• Java: library that does nice formatted log outputs

  - by WizardOfOdds

  I cannot find back a library that allowed to format log output statements in a much nicer way than what is usually seen. One of the feature I remember is that it could 'offset' the log message depending on the 'nestedness' of where the log statement was occuring. That is, instead of this: DEBUG | DefaultBeanDefinitionDocumentReader.java| 86 | Loading bean definitions DEBUG | AbstractAutowireCapableBeanFactory.java| 411 | Finished creating instance of bean 'MS-SQL' DEBUG | DefaultSingletonBeanRegistry.java| 213 | Creating shared instance of singleton bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java| 383 | Creating instance of bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java| 459 | Eagerly caching bean 'MySQL' to allow for resolving potential circular references DEBUG | AutowireCapableBeanFactory.java| 789 | Another debug message It would shows something like this: DEBUG | DefaultBeanDefinitionDocumentReader.java| 86 | Loading bean definitions DEBUG | AbstractAutowireCapableBeanFactory.java | 411 | Finished creating instance of bean 'MS-SQL' DEBUG | DefaultSingletonBeanRegistry.java | 213 | Creating shared instance of singleton bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java | 383 | Creating instance of bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java | 459 | |__ Eagerly caching bean 'MySQL' to allow for resolving potential circular references DEBUG | AutowireCapableBeanFactory.java | 789 | |__ Another debug message This is an example I just made up (VeryLongCamelCaseClassNamesNotMine). But I remember seeing such cleanly formatted log output and they were really much nicer than anything I had seen before and, in addition to being just plain nicer, they were also easier to read for they reproduced some of the logical organization of the code. Yet I cannot find anymore what that library was. I'm pretty sure it was fully compatible with log4j or sl4j.

• Linq: Why won't Group By work when Querying DataSets?

  - by jrcs3

  While playing with Linq Group By statements using both DataSet and Linq-to-Sql DataContext, I get different results with the following VB.NET 10 code: #If IS_DS = True Then Dim myData = VbDataUtil.getOrdersDS #Else Dim myData = VbDataUtil.GetNwDataContext #End If Dim MyList = From o In myData.Orders Join od In myData.Order_Details On o.OrderID Equals od.OrderID Join e In myData.Employees On o.EmployeeID Equals e.EmployeeID Group By FullOrder = New With { .OrderId = od.OrderID, .EmployeeName = (e.FirstName & " " & e.LastName), .ShipCountry = o.ShipCountry, .OrderDate = o.OrderDate } _ Into Amount = Sum(od.Quantity * od.UnitPrice) Where FullOrder.ShipCountry = "Venezuela" Order By FullOrder.OrderId Select FullOrder.OrderId, FullOrder.OrderDate, FullOrder.EmployeeName, Amount For Each x In MyList Console.WriteLine( String.Format( "{0}; {1:d}; {2}: {3:c}", x.OrderId, x.OrderDate, x.EmployeeName, x.Amount)) Next With Linq2SQL, the grouping works properly, however, the DataSet code doesn't group properly. Here are the functions that I call to create the DataSet and Linq-to-Sql DataContext Public Shared Function getOrdersDS() As NorthwindDS Dim ds As New NorthwindDS Dim ota As New OrdersTableAdapter ota.Fill(ds.Orders) Dim otda As New Order_DetailsTableAdapter otda.Fill(ds.Order_Details) Dim eda As New EmployeesTableAdapter eda.Fill(ds.Employees) Return ds End Function Public Shared Function GetNwDataContext() As NorthwindL2SDataContext Dim s As New My.MySettings Return New NorthwindL2SDataContext(s.NorthwindConnectionString) End Function What am I missing? If it should work, how do I make it work, if it can't work, why not (what interface isn't implemented, etc)?

• Modify post data with a custom MVC extension?

  - by Jaxidian

  So I'm looking into writing some custom MVC extensions and the first one I'm attempting to tackle is a FormattedTextBox to handle things such as currency, dates, and times. I have the rendering of it working perfectly, formatting it, working with strong types and everything all golden. However, the problem I'm now running into is cleaning up the formatted stuff when the page posts the data back. Take for example, a currency format. Let's use USD for these examples. When an object has a property as a decimal, the value would be 79.95. Your edit view would be something like: <%= Html.FormattedTextBox(model => Model.Person.HourlyWage, "{0:C}") %> This is all well and good for the GET request, but upon POST, the value is going to be $79.95, which when you assign to that decimal, gets unhappy very quickly and ends up shoving a 0 in there. So my question is, how do I get code working somewhere to work with that value before the MVC Framework goes and starts shoving it back into my ViewModel? I'd much rather this be done server-side than client-side. Thanks!!

