  • php soapclient returns null but getPreviousResults has proper results

    - by Joseph.Chambers
    I've ran into trouble with SOAP, I've never had this issue before and can't find any information on line that helps me solve it. The following code $wsdl = "path/to/my/wsdl"; $client = new SoapClient($wsdl, array('trace' => true)); //$$textinput is passed in and is a very large string with rows in <item></item> tags $soapInput = new SoapVar($textinput, XSD_ANYXML); $res = $client->dataprofilingservice(array("contents" => $soapInput)); $response = $client->__getLastResponse(); var_dump($res);//outputs null var_dump($response);//provides the proper response as I would expect. I've tried passing params into the SoapClient constructor to define soap version but that didnt' help. I've also tried it with the trace param set to false and not present which as expected made $response null but $res was still null. I've tried the code on both a linux and windows install running Apache. The function definition in the WSDL is (xxxx is for security reasons) <portType name="xxxxServiceSoap"> <operation name="dataprofilingservice"> <input message="tns:dataprofilingserviceSoapIn"/> <output message="tns:dataprofilingserviceSoapOut"/> </operation> </portType> I have it working using the __getLastResponse() but its annoying me it will not work properly. I've put together a small testing script, does anyone see any issues here. //very simplifed dataset that would normally be //read in from a CSV file of about 1mb $soapInput = getSoapInput("asdf,qwer\r\nzzxvc,ewrwe\r\n23424,2113"); $wsdl = "path to wsdl"; try { $client = new SoapClient($wsdl,array('trace' => true,'exceptions' => true)); } catch (SoapFault $fault) { $error = 1; var_dump($fault); } try { $res = $client->dataprofilingservice(array("contents" => $soapInput)); $response = $client->__getLastResponse(); echo htmlentities($client->__getLastRequest()); echo '<hr>'; var_dump($res); echo "<hr>"; echo(htmlentities($response)); } catch (SoapFault $fault) { $error = 1; var_dump($fault); } function getSoapInput($input){ $rows = array(); $userInputs = explode("\r\n", $input); $userInputs = array_filter($userInputs); // $inputTemplate = " <contents>%s</contents>"; $rowTemplate = "<Item>%s</Item>"; // $soapString = ""; foreach ($userInputs as $row) { // sanitize $row = htmlspecialchars(addslashes($row)); $xmlStr = sprintf($rowTemplate, $row); $rows[] = $xmlStr; } $textinput = sprintf($inputTemplate, implode(PHP_EOL, $rows)); $soapInput = new SoapVar($textinput, XSD_ANYXML); return $soapInput; }

  • Doubly linked lists

    - by user1642677
    I have an assignment that I am terribly lost on involving doubly linked lists (note, we are supposed to create it from scratch, not using built-in API's). The program is supposed to keep track of credit cards basically. My professor wants us to use doubly-linked lists to accomplish this. The problem is, the book does not go into detail on the subject (doesn't even show pseudo code involving doubly linked lists), it merely describes what a doubly linked list is and then talks with pictures and no code in a small paragraph. But anyway, I'm done complaining. I understand perfectly well how to create a node class and how it works. The problem is how do I use the nodes to create the list? Here is what I have so far. public class CardInfo { private String name; private String cardVendor; private String dateOpened; private double lastBalance; private int accountStatus; private final int MAX_NAME_LENGTH = 25; private final int MAX_VENDOR_LENGTH = 15; CardInfo() { } CardInfo(String n, String v, String d, double b, int s) { setName(n); setCardVendor(v); setDateOpened(d); setLastBalance(b); setAccountStatus(s); } public String getName() { return name; } public String getCardVendor() { return cardVendor; } public String getDateOpened() { return dateOpened; } public double getLastBalance() { return lastBalance; } public int getAccountStatus() { return accountStatus; } public void setName(String n) { if (n.length() > MAX_NAME_LENGTH) throw new IllegalArgumentException("Too Many Characters"); else name = n; } public void setCardVendor(String v) { if (v.length() > MAX_VENDOR_LENGTH) throw new IllegalArgumentException("Too Many Characters"); else cardVendor = v; } public void setDateOpened(String d) { dateOpened = d; } public void setLastBalance(double b) { lastBalance = b; } public void setAccountStatus(int s) { accountStatus = s; } public String toString() { return String.format("%-25s %-15s $%-s %-s %-s", name, cardVendor, lastBalance, dateOpened, accountStatus); } } public class CardInfoNode { CardInfo thisCard; CardInfoNode next; CardInfoNode prev; CardInfoNode() { } public void setCardInfo(CardInfo info) { thisCard.setName(info.getName()); thisCard.setCardVendor(info.getCardVendor()); thisCard.setLastBalance(info.getLastBalance()); thisCard.setDateOpened(info.getDateOpened()); thisCard.setAccountStatus(info.getAccountStatus()); } public CardInfo getInfo() { return thisCard; } public void setNext(CardInfoNode node) { next = node; } public void setPrev(CardInfoNode node) { prev = node; } public CardInfoNode getNext() { return next; } public CardInfoNode getPrev() { return prev; } } public class CardList { CardInfoNode head; CardInfoNode current; CardInfoNode tail; CardList() { head = current = tail = null; } public void insertCardInfo(CardInfo info) { if(head == null) { head = new CardInfoNode(); head.setCardInfo(info); head.setNext(tail); tail.setPrev(node) // here lies the problem. tail must be set to something // to make it doubly-linked. but tail is null since it's // and end point of the list. } } } Here is the assignment itself if it helps to clarify what is required and more importantly, the parts I'm not understanding.

