  • FusionCharts Sharepoint And dataUrl param.

    - by oivoodoo
    Hi, everyone. I have problem with fusioncharts evaluation in the ASP .NET(Sharepoint Portal). I am customizing survey list for providing new view. I added to scheme.xml the next code. <View BaseViewID="4" Type="HTML" WebPartZoneID="Main" DefaultView="TRUE" DisplayName="Charts" SetupPath="pages\viewpage.aspx" ImageUrl="/_layouts/images/survey.png" Url="overview.aspx" FreeForm="TRUE" ReadOnly="TRUE"> <!-- _locID@DisplayName="camlidV1" _locComment=" " --> <Toolbar Type="Standard" /> <ViewFields> </ViewFields> <ViewEmpty> <SetVar Name="HandlerUrl">/_layouts/IEFS/SurveyHandler.aspx</SetVar> <HTML> <![CDATA[ <!-- START Code Block for Chart 'ChartName' --> <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0" width="350" height="350" name="SurveyChart"> <param name="allowScriptAccess" value="always" /> <param name="movie" value="/_layouts/IEFS/FusionCharts/MSCombi3D.swf"/> <param name="FlashVars" value="&chartWidth=350&chartHeight=350&debugMode=1&dataURL=]]> </HTML> <GetVar Name="HandlerUrl" /> <HTML> <![CDATA["/>]]> </HTML> <HTML> <![CDATA[ <param name="quality" value="high" /> <embed src="/_layouts/IEFS/FusionCharts/MSCombi3D.swf" FlashVars="&chartWidth=350&chartHeight=350&debugMode=1&dataURL=]]> </HTML> <GetVar Name="HandlerUrl" /> <HTML> <![CDATA[" quality="high" width="350" height="350" name="ChartName" allowScriptAccess="always" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /> </object> <!-- END Code Block for Chart 'ChartName' --> ]]> </HTML> </ViewEmpty> As you can see I've just create standard object tag of fusioncharts control(I got it from examples). But when page is rendered I can see the next following error: And I have error: INFO: XML Data provided using dataURL method. dataURL provided: ./_layouts/IEFS/SurveyHandler.aspx dataURL invoked: ./_layouts/IEFS/SurveyHandler.aspx?FCTime=223 ERROR: An error occurred while loading data. Please check your dataURL, by clicking on the "dataURL invoked" link above, to see if it's returing valid XML data. Common causes for error are: No URL Encoding provided for querystrings in dataURL. If your dataURL contains querystrings as parameters, you'll need to URL Encode the same. e.g., Data.asp?id=101&subId=242 should be Data%2Easp%3Fid%3D101%26subId%3D242 Different sub-domain of chart .swf and dataURL. Both need to be same owing to sandbox security. Network error My data-page(handler) is rendered valid xml data. I read this link http://www.fusioncharts.com/docs?/Debug/Basic.html, but it doesn't help me. Have ever you seen same error before? With The Best Regards, Alexander.

  • WiX Action Sequence

    - by Damian Vogel
    I was looking for list of actions and their sequence when running a WiX setup. Somehow the official website doesn't seem to provide any information. The basic problem is that I want to schedule my custom actions correctly. Typically I need to register a DLL with regsvr32.exe, and this can only be done once the files are copied to the harddrive. However the custom action <Custom Action="RegisterShellExt" After="InstallFiles"> failed with the error message "file not found". What I've done then is analizing the log of my MSI with WiX Edit, and I've found that the Action InstallFiles exists more than once. And effectively the files are written only the second time it appears. So I changed my custom action to the following : <Custom Action="RegisterShellExt" Before="InstallFinalize"> Here is the sequence I've extracted from the logs of my MSI: Action start 15:16:49: INSTALL. Action start 15:16:49: PrepareDlg. Action start 15:16:49: AppSearch. Action start 15:16:49: LaunchConditions. Action start 15:16:49: ValidateProductID.

  • Struts2 Populating Checkbox from Arraylist of Objects

    - by user2972139
    I'm sure that I'm doing something dumb but I've been going craze over the last couple of days trying to get my checkboxes filled out inside an iterator that goes over an arraylist of object. Here is my object: public class EmailObject { int emailId; String emailAddress; public int getEmailId() { return emailId; } public void setEmailId(int emailId) { this.emailId = emailId; } public String getEmailAddress() { return emailAddress; } public void setEmailAddress(String emailAddress) { this.emailAddress = emailAddress; } } In my action class, I create an arraylist of the above EmailObjects. On my jsp page, I can get checkboxes through a checkboxlist (but this isn't good for me because I want it to be vertical and don't want to mess with the struts styles) <s:checkboxlist name="selectedEmails" list="userEmails" listValue="emailAddress" listKey="emailId" /> I can also iterate over the arraylist userEmails and display the values: <s:iterator value="userEmails" var="thisEmailData"> <s:property value="emailId"/> <s:property value="emailAddress"/> </s:iterator> But I can't get it to display the emailId when iterating over the arraylist userEmails. I tried all of these: <s:iterator value="userEmails" var="thisEmailData"> <tr><td><s:property value="emailId"/></td></tr> <tr><td> <s:checkbox fieldValue="%{#emailId}" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox fieldValue="#emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox fieldValue="thisEmailData.emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox fieldValue="userEmails.emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox fieldValue="#thisEmailData.emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox fieldValue="#userEmails.emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox fieldValue="%{#thisEmailData.emailId}" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox fieldValue="%{#userEmails.emailId}" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox fieldValue="emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="%{#emailId}" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="#emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="thisEmailData.emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="userEmails.emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="#thisEmailData.emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="#userEmails.emailId" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="%{#thisEmailData.emailId}" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="%{#userEmails.emailId}" name="emailAddressesCB" theme="simple" ></s:checkbox> <s:checkbox value="emailId" name="emailAddressesCB" theme="simple" > </s:checkbox> <s:property value="emailAddress"/> </td></tr> </s:iterator> </td></tr> </s:iterator> From the above, the value field is never filled with the value of the emailId. I know I'm missing something basic. What is it? THANK YOU.

  • How do you automap List<float> or float[] with Fluent NHibernate?