• Foreach loop returning null values in PHP?

  - by Jascha

  Hello, I have a pretty simple problem. Basically I have an array called $list that is a list of titles. If I do a print_r($list) I get these results: Array ( [0] => Another New Title [1] => Awesome Movies and stuff [2] => Jascha's Title ) Now, I'm running a foreach loop to retrieve their values and format them in an <ul> like so... function get_film_list(){ global $categories; $list = $categories->get_film_list(); if(count($list)==0){ echo 'No films are in this category'; }else{ echo '<ul>'; foreach($list as $title){ echo '<li>' . $title . '<li>'; } echo '</ul>'; } } The problem I'm having is my loop is returning two values per value (is it the key value?) The result of the preceding function looks like this: Another New Title   Awesome Movies and stuff   Jascha's Title   I even tried: foreach($list as $key => $title){ echo '<li>' . $title . '<li>'; } With the same results: Another New Title   Awesome Movies and stuff   Jascha's Title   What am I missing here? Thanks in advance.

• How to make a WPF ComboBox editable with custom values

  - by Liam

  I would like to have a combobox that allows selection from a list of values and also allow a custom value from the typed in text. For display reasons the items are a complex type (lets say the combobox item template displays a patch of color and a flag indicating if it is a custom color). public class ColorLevel { public decimal Intensity { get; set; } public bool IsCustom { get; set; } public Color BaseColor { get; set; } public override ToString() { return string.Format("{0}", Intensity*100); } } Example items var items = new [] { new ColorLevel { Intensity = 0.9m, IsCustom = false, BaseColor = Color.Red }, new ColorLevel { Intensity = 0.7m, IsCustom = false, BaseColor = Color.Red } } XAML <ComboBox SelectedItem="{Binding Path=SelectedColorLevel}" IsEditable="true" IsTextSearchEnabled="true"> </ComboBox> So the above markup works when an item is selected from the item list. And as you type with the text search the matching items are selected. If the typed text doesn't match an item then the SelectedColorLevel is set to null. The question is at what point (and how) is it best to create a new custom item that can be set to the SelectedColorLevel when the typed text doesn't match an item. For example I would want to assign a new item to the selected value such as new ColorLevel { Intensity = decimal.Parse(textvalue), IsCustom = true } or using an appropriate converter and databinding to the Text property.

• PHP templating challenge (optimizing front-end templates)

  - by Matt

  Hey all, I'm trying to do some templating optimizations and I'm wondering if it is possible to do something like this: function table_with_lowercase($data) { $out = '<table>'; for ($i=0; $i < 3; $i++) { $out .= '<tr><td>'; $out .= strtolower($data); $out .= '</td></tr>'; } $out .= "</table>"; return $out; } NOTE: You do not know what $data is when you run this function. Results in: <table> <tr><td><?php echo strtolower($data) ?></td></tr> <tr><td><?php echo strtolower($data) ?></td></tr> <tr><td><?php echo strtolower($data) ?></td></tr> </table> General Case: Anything that can be evaluated (compiled) will be. Any time there is an unknown variable, the variable and the functions enclosing it, will be output in a string format. Here's one more example: function capitalize($str) { return ucwords(strtolower($str)); } If $str is "HI ALL" then the output is: Hi All If $str is unknown then the output is: <?php echo ucwords(strtolower($str)); ?> In this case it would be easier to just call the function (ie. <?php echo capitalize($str) ?> ), but the example before would allow you to precompile your PHP to make it more efficient

• google maps not working anymore at the drop of a hat

  - by Vordreller

  2 days ago, I was working on a project that involves google maps. The website showed the maps on the pages just fine. Now, I come back to my workstation, nothing has changed, expect for the fact that the google maps won't show up anymore. The code is identical, nobody has touched my machine since I was gone, I've checked the html, everything is perfect and still this isn't working... The Javascript console is giving no errors and the code is identical to a backup I make everytime I call it a day. 2 days ago it was working, today it isn't. I've even copied the source code, put it into an html file and tried that, but the same result. I'm at a loss here. This is my code: <script type="text/javascript"> //<![CDATA[ var map; var directionsPanel; var directions; function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("map")); map.addControl(new GLargeMapControl()); map.addControl(new GScaleControl()); map.addControl(new GMapTypeControl()); //the route description directionsPanel = document.getElementById("route"); directions = new GDirections(map, directionsPanel); directions.load({COMMAND}); } } //]]> </script> The {COMMAND} is something that the PHP template will parse, I've checked it, the format is 100% correct and like I allready said, code now is identical to the backup, and if it worked back then, it should work now. Did google update their API overnight and did a function that I use here become deprecated? I don't know what's going on here...

