• FileUpload ASP.NET control not working under Windows 7

  - by YourMomzThaBomb

  I have a User Control that contains a System.Web.UI.WebControls.FileUpload control as well as a button to 'Submit'. When the button is clicked code similar to the following is executed: If FileUploadControl.HasFile Then 'Save the file and do some other stuff End If This code works just fine with Windows XP. However, if I run it from a Windows 7 64-bit machine using IE8 32-bit the HasFile property always returns false and nothing is saved?! Any suggestions/ideas would be greatly appreciated.

• IE6 Bug - Div within Anchor tag: inline images not links

  - by thorn100

  I'm trying to get everything in the anchor tag to be a clickable link. Unfortunately, in IE6 (which is the only browser I'm concerned with currently), the only thing that isn't a clickable link are the inline images. I know that it's not valid html to put a div inside of an anchor but it's not my markup and I've been asked to avoid changing it. Any suggestions to altering the CSS to enable the images as clickable links? If changing the markup is the only solution... any suggestions there? My initial thought was to set the image as a background of it's parent (.ph-item-featured-img), although I'm unclear if that will solve the problem. Thanks! <div class="tab-panel-init clear ui-tabs-panel ui-widget-content ui-corner-bottom" id="ph-flashlights"> <a href="#" class="last ph-item-featured clear"> <div class="ph-item-featured-img"> <img src="#"> &nbsp; </div> <strong> PRODUCT CODE </strong> <p> PRODUCT CODE Heavy Duty Aluminum Led Flashlight </p> <span>Learn more &gt;</span> </a> <a href="#" class="last ph-item-featured clear"> <div class="ph-item-featured-img"> <img src="#"> &nbsp; </div> <strong> PRODUCT CODE </strong> <p> PRODUCT CODE Heavy Duty Aluminum Led Flashlight </p> <span>Learn more &gt;</span> </a> </div>

• What defines writing PHP?

  - by cdburgess

  When writing PHP code for any given project, do you find you can write code off the top of your head? Or do you make multiple round trips to php.net? If it is the later, can you still be considered a good coder. This is a legitimate question as I find I have difficulty always remembering all of the functions that are available to me so I find I use php.net as a crutch. Is there anyway to improve this?

• C variable declarations after function heading in definition

  - by Yktula

  When reading some FreeBSD source code (See: radix.h lines 158-173), I found variable declarations that followed the "function heading" in the definition. Is this valid in ISO C (C99)? when should this be done in production code instead of just declaring the variables within the "function heading?" Why is it being done here? I refer to the function heading the string that looks like this: int someFunction(int i, int b) {

• Fairness: Where can it be better handled?

  - by Srinivas Nayak

  Hi, I would like to share one of my practical experience with multiprogramming here. Yesterday I had written a multiprogram. Modifications to sharable resources were put under critical sections protected by P(mutex) and V(mutex) and those critical section code were put in a common library. The library will be used by concurrent applications (of my own). I had three applications that will use the common code from library and do their stuff independently. my library --------- work_on_shared_resource { P(mutex) get_shared_resource work_with_it V(mutex) } --------- my application ----------- application1 { *[ work_on_shared_resource do_something_else_non_ctitical ] } application2 { *[ work_on_shared_resource do_something_else_non_ctitical ] } application3 { *[ work_on_shared_resource ] } *[...] denote a loop. ------------ I had to run the applications on Linux OS. I had a thought in my mind, hanging over years, that, OS shall schedule all the processes running under him with all fairness. In other words, it will give all the processes, their pie of resource-usage equally well. When first two applications were put to work, they run perfectly well without deadlock. But when the third application started running, always the third one got the resources, but since it is not doing anything in its non-critical region, it gets the shared resource more often when other tasks are doing something else. So the other two applications were found almost totally halted. When the third application got terminated forcefully, the previous two applications resumed their work as before. I think, this is a case of starvation, first two applications had to starve. Now how can we ensure fairness? Now I started believing that OS scheduler is innocent and blind. It depends upon who won the race; he got the largest pie of CPU and resource. Shall we attempt to ensure fairness of resource users in the critical-section code in library? Or shall we leave it up to the applications to ensure fairness by being liberal, not greedy? To my knowledge, adding code to ensure fairness to the common library shall be an overwhelming task. On the other hand, believing on the applications will also never ensure 100% fairness. The application which does a very little task after working with shared resources shall win the race where as the application which does heavy processing after their work with shared resources shall always starve. What is the best practice in this case? Where we ensure fairness and how? Sincerely, Srinivas Nayak

• How can I get the plain-text content of a Google Doc via Google Doc API in Silverlight?

