  • Querying a 3rd party website's database from my website

    - by Mong134
    The Goal: To retrieve information from a 3rd party database based off of a user's query on my ASP.NET website The Details: I need to be able to search 3rd-party websites for information relating to pharmaceutical drugs. Basically, here's what I've been tasked with: a user starts entering the name of a drug they're using in their experiments, and while they're typing a 3rd party website (e.g., here or here) is queried and suggestions are made based based off of what they've typed. Once they've made a selection, certain properties (molecular weight, chemical structure, etc) are retrieved from the 3rd party database and stored in our database. PharmaGKB.org's search bar is pretty much what I need to implement, but I need to access a 3rd party db. The site that I'm working on is ASP.NET/C#. The Problem: I don't really know where to start with this. There's a downloadable Perl example at the bottom of the page here, but it didn't really help me all that much. I'm at a loss as to how to implement this, or even find information about how to do it. The AJAX toolkit was suggested, but I'm not sure if that will solve the issue. JavaScript is also being considered, but again, I'm not sure if that will be sufficient, either. Perl Example Connection As a mentioned, here is a snippet from the Perl example given on the Pharmgkb.org site: my $call = SOAP::Lite -> readable (1) -> uri('SearchService') -> proxy('http://www.pharmgkb.org/services/SearchService') -> search ($ARGV[0]); However, I'm not sure how to implement this is C#/ASP.NET/JavaScript. There's a question on Stack Overflow about embedding Perl in C#, but it require a C wrapper as well, and I don't think that three languages is necessary or wise to solve this issue.

  • "A generic error occurred in GDI+" error while showing uploaded images

    - by Prasad
    i am using the following code to show the image that has been saved in my database from my asp.net mvc(C#) application:. public ActionResult GetSiteHeaderLogo() { SiteHeader _siteHeader = new SiteHeader(); Image imgImage = null; long userId = Utility.GetUserIdFromSession(); if (userId > 0) { _siteHeader = this.siteBLL.GetSiteHeaderLogo(userId); if (_siteHeader.Logo != null && _siteHeader.Logo.Length > 0) { byte[] _imageBytes = _siteHeader.Logo; if (_imageBytes != null) { using (System.IO.MemoryStream imageStream = new System.IO.MemoryStream(_imageBytes)) { imgImage = Image.FromStream(imageStream); } } string sFileExtension = _siteHeader.FileName.Substring(_siteHeader.FileName.IndexOf('.') + 1, _siteHeader.FileName.Length - (_siteHeader.FileName.IndexOf('.') + 1)); Response.ContentType = Utility.GetContentTypeByExtension(sFileExtension.ToLower()); Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.BufferOutput = false; if (imgImage != null) { ImageFormat _imageFormat = Utility.GetImageFormat(sFileExtension.ToLower()); imgImage.Save(Response.OutputStream, _imageFormat); imgImage.Dispose(); } } } return new EmptyResult(); } It works fine when i upload original image. But when i upload any downloaded images, it throws the following error: System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+. System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+. at System.Drawing.Image.Save(Stream stream, ImageCodecInfo encoder, EncoderParameters encoderParams) at System.Drawing.Image.Save(Stream stream, ImageFormat format) For. Ex: When i upload the original image, it shows as logo in my site and i downloaded that logo from the site and when i re-upload the same downloaded image, it throws the above error. It seems very weird to me and not able to find why its happening. Any ideas on this?

  • MySQL app with Cassandra in mind

    - by SODA
    I am planning to make a web app which will eventually use Cassandra. But now that I don't have it and don't have server(s) to run it from, I'd like to start by using MySQL. The question is, is it possible to structure data and queries in such a way that it would be fairly easy to later port it to Cassandra? Main idea, I guess, would be writing MySQL queries that would be possible to change to same Cassandra queries. Maybe you have a better suggestion?

  • Where to store application global variable?

