• Is there a good digraph layout library callable from C++?

  - by Steve314

  The digraphs represent finite automata. Up until now my test program has been writing out dot files for testing. This is pretty good both for regression testing (keep the verified output files in subversion, ask it if there has been a change) and for visualisation. However, there are some problems... Basically, I want something callable from C++ and which plans a layout for my states and transitions but leaves the drawing to me - something that will allow me to draw things however I want and draw on GUI (wxWidgets) windows. I also want a license which will allow commercial use - I don't need that at present, and I may very well release as open source, but I don't want to limit my options ATM. The problems with GraphViz are (1) the warnings about building from source on Windows, (2) all the unnecessary dependencies for rendering and parsing, and (3) the (presumed) lack of a documented API specifically and purely for layout. Basically, I want to be able to specify my states (with bounding rectangle sizes) and transitions, and read out positions for the states and waypoints for each transition, then draw based on those co-ordinates myself. I haven't really figured out how annotations on transitions should be handled, but there should be some kind of provision for specifying bounding-box-sizes for those, associating them with transitions, and reading out positions. Does anyone know of a library that can handle those requirements? I'm not necessarily against implementing something for myself, but in this case I'd rather avoid it if possible.

• JQuery val() does not work for textarea in Opera

  - by Anil Soman

  I am displaying a modal dialog using jQuery. This dialog has a textarea control on it. But on submitting this dialog, the value of this textarea is not recognized by jQyery for some reason. It always comes blank. This works perfectly in other browsers. I put alert to display the value but it looks blank. Can anybody help me in this regards? Controls <input type="text" id="txtGroupName"/> <textarea rows="3" cols="30" id="txtDescription"></textarea> jQuery code which used this value var postData = new Object(); postData.GroupName = $('#txtGroupName').val(); postData.Description = $('#txtDescription').val(); $('#txtDescription').val() comes blank but $('#txtGroupName').val() is read correctly as it is a input field. One more finding about this issue: When I put alert in my update function after populating the control value on page load, this alert displays the existing value properly. But it displays only existing value. It does not display the edited value after submitting the modal box.

• How to create refresh statements for TableAdapter objects in Visual Studio?

  - by Mark Wilkins

  I am working on developing an ADO.NET data provider and an associated DDEX provider. I am unable to convince the Visual Studio TableAdapater Configuration Wizard to generate SQL statements to refresh the data table after inserts and updates. It generates the insert and delete statements but will not produce the select statements to do the refresh. The functionality referred to can be accessed by dropping a table from the Server Explorer (inside Visual Studio) onto a DataSet (e.g., DataSet1.xsd). It creates a TableAdapter object and configures SELECT, UPDATE, DELETE, and INSERT statements. If you right click on the TableAdapter object, the context menu has a “Configure” option that starts the “TableAdapter Configuration Wizard”. The first dialog of that wizard has an Advanced Options button, which leads to an option titled “Refresh the data table”. When used with SQL Server tables, that option causes a statement of the form “select field1, field2, …” to be added on to the end of the commands for the TableAdapter’s InsertCommand and UpdateCommand. Do you have any idea what type property or interface might need to be exposed from the DDEX provider (or maybe the ADO.NET data provider) in order to make Visual Studio add those refresh statements to the update/insert commands? The MSDN documentation for the Advanced SQL Generation Options Dialog Box has a note stating, “Refreshing the data table is only supported on databases that support batching of SQL statements.” This seems to imply that a .NET data provider might need to expose some property indicating such behavior is supported. But I cannot find it. Any ideas?

• ASP.NET DropDownList posting ""