  - by Edward Tanguay

  I would like to use the Google Doc API to retrieve the plain-text content of a Google Doc document (not a spreadsheet) via the Google Docs API. In the documentation I can find information about accessing Spreadsheets and how to "create/upload/copy" documents: http://code.google.com/apis/documents/overview.html Does anyone have a C# code example to do this in Silverlight, something like this: //PSEUDOCODE: WebClientGoogleDoc proxy = new WebClientGoogleDoc (); proxy.DownloadStringCompleted += new DownloadStringCompletedEventHandler(proxy_DownloadStringCompleted); proxy.DownloadProgressChanged += new DownloadProgressChangedEventHandler(proxy_DownloadProgressChanged); proxy.DownloadStringAsyncWithGoogleDocId("dc7gj86r_20dn2csqg3");

• How do you decide which API function documentations to read and how seriously?

  - by Uri

  Suppose that you are writing or maintaining a piece of code that uses some API that you are not 100% familiar with. How do you decide whether to read the documentation of a certain call target, and how much time to spend reading it? How do you decide not to read it? (Let's assume you can read it by opening the HTML documentation, inspecting the source code, or using the hover mechanism in the IDE).

• Custom UINavigationBar Background

  - by tigermain

  I've been trying to set up a custom background for the whole of my NavigationBar (not just the titleView) but have been struggling. I found this thread http://discussions.apple.com/thread.jspa?threadID=1649012&tstart=0 But am not sure how to implement the code snippet that is given. Is the code implemented as a new class? Also where do I instatiate the NavigationController as I have an application built with the NavigationView template so it is not done in my root controller as per the example

• How can I make Swig correctly wrap a char* buffer that is modified in C as a Java Something-or-other

  - by Ukko

  I am trying to wrap some legacy code for use in Java and I was quite happy to see that Swig was able to handle the header file and it generate a great wrapper that almost works. Now I am looking for the deep magic that will make it really work. In C I have a function that looks like this DLL_IMPORT int DustyVoodoo(char *buff, int len, char *curse); This integer returned by this function is an error code in case it fails. The arguments are buff is a character buffer len is the length of the data in the buffer curse the another character buffer that contains the result of calling DustyVoodoo So, you can see where this is going, the result is actually coming back via the third argument. Also len is confusing since it may be the length of both buffers, they are always allocated as being the same size in calling code but given what DustyVoodoo does I don't think that they need be the same. To be safe both buffers should be the same size in practice, say 512 chars. The C code generated for the binding is as follows: SWIGEXPORT jint JNICALL Java_pemapiJNI_DustyVoodoo(JNIEnv *jenv, jclass jcls, jstring jarg1, jint jarg2, jstring jarg3) { jint jresult = 0 ; char *arg1 = (char *) 0 ; int arg2 ; char *arg3 = (char *) 0 ; int result; (void)jenv; (void)jcls; arg1 = 0; if (jarg1) { arg1 = (char *)(*jenv)->GetStringUTFChars(jenv, jarg1, 0); if (!arg1) return 0; } arg2 = (int)jarg2; arg3 = 0; if (jarg3) { arg3 = (char *)(*jenv)->GetStringUTFChars(jenv, jarg3, 0); if (!arg3) return 0; } result = (int)PemnEncrypt(arg1,arg2,arg3); jresult = (jint)result; if (arg1) (*jenv)->ReleaseStringUTFChars(jenv, jarg1, (const char *)arg1); if (arg3) (*jenv)->ReleaseStringUTFChars(jenv, jarg3, (const char *)arg3); return jresult; } It is correct for what it does; however, it misses the fact that cursed is not just an input, it is altered by the function and should be returned as an output. It also does not know that the java Strings are really buffers and should be backed by a suitably sized array. I think that Swig can do the right thing here, I just can't figure out from the documentation how to tell Swig what it needs to know. Any typemap masers in the house?

• Where can I find a list of pushViewController transitions?

