Can Use SSIS To Parse Data From Application Before Store In Db
Mar 29, 2011
Exploring the feasibility of something here... We have a UI page in the mvc3 web-application that the admin will use to upload a 'csv' file. Is it possible to have an SSIS package that will be called by the application..that will validate/transform all these data and store into db if its all valid or throw back error details to application if there are invalid data?
Just trying to leverage the capabilities of SSIS to do the parsing of file and transformation of data. If this is not possible, is there a better way?
update: yes, need to execute ssis on the fly.. and give back a message on the UI page. telling the'uploader' if his upload failed or not based on message that SSIS would give back to the application.
i am having a problem in executing the SSIS package through an asp.net application. i'm using c#. every time i run the package through web, i think the package is not disposed properly so until and unless i stop the application the package won't execute...i am not able to dispose or unload the package. i'm geeting errors like
'WebDev.WebServer.EXE' (Managed): Loaded 'C:WINDOWSassemblyGAC_32CustomMarshalers2.0.0.0__b03f5f7f11d50a3aCustomMarshalers.dll', Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled. The result of the expression ""EXEC " + @[User::vRowData]" on property "SqlStatementSource" cannot be written to the property.
The expression was evaluated, but cannot be set on the property. : Package Execution results: {0}
I occasionally get errors in my aspx files which are caused by problems with the designer file. When this happens I delete the designer file, right click on the aspx file and select "Convert to Web Application".
Usually regenerating the designer file works perfectly, however sometimes I get an error which simply says "Could not parse the file pathToFile.aspx". When this happens there are no useful errors displayed in the error panel which would indicate what the problem is. I got this error a little while ago, did some searching and found a blog which explains how to get round this problem. It suggests closing the file, cleaning the project, rebuilding then tring again. VS should now give you a more useful error message which pinpoints the problem. This has worked for me in the past, but doesn't work all the time.Has anyone found a better way of identifying the problem in the aspx file when the "Could not parse file" error is displayed?
I have got a SSIS Package running every 2 hours. It collects data from different DBs and updates the DB of my ASP.Net Application. Everything goes smooth, but the asp.net application is still using the old data, it has the data somehow cached. If I just open save the web.config, it empties the cache and uses the updated new data. How can I make sure, that the app empties the cache after SSIS Package finished successfully?
i have an html (save in a string variable if needed) and i want to use the content of one of the html's tables (the html page has 4 tables an i want only one of them) . i read a lot of similar post but i didn't find anything helpful. on how to parse the html and get the content of one of the tables so i can use this data later?
The data being passed to the C# function looks like:
lbItems=1&lbItems=3&lbItems=5
Is there any built-in C# function that can deserialize that easily, to convert the values into an array of some sort? Or maybe there's a better way to pass the data from jQuery?
I'm creating a web application using asp.net & WCF as 3 tier architecture, which is mostly looks like a social website. Users can register with the system and they can upload their profile images, documents, video clips etc. So, what i want to know is what is the best way to store those files? In the wcf side or web application side ?
Also I want to know that, if i choose web application side to store those files as set of folders, how it makes those folders shared and allow access to another different project (such as a desktop client need to upload files into that shared folder) ?
I am working on a railway web application and I have following layers:
[Code]....
I pass Domain Entity Objects from Repository to Service layer and thinking of passing View Models from Service to Presentation layer. Website would require a login and after successful login I have to present a search screen with basic search (as default option) and option for advance search. Once user fills the search criteria I have to gather data from DB & Web Services and present the results to user. User would select a particular Rail option and would move on to other additional options page BUT they should be allowed to change their previously selected Rail option by going back to Rail search results. I have to always hold and present user's initial search criteria (basic and advance search options selected by user on the search wizard) on every screen and need these criteria in Service and Repository layers.
What is the best way to hold these search criteria and pass them from page to page within presentation layer and across layers? Should I create a View Model class for Search Options? Or a Domain Entity Object (I don't think so)? and best way to pass it across layers and from page to page with in presentation layer.
My question relates to the performance implications of reading application configuration data from an XML file.I am building an application that lists information from a database and needs to know how to display the lists, depending on the types of data returned.This is difficult to explain, but basically I would like to have an XML config file that lists the types and describes how to display them. This will allow me to change the display methods without re-compiling the application.
My question is really around performance. Given that my application will need to use this data many times during each page load...Should I be reading directly from the XML file and parse it each time I need it? Or should I cache the XML object and parse it each time I need it?Or should I parse the XML once, generate some sort of object and cache that object?My guess is option 3, but I'm basically fishing for best practice around this.
I am working on a Railway Portal and would require maintaining a shopping cart of components user has selected, there could be multiple components of different type in the cart. I don't see a value in storing the cart in database, would like to store the final order in DB. Where can I store/hold (temporary) the cart data per user session in MVC? All MVC samples I saw online save the cart data in DB - not sure why.
MVC presentation layer will be communicating with external web services for pricing and availability of these components, so I can't store only the product IDs to do a lookup for actual product descriptions/prices during the shopping process... I have to store everything in the cart (Product IDs, Descriptions, Prices etc) some place in memory. My application will be running in WEB FARM environment and cannot use in-process session storage.
Options come to my mind are:
SESSION STATE in SQL SERVER Using some kind of Distributed Caching Mechanism to store Session data such as "Windows Server AppFabric"
Documentation for using a checkbox with a gridview has the following statement:Because a check box can display only a selected or an unselected state, a CheckBoxField object can be bound only to a field with a Boolean data type or a string that can be parsed byParse.No example has yet been found to explain how using Parse to control the value of theis done. Interestingly enough I can find a fine example for the unlikely scenario of embedding a bulleted list in a grid cell.
I have until now always stored my lists definitions for labels and values for dropdownboxes in my own defined Xml files. These lists labels I then match with a language file (.resx) ..... so far so good but now I am starting a new project. Should I continue with my old habbits or is there a better way of storing label constants for my dropdown boxes throughout my application?
I would be happy skipping my read and write rutines for my onw structure if there is a better dedicated one for the purpose.
General Flow is : Receipt, Dispatch, Issue.Receipt & Dispatch are normal.Item Received, Qty...etc entered through UI database updated.Item Dispatched, Qty...etc entered through UI database updated.Further Issue is subdivided into 3 types :1. Qty entered through UI DB Updated.2.Rates are defined for items & after entering the Qty through UI Amount is calculated.3.Scales are defined for Items & based upon those scales & the strengths of Consumers formula for these items is calculated.
I have VS 2008 and 3.5 framework.I want to set up my application that I can store my content to database.I have lots of controls that from labels to images, datagrids, telerik controls, etc to keep in mind.I use SQL server 2005.
What is the recommended or usual way an ASP.net web application(in C# language) can store/access values that are needed accross the various pages in a website. For example a basic company website might need the company's name and other related information available to multiple pages. Where do I declare these variables/values and how do I access them. Coming from c++ application programming I would usually store such data in a Singleton class object.
I need to keep access settings to different web pages inside of my asp.net application. These setting are logins and passwords for those pages. Is it safe enough to keep them in web.config in section?
I have some global settings in my application that is going to be handled by the administrator and I store them in the database.
Settings like: board on/off, max items/page on different UserControls, language, hide/show modules.
What technique should I follow to read the values in the database and display the page or the application according to it .. Of course I could do it the easy way and fetch the required settings for each page in the Page_Load event handler but I think that will be a lot of database connection!
