Accessing An Object That Implements SelectMethod For ObjectDataSource?

Nov 8, 2010

Is it possible to access an object that is used by ObjectDataSource to retrieve records? For example,

<asp:ObjectDataSource ID="MyDS" runat="server"
SelectMethod="getUsers"
TypeName="DataSources.UserDS"
SelectCountMethod = "getUserNum"/>... </asp:ObjectDataSource>

UserDS class has getUsers that returns DataTable and getUserNum that returns int, this part works as it's supposed. But I wonder if can access the instance of UserDS somehow (not underlying DataTable)?

I'm trying to use Dot Liquid which is one of the coolest templating engines for c#.

Dot Liquid uses a way in order to make using templates safe. Here is the explanation page.

Here is the Explanation from it's wiki:

[code]...

So when I pass DataRow to liquid, liquid wont let me show it's content and tells me that:

'System.Data.DataRow' is invalid because it is neither a built-in type nor implements ILiquidizable

Is there any solutions to pass DataRow object that implements ILiquidizable too?

Any Free Reporting Control To Display Financial Statements?

Nov 27, 2010

I need to display many pages of financial statements on ASP.net and I have already had these numbers stored in database. I tried to use Gridview but it is very hard to display the sums etc and we have to write code for every subtotal which takes me forever. I decided not to use Gridview but just wondering what free reporting control to use for my scenario.

What I need to do on the page is to present income statements like this:-

Sales Revenue 2000
Cost of Sales 1000
----------
Gross Profit (calculated field) 1000 (=2000-1000)
Admin Cost 200
----------
Net Profit 800 (Calculated Field = 1000-200)
======

The above is over-simplified version and there are many many sub-totals in my page.

All I have is Microsoft Access datasbase and I don't have full version of VS 2008 so I don't have crystalreport.

Is there way I can have free crystal report or any kind of open source reporting control that work well with ASP.net ?

SQL Server :: Design A Stock Financial Report System ?

Aug 27, 2010

i want to design a stock financial report system and fortunately i hooked in the database design part. The report is made up of different sector and under the sectors thier are companies. All sectors have some unique entry fields which makes it different from the other. for example banking sector is different from insurance sector because there are entries that differ. My problem is how to create a non-redundant database that features all the sectors and companies. the idea i thought is to make a table for every sector and i found out that with these idea i wil have some relational issues for example in each sector i will have company id as primary so in establsiing relation i will hav constraint.

how to design a non-redundant databse with respect to these subject.

C# - Twitter Api Library / Get The Twitters From Parse Out The New Ones And Use A Library To Retweet Them On Own Account?

Mar 2, 2010

I am looking at the twitter api page http://apiwiki.twitter.com/ and I noticed that they have already built libraries that are wrappers against the twitter api. So I am thinking this is the best way to go but I am unsure which C# library I should use.

What I am trying to do is make some simple service or cmd line application that will help me automate retweeting.

So I am looking for a library that will allow me to get posts from other twitter accounts and then retweet them from another account.

I am not sure if the library can do this or not. Otherwise I was thinking of getting the RSS feed from the twiter account I want to get the twitters from parse out the new ones and use a library to retweet them on my own account.

I have not used twitter much so I am hopping someone can shed some light on this.

Converting Strings For Mathematical Calculations?

Jul 15, 2010

I'm new to .NET and converting and proper way to convert strings to other values. Specifically, here is a situation I'm facing:

I'm returning two values from a datasource as strings. One values is a representation of a span of time, and another is a count of how many attempts to access a system took place within the span of time.

Given these parameters (for example):

Span of time: 00:01:00
Attempts: 13

I'd like to calculate a third value that shows how many seconds each attempt to connect took place during that span of time. This involves converting the time span to seconds and then dividing by attempts. Where I am getting lost is with the conversion of types. I know the span of time needs to be converted to a date, reduced to seconds, then converted to a number to be divided by the attempts field, also converted to a number.

I've been playing around with code segments like this all morning to no avail:

VBNET Code:
Dim thisTime As String = "00:01:00"
Dim thisAttempts As String = "13"
Label1.Text = thisTime
Label2.Text = thisAttempts
Label3.Text = Math.Round(Integer.Parse(Convert.ToDateTime(Label1.Text)) / Integer.Parse(Label2.Text), 2)

DataSource Controls :: Static Value Vs Repeat Calculations?

May 13, 2010

I'm building a site where users can purchase 'credits' and buy items on the website with them. I'm wondering, what is the best way of storing the user's overall Credits value? Is it best to do a SUM() of all Credits they have purchased before from the 'Credits.Orders' table, or for performance purposes when they add credits to their account, should it increase a 'Credits' field value in a 'Users' table? For consistency purposes I would like to go with the first option, but the second option sounds better in terms of not running loads of pointless calculations every time I need to know their credit value.
