  • C# - InvalidCastException when fetching double from sqlite

    - by Irro
    I keep getting a InvalidCastException when I'm fetching any double from my SQLite database in C#. The exception says "Specified cast is not valid." I am able to see the value in a SQL manager so I know it exists. It is possible to fetch Strings (VARCHARS) and ints from the database. I'm also able to fetch the value as an object but then I get "66.0" when it's suppose to be "66,8558604947586" (latitude coordination). Any one who knows how to solve this? My code: using System.Data.SQLite; ... SQLiteConnection conn = new SQLiteConnection(@"Data Source=C:\\database.sqlite; Version=3;"); conn.Open(); SQLiteDataReader reader = getReader(conn, "SELECT * FROM table"); //These are working String name = reader.GetString(1); Int32 value = reader.GetInt32(2); //This is not working Double latitude = reader.getDouble(3); //This gives me wrong value Object o = reader[3]; //or reader["latitude"] or reader.getValue(3)

  • Umbraco XSLT issue

    - by Brad
    I'm trying to use the Umbraco GetMedia function to write an image URL to the screen, I receive an error parsing the XSLT file. <xsl:for-each select="$currentPage/descendant::node [string(data [@alias='tickerItemActive']) = '1']"> <xsl:value-of select="data [@alias='tickerText']"/><br /> <xsl:value-of select="umbraco.library:GetMedia(data [@alias='tickerImage'], 0)/data [@alias = 'umbracoFile']"/> </xsl:for-each> The tickerImage field contains the MediaID for which I'd like to display the URL. I can return the field outside the GetMedia function and it works fine. I can also replace the data [@alias='tickerImage] with '1117' (or any valid media ID) the XSLT passes verification and the script runs. THIS WORKS: <xsl:value-of select="umbraco.library:GetMedia('1117', 0)/data [@alias = 'umbracoFile']"/> THIS DOES NOT: <xsl:value-of select="umbraco.library:GetMedia(data [@alias='tickerImage'], 0)/data [@alias = 'umbracoFile']"/> Any help that can be offered would is appreciated. Thanks!

  • Styling an Input Field

    - by John
    Hello, How can I give the input field below the characteristics listed below? Characteristics: -Text typed into the field starts in the upper left corner and starts on another line (wraps?) when the right border of the field is reached. -A scroll bar appears if the text is more than what can fit into the field. -The text is in Courier font. Thanks in advance, John echo '<form action="http://www...com/sandbox/comments/comments2.php" method="post"> <input type="hidden" value="'.$_SESSION['loginid'].'" name="uid"> <input type="hidden" value="'.$submissionid.'" name="submissionid"> <input type="hidden" value="'.$submission.'" name="submission"> <label class="addacomment" for="title">Add a comment:</label> <input class="commentsubfield" name="comment" type="comment" id="comment" maxlength="1000"> <div class="commentsubbutton"><input name="submit" type="submit" value="Submit"></div> </form> '; Some relevant CSS: .commentsubfield {margin-left: 30px; margin-top: 30px; width: 390px; height: 90px; border: 1px solid #999999; padding: 5px; }

  • How to retain XML string as a string field during XML deserialization

    - by detale
    I got an XML input string and want to deserialize it to an object which partially retain the raw XML. <SetProfile> <sessionId>A81D83BC-09A0-4E32-B440-0000033D7AAD</sessionId> <profileDataXml> <ArrayOfProfileItem> <ProfileItem> <Name>Pulse</Name> <Value>80</Value> </ProfileItem> <ProfileItem> <Name>BloodPresure</Name> <Value>120</Value> </ProfileItem> </ArrayOfProfileItem> </profileDataXml> </SetProfile> The class definition: public class SetProfile { public Guid sessionId; public string profileDataXml; } I hope the deserialization syntax looks like string inputXML = "..."; // the above XML XmlSerializer xs = new XmlSerializer(typeof(SetProfile)); using (TextReader reader = new StringReader(inputXML)) { SetProfile obj = (SetProfile)xs.Deserialize(reader); // use obj .... } but XMLSerializer will throw an exception and won't output < profileDataXml 's descendants to "profileDataXml" field in raw XML string. Is there any way to implement the deserialization like that?