    - by Shawn Mclean
    I'm using silverlight, project structure is similiar to any other .net app. I have a map control that I would like to store what mode it is in (either road or aerial) so that other controls can access this. Where do I put this enum variable, I plan to use 2 way binding on it so both are updated when either changes. Thanks.

  • Setup SVN/LAMP/Test Server/ on linux, where to start?

    - by John Isaacks
    I have a ubuntu machine I have setup. I installed apache2 and php5 on it. I can access the web server from other machines on the network via http://linux-server. I have subversion installed on it. I also have vsftpd installed on it so I can ftp to it from another computer on the network. Myself and other users currently use dreamweaver to checkin-checkout files directly from our live site to make changes. I want the connect to the linux server from pc. make the changes on the test server until ready and then pushed to the live site. I want to use subversion also into this workflow as well. but not sure what the best workflow is or how to set this up. I have no experience with linux, svn, or even using a test server, the checkin/out we are currently doing is the way I have always done it. I have hit many snags already just getting what I have setup because of my lack of knowledge in the area. Dreamweaver 5 has integration with subversion but I can't figure out how to get it to work. I want to setup and create the best workflow possible. I dont expect anyone to be able to give me an answer that will enlighten me enough to know everthing I need to know to do what I want to do (altough if possible that would be great) instead I am looking for maybe a knowledge path like answer. Like a general outline of what I need to do accompanied with links to learn how to do it. like read this book to learn linux, then read this article to learn svn, etc., then you should know what to do. I would be happy just getting it all setup, but I would like to know what I am actually doing while setting it up too.

  • VS2010 development web server does not use integrated-mode HTTP handlers/modules

    - by Domenic
    I am developing an ASP.NET MVC 2 web site, targeted for .NET Framework 4.0, using Visual Studio 2010. My web.config contains the following code: <system.webServer> <modules runAllManagedModulesForAllRequests="true"> <add name="XhtmlModule" type="DomenicDenicola.Website.XhtmlModule" /> </modules> <handlers> <add name="DotLess" type="dotless.Core.LessCssHttpHandler,dotless.Core" path="*.less" verb="*" /> </handlers> </system.webServer> When I use Build > Publish to put the web site on my local IIS7 instance, it works great. However, when I use Debug > Start Debugging, neither the HTTP handler nor module are executed on any requests. Strangely enough, when I put the handler and module <add /> tags back into <system.web /> under <httpHandlers /> and <httpModules />, they work. This seems to imply that the development web server is running in classic mode. How do I fix this?

  • Using jQuery to disable CSS inheritance

    - by Buzzedword
    Is there a way to use jQuery (or generic javascript) to disable CSS inheritance on a block level? For example, if I am pulling in an external resource via javascript, say pastie.org, they will have their own CSS that my CSS overrides. I would like to place the embed code into its own container that has CSS inheritance disabled. This is not my own CSS structure, so I can't rename IDs Classes or inline anything to make it work, the holy grail of inheritance blocking is my last resort.

  • Hibernate3: Self-Referencing Objects

    - by monojohnny
    Need some help on understanding how to do this; I'm going to be running recursive 'find' on a file system and I want to keep the information in a single DB table - with a self-referencing hierarchial structure: This is my DB Table structure I want to populate. DirObject Table: id int NOT NULL, name varchar(255) NOT NULL, parentid int NOT NULL); Here is the proposed Java Class I want to map (Fields only shown): public DirObject { int id; String name; DirObject parent; ... For the 'root' directory was going to use parentid=0; real ids will start at 1, and ideally I want hibernate to autogenerate the ids. Can somebody provide a suggested mapping file for this please; as a secondary question I thought about doing the Java Class like this instead: public DirObject { int id; String name; List<DirObject> subdirs; Could I use the same data model for either of these two methods ? (With a different mapping file of course). --- UPDATE: so I tried the mapping file suggested below (thanks!), repeated here for reference: <hibernate-mapping> <class name="my.proj.DirObject" table="category"> ... <set name="subDirs" lazy="true" inverse="true"> <key column="parentId"/> <one-to-many class="my.proj.DirObject"/> </set> <many-to-one name="parent" class="my.proj.DirObject" column="parentId" cascade="all" /> </class> ...and altered my Java class to have BOTH 'parentid' and 'getSubDirs' [returning a 'HashSet']. This appears to work - thanks, but this is the test code I used to drive this - I think I'm not doing something right here, because I thought Hibernate would take care of saving the subordinate objects in the Set without me having to do this explicitly ? DirObject dirobject=new DirObject(); dirobject.setName("/files"); dirobject.setParent(dirobject); DirObject d1, d2; d1=new DirObject(); d1.setName("subdir1"); d1.setParent(dirobject); d2=new DirObject(); d2.setName("subdir2"); d2.setParent(dirobject); HashSet<DirObject> subdirs=new HashSet<DirObject>(); subdirs.add(d1); subdirs.add(d2); dirobject.setSubdirs(subdirs); session.save(dirobject); session.save(d1); session.save(d2);

