I'm currently doing a project which requires me to count a specific number of records who have a certain checkbox marked as true, passed questionnaire, it then needs to display this result in a textbox when the form is loaded. However i am having problems displaying the result in the textbox, this is my current code.
Imports System.Data
Imports System.Data.OleDb
Public Class frmCandidateGathering
[code]....
So I'm writing a query as follows:
Dim assSummary = From a In db.Assignments
Join ur In db.UserRegions
On a.Origin.ID Equals ur.Region.ID
[code]....
In the controller I can return the data easily as follows:
For Each c In assSummary
MsgBox(c.Description & " " & c.AssCount)
Next
If I pass the object through to the view using Viewdata("assSummary") = assSummary, how do I display the data? Every method I've tried results in messages about 'VB$AnonymousType_7(Of Integer,String) and I don't know how to retrieve the data from the anonymous type.
how to count the lines in textbox1.text (with multiplelines). I don't need to count each character. I only need to count each line from top to bottom in textbox1.text (multiplelines) and I will use Label1 to display the numbers.
example:
1-pauljaones
2-tommyperrry
3-marktoms
4-Jonessmith
5-paulwhite
Obviously this is 5 lines and that's what I need to count.
How do you carry out a query from a criteria e.g name entered by the user from a textbox. and then display the query results in a list box..
View 2 RepliesI am using VB2005 ASP/VB. I have a Gridview placed on a web form which is popluated by a query based on user input.select * from view_main where initials = ddlfilter.textThis works fine. However I want to display a realtime record count based on that query and dump the info in a label called 'recordcount' which appears at the bottom of the grid.
View 4 RepliesI'm trying to get a simple count of rows meeting some criteria. The value returned does not coincide with the correct number of rows when running the same query in Management Studio (SQL 2005)
vb.net
Public Function RowsAffectedCount() As Integer
Dim result As Integer = 0
[code]....
'result' always returns 1, but I have 3 records meeting that criteria in the database. Been staring at the code for a couple hours now and can't figure it out... I just need to know if the Count of rows returned from a SELECT statement is greater than 1 (at least two records).
My problem is i don't know how to query TOP ORDER PROD using COUNT,AVG...
-LIST OF ORDER'S-
ITEM CODE | ITEM NAME |
4323 PROD A
4323 PROD A
4323 PROD A
i don't know how display TOP ORDER PROD. using count and average
[code]....
-TOP ODER PRODUCT-
ITEM CODE | ITEM NAME | TOTAL NO. OF ORDERS | PERCENTAGE RATE
4323 PROD A 5 4.23%
2345 PROD B 3 2.33%
3462 PROD C 2 1.56%
I have a data table that looks like this:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012

LAGX11 5547 2011 05-07-2012
LAGX12 9456 3459 05-07-2012
Now, I want to execute a sql query that will display the top 5 based on average, so i did this:
SELECT DISTINCT USERNAME,IAVERAGE FROM myTable WHERE IAVERAGE > 0 AND DATE_LOGGED='05-07-2012' ORDER BY IAVERAGE LIMIT 0,5 and the result is:
USERNAME ICOUNT IAVERAGE DATE_LOGGED
LAGX03 1698 1112 05-07-2012
LAGX09 1598 1142 05-07-2012
LAGX06 3321 1155 05-07-2012
LAGX01 1245 1245 05-07-2012
LAGX02 2211 1422 05-07-2012
Now, I want to numberize my query result, so it will look like this:
RANK USERNAME ICOUNT IAVERAGE DATE_LOGGED
1 LAGX03 1698 1112 05-07-2012
2 LAGX09 1598 1142 05-07-2012
3 LAGX06 3321 1155 05-07-2012
4 LAGX01 1245 1245 05-07-2012
5 LAGX02 2211 1422 05-07-2012

I'm using VB.NET, and I'm trying to write a program for the company I work for, that interacts with a database designed for logging web site email submissions (After a user fills out a form for a item request or comment sheet, the email the form sends gets logged so we can more easily see which site gets spammed more, and we keep a record of the actual spam). My program mainly just makes the data easier to read. However, I want to add a feature so that a user can click a button, then an automatic query will take place so that all the preserved URLs in the database are tested, then a form will appear that states something along the lines of: These Sites Sent This Number of Emails
View 6 Replieshow to take a query that returns a single row of data and load that data into textbox controls.I know about ExecuteScalar but it is only good for a single column of data from the query.
View 2 RepliesI have the following SQL query to return all Customers who have no OrderLines with no Parts assigned - i.e. I only want the customers within which every order line of every order has no parts assigned - (in the actual problem I am dealing with a different domain but have translated to customers/orders to illustrate the problem)
SELECT c.Customer_PK
FROM Customers c
INNER JOIN Orders o[code].....
This works but generates less than optimal SQL - it is doing a subquery for Count on each row of the customers query rather than using Group By and Having. I tried making the LINQ Group By syntax work but it kept putting the filter as a WHERE not a HAVING clause.Edit in response to Answers below: I am accepting JamieSee's answer as it addresses the stated problem, even though it does not produce the GROUP BY HAVING query I originally had.I am a VB developer so I have had a crack translating your code to VB, this is the closest I got to but it does not quite produce the desired output:
Dim qry = From c In context.Customers
Group Join o In context.Orders On c.Customer_PK Equals o.Customer_FK
Into joinedOrders = Group[cod].....
The problem I had is that I have to push "jl" into the Group By "Key" so I can reference it from the Where clause, otherwise the compiler cannot see that variable or any of the other variables appearing before the Group By clause.With the filter as specified I get all customers where at least one order has lines with no parts rather than only customers with no parts in any order.
Is there a way to keep a counter inside a "for each" and display a count by a lable on a app?