  • Regex: markdown-style link matching

    - by The.Anti.9
    I want to parse markdown style links, but I'm having some trouble matching the reference style ones. Like this one: [id]: http://example.com/ "Optional Title Here" My regex gets the id and the url, but not the title. Heres what I have: /\[([a-zA-Z0-9_-]+)\]: (\S+)\s?("".*?"")?/ I go through and add the references to a hashtable. the id as the key and the value is an instance of a class I made called LinkReference that just contains the url and the title. In case the problem is not my regex, and my code adding the matches to the hash table, Heres my code for that too: Regex rx = new Regex(@"\[([a-zA-Z0-9_-]+)\]: (\S+)\s?("".*?"")?"); MatchCollection matches = rx.Matches(InputText); foreach (Match match in matches) { GroupCollection groups = match.Groups; string title = null; try { title = groups[3].Value; } catch (Exception) { // keep title null } LinkReferences.Add(groups[1].Value, new LinkReference(groups[2].Value, title)); }

  • Automatic Adjusting Range Table

    - by Bradford
    I have a table with a start date range, an end date range, and a few other additional columns. On input of a new record, I want to automatically adjust any overlapping date ranges (shrinking them to allow for the new input). I also want to ensure that no overlapping records can accidentally be inserted into this table. I'm using Oracle and Java for my application code. How should I enforce the prevention of overlapping date ranges and also allow for automatically adjusting overlapping ranges? Should I create an AFTER INSERT trigger, with a dbms_lock to serialize access, to prevent the overlapping data. Then in Java, apply the logic to auto adjust everything? Or should that part be in PL/SQL in stored procedure call? This is something that we need for a couple other tables so it'd be nice to abstract. If anyone has something like this already written, please share :) I did find this reference: http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:474221407101 Here's an example of how each of the 4 overlapping cases should be handled for adjustment on insert: = Example 1 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (20, 50, 'A') Gives (0, 10, 'X') **(20, 50, 'A') **(51, 100, 'Z') (200, 500, 'Y') = Example 2 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (40, 80, 'A') Gives (0, 10, 'X') **(30, 39, 'Z') **(40, 80, 'A') **(81, 100, 'Z') (200, 500, 'Y') = Example 3 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (50, 120, 'A') Gives (0, 10, 'X') **(30, 49, 'Z') **(50, 120, 'A') (200, 500, 'Y') = Example 4 = In DB (Start, End, Value): (0, 10, 'X') **(30, 100, 'Z') (200, 500, 'Y') Input (20, 120, 'A') Gives (0, 10, 'X') **(20, 120, 'A') (200, 500, 'Y') The algorithm is as follows: given range = g; input range = i; output range set = o if i.start <= g.start if i.end >= g.end o_1 = i else o_1 = i o_2 = (o.end + 1, g.end) else if i.end >= g.end o_1 = (g.start, i.start - 1) o_2 = i else o_1 = (g.start, i.start - 1) o_2 = i o_3 = (i.end + 1, i.end)

  • Custom template for Django's comments application does not display fields

    - by Jannis
    Hi, I want to use django.contrib.comments in a blogging application and customize the way the form is displayed. My problem is that I can't get the fields to display although displaying the hidden fields works just fine. I had a look at the docs and compared it with the regular way of displaying forms but honestly I don't know why the following doesn't work out: {% get_comment_form for comments_object as form %} <form action="{% comment_form_target %}" method="POST"> […] {% for hidden in form.hidden_fields %} {{ hidden }} {% endfor %} {% for field in form.fields %} {{field}} {% endfor %} […] </form> The output looks like this: <form action="/comments/post/" method="POST"> <input type="hidden" name="content_type" value="flatpages.flatpage" id="id_content_type" /> <input type="hidden" name="object_pk" value="1" id="id_object_pk" /> <input type="hidden" name="timestamp" value="1269522506" id="id_timestamp" /> <input type="hidden" name="security_hash" value="ec4…0fd" id="id_security_hash" /> content_type object_pk timestamp security_hash name email url comment honeypot […] </form> </div> Can you tell me what I'm doing wrong?

