• How Do You Insert Large Blobs Into Oracle 10G Using System.Data.OracleClient?

  - by discwiz

  Trying to insert 315K Gif files into an Oracle 10g database. Everytime I get this error "ora-01460: unimplemented or unreasonable conversion requested" whe I run the stored procedure. It appears that there is a 32K limit if I use a stored procedure. I read online that this does not apply if you are doing a direct insert, but I do not know how to create the insert string for a Byte Array. This is a thick client running on the server so not worried about SQL Injection attacks. Any help would be greatly appreciated. FYI, code in vb.net. Thanks, Dave

• Jquery galleryView loading issues: loader image not displaying, taking awhile

  - by Dustin

  I've got an online portfolio that I'm putting up: Image Gallery I've got a php script that selects at most 15 images from a database that contains the urls for the images. e.g. foreach ($database-result as $img) { echo '<a href="path/to/image/' . $img . '">'; ? When the page first loads, the scroll bar expands as if it is loading invisible images (indeed I think that's what it is doing). Then the javascript kicks in and the gallery loads. I have two questions: first, the image loader is not displaying at all. I don't mind if it takes a bit, as long as the user knows the images are loading. Any ideas why it's not showing up? Second, is there a way to speed up the process? Thanks in advance for the help!

• With windows authentication, The trust relationship between the primary domain and the trusted domai

  - by yamspog

  I have my asp.net web server setup to use windows authentication. It is authenticating just fine with my current logged in user. I can verify this by viewing ... HttpContext.Current.User.Identity.Name And I can verify that I am authenticated by viewing... HttpContext.Current.User.Identity.IsAuthenticated However, when I call the .IsInRole function I get the trust relationship error... HttpContext.Current.User.IsInRole("accounting") I have found online references to problems with supplying domain name with the role name (domain\accounting), but I still get the same error. Any suggestions on where to look or troubleshoot the problem?

• naive bayesian spam filter question

  - by Microkernel

  Hi guys, I am planning to implement spam filter using Naive Bayesian classification model. Online I see a lot of info on Naive Bayesian classification, but the problem is its a lot of mathematical stuff, than clearly stating how its done. And the problem is I am more of a programmer than a mathematician (yes I had learnt Probability and Bayesian theorem back in school, but out of touch for a long long time, and I don't have luxury of learning it now (Have nearly 3 weeks to come-up with a working prototype)). So if someone can explain or point me to location where its explained for programmers than a mathematician, it would be a great help. PS: By the way I have to implement it in C, if you want to know. :( Regards, Microkernel

• get img src from an img loaded dynamically using jQuery

  - by Lee

  Hey Guys (and Ladies) I am looking at getting the image name from an image with a src loaded dynamically. Basically what I am doing is using the Google chat badge on a site to live chatting. And else where on the page, I have an image saying Live Chat:Online or Live Chat:Offline. And I want this to change depending on whether I am available to chat or not. Does this make sense? Anyway, the easiest way I figure to do this would be check the img url. If the img is offline.gif then obviously I am offline. An example of a dynamically loaded img would be something like <img src="http://www.google.com/talk/service/badge/Show?encrypted_acount_id_here" /> Once this image has loaded, it loads one of the following images "http://www.google.com/talk/service/resources/offlinef.gif" "http://www.google.com/talk/service/resources/idlef.gif" "http://www.google.com/talk/service/resources/onlinef.gif" Hopefully this make sense now. Thanks heaps

• Wireframe mock-up software

  - by Dave Jarvis

  Requirements Looking for wireframe mock-up software for web apps with the following constraints: Desktop application (supports Linux) (can be online) Export all pages to separate image files (PNG or SVG preferred) Template for all pages Drag and drop standard HTML widgets for <forms> Tabbed panels (that allow content on the different tabs) Shuttle controls Saves in an XML format (XSLT could convert to HTML) Widget alignment and resizing (relative to other widgets) Under $100.00 USD Examples That come close: Cacoo - Not a desktop application; does not have a true tabbed panel widget Pencil - Export feature has serious bugs (missing text); no template? Balsamiq - Installation proved cantankerous on Linux (due to Adobe AIR) Mockingbird - No shuttle controls; no auto-resize of widgets Pencil & paper - Not a good look for a formal document presented to clients Any others that meet the requirements?

• Properly using subprocess.PIPE in python?