  • Android 1.6: "android.view.WindowManager$BadTokenException: Unable to add window -- token null is no

    - by Dan Monego
    I'm trying to open a dialog window, but every time I try to open it it throws this exception: E/AndroidRuntime( 206): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 206): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application E/AndroidRuntime( 206): at android.view.ViewRoot.setView(ViewRoot.java:460) E/AndroidRuntime( 206): at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:177) E/AndroidRuntime( 206): at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:91) E/AndroidRuntime( 206): at android.app.Dialog.show(Dialog.java:238) E/AndroidRuntime( 206): at android.app.Activity.showDialog(Activity.java:2413) I'm creating it by calling showDialog with the display's id. The onCreateDialog handler logs fine and I can step through it without an issue, but I've attached since it seems like I'm missing something in it: @Override public Dialog onCreateDialog(int id) { Dialog dialog; Context appContext = this.getApplicationContext(); switch(id) { case RENAME_DIALOG_ID: Log.i("Edit", "Creating rename dialog..."); dialog = new Dialog(appContext); dialog.setContentView(R.layout.rename); dialog.setTitle("Rename " + noteName); break; default: dialog = null; break; } return dialog; } Is there something missing from this? Some questions have talked about having this problem when creating a dialog from onCreate, which happen because the activity isn't created yet, but this is coming from a call from a menu object, and the appContext variable seems like it is correctly populated in the debugger.

  • ReSharper - Possible Null Assignment when using Microsoft.Contracts

    - by HVS
    Is there any way to indicate to ReSharper that a null reference won't occur because of Design-by-Contract Requires checking? For example, the following code will raise the warning (Possible 'null' assignment to entity marked with 'NotNull' attribute) in ReSharper on lines 7 and 8: private Dictionary<string, string> _Lookup = new Dictionary<string, string>(); public void Foo(string s) { Contract.Requires(!String.IsNullOrEmpty(s)); if (_Lookup.ContainsKey(s)) _Lookup.Remove(s); } What is really odd is that if you remove the Contract.Requires(...) line, the ReSharper message goes away. Update I found the solution through ExternalAnnotations which was also mentioned by Mike below. Here's an example of how to do it for a function in Microsoft.Contracts: Create a directory called Microsoft.Contracts under the ExternalAnnotations ReSharper directory. Next, Create a file called Microsoft.Contracts.xml and populate like so: <assembly name="Microsoft.Contracts"> <member name="M:System.Diagnostics.Contracts.Contract.Requires(System.Boolean)"> <attribute ctor="M:JetBrains.Annotations.AssertionMethodAttribute.#ctor"/> <parameter name="condition"> <attribute ctor="M:JetBrains.Annotations.AssertionConditionAttribute.#ctor(JetBrains.Annotations.AssertionConditionType)"> <argument>0</argument> </attribute> </parameter> </member> </assembly> Restart Visual Studio, and the message goes away!