  • Should I use a resource loader for a SPA, or front-load everything?

    - by Shango
    I've been getting into Backbone.js lately and I'm enjoying it so far. All the examples tend to be simple to-do lists, so it's been a little difficult extrapolating code organization and file structure for a larger/more robust single page application. I've come to a crossroad: Should I use something like Yepnope.js to load models and views as I need them or, Combine and minify into fewer files and front-load it all. Some combination of both? Any advice would be appreciated!

  • response.write only working IE for ASP.NET

    - by slowlycooked
    I'm using uploadify (http://www.uploadify.com/) to upload video to my site then convert them into *.flv using ffmpeg and play preview. But it dosen't fully working with firefox, chrome or safari. uploadify provides a onComplete interface, so when the script (.ashx, .php) used on your site for saving uploaded files. you can use response.write("blabla") or (echo "blabla") to invoke the javascript function that registed as OnComplete. i have test with few video files like avi, mpg, mp4, they are less then 50mb,and they all worked with all 4 browsers. However, when i was trying to upload a 75mb mp4 file, it worked in IE, but didn't working in other three. I can see the .flv file has been create in the upload folder, i can see debug messsage output after response.write("blabla"), but the javascript function was not invoked. i.e. the preview didn't play. anyone knows why? is there a timeout or something on response.write so after a period of time it wont work? e.g. 75mb file took longer time to convert than other smaller size file i tried. thansk

  • Flex unit testing with ANT vs Flash Builder 4

    - by peterlindstrom21
    I have just tried setup unit testing in Flash Builder 4, and it working nicely. A setup of a parallel test source structure and using Flash Builder 4:s new TestCase and new TestSuite I was up and running with some testcases within minutes. But now I want to compile them from a ant flex task, the Flash Builder generates FlexUnitApplication.mxml and FlexUnitCompilerApplication.mxml. Is there a nice way to build the unit tests with ant using these? I cant find any sample where this is done.

  • White Screen of Death (WSOD) in Browser

    - by nickyt
    Here's the specs: ASP.NET 3.5 using ASP.NET AJAX AJAX Control Toolkit jQuery 1.3.2 web services IIS6 on Windows Server 2003 SP1 SP1 SQLServer 2005 SP3 Site is SSL Here's the problem: I'm getting the White Screen of Death (WSOD) in pretty much any browser (at least FireFox and IE 7/8). We have an application that uses one popup window for updating records. Most of the time when you click on the [Edit] button to edit a record, the popup window opens and loads the update page. However, after editing records for a while, all of a sudden the popup window will open, but it stays blank and just hangs. The URL is in the address bar. Loading up Fiddler I noticed that the request for the update page is never sent which leads me to believe it's some kind of lockup on the client-side. If I copy the same URL that's in the popup window into a new browser window, the page generally loads fine. Observations: - Since the request is never sent to the server, it's definitely something client-side - Only appears to happen when there is some semblance of traffic on the site which is weird because this appears to be contained within client-side code - There is a web service being called in the background every few seconds checking if the user is logged on, but this doesn't cause the freeze. I'm really at a loss here. I've googled WSOD but not much seems to appear related to my specific WSOD. Any ideas?