    - by Tom Bushell
    Having successfully gotten a sample program working, I'm now starting to do Real Work with Fluent NHibernate - trying to use Automapping on my project's class heirarchy. It's a scientific instrumentation application, and the classes I'm mapping have several properties that are arrays of floats e.g. private float[] _rawY; public virtual float[] RawY { get { return _rawY; } set { _rawY = value; } } These arrays can contain a maximum of 500 values. I didn't expect Automapping to work on arrays, but tried it anyway, with some success at first. Each array was auto mapped to a BLOB (using SQLite), which seemed like a viable solution. The first problem came when I tried to call SaveOrUpdate on the objects containing the arrays - I got "No persister for float[]" exceptions. So my next thought was to convert all my arrays into ILists e.g. public virtual IList<float> RawY { get; set; } But now I get: NHibernate.MappingException: Association references unmapped class: System.Single Since Automapping can deal with lists of complex objects, it never occured to me it would not be able to map lists of basic types. But after doing some Googling for a solution, this seems to be the case. Some people seem to have solved the problem, but the sample code I saw requires more knowledge of NHibernate than I have right now - I didn't understand it. Questions: 1. How can I make this work with Automapping? 2. Also, is it better to use arrays or lists for this application? I can modify my app to use either if necessary (though I prefer lists). Edit: I've studied the code in Mapping Collection of Strings, and I see there is test code in the source that sets up an IList of strings, e.g. public virtual IList<string> ListOfSimpleChildren { get; set; } [Test] public void CanSetAsElement() { new MappingTester<OneToManyTarget>() .ForMapping(m => m.HasMany(x => x.ListOfSimpleChildren).Element("columnName")) .Element("class/bag/element").Exists(); } so this must be possible using pure Automapping, but I've had zero luck getting anything to work, probably because I don't have the requisite knowlege of manually mapping with NHibernate. Starting to think I'm going to have to hack this (by encoding the array of floats as a single string, or creating a class that contains a single float which I then aggregate into my lists), unless someone can tell me how to do it properly. End Edit Here's my CreateSessionFactory method, if that helps formulate a reply... private static ISessionFactory CreateSessionFactory() { ISessionFactory sessionFactory = null; const string autoMapExportDir = "AutoMapExport"; if( !Directory.Exists(autoMapExportDir) ) Directory.CreateDirectory(autoMapExportDir); try { var autoPersistenceModel = AutoMap.AssemblyOf<DlsAppOverlordExportRunData>() .Where(t => t.Namespace == "DlsAppAutomapped") .Conventions.Add( DefaultCascade.All() ) ; sessionFactory = Fluently.Configure() .Database(SQLiteConfiguration.Standard .UsingFile(DbFile) .ShowSql() ) .Mappings(m => m.AutoMappings.Add(autoPersistenceModel) .ExportTo(autoMapExportDir) ) .ExposeConfiguration(BuildSchema) .BuildSessionFactory() ; } catch (Exception e) { Debug.WriteLine(e); } return sessionFactory; }

  • Converting listview to a composite control

    - by Paul
    The link below shows a listview composite control in its most basic form however I can't seem to extend this to what I'm trying to do. http://stackoverflow.com/questions/92689/how-to-define-listview-templates-in-code My listview has 1 tablerow with 2 fields. The first field contains 1 element whilst the second field contains 2 elements as shown below. <asp:ListView ID="lstArticle" runat="server"> <LayoutTemplate> <table id="itemPlaceholder" runat="server"> </table> </LayoutTemplate> <ItemTemplate> <div class="ctrlArticleList_rptStandardItem"> <table width="100%"> <tr> <td valign="top" class="ctrlArticleList_firstColumnWidth"> <a href="<%# GetURL(Container.DataItem) %>"> <%# GetImage(Container.DataItem)%> </a> </td> <td valign="top"> <span class="ctrlArticleList_title"> <a href="<%# GetURL(Container.DataItem) %>"> <%# DataBinder.Eval(Container.DataItem, "Title") %> </a> </span> <span class="ctrlArticleList_date"> <%# convertToShortDate(DataBinder.Eval(Container.DataItem, "ActiveDate"))%> </span> <div class="ctrlArticleList_standFirst"> <%# DataBinder.Eval(Container.DataItem, "StandFirst")%> </div> </td> </tr> </table> </div> </ItemTemplate> So to convert this I have to use the InstantiateIn method of the ITemplate for the layouttemplate and the ItemTemplate. Data is bound to the itemtemplate using the DataBinding event. My question at the moment is how do I setup the ItemTemplate class and bind the values from the above ListView ItemTemplate. This is what I've managed so far: private class LayoutTemplate : ITemplate { public void InstantiateIn(Control container) { var table = new HtmlGenericControl("table") { ID = "itemPlaceholder" }; container.Controls.Add(table); } } private class ItemTemplate : ITemplate { public void InstantiateIn(Control container) { var tableRow = new HtmlGenericControl("tr"); //first field in row var tableFieldImage = new HtmlGenericControl("td"); var imageLink = new HtmlGenericControl("a"); imageLink.ID = "imageLink"; tableRow.Controls.Add(imageLink); // second field in row var tableFieldTitle = new HtmlGenericControl("td"); var title = new HtmlGenericControl("a"); tableFieldTitle.Controls.Add(title); tableRow.Controls.Add(tableFieldTitle); //Bind the data with the controls tableRow.DataBinding += BindData; //add the controls to the container container.Controls.Add(tableRow); } public void BindData(object sender, EventArgs e) { var container = (HtmlGenericControl)sender; var dataItem = ((ListViewDataItem)container.NamingContainer).DataItem; container.Controls.Add(new Literal() { Text = dataItem.ToString() }); } One of the functions in the ListView just for an example is: public string GetURL(object objArticle) { ArticleItem articleItem = (ArticleItem)objArticle; Article article = new Article(Guid.Empty, articleItem.ContentVersionID); return GetArticleURL(article); } Summary What do I need to do to convert the following into a composite control: 1. <a href="<%# GetURL(Container.DataItem) %>"><%# GetImage(Container.DataItem)%></a> 2. <a href="<%# GetURL(Container.DataItem) %>"> <%# DataBinder.Eval(Container.DataItem, "Title") %> </a>

  • How do you traverse and store XML in Blackberry Java app?

    - by Greg
    I'm having a problem accessing the contents of an XML document. My goal is this: Take an XML source and parse it into a fair equivalent of an associative array, then store it as a persistable object. the xml is pretty simple: <root> <element> <category_id>1</category_id> <name>Cars</name> </element> <element> <category_id>2</category_id> <name>Boats</name> </element> </root> Basic java class below. I'm pretty much just calling save(xml) after http response above. Yes, the xml is properly formatted. import java.io.IOException; import java.util.Hashtable; import org.w3c.dom.Document; import org.w3c.dom.Node; import org.w3c.dom.NodeList; import java.util.Vector; import net.rim.device.api.system.PersistentObject; import net.rim.device.api.system.PersistentStore; import net.rim.device.api.xml.parsers.DocumentBuilder; import net.rim.device.api.xml.parsers.DocumentBuilderFactory; public class database{ private static PersistentObject storeVenue; static final long key = 0x2ba5f8081f7ef332L; public Hashtable hashtable; public Vector venue_list; String _node,_element; public database() { storeVenue = PersistentStore.getPersistentObject(key); } public void save(Document xml) { venue_list = new Vector(); storeVenue.setContents(venue_list); Hashtable categories = new Hashtable(); try{ DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory. newInstance(); DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); docBuilder.isValidating(); xml.getDocumentElement ().normalize (); NodeList list=xml.getElementsByTagName("*"); _node=new String(); _element = new String(); for (int i=0;i<list.getLength();i++){ Node value=list.item(i).getChildNodes().item(0); _node=list.item(i).getNodeName(); _element=value.getNodeValue(); categories.put(_element, _node); } } catch (Exception e){ System.out.println(e.toString()); } venue_list.addElement(categories); storeVenue.commit(); } The code above is the work in progress, and is most likely heavily flawed. However, I have been at this for days now. I can never seem to get all child nodes, or the name / value pair. When I print out the vector as a string, I usually end up with results like this: [{ = root, = element}] and that's it. No "category_id", no "name" Ideally, I would end up with something like [{1 = cars, 2 = boats}] Any help is appreciated. Thanks

  • php script gets two ajax requests, only returns one?