  • jQuery.ajax call to Twitter succeeds but returns null for Firefox

    - by Zhami
    I've got code that makes a simple get request to Twitter (search) using jQuery's ajax method. The code works fine on Safari, but fails on Firefox (3.6.3). In the Firefox case, my jQuery.ajax parameters 'success' method is invoked, but the supplied data is null. (In Safari, I receive a boatload of JSON data). My ajax call is: $.ajax({ url: 'http://search.twitter.com/search.json?q='+searchTerm, dataType: 'json', async: true, beforeSend: function(request) { window.console.log('starting AJAX request to get Twitter data'); }, success: function(data, textStatus, request) { window.console.log('AJAX request to get Twitter succeeded: status=' + textStatus); callback(data); }, error: function(request, status, error) { window.console.log('AJAX request to get user data --> Error: ' + status); errback(request, status, error); } }); Firebug shows Response headers: Date Sun, 11 Apr 2010 22:30:26 GMT Server hi Status 200 OK X-Served-From b021 X-Runtime 0.23841 Content-Type application/json; charset=utf-8 X-Served-By sjc1o024.prod.twitter.com X-Timeline-Cache-Hit Miss Cache-Control max-age=15, must-revalidate, max-age=300 Expires Sun, 11 Apr 2010 22:35:26 GMT Vary Accept-Encoding X-Varnish 1827846877 Age 0 Via 1.1 varnish X-Cache-Svr sjc1o024.prod.twitter.com X-Cache MISS Content-Encoding gzip Content-Length 2126 Connection close The HTTP status is OK (200), the Conetnt-Type is properly application/json, and the Content-Length of 2126 (gzip'd) implies data came back. Yet Firebug shows the Response to be empty, and a test of the supplied data shows it o be 'null.' I am aware of a similar post on Stack Overflow: http://stackoverflow.com/questions/1188976/jquery-get-function-succeeds-with-200-but-returns-no-content-in-firefox and from that would assume this problem is possibly related to cross-domain security, but... I know there are many JS widgets and whatnots that ajax get data from Twitter. Is there something I need to enable to allow this?

  • OpenSSL.NET can't export private key with null Cipher

    - by Nick
    I've recently discovered OpenSSL.NET and it's a pretty sweet little wrapper. I'm trying to execute the following code: public static void DoSomething(byte[] buf) { OpenSSL.Core.BIO input = new OpenSSL.Core.BIO(buf); OpenSSL.X509.X509Certificate b = OpenSSL.X509.X509Certificate.FromPKCS12(input, "passphrase"); OpenSSL.Core.BIO outs = OpenSSL.Core.BIO.MemoryBuffer(false); b.PrivateKey.WritePrivateKey(outs, OpenSSL.Crypto.Cipher.Null, "passphrase"); outs.SetClose(OpenSSL.Core.BIO.CloseOption.Close); Console.WriteLine(outs.ReadString()); } Problem comes at the "b.PrivateKey.WritePrivateKey(.." line. I want to write the private key out without any encryption. According to spec, if I use a Null cipher type this should do the trick, but it never works, regardless of the cert I use in buf. Here's the exception: error:0D0A706C:asn1 encoding routines:PKCS5_pbe2_set:cipher has no object identifier error:2307D00D:PKCS12 routines:PKCS8_encrypt:ASN1 lib I know this part works fine because if I specify any other cipher type, it exports the private key without fail. Anyone have any suggestions?

  • Android - Views in Custom Compound Component are not inflated (findByView returns null)

    - by Julian Arz
    I have made a Custom Component in XML, consisting of a button with an imageview stacked on top of it: <myapp.widget.ClearableCaptionedButton xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <Button android:id="@+id/ccbutton_button" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center_vertical|left" android:textAppearance="?android:attr/textAppearanceMedium" android:background="@android:drawable/edit_text"/> <ImageView android:id="@+id/ccbutton_clear" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="5dip" android:layout_alignRight="@id/ccbutton_button" android:layout_alignTop="@id/ccbutton_button" android:layout_alignBottom="@id/ccbutton_button"/> </myapp.widget.ClearableCaptionedButton> extract of java source code: public class ClearableCaptionedButton extends RelativeLayout implements OnClickListener { ... public ClearableCaptionedButton(Context context, AttributeSet attrs) { super(context, attrs); // some stuff that works fine } .. protected void onFinishInflate() { super.onFinishInflate(); mButton = (Button) findViewById(R.id.ccbutton_button); mClear = (ImageView) findViewById(R.id.ccbutton_clear); mButton.setText(""); // error here: mButton == null } My problem is similar to this one. When i try to find the views inside the custom compound, findViewById returns null. But, as you can see, i already added super(context, attrs); to the constructor. i am using the custom component directly in xml layout, like this: <LinearLayout> <!-- some stuff --> <de.pockettaxi.widget.ClearableCaptionedButton android:layout_width="fill_parent" android:layout_height="wrap_content" app:caption="to"/> </LinearLayout> can anybody spot something? thanks.

