Results From A Query Into Multiple Textboxes?
Aug 17, 2011
I have an assets table, which in it has the amount, growth percentage, income percentage. There are multiple assets per client.
I need to get the amount, growth and income into three separate boxes or variables and I'm not quite sure how to do this. The only other problem is that there would be two or three rows returned also, which need to have those three variables or textboxes again. So for x amount of rows, I need 3 variables which the amount, growth and income will go into.
The reason I need everything into variables is that I can't find an effective way of showing each assets growth over x amount of years and the income it will produce into a data grid view. I'm able to do it if I specify what the growth and income are on the form, but not through the query.

This is my first attempt at writing a program that accesses a database from scratch, rather than simply modifying my company's existing programs. It's also my first time using VB.Net 2010, as our other programs are written in VB6 and VB.NET 2003. We're using SQL Server 2000 but should be upgrading to 2008 soon, if that's relevant.I can successfully connect to the database and pull data via query and assign, for instance, the results to a combobox, such as here:

How do I execute a query so as to assign each field of the returned row to individual variables?

I have a VB .Net linq query that I want to return values from two tables. I currently have this:
Dim query = (From c In db.Client _
Join u In db.Users _
On u.UserID Equals c.UserID _
Where (c.ClientID = 1)
Select c, u).ToList
query (System.Collections.Generic.List(Of )) returns several rows as expected each item containing a c and a u.
How do I iterate through the queries collection?

Ok, the basic situation: Due to a few mixed up starts, a project ends up with not one, but three separate databases, each containing a portion of the overall project data. All three databases are the same, it's just that, say 10% of the project was run into the first, then a new DB was made due to a code update and 15% of the project was run into the new one, then another code change required another new database for the rest of the project. Again, the pertinent tables are all exactly the same across all three databases.
Now, assume I wanted to take all three of those databases - bearing in mind that they can't just be compiled into a single databases due to Primary Key issues and so on - and run a single query that would look through all three of them, select a given set of data from each, then compile those three sets into one single result and return it to the reporting page I'm working on.

I am creating an application for a friend and have no issue inserting or updating the table, but I am having trouble relaying the information from the query back to the corresponding textbox when searching for an entry.
This is the closest thing I've got to a working model, but I'm still getting and "array out of index error".

I have a question regarding the dataset usage in Reporting Services. I have a stored procedure which returns multiple select statements (result tables), and I created a Dataset in Reporting Services 2005 with this stored procedure. The problem is that I can not reference the second or third result table, and I can only use the first select statement fields. Is this the limitation on Reporting Services Dataset or is there a way to use multiple table results in one dataset?

I have the following code:
For Each control2 As Control In GroupBox3.Controls
If TypeOf control2 Is TextBox Then
Dim txt2 As TextBox = TryCast(control2, TextBox)
If counter > totalBoxes Then
[Code]...
What I am doing is looping through each textbox in groupbox3. Then checking if the counter(total number of grades that are inputted in the form) are greater than the totalBoxes(which is set to 0) and finally I am putting the actual grade(A,B,C,D) into the textbox. The problem is that it is starting the loop at textbox 8(I have 10 textboxes) for some reason and going from there. Does anyone know what the problem is with my code?

If this is in the wrong section, I have a program that queries a database and puts the info in a specific format in a txt file. Now my problem comes w/ how to format the date.
Should I format the date in the SQL query OR is there a way to take the result from the query and format sometime before it is writen to the txt file? I'm not exactly sure how to do either. Would I need a subquery to get the desired date format?

I am familiar with the VB6 ADO way of dealing with SQL queries and looping through the record set results.
However, what is the correct way to query a server, cycle through the results, and dispose of my query in VB.Net? All the ways I have been using seem to be unstable and crash randomly.
I have been using the following code:
Public Function GetSQLTable(ByVal strSQL As String) As DataTable
Dim table As New DataTable
Dim adapt As SqlDataAdapter

I'm trying to execute a SQL query and pull the results into a text file. However, I'm getting an error in the bolded part. I think probably the biggest help would be an explaination of what the code in bold is actually doing. I pulled this from a book but don't think I completely understand. To me it seems like its saying that for each row in table 'extract'. Extract it, and write it?? But it doesn't seem to work that way. When it gets to that part, the error I get says that the row doesn't exist in the table
Private Sub btnExecute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExecute.Click

I have a query using LINQ-to-SQL. It queries an underlying database table Rooms. It uses Where conditions to narrow down the results, namely:
Gender.Current Occupancy < Max Occupancy Available Flag is Checked I know this should return results but it keeps returning an empty set.Code is below
[code]...
UPDATE: I've verified that the issue is with the statement where sh.is_available = 1, which doesn't make sense since this is a bit field.

Why would a VB/ASPX page not return results for a query which runs fine with other Oracle clients? (Same username) The following code should first output the query and then execute it outputting a single exclamation point per record. However, it outputs the query (as it should), but does not return any rows (nor error). If I copy the query to SQL Plus (or other editor) as the same user, the query returns results.
Why might my code not output any results?
Dim MyQuery As String = "...some query..."
Dim Factory As DbProviderFactory = DbProviderFactories.GetFactory("System.Data.OracleClient")
Dim myConn As DbConnection = Factory.CreateConnection
Dim myCommand As DbCommand = Factory.CreateCommand
Dim MyReader As DbDataReader

I have a basic question about using a database with Visual Basic.I'm using a OleDb connection. I have dragged and dropped editboxes from the DataDource view. This automatically places the table navigation- bar on the form. When I run it this works fine.However I want to be able to search within the table, with an SQL statement.How can I connect the results from the SQL query to the navigation bar,such that the editboxes automatically take the values of the record without having to assign every textbox manually?
