Why my form loads takes time the first time I clicked the menu to load it (I even see not responding on the title bar), but when it is already loaded, I will close it and clicked the menu to load it again then it load fast already....
Here is what I have in my declaration section
Private cnn As New SqlConnection(My.Settings.MyConnectionString)
Dim cmdLocked As New SqlCommand
Dim daGrade As New SqlDataAdapter
Dim daLocked As New SqlDataAdapter
Dim builder As New SqlCommandBuilder
[Code] .....
I made two applications the first one calls the other. But the other application takes time to load. Even on a fast Pc. So i was thinking of adding a loading form to it. For example when the other application is done loading the loading form goes away.
i'm making a utility in which i'm loading 100,000 records again and again, problem is that it takes much time to load records in datagridview every time.
i've used data set and data reader both but same result. if i use paging then there's will be a problem of search a record on keyup event.
I have been working on a project of mine that will streamline some issues at the office. (Note: There is not much in way of documentation or comments as I just started on this)
This is what I have so far and I am getting this error:
"System.ObjectDisposedException was unhandled"
I can edit the database with the second form initally, but it pops up an error after I return to Form1 and then attempt to enter into the 2nd form any subsequent time after the first initial load.
Here is my code:
Option Strict On Option Explicit On Public Class Form1
I have a menu which when clicked will load form which take quite sometimes (although not very long) but the user keeps on clicking the menu and so the "not responding" message appears on the title bar of the app. I am thinking of displaying "Loading....Please Wait" so that users will stop clicking the menu or will wait until the loading of the form is completed. I tried these code but the form is still displayed even if form has loaded completely. [Code] I like to use the same concept also when the user clicked the save button, to tell the user to wait while changes are being saved.
I have a form with about 50 controls on it. labels, check boxes, combo boxes. text boxes and so on. Now I have a image on the back ground of the form and have made the checkbox text with transparent back ground so the picture can show through. the problem is that it is so slow to load. I see each one appearing on the form one by one. I have tried this on multiple machines and it does it on all of them. I have tried making the checkboxes not transparent but it still is slow.
how can I allow the form to load completely before it displays it. This is the initial form that loads and shows up.
i'm doing Advance search in my applications(vb.net,MS-Access) ,the results display form is quite heavy so i thought before loding the form i want to show some search icon

I am using word object for spell checking in richtextbox
in my program i have a timer, and every 5 sec (for example) i send a string by serial.i have to read every key pressed between each 5 sec and send a number that tells me what i am sending.what I've done is to send 1 as long as up key is pressed and send 8 as long as left key is pressed and send 9 as long as both are pressed.when i run my program, the first time i press up and left at the same time and i keep them pressed, the serial send me the first time 9 and then ignores the up key and send me 8 always.and sometimes send me 9 and after that always send me 1 and ignores the left key..the point is that vb ignores the first button i press even if i keep pressing it..what should i do to make vb.net takes two arrows keys at the same time?
Actually, I am trying to find out whether the partno is existing in the database table or not and it takes long time in count = checkCommand.ExecuteReader statement

The converted project takes too much time to load than previous vb6 project. What manual changes to the code should be done or is there any other option. Is it due to vb6 to vb.net conversion.
I'm trying to time how long an operation takes in Visual Basic (VS 2008) but its not working. the code I have is as follows:
[code]...
this is in an OnClick event, so what happens is that the user can click a menu item, and it goes and sends any changes it has to a database, and pulls down any new changes to a local data cache. This operation takes time, depending on how many changes are on the server and how many are cached locally. I've thought about making this a background task, so it doesn't draw away from the main app while it's running, but before doing that, I'd like to get an idea how long the operation takes. Since I can't exactly do a progress bar, I figured using the stopwatch would tell me how many ticks/milliseconds would occur between click, and when the "total synced" message comes up, but every time i run it and do an update the message always shows 0 ticks/ms. I don't think it's accounting for the delay, just from start to finish. Is there any way to make it so it detects a message popping up and times off that?
I ran into a problem where the listbox is taking awfully long time to show up. This is not the same in java(It took very very less time - one second max). So, is there any remedy to this??, any other form control??, or some other way?? imports System.Threading imports System.Windows.Forms
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 am using the below code to get the local Administrator members, but this code takes about 6-7 seconds to execute. More precisely the "GetObject" takes that long.Is there another way to get the same information but faster?Also, where can I find what other properties the objects holds ? (To see what other useful information I can get)[code]
Whenever I publish my app, or when I run the exe from teh debug folder it takes a couple of seconds before the splash screen shows.However, when I run it from within VB (by pressing the "play" button) the splash screen shows immediately.
I have the below code. What happens if the Upload method takes more than one minute for completion? Does the timer kick off another call to the Upload method immediately after one minute is over or Does it wait until the method finishes executing? I am implementing this as a windows service.
Protected Overrides Sub OnStart(ByVal args() As String) Dim tmr As Timer = New Timer(New TimerCallback(AddressOf Upload), Nothing, 1000, 60000) While Not tmr Is Nothing
I have 4k records in access database. And one of the field value contains ~100 lines each so and one other field has ~25 lines. So total database size reaches ~30MB and it takes lot of time 15-20 seconds to load the database in vb.net using odbc [URL]..and updating of any other small fields also takes time due to database being large
So as an alternative I used rtf file (txt files were not preserving all the newline characters). So these file are around 5-10kb only. But for 4k records and 2 fields I have now 8k files. And copying of these 8k rtf files is taking huge time for 5MB transfer it takes an hour or so.So is there any other alternative for storage of this data. So that it will be portable and easily loaded/accessed/updated from vb.net?
i have developed an application using OPEN XML SDK Tool 2.0 which generates Excel file. I have Data table of 100000 row and 30 columns and i want to generate excel file with these 100000 rows and 30 columns but it takes about 2 minutes of time to generate excel file. What can i do to reduce this time.
I tried using the web browser control for the first time.The problem I had was that the size of the web browser defaulted to the size of the form. Even when I tried to downsize the webbrowser ( via properties ) it still filled the entire form. I also tried to drastically increase the size of the form( again via the form's properties ), the web browser still filled the entire form. how to create a form where the web browser only takes up half the space of the form.
Ok, this might be something stupid that im not doing right, but here is my problem. Im moving from my 1st form, a small window, into my second form, that is full screen, but it takes like 4-5 seconds to load the full form. It sucks because during this 4-5 second load time, parts of the form at transparent and it just look bad. I think it might be because i have around 35 labels and a few other objects on the form. Does anyone know a way to make this not happen? Im in VB08.
In my new application i have to process a SQL statement.Depending on the settings , the statement takes between 10 an 20 seconds.is there a possibility to display a second from / dialog / popup for this time?
I'm trying to make a form that takes user input 3 times, and each time compares it to the correct Answer... which is an array of {"C", "D", "A"}.Each time the user's input matches the correct answer ("strCorrectAnswer()"), then I'll add 1 point to intUserScoreCounter. I'm wondering why this code is returning an error (hilighted in blue)? Can I not compare a String to an Array?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterAnswers.Click 'Handles Enter Answers functionality Dim strCorrectAnswer() As String = {"C", "D", "A"}
I was currently writting a Cyber Cafe for the client side which start up with a form that maximize and block all the client control like shortcut key and other security. It's fine to work in my pc and it take only about 5 second to startup the application and lock the client. But when i run the application in a pc that installed with games, it took about 40 second to run my apllication. I notice in task manager panel, the process need to read the whole application before it could load my first form. Is there any idea i can speed up my loading time? I have try to set the process priority to "real time" and startup using batch files, but it still need 30 second to load my first form.
