• PHP site keeps opening to blank page, no errors.

  - by gene

  First, the premises: PHP loaded on IIS6 on Win2003 STD R2 SP2, PHP_5213 using FastCGI, MySQL_5145. Customer sent me the site files, which I unzipped to C:\InetPub\wwwroot\<site root>, then I created a new site in IIS, pointed to <site root>, added test.php to the site files for testing and it works, but visiting index.php produces a blank page with no errors. The readme.txt file present makes reference to application.php and explains root folder var and sets it to a non-existent file. I don't know PHP syntax, but I tried several logical changes with zero results. At this point I'm not even sure if that is the problem anymore. With PHP, MySQL & site debugging have put in over 20 hours. Still confused, I have resorted to heavy drug use and purchased a small firearm, loaded with a single round (even this seemed to take an inordinate amount of time). I've given up all hope. Someone please help save a new server and/or old administrator.

• Call by Reference Function in C

  - by Chad

  Hello everyone, I would just like a push in the right direction here with my homework assignment. Here is the question: (1) Write a C function called input which returns void, this function prompts the user for input of two integers followed by a double precision value. This function reads these values from the keyboard and finds the product of the two integers entered. The function uses call by reference to communicate the values of the three values read and the product calculated back to the main program. The main program then prints the three values read and the product calculated. Provide test results for the input: 3 5 23.5. Do not use arrays or global variables in your program. And here is my code: #include <stdio.h> #include <stdlib.h> void input(int *day, int *month, double *k, double *pro); int main(void){ int i,j; double k, pro; input(&i, &j, &k, &pro); printf("%f\n", pro); return 0; } void input(int *i, int *j, double *k, double *pro){ int x,y; double z; double product; scanf("%d", &x); scanf("%d", &y); scanf("%f", &z); *pro += (x * y * z); } I can't figure out how to reference the variables with pointers really, it is just not working out for me. Any help would be great!

• setInterval works only the first time

  - by Neil

  Hi, I am trying to use setTimer to animate a slide show using straightforward jQuery. I provide the user with a button (in the form of a "DIV" with a button background image) that he clicks to start the show and which then turns into a pause button. The slides are supposed to change every 3 seconds. Here is the relevant code: playLink = $('<div id="lbPlayLink" />').click(function(){ $(playLink).hide(); $(pauseLink).show(); slideInterval = setInterval(function(){next()}, 3000) })[0]; pauseLink = $('<div id="lbPauseLink" />').click(function(){ $(playLink).show(); $(pauseLink).hide(); clearInterval(slideInterval); }).hide()[0]; The next() function call does the work of replacing the slide with the next one. I have checked out this function and it works perfectly if I call it directly (synchronously), however, when it gets called asonchronously by the "setInterval", it works fine the first time (3 seconds after I click on the button), but is never called again, even though it should be called 3 seconds later. I know it's never called as I put an "alert" call at the beginning and end of the function. If I replace the "next()" call in the "setInterval" by "alert('test')" then I can see the setInterval is doing what it is supposed to. I can't for the life of me see why "alert()" is OK but "next()" isn't, unless it has something to do with "scope" of functions, but in that case why does it work the first time? I've tried debugging the code with firebug, but it can't really help with timeout functions like this. Neither Firefox nor IE8 show any error messages. I've looked through the various posts here and elsewhere on setInterval, but can't see anything relevant that I haven't tried already. I've been experimenting now for about 3 hours and it's doing my head in. Can anyone suggest what I can try next? Thanks in advance Neil

• android & libgdx - disable blurry images rendering

  - by android developer

  i'm trying out libgdx as an opengl wrapper , and i have some issues with its graphical rendering : for some reason , all images (textures) on android device look a little blurred using libgdx . this also includes text (font) . however, for normal images , even though i show the entire image , i expect it to look as sharp as i see it on a computer , especially if i have such a good screen on the device (it's galaxy nexus) . i've tried to set the anti-aliasing off , by using the next code : final AndroidApplicationConfiguration androidApplicationConfiguration=new AndroidApplicationConfiguration(); androidApplicationConfiguration.numSamples=0; //tried the value of 1 too. ... i've also tried to set the scaling method to various methods , but with no luck. example: texture.setFilter(TextureFilter.Nearest,TextureFilter.Nearest); as a test , i've found a sharp image that is exactly the same as the seen resolution on the device (720x1184 for galaxy nexus , because of the buttons bar) , and i've put it to be on the background of the libgdx app . of course , i had to add extra blank space in order for the texute to be loaded , so the final size of the image (which will include content and empty space) is still a power of 2 for both width and height (1024x2048 in my case) . on the desktop app , it look ok . on the device , it looked blurred. a weird thing that i've noticed is that when i change the device's orientation (horizontal <= vertical) , for the very short time before the rotating animation starts , i see both the image and the text very well . can anyone please help me?