I want to query an access database with variable data defined by the user. The "Search" criteria would be in a textbox. I made a query like
SELECT askID, Question
FROM chita
WHERE (askID LIKE 'Textbox10.text%')
and referring to this query as
Form1.ChitaTableAdapter.searchrec(Form1.ChitaDataSet1.chita)But id does not take the value of the textbox, instead it takes the Textbox10.text as a value. Is it possible to refer to it like this, or should I Linq?

I am trying to make a simple form that will display a count when the users clicks a button. I want the count to be readable as the program loops the math. So as it adds 1 + 1, 1 + 2, 1 + 3, ect... I want each loop to display in the label. Below is the basic code I came up with, but I can not figure out how put a delay of something like 100 milliseconds in the loop. The idea is for the slower version of the basic count console app you learn in school and I basically need to slowdown the math and display the sum as the loop loops.
Below is my code.
Private Sub xButton_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles xButton.Click
Dim xCount As Decimal ' Count
Dim xSum As Decimal ' Sum of loop
Do Until xSum >= 100 ' Limit the count
xCount += 1 ' Count by 1
xSum = xCount ' Sum = Count
xReadingLabel.Text = xSum ' Display Sum in Label
Loop
End Sub
cmd.CommandText = "select count (*) from inventory where qty <= crit"
cmd.Connection = sqlcon
dr = cmd.ExecuteReader
While dr.Read
lbl_count.Text = dr(" ").tosring
End While
how can I display the number of rows in string like label?
I've been working with my project. I make a quiz and I put check value for every label. If the user is correct the label with shows or else the label is in a hide status.

View 5 RepliesI am new to Visual Basic and I am having some problems with a programming challenge. The user is told to enter their city, state, and zip into a textbox seperated a certain way (Ex. City, State. Zip). The program is supposed to display the City, State, and Zip in three seperate label boxes broken up. So far the code that I wrote for the button click event displays the count up to where a comma is found (City). Im not sure how I would display the word instead of just the count. Also, finding the state and zip after the City is found. I know I have to use the IndexOf method as well as the Substring method.
Here is what I have so far:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click
Dim strCity, strState, strZip As String
Dim strInput As String = txtInputData.Text
Dim intCount As Integer
'Obtain the count for city
intCount = strInput.Length
strCity = strInput.IndexOf(",")
lblCity.Text = strCity
End Sub
How to i display how many records that i have in a label on my main form for example if i had 3 table called Cusotmers, Orders, Products

i have a form with some labels.. i need each label to display a text after certain time of the time count. i have this piece i put together.. didnt work but i guess it need a little professional touch.

The user has to enter the text in the textbox , to write a text user need to press the keys and release the keys. Write a code to count the number of keypresses and keyreleases and display the value in the labels.
View 1 RepliesI am currently building a search page, which includes a textbox and two drop-down lists, a search button, and a datagrid. If results are found and displayed, I would like a label to display:
(e.g.) "24 results found for 'blue sky clouds' "
...where the integer represents the results count, and the keywords and/or drop-down list selections are included in the string.If no results are found I would like the label to display:(e.g.) "No results were found that match your selection. Please try again"I would also like the label to be invisible until a search occurs.
I have a small application that consists of multiple forms that each need to have the ability to be updated (not repainted, the data/components values redefined) when called to. So for instance, if I had a form that contained a count of some sort and another form modified that count I would need to update the form that displays the current count. With that being said it needs to implement an interface with these methods (see below). My issue comes when I want to add events to these methods so if I call the UpdateData event it would trigger the OnDataUpdate method, but because of the syntax of implementing methods and handling events you cannot do so.

I'm making an app on wpf.Basically, I have a list view with 6 columns,For each item of the listview, its details are displayed are displayed in each of the columns, except the first.Basically I want the listview to automatically display a count of the items for the 1st column.[code]I have sorting and other weird stuff happening in the app, and I want to keep the first column constant. All that is needed from the column is that it counts the items.[code]I just realised this isn't vb .net so to speak.I code only on vb .net, but having trouble with that xaml bit atm. Would rather not use vb codes for solving this particular matter if possible
