• Advice for Architecture Design Logic for software application

  - by Prasad

  Hi, I have a framework of basic to complex set of objects/classes (C++) running into around 500. With some rules and regulations - all these objects can communicate with each other and hence can cover most of the common queries in the domain. My Dream: I want to provide these objects as icons/glyphs (as I learnt recently) on a workspace. All these objects can be dragged/dropped into the workspace. They have to communicate only through their methods(interface) and in addition to few iterative and conditional statements. All these objects are arranged finally to execute a protocol/workflow/dataflow/process. After drawing the flow, the user clicks the Execute/run button. All the user interaction should be multi-touch enabled. The best way to show my dream is : Jeff Han's Multitouch Video. consider Jeff is playing with my objects instead of the google maps. :-) it should be like playing a jigsaw puzzle. Objective: how can I achieve the following while working on this final product: a) the development should be flexible to enable provision for web services b) the development should enable easy web application development c) The development should enable client-server architecture - d) further it should also enable mouse based drag/drop desktop application like Adobe programs etc. I mean to say: I want to economize on investments. Now I list my efforts till now in design : a) Created an Editor (VB) where the user writes (manually) the object / class code b) On Run/Execute, the code is copied into a main() function and passed to interpreter. c) Catch the output and show it in the console. The interpreter can be separated to become a server and the Editor can become the client. This needs lot of standard client-server architecture work. But some how I am not comfortable in the tightness of this system. Without interpreter is there much faster and better embeddable solution to this? - other than writing a special compiler for these objects. Recently learned about AXIS-C++ can help me - looks like - a friend suggested. Is that the way to go ? Here are my questions: (pl. consider me a self taught programmer and NOT my domain) a) From the stage of C++ objects to multi-touch product, how can I make sure I will develop the parallel product/service models as well.? What should be architecture aspects I should consider ? b) What technologies are best suited for this? c) If I am thinking of moving to Cloud Computing, how difficult/ how redundant / how unnecessary my efforts will be ? d) How much time in months would it take to get the first beta ? I take the liberty to ask if any of the experts here are interested in this project, please email me: [email protected] Thank you for any help. Looking forward.

• Free for personal use license?

  - by Lance May

  I'm trying desperately to find a software licensing model that would allow me to make my product completely open to the public domain for personal use/modification, but would be able to be sold commercially. I know such a beast exists, and I'm sure in many flavors. I just can't find it. ;( What I'm hoping for is a way to allow people the opportunity to benefit from the product in an "open source" fashion, while still allowing me to have a revenue on it to be able to continue development full time. Thanks much in advance.

• controlling if exceptions are swallowed by a static boolean

  - by sandis

  So we are a few guys developing this product that is communicating with a really unstable server. It often returns very strange and corrupt data. During testing we want the resulting crashes to be loud, so we discover them. But every other day we need to demonstrate our product for a potential customer. To the customer the errors will go undiscovered if we just swallow them. I am thinking about implementing something like this around all server communication to quickly switch between swallowing exceptions and crashing: try { apiCall(); } catch (Exception e) { if(!SWALLOW_EXCEPTION) { throw e; } } Is this an awesome idea, or can it be done in a better way?

• integrating django-paypal

  - by ramdaz

  Hi I am trying to integrate Django-Paypal onto a site, where once the customer makes a payment I need to send a dynamic URL from which the user can download some specific information. I am registering all users to a URL which allows them to buy the document. The URL which can only be accessed by a registered user with a verified email ids using django-registration, allows the user to connect to paypal and make payment. How do I capture the signal and verify which user has made the payment for which product he/she is purchased, based on this information 1) I need to know two information, which user made the payment, and for which product did he or she make the payment? 2) Only if I have these information can I send the right UR:L by email. Any help appreciated. I am not very sure how django-signals work. What all details does payment_was_successful signal return? I am using IPN

• asp.net free webcontrol to display crosstab or pivot reports with column and row grouping, subtotals

  - by dev-cu

  Hello, I want to develop some crosstab also know as pivot reports in Asp.net with x-axis and y-axis being dynamics, allowing grouping by row and column, for example: have products in y-axis and date in x-axis having in body number of sells of a given product in a given date, if date in x-axis are years, i want subtotals for each month for a product (row) and subtotals of sells of all products in date (column) I know there are products available to build reports, but i am using Mysql, so Reporting Service is not an option. It's not necessary for the client build additional reports, i think the simplest solution is having a control to display such information and not using crystal report (which is not free) or something more complex, i want to know if is there an available free control to reach my goal. Well, does anybody know a control or have a different idea, thanks in advance.

  - by Gleeb

• C# HttpRequest - Accessing hashtags in url

  - by CloudyOne

  Unfortunately because of the wide use of the word "hashtag" and "httprequest" i couldn't find any search results that gave me an answer on whether something like this is even possible. If i have a url like this: /Orders/Product#12345 The HttpRequest class shows me that the FilePath, RawUrl, and all other members that show the url as /Orders/Product It just gets rid of the hashtag, and i can't find a place to view it. Is there any way for me to be able to see what hashtag is on the end of the URL from the codebehind? I know i could easily make this a QueryString parameter, but i like the way this looks better, so if there's a way to do it, i'd like to find out what it is :) Thanks in advance!