  • ASP.NET MVC TextBoxFor helper rendering empty when null

    - by mare
    I noticed that TextBoxFor helper renders empty if there is no model, like for instance when I have a CreateEdit ViewUserControl. When in Edit view fields are filled in, when in Create fields are empty but still rendered. The problem is TextBoxFor does not accept different Id for its name (the same as LabelFor and others, but for LabelFor I have custom Html helpers). So in some case we still have to use regular Html.TextBox helper. The problem is if I write this <%=Html.TextBox("postname", Model.PostCode.postname, new { @class = "postsDropDown" })%> an error occurs in Create view (obviously). So I have to do this: <% if (Model != null) %> <%=Html.TextBox("postname", Model.PostCode.postname, new { @class = "postsDropDown" })%> <% else %> <%=Html.TextBox("postname", null, new { @class = "postsDropDown" })%> Now that is something which I don't like anymore (the IF's). Is this the only way to do it? I know I could extend TextBoxFor helpers also but seems like so much trouble. In the end we will come to extending all of the "For" helpers but I think this should be done by ASP.NET MVC team already (built-in).

  • Only first table in create table statement being created

    The table "credentials" does show up in the adb shell.

  • Servlet receives null from Remote EJB3 Session Bean

    - by Hank
    I'm sure this is a beginner error... So I have a JEE6 application with entities, facades (implementing the persistence layer) and Stateless Session Beans (EJB3) with Remote interfaces (providing access to the entities via facades). This is working fine. Via the SLSB I can retrieve and manipulate entities. Now, I'm trying to do this from a Web Application (deployed on the same Glassfish, entity+interface definitions from JEE app imported as separate jar). I have a Servlet, that receives an instance of the SLSB injected. I get it to retrieve an entity, and the following happens (I can see it in the logs): the remote SLSB gets instantiated, its method called SLSB instantiates the facade, calls the 'get' method facade retrieves object from DB, returns it SLSB returns the object to the caller (all is good until here) calling servlet receives .. null !! What is going wrong? This should work, right? MyServlet: public class MyServlet extends HttpServlet { @EJB private CampaignControllerRemote campaignController; // remote SLSB protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.setContentType("text/plain"); PrintWriter out = response.getWriter(); try { Campaign c = campaignController.getCampaign(5L); // id of an existing campaign out.println("Got "+ c.getId()); // c is null !! } finally { out.close(); } } ... } Pls let me know if you want to see other code, and I'll update the post.

  • Use Java exceptions internally for REST API user errors?

    - by user303396
    We have a REST API that works great. We're refactoring and deciding how to internally handle errors by the users of our API. For example the user needs to specify the "movie" url parameter which should take the value of "1984", "Crash", or "Avatar". First we check to see if it has a valid value. What would be the best approach if the movie parameter is invalid? return null from one of the internal methods and check for the null in the main API call method throw an exception from the internal method and catch exceptions in the main API method I think it would make our code more readable and elegant to use exceptions. However, we're reluctant because we'd be potentially throwing many exceptions because of user API input errors, our code could be perfect. This doesn't seem to be the proper use of exceptions. If there are heavy performance penalties with exceptions, which would make sense with stack traces needing to be collected, etc., then we're unnecessarily spending resources when all we need to do is tell the user the parameter is wrong. These are REST API methods, so we're not propogating the exceptions to the users of the API, nor would we want to even if possible. So what's the best practice here? Use ugly nulls or use java's exception mechanism?

  • Controls added in the designer are null during Page_Load

    - by mwright
    All of the names below are generic and not the actual names used. I have a custom UserControl with a Panel that contains a a couple Labels, both .aspx controls. .aspx: <asp:Panel runat="server"> <asp:Label ID="label1" runat="server"> </asp:Label> </asp:Panel> <asp:Panel runat="server"> <asp:Label ID="label2" runat="server"> </asp:Label> </asp:Panel> Codebehind: private readonly Object object; protected void Page_Load(object sender, EventArgs e) { // These are the lines that are failing // label1 and label2 are null label1.Text = object.Value1; label2.Text = object.Value2; } public ObjectRow(Object objectToDisplay) { object = objectToDisplay; } On another page, in the code behind, I create a new instance of the custom user control. protected void Page_Load(object sender, EventArgs e) { CustomControl control = new CustomControl(object); } The user control takes the parameter and attempts to set the labels based off of the object passed in. The labels that it tries to assign the values to are however, null. Is this an ASP.net lifecycle issue that I'm not understanding? My understanding based on the Microsoft ASP.net lifecycle page was that page controls were available after the Page_Initialization. What is the proper way to do this? Is there a better way?

