If want to do a DataView.Find on a DataTable that is already 'ORDERED' by the Column I am seaching, so a DataView.SORT should not be necessary, but it throws an Exception if I don't give a .sort command before the .find command. Is there any way to avoid this apparant duplication ? and speed up the search time. Its a very large table - 1 million rows. I am using VB 2010

I have a form where I open an Access database with 3 tables. I have defined datasets and dataviews for these three tables in the main form. I want to open a new form and access and update the tables using the dataviews I've already defined. When I try to access a record from the dataview using the new form, it's not defined. Can I pass the data between forms or do I need to redefine it in the new form? This is the first time I've tried to use multiple forms.

View 2 RepliesIs there a way to keep from extensions from appearing as global subs, even when you are not dealing with the relevant type? I guess from how they are created, they always show up as global functions whenever I use intellisense, which, depending upon how many extensions there are, can be a pain. I want them to appear only as methods to the relevant type variable.
View 3 RepliesI have an array of comboboxes on a form. They are declared at the beginning. I wish to make these global variables so I can access them in another form. This does not appear to work.
Code something like this:
Public Class SecondScreen
Public OutputSelectControl() As Combobox = {O1, O2, O3, O4}
Where O1 O2 etc are the names of my comboboxes on this form. I wish to be able to address them from another form like so
localformvariablehere = OutputSelectControl(integervariablehere).Index

View 4 RepliesI have a main form with 2 splitcontainers. On the left is a richtextbox showing the clients details and how many active tickets they have open and cmd buttons which opens different uc's within the container on the right.What I am attempting to do is when a client raises a new ticket, that the global variable holding the ticket count number updates via a procedure and updates the richtextbox on the main form.The line of code that runs within the UC is:
formMain.SplitContainer3.Panel2.textUserDetails.Text = FullNameSQLString & vbCrLf & UserDepartmentSQLString & vbCrLf & vbCrLf & "You have submitted " & Global_FCRCount & " ticket today."
The part I have highlighted errors with the following reason: 'textUserDetails'is not a member of 'System.Windows.Forms.SplitterPanel'.I have checked and double checked the form names etc and textUserDetails definately exists within formMain.SplitContainer3.Panel2.
there is any event or way to detect activity in an form or project?in the form and all the child controls.
mainly mouse clicks (not mousemove) and key press.
for example, if the form have not activity in the lasts 10 minutes, do something.

This is a part of a calculator code. When you press the button "BtnAdd" the text in TxtRes is held by the global variable "num1" and the operation number (whether add or subtract) by "oper". My problem is : OUTPUT 1: prints num1 = 25 (for example)While OUTPUT 2: prints num1=0
Why is this happening ? Isn't the value of num1 supposed to be equal everywhere in the form at a given moment ?

Ive done a login in vb.net (Visual Studio) which works like a charm. However, i need to store the username of the person that has logged in, in some form of cookie. How can i store the persons username in some form of global "cookie"? It will be cleared when they log out or the program closes PS. I dont literally mean a web cookie - just not sure what else to call it. Just a global variable which will store the current user.

Looping through rows in a DataView
I have created a dataview from a datatable.
My question is how can I loop inside the dataview?
I know that in a datatable I can perform a loop like this:
For Each oRow as DataRow in iDataset.Tables("tableName")
Msgbox oRow(0).ToString
Next
How do i do that for a DataView?

I have a sqlDataSource that runs a stored procedure that returns a table of the days of the month that was passed in as a parameter, arranged as they would in a calendar. It also returns a second table which contains the event details associated with certain days of the month.Basically, how would I go about accessing the values contained in the 2nd table that is returned by my query?I have tried putting the result of the .select in a dataset, unfortunately I get a cast error. If I try to put it in a dataview, I only get the first table.[code]
View 3 RepliesI am trying to create a basic webpage that will check a column of a database table to see if a "UPC Code" is taken already, to prevent duplicate use. I'm fairly new at .NET programming, but have built asp pages before. I'm just stumped :/
I have a textbox that a user can type in a number. The page successfully checks to see if the textbox is blank and reports the error, and if there is a value, it's supposed to bind that textbox number to a gridview to see which Item# it's associated with. But for some reason, my code is not binding the value of the textbox to the gridview.
Code:
<%@ Page Title="Home Page" Language="vb" MasterPageFile="~/Site.Master" AutoEventWireup="false"
CodeBehind="Default.aspx.vb" Inherits="UPC_Checker._Default" %>

I have a form which is primarily pulled from Table1. Table1.fieldA is an integer representing a project phase. In the current Access display the form displays not the integer, but a String stored in Table2 that holds integer/String pairs representing all the phases.I'm trying to figure out the best way to reproduce this in my .NET formview. I could write code that would parse the int and display text, then reverse the process at save or insert, however then the code has to be updated if a new phase is added to the database. draw the String values from Table2 while preserving the binding to Table1 but I haven't figured out how.