• Optimizing C# code in MVC controller

  - by cc0

  I am making a number of distinct controllers, one relating to each stored procedure in a database. These are only used to read data and making them available in JSON format for javascripts. My code so far looks like this, and I'm wondering if I have missed any opportunities to re-use code, maybe make some help classes. I have way too little experience doing OOP, so any help and suggestions here would be really appreciated. Here is my generalized code so far (tested and works); using System; using System.Configuration; using System.Web.Mvc; using System.Data; using System.Text; using System.Data.SqlClient; using Prototype.Models; namespace Prototype.Controllers { public class NameOfStoredProcedureController : Controller { char[] lastComma = { ',' }; String oldChar = "\""; String newChar = "&quot;"; StringBuilder json = new StringBuilder(); private String strCon = ConfigurationManager.ConnectionStrings["SomeConnectionString"].ConnectionString; private SqlConnection con; public StoredProcedureController() { con = new SqlConnection(strCon); } public string do_NameOfStoredProcedure(int parameter) { con.Open(); using (SqlCommand cmd = new SqlCommand("NameOfStoredProcedure", con)) { cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.AddWithValue("@parameter", parameter); using (SqlDataReader reader = cmd.ExecuteReader()) { while (reader.Read()) { json.AppendFormat("[{0},\"{1}\"],", reader["column1"], reader["column2"]); } } con.Close(); } if (json.Length.ToString().Equals("0")) { return "[]"; } else { return "[" + json.ToString().TrimEnd(lastComma) + "]"; } } //http://host.com/NameOfStoredProcedure?parameter=value public ActionResult Index(int parameter) { return new ContentResult { ContentType = "application/json", Content = do_NameOfStoredProcedure(parameter) }; } } }

• ComDlg32.ocx Error: Object doesn't support this property or method

  - by abhilashca

  I'm developing an html editor using ComDlg32.ocx (Commom Dialog Control), using HTML and VBScript. My exact requirement was to prompt Open/Save/Color/Print/Font dialog boxes.Ive written code for prompting Save file dialog box. Also I've added a license file using LPK Tool onto my webpage. My html-source looks like: <body> <!-- lpk file --> <object classid="clsid:5220cb21-c88d-11cf-b347-00aa00a28331"> <param name="LPKPath" value="License/comdlg.lpk" /> </object> <!-- Microsoft Common Dialog Control --> <object classid="CLSID:F9043C85-F6F2-101A-A3C9-08002B2F49FB" codebase="http://activex.microsoft.com/controls/vb6/COMDLG32.CAB" id="objComDlg"></object> </body> Now, here comes my error. Whenever I try to call the vbscript for prompting the Save File dialog box, Im getting an error as : Object doesn't support this property or method: 'objComDlg.Filter' If I comment out the objComDlg.Filter then the error move on to objComDlg.DialogTitle and thus it goes on. And my VBScript look like: FILE_FORMATS = "Rich Text Format (*.rtf)|*.rtf|Microsoft Word (*.doc)|*.doc|ANSI Text Document (*.txt)|*.txt" objComDlg.Filter = FILE_FORMATS <--- Error shows here objComDlg.DialogTitle = "Save As " objComDlg.Flags = cdlOFNFileMustExist Or cdlOFNHideReadOnly objComDlg.CancelError = True objComDlg.ShowSave Does anyone have an idea why this is happening? Is there any proper documentation for using this particular ActiveX control? My current development is in stand-still due to this error. Any help will be appreciated. Looking forward for your response. BTW, I'm using Windows XP SP3 and IE8 for my development. Thanks.