  - by Gordon Fontenot

  I'm trying to use subprocess.Popen to construct a sequence to grab the duration of a video file. I've been searching for 3 days, and can't find any reason online as to why this code isn't working, but it keeps giving me a blank result: import sys import os import subprocess def main(): the_file = "/Volumes/Footage/Acura/MDX/2001/Crash Test/01 Acura MDX Front Crash.mov" ffmpeg = subprocess.Popen(['/opt/local/bin/ffmpeg', '-i', the_file], stdout = subprocess.PIPE, ) grep = subprocess.Popen(['grep', 'Duration'], stdin = subprocess.PIPE, stdout = subprocess.PIPE, ) cut = subprocess.Popen(['cut', '-d', ' ', '-f', '4'], stdin = subprocess.PIPE, stdout = subprocess.PIPE, ) sed = subprocess.Popen(['sed', 's/,//'], stdin = subprocess.PIPE, stdout = subprocess.PIPE, ) duration = sed.communicate() print duration if __name__ == '__main__': main()

• Java Speech Example: Encode, Stream, Decode, Play

  - by Dewayne

  I have been trying to find an example of this that I could use for a couple years, I'm ashamed to admit. I would like to see a working, compileable example (most that I find online don't compile or don't actually work) of reading from the microphone, encoding the voice data in a speech-friendly encoding such as Speex, and streaming that information in real time to a Decoder which then plays the audio. I suppose this example would simply echo what is said. I would like to ultimately use this to learn to make an audio mixing chat server.

• How can we calculate sea distances using waypoints ?

  - by Ashish Ranpara

  Hi Friends, I have one query in which I really stuck at that. I have port database with waypoints and also routing points which I need to use in distance calculation between two ports. I have done lots of R&D to find formula which gives me distance between two points. I also need shortest route which is possible. I have reviewed online tools which allow user to calculate the distance. But I want to do the same at my own. I have reviewed Port World Distance Calculator. I reviewed the Great Circle formula to achieve that but I don't know that how we avoid landscapes in sea distance and in which direction I need to find distance for second port.

• Return Selected Phone Address from iPhone Address Book

  - by Ali

  Hey, I found a tutorial online that extends that Apple QuickStart Application which is the basic Address Book Application and another that returns the first phone number regardless of what phone number was clicked. I want to display only the selected phone number in the label. The label is called phoneNumber: - (BOOL)peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{ ABMutableMultiValueRef phoneMulti = ABRecordCopyValue(person, kABPersonPhoneProperty); NSMutableArray *phones = [[NSMutableArray alloc] init]; int i; for (i = 0; i < ABMultiValueGetCount(phoneMulti); i++) { NSString *aPhone = [(NSString*)ABMultiValueCopyValueAtIndex(phoneMulti, i)autorelease]; [phones addObject:aPhone]; } NSString *mobileNo = [phones objectAtIndex:0]; self.phoneNumber.text = phones; [self dismissModalViewControllerAnimated:YES]; return NO; } How do I ensure that the label is the one selected by the user and not just the first array entry(or any other array entry i code in) Thanks

• How do I get preg replace to work when the url contains a hashtag

  - by Steven

  I found a function online for turning a url within a string into a clickable link. However, when the url contains a hashtag it doesn't work. eg. http://www.bbc.co.uk/radio1/photos/fearnecotton/5759/1#gallery5759 Here's the part of the function concerned: $ret = preg_replace( "#(^|[\n ])([\w]+?://[\w]+[^ \"\n\r\t< ]*)#", "\\1<a href=\"\\2\" target=\"_blank\">\\2</a>", $ret ); $ret = preg_replace( "#(^|[\n ])((www|ftp)\.[^ \"\t\n\r< ]*)#", "\\1<a href=\"http://\\2\" target=\"_blank\">\\2</a>", $ret ); Any ideas? thanks

• How to void authorized transaction in authorize.net gateway using ActiveMerchant

  - by m7d

  Goal: Only have successful purchases show up on a customer's billing statement. I don't want declined authorizations showing up on their billing statement (as seen in an online banking system) as pending. A customer often will accidentally input an incorrect billing address, for example, followed by a correct one. Together, the two attempts, one successful and one not both show up on their billing statement as pending prior to settlement. This can scare the customer as it looks potentially like they will be charged twice. Details: When I do an AUTH_CAPTURE (via ActiveMerchant's purchase) or an AUTH (via ActiveMerchant's authorize) which is declined and subsequently want to void that authorization (via ActiveMerchant's void) so as not to have it appear on a customer's billing statement as pending (even though it will settle out after a few days), the gateway can't find the transaction to void using the authorization code returned from the authorization or capture method calls on the gateway. This is specific to the authorize.net AIM gateway. Please advise. Thanks!