    - by Dan.StackOverflow
    I'll start from the beginning. I'm building a wordpress plugin that does double duty, in that it can be inserted in to a post via a shortcode, or added as a sidebar widget. All it does is output some js to make jquery.post requests to a local php file. The local php file makes a request to a webservice for some data. (I had to do it this way instead of directly querying the web service with jquery.ajax because the url contains a license key that would be public if put in the js). Anyway, When I am viewing a page in the wordpress blog that has both the sidebar widget and the plugin output via shortcode only one of the requests work. I mean it works in that it gets a response back from the php script. Once the page is loaded they both work normally when manually told to. Webpage view - send 2 post requests to my php script - both elements should be filed in, but only one is. My php script is just: <?php if(isset($_POST["zip"])) { // build a curl object, execute the request, // and basically just echo what the curl request returns. } ?> Pretty basic. here is some js some people wanted to see: function widget_getActivities( zip ){ jQuery("#widget_active_list").text(""); jQuery.post("http://localhost/wordpress/wp-content/ActiveAjax.php", { zip: zip}, function(text) { jQuery(text).find("asset").each(function(j, aval){ var html = ""; html += "<a href='" + jQuery(aval).find("trackback").text() + "' target='new'> " + jQuery(aval).find("assetName").text() + "</a><b> at </b>"; jQuery("location", aval).each(function(i, val){ html += jQuery("locationName", val).text() + " <b> on </b>"; }); jQuery("date", aval).each(function(){ html += jQuery("startDate", aval).text(); <!--jQuery("#widget_active_list").append("<div id='ActivityEntry'>" + html + " </div>");--> jQuery("#widget_active_list") .append(jQuery("<div>") .addClass("widget_ActivityEntry") .html(html) .bind("mouseenter", function(){ jQuery(this).animate({ fontSize: "20px", lineHeight: "1.2em" }, 50); }) .bind("mouseleave", function(){ jQuery(this).animate({ fontSize: "10px", lineHeight: "1.2em" }, 50); }) ); }); }); }); } Now imagine there is another function identical to this one except everything that is prepended with 'widget_' isn't prepended. These two functions get called separately via: jQuery(document).ready(function(){ w_zip = jQuery("#widget_zip").val(); widget_getActivities( w_zip ); jQuery("#widget_updateZipLink").click(function() { //start function when any update link is clicked widget_c_zip = jQuery("#widget_zip").val(); if (undefined == widget_c_zip || widget_c_zip == "" || widget_c_zip.length != 5) jQuery("#widget_zipError").text("Bad zip code"); else widget_getActivities( widget_c_zip ); }); }) I can see in my apache logs that both requests are being made. I'm guessing it is some sort of race condition but that doesn't make ANY sense. I'm new to all this, any ideas? EDIT: I've come up with a sub-optimal solution. I have my widget detect if the plugin is also being used on the page, and if so it waits for 3 seconds before performing the request. But I have a feeling this same thing is going to happen if multiple clients perform a page request at the same time that triggers one of the requests to my php script, because I believe the problem is in the php script, which is scary.

  • Manipulating matrix operations (transpose, negation, addition, and mutiplication) using functions in

    - by user292489
    I was trying to manipulate matrices in my input file using functions. My input file is: A 3 3 1 2 3 4 5 6 7 8 9 B 3 3 1 0 0 0 1 0 0 0 1 C 2 3 3 5 8 -1 -2 -3 D 3 5 0 0 0 1 0 1 0 1 0 1 0 1 0 0 1 E 1 1 10 F 3 10 1 0 2 0 3 0 4 0 5 0 0 2 3 -1 -3 -4 -3 8 3 7 0 0 0 4 6 5 8 2 -1 10 I am having trouble in implementing the functions that I declared. I assumed my program will perform those operations: transpose, negate, add, and multiply matices according to the users choice: /* once this program is compiled and executed, it will perform the basic matrix * operations: negation, transpose, addition, and multiplication. */ #include <stdio.h> #include <stdlib.h> #define MAX 10 int readmatrix(FILE *input, char martixname[6],int , mat[10][10], int i, int j); void printmatrix(char matrixname[6], int mat[10][10], int i, int j); void Negate(char matrixname[6], int mat[10][10], int i, int j); void add(char matrixname[6], int mat[10][10],int i, int k); void multiply(char matrixname[], int mat[][10], char A[], int i, int k); void transpose (char matrixname[], int mat[][10], char A[], int); void printT(int mat[][10], int); int selctoption(); char selectmatrix(); int main(int argc, char *argv[]) { char matrixtype[6]; int mat[][10]; FILE *filein; int size; int optionop; int matrixop; int option; if (argc != 2) { printf("Usage: executable input.\n"); exit(0); } filein = fopen(argv[1], "r"); if (!filein) { printf("ERROR: input file not found.\n"); exit (0); } size = readmatrix (filein, matrixtype); printmatrix(matrix[][10], size); option = selectoption(); matrixtype = selectmatrix(); //printf("You have: %5.2f ", deposit); optionop = readmatrix(option, matrix[][10], size); if (choiceop == 6) { printf("Thanks for using the matrix operation program.\n"); exit(0); } printf("Please select from the following matrix operations:\n") printf("\t1. Print matrix\n"); printf("\t2. Negate matrix\n"); printf("\t3. Transpose matrix\n"); printf("\t4. Add matrices\n"); printf("\t5. Multiply matrices\n"); printf("\t6.

  • A little bit of Ajax goes a long way

    - by Holland
    ..except when you're having problems. My problem is this: I have a hierarchical list of categories stored in a database which I wish to output in a dropdown list. The hierarchy comes into place when the subcategories are to be displayed, which are dependent on a parent id (which equals out to the first seven or so main categories listed). My thoughts are relatively simple: when the user clicks the dynamically allocated list of main categories, they are clicking on an option tag. For each option tag, an id (i.e., the parent) is listed in the value attribute, as well as an argument which is sent to a Javascript function which then uses AJAX to get the data via PHP and sends it to my 'javascript.php' file. The file then does magic, and populates the subcategory list, which is dependent on the main category selected. I believe I have the idea down, it's just that I'm implementing the solution improperly, for some reason. Here's what I have so far: from javascript.php <script type="text/javascript" src=<?=JPATH_BASE.DS.'includes'.DS.'jquery.js';?>> var ajax = { ajax.sendAjaxData = function(method, url, dataTitle, ajaxData) { $.ajax({ type: 'post', url: "C:/wamp/www/patention/components/com_adsmanagar/views/edit/tmpl/javascript.php", data: { 'data' : ajaxData }, success: function(result){ // we have the response alert("Your request was successful." + result); }, error: function(e){ alert('Error: ' + e); } }); } ajax.printSubCategoriesOnClick = function(parent) { alert("hello world!"); ajax.sendAjaxData('post', 'javascript.php', 'data' parent); <?php $categories = $this->formData->getCategories($_POST['data']); ?> ajax.printSubCategories(<?=$categories;?>); } ajax.printSubCategories = function(categories) { var select = document.getElementById("subcategories"); for (var i = 0; i < categories.length; i++) { var opt = document.createElement("option"); opt.text = categories['name']; opt.value = categories['id']; } } } </script> the function used to populate the form data function populateCategories($parent, FormData $formData) { $categories = $formData->getCategories($parent); echo "<pre>"; print_r($categories); echo "</pre>"; foreach($categories as $section => $row){ ?> <option value=<?=$row['id'];?> onclick="ajax.printSubCategoriesOnClick(<?=$row['id']?>)"> <? echo $row['name']; ?> </option> <?php } } The problem is that when I try to do a print_r on my $_POST variable, nothing shows up. I also receive an "undefined index" error (which refers to the key I set for the data type). I'm thinking that for some reason, the data is being sent to my form.php file, or my default.php file which includes both the form.php and javascript.php files via a function. Is there something specific that I'm missing here? Just looking up basic AJAX syntax (via jQuery) hasn't helped out, unfortunately.