• Why does output of fltk-config truncate arguments to gcc?

  - by James Morris

  I'm trying to build an application I've downloaded which uses the SCONS "make replacement" and the Fast Light Tool Kit Gui. The SConstruct code to detect the presence of fltk is: guienv = Environment(CPPFLAGS = '') guiconf = Configure(guienv) if not guiconf.CheckLibWithHeader('lo', 'lo/lo.h','c'): print 'Did not find liblo for OSC, exiting!' Exit(1) if not guiconf.CheckLibWithHeader('fltk', 'FL/Fl.H','c++'): print 'Did not find FLTK for the gui, exiting!' Exit(1) Unfortunately, on my (Gentoo Linux) system, and many others (Linux distributions) this can be quite troublesome if the package manager allows the simultaneous install of FLTK-1 and FLTK-2. I have attempted to modify the SConstruct file to use fltk-config --cflags and fltk-config --ldflags (or fltk-config --libs might be better than ldflags) by adding them like so: guienv.Append(CPPPATH = os.popen('fltk-config --cflags').read()) guienv.Append(LIBPATH = os.popen('fltk-config --ldflags').read()) But this causes the test for liblo to fail! Looking in config.log shows how it failed: scons: Configure: Checking for C library lo... gcc -o .sconf_temp/conftest_4.o -c "-I/usr/include/fltk-1.1 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT" gcc: no input files scons: Configure: no How should this really be done? And to complete my answer, how do I remove the quotes from the result of os.popen( 'command').read()? EDIT The real question here is why does appending the output of fltk-config cause gcc to not receive the filename argument it is supposed to compile?

• (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user

  - by ChelleATL

  I am trying to deploy a report to the Reporting Services Server but keep running up against this error: An error occurred during client rendering. An error has occurred during report processing. (rsProcessingAborted) Cannot create a connection to data source 'dataSource1'. (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user 'DOMAIN\useradmin', error code 0x5. Here’s my situation: Everything is being ran using DOMAIN\useradmin and the report is using a remote database. Reporting Services and SQL Server are both ran under DOMAIN\useradmin. DOMAIN\useradmin is a windows AD login and is part of the server machine Administrators group. My test report is using a data source model that in turn is using a data source that is connection to a database on a different SQL Server. The data source is using “Credentials stored securely in the report server” with the options “Use as Windows credentials when connecting to the data source” and “Impersonate the authenticated user after a connection has been made to the data source.” I am using the credentials of DOMAIN\useradmin that is the db owner of the remote database. DOMAIN\useradmin is assigned the roles, System Administrator, System User and Browser, Content Manager, My Reports, Publisher, Report Builder. So if everything is being run under an über AD account, why I am getting this Could not obtain information about Windows NT group/user 'DOMAIN\useradmin' error? Under normal circumstances , an AD login with Publisher permissions will developing reports using a datasource model created by DOMAIN\useradmin but using one of the remote database’s users which is mapped from yet another AD login. I ran the following statements and non errors were returned: use master go xp_grantlogin 'DOMAIN\useradmin' go xp_logininfo 'DOMAIN\useradmin' go

• Merging changes to a workspace with uncommitted changes

  - by Kim L

  We've just recently switched over from SVN to Mercurial, but now we are running into problems with our workflow. Example I have my local clone of the repository which I work on. I'm making some highly experimental changes to our code base, something that I don't want to commit before I'm sure it works the way it is supposed to, I don't want to commit it even locally. Now, simultaneously, my co-worker has made some significant improvements/bug fixes which I need. He pushes his commits to our main repository. The question is, how can I merge his changes to my workspace without the requirement that I have to commit all my changes, since I need his changes to test my own code? A more day-to-day problem we have with the exact same workflow is where we have a couple of configuration files which are in the repository. Each developer makes a couple of small environment specific changes to the configuration files, but do not commit the changes. These couple of uncommitted files hinders us from making any merges to our workspace, just like with the example above. Ideally, the configuration files probably shouldn't be in the repository, unfortunately, that's just how it has to be for here unnamed reasons.