• Mac vs. Windows Browser Font Height Rendering Issue

  - by cdmckay

  I'm using a custom font and the @font-face tag. In Windows, everything looks great, regardless of whether it's Firefox, Chrome, or IE. On Mac, it's a different story. For some reason, the Mac font renderer thinks the font is a lot shorter than it is. For example, consider this test code (live example here): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Webble</title> <style type="text/css"> @font-face { font-family: "Bubbleboy 2"; src: url("bubbleboy-2.ttf") format('truetype'); } body { font-family: "Bubbleboy 2"; font-size: 30px; } div { background-color: maroon; color: yellow; height: 100px; line-height: 100px; } </style> </head> <body> <div>The quick brown fox jumped over the lazy dog.</div> </body> </html> Open it on Windows Firefox and on Mac Firefox. Use your mouse to select it. On Windows, you'll notice it fully selects the font. On Mac, it only selects about half the font. If you look at what it is selecting, you'll see that that part has been centered, instead of the full height of the font. Is there anyway to fix this rather large discrepancy?

• How do I build a JSON object to send to an AJAX WebService?

  - by Ben McCormack

  After trying to format my JSON data by hand in javascript and failing miserably, I realized there's probably a better way. Here's what the code for the web service method and relevant classes looks like in C#: [WebMethod] public Response ValidateAddress(Request request) { return new test_AddressValidation().GenerateResponse( test_AddressValidation.ResponseType.Ambiguous); } ... public class Request { public Address Address; } public class Address { public string Address1; public string Address2; public string City; public string State; public string Zip; public AddressClassification AddressClassification; } public class AddressClassification { public int Code; public string Description; } The web service works great with using SOAP/XML, but I can't seem to get a valid response using javascript and jQuery because the message I get back from the server has a problem with my hand-coded JSON. I can't use the jQuery getJSON function because the request requires HTTP POST, so I'm using the lower-level ajax function instead: $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "http://bmccorm-xp/HBUpsAddressValidation/AddressValidation.asmx/ValidateAddress", data: "{\"Address\":{\"Address1\":\"123 Main Street\",\"Address2\":null,\"City\":\"New York\",\"State\":\"NY\",\"Zip\":\"10000\",\"AddressClassification\":null}}", dataType: "json", success: function(response){ alert(response); } }) The ajax function is submitting everything specified in data:, which is where my problem is. How do I build a properly formatted JSON object in javascript so I can plug it in to my ajax call like so: data: theRequest I'll eventually be pulling data out of text inputs in forms, but for now hard-coded test data is fine. How do I build a properly formatted JSON object to send to the web service?

• How can I write an XSLT that will recursively include other files?

  - by Eric

  Let's say I have a series of xml files in this format: A.xml: <page> <header>Page A</header> <content>blAh blAh blAh</content> </page> B.xml: <page also-include="A.xml"> <header>Page B</header> <content>Blah Blah Blah</content> </page> Using this XSLT: <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="/page"> <h1> <xsl:value-of select="header" /> </h1> <p> <xsl:value-of select="content" /> </p> </xsl:template> </xsl:stylesheet> I can turn A.xml into this: <h1> Page A </h1> <p> blAh blAh blAh </p> But how would I make it also turn B.xml into this? <h1> Page B </h1> <p> Blah Blah Blah </p> <p> blAh blAh blAh </p> I know that I need to use document(concat(@also-include,'.xml')) somewhere, but I'm not sure where. Oh, and the catch is, I need this to still work if B were to be included in a third file, C.xml. Any idea as to how to do this?

• File Storage for Web Applications: Filesystem vs DB vs NoSQL engines

  - by El Yobo

  I have a web application that stores a lot of user generated files. Currently these are all stored on the server filesystem, which has several downsides for me. When we move "folders" (as defined by our application) we also have to move the files on disk (although this is more due to strange design decisions on the part of the original developers than a requirement of storing things on the filesystem). It's hard to write tests for file system actions; I have a mock filesystem class that logs actions like move, delete etc, without performing them, which more or less does the job, but I don't have 100% confidence in the tests. I will be adding some other jobs which need to access the files from other service to perform additional tasks (e.g. indexing in Solr, generating thumbnails, movie format conversion), so I need to get at the files remotely. Doing this over network shares seems dodgy... Dealing with permissions on the filesystem as sometimes given us problems in the past, although now that we've moved to a pure Linux environment this should be less of an issue. What are the downsides of storing files as BLOBs in MySQL? I guess that it would massively increase the database size and reduce the effectiveness of caches, but are there other problems? Do the same problems exist with NoSQL systems like Cassandra? Does anyone have any other suggestions that might be appropriate?