  • Reading off a socket until end of line C#?

    - by Omar Kooheji
    I'm trying to write a service that listens to a TCP Socket on a given port until an end of line is recived and then based on the "line" that was received executes a command. I've followed a basic socket programming tutorial for c# and have come up with the following code to listen to a socket: public void StartListening() { _log.Debug("Creating Maing TCP Listen Socket"); _mainSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any, _port); _log.Debug("Binding to local IP Address"); _mainSocket.Bind(ipLocal); _log.DebugFormat("Listening to port {0}",_port); _mainSocket.Listen(10); _log.Debug("Creating Asynchronous callback for client connections"); _mainSocket.BeginAccept(new AsyncCallback(OnClientConnect), null); } public void OnClientConnect(IAsyncResult asyn) { try { _log.Debug("OnClientConnect Creating worker socket"); Socket workerSocket = _mainSocket.EndAccept(asyn); _log.Debug("Adding worker socket to list"); _workerSockets.Add(workerSocket); _log.Debug("Waiting For Data"); WaitForData(workerSocket); _log.DebugFormat("Clients Connected [{0}]", _workerSockets.Count); _mainSocket.BeginAccept(new AsyncCallback(OnClientConnect), null); } catch (ObjectDisposedException) { _log.Error("OnClientConnection: Socket has been closed\n"); } catch (SocketException se) { _log.Error("Socket Exception", se); } } public class SocketPacket { private System.Net.Sockets.Socket _currentSocket; public System.Net.Sockets.Socket CurrentSocket { get { return _currentSocket; } set { _currentSocket = value; } } private byte[] _dataBuffer = new byte[1]; public byte[] DataBuffer { get { return _dataBuffer; } set { _dataBuffer = value; } } } private void WaitForData(Socket workerSocket) { _log.Debug("Entering WaitForData"); try { lock (this) { if (_workerCallback == null) { _log.Debug("Initializing worker callback to OnDataRecieved"); _workerCallback = new AsyncCallback(OnDataRecieved); } } SocketPacket socketPacket = new SocketPacket(); socketPacket.CurrentSocket = workerSocket; workerSocket.BeginReceive(socketPacket.DataBuffer, 0, socketPacket.DataBuffer.Length, SocketFlags.None, _workerCallback, socketPacket); } catch (SocketException se) { _log.Error("Socket Exception", se); } } public void OnDataRecieved(IAsyncResult asyn) { SocketPacket socketData = (SocketPacket)asyn.AsyncState; try { int iRx = socketData.CurrentSocket.EndReceive(asyn); char[] chars = new char[iRx + 1]; _log.DebugFormat("Created Char array to hold incomming data. [{0}]",iRx+1); System.Text.Decoder decoder = System.Text.Encoding.UTF8.GetDecoder(); int charLength = decoder.GetChars(socketData.DataBuffer, 0, iRx, chars, 0); _log.DebugFormat("Read [{0}] characters",charLength); String data = new String(chars); _log.DebugFormat("Read in String \"{0}\"",data); WaitForData(socketData.CurrentSocket); } catch (ObjectDisposedException) { _log.Error("OnDataReceived: Socket has been closed. Removing Socket"); _workerSockets.Remove(socketData.CurrentSocket); } catch (SocketException se) { _log.Error("SocketException:",se); _workerSockets.Remove(socketData.CurrentSocket); } } This I thought was going to be a good basis for what I wanted to do, but the code I have appended the incoming characters to a text box one by one and didn't do anything with it. Which doesn't really work for what I want to do. My main issue is the decoupling of the OnDataReceived method from the Wait for data method. which means I'm having issues building a string (I would use a string builder but I can accept multiple connections so that doesn't really work. Ideally I'd like to look while listening to a socket until I see and end of line character and then call a method with the resulting string as a parameter. What's the best way to go about doing this.

  • Interactive Data Language, IDL: Does anybody care?

    - by Alex
    Anyone use a language called Interactive Data Language, IDL? It is popular with scientists. I think it is a poor language because it is proprietary (every terminal running it has to have an expensive license purchased) and it has minimal support (try searching for IDL, the language, right now on stack) . I am trying to convince my colleagues to stop using it and learn C/C++/Python/Fortran/Java/Ruby. Does anybody know about or even care about IDL enough to have opinions on it? What do you think of it? Should I tell my colleagues to stop wasting their time on it now? How can I convince them? Edit: People are getting the impression that I don't know or use IDL. Also, I said IDL has minimal support which is true in one sense, so I must clarify that the scientific libraries are indeed large. I use IDL all the time, but this is exactly the problem: I am only using IDL because colleagues use it. There is a file format IDL uses, the .sav, which can only be opened in IDL. So I must use IDL to work with this data and transfer the data back to colleagues, but I know I would be more efficient in another language. This is like someone sending you a microsoft word file in an email attachment and if you don't understand how wrong that is then you probably write too many words not enough code and you bought microsoft word. Edit: As an alternative to IDL Python is popular. Here is a list of The Pros of IDL (and the cons) from AstroBetter: Pros of IDL Mature many numerical and astronomical libraries available Wide astronomical user base Numerical aspect well integrated with language itself Many local users with deep experience Faster for small arrays Easier installation Good, unified documentation Standard GUI run/debug tool (IDLDE) Single widget system (no angst about which to choose or learn) SAVE/RESTORE capability Use of keyword arguments as flags more convenient Cons of IDL Narrow applicability, not well suited to general programming Slower for large arrays Array functionality less powerful Table support poor Limited ability to extend using C or Fortran, such extensions hard to distribute and support Expensive, sometimes problem collaborating with others that don’t have or can’t afford licenses. Closed source (only RSI can fix bugs) Very awkward to integrate with IRAF tasks Memory management more awkward Single widget system (useless if working within another framework) Plotting: Awkward support for symbols and math text Many font systems, portability issues (v5.1 alleviates somewhat) not as flexible or as extensible plot windows not intrinsically interactive (e.g., pan & zoom) Pros of Python Very general and powerful programming language, yet easy to learn. Strong, but optional, Object Oriented programming support Very large user and developer community, very extensive and broad library base Very extensible with C, C++, or Fortran, portable distribution mechanisms available Free; non-restrictive license; Open Source Becoming the standard scripting language for astronomy Easy to use with IRAF tasks Basis of STScI application efforts More general array capabilities Faster for large arrays, better support for memory mapping Many books and on-line documentation resources available (for the language and its libraries) Better support for table structures Plotting framework (matplotlib) more extensible and general Better font support and portability (only one way to do it too) Usable within many windowing frameworks (GTK, Tk, WX, Qt…) Standard plotting functionality independent of framework used plots are embeddable within other GUIs more powerful image handling (multiple simultaneous LUTS, optional resampling/rescaling, alpha blending, etc) Support for many widget systems Strong local influence over capabilities being developed for Python Cons of Python More items to install separately Not as well accepted in astronomical community (but support clearly growing) Scientific libraries not as mature: Documentation not as complete, not as unified Not as deep in astronomical libraries and utilities Not all IDL numerical library functions have corresponding functionality in Python Some numeric constructs not quite as consistent with language (or slightly less convenient than IDL) Array indexing convention “backwards” Small array performance slower No standard GUI run/debug tool Support for many widget systems (angst regarding which to choose) Current lack of function equivalent to SAVE/RESTORE in IDL matplotlib does not yet have equivalents for all IDL 2-D plotting capability (e.g., surface plots) Use of keyword arguments used as flags less convenient Plotting: comparatively immature, still much development going on missing some plot type (e.g., surface) 3-d capability requires VTK (though matplotlib has some basic 3-d capability)