• Choice of primary index for mysql innoDB

  - by Saif Bechan

  I have an auction website where users can place a bid on a product. Now i have a primary index on the bid table for easy access of the last places bid on the product. This index is just a unique auto incrementing value. During the week this number becomes huge!! I was wondering if this is a good setup for the primary key in an innoDB table. The bids table exist of the following important fields: table: bids fields: user_id,product_id,bid So what i want to do is make the primary of these 3 fields combined. Is this a good idea or is this just too much for innoDB keys.

• JNI call to Intel or PPC arch jnilib function differs

  - by vinzenzweber

  I am making a call from within Java to a jnilib function and get different logs on PPC and Intel. My function definitions are as follows: private native int initHandler(long vendorID, long productID); JNIEXPORT jint JNICALL Java_com_sue_protocol_SerialPortObserverThread_initHandler( JNIEnv *env, jobject obj, jlong usbVendor, jlong usbProduct) When initHandler() is called, the logs differ on the platforms: Mac OS X/10.5.8/ppc, Java 1.5.0_22 Looking for devices matching vendor ID=0 and product ID=7982. Mac OS X/10.6.3/x86_64, Java 1.6.0_17 Looking for devices matching vendor ID=7982 and product ID=10. The sample source for this project can be found on http://github.com/vinzenzweber/USBEventHandler What do I need to do to get the JNI call right on ALL platforms?

• How can I authenticate when using the Bugzilla Perl API in a script?

  - by Allan Anderson

  Working from the Bugzilla API, I've written a quick Perl script to clone a Bugzilla Product (recreating all the Components under their new Product). The Bugzilla Perl API is quite easy to use from the command line. I could have just worked on the database directly, but I wanted a longer-term solution. Another option was the webservice, but I thought I'd try using the API directly this time. The one problem I'm running into is authenticating as my Bz admin user so I can create the new components. Looking at Bugzilla's Bugzilla.pm file, I see that they just run login() from a Bugzilla::Auth object. I'm not sure how to get the username and password in there. I suppose I could just add the script to the Bugzilla admin interface... Can any of you point me in the right direction?

• How to join data frames in R (inner, outer, left, right)?

• how to get SSRS 2008 R2 to export/render in Excel 2007 format?

  - by James Manning

  I have a report that has ~1k columns and ~17k rows and I'm trying to render it to Excel 2007 with SSRS 2008 R2 Nov CTP. SSRS team members have mentioned in multiple places that Excel 2007 format is included in 2008 R2, for instance: http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/69545568-73cb-4f4c-8f35-44472ba6d013 Now, it's certainly possible that it just hasn't made it into the product yet (at least as of Nov CTP), and if that's the case, that would be good to know, too (and ideally when it would be in the product). The repro report and data (along with attempts showing the existing interface still does Excel 2003 format) are attached to the bottom of this blog post, FWIW: http://cid-456117cf53a42144.spaces.live.com/default.aspx

• rundll32.exe constantly running taking up resources slowing down my Win 7 computer

  - by Joe Fletcher

  Over the past week, my Windows 7 Home Premium computer (8gb RAM, 64bit) has been running slowly. When I look at my processes, there are always 2 rundll32.exe's running taking up 3 & 25% CPU power, memory slowly creeping upwards from around 115mb to 160mb each in the time it has taken me to right this message, sometimes popping upt o 300mb and back down. Svchost.exe is at 260mb. When I end those processes, everything returns to snappiness. I recently did some Windows Updates, and I think it was around the time my computer started acting slowly, but I can't remember if it was before or after the updates that things started running slowly. Last night I ccleaned & defrag'ed. How can I diagnose what's causing the slowness?

• Model Binding an IList of selected items only

  - by jeef3

  I have an action method setup: public ActionResult Delete(IList<Product> products) And a table of products in my view. I have got Model Binding working so that on submit I can populate the products list. But I would like to populate it with only the products that are selected via a checkbox. I think I could do it by changing the action method to this: public ActionResult Delete(IList<Product> products, IList<int> toDelete) And passing the list of check boxes to the toDelete but I would really like to avoid changing the method signature if possible. Is there a way to pass only the selected items? Or am I going to have to write a custom ModelBinder?

• Authentication for SaaS

  - by josh

  What would be recommended as an authentication solution for a Software-as-a-service product? Specifically, my product would have clients that would typically have low information technology skills, potentially not even having an IT department within their organization. I would still like to have my application authenticate against their internal directory service (eDirectory, Active Directory, etc.). I don't want them, however, to have to open/forward ports (for instance, opening up port 636 so I can do LDAPS binds directly to their directory service). One idea I had was to have an application installed on a server within their organization's network that would backconnect to my service. This would be a persistant socket. When I need to authenticate a user, I send the credentials via the socket (encrypted) - the application then performs a bind/whatever to authenticate against the directory service and replies with OK/FAIL. What would you suggest? My goal here is to essentially have the client install an application within their network, with very little configuration or intervention.