  • Why is PackageInfo.requestedPermissions always null?

    - by Luke
    I'm trying to enumerate all the permissions used by all the installed packages, however when I check the requestedPermissions property for each of my installed packages it is always null. The following is the code that does this: private HashMap<String, List<String>> buildMasterList() { HashMap<String, List<String>> result = new HashMap<String, List<String>>(); List<PackageInfo> packages = getPackageManager().getInstalledPackages(PackageManager.GET_PERMISSIONS); for (int i = 0; i < packages.size(); i++) { String[] packagePermissions = packages.get(i).requestedPermissions; Log.d("AppList", packages.get(i).packageName); if (packagePermissions != null) { for (int j = 0; j < packagePermissions.length; j++) { if (!result.containsKey(packagePermissions[j])) { result.put(packagePermissions[j], new ArrayList<String>()); } result.get(packagePermissions[j]).add(packages.get(i).packageName); } } else { Log.d("AppList", packages.get(i).packageName + ": no permissions"); } } return result; } Edit: Oops! I just needed to pass the PackageManager.GET_PERMISSIONS flag to getInstalledPackages(). Updated the code snippet.

  • Inserting null fields with dbi:Pg

    - by User1
    I have a Perl script inserting data into Postgres according to a pipe delimited text file. Sometimes, a field is null (as expected). However, Perl makes this field into an empty string and the Postgres insert statement fails. Here's a snippet of code: use DBI; #Connect to the database. $dbh=DBI-connect('dbi:Pg:dbname=mydb','mydb','mydb',{AutoCommit=1,RaiseError=1,PrintError=1}); #Prepare an insert. $sth=$dbh-prepare("INSERT INTO mytable (field0,field1) SELECT ?,?"); while (<){ #Remove the whitespace chomp; #Parse the fields. @field=split(/\|/,$_); print "$_\n"; #Do the insert. $sth-execute($field[0],$field[1]); } And if the input is: a|1 b| c|3 EDIT: Use this input instead. a|1|x b||x c|3|x It will fail at b|. DBD::Pg::st execute failed: ERROR: invalid input syntax for integer: "" I just want it to insert a null on field1 instead. Any ideas? EDIT: I simplified the input at the last minute. The old input actually made it work for some reason. So now I changed the input to something that will make the program fail. Also note that field1 is a nullable integer datatype.

Any suggestions? Thank you

  • .NET: Allow NULLS in DB fields?

    - by mark smith
    Hi there, I have the task of re-factoring an SQLServer DB.... A lot of the tables and columns "ALLOW NULLS", Is this good practice... I seem to remember the authour of CSLA.NET saying it was really bad practice to allow nulls in a DB... If this is the case, what are my alternatives? Remove all "ALLOW NULLS" from all columns.... and in numeric columns use a value of -1 for example?? I would really appreciate any input anyone has. I am currently using a Model (from entity framework) from my DB and the db columns that "ALLOW NULLS" are null ... and some of the stored procedures require that i have a default value... i.e. BOOLEAN require FALSE as default ... but it is null.. Well i don't want to stray from my original question, ALLOW NULLS are a bad thing from what i can gather .... so how do i fix this ? Any help really appreciated

