• Problem using SQLDMO/Vb6 against SQL2008

  - by E.J. Brennan

  I have a client, that uses SQLDMO for a portion of a custom application that was written against SQL 2000, and they recently upgraded to SQL2008. The majority of the app still runs fine (doesn't use SQLDMO), but the admin functions which rely on SQLDMO stopped working. I installed the SQL2005 backward compatibility pack, and now SQLDMO partially works, i.e. I can run "select" type queries, but any "Update" queries fail with the error message: to connect to the server you must use SQL Server management studio or sql server management objects (SMO) Any thoughts? Should the backward compatibility pack give me ALL the functionality back, or is this a known issue? BTW: I realize SQLDMO has been deprecated and will go away next release, none-the-less I need to do what I can to solve the problem at hand.

• SharePoint Web Services. Using UserPofileService.GetUserProfileByName. After SP upgrade... failing.

  - by Steve

  The below web services code has worked properly for me for over a year. We have updated our SharePoint servers, and now the below code throws an exception (at the bottom line of code) "Object reference not set to an instance of an object" UserProfileWS.UserProfileService userProfileService = new UserProfileWS.UserProfileService(); userProfileService.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials; string serviceloc = "/_vti_bin/UserProfileService.asmx"; userProfileService.Url = _webUrl + serviceloc; UserProfileWS.PropertyData[] info = userProfileService.GetUserProfileByName(null); EDIT: The service is still there. I browse http:///_vti_bin/UserProfileService.asmx, and the information for the service is still there, including the full description of the GetUserProfileByName call. EDIT2: This does appear to be due to a change in SharePoint. I loaded a previous version of my software (known to be working), and it exhibits the same erroneous behavior.

• Ant Copy Task: Failed to copy due to java.io.FileNotFoundException

  - by rfkrocktk

  I'm trying to compile a Flex application in Ant (no problems here, I can do it fine). When I try to publish the contents of the project to a Windows network drive (known as "Z:\" on my system), I get the following LAME exception thrown by Java/Ant: BUILD FAILED C:\workspace\bkeller\build.xml:42: Failed to copy C:\workspace\bkeller\web\assets\text\biography.html to Z:\web\bkeller\assets\text\biography.html due to java.io.FileNotFoundException Z:\web\bkeller\assets\text\biography.html (The system cannot find the file specified) Which kind of sucks. I can't find any way to get rid of this problem and it's pretty crucial to my project that I get this working. I know for sure that I have read/write/execute permissions on the network drive, I can create/edit/delete files on the drive just fine through Windows explorer. Drive Z is a network mount to virtualbox, allowing me to get access to my host OS, Ubuntu. I've double checked that it has write permissions. Any ideas?

• IE dropdown z-index bug

  - by Justine

  I'm having a problem with a dropdown menu under IE (6 and 7). http://www.amaconsulting.pl/promocje.html As you can see, the dropdown hides behind the main content area in IE. It's a known bug and general advice is to set a z-index for header and content areas, so IE knows their "place", explained in the article here: http://bit.ly/coSPcI I've set the z-index of .header div to 20 and .featured, .content, .primary, .main to 1, trying to find the right div to fix the problem. While the dropdown stopped hiding behind the .featured div, it still hides behind the main content divs (either .primary or .main, .secondary is fine). The z-indexes for these divs are set in a separate stylesheet, ie.css, in case someone'll be looking for them. If someone could provide some advice, I'd be very grateful.

• Will you use Delphi Prism

  - by Mohammed Nasman

  CodeGear announces that their Next .Net product which is known as Delphi Prism Will be RemObjects's Oxygene. Oxygene has many nice features that not found in Delphi or C#, and I think it will be a more effective solution for .Net than Delphi .Net previous releases, but it's uses Visual Studio IDE instead of Delphi IDE. which has some cons and pros. As Delphi Developer or .Net Developer, do you consider to use Delphi Prism for .Net developmenet? Look at these Links for more info.

• Why does CLLocationManager returns null locations on the iphone SDK 4 beta in the Simulator?

  - by Rigo Vides

  Hi everyone, I have this piece of code: - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { NSLog(@"Manager did update location!!"); self.currentLocation = newLocation.description; } I have this code inside a class that conforms to the CLLocationManagerDelegate. I tested earlier in sdk 3.0 and works nice (on both simulator and device). I'm testing this class on the SDK 4, in the simulator, but it gives null as a newLocation. I can't even get the NSLog for the first call. I checked other app where I use the location framework and it doesn't work either. I implemented the locationManager:didFailWithError: message also, wich is never called. Can anyone please confirm that the simulator can't do any CLLocationManager capabilities? (a link where the bug is reported as a known issue will be awesome). Is there a way to fix this? Thanks in advance.

• OpenId + Facebook Connect

  - by Claudio Redi

  Hi! I have a request for implementing a login system using local credentials + openId + facebook-connect. So a user could sign up/sign in using any of the 3 possibilities. I think that allowing OpenId AND facebook connect adds some flexibility in one had, but in other hand adds some restrictions since you have to integrate all different logic and make existing differences transparent for users. What do you think? Any good reference for managing federated login using both external mechanisms? Any well known site doing it right now?