  • Getting "Comment post not allowed (400)" when using Django Comments

    - by kfordham281
    I'm going through a Django book and I seem to be stuck. The code base used in the book is .96 and I'm using 1.0 for my Django install. The portion I'm stuck at is related to Django comments (django.contrib.comments). When I submit my comments I get "Comment post not allowed (400) Why: Missing content_type or object_pk field". I've found the Django documentation to be a bit lacking in this area and I'm hoping to get some help. The comment box is displayed just fine, it's when I submit the comment that I get the above error (or security warning as it truly appears). My call to the comment form: {% render_comment_form for bookmarks.sharedbookmark shared_bookmark.id %} My form.html code: {% if user.is_authenticated %} <form action="/comments/post/" method="post"> <p><label>Post a comment:</label><br /> <textarea name="comment" rows="10" cols="60"></textarea></p> <input type="hidden" name="options" value="{{ options }}" /> <input type="hidden" name="target" value="{{ target }}" /> <input type="hidden" name="gonzo" value="{{ hash }}" /> <input type="submit" name="post" value="submit comment" /> </form> {% else %} <p>Please <a href="/login/">log in</a> to post comments.</p> {% endif %} Any help would be much appreciated. My view as requested: def bookmark_page(request, bookmark_id): shared_bookmark = get_object_or_404( SharedBookmark, id=bookmark_id ) variables = RequestContext(request, { 'shared_bookmark': shared_bookmark }) return render_to_response('bookmark_page.html', variables)

  • javascript function won't stop looping - It's on a netsuite website

    - by Lauren
    I need to change the shipping carrier drop-down and shipping method radio button once via a javascript function, not forever. However, when I use this function, which executes when on the Review and Submit page when the order is < $5, it goes into an endless loop: function setFreeSampShipping(){ var options = document.forms['checkout'].shippingcarrierselect.getElementsByTagName('option'); for (i=0;i<options.length;i++){ if (options[i].value == 'nonups'){ document.forms['checkout'].shippingcarrierselect.value='nonups'; document.forms['checkout'].shippingcarrierselect.onchange(); document.location.href='/app/site/backend/setshipmeth.nl?c=659197&n=1&sc=4&sShipMeth=2035'; } } } It gets called from within this part of the function setSampPolicyElems() which you can see I've commented out to stop the loop: if (carTotl < 5 && hasSampp == 1) { /* if (document.forms['checkout'].shippingcarrierselect.value =='ups'){ setFreeSampShipping(); } */ document.getElementById('sampAdd').style.display="none"; document.getElementById("custbody_ava_webshiptype").value = "7";//no charge free freight if (document.getElementById("applycoupon")) { document.location.href='/app/site/backend/setpromocode.nl?c=659197&n=1&sc=4&kReferralCode=SAMPLE' } document.write("<div id='msg'><strong>Sample & Shipping:</strong></span> No Charge.

  • Default values for Content Taxonomy fields in Drupal with Hierarchical Select widget

    - by lazysoundsystem
    I'm trying to set the default value for a Content Taxonomy field in a hook_form_alter, but can't pin down the necessary format. I've tried this and many variations: foreach (element_children($form) as $child) { // Set $default_value. if ($form[$child]['tids']) { // This, for Content Taxonomy fields, isn't working: $form[$child]['tids']['#default_value'] = array('value' => $default_value); dsm($form[$child]['tids']['#default_value']); } else { // This, for other fields, is working: $form[$child][0]['#default_value']['value'] = $default_value; } } Can anyone tell me what I'm missing? Edit: In response to Henrik Opel (thanks for getting involved), here is the print out of the relevant field of the form with my changes to the default fields commented out, showing the '#default_value' field I'm trying to influence. It also shows that the option widget I'm using is Hierarchical Select (could this be a factor?). In the dsm() in the code above, the changes to the default value are recognised, but they don't get processed later on. field_name_of_content_taxonomy_field (Array, 3 elements) #tree (Boolean) TRUE #weight (String, 1 characters ) 5 tids (Array, 7 elements) #title (String, 10 characters ) Vocabulary_name #type (String, 19 characters ) hierarchical_select #weight (String, 1 characters ) 5 #config (Array, 15 elements) // 15 elements here #required (String, 1 characters ) 0 #description (String, 0 characters ) #default_value (Array, 0 elements)