• Custom message headers in WCF on Mono

  - by TheNextman

  I'm making WCF calls from a Mono client running on Ubuntu (Mono 2.6). I can't seem to add a custom header to my messages. I have tried two different ways: Using a [MessageContract] and [MessageHeader] attributes on a custom class Adding the header to the outgoing messages programmatically, e.g. MessageHeader mhg = new MessageHeader("test"); MessageHeader untyped = mhg.GetUntypedHeader("token", "ns"); OperationContext.Current.OutgoingMessageHeaders.Add(untyped); The header is not there when the call reaches the server! It's always null. Note that both methods work fine running on .NET in Windows. Also note that the message body gets through just fine on Mono. I see some references online that suggest this should work: http://forums.monotouch.net/yaf_postsm1692.aspx https://bugzilla.novell.com/show_bug.cgi?id=551745 Also - the Mono status page shows that all the MessageHeader stuff is fully implemented... Anyone had luck with this? Thanks in advance, Richard

• iPhone Developer Program - Help?

  - by Cal S

  Hi, I just signed up for the iPhone Developer Program (the $99 one), I filled it all out, was directed to the store and completed the purchase. However, when I go to the member center it says I have not completed the purchase: Your Developer Program Enrollment Status: Once you've completed your purchase, you will receive an Order Acknowledgement email from the Apple Online Store and an Activation email within 24 hours from Apple Developer Support. The email from Apple Developer Support will contain information on how to access the resources of your Program. With a link directing me to a page that adds the program to my cart in the Apple store. (A process I have already been through with a success message at the end) Is this what has happened to everyone else? Aren't I supposed to receive an email from Apple at least confirming the purchase? I have received nothing. Thanks a lot.

• Flash / actionscript 3 sound delay.

  - by Ole

  Hey. Im working on a flash project where I am loading multiple sounds from external files. The problem is that when I play them within my project there is a small delay from when they should be played until they are actually playing. My sounds are very short and are loaded before the project is actually using them. I have looked up the problem online and it looks like the problem is not something that is only happening for me. But, non of the resources I found had any clear ways of fixing this. Some resources say that you can fix this my constantly having a sound playing in the background. I have that but it does not help. I have also looked at the actual sound file in a sound tool and there is a small delay before the sound starts, but it is very very small and should not result in the delay im seeing in my flash project. Does anyone know of a good way to fix it?

• What is Google Docs' SLA?

  - by Walter White

  Hi all, I am evaluating online storage and for me, that means either Amazon S3 or Google Docs. Amazon very clearly posts there reliability and SLA: http://aws.amazon.com/s3/#protecting Their rates are obviously higher than Google's, but it is really hard to compare without having an SLA. Does anyone know what Google's commitment is for reliability? Is it 99.99% for data, is there anyway to make that more durable? I have to ask too, wouldn't google docs at least be inheritently more reliable than a hard drive? Thanks, Walter

• Programmatically modifying an embedded resource before registering/referencing it on the page

  - by Jimock

  Hi All, Firstly, "Modifying" may be the wrong term, I see a few people have posted online just asking whether they can actually modify an embedded resource. What I am wanting to to, is use a resource in my assembly as a kind of template which I would do a find and replace on before registering it on the page - is this possible? For example; say I have a few lines of jQuery as an embedded resource in my assembly and in this script I am referencing a CSS class name that can be set by the front-end programmer. Since I do not know what the CSS class will be until implementation, is there a way of going through the embedded resource and replacing, say, $myclass$ with ThisClassName. Any help would be appreciated, if it's not possible then at least tell me so I can stop chasing my tail. Cheers, James

• Programmatically Setting Text Shadow Properties

  - by Ben Gribaudo

  Hello, PowerPoint has two kinds of shadows--shape and text. Shape shadows may be set by right-clicking on a shape (including a text box), choosing Format Text, then selecting Shadow or using VBA via the Shadow property on each shape: For Each Slide In ActivePresentation.Slides For Each Shape In Slide.Shapes Shape.Shadow.Size = 100 'etc Next Next How do I set text shadow's properties using VBA? In the UI, these may be accessed by right-clicking on text, choosing Format Text Effect, then selecting Shadow. I've done a bit of digging online and have been unable to find where these properties may be accessed via PowerPoint's VBA API. Thank you, Ben

• How to sync iPhone and Mac CoreData objects through bonjour?

