Perform Action On Each Record From SQLDataSource?
Feb 24, 2011
I'm using ASP.NET/VB.NET to create this with SQL 2005. I have a project where I'd like to take a set of records from a table, then send each one through an API, get a result and writeback the result to a table, then move to the next.
Initially, my thought was create a SQLDataSource that grabs all the records, then perform the action on a button to do the action of sending through each record.
Is there a way I can call the recordset from SQLDataSource and perform a loop? I'm thinking something like in Classic ASP/VBScript where you would open a RecordSet, do an action, then Loop until the RS was EoF.

I'm using VS2010, SQL2008 and using asp.net vb - im stuggling with some db related items.I have a couple tables, Project and Projectstatus - looking something like this.project
- ProjectID (autoincrement)
- ProjectName varchar50
- Projectoverview varchar200
Projectstatus
- statusID (autoincrement)
- projectID varchar50
- projectstatus varchar200
What id like to happen is that when i create a new project (into the project table),that a row is created in the projectstatus table, inserting the projectID from the project status for reference.I don't think this can be done from within VS, correct? therefore, do i need to create a SP to perform this action from DB side?

I have a WinForms DataGridView control on a form. There are two fields in this DataGridControl:
Email Address
Resolved Email Address (calculated based on the input in Email Address)
After the user inputs or changes a value in Email Address, I want the value in Resolved Email Address to update based on a separate method. What event should I tie in to so that that the Resolved Email Address cell is updated after the Email Address cell is updated?I'm not sure where to put the event because the user could do a number of things after adding/changing a value: tab to the next cell, click cancel on the form, click ok on the form, etc.

Basically, It is a program that allows you to automatically click things.
Here is the
Public Class Form1
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer
[Code].....
What I wanted to do was make an option to have variations in tick time. I want to put in a check box, and if it is checked then there will be 10 "variations" in click time, ranging from 1 second too soon, to 1 second late.

I'm new to VB and Windows programming but I do have a fair amount of experience programming at the command line level. A friend is having problems with his laptop. He does a lot of speaking engagements with Powerpoint. His laptop uses the F7 key to toggle the output to his external monitor port to the video projector. The F7 key has stopped doing this. Is there a way to create a Windows program that will do this without using a DOS window? He is not familiar with command line processing and needs something that he can double-click.

Say you wanted to set a status message
' Set status
ssMainMessages.Text = msgValidating
Then perform an action that requires a http request that takes around 5 seconds then you want to display the result of that
' Set status
ssMainMessages.Text = msgValidated
It will only always display the second message? Its like it jumps the first part of the code and goes straight to httprequest.even if you put the update,system,threading.thread.sleep ....

I had tested this code: [URL] It works, but a Word application is opened and each new paragraph added using VB code is seen one by one(with a small delay). If I want to open and write something using VB, what is the fastest way ? I do not want to view the changes made on word document live. I want to save the document. So will oWord.Visible = False makes it fast?

Basically i am making a software that will be interacting with a database (sql).Now what i wanted is a loop which after every 30 minutes, connects to the database finds some info and executes a bunch of statements.For the sake of testing i have made the timer tick at 1 second, and display a record in a database in a label continuously just to see if it works (i will later make the tick 30 min)Now this is what i have tried till now , it prints the record in database perfectly after 5 seconds, but after that just fails.[code]I want to infinitely make a loop in which after every 30 minutes has passed it would connect to the database get a record and then use the value of that record to perform some operations. And this has to be done in the background.

a datacontext defined in a module(domain services ado.net ria)a page having add/delete methods whenever any method is executed, it is found that all the previous actions (NEW RECORD ADDITION and DELETION OF RECORDS) are carried out before the new action is carried out normally
this behaviour is not prominent but "when using break points and inspecting the values of the variables and table object to be added to context, it is clear that all the previous actions take place again. even when the datacotext. savechanges is called, even after that still all actions carried out on the datacontext repeat themseleves, when any new action is to be carried out

I want to call a Stored Procedure using SqlDataSource. I've been reading the library documentation of the classes but i'm getting slightly confused. To call a stored procedure, I understand that I have to change the selectcommandtype and then set the selectcommand property to the name of the procedure.
'Change command type to stored procedure
SqlDataSource1.SelectCommandType = SqlDataSourceCommandType.StoredProcedure

I have an SqlDataSource object, linked to a GridView, which receives data from a database when executed.I'd like to add the values of the "Cost" column, to get the "TotalCost", and place it in a TextBox or Label on top of the GridView.Is it possible to just use (recycle) the data in the SqlDataSource object, instead of using another SqlDataSource object to just get the TotalCost"?