  • Custom model validation of dependent properties using Data Annotations

    - by Darin Dimitrov
    Since now I've used the excellent FluentValidation library to validate my model classes. In web applications I use it in conjunction with the jquery.validate plugin to perform client side validation as well. One drawback is that much of the validation logic is repeated on the client side and is no longer centralized at a single place. For this reason I'm looking for an alternative. There are many examples out there showing the usage of data annotations to perform model validation. It looks very promising. One thing I couldn't find out is how to validate a property that depends on another property value. Let's take for example the following model: public class Event { [Required] public DateTime? StartDate { get; set; } [Required] public DateTime? EndDate { get; set; } } I would like to ensure that EndDate is greater than StartDate. I could write a custom validation attribute extending ValidationAttribute in order to perform custom validation logic. Unfortunately I couldn't find a way to obtain the model instance: public class CustomValidationAttribute : ValidationAttribute { public override bool IsValid(object value) { // value represents the property value on which this attribute is applied // but how to obtain the object instance to which this property belongs? return true; } } I found that the CustomValidationAttribute seems to do the job because it has this ValidationContext property that contains the object instance being validated. Unfortunately this attribute has been added only in .NET 4.0. So my question is: can I achieve the same functionality in .NET 3.5 SP1? UPDATE: It seems that FluentValidation already supports clientside validation and metadata in ASP.NET MVC 2. Still it would be good to know though if data annotations could be used to validate dependent properties.

  • Conditionally display row using JSF Datatable

    - by Elie
    I have some JSF code that currently works (as shown below), and I need to modify it to conditionally suppress the display of certain rows of the table. I know how to conditionally suppress the display of a particular cell, but that seems to create an empty cell, while what I'm trying to do is to not display the row at all. Any suggestions? <h:dataTable styleClass="resultsTable" id="t1" value="#{r.common}" var="com" headerClass="headerBackgrnd" rowClasses="rowOdd, rowEven" columnClasses="leftAlign, rightAlign, leftAlign"> <h:column> <h:outputText rendered="#{com.rendered}" styleClass="inputText" value="#{com.description}: " /> </h:column> <h:column> <h:outputText styleClass="outputText" value="#{com.v1}" /> </h:column> <h:column> <h:inputText styleClass="inputText" value="#{com.v2}" /> </h:column> </h:dataTable> Basically, the line that says #{com.rendered} will conditionally display the contents of a single cell, producing an empty cell when com.rendered is false. But I want to skip an entire row of the display under certain conditions - how would I go about doing that?

  • Dojo: dojo onblur events

    - by Jane Wilkie
    Hi guys, I have a form setup with dojo 1.5. I am using a dijit.form.ComboBox and a dijit.form.TextBox The Combobox has values like "car","bike","motorcycle" and the textbox is meant to be an adjective to the Combobox. So it doesn't matter what is in the Combobox but if the ComboBox does have a value then something MUST be filled in the TextBox. Optionally, if nothing is in the ComboBox, then nothing can be in the TextBox and that is just fine. In fact if something isn't in the Combobox then nothing MUST be in the text box. In regular coding I would just use an onBlur event on the text box to go to a function that checks to see if the ComboBox has a value. I see in dojo that this doesn't work... Code example is below... Vehicle: <input dojoType="dijit.form.ComboBox" store="xvarStore" value="" searchAttr="name" name="vehicle_1" id="vehicle_1" /> Descriptor: <input type="text" dojoType="dijit.form.TextBox" value="" class=lighttext style="width:350px;height:19px" id="filter_value_1" name="filter_value_1" /> My initial attempt was to add an onBlur within the Descriptor's <input> tag but discovered that that doesn't work. How does Dojo handle this? Is it via a dojo.connect parameter? Even though in the example above the combobox has an id of "vehicle_1" and the text box has an id of "filter_value_1", there can be numerous comboboxes and textboxes numbering sequentially upward. (vehicle_2, vehicle_3, etc) Any advice or links to resources would be greatly appreciated. Janie