Now I've added the: <filter> <filter-name>myautologinfilter</filter-name> <filter-class>bla.bla.xyz</filter-class> </filter> <filter-mapping> <filter-name>myautologinfilter</filter-name> <url-pattern>/c/login/myurl</url-pattern> </filter-mapping> To the liferay hook's web.xml. In the liferay-hook.xml I added: portal.properties And in that hook.xml I added: auto.login.hooks=bla.bla.xyz bla.bla.xyz implements AutoLogin, but for now it's pretty gutted: @Override public String[] login(HttpServletRequest request, HttpServletResponse response) throws AutoLoginException { Object parameters = request.getAttribute("javax.servlet.forward.query_string"); Map<String, String> x = parserClass.parsing(parameters.toString()); System.out.println("voornaam: " + geparsdeParameters.get("tokenvalue1")); try { return null; } catch (Exception e) { throw new AutoLoginException(e); } } Since the hook doesn't start when I add the filtering I removed it and just tried: http://localhost:8080/c/portal/login?tokenvalue1=55 but when I check my tomcat I see: Error XYZ Url: url myUsedUrl exception null Also I tried adding some util classes but I got: classnotfoundexceptions. Is there anything specific I have to do when I add extra classes in a hook? Any advice/input would be appreciated. Or someone's ear I could lend so I could mail them a little bit so I could pick their brain a bit would be really appreciated since I don't know anyone who programs for liferay.

  • rich suggestions - why input is null? (seam framework)

    - by Cristian Boariu
    Hi, I'm trying to build a rich suggestions and i do not understand WHY the input value is null... I mean, why inputText value is not taken when i enter something. The .xhtml code: <h:inputText value="#{suggestion.input}" id="text"> </h:inputText> <rich:suggestionbox id="suggestionBoxId" for="text" tokens=",[]" suggestionAction="#{suggestion.getSimilarSpacePaths()}" var="result" fetchValue="#{result.path}" first="0" minChars="2" nothingLabel="No similar space paths found" columnClasses="center" > <h:column> <h:outputText value="#{result.path}" style="font-style:italic"/> </h:column> </rich:suggestionbox> and action class: @Name("suggestion") @Scope(ScopeType.CONVERSATION) public class Suggestion { @In protected EntityManager entityManager; private String input; public String getInput() { return input; } public void setInput(final String input) { this.input = input; } public List<Space> getSimilarSpacePaths() { List<Space> suggestionsList = new ArrayList<Space>(); if (!StringUtils.isEmpty(input) && !input.equals("/")) { final Query query = entityManager.createNamedQuery("SpaceByPathLike"); query.setParameter("path", input + '%'); suggestionsList = (List<Space>) query.getResultList(); } return suggestionsList; } } So, input beeing null, suggestionList is always empty... Why input's value is not posted?

  • Origin null is not allowed by Access-Control-Allow-Origin

    - by JIGGABITS
    I'm currently working with the SoundCloud API and would like to have a track embed when a button is clicked. I get two errors: XMLHttpRequest cannot load http://soundcloud.com/oembed.json?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F48419073. Origin null is not allowed by Access-Control-Allow-Origin. AND Uncaught TypeError: Cannot read property 'html' of null Here is my code: <button onclick="getPopular()">+1</button> <div id="track"></div> <script src="http://connect.soundcloud.com/sdk.js" type="text/JavaScript"></script> <script type="text/JavaScript"> SC.initialize({ client_id: "**************", }); var getPopular = function() { SC.get("/tracks", {limit: 1}, function(tracks) { var track = tracks[0]; alert("Latest track: " + track.title); SC.oEmbed(track.uri, document.getElementById("track")); }); }; </script> I use an alert in my code to let me know that it is actually taking information from the SoundCloud API. I'm just not sure what else is preventing it from embedding. Thanks, ahead of time, or looking at my question. jiggabits

  • Write Null/Nothing value with Databinding

    - by clawson
    I have extended a MaskedTextBox component to add some functionality. The text property of the extended MaskedTextBox is bound to a DateTime? property and the format of binding is set to a time format of "HH:mm:ss" (i.e. 24hr time). So that this masked text box will capture the display a time. The extra functionality I have added is to make the component readonly unless the component is double clicked or the enter button is pressed (the back color of the control helps to inform the users if the component is locked/readonly or not). When the enter button is pressed I also suspend the bindings so that bound data is updated the users input won't be lost. The information is then written back to the value and databindings resumed when the user presses the enter key again. This all works fine up to here, with values written and displayed as would be expected. However, I also want to write the null or nothing value to the DateTime? property if the user hasn't entered any text (or invalid text but let's just stick with no text) when enter key is pressed to submit the new value. Unlike with other valid entries in the MaskedTextBox, with no text entered when i execute: Me.DataBindings("Text").WriteValue() (when 'locking' the MaskedTextBox) it then branches to the bound properties Get method as I step into each line of code in the debugger (as opposed to the Set method with other valid entries) How can I write this null/nothing/"" value to the DateTime? property when no text "" is entered into the MaskedTextBox? Thanks for the help!