  - by barfoon

  Hey everyone, Where can I find a list of transitions for bringing a new Viewcontroller onto the stack. My line of code is: [peoplePicker pushViewController:myDetail transition:6]; after selecting a contact. Where can I find a list of transitions, and why does "6" work correctly? Also I get a warning with this code saying it may not respond to transition, even though it produces the transition correctly. What is the proper way to do these animations? Thanks,

• MinGW/GCC Delay Loaded DLL equivalent?

  - by VoiDeD

  Hello, I'm trying to port some old MSVC C++ code to MinGW/GCC. One problem is that the project relies heavily on the /DELAYLOAD option for functions that aren't always used, and where the proper dll is located at runtime. Is there such a similar option on MinGW/GCC? This code is targeting the windows platform.

• Nokogiri parsing Rackspace return using XPath in Rails

  - by Schroedinger

  Hey guys, I'm using Nokogiri to parse a return from the Rackspace API so I'm using their sample code to response = server.get '/customers/'[email protected]_id.to_s+'/domains/', server.xml_format doc = Nokogiri::XML::parse response.body puts "xpath values" doc.xpath("//name").each do |node| puts node.text end As my code to use Nokogiri to return the nodelist of nodes of the element for some reason I seem to have missed something obvious and I just for the life of me cannot get it to parse the list of nodes and return them to me, is there something simple I can do to fix to have it return the list of nodes?

• Open book PHP test

  - by user275074

  Hi, I have a open-book test this week and I've been notified that the test will be an exercise whereby a chunk of legacy code is provided and a requirement to port the code. I understand what a open-book test is and the requirement of it (to test your thought process etc) but (it's a long shot) what could porting involve? I have a vague idea of what porting is.

• Is there a reason Image.FromFile throws an OutOfMemoryException for an invalid image format?

  - by Arc

  I am writing code that catches this OutOfMemoryException and throws a new, more intuitive exception: /// ... /// <exception cref="FormatException">The file does not have a valid image format.</exception> public static Image OpenImage( string filename ) { try { return Image.FromFile( filename, ); } catch( OutOfMemoryException ex ) { throw new FormatException( "The file does not have a valid image format.", ex ); } } Is this code acceptable to its user, or is OutOfMemoryException intentionally being thrown for a particular reason?

• Biztalk - local variable in expression shape

  - by Jeremy Stein

  Sometimes when I'm writing XLANG/s code in an expression shape, it would be more readable if I could just use a temporary variable within the scope of that one code block. I hate to clutter up the entire orchestration with a variable declaration. Is there a way to declare a variable within an expression shape?

• Does a wrapper class for a COM interop IStream already exist?

  - by AnthonyWJones

  I'm about to write a Wrapper for a COM interop IStream so that code that expects a standard .NET Stream can use it. However it occurs to me that this sort of thing may already have been done before (although I haven't been able to find it myself with web searching). So I'm just putting this out here in case I'm about to re-invent the wheel. Note I've come across code implementing IStream wrapping a .NET stream but I need the reverse.

• How do I read Unicode characters from an MS Access 2007 database through Java?

  - by Peter

  In Java, I have written a program that reads a UTF8 text file. The text file contains a SQL query of the SELECT kind. The program then executes the query on the Microsoft Access 2007 database and writes all fields of the first row to a UTF8 text file. The problem I have is when a row is returned that contains unicode characters, such as "?". These characters show up as "?" in the text file. I know that the text files are read and written correctly, because a dummy UTF8 character ("?") is read from the text file containing the SQL query and written to the text file containing the resulting row. The UTF8 character looks correct when the written text file is opened in Notepad, so the reading and writing of the text files are not part of the problem. This is how I connect to the database and how I execute the SQL query: ---- START CODE Connection c = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:/database.accdb;Pwd=temp"); ResultSet r = c.createStatement().executeQuery(sql); ---- END CODE I have tried making a charSet property to the Connection but it makes no difference: ---- START CODE Properties p = new Properties(); p.put("charSet", "utf-8"); p.put("lc_ctype", "utf-8"); p.put("encoding", "utf-8"); Connection c = DriverManager.getConnection("...", p); ---- END CODE Tried with "utf8"/"UTF8"/"UTF-8", no difference. If I enter "UTF-16" I get the following exception: "java.lang.IllegalArgumentException: Illegal replacement". Been searching around for hours with no results and now turn my hope to you. Please help! I also accept workaround suggestions. =) What I want to be able to do is to make a Unicode query (for example one that searches for posts that contain the "?" character) and to have results with Unicode characters receieved and saved correctly. Thank you!
