  • Master report and subreport communication

    - by Dave Jarvis
    How do you determine whether the content for the detail page being displayed is filled by a specific subreport? For example, consider two subreports on the same master report, using different detail bands: Detail 1 Detail 2 The header on the master report should show certain fields on pages where the subreport in the Detail 2 band is printed. A Return Value from the subreport in the Detail 2 band only seems to be set after the report has finished, even though the Reset type for the variable (in both the master and the subreport) is set to Page. (Setting it to Report also does not help.)

  • measuring performance - using real clicks vs "ab" command

    - by shanyu
    I have a web site in closed beta, developed in Django, runs with Mysql on Debian. In the last few days, the main page has been showing a slowdown. For every ten clicks, one or two receives extremely slow response (10 secs or more), others are as fast as they used to be. When I was searching for the problem, I ran into this issue that I couldn't grasp: top command shows that when I request the main page, mysql shoots up to 90% - 100% cpu usage. I get the page just as the cpu use gets back to normal. So, I thought, it is db. Then I called ab with parameters -n 1000 -c 5, I got decent performance, about 100 pages per second, just as it was before the slowdown. I would imagine a worse performance as 10-20% of requests take 10 secs to load. Is this conflict between ab and "real" clicks normal, or am I using ab in a wrong configuration?

  • Why is activeX failing to create an object from a Labview executable?

    - by user360734
    Here is my scenario. I am using Quicktest Pro (VB) to create an ActiveX object from a Labview VI that I built into an executable. In the build specs of the VI I have enabled ActiveX server option (ActiveX server name: "MyLabviewProgram") and in the VI ToolsOptionsVI Server: Configuration the ActiveX box is checked. So in QTP my code is: Set IvApp = CreateObject("MyLabviewProgram.Application") Set Vi = IvApp.getVIReference("MyLabviewVI.vi") Vi.Call ParamNames, ParamVals Upon running this I get a Run Error on the first line: ActiveX component can't create object: 'MyLabviewProgram.Application' I am having trouble figuring out why it errors. From National Instruments website they have a step in on one of their community pages about "LabVIEW Executable Used as ActiveX Server". The step is after building the EXE, 5. Run the EXE at least once on the target to activate the .TLB file. I've run the executable but not sure what they mean by on the target. Does anyone have a suggestion on what I need to do to get this working?

  • ASP.NET OutPutCache VaryByParam and VaryByHeader with AJAX

    - by DennyDotNet
    I'm trying to do some caching using VaryByParam AND VaryByHeader. When an AJAX request comes in I return a partial XHTML. When a regular request comes in I send the partial XHTML page with header / footer. I tried to cache the page by doing: [OutputCache( Duration = 5, VaryByParam = "nickname,page", VaryByHeader = "X-Requested-With" )] However this doesn't work... if I do a regular request first then run the AJAX call I get the full cached page instead of the partial and vice-versa. Seems like VaryByHeader is being ignored. Is it because X-Requested-With is omitted on normal requests? Or perhaps it's doing VaryByParam OR VaryByHeader? My obvious way around this is for AJAX requests to call a different method which only returns partial pages, however I'd like to avoid that if possible. I'm using ASP.NET MVC 1.0 with the OutputCacheAttribute.

  • Linking to external file in Ruby on Rails

    - by Maestro1024
    Linking to external file in Ruby on Rails I have a file I want to share as a link in my rails app. I create a link to it in the .erb file like this <li><a href="somefile.pdf">Some File</a> </li> When I select the link I get the following error. Routing Error No route matches "/pages/somefile.pdf" with {:method=:get} Do I really need a route for this? I really just want the save as dialog to popup. Just a link to a file that the user can open or download. What is the rails way to do this (rails newbie here)?

  • What are the lesser known but cool data structures ?

    - by f3lix
    There a some data structures around that are really cool but are unknown to most programmers. Which are they? Everybody knows linked lists, binary trees, and hashes, but what about Skip lists, Bloom filters for example. I would like to know more data structures that are not so common, but are worth knowing because they rely on great ideas and enrich a programmer's tool box. PS: I am also interested on techniques like Dancing links which make interesting use of the properties of a common data structure. EDIT: Please try to include links to pages describing the data structures in more detail. Also, try to add a couple of words on why a data structures is cool (as Jonas Kölker already pointed out). Also, try to provide one data-structure per answer. This will allow the better data structures to float to the top based on their votes alone.

