I'm using Content Management System, DotNetNuke for my dynamic website. DNN itself they have one database, I named it dnnDB. Inside the dnnDB they have the users table which have the list of users. I need to be able to pull this set of information or synchronize to my own database, myDatabase for development purposes. I do not want to incorporate my database into dnnDB, afraid that I may corrupt the system.
View 4 RepliesI have a FormView through which I set up the default new, update and delete commands for communicating with an SQL Server database. When the CREATE command is executed the data is added to the database and some images are uploaded to a server and linked to the database.
When I press the Visual Studio's default FormView DELETE command I obviously only delete the selected row in the database and not the images on the server. I marked the uploaded images with images ID + "name" , so I could delete them if I could only retrieve the ID of the row being deleted by the DELETE command. How do I do retrieve the ID of the deleted row in C#?

View 5 RepliesI'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?

I have a database created and I've successfully connected to it. My question is, would it be possible to do something like search the first column of a table for a value, get the index of that row and use the index to get the value of each column? Sort of like you would with an array.

I have a C#/Asp.net web application which caches SQL DB schema information. Is there a way that I can determine what child relationships a given table has? I have looked into using the DataTable.ChildRelations property, but it is never populated with items unless i manually create a relationship using the .add property. I also have access to DataColumn information for each column in the database.