• Reading UTF-8 XML and writing it to a file with Python

  - by Harri

  I'm trying to parse UTF-8 XML file and save some parts of it to another file. Problem is, that this is my first Python script ever and I'm totally confused about the character encoding problems I'm finding. My script fails immediately when it tries to write non-ascii character to a file, but it can print it to command prompt (at least in some level) Here's the XML (from the parts that matter at least, it's a *.resx file which contains UI strings) <?xml version="1.0" encoding="utf-8"?> <root> <resheader name="foo"> <value>bar</value> </resheader> <data name="lorem" xml:space="preserve"> <value>ipsum öä</value> </data> </root> And here's my python script from xml.dom.minidom import parse names = [] values = [] def getStrings(path): dom = parse(path) data = dom.getElementsByTagName("data") for i in range(len(data)): name = data[i].getAttribute("name") names.append(name) value = data[i].getElementsByTagName("value") values.append(value[0].firstChild.nodeValue.encode("utf-8")) def writeToFile(): with open("uiStrings-fi.py", "w") as f: for i in range(len(names)): line = names[i] + '="'+ values[i] + '"' #varName='varValue' f.write(line) f.write("\n") getStrings("ResourceFile.fi-FI.resx") writeToFile() And here's the traceback: Traceback (most recent call last): File "GenerateLanguageFiles.py", line 24, in writeToFile() File "GenerateLanguageFiles.py", line 19, in writeToFile line = names[i] + '="'+ values[i] + '"' #varName='varValue' UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 2: ordinal not in ran ge(128) How should I fix my script so it would read and write UTF-8 characters properly? The files I'm trying to generate would be used in test automation with Robots Framework.

• Web Servicet Client in JBOSS 5.1 with JDK6

  - by dcp

  This is a continuation of the question here: http://stackoverflow.com/questions/2435286/jboss-does-app-have-to-be-compiled-under-same-jdk-as-jboss-is-running-under It's different enough though that it required a new question. I am trying to use jdk6 to run JBOSS 5.1, and I downloaded the JDK6 version of JBOSS 5.1. This works fine and my EAR application deploys fine. However, when I want to run a web service client with code like this: public static void main(String[] args) throws Exception { System.out.println("creating the web service client..."); TestClient client = new TestClient("http://localhost:8080/tc_test_project-tc_test_project/TestBean?wsdl"); Test service = client.getTestPort(); System.out.println("calling service.retrieveAll() using the service client"); List<TestEntity> list = service.retrieveAll(); System.out.println("the number of elements in list retrieved using the client is " + list.size()); } I get the following exception: javax.xml.ws.WebServiceException: java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage at org.jboss.ws.core.jaxws.client.ClientImpl.handleRemoteException(ClientImpl.java:396) at org.jboss.ws.core.jaxws.client.ClientImpl.invoke(ClientImpl.java:302) at org.jboss.ws.core.jaxws.client.ClientProxy.invoke(ClientProxy.java:170) at org.jboss.ws.core.jaxws.client.ClientProxy.invoke(ClientProxy.java:150) Now, here's the really interesting part. If I change the JDK that my the code above is running under from JDK6 to JDK5, the exception above goes away! It's really strange. The only way I found for the code above to run under JDK6 was to take the JBOSS_HOME/lib/endorsed folder and copy it to JDK6_HOME/lib. This seems like it shouldn't be necessary, but it is. Is there any other way to make this work other than using the workaround I just described?

• Hudson fails to use unix user/group to do authentication

  - by Kane

  I'm trying to use unix user/group database as security realm of hudson. The linux server is using NIS for user management. My account could login the hudson server via ssh. And the hudson server is running by user 'hudson' that is also a member of group 'shadow', so hudson could read /etc/shadow. And I tested the configuration using 'test' button, hudson tells me it works well. But I can't use my unix account and password to login the hudson sever.