• System.Uri can't parse when password field contains a "#"

  - by Andrew

  The following code throws System.UriFormatException: var uri = new UriBuilder("ftp://user:pass#[email protected]:21/fu/bar.zip"); System.UriFormatException: Invalid URI: A port was expected because of there is a colon (':') present but the port could not be parsed. Removing the # symbol from the password field solves the issue. Is a # symbol a valid character to have in the password field? Is there a way to escape this? Is this a known bug in the parsing routine of the Uri class? How does one get around this - assuming you can't change the password? ;-) Thanks, Andrew

• Silently import a Certificate into a specific Certificate Store.

  - by Pieter van Wyk

  Hi. I am attempting to import a Certificate into the Current User - Personal store using the command line: "importpfx -f [certificate name.p12] -p [password] -t USER -s Personal". It works, but for reasons I don't understand there are now two Personal stores under the Current User, and the imported certificate is in the new Personal store. When I try to connect to the website of [a well-known money transfer service], it fails. However, if I manually import the certificate using MMC into the original Personal store, it works. My question is: How can I force IMPORTPFX to import the certificate into the original Personal store, and how can I delete the new Personal store? Context: I need to do a silent import of certificates on 3000+ remote point-of-sale Windows XP devices, so it needs to be a silent install via PSEXEC (SysInternals). Thank you. Pieter.

• sequential search homework question

  - by Phenom

  Consider a disk file containing 100 records a. How many comparisons would be required on the average to find a record using sequential search, if the record is known to be in the file? I figured out that this is 100/2 = 50. b. If the record has a 68% probability of being in the file, how many comparisons are required on average? This is the part I'm having trouble with. At first I thought it was 68% * 50, but then realized that was wrong after thinking about it. Then I thought it was (100% - 68%) * 50, but I still feel that that is wrong. Any hints?

• UIImagePickerController and extracting EXIF data from existing photos

  - by tomtaylor

  It's well known that UIImagePickerController doesn't return the metadata of the photo after selection. However, a couple of apps in the app store (Mobile Fotos, PixelPipe) seem to be able to read the original files and the EXIF data stored within them, enabling the app to extract the geodata from the selected photo. They seem to do this by reading the original file from the /private/var/mobile/Media/DCIM/100APPLE/ folder and running it through an EXIF library. However, I can't work out a way of matching a photo returned from the UIImagePickerController to a file on disk. I've explored file sizes, but the original file is a JPEG, whilst the returned image is a raw UIImage, making it impossible to know the file size of the image that was selected. I'm considering making a table of hashes and matching against the first x pixels of each image. This seems a bit over the top though, and probably quite slow. Any suggestions?

• Debugging with Visual Studio 2010 and VB.NET: Immediate fails due to proection level

  - by marco.ragogna

  It happens quite frequently, more times per day, that with Visual Studio 2010, during the debugging, when I used Immediate commands like: ? NamedVariable I receive the following error: 'NamedVariable' is not declared. It may be inaccessible due to its protection level. In this case also other debug features seems gone, but I can set breakpoints, step into, step over, etc. The solution is stop debugging, clean and rebuild the project, and retry. I am developing a VB.NET Windows Forms application, but it happened with VB.NET WPF projects too. I never had this behavior with VS 2008. Is this a known bug or could it be a problem of my environment/installation? Do you have any idea how to solve this little, but annoying issue?

• Al Zimmermann's Son of Darts

  - by polygenelubricants

  There's about 2 months left in Al Zimmermann's Son of Darts programming contest, and I'd like to improve my standing (currently in the 60s) to something more respectable. I'd like to get some ideas from the great community of stackoverflow on how best to approach this problem. The contest problem is known as the Global Postage Stamp Problem in literatures. I don't have much experience with optimization algorithms (I know of hillclimbing and simulated annealing in concept only from college), and in fact the program that I have right now is basically sheer brute force, which of course isn't feasible for the larger search spaces. Here are some papers on the subject: A Postage Stamp Problem (Alter & Barnett, 1980) Algorithms for Computing the h-Range of the Postage Stamp Problem (Mossige, 1981) A Postage Stamp Problem (Lunnon, 1986) Two New Techniques for Computing Extremal h-bases Ak (Challis, 1992) Any hints and suggestions are welcome. Also, feel free to direct me to the proper site if stackoverflow isn't it.

• Sending emails to site subscribers

  - by Art

  I have a site where people enter their email address to be reminded of a weekly posting. I only send them the weekly email that they double-opt-in for. I do not sell, trade, expose, or do anything else with their address. Right now I have a bit of a hack, connecting to a large email providers SMTP server to send the emails. As the site grows I fear that my emails will be marked as spam and that I will be violating the TOS of the provider. I'm considering two options, building an in-house SMTP server or using a mailing list service. Is there a best-known-method for this? I'd really prefer to simply build my email and use a script to send them through the SMTP server rather then use some GUI to build the email and import a list of addresses. But previous experience tells me that running a mail server and not being marked as spam can be difficult. Help!?

• UIView Animation: PartialCurl ...bug during rotate?

