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?

I 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?

I have several cases in my database and for each case there is binary data. I am reading binary data for each case in a byte attray and saving it as a pdf file.I can succesfully open this pdf file.
protected string SavePdfFromDB(string caseNum)
{
string PDFFileName = string.Empty;
SqlDataReader dr = csiDelegate.DataReaderProcedure("GetReportFilenameForFileSystemNewestFile", [code]....
Can I read this binary data for multiple cases in the same byte aray and and save it as a pdf? Will this create a valid readable pdf?

My apps required me to store upload files into SQL binary fields. And then allow users to retrieve the files and either chose an apps to view them or save on disk. These files can be in diff formats, not just one type.
I have been reading about using the Response.ContentType method and Response.AddHeader method. The issue is the users can upload anykind of documents, ie: MS words, Xcel, JPEG,TIFF.... So at the time of downloading, I have no way of knowing that type it is to put in the Response.ContentType.
Can't I just stream it to the browser, let the download dialog box handle the type selection? as in when you download a file, the dialog box would ask if you want to select an app to open the file or save it on disk. How would I do so ?

I installed MS SQL Express 2008 with Advanced Services including Management Studio 2008. When I connect to the SQL server of my provider (shared hosting - one SQL server for many customers), it takes very long (up to serveral minutes) until all DBs are displayed in the object explorer (from which I then have to choose my DB). Somebody told me, the long waiting time occurs because Management Studio first checks rights (whichever rights that may be) with every DB that runs on the server.
But in Management Studio 2005 the behaviour is different - the DB Tree in the object explorer expands immediately! No waiting time! Does anyone know a solution for this? I don't want to install two separate versions of Management Studio just because of that!

Is there a way to do this in either scalar function form or in an aggregate function form? The problem I'm dealing with is building a security system with multiple tiers of inheritable permissions. Like you'll inherit certain permissions form the department level and then certain permissions from the supervisor level. I'd like to find a way to produce these resultsFor user permissions I pull these binary values and get these results, (they are sorted by their tree node depth level in the hierarchy.

I am using Sql server version enterprise edition 9 on win NT.I have an issue with the stored procedure, when I execute the SP I get an error message "String or binary data would be truncated." In general I know that we get this error when the inserted value is greater than the column length, but in this scenario the SP is failing only the for the section 1 insertion. The same SP contains one more section where we are inserting records in to same table from same source table based on some different condition and it works.I wrote a script in which I copied the section from the SP which has the problem and storing the output of it in an temp table and inserting one by one record using cursors in to the destination table and then it works.I tried with the option SET ANSI_WARNINGS OFF and SET ANSI_NULLS ON, but it did not work. I am sure that it is not failing because of the length of the data inserted.Is there are other configuration that i can set??

Does it look like I will be stuck with manually compiling the tables of departmentpermissions and supervisorpermissions base on every possible outcome of inherited permissions or is there a way to do this on the fly in an efficient manner?

I,am trying to create a self association relation for an organization chart data tree in Entity Framework,after trying different ways for prevention of exceptions like 3007 and etc. I found that when I put my foreign key in my POCO near Parent and Items navigation properties its work.but I think this is not correct that we have both ParentID scalar property and Parent navigation property. review this and tell me is it correct or not.I'm using VS 2010 RC and ofcource .net framework 4.0 RC

cannot update tree node when update the forms. so i reload tree view.
now i need how to auto selected index change to tree node.
ex.
1 parent node
1.1 child node
1.2 child node
i have update "1.2 child node" rename to "1.3 child node"

I have a problem with deserializing in C#/ASP.NET, which gives the exact error:
The input stream is not a valid binary format. The starting contents (in bytes) are: 41-41-45-41-41-41-44-2F-2F-2F-2F-2F-41-51-41-41-41 ...
What I am trying to do
I have a structure with 3 classes. I have a class A which is a base class, and then class B and C which are derived from A.
I am trying to store random types of B and C in the database using LINQ to SQL, in a column with the type VARCHAR(MAX).
I cannot use BINARY as the length is around 15.000.
My code...

So the error happends when the first Deserialize method is run, with the above error.

I have a list which is defined as List<SoftwareTitles> softwareTitlesList = new List<SoftwareTitles>();
and the SoftwareTitles is a class which is defines as follows:
public class SoftwareTitles
{
string softwareTitle;
string invoiceNumber;[code]....
And now I'm adding the values from the sql server database to the list defines as follows:
public List<SoftwareTitles> SoftwareListRetrieve()
{
ConnectionToSql con1 = new ConnectionToSql();
string connectionString = con1.ConnectionStringMethod();[code]....
I want to find out the software title for every occurence of invoice number by looping through List<>. And I don't know how ? I have tried to loop through the List<> by the following code. I wanted to use something like contains i.e., softwareTitlesList[i].contains but seems like there is no such property or method
for(int i=0; i<softwareTitlesList.Count;i++)
{
softwareTitlesList[i].

I 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).

I'm doing an MLM website and I have a table that holds parent-child relationships as well as the position (L or R) in the binary tree and the Level. Top node is level 0, his two child records are level 1 and so on. I'm lost as to how to find the next available node that doesn't have 2 child records associated to it. This is for tree placement when I register a new distributor in the tree. I need to find out the first record that doesn't have 2 child records to assign the newly created distributor that sponsor id. I also have to assign the new distributor a position (Left or Right) in the tree. If there are no children in the tree then I assign them L if there is a child already then I assign them R. Is this better to do with SQL queries or bring in the data and parse through the tree to get the answers?