  • Web service using Data Dynamics ActiveReports occasionally slows down

    - by Swoop
    My company is running into a problem with a web service that is written in C#/ASP.Net. The service receives an identity key for data in SQL Server and a path to generate and save a PDF report for this data. In most cases, this web service returns results to the calling web pages very quickly, usually within a few seconds max. However, it seems to occasionally hit a significant slowdown. The web application calling the web service will generate a timeout error when this slowdown occurs. We have checked and the PDF does get created and saved to the server, so it looks like the web service eventually finishes executing. It seems to take about 1 to 2 minutes for processing to have completed. The PDF is generated using ActiveReports from Data Dynamics. Wwhen this problem occurs, making a small change to the web service's config file (ie, adding a blank space to a connection string line) seems to restart the web service and everything is perfectly ok for a period of time afterwards. Other web applications that are running on the same web server do not seem to experience this type of behavior, only this particular web service. I have added the code for the web service below. It is basic calls to 3rd party libraries. We are not able to recreate this problem in test. I am wondering what might be causing this issue? [WebMethod] public string Publish(int identity, string transactionType, string directory, string filename) { try { AdpConnection Conn = new AdpConnection(ConfigurationManager.AppSettings["myDBConnString"]); AdpCommand Cmd = new AdpCommand("storedproc_GetData", oConn); AdpParameter Param; Cmd.CommandType = CommandType.StoredProcedure; Param = Cmd.CreateParameter("@Identity", DbType.Int32); Param.Value = identity; Cmd.Parameters.Add(oParam); Conn.Open(); string aResponse = Cmd.ExecuteScalar().ToString(); Conn.Close(); if (transactionType == "typeA") { //Parse response DataSet dsResponse = ParseDataResponse(aResponse); //dsResponse.WriteXml(@ConfigurationManager.AppSettings["DocsDir"] + identity.ToString() + ".xml"); DataDynamics.ActiveReports.ActiveReport3 rpt = new DataDynamics.ActiveReports.ActiveReport3(); rpt.LoadLayout(@ConfigurationManager.AppSettings["myReportPath"] + "TypeA.rpx"); rpt.AddNamedItem("ReportPath", @ConfigurationManager.AppSettings["myReportPath"]); rpt.AddNamedItem("XMLSTRING", FormatXML(dsResponse.GetXml())); DataDynamics.ActiveReports.DataSources.XMLDataSource xmlds = new DataDynamics.ActiveReports.DataSources.XMLDataSource(); xmlds.FileURL = null; xmlds.RecordsetPattern = "//DataPatternA"; xmlds.LoadXML(FormatXML(dsResponse.GetXml())); if (!System.IO.Directory.Exists(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\")) { System.IO.Directory.CreateDirectory(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\"); } string sXML = FormatXML(dsResponse.GetXml()); StreamWriter sw = new StreamWriter(@ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".xml", false); sw.Write(sXML); sw.Close(); rpt.DataSource = xmlds; rpt.Run(true); DataDynamics.ActiveReports.Export.Pdf.PdfExport xPdf = new DataDynamics.ActiveReports.Export.Pdf.PdfExport(); xPdf.Export(rpt.Document, @ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".pdf"); } } catch(Exception ex) { return "Error: " + ex.ToString(); } return @ConfigurationManager.AppSettings["DocsDir"] + directory + @"\" + filename + ".pdf"; }

  • Psychology researcher wants to learn new language

    - by user273347
    I'm currently considering R, matlab, or python, but I'm open to other options. Could you help me pick the best language for my needs? Here are the criteria I have in mind (not in order): Simple to learn. I don't really have a lot of free time, so I'm looking for something that isn't extremely complicated and/or difficult to pick up. I know some C, FWIW. Good for statistics/psychometrics. I do a ton of statistics and psychometrics analysis. A lot of it is basic stuff that I can do with SPSS, but I'd like to play around with the more advanced stuff too (bootstrapping, genetic programming, data mining, neural nets, modeling, etc). I'm looking for a language/environment that can help me run my simpler analyses faster and give me more options than a canned stat package like SPSS. If it can even make tables for me, then it'll be perfect. I also do a fair bit of experimental psychology. I use a canned experiment "programming" software (SuperLab) to make most of my experiments, but I want to be able to program executable programs that I can run on any computer and that can compile the data from the experiments in a spreadsheet. I know python has psychopy and pyepl and matlab has psychtoolbox, but I don't know which one is best. If R had something like this, I'd probably be sold on R already. I'm looking for something regularly used in academe and industry. Everybody else here (including myself, so far) uses canned stat and experiment programming software. One of the reasons I'm trying to learn a programming language is so that I can keep up when I move to another lab. Looking forward to your comments and suggestions. Thank you all for your kind and informative replies. I appreciate it. It's still a tough choice because of so many strong arguments for each language. Python - Thinking about it, I've forgotten so much about C already (I don't even remember what to do with an array) that it might be better for me to start from scratch with a simple program that does what it's supposed to do. It looks like it can do most of the things I'll need it to do, though not as cleanly as R and MATLAB. R - I'm really liking what I'm reading about R. The packages are perfect for my statistical work now. Given the purpose of R, I don't think it's suited to building psychological experiments though. To clarify, what I mean is making a program that presents visual and auditory stimuli to my specifications (hundreds of them in a preset and/or randomized sequence) and records the response data gathered from participants. MATLAB - It's awesome that cognitive and neuro folk are recommending MATLAB, because I'm preparing for the big leap from social and personality psychology to cognitive neuro. The problem is the Uni where I work doesn't have MATLAB licenses (and 3750 GBP for a compiler license is not an option for me haha). Octave looks like a good alternative. PsychToolbox is compatible with Octave, thankfully. SQL - Thanks for the tip. I'll explore that option, too. Python will be the least backbreaking and most useful in the short term. R is well suited to my current work. MATLAB is well suited to my prospective work. It's a tough call, but I think I am now equipped to make a more well-informed decision about where to go next. Thanks again!