• String Manipulation: Splitting Delimitted Data

  - by Milli Szabo

  I need to split some info from a asterisk delimitted data. Data Format: NAME*ADRESS LINE1*ADDRESS LINE2 Rules: 1. Name should be always present 2. Address Line 1 and 2 might not be 3. There should be always three asterisks. Samples: MR JONES A ORTEGA*ADDRESS 1*ADDRESS2* Name: MR JONES A ORTEGA Address Line1: ADDRESS 1 Address Line2: ADDRESS 2 A PAUL*ADDR1** Name: A PAUL Address Line1: ADDR1 Address Line2: Not Given My algo is: 1. Iterate through the characters in the line 2. Store all chars in a temp variables until first * is found. Reject the data if no char is found before first occurence of asterisk. If some chars found, use it as the name. 3. Same as step 2 for finding address line 1 and 2 except that this won't reject the data if no char is found My algo looks ugly. The code looks uglier. Spliting using //* doesn't work either since name can be replaced with address line 1 if the data was *Address 1*Address2. Any suggestion?

• Generating PDF document using XSLT

  - by Nair

  I have one huge XML document. I have set of XSL representing each node in the XML. These XSL also have java script to generate the dynamic content. It uses images which are in seperate images folder and it uses fonts as well. At present, I have a program which displays all the nodes that can be transformed and user click on one of the node and the program performs XSLT and display the content in HTML format on IE screen. I want to write a program (.Net , C# or any .Net language) which will allow user to do XSLT tranform on all the available notes and create one PDF document. My initial requirement was to display all the document in the IE itself, so I reused the existing code, and foreach node, perform XSLT and then append it to the current HTML with a page break and it worked ok till we hit huge files. So the requirement changed to create one PDF file with all the nodes. I have couple of questions, 1. What is the best way to create PDF file using XSLT transformation? 2. Since the images are relative path, if we generate the XSLT in html and then write it to a output stream will it loose the images? 3. Will the font be preserved in the PDF document? Really appriciate if someone could point me to some good example that I can take and run with it. Thanks a lot.

• ListView Parsing Persian xml

  - by Namikaze Minato

  I used a tutorial about listview parsing xm from internet and using LasyAdapter shows the items in listview. When I add persian characters in xml (into one of childnodes) the result is some boxes in listview (after showing the text in listview). The format of xml is UTF-8, too. I used typeface too (but didn't work). Besides when I type Pwesian into the application it shows alright but it can't show Persiann content parsed from xml. Thanks in advance. I updated the post with original XMLparser (which was the problem). public String getXmlFromUrl(String url) { String xml = null; try { // defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); xml = EntityUtils.toString(httpEntity); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } // return XML return xml; } public Document getDomElement(String xml) { Document doc = null; DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); try { DocumentBuilder db = dbf.newDocumentBuilder(); InputSource is = new InputSource(); is.setCharacterStream(new StringReader(xml)); doc = db.parse(is); } catch (ParserConfigurationException e) { Log.e("Error: ", e.getMessage()); return null; } catch (SAXException e) { Log.e("Error: ", e.getMessage()); return null; } catch (IOException e) { Log.e("Error: ", e.getMessage()); return null; } return doc; }

• How to handle error with content-disposition

  - by František Žiacik

  Hi, how should I handle an exception that occurs after sending a Content-Disposition header for an attachment? I'm trying to generate a report at server and send it as a file, but if an exception occurs during the report generation, the error message itself is sent to browser which still takes it as a content of a file and shows a Save As dialog. User cannot know there was an error generating report, saves the file which is in wrong format now. Is there a way to cancel the response with this header and redirect to an error page? Or what else can I do to inform user about the error? Probably I could generate the report first and only if there was no error send the headers, but I want the report render directly to the Response output stream so that it does not need to stay in memory. Here is my code: this.Response.ContentType = "application/octet-stream"; this.Response.AddHeader("Content-Disposition", @"attachment; filename=""" + item.Name + @""""); this.Response.Flush(); GenerateReportTo(this.Response.OutputStream); // Exception occurs Thanks for any suggestions

• Vertically Merge Multiple Tables in MySQL by Joint Primary Key

  - by world

  Hello, I'll attempt to make my question as clear as possible. I'm fairly unexperienced with SQL, only know the really basic queries. In order to have a better idea I'd been reading the MySQL manual for the past few days, but I couldn't really find a concrete solution and my needs are quite specific. I've got 3 MySQL MyISAM tables: table1, table2 and table3. Each table has an ID column (ID, ID2, ID3 respectively), and different data columns. For example table1 has [ID, Name, Birthday, Status, ...] columns, table2 has [ID2, Country, Zip, ...], table3 has [ID3, Source, Phone, ...] you get the idea. The ID, ID2, ID3 columns are common to all three tables... if there's an ID value in table1 it will also appear in table2 and table3. The number of rows in these tables is identical, about 10m rows in each table. What I'd like to do is create a new table that contains (most of) the columns of all three tables and merge them into it. The dates, for instance, must be converted because right now they're in VARCHAR YYYYMMDD format. Reading the MySQL manual I figured STR_TO_DATE() would do the job, but I don't know how to write the query itself in the first place so I have no idea how to integrate the date conversion. So basically, after I create the new table (which I do know how to do), how can I merge the three tables into it, integrating into the query the date conversion?

