ADO.NET :: Binary Tree - Want To Check All The Records?
Dec 20, 2010I m creating a project in which only two members can register by using one perticular ID as a Sponser ID. I am using VS 2008 with C# language and LINQ as Query. At the point of insertion for register entries, i invoke a method BINARYCHECK which contains LINQ query. I passed _txtSponserId as a parameter to the BINARYCHECK method. Now in the function definition section i have written LINQ query which checks in database that if particular sponser ID is bieng used maximum of two times by any other user. But i only can check one record in the database. I want to check for all the records. Below is my code:
var a =UserBl.BinaryCheck(_txtSponserId);//function call
public static List<tblUser> BinaryCheck(string s)
{[code]....
This code doesnt check for how many times SponserID is Used. This is why i get i=1 and return data even if SponserId is used only One time. On the contraty i want to implement that if SponserId is used only once in database then function should return null other wise it shold return 1. How to do this?
DataSource Controls :: How To Traverse A Binary Tree
Feb 23, 2010 I have a table in my database that holds the parent child relationships for a distributor binary tree. I need to be able to return this query into my application and have a recursive method to go through any given tree and traverse through all subtrees of the parent tree in order to calculate commissions. Does anyone have any working examples of binary tree traversal?
Also, I'm not exactly sure how I will pass this tree structure to my application. Would I return it as XML?

Web Forms :: Display Binary Data In Webpage?
Jul 28, 2010I need to display binary data (that is stored in the database) in the aspx page. The file types are word and pdf. Since there might be multiple files, what I did was created IFrames dynamically and tried to embed the binary data. The problem is rather than embeding the word doc or pdf doc in the page, it displays the open/save dialog box.
is there any way to solve this (embed the word/pdf doc in the page itself)?

C# - How To Write Binary Data "as Is" To Registry (ie: I Have Visible Binary Data As String From Regedit Only)
Feb 23, 2011I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out... I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically.
here is the culprit!
[Code]...
If I had the following in a string or a bit array, what must I populate the bitarray with so that the registry outputs this [above] when written? or, how can I figure out how to do it? I was hoping there'd be a function that reads my string of binary data and transforms it into the real binary format to submit to the RegSetValueEx function in VB6 or other function in VB.Net or C# (this really is a language agnostic question, and the problem exists in all languages; ie: same process).