• Why do I have to unserialize this serialized value twice? (wordpress/bbpress maybe_serialize)

  - by 55skidoo

  What am I doing wrong here? I'm serializing a value, storing it in a database (table bb_meta), retrieving it... OK so far... but then I have to unserialize it twice. Shouldn't I be able to just unserialize once? This seems to work, but I'm wondering what point about serialization I'm missing here. //check database to see if user has ever visited before. $querystring = $bbdb->prepare( "SELECT `meta_value` FROM `$bbdb->meta` WHERE `object_type` = %s AND `object_id` = %s AND `meta_key` = %s LIMIT 1", $bbtype, $bb_this_thread, $bbuser ); $bb_last_visits = $bbdb->get_row($querystring, OBJECT); //if $bb_last_visits is empty, add time() as the metavalue using bb_update_meta if (empty($bb_last_visits)) { $first_visit = time(); echo 'serialized first visit: ' . $bb_this_visit_time_serialized = serialize(array($bb_this_thread => $first_visit)); bb_update_meta( $bb_this_thread, $bbuser, $bb_this_visit_time_serialized, $bbtype ); //add to database, bb_meta table echo '$bb_last_visits was empty.

• A dynamic array of class "landmark", inside another single class "landmarks"

  - by pinnacler

  I'm working on a robot localization simulator and I created a class called "landmark". The end result is going to be a robot that is always centered and always faces the top of the screen. As it turns, the birds eye view map will rotate around the robot. To accomplish this, I'm assuming I can rotate one class and have all elements inside rotate as well. So, the landmark class has properties x,y, label, and radius. This is suppose to simulate a tree location in a forest. To test everything, I need "forest data," and I wrote a script to generate 100 trees in a 100m x 100m area. The script automatically generates values within an acceptable range for x,y, radius. The generated data is stored in an object called tempForest and is 100x3. Ideally, I want to create a class called "landmarks" (plural) that has 100 landmark instances inside. How would I instantiate 100 instances of landmark in one instance of landmarks using that randomly generated data? Ideally, I'd just type treeBeacons = landmarks(); and it would randomly populate 100 (user definable, set in config file) instances with x, y, radius data. I'm not sure how to deal with a dynamic array of class "Landmark", inside another single class "landmarks." Any ideas?

• How do I programmatically create a bootable CD?

  - by Nicholas Flynt

  I'm using a barebones tutorial as the basis for an OS I'm working on, and it seems to be an older tutorial: it has be compiling the kernel down to a floppy image, and then loading it with GRUB. Basically, I still want to use GRUB, but I'd like to have my OS run from a CD instead. The main reason is that I don't actually have a real floppy drive available (I'm testing in VirtualBox currently) and I thus have no way to test my OS on real hardware. I've been poking around on the net, and I can find lots of utilities that create a bootable CD from a floppy image, but these all seem to require an actual floppy drive, plus it's not really what I'm looking for. I'd like to be able to end up with a bootable CD during my make step ideally, without needing to first place the image on a floppy, which seems rather pointless. I guess the easy way to answer this: How do I set up GRUB to read my kernel image from a CD? Will I need a special utility to do this from Windows? (The kernel can't compile itself yet, that's not for a looong while) Thanks!

• Extension methods conflict

  - by Yochai Timmer

  Lets say I have 2 extension methods to string, in 2 different namespaces: namespace test1 { public static class MyExtensions { public static int TestMethod(this String str) { return 1; } } } namespace test2 { public static class MyExtensions2 { public static int TestMethod(this String str) { return 2; } } } These methods are just for example, they don't really do anything. Now lets consider this piece of code: using System; using test1; using test2; namespace blah { public static class Blah { public Blah() { string a = "test"; int i = a.TestMethod(); //Which one is chosen ? } } } I know that only one of the extension methods will be chosen. Which one will it be ? and why ? How can I choose a certain method from a certain namespace ? Edit: Usually I'd use Namespace.ClassNAME.Method() ... But that just beats the whole idea of extension methods. And I don't think you can use Variable.Namespace.Method()