  - by monotreme

  I know similar questions have been asked before. I'm using the Sync Demo app I found online here, which uses Picture Sharing as a guide. I've integrated it into my desktop and iphone apps and have the connection working, but am clueless as to how to actually sync my objects. Is it as simple as if ([iphone Object] != [desktop object]) { //merge the two } I have the exact same object model used, I just basically want to know how to check if there are differences, and copy the ones that are different over. Anyone know of any sample code anywhere that would show this? Thanks so much.

• Distance by sea calculator, intermediate coordinates?

  - by Lucian2k

  How do I calculate distance between 2 coordinates by sea? I also want to be able to draw a route between the two coordinates. Only solution I found so far is to split a map into pixels, identify each pixel as LAND or SEA and then try to find the path using A* algorithm. Then transform pixels to relative coordinates. There are some software packages I could buy but none have online extensions. A service that calculates distances between sea ports and plots the path on a map is searates.com

• Using a priority queue in Java

  - by Bharat

  Forgive me if this is a tried question, but I'm having a little difficulty figuring it out. I currently have a class Node, and each 'node' is a square in a maze. I'm trying to implement the A* algorithm, so each of these nodes will have an f-cost (int) data member inside of it. I was wondering if there's a way that I can create a priority queue of these nodes, and set up the f-cost variable as the comparator? I've looked at examples online, but all I can find are String priority queues. Can I implement Comparator for the Node class? Would this allow me to access the data member stored inside it? Many Thanks!

• MTU mismatch between GetIfEntry and netsh

  - by ChrisJ

  I'm working on pseudo-transport layer software that runs over UDP, providing reliable connection-oriented transmission, as an alternative to TCP. In order to maximize network efficiency, we query the MTU of the "best" network adapter upon initialization. MIB_IFROW row = {0}; row.dwIndex = dwBestIfIndex; dwRes = GetIfEntry(&row); Searching online I found that you can use the following netsh commands to query for this same value, from a command prompt (not a C++ API) netsh interface ipv4 show interfaces netsh interface ipv4 show subinterfaces The troubling issue is that while row.dwMtu may be set to 1500, snooping the network traffic on the sending laptop shows that our packets are fragmented into 1300 byte packets. netsh also reports that the MTU is 1300. Clearly the value reported by netsh command is the actual used values. Anyone know what API I can call to get the same values as netsh?

• Does Google index HTTPS ASP.NET pages?

  - by ncakmak

  I have an online application that all of its pages use HTTPS. I have 3 questions: Does Google index HTTPS pages? I have a password protected single ASP.NET page (using HTTPS). Password protection is basically achieved by a Session object. When the correct password is entered, it hides the login panel and displays the same page which has a sensitive data. Is this page indexed by Google? I have a Secure folder that I implemented Forms Authentication. All pages in folder use HTTPS as well. Are the pages in this folder indexed by Google? Thank you for your help, Niyazi

• Why is Visual Studio 2008 stuck in debug mode when compiling

  - by Mark

  I have a .NET project that for some reason gets stuck in debug mode. I've changed the compile mode from debug to release in the toolbar, but my project ends up in the debug directory anyway. Seems like VS is not updating the SLN file or something. Please help! The reason I am asking about this is because it seems that there are weak references "ENCList" clogging up memory when my program runs, and they seem to be created when .NET apps are compiled in debug (or so says other sources I've found online). -Mark

• Can someone recommend a bells and whistles CSS framework?

  - by Ali A

  I am looking for a bells and whistles CSS framework. I have found a number online that deal with "grids", and some that deal with "typography" and others that deal with "resetting". What I have not found is something that will give my web applications a consistent reusable style or theme. I guess it would have to have a number of predefined elements that do things, for example: div.boxed {...} And then a number of themes or plugins that provide these in a consistent way. Javascript toolkits like ExtJS, YUI, and also GWT have their own skinability, and I guess this is the featureset that I want, but independent of any Javascript library. (Open source would be best, but we don't mind paying) Edit: 5 good answers, but I have seen all those frameworks, and they are not enough of what I am looking for. Perhaps what I am looking for doesn't exist. Or I haven't explained properly. I will give them a good going over and see.