  • Deserialize generic collections - coming up empty

    - by AC
    I've got a settings object for my app that has two collections in it. The collections are simple List generics that contain a collection of property bags. When I serialize it, everything is saved with no problem: XmlSerializer x = new XmlSerializer(settings.GetType()); TextWriter tw = new StreamWriter(@"c:\temp\settings.cpt"); x.Serialize(tw, settings); However when I deserialize it, everything is restored except for the two collections (verified by setting a breakpoint on the setters: XmlSerializer x = new XmlSerializer(typeof(CourseSettings)); XmlReader tr = XmlReader.Create(@"c:\temp\settings.cpt"); this.DataContext = (CourseSettings)x.Deserialize(tr); What would cause this? Everything is pretty vanilla... here's a snippet from the settings object... omitting most of it. The PresentationSourceDirectory works just fine, but the PresentationModules' setter isn't hit: private string _presentationSourceDirectory = string.Empty; public string PresentationSourceDirectory { get { return _presentationSourceDirectory; } set { if (_presentationSourceDirectory != value) { OnPropertyChanged("PresentationSourceDirectory"); _presentationSourceDirectory = value; } } } private List<Module> _presentationModules = new List<Module>(); public List<Module> PresentationModules { get { var sortedModules = from m in _presentationModules orderby m.ModuleOrder select m; return sortedModules.ToList<Module>(); } set { if (_presentationModules != value) { _presentationModules = value; OnPropertyChanged("PresentationModules"); } } }

  • inbound/outbound url routing in asp.net MVC

    - by Stephane
    The routing I need is quite simple, I must be missing something there. As code example I put the simpler situation where I can reproduce my behavior. You have this ActionMethod : public ActionResult Index(string provider) { ViewData["Message"] = provider; return View("Index"); } And you have this route : routes.MapRoute( null, "{controller}/{action}/{provider}", new { controller = "Home", action = "Index", provider = "Default" } ); // Parameter defaults You can call /Home/Index/Custom and provider will take the value "Custom" What Route would I need if I want the url /?provider=Custom to map the provider to the parameter. I thought that would just work, because the default controller and the default action would be used, and the provider from the querystring would be used instead of the default one. but the querystring is just ignored here. That's a problem in my situation as I have a form using HTTP GET method. The form action has to be Html.BeginForm(c=c.Index(null)) which is resolved as / and the value of my form are added in the querystring. (the provider being a dropdown in the form) So the url built by the form is /?abc=value&cde=value...

  • ComboBox exception caused in winforms FormClosing event

    - by Spooky2010
    Using c# vs2008 winforms I have an application with a bunch of child winforms. Each time a form is closed I need to store the current selected value of a combobox that is on each form to a Global application variable so that I can track it and use it in new forms. The combobox is populated on form start via a method to set its datasource to an ArrayList of items What I have found is if the combobox is populated with items in the designer, and you try to get the combobox value in the form closing event, I always get a NullReferenceException. However if the comboBox has an datasource like I DO have in my application and I try to get the combobox value in the form closing event then I would say 95% of the time I DO NOT get the NullReferenceException, but I do get it 5% of the time. That ratio can even vary depending on what computer I run the application on. for example I have 1 computer where the exception always occurs. My question is therefore what is (the best) way to get the value of the combobox, last thing before the form closes without causing the exception. I would def prefer to do it last thing before the form closes rather than track it with every selected index change event. Any advice appreciated.