• Symfony fk issue on insertion

  Hi, I posted a similar problem but it could not be resolved. I create a relational database of users and groups but for some reason I cannot insert test data with fixtures properly. Here is a sample of the schema: User: actAs: { Timestampable: ~ } columns: name: { type: string(255), notnull: true } email: { type: string(255), notnull: true, unique: true } nickname: { type: string(255), unique: true } password: { type: string(300), notnull: true } image: { type: string(255) } Group: actAs: { Timestampable: ~ } columns: name: { type: string(500), notnull: true } image: { type: string(255) } type: { type: string(255), notnull: true } created_by_id: { type: integer } relations: User: { onDelete: SET NULL, class: User, local: created_by_id, foreign: id, foreignAlias: groups_created } FanOf: actAs: { Timestampable: ~ } columns: user_id: { type: integer, primary: true } group_id: { type: integer, primary: true } relations: User: { onDelete: CASCADE, local: user_id, foreign: id, foreignAlias: fanhood } Group: { onDelete: CASCADE, local: group_id, foreign: id, foreignAlias: fanhood } And this is the data i try to input: User: user1: name: Danny email: [email protected] nickname: danny password: f05050400c5e586fa6629ef497be Group: group1: name: Mets type: sports FanOf: fans1: user_id: user1 group_id: group1 I keep getting this error: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`krowdd`.`fan_of`, CONSTRAINT `fan_of_user_id_user_id` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE CASCADE) The users and groups are clearly being created before the "fanhood" is so why am I getting this error??

• Tips on managing dependencies for a release?

  - by Andrew Murray

  Our system comprises many .NET websites, class libraries, and a MSSQL database. We use SVN for source control and TeamCity to automatically build to a Test server. Our team is normally working on 4 or 5 projects at a time. We try to lump many changes into a largish rollout every 2-4 weeks. My problem is with keeping track of all the dependencies for a rollout. Example: Website A cannot go live until we've rolled out Branch X of Class library B, built in turn against the Trunk of Class library C, which needs Config Updates Y and Z and Database Update D, which needs Migration Script E... It gets even more complex - like making sure each developer's project is actually compatible with the others and are building against the same versions. Yes, this is a management issue as much as a technical issue. Currently our non-optimal solution is: a whiteboard listing features that haven't gone live yet relying on our memory and intuition when planning the rollout, until we're pretty sure we've thought of everything... a dry-run on our Staging environment. It's a good indication but we're often not sure if Staging is 100% in sync with Live - part of the problem I'm hoping to solve. some amount of winging it on rollout day. So far so good, minus a few close calls. But as our system grows, I'd like a more scientific release management system allowing for more flexibility, like being able to roll out a single change or bugfix on it's own, safe in the knowledge that it won't break anything else. I'm guessing the best solution involves some sort of version numbering system, and perhaps using a project management tool. We're a start-up, so we're not too hot on religiously sticking to rigid processes, but we're happy to start, providing it doesn't add more overhead than it's worth. I'd love to hear advice from other teams who have solved this problem.

• How can I include additional markup within a 'Content' inner property within an ASP.Net WebControl?

  - by GenericTypeTea

  I've searched the site and I cannot find a solution for my problem, so apologies if it's already been answered (I'm sure someone must have asked this before). I have written a jQuery Popup window that I've packaged up as a WebControl and IScriptControl. The last step is to be able to write the markup within the tags of my control. I've used the InnerProperty attribute a few times, but only for including lists of strongly typed classes. Here's my property on the WebControl: [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public something??? Content { get { if (_content == null) { _content = new something???(); } return _content; } } private something??? _content; Here's the HTML Markup of what I'm after: <ctr:WebPopup runat="server" ID="win_Test" Hidden="false" Width="100px" Height="100px" Modal="true" WindowCaption="Test Window" CssClass="window"> <Content> <div style="display:none;"> <asp:Button runat="server" ID="Button1" OnClick="Button1_Click" /> </div> <%--Etc--%> <%--Etc--%> </Content> </ctr:WebPopup> Unfortunately I don't know what type my Content property should be. I basically need to replicate the UpdatePanel's ContentTemplate. EDIT: So the following allows a Template container to be automatically created, but no controls show up, what's wrong with what I'm doing? [PersistenceMode(PersistenceMode.InnerProperty)] [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)] public ITemplate Content { get { return _content; } set { _content = value; } } private ITemplate _content;

