEngine.BuildProject(proj, "Build"); However I've run into enough problems that I can't find answers for that I'm really wondering if I'm doing this right. First, I can't find the output (there's no bin directory in any of the places where I figured the dll's would end up). Second, I tried building a project that I had made in VS2008 and the line proj.LoadXml( fails for invalid xml encoding. But of course the xml file is valid, since VS2008 can build it (I checked). At this point I'm beginning to wonder if I've picked up some code that's way out of date or a methodology that's been superseded by something else. Opinions?

Localizing DataAnnotations Custom Validator

- by Gabe G

Hello SO, I'm currently working in an MVC 2 app which has to have everything localized in n-languages (currently 2, none of them english btw). I validate my model classes with DataAnnotations but when I wanted to validate a DateTime field found out that the DataTypeAttribute returns always true, no matter it was a valid date or not (that's because when I enter a random string "foo", the IsValid() method checks against "01/01/0001 ", dont know why). Decided to write my own validator extending ValidationAtribute class: public class DateTimeAttribute : ValidationAttribute { public override bool IsValid(object value) { DateTime result; if (value.ToString().Equals("01/01/0001 0:00:00")) { return false; } return DateTime.TryParse(value.ToString(), out result); } } Now it checks OK when is valid and when it's not, but my problem starts when I try to localize it: [Required(ErrorMessageResourceType = typeof(MSG), ErrorMessageResourceName = "INS_DATA_Required")] [CustomValidation.DateTime(ErrorMessageResourceType = typeof(MSG), ErrorMessageResourceName = "INS_DATA_DataType")] public DateTime INS_DATA { get; set; } If I put nothing in the field I get a localized MSG (MSG being my resource class) for the key=INS_DATA_Required but if I put a bad-formatted date I get the "The value 'foo' is not valid for INS_DATA" default message and not the localized MSG. What am I misssing?

Does height and width not apply to span?

Total noob question, but here. CSS .product__specfield_8_arrow { /*background-image:url(../../upload/orng_bg_arrow.png); background-repeat:no-repeat;*/ background-color:#fc0; width:50px !important; height:33px !important; border: 1px solid #dddddd; border-left:none; border-radius:5px; -moz-border-radius:5px; -webkit-border-radius:5px; border-bottom-left-radius:0px; border-top-left-radius:0px; -moz-border-radius-bottomleft:0px; -moz-border-radius-topleft:0px; -webkit-border-bottom-left-radius:0px; -webkit-border-top-left-radius:0px; margin:0; padding:2px; cursor:pointer; }??? HTML <span class="product__specfield_8_arrow"> </span>? Fiddle Basically I'm trying to emulate a button, make a span (or something) look like a button next to an input field that actually doesn't need to be one because of an auto fill generator that generates errors onEnter. Thought this'd be a quick fix for now but obviously not. Thanks.

How to gray out HTML form inputs?

- by typoknig

What is the best way to gray out text inputs on an HTML form? I need the inputs to be grayed out when a user checks a check box. Do I have to use JavaScript for this (not very familiar with JScript) or can I use PHP (which I am more familiar with)? EDIT: After some reading I have got a little bit of code, but it is giving me problems. For some reason I cannot get my script to work based on the state of the form input (enabled or disabled) or the state of my checkbox (checked or unchecked), but my script works fine when I base it on the values of the form inputs. I have written my code exactly like several examples online (mainly this one) but to no avail. None of the stuff that is commented out will work. What am I doing wrong here? <label>Mailing address same as residental address</label> <input name="checkbox" onclick="disable_enable() "type="checkbox" style="width:15px"/><br/><br/> <script type="text/javascript"> function disable_enable(){ if (document.form.mail_street_address.value==1) document.form.mail_street_address.value=0; //document.form.mail_street_address.disabled=true; //document.form.mail_city.disabled=true; //document.form.mail_state.disabled=true; //document.form.mail_zip.disabled=true; else document.form.mail_street_address.value=1; //document.form.mail_street.disabled=false; //document.form.mail_city.disabled=false; //document.form.mail_state.disabled=false; //document.form.mail_zip.disabled=false; } </script>

Rijndael managed: plaintext length detction

Return msEncrypt.ToArray() End Function Here's the actual code I am calling encryptBytesToBytes_AES() with: Private Sub btnEncrypt_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEncrypt.Click Dim bZeroKey As Byte() = {&H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0, &H0} PrintBytesToRTF(encryptBytesToBytes_AES(bZeroKey, bZeroKey, bZeroKey)) End Sub However, I get an exception thrown on swEncrypt.Write(plainText) stating that the 'Length of the data to encrypt is invalid.' However, I know that the size of my key, iv, and plaintext are 16 bytes == 128 bits == aesAlg.BlockSize. Why is it throwing this exception? Is it because the StreamWriter is trying to make a String (ostensibly with some encoding) and it doesn't like &H0 as a value?