  • Problem using Hibernate Projections

    - by Lucas
    Hello! I'm using Richfaces + HibernateQuery to create a data list. I'm trying to use Hibernate Projections to group my query result. Here is the code: final DetachedCriteria criteria = DetachedCriteria .forClass(Class.class, "c") .setProjection(Projections.projectionList() .add(Projections.groupProperty("c.id"))); ... in the .xhtml file i have the following code: <rich:dataTable width="100%" id="dataTable" value="#{myBean.dataModel}" var="row"> <f:facet name="header"> <rich:columnGroup> ...... </rich:columnGroup> </f:facet> <h:column> <h:outputText value="#{row.id}"/> </h:column> <h:column> <h:outputText value="#{row.name}"/> </h:column> But when i run the page it gives me the following error: Error: value="#{row.id}": The class 'java.lang.Long' does not have the property 'id'. If i take out the Projection from the code it works correctly, but it doesn't group the result. So, which mistake could be happening here? EDIT: Here is the full criteria: final DetachedCriteria criteria = DetachedCriteria.forClass(Class.class, "c"); criteria.setFetchMode("e.zzzzz", FetchMode.JOIN); criteria.createAlias("e.aaaaaaaa", "aa"); criteria.add(Restrictions.ilike("aa.information", "informations....")); criteria.setProjection(Projections.distinct(Projections.projectionList() .add(Projections.groupProperty("e.id").as("e.id")))); getDao().findByCriteria(criteria); if i take the "setProjection" line it works fine. I don't understand why it gives that error putting that line.

  • How to marshall non-string objects with JAXB and Spring

    - by lesula
    I was trying to follow this tutorial in order to create my own restful web-service using Spring framework. The client do a GET request to, let's say http://api.myapp/app/students and the server returns an xml version of the object classroom: @XmlRootElement(name = "class") public class Classroom { private String classId = null; private ArrayList<Student> students = null; public Classroom() { } public String getClassId() { return classId; } public void setClassId(String classId) { this.classId = classId; } @XmlElement(name="student") public ArrayList<Student> getStudents() { return students; } public void setStudents(ArrayList<Student> students) { this.students = students; } } The object Student is another bean containing only Strings. In my app-servlet.xml i copied this lines: <bean id="studentsView" class="org.springframework.web.servlet.view.xml.MarshallingView"> <constructor-arg ref="jaxbMarshaller" /> </bean> <!-- JAXB2 marshaller. Automagically turns beans into xml --> <bean id="jaxbMarshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller"> <property name="classesToBeBound"> <list> <value>com.spring.datasource.Classroom</value> <value>com.spring.datasource.Student</value> </list> </property> </bean> Now my question is: what if i wanted to insert some non-string objects as class variables? Let's say i want a tag containing the String version of an InetAddress, such as <inetAddress>192.168.1.1</inetAddress> How can i force JAXB to call the method inetAddress.toString() in such a way that it appears as a String in the xml? In the returned xml non-string objects are ignored!

  • Need help with creating complex UITableView items (like the Settings app).

    - by Craig
    I hoping to create a custom Settings view, similar to the Settings application, but with more control over the UI and access to some settings (i need to lock some of the settings). Obvously, there are a variety of UI elements mixed in each row of application's UITableView. For example, the 'Airplane Mode' setting shows a UISwitch, while the 'Wi-Fi' setting has a text value adjacent to the disclosure symbol (''). Further complicating matters, is the grouping of these settings. I have some general questions about the approach I should take: Seems like i need to save the name of the setting, its current value, its grouping, and the type of UI element(s) needed to modify its value. i would like to make use [NSUserDefault standardUserDefaults], but not have these settings appear in the Settings application. I'm guessing that I will need to create my own settings-persistence class. is it better to build each one of these complex UI-element combinations in code or to create a series of custom views based on the UITableViewCell and load the appropriate one? i'm guessing the latter. some of the setting require that i load another view to select its value. assuming that the application is based on the Utility pattern, should the SettingsView manage the navigation stack, rather than having the app delegate do so? Thanks for your time and comments. Craig Buchanan