  I am using Cocos2D for my main framework. In some cases, I want Cocos2D to load a nib file and have that be the view: window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; TargetPlayerViewController *myController = [[TargetPlayerViewController alloc]initWithNibName:@"TargetPlayerViewController" bundle:nil]; [window addSubview:[myController view]]; [window makeKeyAndVisible]; This works as expected, and shows the TargetPlayerViewController. Wonderful! What I need to know is: once that view has been loaded, how can I have the view remove itself? I've tried a few different ways, but all of them result in the program crashing. To test I have a button on the view set up which triggers this method: - (IBAction)GTFOnow:(id)sender { NSLog(@"GFTO"); window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; //[self.view removeFromSuperview]; //[window makeKeyAndVisible]; } In this method the view should remove itself from the view so I can go back to the Cocos2D. How do I do this?

• MySQL-python 1.2.3 and OS X 10.5: 64- or 32-bit?

  - by Dave Everitt

  I've been happily using Django and MySQL in development on an existing machine running OS X 10.4 Tiger, and have set up a similar environment in 10.5 Leopard on a new 64-bit MacBook, with a working MySQL and Python 2.6.4. However, now I want them to communicate, easy_install MySQL-python gave ld warnings that the file is not of the required architecture, which led me to test my Python 2.4.6 install (from the Mac OS X disc image): >>> import sys >>> sys.maxint 2147483647 Ah. So my Python install appears to be 32-bit and (I think?) won't install MySQL-python for my 64-bit MySQL. There are lots of hacks out there for MySQL-python on OS X (mostly 1.2.2), but - after hours of reading - I'm pretty sure they won't fix this architecture mismatch. So I'm stuck because I can't decide whether to: give up, remove the 64-bit MySQL install (thorough methods, please?) and use the 32-bit MySQL disc image instead; re-install Python in 64-bit mode from the tarball, --with-universal archs-64-bit and --enable-universalsdk= as detailed in Python.org's 2.6 news. So my questions for anyone who has encountered this issue are: Is installing 64-bit Python on OS X 10.5 worth bothering with? If so, (naive, lazy question!) how are the two required arguments combined? If I just skip along in 32-bit (as on my working setup) what am I missing? I'm after a hassle-free install that's easy to reproduce on other machines (possible student use) so I'd really welcome your opinions, please!

• Use Objective-C without NSObject?

  - by Alex I

  I am testing some simple Objective-C code on Windows (cygwin, gcc). This code already works in Xcode on Mac. I would like to convert my objects to not subclass NSObject (or anything else, lol). Is this possible, and how? What I have so far: // MyObject.h @interface MyObject - (void)myMethod:(int) param; @end and // MyObject.m #include "MyObject.h" @interface MyObject() { // this line is a syntax error, why? int _field; } @end @implementation MyObject - (id)init { // what goes in here? return self; } - (void)myMethod:(int) param { _field = param; } @end What happens when I try compiling it: gcc -o test MyObject.m -lobjc MyObject.m:4:1: error: expected identifier or ‘(’ before ‘{’ token MyObject.m: In function ‘-[MyObject myMethod:]’: MyObject.m:17:3: error: ‘_field’ undeclared (first use in this function) EDIT My compiler is cygwin's gcc, also has cygwin gcc-objc package: gcc --version gcc (GCC) 4.7.3 I have tried looking for this online and in a couple of Objective-C tutorials, but every example of a class I have found inherits from NSObject. Is it really impossible to write Objective-C without Cocoa or some kind of Cocoa replacement that provides NSObject? (Yes, I know about GNUstep. I would really rather avoid that if possible...)

• VBA Macro to save an excel file to a different backup location

  - by Joe Taylor

  I am trying to create a Macro that either runs on close or on save to backup the file to a different location. At the moment the Macro I have used is: Private Sub Workbook_BeforeClose(Cancel As Boolean) 'Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean) 'Saves the current file to a backup folder and the default folder 'Note that any backup is overwritten Application.DisplayAlerts = False ActiveWorkbook.SaveCopyAs Filename:="T:\TEC_SERV\Backup file folder - DO NOT DELETE\" & _ ActiveWorkbook.Name ActiveWorkbook.Save Application.DisplayAlerts = True End Sub This creates a backup of the file ok the first time, however if this is tried again I get: Run-Time Error '1004'; Microsoft Office Excel cannot access the file 'T:\TEC_SERV\Backup file folder - DO NOT DELETE\Test Macro Sheet.xlsm. There are several possible reasons: The file name or path does not exist The file is being used by another program The workbook you are trying to save has the same name as a... I know the path is correct, I also know that the file is not open anywhere else. The workbook has the same name as the one I'm trying to save over but it should just overwrite. Any help would be much appreciated. Joe