  - by Daniel

  I am using ASP.NET forms version 3.5 in VB I have a dropdownlist that is filled with data from a DB with a list of countries The code for the dropdown list is <label class="ob_label"> <asp:DropDownList ID="lstCountry" runat="server" CssClass="ob_forminput"> </asp:DropDownList> Country*</label> And the code that the list is Dim selectSQL As String = "exec dbo.*******************" ' Define the ADO.NET objects. Dim con As New SqlConnection(connectionString) Dim cmd As New SqlCommand(selectSQL, con) Dim reader As SqlDataReader ' Try to open database and read information. Try con.Open() reader = cmd.ExecuteReader() ' For each item, add the author name to the displayed ' list box text, and store the unique ID in the Value property. Do While reader.Read() Dim newItem As New ListItem() newItem.Text = reader("AllSites_Countries_Name") newItem.Value = reader("AllSites_Countries_Id") CType(LoginViewCart.FindControl("lstCountry"), DropDownList).Items.Add(newItem) Loop reader.Close() CType(LoginViewCart.FindControl("lstCountry"), DropDownList).SelectedValue = 182 Catch Err As Exception Response.Redirect("~/error-on-page/") MailSender.SendMailMessage("*********************", "", "", OrangeBoxSiteId.SiteName & " Error Catcher", "<p>Error in sub FillCountry</p><p>Error on page:" & HttpContext.Current.Request.Url.AbsoluteUri & "</p><p>Error details: " & Err.Message & "</p>") Response.Redirect("~/error-on-page/") Finally con.Close() End Try When the form is submitted an error occurs which says that the string "" cannot be converted to the datatype integer. For some reason the dropdownlist is posting "" rather than the value for the selected country.

• Paramaterising SQL in SSIS

  - by Anonymouslemming

  Hi all, I'm trying to paramaterize some queries in SSIS. After some reading, it sounds like my best option is to create one variable that contains my base sql, another that contains my criteria and a final variable that is evaluated as an expression that includes both of these. I want to end up with an SQL query that is effectively UPDATE mytable set something='bar' where something_else='foo' So my first two variables have the scope of my package and are as follows: Name: BaseSQL Data Type: String Value: UPDATE mytable set something = 'bar' where something_else = Name: MyVariable Data Type: String Value: foo My third variable has a scope of the data flow task where I want to use this SQL and is as follows: Name: SQLQuery Data Type: String Value: @[User::BaseSQL] + "'" + @[User::MyVariable] + "'" EvaluateAsExpression: True In the OLE DB Source, I then choose my connection and 'SQL command from variable' and select User::SQLQuery from the dropdown box. The Variable Value window then displays the following: @[User::BaseSQL] + "'" + @[User::MyVariable] + "'" This is as desired, and would provide the output I want from my DB. The variable name dropdown also contains User::BaseSQL and User::MyVariable so I believe that my namespaces are correct. However, when I then click preview, I get the following error when configuring an OLE DB Source (using SQL command from variable): TITLE: Microsoft Visual Studio Error at Set runtime in DB [Set runtime in myDb DB [1]]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80040E14. An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80040E14 Description: "Statement(s) could not be prepared.". An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80040E14 Description: "Must declare the scalar variable "@".". (Microsoft Visual Studio) Can anyone advise what I'm missing or how I can resolve this please ? Thanks in advance!

• Can you recommend a full-text search engine?

  - by Jen

  Can you recommend a full-text search engine? (Preferably open source) I have a database of many (though relatively short) HTML documents. I want users to be able to search this database by entering one or more search words in my C++ desktop application. Hence, I’m looking for a fast full-text search solution to integrate with my app. Ideally, it should: Skip common words, such as the, of, and, etc. Support stemming, i.e. search for run also finds documents containing runner, running and ran. Be able to update its index in the background as new documents are added to the database. Be able to provide search word suggestions (like Google Suggest) Have a well-documented API To illustrate, assume the database has just two documents: Document 1: This is a test of text search. Document 2: Testing is fun. The following words should be in the index: fun, search, test, testing, text. If the user types t in the search box, I want the application to be able to suggest test, testing and text (Ideally, the application should be able to query the search engine for the 10 most common search words starting with t). A search for testing should return both documents. Other points: I don't need multi-user support I don't need support for complex queries The database resides on the user's computer, so the indexing should be performed locally. Can you suggest a C or C++ based solution? (I’ve briefly reviewed CLucene and Xapian, but I’m not sure if either will address my needs, especially querying the search word indexes for the suggest feature).

• asyncronous call doesn't return json

  - by Rebecca

  I am running wamp on an xp box. I am fairly new to web programming, this is for a student project, and have run out of avenues to try to solve this problem. Problem We have client side JavaScript code that uses GDownloadUrl- from the Google api- to wrap xmlHttpRequest calls to a php server side program that is accessing our database. In my callback program, the result of this call is always " ". However, if I use an alert to display the http:// call, with the arguments, and cut and paste that into my browser, the json I expected is displayed. I zipped my dir containing all the files, and tried it out on another team member's computer, and they were able to get the json in the callback function. Note this is exactly the same code and structure I was using, he just unzipped and ran. So now I'm thinking this is something about Firefox or Wamp? Would this be a config problem? I'm running wamp server 2.0, and Firefox 3.5.8. I have no problems with syncronous php, or reading in files asyncronously. Any help would be greatly appreciated. Rebecca