  • boost::binding that which is already bound

    - by PaulH
    I have a Visual Studio 2008 C++ application that does something like this: template< typename Fcn > inline void Bar( Fcn fcn ) // line 84 { fcn(); }; template< typename Fcn > inline void Foo( Fcn fcn ) { // this works fine Bar( fcn ); // this fails to compile boost::bind( Bar, fcn )(); }; void main() { SYSTEM_POWER_STATUS_EX status = { 0 }; Foo( boost::bind( ::GetSystemPowerStatusEx, &status, true ) ); // line 160 } *The call to GetSystemPowerStatusEx() is just for demonstration. Insert your favorite call there and the behavior is the same. When I go to compile this, I get 84 errors. I won't post them all unless asked, but they start with this: 1>.\MyApp.cpp(99) : error C2896: 'boost::_bi::bind_t<_bi::dm_result<MT::* ,A1>::type,boost::_mfi::dm<M,T>,_bi::list_av_1<A1>::type> boost::bind(M T::* ,A1)' : cannot use function template 'void Bar(Fcn)' as a function argument 1> .\MyApp.cpp(84) : see declaration of 'Bar' 1> .\MyApp.cpp(160) : see reference to function template instantiation 'void Foo<boost::_bi::bind_t<R,F,L>>(Fcn)' being compiled 1> with 1> [ 1> R=BOOL, 1> F=BOOL (__cdecl *)(PSYSTEM_POWER_STATUS_EX,BOOL), 1> L=boost::_bi::list2<boost::_bi::value<_SYSTEM_POWER_STATUS_EX *>,boost::_bi::value<bool>>, 1> Fcn=boost::_bi::bind_t<BOOL,BOOL (__cdecl *)(PSYSTEM_POWER_STATUS_EX,BOOL),boost::_bi::list2<boost::_bi::value<_SYSTEM_POWER_STATUS_EX *>,boost::_bi::value<bool>>> 1> ] If anybody can point out what I may be doing wrong, I would appreciate it.

  • Formula parsing / evaluation routine or library with generic DLookup functionality

    - by tbone
    I am writing a .Net application where I must support user-defined formulas that can perform basic mathematics, as well as accessing data from any arbitrary table in the database. I have the math part working, using JScript Eval(). What I haven't decided on is what a nice way is to do the generic table lookups. For example, I may have a formula something like: Column: BonusAmount Formula: {CurrentSalary} * 1.5 * {[SystemSettings][Value][SettingName=CorpBonus AND Year={Year}]} So, in this example I would replace {xxx} and {Year} with the value of Column xxx from the current table, and I would replace the second part with the value of (select Value from SystemSettings WHERE SettingName='CorpBonus' AND Year=2008) So, basically, I am looking for something very much like the MS Access DLookup function: DLookup ( expression, domain, [criteria] ) DLookup("[UnitPrice]", "Order Details", "OrderID = 10248") But, I also need to overall parsing routine that can tell whether to just look up in the current row, or to look into another table. Would also be nice to support aggregate functions (ie: DAvg, DMax, etc), as well as all the weird edge cases handled. So I wonder if anyone knows of any sort of an existing library, or has a nice routine that can handle this formula parsing and database lookup / aggregate function resolution requirements.

  • How do I handle a POST request in Perl and FastCGI?

    - by Peterim
    Unfortunately, I'm not familiar with Perl, so asking here. Actually I'm using FCGI with Perl. I need to 1. accept a POST request - 2. send it via POST to another url - 3. get results - 4. return results to the first POST request (4 steps). To accept a POST request (step 1) I use the following code (found it somewhere in the Internet): $ENV{'REQUEST_METHOD'} =~ tr/a-z/A-Z/; if ($ENV{'REQUEST_METHOD'} eq "POST") { read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'}); } else { print ("some error"); } @pairs = split(/&/, $buffer); foreach $pair (@pairs) { ($name, $value) = split(/=/, $pair); $value =~ tr/+/ /; $value =~ s/%(..)/pack("C", hex($1))/eg; $FORM{$name} = $value; } The content of $name (it's a string) is the result of the first step. Now I need to send $name via POST request to some_url (step 2) which returns me another result (step 3), which I have to return as a result to the very first POST request (step 4). Any help with this would be greatly appreciated. Thank you.