  • (php) how to properly 'save' info in forms completed thus far

    - by hatorade
    So i have a form that on paper is 40 pages long. I was going to take the natural sections of this form, and make separate html forms for each section, with the idea that on the first page there would be a first form, then you hit 'Continue to next section' which essentially is the 'submit' button, which moves the user to section two, etc, until they hit the last section. i am not actually storing the results of the form in a database, but rather sending an email. the idea then is to store the separate form answers (one html form per section in the real form) as arrays or objects in the session, so that if they go back to a section in the form, it repopulates the values they entered since they are stored in the session. the result would be an array in the session storing the results for each of my forms, and i have one form for each section. my question is: is it secure to temporarily store things like SSNs or driver's license numbers as session variables? why or why not?

  • Silverlight4 Printing Question

    - by hallgato.attila
    Hello everyone! I'm having a problem with printing. Is it possible to print a (customized) DataGrid which doesn't fit the page? a) Using a ViewBox to make it fit one page. My problem here is that I can get the PrintableArea.Width and PrintableArea.Height in the PrintPage EventHandler, from the PrintPageEventArgs, but in that Event Handler I can't set the size of an UIElement before it gets printed. b) Multiple pages. Is it possible somehow to print the whole DataGrid, even the parts which are not visible (don't fit the page) and to somehow make the PrintableArea only a part of the DataGrid?

    Hey everyone, Just moved to shared hosting on GoDaddy and Im trying to get my .htaccess rules working. Heres what I have: ErrorDocument 404 /error.php Options FollowSymLinks RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} ^www\.mydomain\.org$ RewriteRule ^(.*)$ http://mydomain.org/$1 [R=301,L] RewriteRule ^view/(\w+)$ viewitem.php?itemid=$1 [R=301,L] RewriteRule ^category/(\w+)$ viewcategory.php?tag=$1 [R=301,L] RewriteRule ^faq$ faq.php RewriteRule ^about$ about.php RewriteRule ^contact$ contact.php RewriteRule ^submit$ submit.php RewriteRule ^contactmsg$ handler-contact.php All the pages @ the root of the domain seem to be working i.e mydomain.org/faq, mydomain.org/about are working. But whenever I try mydomain.org/category/somecategory, I get a 404. How can I fix my .htaccess to obey these rules that are more than 1 level deep? Thanks,

  • how to setup rails Authenticity Token to work with multiple domains?

    - by bwizzy
    I'm building an app that uses subdomains as account handles (myaccount.domain.com) and I have my sessions configured to work across the sub-domains like so: config.action_controller.session = {:domain => '.domain.com'} In addition to the subdomain a user can input a real domain name when they are creating their account. My Nginx config is setup to watch for *.com *.net etc, and this is working to serve out the pages. The problem comes when a site visitor submits a comment form on a custom domain that was input by the user. The code is throwing an "Invalid AuthenticityToken" exception. I'm 99% sure this is because the domain the user is on isn't specified as the domain in the config.action_controller.session. Thus the authenticity token isn't getting matched up because Rails can't find their session. So, the question is: Can you set config.action_controller.session to more than 1 domain, and if so can you add / remove from that value at runtime without restarting the app?

  • PyDev and Django: how to restart dev server?

    - by Rosarch
    I'm new to Django. I think I'm making a simple mistake. I launched the dev server with Pydev: RClick on project Django Custom command runserver The server came up, and everything was great. But now I'm trying to stop it, and can't figure out how. I stopped the process in the PyDev console, and closed Eclipse, but web pages are still being served from http://127.0.0.1:8000. I launched and quit the server from the command line normally: python manage.py runserver But the server is still up. What am I doing wrong here?

  • Programmaticaly grabbing text from a web page that is dynamically generated.

    - by bstullkid
    There is a website I am trying to pull information from in perl, however the section of the page I need is being generated using javascript so all you see in the source is <div id="results"></div> I need to somehow pull out the contents of that div and save it to a file using perl/proxies/whatever. e.g. the information I want to save would be document.getElementById('results').innerHTML; I am not sure if this is possible or if anyone had any ideas or a way to do this. I was using a lynx source dump for other pages but since I cant straight forward screen scrape this page I came here to ask about it! If anyone is interested, the page is http://downloadcenter.trendmicro.com/index.php?clk=left_nav&clkval=pattern_file&regs=NABU and the info I am trying to get is the row about the ConsumerOPR

  • How do I manage report paging in HTML?

    - by ProfK
    I have a small, custom crafted HTML report, not using any reporting engine, for various reasons. The client's layout is quite handy, as each report section fits on its own page, so I have one div for each page, with a CSS class of .page, setting A4 dimensions with margin, and a header image. Each 'page' also has a small header table just under the header image, and a section heading label. Now, some sections threaten to overflow their page, and I'm looking at ways to handle this. One clumsy approach is to include a second page for those sections that might overflow, and delete these pages before rendering if they are empty. If I do this, how can I 'tell' content on one page to overflow into the next page? The report is finished and a once off effort, so I'm not keen to convert it into a SSRS or Telerik report just to achieve this paging.