  • Does anyone have database, programming language/framework suggestions for a GUI point of sale system

    - by Jason Down
    Our company has a point of sale system with many extras, such as ordering and receiving functionality, sales and order history etc. Our main issue is that the system was not designed properly from the ground up, so it takes too long to make fixes and handle requests from our customers. Also, the current technology we are using (Progress database, Progress 4GL for the language) incurs quite a bit of licensing expenses on our customers due to mutli-user license fees for database connections etc. After a lot of discussion it is looking like we will probably start over from scratch (while maintaining the current product at least for the time being). We are looking for a couple of things: Create the system with a nice GUI front end (it is currently CHUI and the application was not built in a way that allows us to redesign the front end... no layering or separation of business logic and gui...shudder). Create the system with the ability to modularize different functionality so the product doesn't have to include all features. This would keep the cost down for our current customers that want basic functionality and a lower price tag. The bells and whistles would be available for those that would want them. Use proper design patterns to make the product easy to add or change any part at any time (i.e. change the database or change the front end without needing to rewrite the application or most of it). This is a problem today because the Progress 4GL code is directly compiled against the database. Small changes in the database requires lots of code recompiling. Our new system will be Linux based, with a possibility of a client application providing functionality from one or more windows boxes. So what I'm looking for is any suggestions on which database and/or framework or programming language(s) someone might recommend for this sort of product. Anyone that has experience in this field might be able to point us in the right direction or even have some ideas of what to avoid. We have considered .NET and SQL Express (we don't need an enterprise level DB), but that would limit us to windows (as far as I know anyway). I have heard of Mono for writing .NET code in a Linux environment, but I don't know much about it yet. We've also considered a Java and MySql based implementation. To summarize we are looking to do the following: Keep licensing costs down on the technology we will use to develop the product (Oracle, yikes! MySQL, nice.) Deliver a solution that is easily maintainable and supportable. A solution that has a component capable of running on "old" hardware through a CHUI front end. (some of our customers have 40+ terminals which would be a ton of cash in order to convert over to a PC). Suggestions would be appreciated. Thanks [UPDATE] I should note that we are currently performing a total cost analysis. This question is intended to give us a couple of "educated" options to look into to include in or analysis. Anyone who could share experiences/suggestions about client/server setups would be appreciated (not just those who have experience with point of sale systems... that would just be a bonus).

  • ListView: convertView / holder getting confused

    - by Steve H
    I'm working with a ListView, trying to get the convertView / referenceHolder optimisation to work properly but it's giving me trouble. (This is the system where you store the R.id.xxx pointers in as a tag for each View to avoid having to call findViewById). I have a ListView populated with simple rows of an ImageView and some text, but the ImageView can be formatted either for portrait-sized images (tall and narrow) or landscape-sized images (short and wide). It's adjusting this formatting for each row which isn't working as I had hoped. The basic system is that to begin with, it inflates the layout for each row and sets the ImageView's settings based on the data, and includes an int denoting the orientation in the tag containing the R.id.xxx values. Then when it starts reusing convertViews, it checks this saved orientation against the orientation of the new row. The theory then is that if the orientation is the same, then the ImageView should already be set up correctly. If it isn't, then it sets the parameters for the ImageView as appropriate and updates the tag. However, I found that it was somehow getting confused; sometimes the tag would get out of sync with the orientation of the ImageView. For example, the tag would still say portrait, but the actual ImageView would still be in landscape layout. I couldn't find a pattern to how or when this happened; it wasn't consistent by orientation, position in the list or speed of scrolling. I can solve the problem by simply removing the check about convertView's orientation and simply always set the ImageView's parameters, but that seems to defeat the purpose of this optimisation. Can anyone see what I've done wrong in the code below? static LinearLayout.LayoutParams layoutParams; (...) public View getView(int position, View convertView, ViewGroup parent){ ReferenceHolder holder; if (convertView == null){ convertView = inflater.inflate(R.layout.pick_image_row, null); holder = new ReferenceHolder(); holder.getIdsAndSetTag(convertView, position); if (data[position][ORIENTATION] == LANDSCAPE) { // Layout defaults to portrait settings, so ImageView size needs adjusting. // layoutParams is modified here, with specific values for width, height, margins etc holder.image.setLayoutParams(layoutParams); } holder.orientation = data[position][ORIENTATION]; } else { holder = (ReferenceHolder) convertView.getTag(); if (holder.orientation != data[position][ORIENTATION]){ //This is the key if statement for my question switch (image[position][ORIENTATION]) { case PORTRAIT: // layoutParams is reset to the Portrait settings holder.orientation = data[position][ORIENTATION]; break; case LANDSCAPE: // layoutParams is reset to the Landscape settings holder.orientation = data[position][ORIENTATION]; break; } holder.image.setLayoutParams(layoutParams); } } // and the row's image and text is set here, using holder.image.xxx // and holder.text.xxx return convertView; } static class ReferenceHolder { ImageView image; TextView text; int orientation; void getIdsAndSetTag(View v, int position){ image = (ImageView) v.findViewById(R.id.pickImageImage); text = (TextView) v.findViewById(R.id.pickImageText); orientation = data[position][ORIENTATION]; v.setTag(this); } } Thanks!

  • C# Request not timing out

    - by Joel Kennedy
    I have this code which runs in a BackgroundWorker, and should make a POST request to the server and get a response. It works fine when it is supposed to work, but when I try to induce a 404 error it doesn't catch the error reporting system. loginProcess.DoWork += delegate(object s, DoWorkEventArgs args) { // loginProcess BackgroundWorker try { // Try to login, if error, report loginProcess.ReportProgress(10); String method = "POST"; String postdata = "postdata=test"; String url = "http://localhost/dev/login.php"; loginProcess.ReportProgress(15); WebRequest rqst = HttpWebRequest.Create(url); rqst.Timeout = 5000; ((HttpWebRequest)rqst).KeepAlive = true; loginProcess.ReportProgress(20); //rqst.Timeout = this.Timeout; // only needed, if you use HTTP AUTH //CredentialCache creds = new CredentialCache(); //creds.Add(new Uri(url), "Basic", new NetworkCredential(this.Uname, this.Pwd)); //rqst.Credentials = creds; rqst.Method = method; if (!String.IsNullOrEmpty(postdata)) { //rqst.ContentType = "application/xml"; rqst.ContentType = "application/x-www-form-urlencoded"; loginProcess.ReportProgress(30); byte[] byteData = UTF8Encoding.UTF8.GetBytes(postdata); loginProcess.ReportProgress(40); rqst.ContentLength = byteData.Length; loginProcess.ReportProgress(50); using (Stream postStream = rqst.GetRequestStream()) { loginProcess.ReportProgress(50); postStream.Write(byteData, 0, byteData.Length); loginProcess.ReportProgress(60); postStream.Close(); loginProcess.ReportProgress(70); rqst.GetResponse().Close(); rqst.GetRequestStream().Close(); } } loginProcess.ReportProgress(90); using (var response1 = rqst.GetResponse()) { using (var responseStream1 = response1.GetResponseStream()) { using (var reader1 = new StreamReader(responseStream1)) { //StreamReader rsps = new StreamReader(rqst.GetResponse().GetResponseStream()); string strRsps = reader1.ReadToEnd(); loginProcess.ReportProgress(95); loginVars = strRsps; //rqst. //reader1.Close(); //rsps.Dispose(); } args.Result = "SUCCESS"; } } } catch(WebException err) { // Catch error and put into err variable if(err.Status == WebExceptionStatus.ProtocolError) { // If something is wrong with protocol LoginReporting.ErrorName = Convert.ToString(((HttpWebResponse)err.Response).StatusCode); LoginReporting.ErrorDescription = Convert.ToString(((HttpWebResponse)err.Response).StatusDescription); LoginReporting.ErrorNotes = "Error when logging in, Server returned: " + Convert.ToString(((HttpWebResponse)err.Response).StatusCode); LoginReporting.ErrorLocation = "LoginRequest.ProtocolError"; args.Result = "ERROR"; //MessageBox.Show(Convert.ToString(((HttpWebResponse)err.Response).StatusCode)); //MessageBox.Show(Convert.ToString(((HttpWebResponse)err.Response).StatusDescription)); } else { args.Result = "ERROR"; } } catch(Exception err) { // Catch unhandled error LoginReporting.ErrorName = Convert.ToString(err); LoginReporting.ErrorDescription = Convert.ToString(err.Message); LoginReporting.ErrorNotes = "Error when logging in, Server returned: " + Convert.ToString(err.Message); LoginReporting.ErrorLocation = "LoginRequest.ProtocolError"; args.Result = "ERROR"; } }; I have put a timeout on the request but it just doesn't work! Is this a bug, or am I doing something wrong here? Thanks

