Asp.net - Search Queries In .net?
Aug 3, 2011
I am trying to perform a search query using drop down boxes with a button named search. I want it to bring up the data that is searched for. I dont know where to start from, i have looked around for some coding and different ways to do it but they seem complicated, this is the bit of ASP that is my weakness, need some assistance and guidance. below is the code for the page;
<%@ Page Language="VB" MasterPageFile="~/MasterPage.master" AutoEventWireup="false" CodeFile="ForSale.aspx.vb" Inherits="Users_ForSale" title="Properties For Sale" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>

i am creating a program in vb.net and was wondering if there is a way to perform multiple queries with one button without adding a second button. like i have two text boxes, one is for date and the other is for name. what i want to do is if i hit search and both the date and name boxes are filled, i want it to search for the name based on that date. but if only the name is filled i want to search for everything under that name.This is what i have. right now it only does one search:

I have a Access 2003 backend db and I'm using vb 2005 to connect to the db via conntection string. It works ok! I can see all the tables but only some of the queries. Why should some queries be absent? In 1 query I have a user define function which cuts up a string. I've created a new VB project with a new connection but the same result. I've compacted the database with not change.

Where can I find informations on which WMI queries are in fact available for .NET interface through ManagementObjectSearcher. The command below returns exception for "Win32_LogicalDisk", but works for "Win32_Environment". Every reference in msdn directs to msdn library, which contains all Win32 and COM development classes (that seems not to be available from vb .net code):

I've been going through a lot of forums and see a lot of mention of ADO.NET and how it's better to use. I guess because it's newer and being maintained with current times?I've done google searches for this, but every time I see different programming languages other than VB.NET implementing param queries with ADO.net, or it brings me to results that have oledb commands again.Is there a good ADO.NET for VB.NET tutorial with parametrized queries?

I want to send the a vb.net application which will run some updates on the database. I have built the sql script files which i would normally run thru query analyser but that is not available thru MSDE.I know i can use OSQL or ISQL to run these scripts but i really want to run them thru a VB.Net application.here is the code i'm using which is generating an error beacuse i'm trying to execute more than one statement?
Dim connectionString As String = ' CONNECTION STRING IS HERE

i have a form which once the user has entered their correct Account No they will access the jobs relating to their number. I now need to use and update query so that once I select yes in the Query handled box, after clicking the update button, this row will then be deleted from the table. Here is the code that I have so far:
Public Class Form1
Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click

I am a beginner when it comes to VB express. I went to the FAQ and found what looked like the answer to my question in "Database - How can I put the value of a variable/control into my SQL statement?" which said I should use thecode ...... where Field = ' " & variablename & " ' at the end of the SQL statement
I am using a field defined as a nchar with 10 charecters and my variable is defined as a string. my field has been given the value "abcdefghij" so it is full to avoid confusion with spaces and even though the variable is identical and I have used the len command to check there are no hidden spaces etc. When I run the query I get no records selected. What am I doing wrong?. If I use Where Field = 'abcdefghij', ie specify the value in the SQL I get the correct records selected but this does not give me the flexibility I need

I have a basic grid of Linq2Sql entities (frmList). I have a separate form for editing (frmEdit). frmEdit has its own DataContext (as that appears to be the recommended way). How can I tell when my detail form has saved changes?
I don't see a built-in method. I am considering raising an event on the detail form when I save the datacontex, but not sure how I consume this event on frmList, and I have a feeling these events are already created for me somewhere?

We have a reporting system where in we are getting unexpected results:
1) The size of reports at different time of interval is different?
2) The reports are writen as pdf to a directory. When we have thousand of older unused pdf(which will not get merged) in the directory the Adobe Life Cycle(to murge the PDF) throws error.But when we clear the directory by deleting the old unused pdf, it works fine?
3) Some of the pdf that are rejected by Adobe life cycle may or may not be corrupted. Meaning they may or may not open up with Adobe Reader, manually.

I have a data driven application in <acronym title="Visual Basic">VB</acronym> which works with an SQL Server 05 Database.Since this app makes use of many queries and commands, occasionally i'me getting a timeout error as the connection pool is full. So i figured that at a specifc point in time within the app,i'll clear the connection pools using the ClearAllPools method rather than increase max pool size.
I'm using the performance monitor on my XP development machine (NumberOfPooledConnections) however not once do i see the number of Pooled Connections reset to 0 even when that method is called.How can I determine that my solution is working (if it is) before I deploy the update?

always had a problem getting my head around it. I don't have a very strong mental model of how the code flows. My main problem is i think i understand the syntax, but not really its application. Any links people found useful would be great.
Couple of questions. The code below doesn't make sense to me (written by someone else) the application is basically a csv reader, but manipulates the data.
Public Sub entryType()

Let's say I have 3 tables: carts, baskets and eggs where a basket can contain many eggs and where carts contain many baskets. Each basket has a foreign key that maps to a cart and each egg has a foreign key that maps to a basket.I need to return a table that contains these 3 columns:Cart Name | Count of Baskets in Cart | Count of Eggs in Cart.Each table is an EF and I'm using linq with VB.So far, I have 2 queries: one that returns the columns Cart Name and Count of Basket and another one that returns Cart Name and Count of Eggs. How can I combine these two result tables so that I get the results in one table?
Dim query1 = (From cart In myEntities.Carts
Where cart.UserID = TheUserID
Join baskets In myEntities.Baskets On baskets.CartID Equals cart.CartID

I have an application that works together with a SQL database. This database has more than 40 tables and my applican has to extract different situations from those tables.
I have predefined some queries for the situations that I know they need to be in the application.
The idea is that I need kind of a module in which an user can create his own situation based on the tables, views, functions and procedures that already exist in the database. Something like it is in SQL. There has to be a library or something which will read my sql database directly from my application and which allow the user to create his own queries and situations.