• DisplayObject snapshot in flex 3

  - by simplemagik

  i'm creating a visual editor in flex and need to let users export thier projects into Image format. But i have one problem: size of the canvas is fixed and when user add element which is out of these sizes some scroll bars added. And user continue working on the project. but when he want to take snapshot of the canvas he just get the visible part ot the canvas with scrollbars. how to get image of the fullsize canvas? The only solution i found is to check the positions and sizes of canvas child objects and rezise it to fit them. then take snap and resize back. But it hmmmm... too complicated i think. Is there some "easy methods"? <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"> <mx:Script> <![CDATA[ import mx.graphics.ImageSnapshot; private function SnapshotButtonHandler():void { var snapshot:ImageSnapshot = ImageSnapshot.captureImage(AppCanvas); var file:FileReference = new FileReference(); file.save(snapshot.data, "canvas.png"); } ]]> </mx:Script> <mx:Canvas id="AppCanvas" width="800" height="300" backgroundColor="0xFFFFFF"> <mx:Box x="750" y="100" width="100" height="100" backgroundColor="0xCCCCCC" /> </mx:Canvas> <mx:Button id="SnapshotButton" label="take snapshot" click="SnapshotButtonHandler()" /> </mx:Application>

• Django + Virtualenv: manage.py commands fail with ImportError of project name.

  - by Bartek

  This is blowing my mind because it's probably an easy solution, but I can't figure out what could be causing this. So I have a new dev box and am setting everything up. I installed virtualenv, created a new environment for my project under ~/.virtualenvs/projectname Then, I cloned my project from github into my projects directory. Nothing fancy here. There are no .pyc files sitting around so it's a clean slate of code. Then, I activated my virtualenv and installed Django via pip. All looks good so far. Then, I run python manage.py syncdb within my project dir. This is where I get confused: ImportError: No module named projectname So I figured I may have had some references of projectname within my code. So I grep (ack, actually) through my code base and I find nothing of the sorts. So now I'm at a loss, given this environment why am I getting an ImportError on a module named projectname that isn't referenced anywhere in my code? I look forward to a solution .. thanks guys!

• Javascript Rich Display Component/Methodology

  - by Laramie

  quick back story-- I am working on ASP.Net based template editor that lets authors create text templates using Javascript inserted placeholder tags that will be filled in with dynamic text when the templates are used to display the final results. For example the author might create a template like The word [%12#add] was generated dynamically. The application would eventually replace the tag with a dynamic word down the road (though it's not specifically relevant to this post) The word foo was generated dynmamically. Depending on the circumstances, the template may be created in a text input, textarea or a modified version of the Ajax Control Toolkit HTML Editor. There might be 40 or more of these editable elements on the page, so using lots of stripped down or modified HTML editors would probably bog the page down too much. The problem is that the tags such as [%12#add] are displayed inline with the user text and the result is confusing and aesthetically gross. The goal is parse the contens of the source element and when a tags such as [%12#add] are encountered, display something prettier and less cryptic to the user such as a stylable element or image wherever tags such as [%12#add] occur. The application still needs the template text with the tags on postback. So the user might see The word tag placeholder was generated dynamically. but the original template would still be the value of the text input box The word [%12#add] was generated dynamically. It seems HTML editors like the ACT version and FckEditor accomplish this by rendering their output in an IFrame, but rather than kill myself trying to roll a lighter specialized version myself, I thought I'd ask if anyone knows of an existing free component or approach that has already tackled this. With good reason, I don't think S.O. allows HTML formatting, but the bold "tag placeholder" above would ideally be something like tag placeholder.

