Complex number with evaluate function

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :WPF
 

Hi

I want to read a complexnumber and evaluate the result. Like this:

(5+i)^2

Here goes:

    Dim NumType As String = "(?<Both>([-]?\d+\.?\d*|[-]?\d*\.?\d+)(?=([^i]|$))\s*\+*\-*\s*(\d+\.?\d*|\d*\.?\d+)*(?:i))|(?<Real>([-]?\d+\.?\d*|[-]?\d*\.?\d+)(?=([^i]|$)))|(?<Imag>(\-*(\d+\.?\d*|\d*\.?\d+)*(?:i)))"

    Dim rePower As New Regex(NumType & "\s*(\^)\s*" & NumType)

  If rePower.IsMatch(input) Then
      TextBox2.Text &= rePower.Replace(input, AddressOf DoPower)
    End If

The problem is related to the rePower logic in the DoPower function:

 Function DoPower(ByVal m As Match) As

How to debug a complex function?

  
Hi everybody, I got a few complex functions written by my colleague to review. These functions calculate cost of goods using one of the methods (passed as a parameter) (FIFO, RWAC, LAST cost). I've been looking at these functions or running some queries based on these functions, but I'm yet not sure I understand them fully and their logic. What is the best approach for me to test / understand these functions? Thanks in advance.Premature optimization is the root of all evil in programming.

dynamically adding sql server columns based on number of files in fileuploader

  

I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.

 

I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Embeb a variable number of videos

  

I need to provide some alternate content for my non-Flash users.

I have a directory of video files that is scanned using the DirectoryInfo() function, and I want to use the results to embed all files ending in ".mov" in QuickTime players on a web form.

How would you approach this? Right now I am using the count on the array of videos to determine how many times to repeat the embed code.  But this seems inelegant.

Is there a way to have a single QuickTime player.ascx control that gets duplicated according to the number of videos available for display?


MVC too complex?

  

I believe lot of people will disagree with me on this one. But the MVC model sucks. The reason:

1.       Over complicated;

2.       Cannot handle complex UI;

3.       Hard to debugging as code scattered all over the place.

Article commenting by line number

  

I'm wondering what's the best way to approach an online article system that allows users to comment by clicking on the line they are commenting about? Essentially the same way Adobe Acrobat works with comments where you can click anywhere and the text is saved for that location.

I'm assuming a mix of jQuery would be the crux of the interface. The system would need to save comments so that when another user logs in, they will also see the other comments but they can´t edit them - only add their own.

Any suggestions would be great.

Public Shared function doubt????

  
Hi
I am using VB.net/ASP.NET and SQL Server 2000 for a web application.

For populating the dropdowns, I wrote a Public Shared function LoadDDL(), in which I pass the dataset and dropdown name to set.

I have my doubts that this function will produce unexpected results for concurrent users. And will mix the results among sessions because it is a Shared function.

I am confused here. Is it the right way to go?

Please advice. Thanks in advance.

How do I persist custom complex types in design-time

  


Let's say that I've got one custom webcontrol called MyControl.



[ParseChildren(true)]
public partial class MyControl: WebControl {
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
[PersistenceMode(PersistenceMode.InnerProperty)]
public IComplex Complex { get; set; }
}


The control is a very simple control but it holds an instance of a complex type that is accessable through a property. The property has the propertytype IComplex


public interface IComplex {
string Name { get; set; }
List<IComplex> Children {get;}
}


Let's say that I am able to pick one of several different types of object that derives from IComplex in design-time and assign it to the controls property "Complex" property.

Naturally I would like to persist this information to the HTML-View in a user-friendly way.

Because we don't know what type the user has picked there is no way to instansiate the type if we don't persist the name of that type. The Type could also contain more properties than the Interface the controls property is refering.


<cc1:MyControl id="MyControl1" runat="server">
<Complex> <!-