  • Search engine solution for Django that actually works?

    - by prometheus
    The story so far: Decided to go with Xapian as search backend because it has all search-engine features I was looking for, knows about Unicode, stemming, has few dependencies and requires no bloated app-server installation on top of it. Tried Django and Haystack (plus xapian-haystack, the backend glue code to tie Haystack to Xapian) because it was advertised on quite some blogs as "working". Did not work. Neither django-haystack nor the xapian-haystack project provide a version combination that actually works together. MASTER from both projects yields an error from Xapian, so it's not stable at all. Haystack 1.0.1 and xapian-haystack 1.0.x/1.1.0 are not API-compatible. Plus, in a minimally working installation of Haystack 1.0.1 and xapian-haystack MASTER, any complex query yields zero results due to errors in either django-haystack or xapian-haystack (I double-verified this), maybe because the unit-tests actually test very simple cases, and no edge-cases at all. Tried Djapian. The source-code is riddled with spelling errors (mind you, in variable names, not comments), documentation is also riddled with ambiguities and outdated information that will never lead to a working installation. Not surprisingly, users rarely ask for features but how to get it working in the first place. Next on the plate: exploring Solr (installing a Java environment plus Tomcat gives me headaches, the machine is RAM- and CPU-constrained), or Lucene (slightly less headaches, but still). Before I proceed spending more time with a solution that might or might not work as advertised, I'd like to know: Did anyone ever get an actual, real-world search solution working in Django? I'm serious. I find it really frustrating reading about "large problems mostly solved", and then realizing that you will never get a working installation from the source-code because, actually, all bloggers dealing with those "mostly solved problems" never went past basic installation and copy-pasting the official tutorials. So here are the requirements: must be able to search for 10-100 terms in one query must handle + (term must be present) and - (term must not be present), AND/OR must handle arbitrary grouping (i.e. parentheses around AND/OR) must allow for Django-ORM filtering before or after fulltext-search (i.e. pre-/post-processing of results with the full set of filters that Django knows about) alternatively, there must be a facility to bulk-fetch the result set and transform it into a QuerySet should be light on the machine, so preferably no humongous JVM and Java-based app-server installation Is there anything out there that does this? I'm not interested in anecdotal evidence, or references to some blog posts that claim it should be working. I'd like to hear from someone who actually has a fully-functional setup working in the real world, under real conditions, with real queries. EDIT: Let me repeat again that I'm not so much interested in anecdotal evidence that someone, somewhere has a somewhat running installation working with unspecified properties. I already went there, I read all the blog posts, mailing lists, I contacted the authors, but when it came to actual implementation of real-world scenarios, nothing ever worked as advertised. Also, and a user below brought that point up as well, considering the TCO of any project, I'm definitely not interested in hearing that someone, somewhere was able to pull it off once a vendor parachuted in an unknown number of specialists to monkey-patch the whole installation with specific domain-knowledge that's documented nowhere. So, please, if you claim you have a working installation that actually satisfies minimum requirements for a full-fledged search (see requirements above), please provide the following so that we can all benefit from a search solution for Django that actually solves the problem: exact Linux distribution, release version, exact release version of Haystack (or equivalent) and release version of search backend, exact release version of the search engine publicly (!) available documentation how to set up all components exactly in the way that your installation was set up such that the minimal requirements above are met. Thank you.

  • How to make a css navigation menu "selected" option still clickable

    - by aslum
    So I have a fairly simple vertical CSS menu based off of UL. <ul class="vertnav"> <li><a href="unselected1.php">Item1</a></li> <li><a href="unselected2.php">Item2</a></li> <li><a href="selected.php" class="vertnavdown">Selected</a></li> </ul> I want three basic colors (say tan for default LI, orange for VERTNAVDOWN, and red for A:HOVER. However I can't seem to get the vertnavdown class to inherit right, and the .vertnav li a:visited overrides it every time. if I use !important to force it through I can't seem to also get the hover to work. Any suggestions? I thought I understood inheritance in CSS but I guess I don't. .vertnav{ list-style: none; margin: 0px; width: 172px; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; padding: 0px 0px 0px 0px; margin: 0px 0px 0px 0px; text-align: left; height: 45px; } .vertnav li{ margin: 0px; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; border-bottom: 0px none; border-right: 0px none; border-top: 1px solid #fff; border-left: 0px none; text-align: left; height: 45px; width: 172px; padding: 0px 0px 0px 0px; margin: 0px 0px 0px 0px; } .vertnav li a{ display: block; text-align: left; color: #666666; font-weight: bold; background-color: #FFEEC1; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; text-decoration: none; padding-top: 10px; padding-right: 0px; padding-bottom: 0px; padding-left: 15px; height: 45px; } .vertnav li a:visited{ display: block; text-align: left; color: #666666; background-color: #FFEEC1; font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 11px; font-weight: bold; text-decoration: none; padding-top: 10px; padding-right: 0px; padding-bottom: 0px; padding-left: 15px; height: 45px; } .vertnav li a:hover{ color: white; background-color: #ffbf0c; font-family: Verdana, Arial, Helvetica, sans-serif; height: 45px; text-decoration: none; font-weight: bold; } .vertnavdown a { display:block; color: #FFF; background-color: #ff9000; } .vertnavdown a:hover { background-color: #ffbf0c; } ^^^^^^^^^^^^^ Edited to add CSS. ^^^^^^

  • LLVM JIT segfaults. What am I doing wrong?

    It is probably something basic because I am just starting to learn LLVM..