• Cancel page forward/back hotkeys in Firefox with Greasemonkey

  - by Stimulating Pixels

  First the background: In Firefox 3.6.3 on Mac OS X 10.5.8 when entering text into a standard the hotkey combination of Command+LeftArrow and Command+RightArrow jump the cursor to the start/end of the current line, respectively. However, when using CKEditor, FCKEditor and YUI Editor, Firefox does not seem to completely recognize that it's a text area. Instead, it drops back to the default function for those hotkeys which is to move back/forward in the browser history. After this occurs, the text in the editor is also cleared when you return to the page making it very easy to loose whatever is being worked on. I'm attempting to write a greasemonkey script that I can use to capture the events and prevent the page forward/back jumps from being executed. So far, I've been able to see the events with the following used as a .user.js script in GreaseMonkey: document.addEventListener('keypress', function (evt) { // grab the meta key var isCmd = evt.metaKey; // check to see if it is pressed if(isCmd) { // if so, grab the key code; var kCode = evt.keyCode; if(kCode == 37 || kCode == 39) { alert(kCode); } } }, false ); When installed/enabled, pressing command+left|right arrow key pops an alert with the respective code, but as soon as the dialog box is closed, the browser executes the page forward/back move. I tried setting a new code with evt.keyCode = 0, but that didn't work. So, the question is, can this Greasemonkey script be updated so that it prevents the back/forward page moves? (NOTE: I'm open to other solutions as well. Doesn't have to be Greasemonkey, that's just the direction I've tried. The real goal is to be able to disable the forward/back hotkey functionality.)

• how to make sure the non disclosure agreement is read

  - by Xin Qian Ch'ang

  Every time a user registers to our site we need to show a non-disclosure agreement. In order to continue the user has to accept it. My issue is that I have the NDA in all one page and the user does not really read it and accept (like we all do). What I want is to make sure the user reads the NDA and accepts it one he "read" it? What I have now is a simple jqeury validation if the user checks a box and click on accept. then it goes to the next page. Here's what i have <script> $(document).ready(function() { $('#go').click(function() { // check if checkbox is check and go to next page }); }); </script> <div> full nda <hr> <input type=checkbox> <input type=button value=go id=go> </div> Thanks

• CheckBox won't toggle in Android ListView with focusable="false"

  - by user3563124

  I'm creating a ListView with a custom Adapter for displaying my entries. Each row contains a checkbox, and my adapter contains the following code: CheckBox cb = (CheckBox) v.findViewById(R.id.item_sold); cb.setChecked(p.isSold); setupCheckboxListener(cb, v, position); ... private void setupCheckboxListener(CheckBox check, final View v, final int position) { check.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { CheckBox cb = (CheckBox) v; if (cb.isChecked()) { System.out.println("Should become false!"); cb.setChecked(false); } else { System.out.println("Should become true!"); cb.setChecked(true); } } }); My row XML file includes the following: <CheckBox android:id="@+id/item_sold" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="0.10" android:layout_gravity="center" android:gravity="center" android:focusable="false" android:clickable="false"/> But anytime I press one of the checkboxes, check.isChecked() returns true, even if the box is unchecked. I even checked to make sure that the checkboxes were distinct and weren't picking up just the last value/etc. Setting up the listeners inline instead of in a method doesn't seem to help, either. It's literally just the isChecked() condition that isn't working appropriately - it seems to always give me the inverse value. Setting an onClick on the row is not acceptable in this case because I need to allow row selection for something else. What could be causing this issue?

• php insert doesnot take place

• 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?

• Java Client .class File Protection

  - by Zac

  I am in the requirements phase of building a JEE application that will most likely run on a GlassFish/JBoss backend (doesn't matter for now). I know I shouldn't be thinking about architecture at requirements time, but one can't help but start to imagine how the components would all snap together :-) Here are some hard, non-flexible requirements on the client-side: (1) The client application will be a Swing box (2) The client is free to download, but will use a subscription model (thus requiring a login mechanism with server-side authentication/authorization, etc.) (3) Yes, Java is the best platform solution for the problem at hand for reasons outside the scope of this post (4) The client-side .class files need safeguarding against decompiling That last (4th) requirement is the basis of this post. I'm not really worried about someone actually decompiling and getting at my source code: in the end, it's just Swing controls driven by some lightweight business logic. I'm worried about a scenario where someone decompiles my code, modifies it to exploit/attack the server, re-compiles, and fires it up. I've envisioned all sorts of nasty solutions, but didn't know if this was a common problem with a common solution for JEE developers. Any thoughts? Not interested in "code obfuscation" techniques! Thanks for any input!

• Is it possible to execute a function in Mongo that accepts any parameters?