  - by itai alter

  Hello all, a short question. I've created an app for the iPad, much like a utility app for the iPhone (one mainView, one flipSideView). The animation between them is UIModalTransitionStylePartialCurl. shouldAutorotateToInterfaceOrientation is returning YES. If I rotate the device BEFORE entering the FlipSide, everything is okay and the PartialCurl is displayed okay. But if I enter the FlipSide and then rotate the device, while the UIElements do rotate and position themselves just fine, the actual "page curl" stays with its initial orientation. it just won't budge :) Is it a known issue? am I doing something wrong? Thanks!

• Java: notify() vs. notifyAll() all over again

  - by Sergey Mikhanov

  If one google for "difference between notify() and notifyAll()" then a lot of explanations will pop up (leaving apart the javadoc paragraphs). It all boils down to the number of waiting threads being waken up: one in notify() and all in notifyAll(). However (if I do understand the difference between these methods right), only one thread is always selected for further monitor acquisition; in the first case the one selected by the VM, in the second case the one selected by the system thread scheduler. The exact selection procedures for both of them (in general case) are not known to the programmer. What's is the useful difference between notify() and notifyAll() then? Am I missing something?

• Fields_for dynamic label

  - by sebajb

  I have dynamic form which has a set of values. I created a partial which contains text fields which I display. Next to each of them I would like to display a label containing the title of the text. For instance First Name, and Last Name would not be known previously. How do I go about doing that? It seems that I cannot access the attributes directly. But when I use the label field, the variable name in the label is displayed not the actual value.

• Does Java support dynamic method invocation?

  - by eSKay

  class A { void F() { System.out.println("a"); }} class B extends A { void F() { System.out.println("b"); }} public class X { public static void main(String[] args) { A objA = new B(); objA.F(); } } Here, F() is being invoked dynamically, isn't it? This article says ... the Java bytecode doesn’t support dynamic method invocation. There are three supported invocations modes : invokestatic, invokespecial, invokeinterface or invokevirtual. These modes allows to call methods with known signature. We talk of strongly typed language. This allows to to make some checks directly at compile time. On the other side, the dynamic languages use dynamic types. So we can call a method unknown at the compile time, but that’s completely impossible with the Java bytecode. What am I missing?

• Scheme: Detecting duplicate elements in a list

  - by Kyle Krull

  Does R6RS or Chez Scheme v7.9.4 have a library function to check if a list contains duplicate elements? Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here. The problem with that is that it doesn't appear to actually be part of the Chez Scheme library. Although I could write my own version of this, I'd much rather use a well known, tested, and maintained library function - especially given how basic an operation this is. So a simple "use these built-in functions" or a "no built-in library implements this" will suffice. Thanks!

• Automate Google Chrome extension installation

  - by gtaborga

  Hi everyone, I am working on creating a Google Chrome extension. We have it included in an automated build system and since it is constantly being worked on we need a solution to be able to package the extension as a .crx file which according to http://code.google.com/chrome/extensions/packaging.html can easily be scripted. My question is after packaging the extension is there a known method either through the command-line or some other programmatic way, to install the newly packaged extension in an automated manner? If someone knows how or has any reference material that I can be pointed towards I would greatly appreciate any help that is offered. Thank you.

• Android compatibility with Restlet/JSON/Jackson

  - by Cookie

  Hi there, I'm currently working on a webservice-client for Android. I'm using a Java client library which provides an abstraction for interaction with the service. The client library works on normal machines. However, when I use the classes in my Android project, some calls don't return a result on Android, the background-service stops working at the first of those commands. Wireshark shows a tcp exchange, the server gets the requests. There is no exceptions or anything. Something in the serialization/deserialization semms not to work. I'm using the newest version of Jackson libraries (1.5.3) and the restlet jar in the android edition. Is there any known problems with Jackson and Android? Which code and libraries are compatible with Android? Thanks in advance.

• Debugging FLEX/AS3 memory leaks

  - by Scott Evernden

  I have a pretty big Flex & Papervision3D application that creates and destroys objects continually. It also loads and unloads SWF resource files too. While it's running the SWF slowly consumes memory til about 2GB when it croaks the player. Obviously I am pretty sure I let go of reference to instances I no longer want with expectation the GC will do its job. But I am having a heck of a time figuring out where the problem lies. I've tried using the profiler and its options for capturing memory snapshots, etc - but my problem remains evasive. I think there are known problems using debug Flash player also? But I get no joy using the release version either. How do you go about tracking down memory leak problems using FLEX/AS3 ? What are some strategies, tricks, or tools you have used to locate consumption

• Is J2EE/EJBs a dying trend?

  - by Taranfx

  I might be wrong on this, but I no longer see heavy Business and Web services being hosted using J2ee technologies (Especially EJBs). Having known the power and scalability of J2ee applications, what is keeping developers/decision makers to restrict themselves to Core Java (POJOs) or even other web technologies like PHP, python. Is it the development time? Is it the Ease of configuration? (I feel this should not be a strong reason with Java EE 6, things are simplified) Of course scripting languages are faster to develop, we cannot ignore the fact that they are inherently not-as-scalable as Java Applications are (using App servers)