Javascript doesnt update

- by Trikam

Hi all, I have a function that passes a parameter which is a function call and then i use setTimeout to call this passed function call. now i tried two methods with setTimout to raise the event and i used function.call(). When this passed parameter function call was raised none of the javascript was being updated, below is the javascript which im using to raise the event and the javascript which is supposed to be updated: The function being passed is [context] - function() { ErrorMessageFileSelect('diverrortextchoosechannal','The file chosen is to big, you must choose a file less than 1MB'); } function FileSizeOnLoad(contentLength,context) { if (context != null) { // context.call(); setTimeout(context,0); // or context.call(); } else { $('#inputHiddenFileSizeField').val(contentLength); DisplayChoseFileInformation(contentLength); } } //this is where the update should happen function ErrorMessageFileSelect(className, errorMessage) { $('div.' + className).text(errorMessage); alert($('div.' + className).text()); } Is there somthing im missing, can someone help me with this issue please. Thanks

Writing fortran robust and "modern" code

- by Blklight

In some scientific environments, you often cannot go without FORTRAN as most of the developers only know that idiom, and there is lot of legacy code and related experience. And frankly, there are not many other cross-platform options for high performance programming ( C++ would do the task, but the syntax, zero-starting arrays, and pointers are too much for most engineers ;-) ). I'm a C++ guy but I'm stuck with some F90 projects. So, let's assume a new project must use FORTRAN (F90), but I want to build the most modern software architecture out of it. while being compatible with most "recent" compilers (intel ifort, but also including sun/HP/IBM own compilers) So I'm thinking of imposing: global variable forbidden, no gotos, no jump labels, "implicit none", etc. "object-oriented programming" (modules with datatypes + related subroutines) modular/reusable functions, well documented, reusable libraries assertions/preconditions/invariants (implemented using preprocessor statements) unit tests for all (most) subroutines and "objects" an intense "debug mode" (#ifdef DEBUG) with more checks and all possible Intel compiler checks possible (array bounds, subroutine interfaces, etc.) uniform and enforced legible coding style, using code processing tools C stubs/wrappers for libpthread, libDL (and eventually GPU kernels, etc.) C/C++ implementation of utility functions (strings, file operations, sockets, memory alloc/dealloc reference counting for debug mode, etc.) ( This may all seem "evident" modern programming assumptions, but in a legacy fortran world, most of these are big changes in the typical programmer workflow ) The goal with all that is to have trustworthy, maintainable and modular code. Whereas, in typical fortran, modularity is often not a primary goal, and code is trustworthy only if the original developer was very clever, and the code was not changed since then ! (i'm a bit joking here, but not much) I searched around for references about object-oriented fortran, programming-by-contract (assertions/preconditions/etc.), and found only ugly and outdated documents, syntaxes and papers done by people with no large-scale project involvement, and dead projects. Any good URL, advice, reference paper/books on the subject?

Tinymce mceToggleEditor scroll/focus issue

- by Lizard

I have 50+ textareas that I am using tinyMCE with. Instead of loading each one I am just initialising them, then activing them later on request Initialisation tinyMCE.init({ mode : "none", theme : "advanced", theme_advanced_buttons1 : "", theme_advanced_buttons2 : "", theme_advanced_buttons3 : "", theme_advanced_toolbar_location : false, theme_advanced_toolbar_align : "left", theme_advanced_statusbar_location : false, theme_advanced_resizing : true, auto_focus : false }); Edit Observer $('ul span.edit-details').click(function () { var id = this.id; id = id.replace('edit-',''); tinyMCE.execCommand('mceToggleEditor',false,'editor-'+id); }); UPDATE I have also tried $('ul span.edit-details').click(function () { var id = this.id; id = id.replace('edit-',''); if($('#details-'+id).is(":hidden")) { $('#details-'+id).show(); tinyMCE.execCommand('mceAddControl',false,'editor-'+id); } else { $('#details-'+id).hide(); tinyMCE.execCommand('mceRemoveControl',false,'editor-'+id); } }); The problem I have is that when tinyMCE.execCommand('mceToggleEditor',false,'editor-'+id); fires the pages focuses/scrolls to that textarea, even if it is already in the viewport. Any suggestions on how to stop this? Thanks!