  - by joshua.clayton

  I'm looking to write a function to do a custom query on a collection in Mongo. Problem is, I want to reuse that function. My thought was this (obviously contrived): var awesome = function(count) { return function() { return this.size == parseInt(count); }; } So then I could do something along the lines of: db.collection.find(awesome(5)); However, I get this error: error: { "$err" : "error on invocation of $where function: JS Error: ReferenceError: count is not defined nofile_b:1" } So, it looks like Mongo isn't honoring scope, but I'm really not sure why. Any insight would be appreciated. To go into more depth of what I'd like to do: A collection of documents has lat/lng values, and I want to find all documents within a concave or convex polygon. I have the function written but would ideally be able to reuse the function, so I want to pass in an array of points composing my polygon to the function I execute on Mongo's end. I've looked at Mongo's geospatial querying and it currently on supports circle and box queries - I need something more complex.

• Google Calendar like interface

  - by John Virgolino

  I need to write an application that essentially functions like a week-view of a calendar, columns for the days and then rows for appointments. Where the height of the appointment box visually represents time. In my case, I just don't want the time of day as the vertical axis, I just want hours or mins. The Google AJAX approach is very clean and easy to use and would be perfect, I think, but my major knowledge comes in ASP.Net and Windows Forms (.Net). I don't want to reinvent the wheel, but I find my mind is stuck on this problem and that I would have to create an interface from scratch for this. I have checked out the Infragistics product (used it for other projects) and read up a lot on the Google API's including their Ajax toolkit. I haven't done Java, however learning a language is not my issue, it's learning the particulars that will help me reach my goal that I feel will take most of the time. Am I making a mountain out of a mole hill? Is this really a lot easier than I think? This is starting to sound like a Dear Abby post - I'll stop now. Any advice or insight would be great! Thanks all!

• Bizarre problem with WPF XAML file.

  - by paxdiablo

  I've just started a very simple WPF application which consists of a main large image and four smaller images. In order to assist with the layout, I created some JPEGs in MsPaint containing the images -2, -1, 0, +1 and +2 and just copied them into the top level of the project directory. The XAML segment contains, for the five images: <Image Grid.Column="1" Grid.Row="2" Grid.ColumnSpan="4" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicture" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/zero.jpg" <Image Grid.Column="1" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicMinus2" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/minus2.jpg" <Image Grid.Column="2" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicMinus1" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/minus1.jpg" <Image Grid.Column="3" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicPlus1" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/plus1.jpg" <Image Grid.Column="4" Grid.Row="4" Grid.ColumnSpan="1" Grid.RowSpan="1" Margin="0,0,0,0" Name="imgPicPlus2" Stretch="Fill" VerticalAlignment="Top" Source="file:///C:/DAndS/Pax/MyDocs/VS2008/Projects/MyProj/plus2.jpg" When I try to set the source property for the plus2 image, it complains with a dialog box stating: Property value is not valid. Details | V The file plus2.jpg is not part of the project or its 'Build Action' property is not set to 'Resource'. Yet if I rename the file to plus3.jpg or plus2x.jpg, I don't have that problem. Why is it complaining about plus2.jpg specifically?

• Dynamically add columns to a listbox

  - by mgroves

  I'm brand new to Windows Phone 7 development, and almost as equally new to Silverlight. I have a ListBox with a DataTemplate, StackPanel, and TextBlocks like so: <ListBox Height="355" HorizontalAlignment="Left" Margin="6,291,0,0" Name="detailsList" VerticalAlignment="Top" Width="474" Background="#36FFFFFF"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Width="50" Text="{Binding Ticker}" /> <TextBlock Width="50" Text="{Binding Price}" /> <TextBlock Width="50" Text="{Binding GainLoss}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> I have some C# code to populate it: var info = new List<StockInfo>(); info.Add(new StockInfo { Ticker = "C", Price = "5.18", GainLoss = "10" }); info.Add(new StockInfo { Ticker = "WEN", Price = "4.18", GainLoss = "12" }); info.Add(new StockInfo { Ticker = "CBB", Price = "5.22", GainLoss = "210" }); detailsList.ItemsSource = info; And that all works fine. My question is: how do I add/remove additional 'textblocks' to the listbox dynamically (at runtime)? Also, how do I put column headers on the list box?

  Imagine I have a rectangle say 400px x 300px. Then let’s say I want to load an image in that. All of this is very easy using Sytem.Drawing.DrawImage. But then I want to leave the left hand side as 300px but change the right hand side to 250 px. I can draw the box using 4 DrawLines but I don’t know how to squash the image into the new shape. I want the right hand side of the shape to be 250, the left size 300 and the top and bottom 400px. I can’t use DrawImage as it expects the left and right sizes to be the same. Is there a way to manipulate the image into the new shape? I've looked at other questions, but they only apply where the left and right hand side is equal. Any thoughts on how to squash an image into a shape which did not have parallel sides? (If it helps, I'm happy to sacrifice image quality to fit the right shape.)