  • Supporting multiple instances of a plugin DLL with global data

    - by Bruno De Fraine
    Context: I converted a legacy standalone engine into a plugin component for a composition tool. Technically, this means that I compiled the engine code base to a C DLL which I invoke from a .NET wrapper using P/Invoke; the wrapper implements an interface defined by the composition tool. This works quite well, but now I receive the request to load multiple instances of the engine, for different projects. Since the engine keeps the project data in a set of global variables, and since the DLL with the engine code base is loaded only once, loading multiple projects means that the project data is overwritten. I can see a number of solutions, but they all have some disadvantages: You can create multiple DLLs with the same code, which are seen as different DLLs by Windows, so their code is not shared. Probably this already works if you have multiple copies of the engine DLL with different names. However, the engine is invoked from the wrapper using DllImport attributes and I think the name of the engine DLL needs to be known when compiling the wrapper. Obviously, if I have to compile different versions of the wrapper for each project, this is quite cumbersome. The engine could run as a separate process. This means that the wrapper would launch a separate process for the engine when it loads a project, and it would use some form of IPC to communicate with this process. While this is a relatively clean solution, it requires some effort to get working, I don't now which IPC technology would be best to set-up this kind of construction. There may also be a significant overhead of the communication: the engine needs to frequently exchange arrays of floating-point numbers. The engine could be adapted to support multiple projects. This means that the global variables should be put into a project structure, and every reference to the globals should be converted to a corresponding reference that is relative to a particular project. There are about 20-30 global variables, but as you can imagine, these global variables are referenced from all over the code base, so this conversion would need to be done in some automatic manner. A related problem is that you should be able to reference the "current" project structure in all places, but passing this along as an extra argument in each and every function signature is also cumbersome. Does there exist a technique (in C) to consider the current call stack and find the nearest enclosing instance of a relevant data value there? Can the stackoverflow community give some advice on these (or other) solutions?

  • Alternative to using c:out to prevent XSS

    - by lynxforest
    I'm working on preventing cross site scripting (XSS) in a Java, Spring based, Web application. I have already implemented a servlet filter similar to this example http://greatwebguy.com/programming/java/simple-cross-site-scripting-xss-servlet-filter/ which sanitizes all the input into the application. As an extra security measure I would like to also sanitize all output of the application in all JSPs. I have done some research to see how this could be done and found two complementary options. One of them is the use of Spring's defaultHtmlEscape attribute. This was very easy to implement (a few lines in web.xml), and it works great when your output is going through one of spring's tags (ie: message, or form tags). The other option I have found is to not directly use EL expressions such as ${...} and instead use <c:out value="${...}" /> That second approach works perfectly, however due to the size of the application I am working on (200+ JSP files). It is a very cumbersome task to have to replace all inappropriate uses of EL expressions with the c:out tag. Also it would become a cumbersome task in the future to make sure all developers stick to this convention of using the c:out tag (not to mention, how much more unreadable the code would be). Is there alternative way to escape the output of EL expressions that would require fewer code modifications? Thank you in advance.

    Hi SO community I have been issued a problem with security. A bank will not allow use of DLL's in the project. What sort of structure would be needed to allow DataAccess and or the use of external services (like an email client mailchimp, icontct). has anyone else encountered this sort of problem before? If they have how should the project be structured (.net 3.5+). Thanks, KJ

  • Sql Server Compact Edition version error.

