Using A Repeater With A Dynamically Generated Table, Ie, So Unknown Field Names?
Feb 25, 2012I'm trying to produce a repeater showing amounts of money taken by various payment types into a table.Payment types available come from a global settings file as an array, I am creating a dataTable by looping this list and extracting sales reports (there might be a more efficient way than this loop, but this is not my concern at the minute).My question: How do I bind this to a repeater and display it when I dont necessarily know the table column namesI've tried various methods to give the table a header row and give the columns numerical names from a for > next loop, but am either getting no results, orystem.Data.DataRowView' does not contain a property with the name '7'. < or whatever numberThis is where I currently am:
EDIT: JUST REALISED MY CODE WAS AWFUL, SO UPDATED:
Dim paymentTable As New DataTable("paymentTable")
For j = 0 To UBound(paymentTypes)

Oct 28, 2011I'm trying to get the list of field names for a given table, to turn them into a string which I can to post back as a variable to another function.I've Googled loads of stuff regarding GetSchemaTable but all I seem to be able to output are field parameters, but not the actual value of these parameters (ie ColumnName, which is the one I actually want!)
Found this page; What is the SQL command to return the field names of a table?But all the queries on there give me an error "You do not have access to Table 'Columns'"I feel sure this is pretty simple, can someone give me a little function that will simply give me fieldNames = "fieldName1, fieldName2, etc"I am using a MySQL server and ODBC connections ASP.NET using VB.

View 2 RepliesGet Columns Names From Table And Pass Parameters Dynamically?
Sep 14, 2011I am trying to figure out how to do this or if it is even possible. I believe it should be, I have about 20 different tables with different amounts of columns in each table. I.E. One table might only have 4 columns while another might have 30 columns. What I am trying to do is create 1 sub/funtion that will handle the select and import for all 20 different tables, unfortunately for me I can't seem to figure out how to write this.
I know the select statement for getting the column names is :
SELECT column_name FROM INFORMATION_SCHEMA.Columns where TABLE_NAME = 'table'

VS 2008 Field Names Of A SqlDataReader Object?
Mar 2, 2010I want to write a routine that loads a table (or query) and outputs it to a text file, with the field names in the first row.If I load the data via an adaptor class into a datatable, I can access the field names by something like DataTab.Columns(i).ColumnName.
As I only want to read the data from the table, using SqlDataReader would be more efficient. But how can I then find what the header or column names are? The following code fails with a message that the SqlDataReader class does not have a member called 'Columns ':
Dim sqlCmd As SqlClient.SqlCommand = New SqlCommand(SQL, Connection)
Connection.Open()
Dim Reader As SqlClient.SqlDataReader = sqlCmd.ExecuteReader()
Dim FName0 As String = Reader.Columns(0).ColumnName() '<==FAILS
Is there a way to find the column names of an SqlDataReader object?
Procedure To Group By Family (Last) Name Then Concatenate All First Names Together In A Second Field?
Oct 20, 2011create a mailing list of my students with the usual lastname, firstname, address, city, state, etc. This all works fine - except that I'm getting multiple records for the same family when they have more than one children in our database. So, ideally, I would like to be able to group by the family name (which is grouped in a seperate Family table then linked to the student table by familyid), then in the second field list each child of that family separated by a comma.
View 1 RepliesVS 2008 DataAdapter.Update - Field Names Have Numbers?
Nov 4, 2009I posted in the Database development forum, but no bites. I have field names in my Access table which have a number as the first character (i.e. "2x2"). Evidently, the DataAdapter doesn't like this. I'm able to view the data in a DataGridView, but I get an exception when I use DataAdapter.Update.
Can I modify my sql statement to make the command builder work or do I have rename the fields?
For example:
"SELECT [2x2] as twoBytwo..."
Changing the names of the fields would be a huge pain-in-the-arse!

Asp.net - Getting Form Field Names On Submit When Form Is User Control
Jan 30, 2009I've created the beginnings of my new web application, but I am often coming up against the issue that ASP.NET renames elements IDs or in the case of form fields, their names.I have a form which is basically a sales system. It is essentially made up of two User Controls, one is a form for Customer Details (name, address etc) and the second is a form for the customer's purchases, it consists of a number lines dynamically created by Javascript created as you list the items the customer is purchasing. Both these sections are User Controls because they are to be used for other areas of the system where this data will need to be recalled/re-entered.When the USer Control is loaded, the field which contains the Customers' Name is renamed "m$mainContent$customerForm$name" I understand where this comes from, "m" is the ID of my Master Page, "mainContent" is the main Content Placeholder and "customerForm" is the name of the User Control.
In fact, in my case, this will always remain the same on all forms, so it is relative easy to overcome... but... suppose it wasn'tI can see there are ways I could deal with this with Javascript, but the form doesn't need an AJAX submit, a normal Post will do fine for this, so when I open up the recieving page I want to call Request.Form("name")% to save the customer's name into the database, but of course I really need Request.Form("m$mainContent$customerForm $name")%How would I dynamically extract those prefixes from the posting form to ensure that if I rename anything or use it in a different scenario, the problem will not break it?I am using .NET 2.0, so can't use Static Client.

Create Folders Based On File Names
Jan 2, 2009I have a directory with about 200 files in it. Is there a way to create a folder for each file with the folder name being the same as the file name minus the extension and then put the file in the folder.For example: Folder "test" would be created from file "test.doc". Then the file "test.doc" would be moved into folder "test".I have some experience with visual basic, and my thought process for this was: make a loop that brought in each file name > store as a variable > create folder with the name in the variable > remove the last four characters from the folder name > move file into the folder > clear variable > repeat.

I do not want a separate folder created for ABC_rock, ABC_soil, and ABC_water.