  • IE8 blocking JavaScript Cookies

    - by ossreleasefeed
    Hey there folks, Here is one that is throwing me for a loop. I am trying to set a simple cookie that has one name:value pair on IE8. Tested on FF and it works fine. IE8 keeps blocking it. I have read about the P3P stuff and created a basic P3P doc, no errors reported by the IBM tool, and added the following on all pages: <meta http-equiv="P3P" CP="CAO DSP COR PSDa CONi TELi OUR STP COM NAV"><link rel="P3Pv1" href="/w3c/p3p.xml"></link> The code I use to set the cookie is as follows: function setCompatibilityCookie(c_name, value, expiredays) { var exdate = new Date(); exdate.setDate(exdate.getDate() + expiredays); document.cookie= c_name + "=" + escape(value) + ((expiredays==null) ? "" : ";expires=" + exdate.toUTCString());} Any ideas why IE8 keeps blocking me from setting this cookie? Thank you, Schalk

  • Easy Way for Non-Nerd to Manage Simple Site?

    - by Mark Evans
    Hi I'm not sure if this is an appropriate question for StackOverflow. I have a friend show wants a simple "Brochure Ware" web site. I could make it for him but it would be better if he could manage it himself. Are there any services out there that allow a non-technical person to create and maintain a very simple site? I'm thinking just a few pages - contact, about, home with some photos and general info. He also wants to sell some stuff but I'm going to suggest he does this using EBay but the web site would be a handy reference for potential customers who want to know more about him and his services. Thanks a lot! Cheers Mark

  • How to lock non-browser clients from submitting a request?

    - by Thomas Kohl
    I want to block non-browser clients from accessing certain pages / successfully making a request. The website content is served to authenticated users. What happens is that our user gives his credentials to our website to 3rd party - it can be another website or a mobile application - that performs requests on his behalf. Say there is a form that the user fills out and sends a message. Can I protect this form so that the server processing the submission can tell whether the user has submitted it directly from the browser or not? I don't want to use CAPTCHA for usability reasons. Can I do it with some javascript?

  • Specifying different page base classes for different directories in your web.config file

    - by gbinflames
    I have a website (coded in vb.net) with an "admin" section (the admin section being a folder in the actual site)... So in every page of the site I'm using my own custom class as the page base (which has been set in the web.config file) but I want to inherit from different class for the files in the "admin" folder... Is there any way to inherit different classes for pages in different folders using the web.config or some other equally as global method? (meaning some other way than inheriting on a per page basis.)

  • PHP: How To call Standard Library Functions

    - by Andi
    Hi, I'm starting with PHP for dynamic web pages. I have some libaries written in ANSI C for getting/setting parameters and other proprietary stuff. I wonder, is there a simple solution to use a wrapper inside PHP to call this funtions? Is there a already existing class/library? What would be the best practice to do this on my own? I don't want do make calls to external applications and use stdin/stdout! Is there a simple example available? I don't want to dig through the Zend documentation for now, I only need a feeling for the complexity. Thanks, kind regards, Andi

Code is not required just help with the SQL concept or math for it, would help me understand how to move it better...

  • Any good jQuery plugins to awesomify my pagination?

    - by marcgg
    I have a basic pagination system that looks something like that: First | < Previous | 1, 2, [3], 4, 5 ... 100, 101, 102 | Next > | Last Nothing fancy really. I am looking at various plugins to improve the way the user would browse this, but so far I haven't found anything really new or interesting except: http://tympanus.net/jPaginate/ : interesting way of browsing between pages but still very classical in the realization http://cpojer.net/Scripts/Pagination/ : totally new way of doing pagination, but the implementation isn't perfect and it's not really usable. Do you guys have ideas on how I could improve the way my users browse through navigation? Are there any good jQuery plugins out there already doing that?

  • Database indexes - what should they be

    - by WebweaverD
    Most of my database tables have a clear unique index through which lookups are done 90% of the time but I am a bit unsure on this one - I have a table which keeps track of user rating totals for items in my database, I now want to add another table, to track individual ratings with an ip address column to make sure no one can rate something twice. Since I can see this becoming a big, high use table it is important to optimize it correctly. (MYSQL table) This table will have the following fields: rating_id(always - unique), item_id (always - not unique), user_id (optional - not unique), ip_address (always - not unique), rating_value(always - not unique), has_review(bool) Now I envisions 90% the queries going something like this: When a user rates something - select where item_id = x and ip_address = y, (if rows = 0) insert rating When in user account pages - select where ip_address = x or username = y Now none of the fields searched on are unique, can I still use them as indexes (for example item _id and ip_address), can I have two indexes and will this still improve performance over a non indexed table?
