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
I 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 am just wondering how I can make a listbox count the number of selected items and display it in a text label. My listbox selection mode is on MultiExtended.
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.
I have a directory searcher that is looking for dynamic groups.When I try to process the results it is taking 30 seconds to return the results.the ds.findall is very fast but when I try to find out the number of records returned or anything about the results it take the 30 seconds. So i am assuming that this is where the actual retreival of information is taking place.[code]

I have a data grid that i am getting the row count of and displaying it into a label. All works, but when there are 0 rows the label still shows 1.
This code updates the label when something changes in the datagrid:
Private Sub AuditProductsDataGridView_CellStateChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellStateChangedEventArgs) Handles AuditProductsDataGridView.CellStateChanged
I have been learning visual basic and this is my code I have Imports System.IO.StreamWriter Imports System.IO.StreamReader Public Class Form1 ' Form Load Dim w As IO.StreamWriter Dim r As IO.StreamReader [Code] .....
My problem is that I want label1 to count one when the information in Textbox5 is matching a line of info in Listbox1 so far I can do this but when the info changes by me pressing Ctrl+C it works it counts 1 but my problem is my clipboard info is updating automatically I can see the change in the textbox but it wont count.
I have a database with 1,000,000 records and a query like this:
select count(code) from table1
It works well on the local system but becomes very slow on the network. Other queries like select * from table execute quickly, but select count(code) from table1 is very slow. I can't change the database's structure. My database is Foxpro and I use VB.NET.
Edit: Should I write code like this?
dim ds as new dataset dim da as new datadapter("select count(*) from table ", connection) da.fill(ds,"tbl1")
Then how can I get select count(code) from table1 from the dataset? Or do I have to use LINQ?
Edit 2: I mean the comparison between select count(*) and select count(code).
I am new to VB.Net, but I can tell you so far I love programming. That said, I'm building a tool basically to parse and display simple plain text log files. I'm hitting one stumbling block that really has me frustrated.
Other tools are able to load huge log files (500MB even) in a number of seconds. My tool, basically hangs loading a file that is maybe 5MB.
I'm using the MyString = StreamReader.ReadToEnd to read the contents into a string, and then RichTextBox1.Text = MyString to display the contents. That said, I really want to display the contents in a datagrid, but there has to be a better way of doing this?
How can I get my application to load larger files and display them faster? What am I doing wrong?
I am having a mental block on how to work out a 15 minute timer that is shown on a label and counts down so that the user can watch it. I can do it just fine in seconds but I need to put it into the format of 15:00 and then have it count down the seconds and the the minutes when ever it drops 60 seconds. I found a few articles on using the dateNow syntax but that seems like it would only be good for adding time not subtracting it. Also I know I can set up a button to start and stop the timer but is it possible to use the space bar as the start/stop button?
I'm using a stored procedure in a sql database as the data source for a SqlDataSourceControl on my .aspx page. I'm then using the SqlDataSourceControl as the data source for a gridview on my page. Paging is set to true on the gridview. What i would like to do is set the text of a label to the total number of rows in the gridview. I can use this code
I am trying to count how many items are in an ArrayList and then save that into a Label variable that is updated each time an item's barcode is scanned.Information about the code below:rejectedList is the ArrayList that contains rejected parts.RejectedPartsNumberLabel is the label I am trying to update with the count from the ArrayList
Public Shared Function isFault(ByRef code As String) As Boolean rejectedList.Add(code) RejectedPartsNumberLabel.Text = rejectedList.Count Return (code.Length = 7 And IsNumeric(Mid(code, 1, 1))) Or (code.Length = 4 And Mid(code, 1, 2) = "NC") End Function
How can I keep a label on my form with the current count of the selected rows. My DGV has a checkbox (unbound) and 3 other columns. When the user clicks on the row I want the checkbox to either be checked or unchecked depending on its status and update a label the is below the DGV to show how many rows are checked. DGV is FullRowSelect.
I am using a label inside my loop to get a count on the number of records processed by the loop. during testing of the program I noticed that if I load a smaller Table( 1000 records) my label stops refreshing after about 110 and my mouse turns to an hour glass. The program finishes and the label returns the correct count when complete If I load a larger table (10,000 records) it works all the way through???
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
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. My problem now is how do I count those labels to display his/her result. If there are 3 labels shown in the form in automatically the user got 3 points and that "3" with be put into a textbox...
I 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
I have a label that is supposed to display a word for 5 seconds and then move down the list in a text file and display the next word.I'm oddly able to make it work in random mode, but not going down the list in order.. random would be ok if used words didn't come up again.
Code: Dim DurHold As String = My.Computer.FileSystem.ReadAllText(Application.StartupPath & "FlashWords.txt") Dim DurDelimiters() As String = {vbNewLine} Dim DurTextLines() As String = DurHold.Split(DurDelimiters, StringSplitOptions.RemoveEmptyEntries)