But I get segmentation fault upon execution of the function (in EE-runFunction(TheF, Args)) #include <iostream> #include "llvm/Module.h" #include "llvm/Function.h" #include "llvm/PassManager.h" #include "llvm/CallingConv.h" #include "llvm/Analysis/Verifier.h" #include "llvm/Assembly/PrintModulePass.h" #include "llvm/Support/IRBuilder.h" #include "llvm/Support/raw_ostream.h" #include "llvm/ExecutionEngine/JIT.h" #include "llvm/ExecutionEngine/GenericValue.h" using namespace llvm; Module* makeLLVMModule() { // Module Construction LLVMContext& ctx = getGlobalContext(); Module* mod = new Module("test", ctx); Constant* c = mod->getOrInsertFunction("fact64", /*ret type*/ IntegerType::get(ctx,64), IntegerType::get(ctx,64), /*varargs terminated with null*/ NULL); Function* fact64 = cast<Function>(c); fact64->setCallingConv(CallingConv::C); /* Arg names */ Function::arg_iterator args = fact64->arg_begin(); Value* x = args++; x->setName("x"); /* Body */ BasicBlock* block = BasicBlock::Create(ctx, "entry", fact64); BasicBlock* xLessThan2Block= BasicBlock::Create(ctx, "xlst2_block", fact64); BasicBlock* elseBlock = BasicBlock::Create(ctx, "else_block", fact64); IRBuilder<> builder(block); Value *One = ConstantInt::get(Type::getInt64Ty(ctx), 1); Value *Two = ConstantInt::get(Type::getInt64Ty(ctx), 2); Value* xLessThan2 = builder.CreateICmpULT(x, Two, "tmp"); //builder.CreateCondBr(xLessThan2, xLessThan2Block, cond_false_2); builder.CreateCondBr(xLessThan2, xLessThan2Block, elseBlock); /* Recursion */ builder.SetInsertPoint(elseBlock); Value* xMinus1 = builder.CreateSub(x, One, "tmp"); std::vector<Value*> args1; args1.push_back(xMinus1); Value* recur_1 = builder.CreateCall(fact64, args1.begin(), args1.end(), "tmp"); Value* retVal = builder.CreateBinOp(Instruction::Mul, x, recur_1, "tmp"); builder.CreateRet(retVal); /* x<2 */ builder.SetInsertPoint(xLessThan2Block); builder.CreateRet(One); return mod; } int main(int argc, char**argv) { long long x; if(argc > 1) x = atol(argv[1]); else x = 4; Module* Mod = makeLLVMModule(); verifyModule(*Mod, PrintMessageAction); PassManager PM; PM.add(createPrintModulePass(&outs())); PM.run(*Mod); // Now we going to create JIT ExecutionEngine *EE = EngineBuilder(Mod).create(); // Call the function with argument x: std::vector<GenericValue> Args(1); Args[0].IntVal = APInt(64, x); Function* TheF = cast<Function>(Mod->getFunction("fact64")) ; /* The following CRASHES.. */ GenericValue GV = EE->runFunction(TheF, Args); outs() << "Result: " << GV.IntVal << "\n"; delete Mod; return 0; }

  • How Do I Bind a "selected Item" in a Listbox to a ItemsControl in WPF?

    - by Scott
    LowDown: I am trying to create a Document Viewer in WPF. It will allow the user to preview selected documents and if they want, compare the documents in WPF. So they can view them side by side. The layout is this: Left side is a full list box. On the right side is a Collection or an Items control. Inside the items control will be a collection of the "selected documents" in the list box. So A user can select multiple items in the list box and for each new item they select, they can add the item to the collection on the right. I want the collection to look like a image gallery that shows up in Google/Bing Image searches. Make sense? The problem I am having is I can't get the WPFPreviewer to bind correctly to the selected item in the list box under the itemscontrol. Side Note: The WPFPreviewer is something Micorosft puts out that allows us to preview documents. Other previewers can be built for all types of documents, but im going basic here until I get this working right. I have been successful in binding to the list box WITHOUT the items control here: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid Background="Cyan"> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <l:WPFPreviewHandler Content="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}"/> </Grid> Though, once I add in the ItemsControl, I can't get it to work anymore: <Window.Resources> <DataTemplate x:Key="listBoxTemplate"> <StackPanel Margin="3" > <DockPanel > <Image Source="{Binding IconURL}" Height="30"></Image> <TextBlock Text=" " /> <TextBlock x:Name="Title" Text="{Binding Title}" FontWeight="Bold" /> <TextBlock x:Name="URL" Visibility="Collapsed" Text="{Binding Url}"/> </DockPanel> </StackPanel> </DataTemplate> </Window.Resources> <Grid> <ListBox HorizontalAlignment="Left" ItemTemplate="{StaticResource listBoxTemplate}" Width="200" AllowDrop="True" x:Name="lbDocuments" ItemsSource="{Binding Path=DocumentElements,ElementName=winDocument}" DragEnter="documentListBox_DragEnter" /> <ItemsControl x:Name="DocumentViewer" ItemsSource="{Binding ElementName=lbDocuments, Path=SelectedItem.Url}" > <ItemsControl.ItemTemplate> <DataTemplate> <Grid Background="Cyan"> <l:WPFPreviewHandler Content="{Binding Url}"/> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> </Grid> Can someone please help me out with trying to bind to the ItemsControl if I select one or even multiple items in the listbox.

  • Outlook Plug-In for custom CRM

    - by Optimal Solutions
    I would like to write a plug-in that will allow a custom written CRM to read and write to their local Outlook client. I know that this poses a security concern. But, my clients are asking that their CRM "be connected" to Outlook. They would like to be able to do the following: A) When a contact sends them an email (reply or free standing email), they'd like the details of this email to go INTO the CRM. Yep. They would like me to save the body, time and date it was sent, etc. B) They want to be able to send new emails (or replies to existing emails) from within the CRM itself. Basically, "a form that looks like Outlook's send/reply email form". C) Want the ability to search for contacts and the related emails with a search for tags/keywords facility. (i.e. if a product name or code appears in an email then they want the email returned in the search). D) Having performed a search of many contacts, they will want to prepare a mailer and shoot out some sort of email announcement to their qualified leads. This could be 50, 100, or more persons. So its got to be able to allow bulk mailing. E) Given a list of new prospects, that arent currently contacts in the CRM, they will want to do the same and if they get replies from this mailer to the prospects, the will want the replies to be saved in the DB and contacts be inserted into the DB. F) They would like to be able to utilize the calendar and task list facilities of Outlook from the CRM, as well. More or less, they want this pretty basic (as it is today) CRM that I created to integrate with Outlook and have it do so seamlessly as if it was an add-on to the CRM. A plug-in is what I am thinking... But, I dont know where to begin. My environment is Windows XP/Vista and is going to be ASP.NET and I am going to use the VB.NET language to accomplish this. What do I need? Are there resources out there that can describe how to build a plug-in to Outlook as I have been asked to? This is not Exchange, none of the clients use exchange (not so far). They all run Outlook. Mostly 2003. Most clients are XP right now but some are upgrading to Vista. For some reason I cant seem to wrap my head around this. I think the whole security issue is thwarting my ability to see past what is probably a simple thing. The client doesnt want to be prompted by any security messages asking them if they are sure they want to send 382 emails to their contacts. Not once and certainly not 382 times. Where do I begin? I've searched the internet for similar but mainly what I found are already-written products and I've got to write this from scratch.