• % style macros not supported in some C++/CLI project property pages under VS2010?

  - by Dave Foster

  We're currently evaluating VS2010 and have upgraded our VS2008 C++/CLI project to the new .vcxproj format. I've noticed that a certain property we had set in the project settings did not get translated properly. Under Configuration Properties - Managed Resources - Resource Logical Name, we used to have (in VS2008) the setting: $(IntDir)\$(RootNamespace).$(InputName).resources which indicated that all .resx files were to compile into OurLib.SomeForm.resources inside of the assembly. (the Debug portion is dropped when assembled) According to MSDN, the $(InputName) macro no longer exists and should be replaced with %(Filename). However, when translating the above line to swap those macros, it does not seem to ever expand. The second .resx file it tries to compile, I get a "LINK : fatal error LNK1316: duplicate managed resource name 'Debug\OurLib.%(Filename).resources". This indicates to me that the % style macros are not being expanded here, at least in this specific property. If we don't set anything in that property, the default behavior seems to be to add the subdirectory as a prefix, such as: OurLib.Forms.SomeForm.resources where Forms is the subdir of our project that the .resx file lives. This only occurs when the .resx file is in an immediate subdirectory of the project being built. If a .resx file exists somewhere else on disk (aka ..\OtherLib\Forms\SomeForm2.resx) this prefix is NOT added. This is causing an issue with loading form resources, as it does not account for this possible prefix, even though we are using the standard Forms Designer method of getting at resources: System::ComponentModel::ComponentResourceManager^ resources = (gcnew System::ComponentModel::ComponentResourceManager(SomeForm::typeid)); and do not specify the .resources file by name. The issue I've just described may not be the same as the original question, but if I were to fix the Resource Logical Name issue I think this would all go away. Does anyone have any information about these % macros and where they are allowed to be used?

• Oracle command hangs when using view for "WHILE x IN..." subquery

  - by Calvin Fisher

  I'm working on a web service that fetches data from an oracle data source in chunks and passes it back to an indexing/search tool in XML format. I'm the C#/.NET guy, and am kind of fuzzy on parts of Oracle. Our Oracle team gave us the following script to run, and it works well: SELECT ROWID, [columns] FROM [table] WHERE ROWID IN ( SELECT ROWID FROM ( SELECT ROWID FROM [table] WHERE ROWID > '[previous_batch_last_rowid]' ORDER BY ROWID ) WHERE ROWNUM <= 10000 ) ORDER BY ROWID 10,000 rows is an arbitrary but reasonable chunk size and ROWID is sufficiently unique for our purposes to use as a UID since each indexing run hits only one table at a time. Bracketed values are filled in programmatically by the web service. Now we're going to start adding views to the indexing, each of which will union a few separate tables. Since ROWID would no longer function as a unique identifier, they added a column to the views (VIEW_UNIQUE_ID) that concatenates the ROWIDs from the component tables to construct a UID for each union. But this script does not work, even though it follows the same form as the previous one: SELECT VIEW_UNIQUE_ID, [columns] FROM [view] WHERE VIEW_UNIQUE_ID IN ( SELECT VIEW_UNIQUE_ID FROM ( SELECT VIEW_UNIQUE_ID FROM [view] WHERE ROWID > '[previous_batch_last_view_unique_id]' ORDER BY VIEW_UNIQUE_ID ) WHERE ROWNUM <= 10000 ) ORDER BY VIEW_UNIQUE_ID It hangs indefinitely with no response from the Oracle server. I've waited 20+ minutes and the SQLTools dialog box indicating a running query remains the same, with no progress or updates. I've tested each subquery independently and each works fine and takes a very short amount of time (<= 1 second), so the view itself is sound. But as soon as the inner two SELECT queries are added with "WHERE VIEW_UNIQUE_ID IN...", it hangs. Why doesn't this query work for views? In what important way are they not interchangeable here?