• unable to find a MessageBodyReader

  - by Cristian Boariu

  Hi guys, I have this interface: @Path("inbox") public interface InboxQueryResourceTest { @POST @Path("{membershipExternalId}/query") @Consumes(MediaType.APPLICATION_XML) @Produces("multipart/mixed") public MultipartOutput query(@PathParam("membershipExternalId") final String membershipExternalId, @QueryParam("page") @DefaultValue("0") final int page, @QueryParam("pageSize") @DefaultValue("10") final int pageSize, @QueryParam("sortProperty") final List<String> sortPropertyList, @QueryParam("sortReversed") final List<Boolean> sortReversed, @QueryParam("sortType") final List<String> sortTypeString, final InstanceQuery instanceQuery) throws IOException; } I have implemented the method to return a MultipartOutput. I am posting an xml query from Fiddler and i receive the result without any problem. BUT i have done an integration test for the same interface, i send the same objects and i put the response like: final MultipartOutput multiPartOutput = getClient().query(getUserRestAuth(), 0, 25, null, null, null, instanceQuery); But here, so from integration tests, i receive a strange error: Unable to find a MessageBodyReader of content-type multipart/mixed;boundary="74c5b6b4-e820-452d-abea-4c56ffb514bb" and type class org.jboss.resteasy.plugins.providers.multipart.MultipartOutput Anyone has any ideea why only in integration tests i receive this error? PS: Some of you will say that i do not send application/xml as ContentType but multipart, which of course is false because the objects are annotated with the required @XmlRootElement etc, otherways neither the POST from Fiddler would work.

• On Windows 7: Same path but Explorer & Java see different files than Powershell

  - by Ukko

  Submitted for your approval, a story about a poor little java process trapped in the twilight zone... Before I throw up my hands and just say that the NTFS partition is borked is there any rational explanation of what I am seeing. I have a file with a path like this C:\Program Files\Company\product\config\file.xml I am reading this file after an upgrade and seeing something wonky. Eclipse and my Java app are still seeing the old version of this file while some other programs see the new version. The test that convinced my it was not my fat finger that caused the problem was this: In Explorer I entered the above path and Explorer displayed the old version of the file. Forcing Explorer to reload via Ctrl-F5 still yields the old version. This is the behavior I get in Java. Now in PowerShell I enter more "C:\Program Files\Company\product\config\file.xml" I cut and past the path from Explorer to make sure I am not screwing anything up and it shows me the new version of the file. So for the programming aspect of this, is there a cache or some system component that would be storing this stale reference. Am I responsible for checking or reseting that for some class of files. I can imagine somebody being "creative" in how xml files are processed to provide some bell or whistle. But it could be a case of just being borked. Any insights appreciated...Thanks!

• Locking behaviour is different via network shares

  - by MattH

  I have been trying to lock a file so that other cloned services cannot access the file. I then read the file, and then move the file when finished. The Move is allowed by using FileShare.Delete. However in later testing, we found that this approach does not work if we are looking at a network share. I appreciate my approach may not have been the best, but my specific question is: Why does the below demo work against the local file, but not against the network file? The more specific you can be the better, as I've found very little information in my searches that indicates network shares behave differently to local disks. string sourceFile = @"C:\TestFile.txt"; string localPath = @"C:\MyLocalFolder\TestFile.txt"; string networkPath = @"\\MyMachine\MyNetworkFolder\TestFile.txt"; File.WriteAllText(sourceFile, "Test data"); if (!File.Exists(localPath)) File.Copy(sourceFile, localPath); foreach (string path in new string[] { localPath, networkPath }) { using (FileStream fsLock = File.Open(path, FileMode.Open, FileAccess.ReadWrite, (FileShare.Read | FileShare.Delete))) { string target = path + ".out"; File.Move(path, target); //This is the point of failure, when working with networkPath if (File.Exists(target)) File.Delete(target); } if (!File.Exists(path)) File.Copy(sourceFile, path); }
