Asp.net - Iterate Through Custom Object's Property Names And Values
Sep 1, 2009I'm trying to create an export Excel/CSV function that will iterate through a custom object and first output the property names and then output the values. I want to use reflection only where necessary so I'm attempting to save the property names when I output the headers and then reuse them to print the values. Is this possible? I'm a little weary of using reflection in a loop but is there a better way?

Store Retrieved DB Values In Variables?
May 31, 2010I have a database in my app which loads and displays some information on a form by binding the Comboboxes and Textboxes. However, I need to get some of the other values from the database for calculations before they are displayed on the form and I can't seem to find out how to do this.I could bind a couple of Textboxes to the database and then use those values to calculate, but it doesn't seem like a very efficient way of doing things.The dataset is created using the wizard and the controls are linked in the UI.
Please bear with me, I'm still a noob.

Copy TextBox Values And Names?
May 5, 2011Basically I have a form with Five textboxes and what I want to do is to click a 'Submit' button and copy not only the text from all 5 textboxes but the name of the textbox or a label.
Sample:
Names / TextBoxes
Box1: Text1
Box2: Text2
Box3: Text3
Box4: Text4
Box5: Text5
And when you click submit you would get the text in that format when you paste it in a separate textbox.Is it possible and how would I go about doing that? I know I can copy multiple textboxes but I want to retain the label or title along with the filled in text.

Construct Object Names At Runtime?
Jul 15, 2011Is it possible to construct the name of an object (in this case, a Panel control) at runtime?
What I want to do is change the Backcolor of one Panel that is a member of about fifty panels. I can get the string of the name from the Sender in a RadioButton CheckedChanged event. So what I want to do is something like:
PanelName = sender.parent.name & ".BackColor"
PanelName = Color.Red
(I realize that the syntax above is invalid. I'm just using it to try to get the idea across.)
I can do what I need with big, fifty-element Select Case blocks, but the code is so repetitive that I was hoping there was a more elegant way.

Asp.net - Getting Table Field Names As A String?
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 RepliesGather Names From Values In SQL, Add Them To Multiline Textbox?
Apr 12, 2010I would like to add the names of people in a SQL Database to a Multiline textbox if two values in their row do not equal 6. The first name and last name, as well as graduating year need to be added to the textbox, and then a new line needs to be created. The two values are contained in two separate columns in the DB. I'd like to try and stay away from using SQL Queries to accomplish this, so is there any way I can call these values using VB? Keep in mind the number of people that have values under 6 may vary from time to time. The purpose of this will be so that someone can print out a list of members who don't have the required amount of points at any given time.