• How do I get rid of these warnings?

  - by Brian Postow

  This is really several questions, but anyway... I'm working with a big project in XCode, relatively recently ported from MetroWorks (Yes, really) and there's a bunch of warnings that I want to get rid of. Every so often an IMPORTANT warning comes up, but I never look at them because there's too many garbage ones. So, if I can either figure out how to get XCode to stop giving the warning, or actually fix the problem, that would be great. Here are the warnings: It claims that <map.h> is antiquated. However, when I replace it with <map> my files don't compile. Evidently, there's something in map.h that isn't in map... this decimal constant is unsigned only in ISO C90 This is a large number being compared to an unsigned long. I have even cast it, with no effect. enumeral mismatch in conditional expression: <anonymous enum> vs <anonymous enum> This appears to be from a ?: operator. Possibly that the then and else branches don't evaluate to the same type? Except that in at least one case, it's (matchVp == NULL ? noErr : dupFNErr) And since those are both of type OSErr, which is mac defined... I'm not sure what's up. It also seems to come up when I have other pairs of mac constants... multi-character character constant This one is obvious. The problem is that I actually NEED multi-character constants... -fwritable-strings not compatible with literal CF/NSString I unchecked the "Strings are Read-Only" box in both the project and target settings... and it seems to have had no effect...

• How do I create a python module from a fortran program with f2py?

  - by Lars Hellemo

  I am trying to read some smps files with python, and found a fortran implementation, so I thought I would give f2py a shot. The problem is that I have no experience with fortran. I have successfully installed gfortran and f2py on my Linux box and ran the example on thew f2py page, but I have some trouble compiling and running the large program. There are two files, one with a file reader wrapper and one with all the logic. They seem to call each other, but when I compile and link or try f2py, I get errors that they somehow can't find each other: f95 -c FILEWR~1.F f95 -c SMPSREAD.F90 f95 -o smpsread SMPSREAD.o FILEWR~1.o FILEWR~1.o In function `file_wrapper_' FILEWR~1.F(.text+0x3d) undefined reference to `chopen_' usrlibgcci486-linux-gnu4.4.1libgfortranbegin.a(fmain.o) In function `main' (.text+0x27) undefined reference to `MAIN__' collect2 ld returned 1 exit status I also tried changing the name to FILE_WRAPPER.F but that did not help. With f2py I found out I had to include a comment to get it to accept free format, and saved this as a new file and tried: f2py -c -m smpsread smpsread.f90 I get a lot of output and warnings, but the error seems to be this one: getctype: No C-type found in "{'typespec': 'type', 'attrspec': ['allocatable'], 'typename': 'node', 'dimension': [':']}", assuming void. The fortran 90 spms reader can be found here. Any help or suggestions appreciated.

• PPR in tr:selectOneChoice does not work

  - by Nhut Le

  Hi, I have a simple testing page that test my PPR on a selectOneChoice component. when select a value from selectOnechoice 1, the selected value will display on a output label and also reset the selected value and the other selectOneChoice. However, it prints the selected values to the label correctly but it can't set the selected value for the other selectOneChoice. and Here are my page and my value change event method. <tr:form id="nhutForm"> <tr:selectOneChoice id="one" value="#{nhutTestBean.one}" autoSubmit="true" immediate="true" valueChangeListener="#{nhutTestBean.onMyValueChanged}"> <tr:selectItem label="0" value="0"/> <tr:selectItem label="1" value="1"/> <tr:selectItem label="2" value="2"/> <tr:selectItem label="3" value="3"/> </tr:selectOneChoice> <tr:selectOneChoice id="two" value="#{nhutTestBean.two}" partialTriggers="one"> <f:selectItems value="#{nhutTestBean.myList}"/> </tr:selectOneChoice> <tr:outputText id="nhutTextBox" value="hello: #{nhutTestBean.output}" partialTriggers="one"/></tr:form> and my valueChangeEvent method: public void onMyValueChanged(ValueChangeEvent event) { this.setOutput((String)event.getNewValue()); this.setTwo((String)event.getNewValue()); } One thing I realize is that it calls my setTwo twice, the first the set the correct values, but the second time set it to null so that nothing would be selected for the two drop down box. please help. thank you so much.