    - by Tim
    I am working on .NET ClickOnce project that uses Sql Server 2005 Compact Edition to synchronize remote data through the use of a Merge replication. This application has been live for nearly a year now, and while we encounter occasional synchronization errors, things run quite smoothly for the most part. Yesterday a user reported an error that I have never seen before and have yet to find any information for online. Many users synchronize every night, and I haven't received error reports from anyone else, so this issue must be isolated to this particular user / client machine. Here are the full details of the error: -Error Code : 80004005 -Message : The message contains an unexpected replication operation code. The version of SQL Server Compact Edition Client Agent and SQL Server Compact Edition Server Agent should match. [ replication operation code = 31 ] -Minor Error : 28526 -Source : Microsoft SQL Server Compact Edition -Numeric Parameters : 31 One interesting thing that I've found is that his data does get synchronized to the server, so this error must occur after the upload completes. I have yet to determine whether or not changes at the server are still being downloaded to his subscription. Thinking that maybe there was some kind of version conflict going on, I had a remote desktop session with this user last night and uninstalled both the application and the SQL Server Compact Edition prerequisite, then reinstalled both from our ClickOnce publication site. I also removed his existing local database file so that upon synchronization, an entirely new subscription would be issued to him. Still his errors continue. I suppose the error may be somewhat general, and the text in the error message stating that the versions should match may not necessarily reflect the problem at hand. This site contains the only official reference to this error that I've been able to find, and it offers no more detail than the error message itself. Has anyone else encountered this error? Or at least know more about SQL Compact to have a better guess as to what is going on here? Any help / suggestions will be greatly appreciated!

  • Problem using unicode in URLs with cgi.PATH_INFO in ColdFusion

    - by Loftx
    Hi there, My ColdFusion (MX7) site has search functionality which appends the search term to the URL e.g. http://www.example.com/search.cfm/searchterm. The problem I'm running into is this is a multilingual site, so the search term may be in another language e.g. ??????? leading to a search URL such as http://www.example.com/search.cfm/??????? The problem is when I come to retrieve the search term from the URL. I'm using cgi.PATH_INFO to retrieve the path of the search page and the search term and extracting the search term from this e.g. /search.cfm/searchterm however, when unicode characters are used in the search they are converted to question marks e.g. /search.cfm/??????. These appear actual question marks, rather than the browser not being able to format unicode characters, or them being mangled on output. I can't find any information about whether ColdFusion supports unicode in the URL, or how I can go about resolving this and getting hold of the complete URL in some way - does anyone have any ideas? Cheers, Tom

  • How do I identify an ASP.NET MVC website?

    - by Alejandro
    I am trying to determine whether a company has websites built with ASP.NET MVC in their portfolio. Is there a reliable way of determining that without asking them assuming that I can visit the website in question in my browser? This might seem simple, but I wasn't able to find this information online. I would think that the lack of viewstate related stuff in the HTML source and the noun-verb URL structure would be good indicators. Are there any other indicators?

  • nginx 0.7.65 rewrite url with querystring problem?

    - by WisdomFusion
    Hi, all Recently, I altered my web server lighty to nginx. And now, Struggling with some problems. First, I have a site in nginx which only rewrites urls and redircts them to a new domain, and this site has exactly no file in its root directory. I put some rewrite rules (just string rules, no querystring) in my nginx.conf list 1 rewrite ^/index_([0-9]+)(.*)$ /forum-$1-1.html last; rewrite ^/dispbbs_([0-9]+)_([0-9]+)\.html$ /thread-$2-1-1.html last; Those rules work perfect till now. However, some rules that used to rewrite url with querystring do not work as hoped. list 2 location /index.asp { if ($arg_boardid ~ "^([0-9]+)") { rewrite ^ /forum-$arg_boardid-1.html break; } rewrite ^ /index.php break; } location /dispbbs.asp { rewrite ^ /thread-$arg_id-1-1.html break; } And, these rules are converted from rules under httpd server, list 3 ^/dispbbs\.asp\?boardID=([0-9]+)&ID=([0-9]+).*$ /thread-$2-1-1.html; ^/dispbbs\.asp\?(.*)&id=([0-9]+)(.*)$ /thread-$2-1-1.html; ^/index\.asp\?boardid=([0-9]+)(.*)$ /forum-$1-1.html; ^/index\.asp\?boardid=([0-9]+)$ /forum-$1-1.html; ^/index\.asp$ /index.php; So, what's the matter with rules listed in the list 2? and how could I make it woking.
